初中物理跨学科实践的教学设计——以手摇留声机为例

Instructional Design of Interdisciplinary Practice in Junior High School Physics—Taking the Hand-Cranked Phonograph as an Example

声音现象不易察觉,初二的学生刚接触物理学科,对事物的认识大多来自于感性经验。本文在“探究声音产生原因”的教学过程中,融入物理学史教育,利用自制手摇留声机丰富教学资源,让课堂充满人文气息,发挥物理学史的教育功能,帮助学生树立正确的科学观念,培养学生的物理核心素养。

The sound phenomenon is not easy to perceive. The students in the second grade of junior middle school have just come into contact with physics, and their understanding of things mostly comes from perceptual experience. In this paper, in the teaching process of “exploring the causes of sound”, the history of physics education is integrated, the self-made hand gramophone is used to enrich the teaching resources, so that the classroom is full of humanistic atmosphere, the educational function of the history of physics is brought into play, to help students establish a correct scientific concept, and to cultivate students’ core physical literacy.
