. How you reviewed the materials (Did you spend 5 minutes browsing, 2 hours trying it, or actually use it in teaching-learning activities?).
I spent about 15 mins. at this website and then something happened and my computer crashed.
2. The quality of content (Does the materials accurately present concepts and models that are educationally significant?)
I found the website to be fun. It is a great visual tool. It will help those who learn by doing or learn by seeing.
3. The potential effectiveness for enhancing teaching and learning (If used appropriately, will students' learning and faculty's teaching be enhanced?) It defintely a effective learning tool for both teacher and student. I really was having fun with this one and I got to see the graph being made as the ball was bouncing.
4. The ease of using the materials (Will first time users find it easy to use the software?)
It was quite easy to use until my computer locked up at this site.
