<p>&nbsp; We are completing Physics, it has been difficult and I wish I had been able to implement this technology for this module. We have had many sessions where students worked about problems on the board it was very exciting and interactive. One of the best learning events of the class. I also had the students formulate a problem using the knowledhge they had acquired from the lecture. It became very competetive and a lot of learning happened that day. The problems became more difficult as well as use of scientific notation. I can identify with what you are speaking of.</p>
