My Take
My students' grades declined during the first month of assigning GMM. GMM does not provide students with any type of feedback, hints, or advice when they get a problem wrong, but they do provide them with penalties which makes it challenging to keep earning more points.
How I Use It
In the past I would assign my students problems on GMM- they would have to get 30 points throughout 7 days. Students would come up to me throughout the week expressing their frustration when they would get a problem wrong because GMM would not accept their answer in the format it was written. My students would try to play around and see what works but it would be time-consuming.
