Abstract

The purpose of this study is to develop educational programs that can improve the level of meta-modeling knowledge of chemistry teachers and to find out the educational effects. For this study, we reconstruct the level of meta-modeling knowledge based by ‘model multiplicity’ which is related to model, and ‘model changeavility’ and ‘evaluation of models’ which is related th the modeling. Educational program is consisted of 15 sessions and its based on reconstructed meta-modeling knolede level and GEM cycle. Also three states of materials were selected as materials for the Non-contextual situation of chemical education. The results obtained through this study are as follows. The level of chemistry teachers about ‘model multiplicity’, ‘model changeavility’ and ‘evaluation of models’ were all 0 or 1 at beginning the program, but after the program, the lever gradually improved. In particular, in terms of model multiplicity and model changeavility, all teachers improved to level 3 at the end of the educational program. However, about half of the teachers’ evaluation of models stayed at the level 2 at the end of the educational program. This is because level 2 of ‘evaluation of models’ stops at the sophistication of the model, but level 3 must be able to predict the phenomenon with the model. Therefore, it can be confirmed that it is difficult for many chemistry teachers to switch to activities that predict phenomena with models. Accordingly, it is necessary to continuously conduct research on chemical teachers to develop teaching capabilities for model evaluation.
