【摘要】：2008年江苏省高考方案实施以来,化学学科受到了较大冲击,学科地位下降,课时大幅减少,学生重视程度降低。这样的不利条件下,如果我们继续按常规的复习模式,即基础知识梳理——重点难点归纳——习题巩固提升开展高三化学教学活动,不仅课时紧张,也无法调动学生学习化学的兴趣,造成学生化学科学素养、学习能力的低下。同时,“以实验为基础”是化学学科基本且有效的手段,高三化学教学也不应摒弃。因此,笔者提出了以实验为基础,在高三化学教学中开展主题式教学的构想及实施途径。本论文采用文献研究法、课堂观察法、测试法、问卷调查法等研究方法。从专家学者的相关著作中查找开展主题式教学的理论依据、主题式教学的特征、流程及意义,并结合自身体会、感悟、实践,对高三化学教学进行学情分析,在理论与现状分析的基础上,从教学目标、教学内容、教学形式、教学方法、教学评价等方面阐述教学原则,从生产、生活、社会等角度进行教学分类,从教学实践出发设计教学的一般流程。在此基础上笔者结合本人在高三化学复习中实施的三个案例,通过课堂观察评价学生课堂参与度、通过对实施主题式教学小组进行学习前后的纸笔测试分析以及与按常规教学方式学习的小组进行纸笔测试成绩比较,分析实施基于实验的高三化学主题式教学的高效、有效性。研究发现,高三化学教学中以实验为基础,开展主题式教学是可行且有必要的。高三学生在已有知识的基础上,对运用实验整合复习化学有很高的期待值,对运用已有知识解决生产性、生活性、社会性等各方面的化学问题有极高的探究热情。在高三化学复习中采用以实验为基础的主题式复习,不仅使高三化学教学有趣味、有内容、有意义,同时也让学生通过实践感知化学探究的一般路径,提高化学科学素养、树立正确人生观、价值观、世界观。
[Abstract]:Since the implementation of the college entrance examination program in Jiangsu Province in 2008, the subject of chemistry has been greatly impacted, the status of the subject has declined, the class hours have been greatly reduced, and the degree of students' attention has been reduced.Under such unfavourable conditions, if we continue to follow the conventional review model, that is, combing basic knowledge, summarizing key and difficult problems, consolidating and promoting chemistry teaching activities in Senior three, we will not only be tense in class hours,It can not arouse students' interest in chemistry, resulting in students' chemistry scientific literacy and low learning ability.At the same time, "based on experiment" is the basic and effective means of chemistry, and chemistry teaching should not be abandoned.Therefore, based on experiments, the author puts forward the conception and implementation of thematic teaching in senior high school chemistry teaching.This paper adopts literature research, classroom observation, test, questionnaire and other research methods.From the relevant works of experts and scholars, the theoretical basis for developing themed teaching, the characteristics, process and significance of themed teaching are found, and combined with their own experience, perception and practice, the study situation of chemistry teaching in Senior three is analyzed.On the basis of the analysis of theory and present situation, this paper expounds the teaching principles from the aspects of teaching objectives, teaching contents, teaching forms, teaching methods and teaching evaluation, and classifies teaching from the angles of production, life, society, etc.Design the general process of teaching from teaching practice.On this basis, the author combines the three cases that I have implemented in the chemistry review of Senior three, and evaluates the students' participation in the classroom through classroom observation.By analyzing the paper and pen tests before and after the implementation of the thematic teaching group and comparing the results of the paper and pen tests with those of the conventional teaching group, the paper analyzes the efficiency and effectiveness of implementing the experiment-based thematic teaching of chemistry in senior high school.It is found that it is feasible and necessary to carry out thematic teaching on the basis of experiment in senior three chemistry teaching.On the basis of the existing knowledge, the senior students have a high expectation on the application of experimental integration to review chemistry, and a high enthusiasm for using the existing knowledge to solve the chemical problems of productive, living, social and other aspects.The theme review based on experiments in senior three chemistry review not only makes chemistry teaching interesting, content and meaningful, but also enables students to improve their chemistry literacy through the practice of perceiving the general path of chemistry inquiry.Establish a correct outlook on life, values, and world view.
