Case Study: Coordinating Among Multiple Semiotic Resources to Solve Complex Physics Problems
Nandana Weliweriya, Eleanor C Sayre, Dean A Zollman
This work examines student meaning-making in undergraduate physics problem-solving. We use a social semiotic perspective to sketch a theoretical framework. The social semiotic appr…
Standing fast: Translation among durable representations using evanescent representations in upper-division problem solving
Nandana Weliweriya, Tra Huynh, Eleanor C Sayre
Mastering problem solving requires students to not only understand and apply physics concepts but also employ mathematics and mathematical representations (sketches, diagrams, grap…
The effectiveness of 'pencasts' in physics courses
Nandana Weliweriya, Eleanor C Sayre, Dean A Zollman
Pencasts are videos of problem solving with narration by the problem solver. Pedagogically, students can create pencasts to illustrate their own problem solving to the instructor o…
Varied reasoning schema in students' written solutions
Nandana Weliweriya, Justyna P. Zwolak, Eleanor C. Sayre +1
The Mathematization project investigates students' use of mathematical tools across the undergraduate physics curriculum. As a part of this project, we look at intermediate mechani…
