Two important influences on students' evaluations of teaching are relationship and professor effects. Relationship effects reflect unique matches between students and professors such that some professors are unusually effective for some students, but not for others. Professor effects reflect inter-rater agreement that some professors are more effective than others, on average across students.
We attempted to forecast students' evaluations of live lectures from brief, video-recorded teaching trailers.
Participants were 145 college students (74% female) enrolled in introductory psychology courses at a public university in the Great Lakes region of the United States.
Students viewed trailers early in the semester and attended live lectures months later. Because subgroups of students viewed the same professors, statistical analyses could isolate professor and relationship effects.
Evaluations were influenced strongly by relationship and professor effects, and students' evaluations of live lectures could be forecasted from students' evaluations of teaching trailers. That is, we could forecast the individual students who would respond unusually well to a specific professor (relationship effects). We could also forecast which professors elicited better evaluations in live lectures, on average across students (professor effects). Professors who elicited unusually good evaluations in some students also elicited better memory for lectures in those students.
It appears possible to forecast relationship and professor effects on teaching evaluations by presenting brief teaching trailers to students. Thus, it might be possible to develop online recommender systems to help match students and professors so that unusually effective teaching emerges.
对学生教学评价有两个重要影响因素,即师生关系效应和教师效应。师生关系效应反映了学生与教师之间的独特匹配,即有些教师对某些学生格外有效,但对其他学生并非如此。教师效应反映了评分者之间的一致性,即平均而言,有些教师比其他教师更有效。
我们试图通过简短的教学预告片来预测学生对现场讲座的评价。
参与者是美国五大湖地区一所公立大学的145名修读心理学入门课程的大学生(74%为女性)。
学生在学期初观看预告片,数月后参加现场讲座。由于部分学生观看的是相同的教师授课,统计分析可以分离出教师效应和师生关系效应。
评价受到师生关系效应和教师效应的强烈影响,学生对现场讲座的评价可以从他们对教学预告片的评价中预测出来。也就是说,我们可以预测哪些学生会对特定教师的授课反应特别好(师生关系效应)。我们还可以预测哪些教师在现场讲座中平均能获得学生更好的评价(教师效应)。在某些学生中获得异常高评价的教师,也能让这些学生对讲座有更好的记忆。
通过向学生展示简短的教学预告片,似乎有可能预测师生关系效应和教师效应在教学评价中的作用。因此,有可能开发在线推荐系统来帮助学生与教师匹配,从而产生特别有效的教学效果。
