Evolving Physics Education.
Expert TA is an online homework and tutorial system for introductory physics. We believe that students learn physics best by solving problems. Everything we do is based on that.
Our mission is to provide physics instructors and students exactly the tools they need to make the entire problem solving process the best learning experience it can possibly be. Rather than sticking to right versus wrong answers, generic hints, or tired old problems, Expert TA steps up and out.
