High School Students Build Surveys Of Physical Concept Maps

The purpose of the students to study physics is to cultivate and improve the scientific literacy,and in this process, only by making them become the builders of knowledge can they improve their scientific literacy. Concept map, as a means of knowledge organization, can make students'cognitive structure explicit. Therefore, this paper will use the concept of high school students to construct the concept map to evaluate their cognitive structure, and study the formation process of their knowledge structure.In this paper, the comprehensive use of literature research, questionnaire survey, statistical analysis, case study. First of all, on the basis of consulting and collecting the domestic and foreign literature, we read through the relevant works and literature, providing the theoretical support and methodological guidance for the development of this paper. Then, a questionnaire survey was conducted to find out whether the students could use the concept map and accept the concept map.In the early days after the training of the students in the concept map, they were asked to construct the concept map in each new lesson to evaluate their mastery of the new course. When the completion of senior high school physics required a first and two chapter, let the students to"mechanical movement" as the theme of constructing concept map, the number of nodes, statistics student concept map connecting line number and effective connection number of language, and use the data collected for statistical analysis of related software. Select three different levels of the students as a case after the review of the construction of "mechanical movement" concept map,comparative analysis of their review before and after the concept map, draw the relevant conclusions. Finally, the corresponding teaching suggestions are given.Conclusion: the number of nodes, through the statistical differences of composition students painted the concept map connecting line number, the number of students more effective connection language, results showed that male and female students in the composition task on the performance of nearly the same number of nodes, school students in a high level of reserves to be more abundant, and the accuracy of node connection between nodes to performance is better, and the academic level of students with low language connection is simple, the number of nodes in the whole composition, many students do not write connectives. By the analysis of three cases found review after the students' concept had different degrees of perfection for academic students with lower levels of drawing the concept of quality is not high, although the number of nodes, the number of links also increased, but the understanding of knowledge still remain at the surface level, not Lenovo concept the connection that students do not have a deep understanding of the knowledge; the medium level students in the perfect map concept review after more significantly,in addition to the number of nodes, connection line number and effective connection number of language has greatly increased, the concept map integrity, accuracy and complexity of knowledge can be improved evidently; School Students with high level of concept map itself better, smaller changes later.Therefore, high school students to construct concept maps and phase differences, the concept map can be used as a highly sensitive tool for the assessment of students' physical knowledge structure change.
