A review of the effects of peer tutoring on students with mild disabilities in secondary settings.Seventh-grade through 12th-grade students are expected to obtain knowledge and skills through various activities, such as teacher lectures and reading textbooks independently (Mastropieri, Scruggs, Spencer, & Fontana Fontana, city (1990 pop. 87,535), San Bernardino co., S Calif., at the foot of the San Bernardino Mts.; inc. 1952. Fabricated metal products, construction materials, and transportation equipment are manufactured, and there is a small steel mill. , 2003). Researchers recommend that teachers use these activities within a teaching cycle that has three interrelated in·ter·re·late

Three basic instructional arrangements can be employed during the teaching cycle: whole class, small group, and individual work (Hofmeister & Lubke, 1990). Teachers often use a whole-class instructional arrangement during the new material and guided practice phase of the teaching cycle where teachers present new material and question students about material learned previously. The advantages of a whole-class teaching arrangement are that teachers can easily provide extensive amounts of feedback for student responses and apply an entire teaching cycle. In a whole-class instructional arrangement, however, it is difficult to individualize in·di·vid·u·al·ize

See Problem-based learning, Socratic method. groups or work with each small group individually. An advantage of small-group arrangements is that it is easier to individualize content to meet each student's needs than in whole-class instruction. The disadvantage of Small group arrangements is that managing multiple groups can be difficult for teachers, and it is more difficult than whole-class instruction or small-group arrangements to provide the full teaching cycle. In individual work arrangements, students work independently on previously introduced knowledge and skills. During individual seatwork seat·work

Although the term dates to the thirteenth century, tailor content for each student in the class (e.g., students with varying math skills can practice specific skills that correspond with their needs). In individual seatwork, however, it is difficult for teachers to provide the full teaching cycle for each student, and opportunities to provide feedback are more limited. Moreover, maintaining high levels of task engagement often is more difficult during individual work than during whole-class or small-group instruction. Stallings (1980) reported that students who have more engaged time have higher achievement than students who have less engaged time.

This is especially important when teaching students with disabilities at the secondary level. These students typically have poor reading skills, poor note-taking skills, and poor organizational skills (Kavale & Forness, 2000; Marchand-Martella, Martella Martella is a spider genus of the Salticidae family (jumping spiders).

(1993) suggest that peer tutoring might be used during the independent-practice phase of the instructional cycle to build fluency and apply content information.

(1987) suggest that opportunities for individual responding are more frequent during peer tutoring than during teacher instruction. Moreover, peer tutoring might Be used to increase students' engaged time during independent practice when managing students is often difficult.
This literature review examines peer-tutoring research conducted in academic settings in the secondary grade levels with students with mild disabilities. The literature was examined to determine (a) the demographics The attributes of people in a particular geographic area. Used for marketing purposes, population, ethnic origins, religion, spoken language, income and age range are examples of demographic data. of tutors and tutees, (b) the content and skill areas where peer tutoring with students with mild disabilities are employed, (c) the tutor training needed for an effective tutoring program, and (d) the effect of tutoring on tutee and tutor performance. Finally, studies are assessed to determine whether practices employed by the researchers are identified as evidence-based practices.

See GPS. ) for single-subject studies. The reference sections of articles that met these criteria were reviewed for additional studies. Initially, 26 studies were identified; 6 were eliminated because they did not provide data to compute effect sizes or PND, thus 20 studies were reviewed.
The study characteristics coded in the review are (a) study setting; (b) tutor and tutee characteristics; (c) skill and content domains (e.g., reading, mathematics, social skills, history) and dependent variables; (d) type of peer tutoring used; (e) peer-tutor training and whether the tutors were matched to tutees prior to peer tutoring; (f) whether there was monitoring of tutor behavior and evidence of treatment fidelity; and (g) whether teachers problem solved with tutors after peer tutoring sessions.
The literature analysis is divided into three sections: (1) a synthesis of the studies' demographics, including the peer-tutoring setting, tutor and tutee characteristics, skill, and content domains in which tutoring was employed; (2) a summary of study outcomes; and (3) conclusions.
Study Setting. Peer-tutoring research has been conducted in a broad range of classroom settings, including general education classrooms, remedial REMEDIAL.

