小学数学学习困难学生解题策略认知模拟及启示

Problem-solving Strategies Cognitive Simulation and Application of Elementary School Students with Mathematical Learning Disabilities

分析数学问题解题策略是提高小学数学学习困难学生解题能力的有效途径。近年来,随着信息技术和学习科学的发展,为深入分析学习困难学生解题策略提供了新方法。文章在已有学习困难研究的基础上,提出了解题策略认知模拟的方法,以小学数学"众数"问题为例,针对学习困难学生解题过程中存在的数据收集和统计策略等问题,依据小学数学问题解决认知模型,分析认知过程,编写认知程序,实现认知模拟。解题策略认知模拟有助于实现问题解决内部过程的可视化,对于设计与开发智能教学系统、构建智慧学习环境、提供有针对性的认知诊断和干预具有重要作用。

Analysis of mathematics problem-solving strategies is an effective way to improve problem-solving ability of mathematically disabled elementary students. Recently with the development of information technology and learning science, it provides a new method for elaborately analyzing problem-solving strategies of students with learning difficulties. Then, based on the previous research fruits, this paper proposed a cognitive simulation method for problem-solving strategies. Taking the problem of ＂mode＂ for example and aiming at the problems of data collection and statistical strategy in problem-solving process, the paper analyzed the cognitive process, wrote cognitive program and realized cognitive simulation according to the cognitive model of elementary school mathematical problem solving.It was helpful for visualization of the internal process of problem solving, design and development of intelligent teaching system, construction of smart learning environment, and provision of targeted cognitive diagnosis and intervention.
