Pham, Lam; Tytler, Russell – Research in Science Education, 2022
Many researchers have reported that bridging analogies can productively support students' scientific meaning-making. How this can be understood semiotically is, however, not well understood. This research followed an ethnographic case study approach to investigate Year 11 students meaning-making through a process of transduction (Kress, 2000;…

Mohan, Lindsey; Chen, Jing; Anderson, Charles W. – Journal of Research in Science Teaching, 2009
This study reports on our steps toward achieving a conceptually coherent and empirically validated learning progression for carbon cycling in socio-ecological systems. It describes an iterative process of designing and analyzing assessment and interview data from students in upper elementary through high school. The product of our development…
