“教师引导,学生自主”的真实问题课题研究——以解决教室电子屏反光课题为例

Study on the real problem of teacher guidance and student autonomy——Take classroom electronic screen reflection project solution as an example

以E-STEAM为标准,构建了完备的课题研究案例.以课堂中常见的电子显示屏反光问题为研究对象,通过3D打印、电路设计、照度测量和光路分析等手段复原真实反光场景,促使学生建立模型、提出方案和解决问题.该问题能够契合“光的偏振性”的拓展学习,在对该问题进行课题研究的过程中,教师能够引导学生理解、分析和解决问题,有助于提高学生的项目引导式思维能力.

With E-STEAM as the standard,a complete research case was constructed.The electronic screen reflection problem commonly seen in class was taken as the research object,and the real reflection scene was restored by means of 3D printing,circuit design,illumination measurement and optical path analysis,so as to encourage students to build models,propose scheme and solve problems.This project could fit the extended learning of polarization of light,and teachers could guide students to understand,analyze and solve problems in the process of the project research,which was conducive to improving students’project-oriented thinking ability.
