基于批判性思维的小学科学实践活动教学设计

Instructional Design for Practical Science Activities in Primary Schools Based on Critical Thinking

小学科学教学强调在实践活动教学中培养学生的科学思维,提升学生解决实际问题的能力。如何基于问题展开实践活动的教学成为关注的重点。文章以“蚂蚁搬家蛇过道,大雨不久要来到”这一谚语为案例,在应用批判性思维二元问题分析法的基础上,形成实践活动教学设计的支架,并围绕“蚂蚁搬家预示着下雨吗?”这一问题全面展开实践活动,以确保课堂兼具学科性与科学性。

Primary school science teaching emphasizes the cultivation of students’scientific thinking and the enhancement of their ability to solve practical problems in the teaching of practical activities.How to develop the teaching of practical activities based on problems has become the focus of attention.The research takes the proverb“When ants move and snakes cross the road,heavy rain is sure to come tomorrow”as a case study,and form a scaffolding for the teaching design of practical activities based on the application of the binary problem analysis method of critical thinking,focusing on the question“Do ants move to foretell rain”.The question was used as the basis for the design of the practical activity,ensuring that the classroom was both disciplinary and scientific.
