Qualitative education plays an important role in technological advancement. Therefore, to prepare competent teachers, teaching technology has developed pre-service and in- service teacher education programmes. In order to make teacher education programme effective and to bring qualitative improvement, a need is felt to investigate the training of teaching skills at the micro level and teaching performance of student-teachers. The study envisages the effect of microteaching training in classrooms on teaching performance of student-teachers using pre and post experimental design. From the target population of student-teachers, a sample of 248 student-teachers enrolled during the academic year 2012-2013 at NKT National College of Education for Women, Chennai is chosen. From the statistical analysis, it is concluded that the post-training performance of teaching is significantly better than the pre-training performance of teaching of students both in B.Ed. and B.Ed. in Special Education. Hence, it is evident that microteaching training technique has a positive influence on the teaching performance of student-teachers. The gain scores of the teaching performance of student-teachers in B.Ed. and B.Ed. in Special Education courses did not differ significantly, revealing that the student-teachers in both the courses gained to the same extent because of their exposure to microteaching.
