There are different styles of learning.  Those students who are quiet might need a personal message to help them stay involved.  Those students who are procrastinators need you to give them the expectations in order for them to stay focused.

Try to seek feedback from students on a regular basis. Solicit student feedback about how the course is progressing. Are they getting out of the course what they want? Is the course fulfilling their expectations? Are there some things you are doing that they do not like?

What is important is that you establish a rapport with the students.  You can create a short bio, as well as have them create a short bio and have each of the students share theirs with each other.  If there are students who are not engaged, you can send them a personal email, using diplomacy when talking with them.

It is important that we are familiar with the teaching platform and can familiarize the students with the platform and expectations from each course.
