Nieva,
Quizzes are a terrific way to ascertain what your students have learned. I like to allow them to retake quizzes until they earn 100%. This way, the quiz itself is a learning experience. Do you agree, or do you have a different take on quizzes?
What would you think of students creating presentations that their classmates could view rather than just emailing them to you? Just a suggestion :)
Thanks for your input!
Jane
