摘要
构建了建模能力的构成及表现框架,选取原电池为内容主题,基于学生电化学模型建构的2种路径,设计并实施了3种类型的促进学生建模能力发展的单元教学:基于分析型任务小开放度的建模活动、基于分析型任务大开放度的建模活动、基于设计型任务的建模活动促进学生建模能力发展。在理论预设的基础上,结合实践中学生的表现,描绘了学生建模能力水平的进阶情况。研究结果表明,分析型原电池建模教学与设计型原电池建模教学均能促进学生建模能力发展,但对建模能力不同维度的促进效果不同。通过教学实践发现了教学实施中的关键问题,总结了不同建模路径单元教学的核心策略。
The composition and expression framework of modeling ability is constructed,primary batteries are selected as the subject,and three types of unit teaching to promote the development of students'modeling ability are designed and implemented based on the two paths of students'electrochemical model construction:based on analytical tasks with semi-open in modeling activities,based on analytical tasks with full-open in modeling activities,and based on design-oriented tasks to promote the development of students'modeling ability.On the basis of the theoretical presupposition and the performance of the students in practice,the paper describes the advanced situation of the students'modeling ability.The results show that both the analytical and designoriented primary batteries modeling teaching can promote the development of students'modeling ability,but the effect on different dimensions of promoting modeling ability is different.This study finds the key problems in the teaching implementation and summarizes the core strategies of unit teaching in different modeling paths.
