基于现代学习理论的递进式教学,充分考虑学生的现有发展水平和知识结构,以物理知识的内在逻辑为主线,以搭建“支架”帮助学生突破难点为抓手,按照学生的认知规律,引导学生渐次实现新知的建构和能力的不断提升.本文以高中物理选修3-1“电源和电流”一节的教学为例,对递进式教学进行了较为深入、全面的探析. Progressive teaching based on modern learning theory, give full consideration to the students' current level of development and knowledge structure, the internal logic of physical knowledge as the main line, to build “bracket ” to help students break through the difficulties as the starting point, according to the students recognize To guide the students to gradually realize the construction and ability of the new knowledge continues to improve.This article takes the teaching of high school physics elective 3-1 “power and current ” as an example, conducted a more in-depth and comprehensive Analysis
