The literature on the teaching of problem solving over the past twenty years promotes building students' metacognitive skills--planning, monitoring, and evaluating ones own thinking--as a means to improve their problem-solving skills (Costa, 1991; Perkins Per·kins , Frances 1882-1965.

Theoretical Basis Metacognition emerged as an important mental activity for solving problems when researchers began to study children's intelligence and problem solving. Early analyses of problem-solving performance revealed that good or expert problem solvers tended to plan, monitor, and evaluate their thinking during problem solving more often and more efficiently than did poor or novice problem solvers (Flavell, 1976). More recent studies have confirmed this finding for students at middle school, high school, and college levels (Bookman, 1993; Cai, 1994; Lucangeli, Coi, and Bosco This article is about the Irish children's TV character. For the Warner Brothers cartoon character, see Bosko. For other uses, see Bosco (disambiguation). Bosco is an Irish children's television programme produced during the late 1970s and early 1980s. , 1997). Flavell (1976) defined metacognition broadly as "one's knowledge concerning one's own cognitive processes Cognitive processes Thought processes (i.e., reasoning, perception, judgment, memory). Mentioned in: Psychosocial Disorders and products ... [and] the active monitoring and consequent con·se·quent adj. 1. a.

Mathematical task knowledge includes "one's beliefs about the subject of mathematics as well as beliefs about the nature of mathematical tasks" (p. 167). "Mathematical strategy knowledge naturally includes knowledge of algorithms The following is a list of the algorithms described in Wikipedia.

The focus of this study is almost exclusively on the mathematical strategy knowledge component of metacognitive knowledge. Research on students' mathematical strategy knowledge reveals that students at all levels--from elementary school elementary school: see school. through college--have difficulty planning, organizing, and evaluating their cognitive processes (Horak, 1990; Fortunato Fortunato walled up in a catacomb by the man he had wronged.

As a result of these findings, instruction in problem solving has tended to move away from teaching explicit strategies and heuristics alone and toward helping students develop metacognitive skills (Fernandez et al, 1994; Garofalo, 1986; Garofalo, 1987; Gray, 1991). Research on the effectiveness of teaching metacognitive skills in conjunction with mathematics problem solving, however, has tended to focus only on older students and special populations (Cardelle Elvar, 1995; Charles Charles, archduke of Austria Charles, 1771–1847, archduke of Austria; brother of Holy Roman Emperor Francis II.

Purposes The purposes of this study were to (1) explore mathematical problem-solving and metacognitive skills as developed by third-grade students prior to instruction in metacognition, and (2) examine the impact of year-long mathematics instruction that centers explicitly on the development of metacognition on the students' growth in metacognitive and problem-solving skills. Methodology The research methodology employed in this study can be classified as a year-long teaching experiment in which the primary researcher was the teacher of a class that focused on developing metacognitive skills. The teacher conducted the study in collaboration Working together on a project. See collaborative software. with a mathematics educator from a local university. This classroom-based research can help answer important instructional questions for teachers (Hiebert, 1999). It can focus on questions that are of concern to both teachers and researchers.

Subjects The subjects were the entire third-grade population, two classes of eight- and nine-year-olds, in a rural school in Kentucky Kentucky, state, United States Kentucky (kəntŭk`ē, kĭn–), one of the so-called border states of the S central United States. It is bordered by West Virginia and Virginia (E); Tennessee (S); the Mississippi R. . One class, designated as Metacognitive, was experimental; the other class, designated as Non-Metacognitive, represented a control group. Each class had 26 students at the beginning of the school year. Due to student withdrawals and incorrect taping during the data gathering, there were 21 students in the Metacognitive class and 23 students in the Non-Metacognitive class at the end of the school year. Teachers from the previous year used a stratified stratified /strat·i·fied/ (strat´i-fid) formed or arranged in layers. strat·i·fied adj.

