Development and validation of University Teacher's Evaluation Scale.
Validity of research productivity as a measure of teaching effectiveness remains unclear. While some (Gavlick, 2006; Hong, Xuezhu, & Zhao, 2007; Stack, 2003) have found research productivity and teaching effectiveness to be positively correlated, while others (e.g., Feldman, 1993) have found measures of research to share little or no variance with measures of teaching. This leaves us with student evaluations, a rather complicated measure of teaching effectiveness. Proponents of student evaluations (Cashin, 1988, 1992; Cohen, 1981; d'Apollonia & Abrami, 1997; Dunkin & Barnes, 1986; Greenwald & Gilmore 1997) have argued that student ratings are generally both reliable and valid. Student's feedback and importance of assessment of teaching is now a vital component in the formal faculty performance appraisal systems of most universities (Clift, 1981; Lersch, & Greek, 2001; Trout, 2000).
A significant body of research related to this issue has been accumulated over the last many years. These studies focus on students' evaluation as accounted for by the interaction between students' and teachers' attitudes toward higher education (Hofman & Kremer, 1980), the nature of feedback to teachers, effects of feedback upon instruction, the efficiency of students' evaluation in improving instruction. Students' evaluations are used for two main purposes (Stack, 2003); summative (those used to evaluate teachers for rank, salary, and tenure purposes) and formative (those that diagnose in ways that allow teachers to improve their teaching (Khandelwal, 2009). The present research uses students' evaluations for formative purposes. Inarguably, students represent the most important stakeholders in any given classroom, and their satisfaction is not a trivial matter. The present study is an additional attempt to deal with this issue in the indigenous context of Pakistan.
Keeping in view the importance of teacher and teaching evaluation in the development of nation, present study aimed at the development of scale for the evaluation of their performance. The scale intends to identify components of effective teaching that would help teachers to play a more meaningful role in the sacred profession of teaching. The assessment of teachers has been done by gathering students' opinion, studying the educational product, analyzing teaching practices, and by taking opinions of colleagues as proposed by previous researches (Abrami & d' Apollonia, 1997; Bhantanger & Jain, 1994; Murray, Rushton, & Paunonen, 1990; Riaz, 2000). The student views of teaching effectiveness are important for evaluating teacher's effectiveness (Braskamp, & ory, 1994; Wheeler, Haertel, & Scriven, 1992) With the surge in public demand for accountability in higher education and the great concern for quality of university teaching, the practice of collecting student ratings of teaching has been widely adopted by universities all over the world as part of the quality assurance system (Kwan, 1999).
The key individual in the learning process is a teacher. Since his/her qualities and characteristics can highly affect the student's learning, there is an urgent need for the assessment of the qualities of teaching and teachers. In some universities of Pakistan, like many other under developed countries, the American model of academic credit system was adopted. This system gives considerable independence to teachers in determining what and how they can teach; and this is cost-effective system. But unfortunately the component of evaluation is missing from this system in most of these universities (Riaz, 2000). However, after nearly seven decades of research on the use of student evaluations of teaching effectiveness, it can safely be stated that the majority of researchers believe that student ratings are a valid, reliable, and worthwhile means of evaluating teaching (Koon & Murray, 1995; Marsh, 1990; Marsh & Dunkin, 1992, 1997; McKeachie, 1997; Murray et al., 1990; Seldin, 1999). Teaching evaluation seems to be an important topic. However, there are two important issues related to teaching effectiveness. The first issue is related to the accuracy of evaluations. Therefore, the major concern is related to the reliability and validity of the measuring instrument itself.
