I have learned or actually relearned how important it is to help students evaluate how they learn best and when they learn best and in what environment they learn best especially with an online course.  Time management is extremely important.  

I liked the way that students can show engagement can be designed with their unique learning method so that they get the most out of the exercise. 

I learned how important it is to use a design that will actively engage students. 

I learned how important it is to have clear communication of all parts of the course and to incorporate active learning. 

I have learned that online courses need to be easy to navigate and sequential and lead to the course objectives.  The courses need to be multi-sensory to engage each student's learning style and increase retention of material.