Table 1 shows the characteristics of each class at the beginning of the year according to gender, age, achievement, and special needs. Teachers The two third-grade teachers varied greatly in background and experiences. The Metacognitive teacher, one of the authors, received her doctorate in teacher education and reading/language arts from a regional university. During her 12 years of teaching, she participated in several mathematics professional development programs, as well as mathematics portfolio training through the state department of education. Her students piloted mathematics portfolios for state assessment. The teacher of the Non-Metacognitive class completed a masters degree in education. During her 19 years of teaching, she received some mathematics training from the school district on a particular program. Based on analysis of the teacher plan books, both teachers scheduled 60 minutes a day for mathematics, used similar materials, and addressed the NCTM NCTM National Council of Teachers of Mathematics NCTM Nationally Certified Teacher of Music NCTM North Carolina Transportation Museum NCTM National Capital Trolley Museum NCTM Nationally Certified in Therapeutic Massage Standards. The teacher of the Metacognitive class used more manipulatives and emphasized problem solving and reasoning more often. The two teachers taught all core subjects in their respective classes.

In England there were formerly judges called Justices itinerant, who were sent with commissions into certain counties to try causes. teachers, however, taught art, music, physical education, and speech. The school also had a part time gifted/talented teacher who worked often with selected students in grades four and five, and occasionally with all students in both classes.

Earlier; before; prior to: prenatal. 2. and post-tasks respectively. The tasks, visual in nature, required students to organize their thinking, develop a plan, and obtain a solution. These visual tasks were chosen to ensure that specific mathematics content knowledge (e.g., fractions, polygons, graphs) did not affect performance on the task. To the best of our knowledge, the tasks were novel problems that were not used in classes prior to the study nor in either class during the study. The pre-task was administered to all students in October October: see month. ; the post-task was administered to all students in May. Table 2 presents the tasks as they were provided to students: Proctors were trained to present the tasks to each student individually. Prior to presenting the task, proctors asked students to "think aloud" while working on the task. The proctors presented tasks to students and listened to their comments. If students became quiet, they reminded the students to continue speaking with the use of specific verbal cues. At no time did proctors prompt students about problem solutions or respond to questions about the tasks. Each student was videotaped as he/she worked on the task. As a reader, picture an adult sitting next to a 9-year old student as she talks about the problem she is solving. The student is working on the post-task with five colored tiles and is explaining how the shape she has just made can be rotated rotated turned around; pivoted. rotated tibia see rotated tibia. on the desk. She says, "It can face this way or this way or this way." She continues to make different shapes and tell the adult how each can be rotated. She then turns to the paper and pencil to begin recording as she says, "I have found out 4 or 5 ways." After she has made each shape, she numbers them and counts out loud as she does. She pauses and says, "I found another one. That makes 6." She looks over her paper and says, "I don't don't 1. Contraction of do not. 2. Nonstandard Contraction of does not. n. A statement of what should not be done: a list of the dos and don'ts. have that one," and records the shape on her paper. She begins moving the tiles again. She says, "That makes seven," but she continues moving one tile tile, one of the ceramic products used in building, to which group brick and terra-cotta also belong. The term designates the finished baked clay—the material of a wide variety of units used in architecture and engineering, such as wall slabs or blocks, floor along the sides of the others. She says, "It (the tile) can come this way and that makes a new one." This example is a section of a thirty minute response from a single child in the metacognitive class. Instructional Methods The teacher of the Metacognitive class sought to create a culture of thinking (Tishman, Perkins, and Jay, 1995) throughout the day by using several different instructional strategies. These strategies encompassed a two-pronged Adj. 1. two-pronged - having two prongs divided - separated into parts or pieces; "opinions are divided" approach: (a) strategies that focused on raising student self-awareness self-awareness n.

