Primary and concrete discursive objects (d-objects) play an important role in this process, forming different ... -
Task design using a realization tree: The case of the derivative in the context of chemistry
Radmehr, Farzad; Haghjoo, Saeid; Reyhani, Ebrahim (The Learning and Teaching of Calculus Across Disciplines – Proceedings of the Second Calculus Conference;, Chapter, 2023)We have recently developed a realization tree for the derivative at a point based on its five main realizations (See Haghjoo et al., 2023). In this paper, we discuss how this realization tree can be used for task design, ...