Five of the 20 studies (25%) were conducted in a general education setting and 13 of the 20 studies (65%) were conducted in a remedial classroom, resource classroom, or self-contained special education classroom. One study was conducted in a resource classroom and general education classroom (Hogan hogan

n. , 1993). Another study was conducted in a correctional-facility school (Kane Kane can refer to:
an area in a cow barn identified by its particular purpose such as a loafing alley, a walking alley or feeding alley. , 1980). The type of tutoring used also varied across studies. Most researchers used heterogeneous peer tutoring (n = 9). The second most-used tutoring type was reverse-role tutoring (n = 8), and homogeneous peer tutoring was used in only 2 studies, and cross-age peer tutoring was used in 1 study.
Tutor and Tutee Characteristics. The tutor and tutee characteristics included the participant's age and grade, whether they were from the same class or recruited from different classes (origin), and whether they had a disability (Table 1). It was noted whether the tutors also served as tutees, and whether the authors reported the disability category in each of the studies.
Tutors were in 7th to 12th grades and their reported ages ranged from 10 to 21 years (Table 1). Tutors overwhelmingly were recruited from the tutees' class (n = 16). In one study, tutors were recruited from a peer buddy class (Presley & Hughes, 2000). In three studies the tutors' origin was not indicated (Bell et al., 1991; Blake, Wang (Wang Laboratories, Inc., Lowell, MA) A computer services and network integration company. Wang was one of the major early contributors to the computing industry from its founder's invention that made core memory possible, to leadership in desktop calculators and word processors. , Cartledge, & Gardner, 2000; Hogan & Prater, 1993).
In most studies the tutors included students with disabilities (learning disabilities, behavior disorders, mental retardation mental retardation, below average level of intellectual functioning, usually defined by an IQ of below 70 to 75, combined with limitations in the skills necessary for daily living. [mild mental retardation, educable educable /ed·u·ca·ble/ (ej´u-kah-b'l) capable of being educated; formerly used to refer to persons with mild mental retardation (I.Q. approximately 50–70). mentally retarded Noun 1. mentally retarded - people collectively who are mentally retarded; "he started a school for the retarded"

2. ). In 8 of the studies, tutors did not have a disability (Bell et al., 1991; Kane & Alley, 1980; Maheady, Sacca, & Harper, 1987; Maheady, Sacca, & Harper, 1988; Nobel Nobel

See : Prize , 2005; Presley & Hughes, 2000; Smith, Young, Nelson, & West, 1992; Stevens, 1998). In 11 of the studies, the tutors also served as the tutees.
Tutees were in 7th to 12th grade and their ages ranged from 12 to 21 years. Tutees' disabilities included behavior disorders (35%), learning disabilities (65%), and mental retardation (27%). The total number of tutees across all studies was 298 (M = 15; range = 1-58).
Skill and Content Domains. Peer tutoring was examined as an instructional strategy to increase tutees' proficiency pro·fi·cien·cy
n. pl. pro·fi·cien·cies
The state or quality of being proficient; competence.
Noun 1. proficiency - the quality of having great facility and competence in skill areas or to teach content knowledge. In 60% of the studies, tutees' basic reading, vocabulary, spelling, math, and social skills were addressed. Improving basic academic and social skills often is critical for improving students' ability to comprehend content independently, respond to questions in content-area texts, and enable greater levels of participation and interaction with teachers and peers (Marchand-Martella et al., 2000; Prater, Serna, & Nakamura Nakamura may refer to:
The primary dependent variable in 18 studies was correct responding (e.g., reading rate, rate of correct responses per minute on paper-and-pencil driving procedure tests, percentage of correct math problems, content chapter test scores, providing feedback to peers, anger management steps completed correctly) and the primary dependent variable in 2 studies was on-task behavior. In the majority of the studies, researchers used curriculum-based assessments (CBAs) to measure tutee outcomes (e.g., rate of responding, percentage of correct responding, tutee statements, tutees' grades). Fuchs et al. (1999) conducted the only study that used a standardized assessment to evaluate student improvement as a result of their heterogeneous peer tutoring program (Tables 2 and 3).

3. by calculating an effect size for the primary dependent variable in group design studies (n = 6), or the percentage of nonoverlapping data points for the primary dependent variable in single-subject design studies (n = 14). Unbiased-mean standardized-difference effect sizes were computed for group studies. This effect size was used because it tends to minimize the upward bias in smaller sample sizes as standardized mean difference effect sizes do (Lipsey & Wilson Wilson, city (1990 pop. 36,930), seat of Wilson co., E N.C., in a rich agricultural region; inc. 1849. It is a commercial and industrial center with a large tobacco market. Manufactures include textile goods (especially clothing), metal products, and processed foods. , 2001). Next, effect sizes for each study's primary dependent variable(s) were averaged into a weighted mean effect size to report 1 effect size per study (Table 2; Lipsey & Wilson). All effect sizes reflect outcomes for students with disabilities except for 1 study (Roach et al., 1983). The effect size for this study includes students in a remedial mathematics course who qualified for special education or for remedial services in math. Finally, an over all weighted-mean effect size was calculated. For this review, an effect size ranging from 0.20 to 0:49 was considered small, an effect size ranging from 0.50 to 0.79 was considered medium, and an effect size of 0.80 or greater was considered large (Howell How´ell

For each participant in single-subject studies, the PND was computed by dividing the number of data points exceeding the highest (in studies in which an increase in the dependent variable was expected) or lowest baseline The horizontal line to which the bottoms of lowercase characters (without descenders) are aligned. See typeface.

