When I teach in the classroom, I sometimes design later portions of the course based on how the students do on assignments, tests, and class participation in the early parts of the course. In other words, I design the course around the students after I learn about them. How much of an e-course is set in stone before the class begins? If I can unlock parts of the course later, it would seem I can use the above strategies with an e-course. Any comments? Thanks!
