Abstract

This study analyzed correlations between scientific model assessments and consistency appearing in the process of pre-service elementary school teachers’ developing a food web and ecological pyramid model. As research subjects, 15 students in the third school year of education graduate school, who were taking classes of science teaching material research and teaching methods, were selected and divided into 5 groups, each of three persons. They were made to develop a food web and ecological pyramid model for about a month. Then, their reports on results, models completed, inquiry diaries and PPT presentations were all used as analysis data. The analysis results were as follows; Firstly, when analyzing consistency in the process of developing such a model, this study found consistency in two different perspectives from three groups and one perspective from two other groups. Secondly, when analyzing causes leading consistency to break-off, this study found one cause in the phase of setting learning goals, two causes in the phase of actual survey, one cause in the phase of analyzing textbooks and three causes in the phase of developing a model. Thirdly, this study discovered that as a group had higher frequency of consistency, it received higher scores from the scientific model assessment.
