The Levels Mountain is an approach to teaching that has been developed by Thinking Frame. It is a way of enabling teachers and pupils to understand what progression through the levels of the National Curriculum for Science 'feels like'. It helps teachers and pupils to visualise progression and to see what needs to be done to reach the next level.
The levels are described in terms of models and modelling.
I have provided a Powerpoint presentation to explain the basics of the levels mountain as a way of supporting progress at KS3. A similar mountain could be devised for KS4. The presentation includes exemplars of pupils' work which demonstrate the usefulness of the approach.
