For one revision guide, Oxford Revise for KS3 Science does many things. Each topic is explored following a simple three-step approach of knowledge, retrieval and practice. This approach is based on cognitive science principles and enables pupils to start to lock in their learning into their long-term memory. Key knowledge is comprehensively covered within Knowledge Organisers that are clear and accessible and designed with the cognitive load of the learner always in mind. As students work their way through the guide, they are encouraged to make links between the topics. Sets of retrieval questions follow to check and secure students' knowledge retention. Students can quickly see how well they have understood the topic and the areas that may need more study or support. The last step is for students to put their knowledge into practice with a variety of different practice questions. These range in difficulty giving all students the chance to test themselves and attempt more challenging questions. This guide establishes revision as a vital part of the learning process. The structure supports the development of revision as a positive habit and reduces stress when preparing for exams and assessments throughout their science journey.
