Jin, Hui; Johnson, Michele E.; Shin, Hyo Jeong; Anderson, Charles W. – Journal of Research in Science Teaching, 2017
This study was conducted in a large-scale environmental literacy project. In the project, we developed a Learning Progression Framework (LPF) for matter and energy in social-ecological systems; the LPF contains four achievement levels. Based on the LPF, we designed a Plant Unit to help Levels 2 and 3 students advance to Level 4 of the LPF. In the…
