Today we decided to give another pre and post test to see if we could recreate our success with the Wii and numbers on the number line (see this post for more info). Chris wanted to do a lesson on ratios. All of the students came into the lab and took our pre test using Google Forms.

Here are the questions and some of the answers from a group of students.

As you can see, the answers were all over the place. She began by discussing ratios and the vocabulary involved. She talked about the relationship between the first number and the second and the format which ratios can take (using the word "to", posted with a semicolon or as a fraction). We made a point to remind the students that the relationship that you are asking for will dictate the results of the ratio. It will be wrong if you put the correct numbers, but in the incorrect order! After this discussion we used the Wii to bowl.

We had 4 players registered and each student was able to bowl one frame. This way we got all the students involved in game play. After each throw Chris would ask for a different ratio. For example, the ratio of pins hit down to total pins. Or pins hit down to pins remaining. After a few frames we increased the difficultly a little and asked questions like the ratio of odd numbered scores to even numbered scores. Each time the students had to write the ratio in multiple ways. We were able to complete several frames (but not a complete game in the time allowed). Bowling lended itself to lots of ratio questions. We were able to stop play in between each bowler and ask a different question without interrupting game play/learning. There were plenty of numbers and plenty of options. Later that day (you can see the timestamp in the first column) the students took the post test (the same exact test). Here are the results (again) of some of our students.

While there are some formatting mistakes (some of which can be attributed to Google Spreadsheet trying to "help" with the formatting) you can see, we had much better results, but still have some students who didn't get all aspects of the concept. We are working on that!

We had good feedback from the students. They enjoyed bowling and seemed to do a good job with the ratio options.
