Challenge: While I was at Sheridan, marking and general organization was taking a large amount of time. It was taking instructors 10 hours per week to mark the lab work the students were generating.
Solution: Created a WordPress Plugin that would allow the students to test their own work, as well as the instructor to do a mass-test of all the students work. The plugin would also keep track of what class the student was in and generate how active they were in the forums. This solution became more generic with the goal of sharing it with other instructors.
Result: With the automated testing, it reduced the marking time to less than an hour per week.