The Non-Metacognitive teacher did not attempt to create such a culture and made no overt Public; open; manifest. The term overt is used in Criminal Law in reference to conduct that moves more directly toward the commission of an offense than do acts of planning and preparation that may ultimately lead to such conduct. OVERT. Open. attempts to develop her students' metacognitive skills. It is important to note, however, that both Metacognitive and Non-Metacognitive classes received six weekly lessons provided by the teacher of the gifted and talented program during September September: see month. and October. These lessons, a regular part of the gifted and talented program, presented Edward Edward killed his father at his mother’s instigation. [Br. Balladry: Edward in Benét, 302] See : Patricide de Bono's (1991) concept of thinking hats from Six Thinking Hats for Schools. Each of these lessons introduced a type of thinking mode with a picture of a colored hat, and students practiced that particular type of thinking during the half hour lesson. Metacognition was the subject of the last lesson. An analysis of lesson plans revealed that the thinking hat lessons were the only instruction on thinking skills in the Non-Metacognitive class. In the Megacognitive class, these six lessons represented the beginning of the students' exposure to instruction on metacognition. The Metacognitive teacher initiated a series of lessons on self-awareness in November November: see month. and maintained focus on them throughout the year. She used a program called Second Step (Committee for Children, 1992) to help students build better understanding of their emotional selves. During lessons, students learned the technique of mindmapping (Margulies, 1991) which encouraged them to explore ideas about themselves, their private hopes and dreams, and their understanding of mathematics.

During the last week of November, the Metacognitive teacher introduced a language of thinking (Tishman, Perkins, and Jay, 1995). She told the students that many kinds of thinking exist and that words can help them talk about specific kinds of thinking. The students and teacher generated a chart of thinking words like create, hypothesize hy·poth·e·size v. hy·poth·e·sized, hy·poth·e·siz·ing, hy·poth·e·siz·es v.tr. To assert as a hypothesis. v.intr. To form a hypothesis. , question, guess, opinion, evidence, and investigate. Blanks were left on the chart, and other words (e.g., plan, monitor, and evaluate) were added throughout the year as the class learned about them. In January January: see month. , the teacher began formal instruction in metacognition strategies. During mathematics lessons, she used modeling, explanations, group interactions, feedback and practice to help students learn how to plan, monitor, and evaluate their thinking. During problem-solving episodes, she encouraged students to take risks, to share failures and successes, and to find more than one way to approach a problem. Over the next several months, the teacher focused on four specific problem-solving strategies: look for a pattern, draw a picture, make a table, and guess and check. The teacher also developed metacognitive tools that encouraged students to: (a) plan before tackling a problem; (b) monitor while working on a problem; and (c) evaluate the success of solutions. These tools included planning sheets and checklists developed by the teacher. The teacher routinely asked students to share their monitoring processes with her while working on problems. Two pairs of raters were trained to analyze the videotapes of the pre- and post-tasks of each student. One pair scored the students' use of problem-solving; the other pair scored students' use of metacognitive strategies. This focus on both cognitive and metacognitive processes is consistent with Lester's (1985) suggestion that research on problem-solving should focus on both cognitive and metacognitive variables. Through viewing the videotapes, one set of raters scored students' problem-solving performance using two scoring guides, each respectively designed for the pre- and post-tasks. These guides can be found in Tables 3 and 4. The scoring guides were based on Pelve's (1957) analysis of problem-solving. Raters scored how well students demonstrated understanding of the problems, created strategies for solving the problem, and found correct solutions. Student scores could range from zero to eight, with three points maximum for understanding and correct solutions and two points maximum for using multiple strategies.

They used the Metacognition Category System (METACATS) (Goldberg, 1996) to determine planning, monitoring, and evaluating strategies. (See Table 5) One point was given each time a student demonstrated use of one of these metacognitive skills in solving the problems.

