A self-evaluation technique in improving teacher's professional development: The use of "realia" media and "wait time" strategies

Abstract

Personal teaching evaluation is an influential way to improve teacher's professional development and student achievement. The purpose of this study was to assess the teaching performance of the use of "realia" media and wait time strategy found in daily life to teach science for elementary school students. The anatomy of a blue crab was selected as the topic in this study. The teaching performances were analyzed qualitatively using the modification of Florida Teacher Performance Measurement system. Students' perceptions (n=32) of teacher teaching practice were used as extra information for this personal evaluation task. The result showed a positive response to class activity that has been designed using the realia media. Also, some students suggested that the wait time should have been implemented to show a sign of the willingness to give elaboration answer. Based on the analysis, although the teaching is less effective, it could be concluded that being confident (in relation to self-efficacy) was essential to support teaching activities such as showing enthusiasm, respecting the students, and other positive attitudes. Preparing a preserved specimen of a blue crab can be an alternative way to prevent fear and unpleasant scent in observing a blue crab for early grade school students.
