THINKING ABOUT SIMPLE MACHINES: MODEL-BASED REASONING IN DESIGN CONTEXTS

9355850莱勒这个项目是研究学生如何发展基于模型的推理。研究的背景是学生在基于乐高标识的背景下规划和构建发明。然而，主要的研究将是诊断学生对功能简单机器的理解，了解关于简单机器的知识是如何在各种教学环境中发展起来的。将包括教师开发的基于设计的教学单元，以促进基于模型的推理和对学生在设计环境中发明和使用的概念的调查。将开发一种计算机辅助设计和仿真工具。***

9355850 Lehrer This project is to study how students develop model-based reasoning. The context is to study students in the context planning and constructing inventions based on LEGO LOGO. However, the main study will be to diagnose student understanding of functional simple machines, understand how knowledge about simple machines developed in various pedagogical contexts. Included will be teacher-developed design-based instructional units to foster model-based reasoning and investigation of the notions that students invent and use in design contexts. A computer assisted design and simulation tool will be developed. ***
