When I first became a substitute teacher, I went through a week-long training session with 150 other established teachers, administrators, instructors, and trainees (me). The first day we formed (forming) into our various groups according to which campus we had been hired for (there were four) so we could go to the proper classes. And, depending upon what grade level we were teaching, we signed up for certain core curriculum classes. Then we divided into the classes and began rigorous training in those areas (storming). We were taught the curriculum and then had a chance to role play to test our skills. This gave us a taste of what we would be doing (norming). At first it was very hard, but we got better and better all week. By the end of the week we had a pretty good idea of what we were doing (performing). I might add that there were several "drop-outs" who decided this particular way of teaching was not for them. Those of us who were left and were coming back the next year were pretty much prepared to go on (ending). Because I was going to be a substitute teacher I pretty much had to take every single class and learn everything because I would be used for Grades K-6.
It was an intense week at something I had never encountered before, but I made it through and am now a pretty good substitute teacher!
