高中生同分異構(gòu)體問(wèn)題解決差異性實(shí)證研究
[Abstract]:It is an important task of chemistry to cultivate students' ability to solve chemical problems. Organic chemistry is an important part of chemistry, and isomer knowledge is an important knowledge point of chemistry, which runs through the study of organic chemistry. Thus, it can be seen that it is important to explore the problem solving of students' isomer. Based on the theory of metacognition and problem-solving, this study adopts the combination of group test, typical interview and oral report, and takes the sophomore students as the research object. The students are tested by isomorphism test, metacognition level survey scale, isomorphism concept interview and isomer metacognition oral report. This paper also studies the students' metacognition level and isomorphism problem solving from the aspects of students' academic level and gender, and further studies the problem solving mechanism of students' metacognition affecting isomorphism. This paper mainly includes five parts: the first part: put forward the importance of this research topic, related problems and research status, clarify the research content and methods, research purpose and significance. The second part: through reading the relevant theoretical literature at home and abroad, and makes a detailed review of the research of guidance theory and related issues, to provide theoretical support for this study. The third part: the specific description of the process and methods of empirical research, including the compilation process of research tools, the basis for the selection of research objects and the research methods and procedures adopted. The fourth part: statistics and analysis of the scale and test, and combined with SPSS19.0 and EXCEL data analysis, draw conclusions, and targeted to provide suggestions for teaching. The main research and analysis are as follows: (1) to study the learning situation of students' isomorphism concept, and to attribute it through typical interviews. (2) to study the problem solving of students' isomorphism from two aspects of sex and academic level through the application test of isomorphism concept. (3) to investigate the students' metacognition level, from the academic level, This paper analyzes the influencing factors of students' metacognition level from two aspects of gender. (4) to explore the relationship between metacognition level and isomorphism problem solving, and to select different levels of students to make oral reports on isomorphism metacognition, and to analyze the psychological mechanism of students' problem-solving. Through the study, we mainly draw the following conclusions: (1) students' academic level affects their isomorphism problem solving, and students with high academic level have higher scores. (2) students' academic level affects their metacognition level, and students with high academic level have higher metacognition level. (3) students' metacognition level affects their isomorphism problem solving. Students with high metacognition level have high scores in isomorphism test, so teachers should pay attention to cultivating students' metacognition ability. Through the research, the following suggestions are put forward for teaching: (1) optimizing traditional teaching methods to help students better learn concepts. (2) cultivating students' metacognition ability and mobilizing students' active learning initiative. (3) changing the perspective of traditional diagnosis and paying attention to students' psychological mechanism of problem solving. (4) excavating the potential resources of excellent students to promote common progress with "excellent" and "poor". The last part: the summary and reflection of the study, including the summary of this study and the innovation and shortcomings of the study.
