ABSTRACT In this study, a Delphi method was used to identify and predict the roles of blended learning approaches in computer-supported collaborative learning (CSCL) environments. The Delphi panel consisted of experts in online learning from different geographic regions of the world. This study discusses findings related to (a) pros and cons of blended learning approaches in CSCL; (b) blended learning for collaboration in various contexts including the narrative accounts of blended learning approaches in CSCL given by the Delphi panelist; and (c) the future of blended learning in CSCL, via three-phases of online survey questions. Implications for design issues and future research into blended learning and CSCL are also included. Keywords Blended learning, Computer-supported collaborative learning, e-learning, Delphi study

Portland State University (PSU) redesigned Introductory Spanish, a yearlong, multiple-section course. Because of funding and space limitations, enrollment had been arbitrarily set at about 690 enrollments annually. In some academic years, current offerings met only 50% of the demand. One faculty member coordinated the course content and taught one section; teaching assistants taught the 9-10 remaining sections. The DFW rate was approximately 25% from fall to spring. The redesigned course addressed inconsistencies among sections through improved planning, coordination and training of teaching assistants, and clear articulation with new universal second-language requirements in Oregon.
