Today, my algebra I class worked on scientific notation. After a video and guided practice, I had the students go on and do the first quiz under exponents as they are supposed to be fairly good at using exponents. Unfortunately, the average score was about 5/10. I think many of the students just put an answer to get done rather than really looking and trying.
I do enjoy these apps because they give me a way of getting immediate feedback on student performance and behavior. In addition, it gives students a chance to practice taking computer based tests. Their major state tests will be computer based and any practice I can give them will help.