Results of several studies (i.e., Braskamp & Ory, 1994; Feldman, 1993; Marsh & Dunkin, 1992; Marsh, 2007; Murray, 1983; Perry, 1997, Seldin, 1999; Sproule, 2002; Wachtel, 1998) provide a general consensus about some apparent dimensions of teaching effectiveness. In Pakistan research on teacher's effectiveness has not been undertaken systematically (Riaz, 2000). The new developments in the field of education have created very different kind of needs, both on the part of students and teachers. Students' evaluations of teaching effectiveness (SETs) are variously collected to provide (a) diagnostic feedback to faculty that will be useful for the improvement of teaching; (b) a measure of teaching effectiveness to be used in personnel and administrative decision making; (c) information for students to use in the selection of courses and teachers; and (d) an outcome or a process description for research on teaching (Marsh & Roche, 1999; Radmacher & Martin, 2001). There is an essential need of a reliable and valid instrument of evaluation for teacher's effectiveness in institutions of Pakistan, where the education system is still not providing students the opportunity to give their feedback about teachers (Riaz, 2000).
Though, now the situation, especially on higher education level, is changing and many teachers desired to know the student's demands from their teaching, and how can they improve their performance in order to satisfy the needs of students and advance the overall quality of education system. For that purpose, both students and teachers need some reliable mode of teacher's assessment by the students. The primary purpose of developing the present rating scale is formative; that is, facilitating faculty growth, development, and self-improvement.
The study of gender differences between students and teachers related to their evaluation of teaching style effectiveness have also been planned in the present research. Though the previous researches have not shown very consistent differences between the gender of students in the evaluation of teaching style effectiveness (Marsh, 1984; Watchtel, 1998) but Tatro (1995) found that female students generally gave higher ratings than males, while Koushki and Kuhn (1982) found evidence supporting the reverse. However, in case of teacher's gender the previous researches revealed that gender (Freeman, 1994; Morris, Gorham, Stanley, & Huffman, 1996) has been investigated as important teacher characteristic related to effective teaching. As it is noted, that both genders have very different attitudes toward each other, especially in our culture, certain type of roles are associated to particular gender which are quite different to the roles assigned to the opposite gender (Hassan, 1994). The demands from a female teacher may be quite different, seen by each gender, as compared to male teacher. Keeping these cultural expectations in mind, it has been planned to see the differences in evaluation of teaching style regarding the gender of teachers. Researches show that the tendency of students to rate same-sex instructors slightly higher than opposite-sex instructors (Centra, 1993; Feldman, 1993). The present study also aimed at measuring perception of each gender student about teaching effectiveness of teachers of both genders.
Following above mentioned purposes of teaching effectiveness, it becomes very essential to assess these needs of teaching evaluation systematically and adopt proper strategies for teaching effectiveness. Therefore present study aimed at developing teacher's evaluation scale that may be applicable to all the universities of Pakistan with semester system, to measure the attitudes of students towards the teacher. This scale would be equally applicable to social and natural sciences, as it includes the items particularly suitable for the subject matter that both groups deal with. It is felt that even if the rating scales for measuring teacher's effectiveness are present in the educational institutions, however, these should be renewed after every two years, as the demands of students are changing very rapidly.
Though there is a reliable scale known as Peshawar University Teachers' Evaluation Scale (PUTRS) developed by Riaz (2000) but the need for development of a new scale is felt as there are differences in educational system for which both scales are developed. PUTRS is developed for evaluation of teachers in annual system and UTES is developed to be used in semester system. In annual system teachers have ample time to build rapport with students and cover course content while semester system provide the University teachers with the opportunity to comprehensively re-examine, redefine, and remodel curriculum as necessary to deliver breadth of information and depth of insight, as well as utility, in order to best meet the requirements of modern life and academic demands. Hence there emerged a need for separate teaching evaluation method for semester system as well. Moreover the differences in educational system between Pakistan and Western countries necessitate the development of an indigenous scale for semester system too (Riaz, 2000). The UTES is equally applicable for natural and social sciences as it included the items dealing with the subject matter of both sciences.
