#3: Peer Assessment
I first learnt about the power of peer assessment back in 2008, when I had just moved to Thailand.
As a keen young teacher with two years of UK teaching experience, I found myself teaching students who were all very keen to do their best. Homework assignments and classwork seem to come my way on a real-time, live-stream basis, and I soon found myself inundated with work to mark.
At first, I tried the traditional methods of using a green or red pen to write lengthy comments on each piece of work. I had learned from my training in Assessment for Learning in the UK that written comments that help the student to improve were much better than a letter grade or a score followed by a ‘Well Done’. I’d learnt about the ‘two stars and wish rule’ where I’d write two positive things about the work and then one item or target for improvement.
These ideas were great in theory, but I found that my weekends became shorter and shorter as I tried to write effective comments on every piece of work that came in. I was spending less and less time doing the hobbies I enjoyed, and I became quite the old grouch.
I finally expressed my concerns in the staff room one day and a colleague of mine said: “You should do more peer assessment”. She was right.
I instantly started getting my students to mark their own work, and reflect upon it, and the results were astounding: My weekends became ‘me time’ again, and students seemed to learn better than they would from receiving my comments.
As I continued to develop my skills in assigning proper peer-assessment, I discovered that I was sometimes making some catastrophic errors. I refined my strategy over the years, and came up with this six-step system:
Step 1: Make sure that the work you set has an official mark scheme or set of model answers associated with it. There’s nothing worse than trying to ‘guess’ the best answers along the way as you’re trying to get the kids to assess the work. Make your own mark scheme if necessary, but make sure the answers are clear.
Step 2: When it comes time for the kids to assess the work, ask them to swap their work with someone else in the class. Alternatively, if this doesn’t work for your particular class, then collect the work in and redistribute it.
Step 3: Ask each student to get a coloured pen ready to mark. Red and green are good. You may wish to have a set of special ‘marking pens’ somewhere in class that the kids can use whenever they mark each others’ work.
Step 4: Print the official mark scheme and give a copy to each student. This has the advantage of providing a permanent copy for each student to keep and allows you time to help students as they mark. Projecting the answers onto a screen can also work, but you may find that students cannot see and that you may have to scroll through at a pace that’s not suitable for every student. Printing a copy, or sharing it with the schools VLE so that students can access it via a tablet or laptop, is best.
Step 5: Make it very clear that students should tick the answer if it’s correct, and make full corrections if it is wrong. The mere act of writing out the model answer onto the work being marked will reinforce the concepts into the subconscious mind of the student.
Step 6: Let the students give the work back. Collect it in at the end of the lesson so that you can glance through and check that everyone has peer-assessed properly. If anyone hasn’t, then make them do it again.
Once work has been peer-assessed, you can sit down with individual students and have ‘progress conversations’ designed to pinpoint areas of weakness and highlight areas of strength
You have to be quite organised with this method (e.g. making sure you print the mark schemes on time). However, this will save you loads of time and will definitely help the kids to learn properly.
