中学物理情境创设与实验教学改进策略——以“浮力”的教学为例

Secondary School Physics Scenario Creation and Experimental Teaching Improvement Strategies——Taking the Teaching of Buoyancy as an Example

浮力是初中物理教学中的重点内容之一,掌握浮力的相关知识要求学生具有较高的想象能力和抽象思维能力.我们将本节抽象内容通过自制教具以直观的方式呈现出来,不仅为学生创设直观形象的可视化物理情境,使教学过程清晰化,而且使用自制教具,让学生更加深入地理解浮力的产生原因,营造了创新氛围,激发了学生的创新意识.本文将以人教版初中物理八年级下册“浮力”这一节为例,进行教学创新详述.

Buoyancy is one of the key contents in the teaching of physics in junior high schools,and mastering the relevant knowledge of buoyancy requires students to have high imagination ability and abstract thinking ability.We present the abstract content of this section in an intuitive way through self-made teaching aids,not only creating visual physical situations with intuitive images for students,making the teaching process clear,but also using self-made teaching aids,so that students can more deeply understand the causes of buoyancy,create an innovative atmosphere,and stimulate students’sense of innovation.This article will take the section of the second volume of the eighth grade of junior high school physics“buoyancy”as an example to describe the teaching innovation in detail.
