In a junior secondary context, I have used this to help students improve spelling by having them set targets each week and I then track their progress against those targets each week using a spreadsheet.
Using this blog post by +Kev Lister on colour coding goal attainment as inspiration, I was off.
While it took a little setting up to begin with, I now have a spreadsheet that enables me to enter student goals one day and their result following the test. The spreadhseet automatically generates a coloured square to let students know if they've achieved above or below their target.
And it's working.
The mean score has risen from just below 7 in week 1 to above 8 in week 6 and the splatterings of purple, indicating students achieving below their goal, is on the decline.
Initially I thought students may have been getting smarter at goal setting but a rise in the mean score and an effect size of 0.6 suggests to me we're on the right track.
It also gives me an excuse to get students out of their seat when they start tuning out and I ask them to drop their goal slip into the box.