The correlation coefficient is calculated as: on samples of videotapes scored by both raters. The correlations ranged from .75 to .99, with only two correlations below .80. These reliability coefficients were deemed acceptable. To determine whether or not differences between classes existed prior to instruction, t-tests for independent means were applied to the problem solving and metacognition pre-task results of both classes. To determine the effects of metacognition instruction on problem-solving and metacognitive skills, t-tests for independent means were applied to the problem-solving and metacognition post-task results of both classes. Results How did student performance in problem-solving and metacognition compare across both classes prior to instruction in metacognitive skills? During the pre-task, student performance in problem-solving and use of metacognition statements were comparable for both classes.

Table 6 shows the comparison of problem-solving scores from each class during the pre-task: The table reveals two important results. First, the mean scores for both classes were relatively low. Means for all three components of problem solving for both classes were less than one (out of a possible three points for Understanding and Solutions and two points for Strategies). Furthermore, the means for overall problem-solving performance of both classes was less than two (out of a possible total score of eight). Most importantly Adv. 1. most importantly - above and beyond all other consideration; "above all, you must be independent" above all, most especially , the t-tests revealed that there were no significant differences (p < .05) between the two classes on any of the comparisons. The Metacognitive class scored slightly higher in understanding (mean difference = .37). The Non-Metacognitive class scored slightly higher in strategies (mean difference = .07) and in solutions (mean difference = .32). The means of the total scores were virtually the same. These results support the premise that the two classes were relatively equal with regard to problem-solving performance prior to instruction in metacognition. Table 7 provides comparison between the classes with regard to the number of metacognitive statements made by students during the pre-task. This table reveals similar results as those for problem solving. The mean scores for the six types of metacognitive skills indicated that students used very few metacognitive skills during the pre-task, especially with respect to Planning/Clarifying, Planning/Strategies, and Evaluate/Action. The means for these skills were virtually zero for both classes. The mean scores for Monitor/Review and Evaluate/Self were slightly higher, but each was still less than one. Clearly the students were not prone to use metacognitive skills during the pre-task because students in each class averaged slightly more than one metacognitive statement overall in completing the pre-task. Most importantly again, the t-tests revealed that there were no significant differences (p < .05) between the two classes on any comparisons of metacognitive skills. The Metacognitive class scored slightly higher in Monitor/Regulate (mean difference = .01), Evaluate/ Self (mean difference = .3), and Evaluate/Action (mean difference = .05). The Non-Metacognitive class scored slightly higher in Planning/Clarify (mean difference = .04), Planning/Strategize (mean difference = .08), and Monitor/Review (mean difference = .1). These results clearly support the premise that the two classes were relatively equal with regard to use of metacognitive skills prior to instruction in metacognition. How did instruction in metacognitive skills affect performance in problem solving? Given that students in both classes were comparable in the problem-solving performance, t-tests were conducted on the results of the post-tasks. Table 8 compares the two classes with respect to their problem-solving scores on the post-task. The analysis revealed two significant differences between the classes. Students