精心设计演示实验促进科学思维发展--以“单摆”教学设计为例

Elaborating Design Demonstration Experiment and Promoting the Development of Scientific Thinking--Taking the Teaching Design of Simple Pendulum Experiments as an Example

以"单摆"为例,通过精心设计演示实验,创设学生深度学习的情境,通过问题逐步引导学生构建"单摆"模型,发展学生的模型建构能力.通过设计学生的学习活动,让学生展开系列实验设计和理论推导,发展学生的科学推理、科学论证、质疑创新等能力.

This article takes simple pendulum experiments for example.Aimed at cultivating students′model building abilities,the authors design elaborate demonstrations,create a situation of students′deep learning,and gradually guide students to build a single pendulum model by asking them questions.Through designing students′learning activities,the authors lead students to conduct a series of experiment designs and theoretical derivation to develop their abilities of scientific reasoning,scientific argumentation,questioning and innovation.