In the context of the aforementioned purposes, the major objectives of the present study were:
1. To develop an indigenous scale to measure the effectiveness of university teaching.
2. To establish the psychometric properties, that is, reliability and validity indices will be determined.
3. To explore the differences of male and female students in the evaluation of university teacher's effectiveness.
4. To explore the differences in the evaluation of male and female University teachers.
Study I: Development of the University Teacher's Evaluation Scale
The development of the scale was carried out in three phases. Study I intend to develop the University Teacher's Evaluation Scale, and comprised of three phases. Phase I aimed to generate item pool with the help of literature review, generating focussed group discussions with students and taking opinion of students with the help of open ended questionnaires. At the end of study I subject matter expert's opinion was taken for selection of final items. The selected items were factor analysed to determine the factorial structure of final scale. Details of each phase of Study I are as follows:
Phase I: Generation of item pool. The overall item pool was generated with the help of literature review, focus group discussions, and open ended questionnaires.
Literature review. The item pool for the scale was generated with the help of review of the existing literature. The identified categories through extensive literature review were (1) Command/ knowledge/Expertise; (2) Individual/Group communication/Interaction; (3) Clarity of presentation; (4) Breadth of coverage; (5) Teaching environment/Classroom management; (6) Fostering intellect/ Creativity; (7) Assignments/Readings/Handouts; (8) Fairness in grading/Examination; (9) Teaching styles; (10) Attitude toward students; (11) Personality factors; (12) Punctuality; (13) Conceptual clarity; (14) Organization/Balance/Planning; (15) Work load; (16) Teacher's involvement; (17) Ethical standards; and (18) Collaboration with parents (see for example, Abrami, 1985; Froyen & Iverson, 1999; Frey, Leonard, Beatty, & Shrock, 1981; Marsh & Thomas, 1992).
Focus groups. To generate items from identified categories, a series of focus group discussions were conducted with students of Quaid-i-Azam University, the size of each focus group comprised of 6 to 8 students. The total number of students participated in focus group discussions were 30 (16 men, 14 women). Their age ranged from 20-27 years (M = 23, SD = 7.25) from both natural (n =12) and social sciences (n = 18). Informed consent was taken from the participants selected through purposive sampling; and they were approached at University campuses. Special permission was acquired from the library staff to conduct focus group discussions in a peaceful room at library. On the basis of these three focus groups 342 items were generated. The number of items generated for each category were: (1) Command/knowledge/Expertise included 16 items; (2) Individual/ Group communication/Interaction included 43 items; (3) Clarity of presentation included 8 items; (4) Breadth of coverage included 23 items; (5) Teaching environment/Classroom management included 8 items; (6) Fostering intellect/Creativity included 14 items; (7) Assignments/Readings/Handouts included 13 items; (8) Fairness in grading/Examination included 23 items; (9) Teaching styles included 76 items; (10) Attitude toward students included 35 items: (11) Personality included 21 items; (12) Punctuality included 5 items; (13) Conceptual clarity included 15 items; (14) Organization/Balance/ Planning included 16 items; (15) Work load included 8 items; (16) Teacher's involvement included 11 items; (17) Ethical standards included 2 items; and (18) Collaboration with parents included 5 items.
Open ended questionnaires. To generate additional items, open-ended questionnaires were also administered on 20 students (10 men, 10 women) 5 men and 5 women from social sciences and 5 men and 5 women from natural sciences with age range of 20-27 years (M = 22, SD = 4.13) enrolled in M.Sc. and M.Phil Programs. The teacher's questionnaire was also given to 10 male and 10 female teachers; age range of the teachers was 35-50 years (M = 44, SD = 9.05). Students of Psychology (n = 5), International Relations (n = 3), and MBA (n = 2) participated from social sciences while from natural sciences, students of Biology (n = 4), Mathematics (n = 3), and Chemistry (n = 3) departments took part in the study. A total of 153 items were added to the existing categories. (1) Command/knowledge/Expertise (6 items); (2) Individual/group communication/Interaction (21 items); (3) Clarity of presentation (7 items); (4) Breadth of coverage (12 items); (5) Teaching environment/Classroom management (11 items); (6) Fostering intellect/Creativity (2 items); (7) Assignments/Readings/ Handouts (6 items); (8) Assignments/Fairness in grading/Examination (8 items); (9) Teaching styles (13 items); (10) Attitude toward students (16 items); (11) Personality factors (23 items); (12) Punctuality (5 items); (13) Conceptual clarity (5 items); (14) Organization/Balance/Planning (7 items); (15) Work load (4 items); (16) Teacher's involvement (3 items); (17) Ethical standards (3 items); and (18) Collaboration with parents (1 item). After adding the items from open-ended questionnaire, a total of 495 items were generated on each category identified. On the basis of these focus group discussions and open-ended questionnaire the already identified areas though literature reviews were further confirmed.
