本研究基于大学物理混合式协作学习实践，采用内容分析法对混合式协作学习的交互内容进行分析，按照布鲁姆 的学习目标分类法建立编码框架，确定交互内容的质量，并将交互质量和交互数量与学习者的学习成绩进行线性相关分析.研 究发现: 混合式协作学习中，线上交互数量与线下高质量的交互数量与学生的学习成效呈强相关关系，线下交互数量与学生 学习成效呈弱相关关系.

Based on the practice of the blended collaborative learning in College Physics course， the quality of interactive content is established according to Bloom's taxonomy of educational objectives in the cognitive domain.It has been found that students' learning achievement in blended collaborative learning is strongly correlated with the quantity of online interaction and the quantity of conventional classroom high quality interaction， the quantity of conventional classroom interaction is weakly related to student learning achievement.
