初中生数学实验观的现状分析与教学建议

Current Situation and Teaching Proposal of Junior Middle School Mathematic Experiment

现代数学观的发展,已由静态的绝对主义的数学观向动态的拟经验主义的数学观转化,数学实验观则属于动态的数学观范畴。基于对417名初中生的问卷调查和访谈,结合课堂观察,了解数学实验观的5个梯级现状水平,发现初中生数学实验观念系统尚未真正形成。建议采取注重问题设计方案的实验性、重视教材中实验素材的使用性、强化问题解决实验的价值性等实践性举措,以促进初中生数学实验观的形成。

The development of outlook on modern mathematics has changed from static absolutism todynamic empiricism, while mathematic experimental outlook belongs to the category of dynamic mathematicoutlook. This paper conducts questionnaires and interviews with 417 junior middle school students, with theaid of classroom observation, gaining insight into the current five strata of mathematic experimental outlook.Findings show that the experimental outlook system has not really come into being. To promote the formationof such outlook, we should take practical measures such as emphasis on problem design, use of experimentalmaterial, and intensifying problem-solving experimental values.
