大概念引领下的大单元教学设计及反思

Design of large unit teaching guided by big ideas and reflection

围绕草原鼠害发生发展防治创设大单元教学情境,实施以“任务-情境-活动”为主线贯穿的单元整体教学,依托情境设置和任务设计将多个课时的教学内容整合,将单元核心问题转化为进阶性的课时任务,在探究新知的过程中,呈现一个不断发现问题、解决问题的渐进式的学习过程,最终达成以大概念统摄的知识结构体系的建构,实现深度学习。

This article introduces a design of unit teaching that creates a large unit teaching scenario centering around the prevention of grassland rodent pests,and the main line of“task-scenario-activity”runs through the teaching of the unit.The teaching contents of multiple class hours are integrated by scenario setting and task design,and the core questions of the unit are transformed into staged class tasks.In the process of exploring new knowledge,a progressive learning process of constantly discovering and solving problems is presented,ultimately building a knowledge structure system guided by big ideas and realizing deep learning.
