基于6E教学模式的理工类STEM课程评价体系设计——以“水中兵器发射技术”课程为例

Design of the Evaluation System for Science and Engineering STEM Courses Basedon 6E Teaching and Learning Model:Taking the“Launching Technology of Underwater Weapons”Course as an Example

为在理工类STEM课程中构建合理的评估体系,以“水中兵器发射技术”课程为例,分析了STEM课程创设真实问题情境、跨学科融合和强调同伴协作三个主要特点;结合STEM课程的特点,阐述了形成性评价为主、总结性评价为辅的评价方式;发掘了课程内容中需重点评估的要素,并结合6E教学模式的各实施环节,确定了具体的评估方法,设计了过程文档。课程的教学实践为STEM课程评估体系设计提供了可行的方法。

To build a reasonable evaluation system for the Science,Technology,Engineering and Mathematics(STEM)courses of science and engineering type,this paper took the course of launching technology of underwater weapons as an example,and analyzed three features of the STEM curriculum including setting real situation,integrating disciplines,and emphasizing peer collaboration.Meanwhile,according to the features,this paper elaborated the evaluation method with the leading role of the formative assessment and a supportive role of the summative assessment,and found the important assessment element in the content of the curriculum.For each stage of 6E—Engage,Explore,Explain,Engineering,Enrich,Evaluate—teaching and learning model,we got detail evaluation methods and planned the process documentation.The teaching practice of this courses provided a possible practical route for the evaluation system design of STEM curriculum.
