Learning progressions are a systematic way of mapping out the sequence of learning steps that individuals go through as they develop their understanding and skills in a particular subject area. These progressions outline the key concepts, skills, and knowledge that students should acquire at each stage of their learning journey. Learning progressions help educators to identify where students are in their learning process, and can inform instructional practices and curriculum design to better support students in their learning goals. They can also be used to track student progress over time and provide insights into potential areas for intervention or support. Overall, learning progressions provide a roadmap for educators to effectively support and challenge students as they progress in their learning journey in a specific subject area.
