Giving clear directions

I think it's extremely important to be very, very clear when giving directions for activities and things but especially so for things that involve grades such as homework and testing. To ensure this, I try to give them in many forms.

1. I will tell the students about tests at least 2 weeks before the test, giving them a reminder every class for the students who were absent.

2. I give them a little handout with the basic points.

3. I write the basic info on the board and give them a little spiel in class.

4. I make them tell me the info before they leave for the day. For example, "When is your test?" "What % is it?" "Where is it? Here or my office?"

I think you can never be too clear when giving directions to people who might not necessarily understand you :)
