Niroj Dahal; Binod Prasad Pant; Bal Chandra Luitel; Basanta Raj Lamichhane; Tara Paudel – Online Submission, 2024
This research explores two methods through which ten preservice math teachers develop an understanding of trigonometric values. Using the unit circle, preservice math teachers engage in knowledge-building activities such as paper folding and GeoGebra application. Grounded in Altman and Kidron's 2016 didactical design research, this study examines…
