These are my personal recommendations for members of staff producing Blackboard materials.
Students are very concerned about printing costs.
Make sure that course materials are concise and presented in an effective way. Proportional fonts such as times roman, take up less space than other fonts such as Arial. Double column format reduces the number of pages and also allows smaller fonts to be used. My materials use double columns with the 10pt times new roman font. Many students have difficulty identifying which material is important.