After extracting items from all these sources, these were transcribed in the form of statements and a questionnaire was prepared by combining all these statements. The items for overlapping and repetitive content were carefully checked and the redundant items were dropped; while remaining items were improved by rephrasing. Frequencies were also assigned to see which items were greatly emphasized and were common in all these different sources before deleting any repeated item. For the final confirmation of short listed 195 items, the list was given to the judges.
Phase II: Judges' opinion. The judges (6 men and 5 women) included M.Phil degree holders (n = 3), Ph.D Scholars (n = 4), and regular faculty members (n = 4) having an experience of at least five years in the teaching and completed their PhD with age range of 26 to 45 years (M = 35, SD 12.4). On the basis of the judges' opinion, overlapping and redundant items were eliminated and categories having the same type of items were merged. As a consequence, number of total categories reduced from 18 to 8 and the number of items in each category were also reclined. Thus the remaining categories included: (1) Command on the subject (11 item); (2) Communication skills (12 items); (3) Clarity of presentation, (13 items); (4) Breadth of coverage (9 items); (5) Teaching environment/Classroom management (11 items); (6) Fostering intellect/Creativity (7 items); (7) Assignments and Fairness in grading (10 items); and (8) Attitude toward students (12 items). The total number of items was reduced to 85 and all these categories were included in the University Teacher's Evaluation Scale.
Phase III: Factor analysis on the items of University Teacher's Evaluation Scale. In order to select the final items and get a factor situation of the scale, a factor analysis was carried out on independent sample.
Sample. The size of the sample was decided keeping in view the requirement of the sample size for factor analytic study. Kline (1986) has mentioned that a ratio of 3: 1 gave loadings essentially identical to those with a ratio of 10: 1. Therefore the sample consisted of 300 students of Masters Level including men (n = 150) and women (n = 150). The sample of male students of natural and social sciences (n = 150) and female students of natural sciences (n = 75) was taken from Quaid-i-Azam University Islamabad, and female students of social sciences (n = 75) were incorporated from Fatima Jinnah Women University, Rawalpindi. The age range of respondents was from 20-27 years (M = 23.0, SD = 1.40). Informed consent was taken from participants and they were ensured that their responses will be kept confidential and will be used only for research purposes.
Measure. The initial form of the University-Teacher's Evaluation comprising 85 items was used to collect the data. The scale consisted of five response categories reflecting the desirability of the quality to be present in effective university teacher. The five response categories ranged from do not agree (1), to strongly agree (5). The minimum possible score was 85 and maximum score could be 425. Demographic information was also obtained along with the questionnaire. The greater score on UTES indicates student's positive evaluation of teaching effectiveness and low score reflected student's negative rating of teaching effectiveness.
Firstly, as all the items of the scale were empirically determined, therefore it has sufficient content validity. To determine the dimensionality and construct validity of the scale developed, the 85 items were factor analyzed through Principal Component Factor Analysis. The value of Kaiser-Meyer-Olkin Measure of Sampling Adequacy .86 showed that data is meritorious for factor analysis. The large value of ([CHI-SQUARE] = 12526.69, p < .001) shows that correlation matrix is not an identity matrix and variables are positively correlated with each other.
