I try to make my classroom fun for the students but also make them aware that I am going to hold them to a higher standard. I often play or tease students (they know all in fun) but this makes them very comfortable with me. In opening lecture when I give them expectations I also make them aware that I am there for them at any time if they have any type of issue I dont mind them bringing it to me, but I always follow that up with, I may not be able to fix the problem but I might be able to at least make it understandable so you can deal with it. Of course if I can fix it I will do all i can. I have a very good rapor with my students and have been approached on many occations with concerns and Like I said I cant fix all of them but I believe the students have all at least left me with a better understanding of the issue and in most cases we have been able to retain the student and help on to a new carreer.
