<p>@craigmotley99</p> <p>I have the same issues. I feel that some of the &nbsp;students are trying to feel out the class&nbsp;in a&nbsp;attempt to get a grip if this is what they really want to pursue as a ocupation. I try to keep&nbsp;the lectures as real as posible and also pose thought questions back at the class to get them to use what the discusion was about to understand what issues will cause&nbsp;real failures. Most students like the idea but have trouble grasping what caused the primary failure. This seems to get them interested.&nbsp;</p>
