Thank you Dr. Meers! I will get with our other instructors to put a type of pretest together, and ask them to also keep an eye on their classes comprehension. We have a quiz every week to two weeks, and sometimes their is so much material to cover I'm not positive that my students are keeping up. I like the team idea, because in the field my students are learning about, we work in teams every time we go out to do a job, and it is always better to have team effort than for one to take on a situation by oneself. Not to mention that it is very dangerous for one person to try and do things alone. This works as at least a two fold helpful hint! I can see where my students are with comprehension and get them into thinking about team effort as they get out into the real world situations. Thank You!
