【摘要】：化学是以实验为基础的学科,实验部分在初中化学教学的内容中很重要,复习起来比较繁杂,而思维导图能将繁杂零散的知识点在大脑中更加直观化,网络化,对内容有一个整体的认识,把每个知识点与整个内容进行架构和对接,从宏观上把握,微观上掌握。因此本文基于思维导图设计了初中化学实验复习课的教学模式,并进行了实践研究。主要研究内容如下:首先,将相关文献资料进行分析整理,明确研究的背景、研究的目的及意义,并指出研究内容和方法,简要介绍思维导图,总结其在中学化学中的研究现状。然后,为使初中化学实验复习更加有针对性,效率更高,在整理实验内容的基础上,从实验试题的分值比重以及涉及的知识点出现次数两个方面对辽宁省沈阳市2014-2016年中考化学的实验试题进行统计与分析,讨论化学实验的重要性,把握中考实验试题的高频考查章节以作为本文中教学案例的选取进行具体阐述。最后,将初中化学实验复习与思维导图进行有机结合,设计了基于思维导图的初中化学实验复习课的教学模式,并将其应用于实际的教学中。为了考查其应用效果,选取两个平行班进行研究,实验班采用思维导图进行实验复习,对照班采用传统的教师讲授复习,定量比较分析学生的成绩,并根据访谈法,对学生主体性的变化情况进行研究,进而验证思维导图在初中化学实验复习中的应用效果。研究表明,化学实验内容在初中化学的教学中占有重要的地位,在中考化学试题中占较大比例,将思维导图应用于初中化学实验复习,可以提高学生的成绩,帮助学生形成高效的知识网络,也有利于提高其创新思维能力和学习兴趣。
[Abstract]:Chemistry is a subject based on experiments. The experimental part is very important in the chemistry teaching of junior high school. It is complicated to review, and the mind map can make the complicated and scattered knowledge points more intuitionistic and networked in the brain. There is an overall understanding of the content, each knowledge point and the whole content of the structure and docking, from the macro grasp, microcosmic grasp. Therefore, this paper based on the thinking map design of junior high school chemistry experiment review class teaching model, The main contents of the study are as follows: firstly, the relevant literature is analyzed and sorted out, the background, purpose and significance of the study are clarified, and the contents and methods of the research are pointed out, and the thinking map is briefly introduced. Then, in order to make the junior high school chemistry experiment review more pertinence and efficiency, on the basis of sorting out the content of the experiment, This paper makes statistics and analysis on the experiment questions in Shenyang City of Liaoning Province from the aspects of the proportion of the scores of the test questions and the number of knowledge points involved, and discusses the importance of the chemical experiments. Grasp the chapter of high frequency examination of the middle school test test question, as the selection of teaching cases in this paper for specific elaboration. Finally, the junior high school chemistry experiment review and thinking map organic combination, This paper designs the teaching model of chemistry experiment review course in junior middle school based on thinking map, and applies it to practical teaching. In order to test its application effect, two parallel classes are selected for research, and the experimental class adopts thinking map for experimental review. The control class used traditional teachers to teach review, quantitative analysis of students' achievements, and according to the interview method, the changes of students' subjectivity were studied. The results show that the content of chemical experiment plays an important role in the chemistry teaching of junior high school and occupies a large proportion in the chemistry test of junior high school. The application of thinking map to the review of chemistry experiment in junior high school can improve students' achievement, help students form efficient knowledge network, and improve their creative thinking ability and study interest.
