For example, how long should the course be, how should the topics be arranged, what practical exercises should be included, etc. Quality of the exercises is another key factor in good courseware. The exercises need to be simple so that the students do not get confused and they must illustrate the subject matter that you are teaching. Also, the exercises should be relevant the students should be able to identify with the examples. Presentation is critical.
People react well to courseware that is pleasing to the eye.
If the manual looks good, then the students feel good about the course. Make sure that it is clean, clear and uncluttered. It helps to have lots of white space on the page. The text itself should explain the subject matter in simple terms. Explanations should be adequate but should not include unnecessary information.
