一种新的在线讨论方法,将学生讨论置于课程内容的边缘,可以提高学生对课程材料的参与度。然而,在高入学率的班级里,大量的评论会让学生感到不知所措和害怕。一些人对大量潜在的在线互动感到沮丧,并认为与他们的学习缺乏直接关联。同样,当优秀的讨论(他们认为对所有人都有价值)在混乱中迷失时,讲师也会感到失望。为了解决这些挑战,我们提出了视觉聚焦机制,以增加选定评论的显着性。我们在美国一所大型公立大学的两门高入学率的生物学课程中试用并部署了多种设计。访谈、调查和一项对照实验表明,在大量注释的文本中突出相关评论对学生的参与度有积极影响,衡量标准是他们对评论的注意力,以及他们报告的认可感和自豪感。学生们还报告了他们对某些聚光灯设计的偏好。
A new approach to online discussion, which situates student discussions in the margins of the course content, can enhance student engagement with course materials. However, in high-enrollment classes, the large number of comments can overwhelm and intimidate students. Some become frustrated by the volume of potential online interactions and by a perceived lack of immediate relevance to their studies. Likewise, instructors are disappointed when outstanding discussions, that they deem valuable for all to see, get lost in the clutter.To address these challenges, we propose visual spotlighting mechanisms for increasing the saliency of selected comments. We piloted and deployed multiple designs in two high-enrollment biology courses at a large public university in the United States. Interviews, surveys, and a controlled experiment show that spotlighting relevant comments in heavily annotated texts positively affects students' engagement, measured in terms of their attention to comments, and their reported sense of validation and pride. Students also reported their preferences for certain spotlighting designs.
