The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

In science education, epistemic vigilance plays a key role in the development of students' critical thinking by supporting students' abilities to evaluate the expertise level of the source and to evaluate the claim itself, using rigorous scientific standards and appropriate argumentation heuristics. Based on previous studies, which suggested two…

Language and argument are epistemic tools that learners can use to help them generate and validate knowledge for themselves, as emphasized in NGSS and previous NRC reports. Not all learning environments elicit or support the use of these epistemic tools equally, thus affecting how students grow in competence in relation to their use. The present…

In order to deepen students' understanding of natural phenomenon and how scientific knowledge is constructed, it is critical that science teachers learn how to engage students in productive scientific argumentation. Simulations for teachers are one possible solution to providing practice-based spaces where novices can approximate the work of…
