#1 being time, #2 being I don't have the curriculum for that far into the future, and #3 I needed to get to know my kids before I put hundreds of dollars worth of tech in their hands during class time.
I'm going to attempt an activity tomorrow and we'll see how it goes.
They took a quiz on Friday. Some did good, most did okay, and several did very poorly. They have a test on this Friday, so I really want the quiz to be a true "formative" assessment. Let's figure out what we actually know and don't know, and learn from our mistakes so we can do better on the test. I'm even going to give them the "perk" of earning a better grade on the quiz based on this activity.
I made short 1-2 minute videos explaining the answer to each of the 9 questions on the quiz.
(side note: I decided to use ShowMe for the first time and am very happy with it. I have always used EduCreations for short quick ones, but students can't watch those videos on my iPod touches so it kind of ruined the idea behind it. ShowMe videos work just fine!)
I made a QR code (qrstuff.com is what I use) for each video. I have printed them out and will post them around the room. I also linked to each video on our class blog under the Linear Functions Unit (kirchcourse1.blogspot.com; don't use too much this year but just starting to get things organized).
