Making learning last: teachers’ long-term retention of improved nature of science conceptions and instructional rationales
2017
ABSTRACTDespite successful attempts to improve learners’ nature of science (NOS) conceptions through explicit, reflective approaches, retention of improved conceptions is rarely addressed in research. The issue of context for NOS instruction has implications for this retention. Whether to contextualise has been the question occupying science educators’ attention. We think this question is misplaced.
