本文结合我校“探究数学”教学思想模式,引导学生通过大胆猜想、动手实验、验证应用等环节,明确本质都是将不规则物体转化为规则物体计算体积。教材分析:本节课是在学生已经掌握了长方体和正方体的特征、体积、容积以及相关单位的基础上呈现的。本节课旨在通过实验操作、小组合作与探究活动,培养学生的探究意识,加深对体积概念的理解,掌握用“排水法”求不规则物体的体积。设计理念:《新课标》倡导动手实践、自主探索、合作
This paper combines my school “inquiry mathematics ” teaching mode to guide students through bold conjecture, hands-on experiment, verification application and other aspects, the clear essence is to convert irregular objects into regular objects to calculate the volume. Teaching material analysis: This lesson is based on the students have mastered the characteristics of cuboids and cubes, volume, volume and related units based on the presentation. The purpose of this lesson is to develop students’ awareness of inquiry, deepen their understanding of the concept of volume, and grasp the volume of irregular objects by using the “drainage method” through experimental operations, group cooperation and inquiry activities. Design Concept: “New Curriculum” advocate hands-on practice, independent exploration and cooperation
