【摘要】：初中化学变式教学的基本思路是采用不同的知识体系和教学方法,对相关化学基本概念和普遍规律、初中化学实验、教法与学法等方面进行多层次、多角度、不同背景和情形下的变式设计,有目的的指引学生透过“变”的现象看清“不变”的本质,从“不变”的本质中寻找规律,有利于改善他们的独立思考品质,提高其应对能力,激发他们学习化学学科的兴趣,树立探索精神和创新意识,实现新课程标准所要求的培养目标。通过化学变式的相关训练,增强学生对概念掌握和理解,知识体系得到巩固,应用能力得以拓展,思维更灵活,思路更清晰。任课教师通过化学变式方法创设问题情境,深入剖析教材,不断深化教学改革,为初中化学教学研究打下坚实的基础,为学生创设自主学习和发展的空间;在解决问题过程中,任课教师通过变换题设的外在条件、特征或结论激活学生发散思维,多维度探寻问题的解决途径,发挥学生主观创造性,激发学习兴趣和动机,培养勇于探索、敢于挑战的精神。论文针对目前农村初中化学教学存在的若干问题,通过调查问卷理清了目前农村初中化学的“教”与“学”的现状,根据“变式”教育相关理论对存在的问题进行深入分析,并针对问题设计了一系列的“变式”案例,以期对农村初中化学教学改革提供一定的参考。
[Abstract]:The basic idea of chemistry variant teaching in junior high school is to adopt different knowledge system and teaching method, to carry on the multi-level and multi-angle to the related chemistry basic concept and the universal law, the junior middle school chemistry experiment, the teaching method and the study method and so on. The variant design under different background and situation can guide students to see the essence of "invariance" through the phenomenon of "change" and find the law from the essence of "invariance", which is helpful to improve their independent thinking quality. Improve their coping ability, stimulate their interest in the study of chemistry, establish the spirit of exploration and innovative awareness, achieve the new curriculum standards required by the training objectives. Through the chemical variant of the relevant training. Strengthen the students to grasp and understand the concept, the knowledge system has been consolidated, the application ability can be expanded, the thinking is more flexible, the thinking is clearer. The teacher creates the problem situation through the chemical variation method, deeply analyzes the teaching material. Deepening teaching reform, laying a solid foundation for chemistry teaching research in junior high school, creating space for students to learn and develop independently; In the process of problem solving, teachers change the external conditions, characteristics or conclusions to activate the students' divergent thinking, explore the solution of the problem in many dimensions, and give full play to the students' subjective creativity. Stimulate learning interest and motivation, cultivate the courage to explore, dare to challenge the spirit. The paper aimed at the current rural junior high school chemistry teaching problems. Through the questionnaire to clarify the current rural junior high school chemistry "teaching" and "learning" status, according to the "variant" education related theory to carry out in-depth analysis of the existing problems. A series of "variant" cases are designed in order to provide some reference for the reform of chemistry teaching in rural junior middle schools.