in the Metacognitive class scored significantly higher (p<.05) than students in the Non-Metacognitive class on understanding (mean difference = .69) and overall problem-solving performance (mean difference = 1.02). Furthermore, Metacognitive students scored higher, although not significantly, than their counterparts in the Non-Metacognitive class on strategies (mean difference = .22) and on solutions (mean difference = .08). It is important to note that, on the pre-tasks, the Non-Metacognitive class scored higher than the Megacognitive class on solutions (mean difference = .28). How did instruction in metacognitive skills affect use of metacognitive skills in problem solving? The results of the analysis also revealed differences between the two classes in the use of metacognitive skills. Table 9 provides a summary of the use of metacognitive statements used by students in both classes during the post-task. Students in the Metacognive class used significantly (p < .05) more Monitor/Review (mean difference = 6.03) statements and total statements (mean difference = 5.79) than Non-Metacognitive students on the post task. In addition, Metacognitive students used more Planning/Strategize statements (mean difference = .10), Monitor/Regulate statements (mean difference = .21), and more Evaluate/Action statements (mean difference = .06) than Non-Metacognitive students, but the differences were not significant. Finally, Non-Metacognitive students used more Evaluate/Self statements (mean difference = .08) than the Metacognitive students. As revealed in Table 3, however, this mean difference represents a decrease in the difference on the pre-task (mean difference = .30). Students in the Metacognitive class made almost three times the number of metacognitive statements on the average than Non-Metacognitive students made on the post-task. Metacognitive students increased the average number of statements from the pre-task to post-task by 7.6, while the Non-Metacognitive students increased the average number of statements from the pre-task to post-task by about two. Clearly, instruction on metacognitive skills had an impact on the use of metacognition in problem solving, especially in the area of monitoring thinking. Discussion Instruction in metacognitive skills, as described in this study, increased the metacognitive skills used by third-grade students and thereby improved their performance in mathematical problem solving. In particular, students learned to monitor their thinking more often during problem-solving episodes as a result of the instruction. Furthermore, students receiving instruction in metacognitive skills increased their planning and evaluation skills, but not substantially. Problem-solving performance improved throughout the process; however, the most significant improvement occurred in the area of understanding. As a result of instruction in metacognition, students improved significantly in their attempts to understand the problem and slightly in their use of strategies and formulation formulation /for·mu·la·tion/ (for?mu-la´shun) the act or product of formulating. American Law Institute Formulation of solutions. The Metacognitive class's increase in monitoring during problem solving was not surprising. The activities provided by the Metacognitive teacher focused heavily on monitoring thinking and progress. Also, the Metacognitive teacher's use of cooperative groups would seem to contribute to this finding. The process of monitoring thinking becomes public as students solve problems in groups. Therefore, students weak in this skill have the opportunity to see how other students use monitoring to solve problems. In any event, it is clear from the analysis that these students learned this skill well. Interestingly, students in the NonMetacognitive class also increased their monitoring skills. Evidently maturity or experiences with problems seemed to help with this skill naturally, although purposeful pur·pose·ful adj. 1. Having a purpose; intentional: a purposeful musician. 2.

