The purpose of this study was to develop an instrument for
evaluating the teaching competencies of junior high
school physics teachers in the physical science
laboratory.
There were six junior high school physical science teachers in
physics major participating in the study.
In the processes of developing the evaluation instrument ,the
researcher finished the domains、elements and indicators of the
necessary competencies in physical science laboratory teaching
based on related literatures、questionary、 the research
group discussion and examination by nine experts of
science education. After setting the items of the instrument
and finishing the pilot test, the study began the formal
evaluation.
The reliability of evaluation data located between 0.33~0.98,
and the stability of rating reliability were 0.82 and
0.78, thus the consistency and stability were acceptable.
The results of this study indicated the following
characteristics of instrument :
1. evaluators had to be trained on the usage with instrument,
2. evaluators should adopt high-inference evaluation method and
fill in "actual examples as evidence" as the bases for
evaluation, 3. researcher could offer five
implements to examine qualified teachers to meet the needs
of multiple varieties of schools, 4.
researcher provided a comprehensive user''''''''s manual for this
instrument to users convenience.
