The development of a learning progression for celestial motion

This study can be used by ISE professionals as a source of ideas to guide thinking about the use of a learning progression framework for astronomy education. It is evident from the results that target instruction is necessary as it encourages students toward developing more sophisticated understandings of topics. As students can articulate their learning progressions, they can be useful in measuring students’ understanding relative to a conceptual goal. In addition, this approach connects informal learning to formal learning.
