中学化学基本概念教学方法研究-毕业论文模板完整版.doc

xxxx大 学 （ 二 〇 一 六 年 四 月 摘 要 初中化学基本概念知识，是化学知识的重要组成部分，也是化学知识的关键部分，它是学好化学的基础，对于刚接触化学的初中学生来说，它枯燥，乏味，很难理解，并且记忆和应用。 所以，教师如何选取和运用合适的教学方法指导学生已显得尤为重要。 研究以吉林市X中学九年级四个班，共117名学生为被试。以学生的习题册和自编测试题为调查工具，通过文献法、调查法、实验法、三种研究方法进行研究，分析学生的习题和测试题的结果，对选取和运用的概念知识教学方法进行勘查。 基于认知心理学和意义建构主义学说，设计出适合概念教学的教学方法，并根据具体的概念的分类，选出适合具体概念的教学方法，应用到实际教学中。 经结果表明：实验班的成绩要明显好于对照班，说明教学方法的选择科学、合理有效，但学生的错题也反映出教学方法存在一些问题：不注重新旧概念间的联系、学生在习题上的概念意义建构不够好； 针对上述问题提出以下建议： 在教学过程中，要注重新旧知识的教学。 要注重在教学过程中，引导学生理解概念，应用概念 关键词：化学基本概念；教学方法；初中化学；实践研究 Abstract Chemical conceptual knowledge not only is an important part of chemistry knowledge，but also a key part of of chemistry knowledge it is the foundation of chemistry .For the junior middle school students who have just come into contact with chemistry, the chemical concepts are dull and difficult to understand, remember and apply. So how to select and use appropriate teaching methods to guide students is particularly important for teachers. This study takes 4 classes in the ninth grade 117 students of Jilin X junior school as subjects. Taking students’ exercises and tests as the survey tool, use three kinds of methods: literature method, survey method, experimental method. Analyze the results of exercises and tests, explore teaching method of conceptual knowledge selecting and using in teaching. Based on Cognitive Psychology and the Sense-Making Theory , design teaching method that is suitable for the chemistry teaching .Then,according to the classification of specific concepts, choose the teaching method that is suitable for the chemistry teaching，Fanally,apply it to the actual teaching. The results show that: experimental class is better than the control class ,that is to say,the method used in experimental class is accurate, reasonable and practical.But the wrong topics also reflects the problems of the method itself： first, the teacher does not pay attention to the link between the old and new