The PND for each participant then was averaged across participants to yield a mean PND for each study. For this review, mean PND scores greater than 90% indicate that the intervention was very effective, scores falling between 70% and 89% indicate that the intervention was effective, scores falling between 50% and 69% indicate that the intervention was minimally effective, and scores falling below 50% indicated that the intervention was ineffective (Graham & Harris Harris, Scotland: see Lewis and Harris. , 2003).
Gersten and colleagues (2005) and Horner and colleagues (2005) describe criteria used to assess whether practices are supported as being evidence based. When evaluating group research, Gersten et al. propose that a practice is evidence based if there are, "at least four acceptable quality studies, or two high quality studies that support the practice" (Gersten et al., p. 162) and the weighted effect size statistically is significantly greater than zero. Gersten et al. also provide study quality indicators for reporting participant information, intervention and comparison conditions, outcome measures, and results (see Gersten et al. for further discussion of the criteria). When evaluating single-subject research Single Subject Research Designs

This group of research methods is used extensively in the experimental analysis of behavior in both basic and applied settings with both human and non-human , Homer Homer, principal figure of ancient Greek literature; the first European poet. Works, Life, and Legends
Two epic poems are attributed to Homer, the Iliad and the Odyssey. et al. propose the following quality indicators: the practice is clearly and operationally defined, the context and outcomes of the practice are clearly defined, and there is a functional change between the independent variable and dependent variable. For this review, the mean PND score was used to evaluate the strength of the functional change between the independent variable and the primary dependent variable for each study.
Further, Homer and colleagues (2005) suggest that (a) experimental control must be demonstrated across a minimum of five studies published in peer-reviewed journals; (b) the studies must be conducted by at least three different research teams in three different settings; and (c) the five studies must include at least 20 participants (see Homer et al. for further discussion on the criteria). Finally, in both group and single-subject research, Gersten et al. and Homer et al. suggest that documented procedural fidelity is a desirable quality indicator.
All but three studies in the present review were published in peer-reviewed journals. Nobel's (2005) and Stevens's (1998) single-subject studies were dissertations and Terrell Terrell (tĕr`əl), city (1990 pop. 12,490), Kaufman co., N Tex.; inc. 1883. In a farm area, cattle and horses are raised and there are nurseries; peaches, cotton, and wheat are grown. and Feldman's (1983) single-subject study was published in a conference proceeding. Only three of six group studies reported effect sizes, an important quality indicator (Gersten et al., 2005). Finally, few studies reported treatment fidelity (group, n = 1; single-subject, n = 6). In one study (Stowitschek Hecimovic, Stowitschek, & Shores, 1982), however, the range was reported and a mean could not be computed. The treatment fidelity in the Fuchs et al. (1999) group study was 86.3%. The mean treatment fidelity across single-subject studies was 99% (n = 5, range = 96% to 100%). Importantly, in studies in which treatment fidelity is included, the data reported are uniformly strong.
The following section reports outcomes for group studies and then for single-subject studies. The studies are categorized cat·e·go·rize

cat by their primary dependent variable (i.e., correct responding or on-task behavior). The studies are separated into these two categories because the measures appeared to be the most relevant for analysis of peer-tutoring effects. For group studies, a mean weighted effect size is reported for the primary dependent variable(s) in each study, and an overall mean weighted effect size represents all the group studies. Based on the recommendation put forth by Gersten et al. (2005), however, the overall mean weighted effect size is reported for categories (e.g., correct responding or on-task dependent measures, type of tutoring employed) in which there are four or more group studies that represent that category.
For single-subject studies, a mean PND is reported for the primary dependent variable(s) in each study and an overall PND is reported for all single-subject studies. Additionally, based on the recommendation in Homer et al. (2005), the overall PND is reported for categories in which there are five or more single-subject studies that represent that category. Finally, suggestions for general practice are discussed following each section, based on criteria for evidence-based practice provided by Gersten et al. (2005) and Homer et al. It is important to approach the outcomes cautiously, given the qualitative aspects of some of the criteria that Gersten et al. and Homer et al. suggest, such as whether the dependent variables or peer-tutoring interventions are "clearly" described; whether "sufficient" information is provided to confirm participants' disabilities, and that treatment fidelity was reported in less than half the studies reviewed.
MAGNITUDE OF OUTCOME
Mean weighted effect sizes were computed for 30% of the studies reviewed (Table 2), and the percentage of nonoverlapping data points was computed for 70% of the studies reviewed (Table 3).
Overall Outcomes for Correct Responding Group Studies. All group studies (n = 6) were categorized in the correct responding category. The 6 effect sizes ranged from 0.18 to 1.15. Two effect sizes were considered small, 1 was considered medium, and 3 considered large. The overall weighted mean effect size across the group studies was 0.46 (CI = 0.41 to 0.71). The homogeneity test was statistically significant (Q = 24.24, p < 0.05). This indicates that the variability of the effect size is larger than is expected from sampling error. Results from the group design studies therefore must be interpreted with caution.
Overall Outcomes for Correct Responding Single-Subject Studies. Of the 12 single-subject studies in which the primary dependent measure was correct responding, 5 mean PND scores were in the minimally effective interval, 5 mean PND scores were in the effective interval, and 2 mean PND scores were in the very effective interval. Overall, the mean PND across studies was in the effective interval (MPND= 74%; range = 50% to 98%).
Overall Outcomes for On-Task Single-Subject Studies. There were only two studies that were categorized in the on-task dependent measure category (Hogan & Prater, 1993; Smith, et al., 1992). A reliable overall PND therefore could not be Computed, and the two studies are not included in subsequent analyses. In one study, the mean PND was in the ineffective interval (PND = 33%), and in the other study a very effective PND was computed (PND = 100%).
General Practice Summary. Both effect sizes and PND effects tended to be dispersed dis·perse

