At the end of each module, I require students to conduct a 10 minute speech with outlines, presentation materials and a question and anwer session in order to demonstrate their understanding of the material that was presented during that module. This is an effective time management tool because I can evaulate them at the time that they are giving the presentation and there is nothing for me to take home to grade. Also, this allows students who have a hard time writing what they understand to show me orally that they really do comprehend the material. It also boosts their self-esteem, allows them to gain confidence in what they know and it reinforces the material for the other students who listen to the presentation.
