“There is no doubt that blended learning can be as effective and often more effective than a classroom,” said Mr. Moore, who is also editor of The American Journal of Distance Education. He said, however, that research and his experiences had shown that proper design and teacher instruction within the classroom were necessary. A facilitator who only monitors student progress and technical issues within virtual labs would not be categorized as part of a blended-learning model, he said. Other variables include “the maturity and sophistication of the student,” he said.