a. To drive off or scatter in different directions: The police dispersed the crowd.
b. across all levels of effects. Four of the 6 group studies support peer tutoring as an evidence-based practice. Eight of the 12 single-subject studies in Which correct responding was the primary dependent variable were published in peer-reviewed journals, 7 different research groups conducted the studies, and there were 89 participants across the peer-reviewed studies. Additionally, researchers clearly described the study methodology in each of the studies. In both the group and single-subject studies, the researchers generally met the quality and outcome standards for peer tutoring to be considered an evidence-based practice for students in secondary settings.
HOW DOES TUTORING TYPE AFFECT TUTEE OUTCOMES?
Four tutoring types were identified in this review: reverse-role, heterogeneous, homogeneous, and cross-age. Reverse-role tutoring was used in three group studies and in five single-subject studies in which correct responding was the primary dependent variable (Table 1). Heterogeneous peer tutoring was used in two group studies and in five single-subject studies. Homogeneous tutoring was used in one group study and one single-subject study. Cross-age tutoring was used in one single-subject study. Tutoring-type effects are analyzed for single-subject studies only, because there are fewer than four studies in any one tutoring-type category across the group studies.
Tutoring-Type Effects for Correct Responding Single-Subject Studies. In two studies, reverse-role tutoring was considered minimally effective (MPND = 58%, range = 50% to 65%; Table 4). In three reverse-role tutoring studies the effects were considered effective (MPND = 78%, range = 73% to 88%). Overall, the mean PND across studies in which reverse-role peer tutoring was used was in the effective interval (M = 70%; range = 50% to 88%). In studies that used heterogeneous peer tutoring, the PND in one study was considered minimally effective (PND = 65%), the PND in two studies was considered effective (MPND = 79%, range = 74% to 84%), and the PND in two studies was considered very effective (MPND = 98%, range = 97% to 98%). Overall, the mean PND across studies in which heterogeneous peer tutoring was used was in the effective interval (MPND = 84%; range = 65% to 98%). There were not enough studies included to enable computation Computation is a general term for any type of information processing that can be represented mathematically. This includes phenomena ranging from simple calculations to human thinking. of a reliable average PND for tutoring-type effects for homogeneous (PND = 53%) and cross-age tutoring (PND = 69%).
General Practice Summary. In general, the single-subject studies support reverse-role peer tutoring as an evidence-based practice. Only three of the five single-subject studies in which reverse-role peer tutoring was used were published in peer-reviewed journals, however, and they all were conducted by one group of researchers. Thus, the single-subject studies do not meet the necessary quality standards (Homer et al., 2005). A heterogeneous peer-tutoring approach was supported as an evidence-based practice in the single-subject studies. Five single-subject studies in which heterogeneous peer tutoring was used were published in peer reviewed journals, five different research groups conducted the studies, and there were 25 participants across studies. Additionally, the researchers clearly specified the study methodology in each of the studies. No recommendation can be made regarding homogeneous and cross-age peer tutoring because these factors were not used in a sufficient number of studies.
In sum, it is clear that peer tutoring at the secondary level qualifies as an evidence-based practice; however, there is not sufficient evidence to suggest that some peer-tutoring approaches are effective and other peer-tutoring approaches are ineffective.
HOW DOES TRAINING PEER TUTORS AFFECT TUTEE OUTCOMES?
Utley et al. (1997) report that peer tutors who use specific instructional behaviors are more effective than those tutors who merely are paired with another individual. Carnine (2002) identified important elements of effective tutor training. Teachers should (a) establish expectations with tutors, (b) model instructional-presentation behaviors, (c) provide opportunities for tutors to role-play role-play

