Quick response and feedback
Students may neglect to learn when teachers do not respond in a timely manner. Please respond quickly, and give marks and comments after each assignment, and test. In addition to grades, constructive and motivating comments really work. When students contact for help or have questions, it is best that the teacher responds within 24 hours.
Some students complain about online courses and those discussions go on for so long that students don't really engage with each other. With little or no response from others, participants are also not motivated to return to the discussion. You need to set a reasonable time limit for students to be flexible when participating. Teachers can comment with students and make sure the discussion is on track.
