We are using a new system at school that allows me to build exams, tests and quizzes.

I can have the exam reveal the answers immediately or make them wait until the all submitted.    I can time it, and when complete,  show the class by question the % or number that they got correct.  Real-time.   It was fun after the test today showing them the results and correct answers.

The test today had 11 questions that I thought were easy, but for most it was hard.  Only 1 student out of 34 got 100.   The average was below 60.

It was very interesting listening to them go through trying to solve the questions.  All of this was open book too.

In addition to getting them to review and truly have to think, this  exercise will also help in the future when I ask them to pay attention and get their assignments done.   Technology, I love it.