Salter et al, Comp Langs 5(3):163-189 (1981)]. with Carnine's assertions (e.g., Delquadri, Greenwood, Whorton, Carta, & Hall, 1986; Fulk Fulk (fŭlk), 1092–1143, Latin king of Jerusalem (1131–43), count of Anjou (1109–29) as Fulk V, great-grandson of Fulk Nerra. & King, 2001; Hawkes & Paolucci-Whitcomb, 1980; Kline, 1987; Marchand-Martella et al., 2000; Roach et al., 1983; Utley et al., 1997). For example, Kline (1987) argues that using a highly structured daily lesson format provides tutors with a clear understanding how to conduct lessons, while easing the planning and training demands on the teacher. Additionally, Fulk and King describe implementation guidelines guidelines,
n.pl a set of standards, criteria, or specifications to be used or followed in the performance of certain tasks. for peer tutoring including matching tutors to tutees, training tutors to provide feedback for correct responses, performing error-correction procedures, and providing time to practice these skills before tutoring.
In 11 of the studies, teachers or researchers taught tutors instructional and management strategies prior to the beginning of the tutoring sessions (Table 5). In 10 of these studies, researchers or teachers modeled instructional-presentation behaviors, and had peer tutors role-play or practice those behaviors. Additionally, researchers or teachers modeled or had peer tutors role-play and practice reinforcer delivery and corrective feedback. Fulk and King (2001) and Fuchs, Fuchs, Mathes, and Simmons (1996) suggest matching students by initially ranking students from highest achiever to lowest achiever in the peer-tutoring content area. Next, the list is divided in two and the first student on list one is paired with the first student on list two, the second-ranked student on list one is paired with the second-ranked student on list two, and so on. Allsopp (1997) emphasizes the importance of this method of pairing because it allows students with differing abilities to work together while allowing more skilled students to teach students that have lesser skills. Jenkins and Jenkins (1988), however, suggest that the more critical factor in matching tutors and tutees is matching their personal characteristics. For example, Haisley et al.

In nine of the studies, tutors and tutees were matched before peer tutoring began (Table 5). In six studies, high-performing students were matched with lower performing students. Maheady et al. (1987), for example, ranked students by math competency level from highest to lowest. Students then were assigned as·sign

Group members remained in the same group for 4 to 6 weeks. Mastropieri et al. (2003) matched tutors and tutees based on who would be more likely to work well together, but did not describe the basis for deciding whether students would work well with each other. Franca, Kerr, Reitz, & Lambert Lambert may refer to
The amount of tutor training varied across studies. In general, studies in which researchers provided more-extensive tutor training produced better results than studies in which researchers provided less-extensive training. For example, Stowitschek et al. (1982) provided extensive training for tutors that included establishing expectations with tutors, modeling instructional-presentation behaviors, providing opportunities for the tutor to role-play presentation behaviors and feedback behaviors, and practicing monitoring tutee performance. In contrast, Blake et al. (2000) modeled presentation behaviors and provided opportunities for tutors to practice the presentation behaviors.
Training Effects for Correct-Responding Group Studies. The 4 mean weighted effect sizes ranged from 0.25 to 1.15 (Table 6). One effect size was considered small and 3 were considered large. The mean weighted effect size across the four group studies in which peer tutor training was conducted was 0.91. The mean effect size was large and was statistically significant (p < 0.05, 95% CI = 0.62 to 1.20). Additionally, the test for homogeneity was not statistically significant (Q = 5.49, p > 0.05). This indicates that the dispersion dispersion, in chemistry

