初中化学实验教学中学生证据意识的培养

The Cultivation of Students’Evidence Awareness in Chemistry Experiment Teaching in Junior High Schools

该研究基于初中化学实验教学中学生证据意识现状,旨在探讨如何利用化学实验教学培养学生的证据意识。研究发现:初中生对化学实验有浓厚的兴趣并具有一定的证据意识,能通过观察实验现象意识到证据的存在,但是意识不强,主要体现在对证据问题的提及较为表面,对于证据能否作为推出结论的依据,证据与结论间的因果关系建立较为模糊。由此提出,可通过优化实验手段、加强实验探究方案设计和养成实验反思习惯等策略来培养学生的证据意识。

This research has aimed at analyzing the current status of students’evidence awareness in junior high schools,and exploring how to use chemistry experiment to cultivate their evidence awareness.The research has found that junior high school students have a strong interest in chemistry experiments and have a certain amount of evidence awareness.They can realize the existence of evidence by observation,but such awareness is not strong enough,which is mainly reflected in the superficial reference to the evidence and the unclear understanding of whether the evidence can be used as the basis for the conclusion and how to establish the relationship between the evidence and the conclusion.Therefore,it is suggested that the cultivation can be strengthened by optimizing the experimental methods,strengthening the design of experimental inquiry schemes and developing the habits of experimental reflection.