Before the Barlett Test of Sphericity, item total correlation was also computed which showed all the items correlated significantly with each other ranging from .27 to .59 (p < .001). Following Guertin and Bailey (1970) while all the items are found highly correlated with each other and with the total, the Direct Oblimin Method of Principal Component factor analysis was applied. On the basis of .40 factor loading criteria of Factor Analysis, 49 items were retained. All these items are falling in one category, showing the unifactor structure of the scale.
Factor analysis yielded 49 final items and their corresponding loadings for the scale, which was named as University Teacher's Evaluation scale (UtEs). As evident from results, Factor 1 has an Eigen value of 18.17 which explains 18.9 percent of total variance. Other four extracted factors have the minimum acceptable Eigen values and explain very little amount of variance and hence the newly developed measure appeared to possess the quality of unidimensional scale measuring teaching effectiveness.
Alpha Reliability of UTES
After the final selection of 49 items of the scale UTES, the alpha reliability (.92) and split half reliability coefficients (.78) of the final items were significantly high, thereby indicating high internal consistency of the scale.
Study II: Determination of Psychometric Properties of University Teacher's Evaluation Scale and Gender Differences in Evaluation
Study II aimed in determining psychometric properties of University Teacher's Evaluation Scale, including reliability and validity of scale and checking for gender differences in evaluation of teachers by university students.
Sample. Independent sample consisted of 30 students (14 women and 16 men) of Masters in Business Administration, were taken from Iqra University, Islamabad with age range of 20 to 24 years (M = 22.0, SD = 1.40). The demographic information such as gender of the student, discipline, semester, and age was also obtained. The evaluation of male teacher and female teacher was measured separately from the same respondents. For evaluation, both male and female teachers (working at respective Department for at least 2 years) of same popularity were taken separately. For this purpose information was qualitatively obtained from both the management (including Director of the respective Department) and students through informal discussion and semi-structured interviews. The sample items included "to what extent the teacher presents the course in a well-organised manner?", "Does the teacher make sincere efforts to enhance student learning", and "to what extent the teacher has been confident in teaching the course?" Respondents were approached at their respective campuses. Moreover, informed consent was acquired from them, and was ensured that their responses will be kept confidential and will be used only for research purposes.
University Teacher's Evaluation Scale (UTES). The 49 items were retained in UTES after study I. UTES was found to be a single factor instrument measuring teaching effectiveness. Responses were obtained on a Likert type 5-point rating scale (strongly disagree = 1, disagree = 2, neutral = 3, agree = 4, strongly agree = 5) with minimum possible score of 49 and the maximum possible score was 245. The higher score on UTES indicates student's positive evaluation of teaching effectiveness and lower score signify student's negative evaluation of teaching effectiveness.
Peshawar University Teacher's Rating Scale (PUTRS). Peshawar University Teacher's Rating Scale (PUTRS) was developed by Riaz (2000), to evaluate student's perception of university teaching quality. Responses could be marked along Likert type 5-point rating scale (always = 5, mostly = 4, sometimes = 3, rarely = 2; never = 1) consisting of 25 items. The 25 affirmative statements refer to teacher's mastery of the subject, ability to stimulate intellectual curiosity, assignments/fairness in grading, student-teacher communication and teacher's attitude towards the students. The minimum score on PUTRS could be 25 whereas the maximum possible score was 125. Low scores on the test indicate poor quality of teaching whereas high scores demonstrate high quality of teaching. The scale can safely be regarded as a one factor test for the assessment of teaching quality at the university level. Riaz (2000) found .95 alpha reliability for PUTRS.
Reliability of the UTES
The two values of alpha for UTES and PUTRS for male and female teachers are computed. The Cronbach alpha coefficients on UTES for female teachers and male teachers are .93 and .89 respectively. Similarly, alpha values on PUTRS for female teacher is .98 and for male teacher is .90.
