A learning progression characterizes variations of the practice that are appropriate for learners, and a sequence of successively more complex versions of that practice, building from the understandings and practices learners bring to the classroom to a more sophisticated view.
A learning progression for a scientific practice outlines:
- a model of the target practice appropriate for learners
- the starting points of learners' intuitive understandings and practices,
- a sequence of successively more sophisticated understandings and practices, and
- instructional supports that help learners develop the practice.
