哈佛商学院正式推出在线课程

So, what has Harvard learned after sending two cohorts through the program? The second B-to-B cohort had an 80% completion rate and engagement rates off the chart, much like the pioneer cohort. The completion rate fell by five percentage points, largely because the second cohort was comprised entirely of full-time managers and employees who often found it difficult to complete all the work. Learners find that it takes about 10 hours a week over the two-month program to get all the work done. Participants also are prevented from moving forward unless they complete a module within a two-week timeframe, a deadline that makes it hard to catch up when students fall behind.

那么，送走了两批学生之后，哈佛从中总结出什么经验教训？第二批B2B学生完成率达到80%，学生参与率同样很出色，与第一批学生类似。学业完成率下降了5个百分点，很大程度上是由于第二批学生全部由在职的管理者和员工组成，经常难以完成所有学习任务。学习者发现，在两个月课程期间，完成所有功课需要每周拿出10个小时。而且，参与者只有在两周内完成一个模块才能进行下一个模块，这个最终期限让落后的学生很难赶上进度。

Anand says that they initially tweaked the program to strike a balance between taking advantage of the asynchronous nature of online learning while preserving some synchronous activity so that students can help their classmates at certain points. “In the first cohort, we had five gates—or deadlines for the completion of work—across all three courses,” he says. “In the fall, we moved to a slightly different structure. If you have all three deadlines on one day, it becomes very hard to catch up. So we put in many more deadlines, 17 in all, in the fall. The moment you go to 17, students have to keep up continuously but you also want to preserve some flexibity for them. So we are now moving back to something in the middle, about 10 deadlines with some overlap for when material is released to allow some students to move faster.
