初二学生光学建模能力水平的调查研究
Abstract This study takes grade 8 students of a middle school in Ruian city as the research object,and develops an optical second stage diagnosis questionnaire and an optical modeling ability questionnaire, used to detect the optical concepts as well as the modeling capability of eighth graders, with the former serving as the supplement. Research shows that junior two students of the school still exist many misconceptions after optical teaching ,and their modeling capability is generally low, especially in the model validation and the model application. Therefore, the researcher advises that in optical modeling teaching,a) teachers should pay full attention to the students' misconceptions, by establishing analogy models,which is similar to scientific conceptual models, guidingstudents to change misconceptions to scientific concepts. b) teachers should contact theory with practice, not only provide students with the common optical phenomenon, but also actively guide students to predict and explain with their theoretical knowledge. In addition, through the construction of concept maps, students can establish the link between knowledge points, forming a more systematic knowledge network. c) teachers should pay attention to the modeling of the subject, increase the modeling activities, in particular, highlight the model efficiency and the application , and gradually improve the modeling ability of the students.