Test-retest Reliability was also calculated for estimating the temporal stability of the test. There was an interval of 15 days between the administration of the test and the retest. The two sets of scores obtained were used to calculate a coefficient of correlation indicating the test retest reliability of the scale. The correlation between the test and retest of UTES was significant at p < .01 (Women = .81, Men = .80).
Results indicated that in UTES the difference was non-significant between female and male students in the evaluation of male teacher; however, in PUTRS the difference was significant and the female students evaluated the male teacher more favorably as compared to male students.
Convergent validation was established by exploring the correlation between UTES and PUTRS. Results indicated that both scales have significant positive correlation with each other (r =.71, p < .001).
Universities are often assessed in terms of efficiency and effectiveness of its teaching faculty. Teachers have an important role in the socio economic development of their state in particular and the nation in general. The assessment of teacher's performance is not incorporated in the prevailing educational system of our country. As a result, educational standards are falling at an alarming rate. Every successful educational enterprise requires optimum utilization of human capabilities available to the system. Consequently, every such enterprise or activity needs periodic assessment and review. This has to be followed by search for better conceptual understanding, implementation strategies and practices. It is now well understood and appreciated that the role of teachers shall continually change in the 21st century for obvious reasons. While it will be necessary for the teachers and the teacher preparation systems to ensure regular acquisition of new skills and upgradation of existing skills, the assessment of the performance of teachers shall also remain an essential pre-condition for enhancing the efficacy of educational processes (Rajput, 1996). The present research aimed at development and validation of an indigenous scale for evaluation of effectiveness of University teaching.
The items for the scale were generated in Phase I. While developing the item pool for University Teacher's Evaluation Scale (UTES) a systematic process of empirical generation and careful selection of items was employed. The elaborated process for this purpose was carried out because of the emphasis that has been placed by several researchers and theorists on careful writing and selection of the items for development of an instrument (McKeachie, 1990; Rice, Stewart, & Hujber, 2000; Wylie, 1979). The findings of the study in phase III showed that 'Teachers Evaluation' is a uni-dimensional construct. The UTES constructed is found to be internally consistent and reliable scale. Thus the findings are consistent with the findings of previous research which identified teaching effectiveness as one factor construct (e.g., Marsh, 1980, 1981; Marsh & Bailey, 1993; Marsh & Hocevar, 1991; Marsh & Overall, 1981; Marsh & Roche, 1999; Marsh & Thomas, 1992; Riaz, 2000). After the final selection of 49 items of the UTES, reliability coefficients were determined, thereby demonstrating UTES as an internally consistent single factor scale.
Part II of the study pertains with the validation of the scale developed. The convergent validity of the scale was determined with an already developed reliable scale of teaching evaluation known as Peshawar University Teacher's Rating Scale (Riaz, 2000). The scale was administered on the students when they had not received their semester grading and was re-administered after they received the grading, but it does not affect their evaluation of teachers (e.g., see Tata, 1999).
However, the present research shows that the students' evaluations are reliable measure for teachers' evaluation, and there is consistency in student's ratings of both male and female teacher's evaluation in re-test. The correlation between the two scales came out to be quite satisfactory and assured the convergent validity of the scale. Though the PUTRS is a reliable scale but it is felt that teacher's evaluation scales should be developed or renewed after every two or three years as the demands and needs of students as well as teachers are changing very rapidly, so a proper assessment of these demands should be made.
The differences of male and female students in the evaluation of male and female teachers were investigated. The review of diverse literature reveals little consistent evidence of gender bias (Watchtel, 1998). For example, Tatro (1995) found that women gave higher ratings than male students, while present findings revealed that the difference is not significant, which is also supported by Koushki and Kuhn (1982). Results also indicated that in UTES there is nonsignificant difference in men and women in the evaluation of male and female teacher. However, in PUTRS the female students evaluated male teacher more favorably as compared to male students, hence; endorsing the findings of Feldman (1992, 1993). Existing research reviewed by Feldman (1993) on student ratings of male and female teachers in both the laboratory and the classroom settings. In his review of laboratory studies, Feldman (1992) reported that the majority of studies reviewed showed no difference in the global evaluations of male and female teachers. On the other hand, few studies in which differences are found, indicating male instructors receiving higher overall ratings than female teachers, in case when evaluated by female students.
