| Summary: | 碩士 === 國立彰化師範大學 === 物理學系 === 107 === Understanding of model has been emphasized in science education. Because models play a bridge between abstract scientific theory and real phenomena. Meanwhile, models have the functions of description, prediction and interpretation. Because Textbooks contain a large number of scientific models, textbooks are the most common learning medium when students are learning science and teacher are planning curriculum. Therefore, it is important to understand how the textbooks represent the scientific models.
The research includes two parts. First, researcher adopted the content analysis to analyze the physics models in the junior high school textbooks which includes optical, mechanics, electromagnetic, thermal, and wave units. Second, discussed the physics models from the perspective of aspect of model. The results of the study are summarized as follows:
(I) The content of the physic model in textbooks mainly focus on how do scientific theory explain the real phenomenon and the difference between the scientific theory and real phenomenon. In conclusion, current textbooks focus on linking the abstract theory with the real phenomenon.
(II) From the perspective of understanding of model, the content of the mechanics unit is the most comprehensive among the five units. Because the mechanics unit not only use scientific theory to explain real phenomenon but also includes the development history of mechanics, the process of revising model and several consensus models may co-exist with respect to the same target
This study contributes to analysis of textbook by finding out the imperfections of the textbooks. Meanwhile, the researcher also provided the writing suggestions to textbook writers. What is more, when teachers adopt textbooks to design curriculum, they can adopt the result of this research to understand the differences between high school and junior high school textbooks in advance.