A dispersion is classed as a suspension, colloid, or solution. of effect sizes is no greater than expected from sampling error alone. Thus, it appears that the training of tutors had a great effect on tutee outcomes.
Training Effects for Correct Responding Single-Subject Studies. A similar pattern was observed in single-subject studies in which peer-tutor training was conducted (n = 8; Table 7). In three of the studies, the PND was considered minimally effective (MPND = 61%, range = 53% to 69%). In three studies, the PNDs (MPND = 77%, range = 74% to 84%) were considered effective. Finally, the PND in two studies was considered very effective (MPND = 98%, range = 97% to 98%). Overall, the mean PND across studies that included tutor training was in the effective interval (MPND = 76%, range = 53% to 98%).
General Practice Summary. Clearly, the mean weighted effect size supports a tutor-training component, and there are enough group studies to consider tutor training as an evidence-based practice. Six single-subject studies were published in peer-reviewed journals, six different research groups conducted the studies, and there were 27 participants across studies. Moreover, in all the studies, researchers clearly operationalized their training procedures and peer-tutoring practice, and the overall effect of the peer-tutoring interventions is in the effective PND interval. In sum, the group and single-subject peer-tutoring studies that include a tutor-training component generally meet the quality and outcome standard to be identified as an evidence-based practice.
HOW DOES MONITORING PEER TUTORS AFFECT TUTEE OUTCOMES?
Researchers recommend that teachers monitor tutors' instructional delivery, reinforcement reinforcement /re·in·force·ment/ (-in-fors´ment) in behavioral science, the presentation of a stimulus following a response that increases the frequency of subsequent responses, whether positive to desirable events, or delivery, error corrections, and tutee performance monitoring during instructional sessions (Canine canine
Any domestic or wild dog or doglike mammal (e.g., wolf, jackal, fox) in the family Canidae, found throughout the world except in Antarctica and on most ocean islands. , 2002; Fulk & King, 2001; Maheady, Harper, & Mallette, 1991; Maheady, Harper, & Sacca, 1988a; Maheady, Sacca, & Harper, 1987; Maheady, Sacca, & Harper, 1988). Teachers also should hold regular meetings with tutors after the tutoring sessions to provide general feedback on tutoring and to solve problems that can arise during peer-tutoring sessions (Carnine; Delquadri et al., 1986; Franca et al., 1990; Fulk & King, 2001).
In 15 of 18 studies in which correct responding was the primary dependent measure, the researchers indicated that the teacher or researcher monitored tutors' instructional skills during tutoring sessions or provided feedback to tutors after tutoring (Table 5). However, researchers reported specific tutoring behaviors the teacher or researcher monitored in only 10 of the studies (n = 1 group and 9 single-subject). The behaviors monitored most frequently included tutors' instructional presentation, reinforcement delivery, and corrective feedback. In some studies, teachers also tracked how tutors monitored tutee performance (Bell et al., 1991; Nobel, 2005; Maheady, Harper, & Sacca, 1988a; Stowitschek et al., 1982). Maheady, Harper, and Sacca (1988a), for example, taught teachers in a general-education social studies class to move around the classroom during peer tutoring and to provide points to tutors who were appropriately asking tutees questions, providing praise and error corrections, and recording tutees' scores. The points were totaled weekly, and the team with the most points was recognized in a class bulletin and given a certificate. In several studies, teachers or researchers met with peer tutors after peer-tutoring sessions to provide feedback on their teaching and performance monitoring, or to problem-solve peer tutoring issues. In the Stowitschek et al. (1982) study, the teacher met with tutors to provide feedback on tutoring procedures only. The researchers, however, did not report specific tutoring issues discussed or specific feedback given during sessions, and verification of whether issues were resolved was not provided. Additionally, there were no data provided that indicated whether the discussions influenced tutor behavior during tutoring.
Monitoring Effects for Group Studies. The 5 mean weighted effect sizes ranged from 0.18 to 1.15. One effect size was near 0, 1 was medium, and 3 were large. The mean weighted effect size across the five group studies in which peer tutor monitoring was conducted was 0.47 (Table 8). The mean effect size for the studies in which tutors were monitored was considered small and was statistically significant (p < 0.05, CI = 0.32 to 0.62). Further, the homogeneity test was statistically significant (Q = 23.82, p < 0.05), indicating that the variability of the effect size is greater than expected from sampling error. Therefore, the results from the group design Studies should be interpreted cautiously.
Monitoring Effects for Single-Subject Studies. PNDs were computed for 10 studies in which tutors' instructional skills were monitored (Table 9). In 4 of the studies, the PNDs were considered minimally effective (MPND = 63%, range = 53% to 69%), 5 were considered effective (MPND = 79%; range = 73% to 88%), and 1 was considered very effective (PND = 97%). Overall, the mean PND across studies in which peer tutors were monitored was 74% (range = 53% to 97%) and was considered effective.
General Practice Summary. There is not enough evidence to support peer-tutor monitoring with the group studies alone. Although the effect size was statistically significant the mean effect was small, and the outcome of the homogeneity test indicates that these results should be interpreted with caution. Also, researchers in five studies indicated that they monitored tutor behavior; however, the tutor behaviors that were being monitored was clearly defined in only 1 of the group studies.
Although the group peer-tutoring studies that included a peer-tutor monitoring component lack some quality and outcome standards that are necessary to be identified as evidence based, the single-subject peer tutoring Studies meet the quality and outcome standards to be an evidence-based practice. Eight single-subject studies were published in peer reviewed journals, seven different research groups conducted the studies, and there were 114 participants across studies. Additionally, the researchers clearly defined the specific tutor behaviors in all of the studies. Finally, the overall effect of the peer-tutoring interventions is in the effective PND interval.
In this review, the demographics of tutors and tutees, the content and skill areas in which peer tutoring was employed, the training needed for peer tutoring to be successful, and the effect of tutoring on tutee and tutor performance are examined. Finally, the studies are analyzed by correct responding studies and on-task behavior studies to determine evidence-based practices for peer tutoring in secondary settings.
Peer tutoring was conducted in several settings (e.g., general education classrooms, resource classrooms, self-contained classrooms), and primarily addressed basic academic and social skills (e.g., reading, vocabulary, spelling, math, feedback to peers, anger management). In the studies reviewed, all weighted effect sizes for primary dependent variables were positive. In single-subject studies, the mean PND across studies for the primary dependent variable was in the effective range. There were noticeably no·tice·a·ble

2. Worthy of notice; significant. few studies (n = 5) conducted in general education classes. Of those studies, two were implemented in content classrooms (social studies and driver education) and three studies were implemented in basic skills classes (reading, math, social skills).
One goal of this review is identification of the components of peer tutoring--in both group and single-subject studies--that are identified as evidence-based practices in secondary settings. Four evidence-based practices are identified in studies in which correct responding was the primary dependent variable.
1. Peer tutoring, as a general method, is supported as an evidence-based practice in both group and single-subject studies.
2. Heterogeneous peer tutoring is the only type of peer-tutoring method identified as an evidence-based practice. The studies supporting heterogeneous peer tutoring all are single-subject studies.
3. In both group and single-subject studies there is strong support for peer-tutor training prior to the commencement of peer-tutoring sessions.
4. The single-subject studies support monitoring peer tutors during peer tutoring as an evidence-based practice.

