一般说来,初中学生的逻辑思维还没有发展到辨证逻辑思维阶段。但是,这并不意味着辨证逻辑思维的形式和方法不适合于初中化学教学,恰恰相反,恰当地把思维形式辩证法与初中化学概念教学相结合,对于分析研究教材,讲清讲透概念,进而培养学生抽象思维、判断推理能力都有一定的指导意义。兹提出以下点滴体会,供同志们参考。 一、讲授概念的灵活性的同时,必须强调概念的确定性。 1.由于概念所反映的客观事物是处在永恒的运动、变化之中,因此人的主观认识也必须随着客观世界的发展变化而不断扩大、加深,这
In general, the logical thinking of junior high school students has not yet developed into the dialectical logical thinking stage. However, this does not mean that the forms and methods of dialectical logic thinking are not suitable for junior middle school chemistry teaching. On the contrary, it properly combines the dialectic of thinking mode with the teaching of chemistry concepts in junior middle schools. For the analysis of research materials, the concepts are thoroughly explained. Cultivating students’ abstract thinking and judging reasoning ability have certain guiding significance. I hereby put forward some suggestions for the comrades. First, while teaching the concept of flexibility, we must emphasize the certainty of the concept. 1. Since the objective things reflected in the concept are in eternal movements and changes, human subjective understanding must also be constantly expanded and deepened with the development of the objective world.
