-70 Since PBTE is still in the formative stages, much research is still necessary, especially in the area of evaluation. Topics that could be considered for research are: 1. Testing new means of measuring competence. 2. Designing instruments which truly evaluate competencies. 3. Increasing involvement of students in measuring change in teacher behavior. 4. Testing modules to measure change in teacher behavior. 5. Improving observation instruments. 6. Comparing training materials and courses for mastery of competency. 7. Replicating use of a high-and low-inference instrument in a study measuring change in teacher behavior. 8. Designing training materials other than modules for achieving competencies. 9. Improving techniques of observation a. Sampling size b. Number of observers c. Time factors This study will add evidence in practice to the theory of PBTE that training, in the form of modules, provides a way for teachers to build on their individual skills and interests. By making the objectives and evidence of
