I love the use of peer assessment. I especially use it for things that would take me forever to grade. This year I'm going to be attempting to use it for lab reports. Last year, grading lab reports was extremely difficult, because I would need to collect all of their notebooks. I couldn't take them home because there were too many, and they were generally difficult to read through especially if they were disorganized or in poor handwriting. Teachers who have used lab notebooks for years have told me that it takes them 3 weeks to get through grading theirs and then by that time they have more lab reports to grade. Gragh! So I decided: scientists use peer review. We're going to use peer review. I'm going to let students do the majority of the grading and feedback work. (specifically, I will have the students provide peer feedback based on a rubric, allow students to make changes as necessary and then allow them to self-grade their labs based on a rubric) Then I will briefly scan the work, the peer feedback, self-grades, and provide a single letter grade for multiple labs at once which will be the only one to go into the grade. I'm hoping this will cut down on my grading greatly. I know many people are leery about peer grades because there seems to be legislation affecting many states about who can see the scores of students. I don't think this law is in effect in California and I'd be working around it anyway by just allowing students to provide peer feedback and self-grades which are different from the official grade anyway. I use self-grading frequently for homework assignments, and peer correction for quizzes though. How do you feel about peer grading? If you use it, how do you use it in your class?
