| Chemistry is a subject based on experiment. The degree of mastery of the experiment affects the learning of chemistry, especially the grade three students who just began to learn chemistry in terms of influence is greater. This research is to SOLO classification evaluation theory as theoretical guidance, by means of open experiment questions to test on open grade students in solving chemistry experiment topic characteristic has carried on the thorough investigation and analysis of thinking. The characteristic has carried on the detailed investigation and analysis, and to find effective methods of cultivating students’ thinking, which provides reference for the implementation of quality education.In this study, a total of 123 students in grade forty-seventh year of high school in Guangzhou city of Guangdong province as the research object, using interviews and self-made test to analyzing that students’ thinking characteristics when they solved the problem of the chemical opening experiment. Research mainly divided into three parts:the first is consulted literature material and prepared test questions; the second is followed test in practice school and statistical analysis; finally, according to the diagnostic results of students with different levels of thinking, implemented developing strategies by the way of after-school tutoring. Study graded students in solving open experiment test question(in ninth grade, the second unit 《the air around us》for example) of thinking has the following features:1. On terrorize analysis case, students has strongly ability to solved it; about the experiment which determinate the content of oxygen’ s content in the air students also has higher degree master;2. On the experiment with Sulfur combustion on oxygen and prepared oxygen from hydrogen peroxide, students has high cognition level; about description to the phenomenon with experiment and the characteristics of experiment are more familiar;3. About the case with how the gas content increase or decrease effected the gas pressure and liquid flow, the students’ learning ability is not strong; the level of theinterdisciplinary manage knowledge little weak, abstract thinking is weak;4. Students’ thinking level of exploring the investigating subject are most weak,and the ability to designed of experiment also isn’t higher;5. Overall, the students’ thinking level are higher in this school, the majority of students’ thinking level in multivariate hierarchical structure and the associate structure, also has a part of students in the extension thinking level.According to the diagnostic results of students with different levels of thinking,implementation of targeted training on the basis of this strategy by way of after-school tutoring, combined with the SOLO taxonomy theory, to different levels of students in accordance with their aptitude. Through diagnosis, making a number of recommendations about teaching the second unit, then providing a reference for improving teaching. |
