This has literally just happened, I am still in shock, even after filling out all the paperwork regarding the situation. The student is "cocky" and rubbed the PGCE student up the wrong way, and had the class being exceedingly loud while I ran to do some photocopying for the PGCE student. The LSA in the room said that the PGCE student shouted at the kids to "shut the hell up" then threw the dictionary at the boy who had told her "calm down love- its on an english lesson." I have dismissed the PGCE student and her tutor is coming in tomorrow morning with her to discuss the problem. I think I may have just ruined her life! Was I right to do this? If she can snap so quickly, she shouln't be around kids. The LSA said she didn't even ask the students to be quiet in a calm and normal voice. Another teacher walked in when she heard the class scream when the dictionary hit the student and then things have unfolded from there. What would you have done?
