Price, Gareth; Bevins, Stuart – School Science Review, 2021
This article offers an outline of 3D science that conceptualises science around three dimensions: domain knowledge, evidence-management procedures and psychological energy. We propose that this model could underpin a rigorous, effective and motivating approach to science education in schools. We show how self-determination theory offers useful…

Hardman, Mark – School Science Review, 2017
Doing science involves the development and evaluation of models. These models are not objective truths but can be understood as explanations, which scientists use to explore and reason about an aspect of the world. Learning science involves students expressing and engaging with models in the classroom. However, this learning should not be seen as…

Talbot, Christopher; Vickneson, Kishanda – School Science Review, 2013
The aim of this "Science Note" is to describe how to test the electron-sea model to determine whether it accurately predicts relative electrical conductivity for first-row transition metals. In the electron-sea model, a metal crystal is viewed as a three-dimensional array of metal cations immersed in a sea of delocalised valence…
