Even though my courses are 'assigned' for a certain format such as asynchronous (there are other sections that are synchronous and blended), I do add an optional component with synchronous learning in terms of study sessions for the difficult, challenging concepts so I can communicate in real time with student's questions. I get positive feedback, achieve higher level of retention of content with learning assessment activities and higher exam scores. I'm a proponent for mixed methodology with online courses based on content, student characteristics and more.