Thus, due to the dearth of evidence, no inferences regarding the efficacy of using peer tutoring with multicultural students or English-language learners with disabilities can be made at the secondary level. Utley and colleagues (1997) noted that peer tutoring has been used effectively with multicultural and bilingual bi·lin·gual

Additional research is needed to assess the effects of peer tutoring on students from diverse backgrounds with disabilities in secondary settings. It is important to examine whether the linguistic and cultural backgrounds of tutors have differential effects on tutoring and whether the tutoring procedures found in many of the studies reviewed here also are effective with multicultural students and English-language learners with disabilities.
As students enter secondary settings, the academic focus shifts from basic skills to content knowledge (Smith, Polloway, Patton, & Dowdy dow·dy

n. pl. , 2004). Moreover, IDEA 2004 emphasizes the need to provide students with disabilities access to the general curriculum, and clearly accentuates the need for strategies that support students with disabilities in content-area classes. Peer tutoring provides the structure needed to support basic skill deficits while allowing students to gain content knowledge (Maheady, Sacca, & Harper, 1988). Maheady, Harper, and Sacca (1988a) used peer tutors to quiz A quiz is a form of game or mind sport in which the players (as individuals or in teams) attempt to answer questions correctly.

See Bible. . There were five studies conducted in general-education classes identified in the current review, but there were no studies that addressed more complex content syntheses or content applications. For example, social studies or history questions that address the relationship between the causes and outcomes of historical wars with current wars or struggles require critical thinking and a deep understanding of factual knowledge. Although factual knowledge clearly is a prerequisite to addressing these kinds of questions, it would be interesting to examine whether peer tutoring is an effective instructional arrangement to develop critical-thinking skills in content areas. This research is necessary to understand the variety of knowledge that teachers might productively use peer tutoring to teach.

(1976) reported that there is little research that indicates what type of tutor (e.g., cross-age, heterogeneous, homogeneous) is most effective for students at the elementary or secondary levels. Based on this review, it is clear that additional research is needed to determine whether some tutoring approaches are effective and other tutoring approaches are not effective.

3. Expressive of a mood, especially a sullen or gloomy mood. (1999) reported positive effects when same-age peers with higher skills were used as tutors, when same-age peers with similar skills were used as tutors, and when reverse-role tutoring was employed. In contrast, they found that cross-age tutoring was not effective for tutees with disabilities. Elbaum et al., however, reported that the majority of participants were in first through sixth grades, but did not delineate the number of participants in secondary settings. Thus, it remains unclear whether the effect of cross-age tutoring is different at the secondary level than it is at the elementary level.
Another potentially important aspect of peer tutoring is the effect it might have on the tutors' performance. In the present review this aspect is not examined due to an insufficient number of studies; however, researchers have reported benefits of tutoring for tutors. It has been reported, for example, that secondary-aged tutors demonstrated academic gains (Maheady, Harper, & Mallette, 1991); reduced school absences (Maheady et al., 1991); increased positive social interactions (Maheady et al., 1991); and increased appropriate classroom behavior (Hogan & Prater, 1993). Elbaum et al. (1999), in a review of studies of elementary-grade peer tutoring, reported positive effects for cross-age tutors that have disabilities who work with students in elementary grades (i.e., first grade through sixth grade), but did not report the ages of cross-age peer tutors. In examining the benefit for peer tutors who were not tutees at the secondary level, it could be necessary to study what types of tutoring (e.g., reverse-role tutoring, cross-age tutoring), what skill or content areas, and what settings could have the greatest benefit for tutors.
One important factor that could influence the outcome of peer tutoring is peer-tutor training. This review supports researchers' (Carnine, 2002; Delquadri et al., 1986; Fulk & King, 2001) assertion that peer-tutor training is an important component of peer tutoring. In fact, the outcomes of this review support tutor training as an evidence-based practice. This finding aligns with the Maheady et al. (1991) report that the most effective peer-tutoring programs are those in which tutors are taught explicit teaching strategies. Generally, tutee outcomes were better when researchers provided more extensive tutor training than when researchers provided less extensive tutor training. Although this difference is evident when comparing studies where tutors are provided large amounts of training (e.g., Stowitschek et al., 1982) with studies where tutors are given less training (Blake et al., 2000), more evidence is needed to gain a clearer understanding of the effect of specific components of tutor training on tutee outcomes. It would be useful to evaluate specific components of tutor training to determine how they contribute to tutee achievement.
Researchers also recommend monitoring tutors during and after tutoring sessions. In most studies in which tutors were trained, researchers monitored tutors' instructional skills during tutoring sessions. This aligns with the suggestions of Maheady et al. (1991) and Jenkins and Jenkins (1988) that teachers should monitor peer tutors' instructional accuracy on an ongoing basis. Jenkins and Jenkins indicate that ongoing monitoring of tutors' instructional behaviors informs teachers regarding where additional tutor training is needed. In the majority of the studies reviewed, researchers monitored tutors' implementation of peer tutoring during the tutoring sessions. Ongoing monitoring is important, but researchers suggest that meeting with tutors after tutoring sessions also is important (Carnine, 2002; Delquadri et al., 1986; Franca et al., 1990; Fulk & King, 2001).

