But the most useful thing I've done is trialled it in my lessons, firstly as a self assessment tool and then as a structure to base conversations about the quality of the student work. Both times I have shared what I was doing and asked for feedback. My students have responded in spades, some obviously finding even my crudest attempts useful.
This piece of student work was marked together discussing where on the taxonomy she thought she was. It uses the original language which I have changed, but will probably change back! You can see I am still going back and forth on this one. I have added a couple of extra levels to act as stepping stones. I will find out if they are need.
So my plan is to use the wall display to help permeate as many aspects of my teaching as I can, I will design assessment scheme for specific pieces of work based around this, use it as a self assessment tool, try to correlate it with the National Curriculum levels, refer to it in my feedback to students both verbally and written and I will also with students display exemplar pieces of work at each level. I think this tool with a purpose has legs. Now, I just have to go and use it!
