Key concepts are essential ideas that help students develop a deep understanding of their subject and make links between different aspects. Key concepts may open up new ways of thinking about, understanding or interpreting the important things to be learned. Good teaching and learning will incorporate and reinforce a subject’s key concepts to help students gain: a greater depth as well as breadth of subject knowledge, confidence, especially in applying knowledge and skills in new situations, the vocabulary to discuss their subject conceptually and show how different aspects link together, a level of mastery of their subject to help them enter higher education, The key concepts identified below, carefully introduced and developed, will help to underpin the course you will teach. You may identify additional key concepts which will also enrich teaching and learning.
