Providing feedback that moves learners forward is another of Dylan Wiliam’s 5 key strategies. Research has shown that feedback in the form of comments only, motivates students to learn more and ultimately improves their grades. Feedback in the form of a grade actually de-motivates students and has no effect on their performance. (Butler, 1988)
In math class, the only things my students get back with grades on them are summative assessments. I have significantly reduced the number of summative assessments I use in high school math classes. Most courses are adequately covered with 5 to 10 well constructed summative assessments. Everything else goes back to the students with comments only.
The feedback I provide instead of a grade varies by student needs. Some students simply need me to circle the place in a problem where they started to go wrong. Those students can take it from there and correct their work with little direction from me. Others need some comment on what the next step might be. I try to provide as little scaffolding as I can get away with, while still letting them have enough to move forward. It’s a fine line. I want them to take ownership without me giving them everything. I don’t spend a lot of time on written comments. Most of the time I look at things quickly and arrange my class so I can talk to the students personally, as I described in the previous post. Those kind of groupings also allow students to get feedback from each other instead of just from me.
