Karen Wilkins established two reading circles - a face-to-face group and an online Google group - to encourage her students to discuss what they were reading outside of class. The face-to-face group had three participants who learned new vocabulary in context, developed their speaking skills, and attended almost every session. In contrast, the online Google group had ten participants but no one ever replied to posts, so there was no discussion. Based on this experiment, Karen concluded that an in-person gathering is more effective for discussion than a solely virtual platform.
