Having the multiple choice tests built into every module allows me to monitor student progress more effectively. I rate myself a good teacher, but I still would have missed some of my students' gaps if I had not had the test results in front of me. I'm using the Yacapaca versions of the tests and the analysis page really makes any problem areas leap out at you.
I've just used these for the first time and they really do motivate the students. They've also helped to disrupt up one particular group of boys who were habitually following the lead of the most vocal, who was unfortunately also the thickest.
