The start of a new semester!

The new semester begins and there is much enthusiasm  for having another set of fresh minds to mold, but this question always returns ............
How do I do things better with this new group of students?  In striving to improve my own teaching and hence, I hope, my students' learning experience, there is always a fear that maybe, the different methods may not work. They may not work for me..... and they may not work for my students. I will not know unless I try! So that is what I will do. Try, try and try again!!!
