Being actively engaged in a task is often associated with critical thinking. Cultivating critical thinking skills, such as purposefully reflecting and analyzing one's own thinking, is a major goal of higher education. However, there is a challenge in providing college students opportunities to clearly demonstrate these skills in online courses. This research explores the effectiveness of incorporating word clouds--visual representations of word frequency in a given passage of text--into online discussions. We sought to establish whether implementing word clouds in online discussions would result in a higher incidence of critical thinking and engagement. Survey results from undergraduate participants (n = 132) revealed that students analyzing text in word clouds reported moderately higher scores on critical thinking and engagement than students analyzing the text in a linear fashion. A positive relationship was found between critical thinking and engagement, as well as peer interaction. This strategy can be applied to a wide range of educational environments to stimulate critical thinking and engagement.
