| Summary: | 碩士 === 國立高雄師範大學 === 物理學系 === 95 === As the saying goes, “if you don’t know how to exercise, you don’t know nature.” Exercise is not only a key subject matter in the fields of science teaching and learning but also the main domain where research into natural science takes place. Therefore, the research on learners’ cognition patterns, levels, and the intensity to which they exercise plays a crucial role in the teaching and learning of kinematics.
This research uses semi-open written tests as the research tool, which in turn is designed in accordance with “statement of the proposition about kinematics” and “the analysis of the cognition types of kinematics.” Based on a theoretical model, the coding system of the respondents’ qualitative data is established to distinguish, organize and order the cognition patterns of the respondents (ninth graders from a junior-senior high school).
By using the software of SPSS, the usefulness, pertinence, and credibility of the research tool are assessed, and finally “a distribution of the respondents’ cognition patterns, levels, and intensity of exercise in kinematics” is generalized.
The research concludes that the cognition types of the students tested are as follows:
Type one: the students tested can not make a clear distinction between “objects” and “the character of the objects”.
Type two: The students tested have minimal knowledge about the idea of “vector”.
Type three: the students tested can not have an effective control over “the considerable factors” and “the inconsiderable factors”.
Type four: the students tested don’t have sufficient knowledge of “the original state of the objects”.
Type five: the students tested are prone to be influenced by their life experience toward “the rule of inertia”.
Type six: the students tested are convinced that seeing is believing toward “the idea of Free Fall”.
Type seven:students tested are not able to fully judge the coordinate values and slope of the longitudinal and lateral axis in the rectangular coordinate system.
The result of the study, when compared with previous related studies either in Taiwan or abroad, generates seven common points and six different points. (Consult Chapter 5)
This research offers suggestions on the teaching and learning of kinematics in two aspects. On the one hand, teachers should know clearly the common beliefs of students in order to conduct effective teaching which involves idea reformation. On the other hand, teachers can achieve efficient teaching through using more concise and scientific terms in their teaching materials.
Key words：kinematics, cognition patterns, alternative conceptions
