I think that having at least 1 session per week that is a virtual face-to-face format (such as Zoom meetings) helps students relate with one another.  It may be harder in a TRUE online course, but a hybrid course where they see each other at least part of the time on campus really lends itself to helping them come together as  agroup, even if virtually.  This could reduce attrition, in addition to identifying individuals' needs.

I've always thought that the use of "LOL," smiley faces, etc. was unprofessional to use in email communication, so I felt these should be avoided in online discussions.  However, I'm learning that students may feel more connected, less intimidated, and better able to understand each other's intent with these allowed.  I feel that I should specify which "tone" I would like for different assignments (i.e. conversational/emojis allowed versus professional) to incorporate different types of communication.

Our program is in an in-person format but has transitioned temporarily to online delivery due to Covid 19 restrictions.  In the past, I always did my introductions in person, but I see the value in posting a Bio on the CMS, even if I've already done it in person.  That way, the students can look back at it later on.  Plus, having the students create their own bios helps me create a connection with them by relating concepts in the course with their backgrounds.   

I would like to be better at designing some activities that don't have to be done in linear fashion, because some students like to work ahead and/or become more interested the more they learn to apply the information.  

Our students received an orientation to their Course Management System early on in the program, but I think it would be helpful to have a "refresher" on how to use different aspects of the system further along, because they forget things!
