学科领域知识在初中物理教学中的实践

Discipline Domain Knowledge Applied in Physics Teaching in Junior Middle School

本研究依据学科领域知识对传统的物理教学模式进行改进。在教学过程中,物理教师着眼于学生基础知识巩固、认知与元认知策略训练以及问题情境知识掌握。为了验证学科领域知识的教学价值,本研究开展教学实验,并自编《电学知识测验》评估实验组与控制组的教学效果。结果显示:1) 学科领域知识教学能够有效提高学生物理成绩;2) 学困生和中等生的陈述性知识与程序性知识有着显著提高,但学优生没有出现显著变化;3) 不同层次的学生条件性知识均有显著提高。

The study is to improve the traditional physics teaching mode based on the concept of domain knowledge. The teachers focus on the basic knowledge, cognitive and metacognitive strategies and condition knowledge. The study takes the experiments to assess the teaching results of the experimental group and control group in order to test the value of domain knowledge. The study gets some results. 1) The teaching based on the concept of domain knowledge is good for the teaching;2) The declarative knowledge and procedural knowledge of the students with learning difficulties and average students has improved significantly, but that of excellent students does not;3) The condition knowledge of all the students has improved significantly.
