基于Blackboard平台的热学混合式学习投入影响因素研究

RESEARCH ON THE CURRENT STATUS AND INFLUENCING FACTORS OF THE THERMAL BLENDED LEARNING ENGAGEMENT BASED ON BLACKBOARD PLATFORM

混合式学习投入是衡量学生混合式学习质量的关键因素。研究以利用Blackboard平台开展的热学课程为例,基于国际经典学习投入测量量表,构建热学混合式学习投入及影响因素的结构方程模型。采用问卷调查收集数据,分析了教师层面、学生层面及媒体层面对学生热学混合式学习投入的影响及作用机制。研究表明,学生层面对热学混合式学习各个阶段的学习投入均存在显著的正向影响;媒体层面在教师与学生层面之间存在中介效应,教师通过Blackboard平台的交互等功能影响学生个体层面,进而间接影响学生的热学混合式学习投入水平。在此基础上,为在特定情境下开展混合式学习提供参考与建议。

Blended learning engagement is the key factor to measure the quality of blended learning. Taking the thermal courses conducted using Blackboard platform as an example, the study builds a structural equation model of the combined thermal learning engagement and its influencing factors based on the international classical learning engagement scale. A question-naire was used to collect data and to analyze the influence and mechanisms of action at teacher level, student level and media level on students􀆳 engagement with blended learning in hot learning. The study concludes that there is a significant positive influence of the student level on the engagement in all stages of blended learning in hot learning, and that there is a media-ting effect of the media level between the instructor and the student level, with the instructor influencing the individual student level through the interactive features of the Blackboard plat-form, which in turn indirectly influences the level of student engagement in blended learning in hot learning. On this basis, it provides reference and suggestions for development of blen-ded learning in specific situations.
