I'm new in the instructional field and I'm having to learn to keep my pace slower because of some (not all) students not catching all the details involved with the subject at hand. I am also experiencing what I call the "timid" class, where no one wants to take a chance a speak out. Sometimes it is very difficult to know or see if my students are actually understanding the subject matter. Where I am becoming concerned is the fact that as a class, we have to move forward to get everything into our class time. Some of the material I am teaching on has to do with safety for not only the individual but for many others that might be involved on a site. My question is: How do I go about checking to see if everyone is actually understanding, before test time?
