【摘要】：21世纪以来,我们国家致力于基础教育改革,“学生进一步学习化学的基本观点和基本方法,形成科学的世界观。”成为化学基础教育课程改革的基本理念。模型方法作为科学方法的一种曾被誉为综合性最高的方法之一。然而,我们在化学教学中关于模型方法的教学研究甚少,如何更好的将模型方法与基础教育进行有效的结合,相互渗透至关重要。本文综述了国内外关于模型方法在基础教育中的教学情况,发现:国外关于模型方法的教学正在日渐成熟,我们国家在模型方法的教学主要集中在将模型方法做为一种教学策略帮助学生更好地进行概念辨析以及将思维模型作为一种解题方法直接传授于学生。从而导致学生并不理解模型方法的真正意义所在,更妄论自主建构模型。笔者通过问卷调查对81名学生化学学习中模型方法的认识与使用情况进行调查;并以这81位学生为模型建构教学模式的实践对象,分为实验班与对比班分别进行在高中有机化学教学中渗透模型方法的教学实践;同时在教学实践后对其进行相关的测试题答题情况进行分析研究,从而提出相关的教学建议。结果表明:1.学生对模型方法的认识还停留在物质模型阶段,对思想模型的认识并不深入;2.将思想模型渗透于有机化学教学可以更好的帮助学生自主建构思想模型。
[Abstract]:Since the 21st century, our country has been committed to the reform of basic education, "students further learn the basic views and methods of chemistry, and form a scientific world outlook." It has become the basic idea of the curriculum reform of chemical basic education. As one of the scientific methods, the model method has been regarded as one of the most comprehensive methods. However, there is little research on the teaching of model method in chemistry teaching. How to combine the model method and basic education effectively and permeate each other is very important. This paper summarizes the teaching situation of model method in basic education at home and abroad, and finds that the teaching of model method abroad is maturing day by day. The teaching of the model method in our country mainly focuses on using the model method as a teaching strategy to help the students to analyze the concept better and to teach the thinking model directly to the students as a problem-solving method. As a result, students do not understand the true meaning of the model method, and even more deluge on the independent construction of the model. The author investigated 81 students' cognition and use of model method in chemistry learning by questionnaire. Taking these 81 students as the practical object to construct the teaching model, it is divided into experimental class and contrast class, respectively, to carry on the teaching practice of infiltrating the model method into the organic chemistry teaching in senior high school. At the same time, after the teaching practice, the relevant test questions are analyzed and studied, so as to put forward the relevant teaching suggestions. The results show that: 1. The students' understanding of the model method is still in the material model stage, and the understanding of the thought model is not in-depth; 2. Permeating the thought model into the organic chemistry teaching can help the students to construct the thought model on their own.
