This study investigated students' use of an asynchronous communication tool as part of a "hybrid" class that included face-to-face meetings and Web-enhanced instructional activities. The researchers analyzed communication patterns used during asynchronous discussions about class projects and case studies. Also, they examined type of interactions that occurred among and between students. Through review of online discussion transcripts, the researchers identified patterns of communication and types of interaction including how the e-board supported student learning. Findings and implications to teaching and learning were discussed. (Contains 3 tables and 1 figure.)
