Produced in partnership with OCR, University of York Science Education Group and Nuffield Foundation, these second editions of the Twenty First Century Science resources provide the best support for the new specifications and make the transition as smooth as possible. The Revision Guide helps students prepare for their exams.

This ultimate study guide with in-depth GCSE course coverage is all you need for exam success. Revise GCSE Physics has everything you need to achieve the GCSE grade you want. It is written by GCSE examiners to boost learning and focus revision.

These new Twenty First Century Science resources have been written alongside the 2016 specifications. Students of all abilities are supported with separate Higher and Foundation books, and maths and practical skills are developed throughout. An assessment item for every assessable learning outcome provides evidence of students' progress.

Written by examiners and practising teachers, each book in this series contains activities and useful features intended to aid understanding. Knowledge is tested throughout, with progress checks at the end of every chapter and practice questions at the end of each section.

This ultimate study guide with in-depth GCSE course coverage is all you need for exam success. Revise GCSE Biology has everything you need to achieve the GCSE grade you want. It is written by GCSE examiners to boost learning and focus revision.

A revision guide for those doing separate sciences, it aims to cover what they need to know for their course. It contains separate science content that double science people don't have to cover.

This second volume of papers from the ATC21STM project deals with the development of an assessment and teaching system of 21st century skills. Readers are guided through a detailed description of the methods used in this process. The first volume was published by Springer in 2012 (Griffin, P., McGaw, B. & Care, E., Eds., Assessment and Teaching of 21st Century Skills, Dordrecht: Springer). The major elements of this new volume are the identification and description of two 21st century skills that are amenable to teaching and learning: collaborative problem solving, and learning in digital networks. Features of the skills that need to be mirrored in their assessment are identified so that they can be reflected in assessment tasks. The tasks are formulated so that reporting of student performance can guide implementation in the classroom for use in teaching and learning. How simple tasks can act as platforms for development of 21st century skills is demonstrated, with the concurrent technical infrastructure required for its support. How countries with different languages and cultures participated and contributed to the development process is described. The psychometric qualities of the online tasks developed are reported, in the context of the robustness of the automated scoring processes. Finally, technical and educational issues to be resolved in global projects of this nature are outlined.