The most surprising result of the study was the almost total absence of planning by any student at any time. There was little evidence of planning in either the pre-task or post-task, despite a significant amount of instruction in planning in the Metacognitive class. At least two reasons for this finding are possible. First, and what we consider the most probable, is that students at this age are not inclined to engage in planning when posed with challenging problems. The Metacognitive teacher noted that even her best problem solvers tended to want to get "into" the problem immediately rather than step back and think about a plan. The impulsive im·pul·sive adj. 1.

Conjectures are ideas or notions founded on probabilities without any demonstration of their truth. Mascardus has defined conjecture: "rationable vestigium latentis veritatis, unde nascitur opinio sapientis;" or a slight degree of credence arising from evidence too weak or too is hard to verify (1) To prove the correctness of data. (2) In data entry operations, to compare the keystrokes of a second operator with the data entered by the first operator to ensure that the data were typed in accurately. See validate. elsewhere because little research in metacognition has focused on students at this age. Second, the tasks selected for the study simply might not have invoked a need to plan. Both tasks, visual in nature, are rather straightforward. Students simply can begin the problem by using trial and error to search for possibilities. Mathematics tasks that are more complex or have several components might require students to do more planning at the outset. The finding that evaluation skills were rarely used during problem solving might also be attributed to similar reasons. Although students tended to evaluate themselves occasionally, they rarely evaluated their own actions, despite instruction that focused on these skills. Again, it may be that students at this age simply are not willing to do much thinking once they arrive at a solution. During the Metacognitive class, students were often satisfied with simply finding a solution without concern whether or not it was the solution. Often students are conditioned in mathematics lessons in earlier years to focus on getting the answer. Once an answer is obtained, it is time to go to the next problem. Also as with planning, these two tasks may not have been challenging enough to stimulate a need for students to evaluate their actions. As with any research, this study raises some important questions about further research on teaching metacognitive skills. First, further research on the effects of age and development on a student's ability to learn metacognitive skills is warranted. Many educators promote the teaching of metacognitive skills to students in elementary school; yet, there is little research that focuses on the metacognitive skills of young children. This study raises the possibility that students at this age may simply not be ready or able to learn about planning and evaluating in problem solving. Perhaps third graders are in the early stages of developing the self awareness required to be knowledgeable of their thinking. Since, children at this age are just learning to be aware of their own thinking, they may not be yet able to successfully apply this self-awareness to mathematics problem solving. The location of the beginning age during childhood where instruction in some metacognitive strategies would be developmentally appropriate is a worthy pursuit. According to Flavell (1994), children of seven to eight years of age show a better understanding of introspection introspection /in·tro·spec·tion/ (in?trah-spek´shun) contemplation or observation of one's own thoughts and feelings; self-analysis.introspec´tive in·tro·spec·tion n. than do younger children. Perhaps children of eight to nine years of age not only improve their understanding and use of introspection, but also respond more to outside influences, such as classroom instruction. Further research should also focus on larger numbers of teachers and students. This study involved two teachers and 43 students in a small elementary school. Replication In database management, the ability to keep distributed databases synchronized by routinely copying the entire database or subsets of the database to other servers in the network. There are various replication methods. of the study with more teachers and students in a variety of schools would provide additional useful information. Using a variety of tasks, especially tasks outside mathematics, would provide further insight into the feasibility of teaching metacognitive skills in order to improve problem-solving performance in other areas. Finally, the Metacognition Category System (METACATS) was a useful tool to describe students' use of metacognitive skills during problem solving. It seemed to provide a structure to classify clas·si·fy tr.v. clas·si·fied, clas·si·fy·ing, clas·si·fies 1. To arrange or organize according to class or category. 2. To designate (a document, for example) as confidential, secret, or top secret. metacognitive skills in a clear and comprehensive way. The System is generic enough to be used in a variety of ways in research on metacognition. Closing Remarks Mathematical problem solving is a necessary skill for all students at all ages. Learning to become a problem solver is a life-long endeavor. This study centered on teaching metacognitive strategies to help young learners become good problem solvers. It revealed that instruction in metacognition may have a positive impact on student performance in problem solving. Some questions arise, however, with regard to the feasibility of spending time "Spending Time" is the first single released by Christian artist Stellar Kart. The lyrics describe the band members desire to spend "more time with God". "Sometimes it’s a real struggle to spend time with God. to develop metacognitive skills in young students. For this reason, further research in the metacognitive development of young students is certainly warranted.

TABLE 5 Metacognition Category System (METACATS)
PLAN/CLARIFY -- The statement demonstrates the child is preparing to do
something and is thinking about the task before tackling it. For this
category the child could be restating the problem or rereading the
problem. Example: I'm going to read this again.
PLAN/STRATEGIZE -- For this category the child could be planning a
strategy, attempting to identify a strategy, or announcing the
application of a particular problem solving strategy. Example: I gonna
try this. I think I'll make a pattern.
MONITOR/REVIEW -- This category of responses would demonstrate that the
child is engaged in a task and notices the success of her idea, or lack
of it, towards the task. She might review her work in order to avoid a
future mistake or find a current mistake. She might check her work for
errors or simply look over the work again (action noted by transcriber).
This category includes statements that would be categorized as planning,
if made before beginning the task, or evaluating, if made after
completing the task. Example: Now I found out four or five ways how to
do it (begins writing on paper to record ways).
MONITOR/SELF-REGULATE -- The child might regulate herself by adjusting
her activity. Generally, this category involves a change in behavior;
however, the child may say she is going to make a change after reviewing
her work. Example: I wasn't really counting.--First, I got four reds.
EVALUATE/SELF -- This category of responses would demonstrate that the
child is passing judgment on herself. Example: I can't think of anything
else.
EVALUATE/ACTION OR PRODUCT -- This category of responses would
Demonstrate that the child is passing judgment on actions or products.
Example: That's the very last one.
