随着数字技术与教育的不断融合，在线教学模式成为未来教育的必然趋势。文章从课程属性特征的视角，对某双一流建设高校的学生—课程大样本数据，使用均值t检验和普通最小二乘回归方法，探讨课程异质性对学生在线学习成效的影响及作用机制。研究发现：在线教学提高了学生学习成效，且课程类型与课程学分异质性对此产生了差异化的影响。影响机制分析表明，课程类型和课程学分异质性对学生学习投入产生影响，间接影响了学生在线学习成效。基于研究结论，文章提出我国高等教育在线教学发展应采取包容审慎态度，重视课程异质性的差异化发展，制定激励学生主观投入政策等建议，为推动教育数字化转型提供借鉴。
【英文摘要】：
With the continuous integration of digital technology and education, online teaching mode has become an inevitable trend in future education. From the perspective of course attribute characteristics, this paper explores the influence of course heterogeneity on students' online learning effectiveness and its mechanism, using mean t-test and ordinary least squares regression methods on a large sample of student-course data from a double first-class construction university. The results show that online teaching improves students' learning effectiveness, and the heterogeneity of course types and course credits has a differential impact on this. The analysis of the influencing mechanism shows that the heterogeneity of course types and course credits have an impact on students' learning engagement and indirectly affects students' online learning effectiveness. Based on the findings, this paper suggests that the development of online teaching and learning in higher education in China should adopt an inclusive and prudent attitude, pay attention to the differentiated effect of course heterogeneity, and develop policies to stimulate students' subjective engagement to provide a reference for promoting the digital transformation of education.
