Teachers' Customizations of Storyline Science Curriculum: Adapting for Their Students and Instructional Contexts

Science Education, EarlyView.
ABSTRACT Curriculum materials can play an essential role to help teachers shift their instruction. However, curricular enactment does not look identical in every classroom, because teachers need to be responsive to their students. In this study, we investigated the customizations teachers made while enacting storyline science curriculum.

The Epistemic Generativity of Using a Model of a Big Idea

Science Education, EarlyView.
ABSTRACT Science instruction should involve learners in generating and warranting ideas, what we call epistemic generation. In modeling instruction, epistemic generation should be achieved by coordinating a model structure with the experienced world in reciprocal directions denoted as developing models and using models. In the former, a model structure

Synchronous reluctance machines: performance evaluation with and without ferrite magnets

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Nowadays, a great interest in the efficiency and the cost of electrical machines has been noticed. Therefore, Synchronous Reluctance Motors (SynRMs) have become more attractive alternative for induction and permanent magnet (PM) synchronous machines in several industrial applications.

‘Vitamins’, shortcuts, and athletic citizenship in Ethiopia and Cameroon: considering sporting ethics beyond biomedicine « Vitamines », courts‐circuits et citoyenneté sportive en Éthiopie et au Cameroun : l’éthique du sport, au‐delà de la biomédecine

Journal of the Royal Anthropological Institute, EarlyView.
This article argues that the current way of thinking about ethics in sport in primarily biomedical terms, and in particular in terms of the presence of particular pharmaceutical substances, fails to account for broader notions of sporting ethics and fairness in the Global South.

Five‐year outcome of laparoscopic transanal total mesorectal excision in a single centre—A training model to acquire a new surgical technique

Surgical Practice, EarlyView.
Abstract Background Laparoscopic transanal total mesorectal excision (TaTME) has been widely adopted globally. Short‐ and long‐term outcomes vary across different localities, especially during the learning phase. Method and patient The first 100 cases of TaTME performed by two experienced colorectal surgeons between 2015 and 2019 were reviewed. The aim
