I have written extensively about the emails and SMS messages I have sent to students at risk and the difference it has made to some students. I have not just concentrated on the negative, I have also been sending congratulatory emails to students who have performed well. For each assessment item, I sent an email congratulating all students who achieved a mark in excess of 85%. I have also sent congratulatory emails to all students who achieved Distinction and High Distinction grades. The final group of emails I sent were to a few less talented students who achieved great results through hard work and perseverance. I do not know if these emails have had any impact on these students' performance but I like to think that the positive reinforcement made them feel better at least. A few students have written back to me thanking me for my messages.
