Abstract:
The objective of this study were (1) to develop a system to evaluate practice teaching students based on 360 degree feedback (2) to pilot test the system to evaluate practice teaching students based on 360 degree feedback, and (3) to audit the quality of a system to evaluate practice teaching students based on 360 degree feedback and to compare generalizability coefficients in different evaluated situations. The samples under phase (to develop a system) consisted 20 supervisors, 10 student teachers, 10 Thai-teachers, 5 specialists in 360 degree feedback and 5 specialists in measurement and evaluation. In phase II (to pilot test the system) and phase III (to audit the quality of a system) there were 63 student teachers, 239 supervisors, and 630 students. The instruments used in this study were interview forms, questionnaires, records and other relevant forms. The statistics used for quantitative data analysis were descriptive statistics by SPSS, second order factor analysis by using LISREL program and generalizability coefficients by using GENOVA program for window, where as content analysis was used for qualitative data analysis. The research results revealed that a suitable and practical system to evaluate practice teaching students based on 360 degree feedback that consisted of 4 basic dimensions : inputs, process, outputs, and feedback. The inputs dimension consisted of appraisal of objective, practice teaching indicators and criteria, appraisal instruments, appraiser and appraisees. The process dimension consisted of practice teaching appraisal planning, constructing and developing the appraisal instruments, collecting the practice teaching data, analysis and evaluation practice teaching by comparison with the appraisal criteria. The outputs dimension consisted of recording result of practice teaching, and the feedback dimension consisted of feedback for all stakeholders. The results from system implementation showed that the components of the system had propriety at high level. Moreover, most of stakeholders indicated that the system met the evaluation standards composed of utility composed of utility standard, feasibility standard, propriety standard, and accuracy standard at high level. Furthermore, system users and all stakeholders were satisfied with it. The generalizability coefficient for formative evaluation for 4 times, 4 sources of evaluators and 2 evaluator for each sources was 0.7082 and the generalizability coefficient for summative evaluation for 2 times, 2 sources of evaluators and 2 evaluator for each sources was 0.6123.
