The Blended Learning & Teaching report, the fourth in the four-part series, begins at the launch of the iEds’ second year of training and focuses on their immersion in blended teaching and learning. For more background about the program, please see the first three reports: part one introduced and detailed the iEd program and included reflections from the administrative and instructional design teams involved in the development of the program, as well as reflections and feedback from the iEds themselves; part two examined the iEds’ collegiality, specifically their cohesion with and centrality in the group through an analysis of their blog posts and comments; and part three examined the iEds’ performance indicated by their caseload trends and students’ course outcomes, including course completion status and final grades over the period of four academic terms.
