3D设计软件作为STEAM教育领域中的教学软件,可以有效培养学习者的空间思维、创新创造、批判性思维与解决问题等能力。目前,随着3D设计课程蓬勃发展,评价课程效果成为必然需求,但评价主要基于总结性和形成性评价,缺少基于学习过程行为数据驱动的评价。文章提出使用基于xAPI规范的3D设计软件数据采集机制与STEAM 3D教育学习者行为分析模型,首先针对3D设计软件对微观"点击流"和中观"活动流"数据进行编码,定义适合3D设计平台的动词和对象,获取学习者在3D设计平台中的全过程行为数据。并在此基础上,根据STEAM 3D教育学习者行为分析模型对小样本教学实践3D设计课程的学习过程数据进行分析,以期实现STEAM教育领域中数据驱动的学习评价,提高教与学效率。

As a teaching software in the field of STEAM education, 3D design software can effectively cultivate learners' abilities of spatial thinking, innovation, critical thinking and problem-solving. At present, with the vigorous development of 3D design course, evaluation of course effect becomes an inevitable demand, but evaluation is mainly based on summative and formative evaluation, and lack of data-driven evaluation based on learning process behavior. This paper proposes a 3D design software data collection mechanism based on xAPI specification and a STEAM 3D education learner behavior analysis model. Firstly, 3D design software encodes micro "click flow" and meso "activity flow" data, defining verbs and objects is suitable for 3D design platform, and obtains the whole process behavior data of learners in 3D design platform. On this basis, according to the behavior analysis model of learners in 3D education, this paper analyzes the learning process data of small sample teaching practice 3D design course, in order to realize the data-driven learning evaluation in the field of steam education, improve teaching and learning efficiency.
