Cambridge IGCSE Physics 3rd Edition

New editions for examination from 2023. We are working towards endorsement by Cambridge Assessment International Education, so you can be confident this series supports the syllabus.These flexible resources have a skills development focus to help prepare the scientists of the future. Choose which components you need from our comprehensive series, comprising a coursebook, teacher's resource, workbook, practical workbook, and English language skills workbook and maths skills workbook (coming in 2022).Through extensive research, including lesson observations, teacher interviews and work with our online research community (the Cambridge Panel) these resources have been designed to meet specific challenges through targeted support and the creation of dedicated components that focus on specific skills areas. The series supports students learning science in English as a second language; learners who need more support with mathematical content in science; the development of essential practical skills; and the building of confidence with command terms and exam-style questions.

The maths skills workbook with digital access help learners to develop their maths skills in the context of the Cambridge IGCSE Physics syllabus. These skills are crosslinked to the coursebook to help students understand how to use them. Practice exercises provide opportunities for learners to practise each maths skill. To support students in acquiring these skills, the exercises gradually increase in complexity. Practice questions provide opportunities for students to practise their skills in an active learning format such as discussion opportunities and pair work. Exam-style questions give students the chance to apply the skills they have learnt in an exam-style context. In the last chapter, students will need to select which maths skills they ought to apply in different contexts, without the structure and guidance provided in each of the chapters, helping them become confident, independent learners.

Features