2. , teachers met with tutors after monitoring tutoring sessions in only 3 studies (Franca et al.; Haisley et al., 1981; Stowitschek et al., 1982). Future research could address what types of post-tutoring session teacher feedback are critical (e.g., opportunities to respond, praise per minute) and the extent to which peer tutors are more likely to maintain those behaviors.
Although there are a number of questions about how best to implement peer tutoring and how to determine the precise amount of training required for effective peer tutoring, it is clear that structured peer tutoring that addresses basic academics, social-skills instruction, and factual knowledge provides improved achievement among students with disabilities in secondary settings. Maheady, Harper, and Sacca (1988b) suggest that preservice teachers should be taught how to use peer-tutoring arrangements in their classrooms. They indicate that peer-tutoring arrangements provide teachers with another option to help students access the general curriculum, and support students with mild disabilities in secondary settings. In fact, the Council for Exceptional Children (2005) contends that highly qualified special education and general education teachers should collaborate to "design appropriate learning and performance accommodations for students with disabilities" in content-area classes. Peer tutoring has been shown to be an effective accommodation for students with disabilities to access the general-education curriculum, though the research is limited (Bell et al., 1991; Maheady, Sacca, & Harper, 1988; Mastropieri et al., 2003, Nobel, 2005; Spencer et al., 2003).
Researchers have shown that peer tutoring is an effective method to assist students with disabilities in accessing curriculum. However, more research is necessary to assess the extent to which peer tutoring can be used to assist students with disabilities access the general-education curriculum in secondary settings. In addition, researchers should examine how peer tutors could teach varying types of content knowledge within general-education settings. Within that context, researchers should report whether tutor training and monitoring was conducted and indicate the specific procedures used to conduct training and monitor peer tutors. Researchers also should attempt to use the quality indicators put forth by Gersten et al. (2005) and Homer et al. (2005) as a guide for producing quality studies so consumers easily can identify evidence-based practices. Finally, teacher preparation programs could consider peer tutoring to be a component of the curriculum that can provide preservice teachers with another research-based accommodation for students with disabilities.
IMPLICATIONS FOR PRACTICE
Four practices are identified as evidence-based practices in this review. First, and most important, peer tutoring in general is an evidence-based practice. This finding corresponds with the findings of several studies conducted in elementary settings (e.g., Delquadri et al., 1983; Greenwood et al., 1989; Greenwood et al., 1987; Johnson & Johnson, 1984; Maheady & Harper, 1987; Nelson et al., 1996) and of those studies conducted in secondary settings examined in the present review.

By using peer tutors, teachers can increase individualized instruction Individualized instruction is a method of instruction in which content, instructional materials, instructional media, and pace of learning are based upon the abilities and interests of each individual learner. for students with disabilities and increase students' engaged time (Greenwood et al., 1987).
In the current review, four peer-tutoring types are identified in the literature: reverse-role, heterogeneous, homogeneous, and cross-age. Only heterogeneous peer tutoring had enough evidence to support its use as an evidence-based practice. In studies in which heterogeneous peer tutoring was employed, the researchers recruited the peer tutors in two general ways: they identified them through a peer buddy course or the tutors were in the same class as the tutees.
Although peer tutoring--especially heterogeneous peer tutoring--is an effective practice, it appears that simply employing peer tutoring is not sufficient to ensure student learning. One of the strongest findings of this review is that training tutors prior to commencement of their peer-tutoring sessions is an important consideration. This seems obvious; however, it is not reported and is not discussed in all the studies reviewed. Teachers should train peer tutors to implement instructional methods (e.g., delivering praise, error corrections, monitoring tutee progress) while tutoring and, in future studies, researchers should report the training provided. In combination with tutor training, teachers should monitor tutors' behaviors while they are tutoring to correct and reinforce the behaviors that were taught to tutors during training.
Overall, peer tutoring is an effective method to teach students with mild disabilities the academic skills that are crucial for their success in secondary settings. Researchers implemented peer tutoring in a variety of settings and including students both with and without disabilities acting as tutors and tutees. Finally, the evidence presented in this review supports peer tutoring as an evidence-based practice.
