On-boarding

Tan, Steinbach and Kumar (p.231) note that arm length and reading ability are strongly correlated. When you fix the age the correlation evaporates. I'm trying to find the confounding factor in this one: Failure to post a profile photograph or avatar is strongly correlated with failure to complete an online course. I think if I could make only one change to courses I work on, it would be to extend the on-boarding component. I like: mihi-mihi; team-building; practice assignments; assessment simulations; and real life face to face beach parties.
