“It’s the teacher that makes the difference, not the classroom” - Michael Morpurgo The main purpose of this paper is to bring out an overview or feedback of initial trainee teachers on regular classroom teaching observation. The researcher acted as a mentor, observed the trainees, their behaviour and found their difficulties to face real classroom teaching through observation. Classroom observation is a formal and informal observation of teaching. A classroom observation is the purposeful examination of teaching and/or learning events through the systematic processes of data collection and analysis (Bailey, 2001). The present study has done in three phases- pre observation phase, observation phase and post observation phase. It is aimed to develop the confidence of trainees during classroom observation; to identify the difficulties during classroom observation. These objectives were followed by research questions. The researcher has followed observation method and collected data. The data were analysed through pie chart and graphs. The result of the study shows that initial trainee teachers gained experience through observation, since it is a critical process for teachers. Thus, this is an attempt for improving credibility of the classroom observation.
