If you are interested in using the materials, you can sign up below to get a free pdf copy of the available books. You are allowed to use these in class, as long as you agree to an educational collaboration, in which you share your educational experience with me. I would want to know how you used the materials, what worked, what didn't work, and what relevant reactions did you received from your students. I will use this feedback to develop further materials. I appreciate both your interest and feedback a lot! And I'll be really happy to assist in implementing these materials to further enrich your teaching.
