Though argumentation is a key component of scientific knowledge construction practices, it rarely occurs in classrooms worldwide. Moreover, related literature in the context of genetics and evolution learning primarily addresses them separately. In contrast, this paper is part of broader research on genetics and evolution instruction taught…

This article focuses on students' discursive moves and reasoning practices while engaged in a task that requires making explanatory links between sickle cell disease and malaria. Both diseases pertain to key areas of the biology curriculum, namely, genetic variability and natural selection, and are connected to the theory of evolution of living…

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is…
