They provide a way of addressing difficulties in teaching a physical science topic where a teacher has limited understanding, as well as a way of engaging teachers in becoming more confident and competent in lesson preparation and presentation, that will improve pupil experience in the classroom and laboratory. They are appropriate for use with paired planning and paired teaching with ASTs.