Moreover, women faculty received higher ratings on questions addressing grading of students, and women students rated women faculty even higher than did male students. Researches (Basow, 1998; Seldin & Silberg, 1995) suggested that on questions of communication style and intellect (such as, speaks in an appropriate manner, has a wisdom to teach the subject), male faculty tended to be rated higher than their female counterparts by their students of both genders. However, the researches are not consistent in case of the category of 'command on the subject' (Dukes & Victoria, 1989). To receive good evaluations, male professors simply must demonstrate their competence and knowledge; that is, they need to fulfill their stereotypical gender role expectations. But female professors bear a double burden: they must fulfill both their gender role by being nurturing and warm, as well as their professional role by being competent and knowledgeable. For example, separate studies led by Bennett (1982), Statham, Richardson, and Cook (1991) found that female professors are judged more negatively than men if they are not more interested in and available to the students than male professors. But even when female professors are more available and more helpful, their overall ratings are no higher. In order to receive comparable ratings, female professors need to do more than their men counterparts. Thus, findings of no difference between male and female professors in overall ratings may mask the fact that different standards are being used to judge men and women faculty.
The present practice of scale development for teacher's evaluation aims at professional and educational improvement. If teacher effectiveness is assessed from time to time and incorporated into the system, it may motivate those who are brilliant, enthusiastic idealistic and professionally better equipped. An important function of this appraisal for many teachers is to improve staff communication and strengthen the channels of communication within the institution.
It is further hoped that the scale developed will provide administrators and teachers with extensive opportunities for training that underscore the complexity of the art of teaching. Expectantly, it will raise the level of discussion about good teaching, what it looks like and the connection between good teaching and student achievement.
Limitations and Suggestions
Although the UTES, on the basis of its psychometric characteristics, can be regarded as valid and reliable instrument to assess teaching effectiveness, there are few limitations. The findings of the present research provide a favorable evidence of and convergent validation of the UTES, but it should not be considered conclusive and the study is needed to be replicated. It is quite hard to achieve the construct validation in a single research as it is an ongoing and dynamic process of revising the definition and measurement of the construct. The convergent validity can also be further determined by using other scales developed for the evaluation of university teaching and by using scales of constructs which theoretically correlate with effective teaching. Moreover further studies can be conducted to determine the discriminant validity of UTES with related measures. Though Quaid-i-Azam University (QAU) is a national university with quota from each province representation, but still the size of sample for the research is not large enough to be representative of all the universities of Pakistan, because of time constraint and some other practical problems. There are many other variables like student's expectations concerning the instructors, student's belief, student's that the evaluations will be truly used for teaching improvement, emotional state of students at the time of evaluation, prior subject interest etc can influence their ratings.
Student's evaluation of teaching effectiveness can provide the diagnostic feedback to faculty about the effectiveness of their teaching that will be useful for the improvement of the teaching. A measure of teaching effectiveness can be used in administrative decision making. The information may further be used by students in the selection of courses and instructors. It also the measure of the quality of the course, to be used in course improvement and curriculum development. Apart from class room teaching student's opinions can also contain several questions pertaining to non class room aspects of the teacher's integrity, students' teacher relation, efforts that goes in preparation and updating of lecture material. Getting aware of student's perceptions and taking them positively, not only benefits a teacher and student, rather the whole system, the whole country. It is hoped that this scale will offer opportunities to new teachers and especially those having some difficulty in teaching, to improve by knowing their own limitations. The vast majority of those teachers who meet or exceed good standards of teaching but need support for their continued growth, will also be benefited by evaluations of their own teaching effectiveness.
