Students only need to be reminded once of upcoming assignments. I give the students the opportunity to ask questions, and then I remind them of what is due for the next class. I will also remind them to refer to their syllabus for any due dates. As an instructor, I work very hard on the syllabus, and review it the first day of class. I also stress the value of the syllabus to the student. I have found that most students can answer their own questions regarding due dates by referring to his/her syllabus.
