Cambridge IGCSE Biology 4th Edition

New editions for examination from 2023. With endorsement from Cambridge Assessment International Education you can be confident this series fully 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. 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 and fluency with command terms and exam-style questions.

Research shows that English language skills are the single biggest challenge to students accessing international science. Language should never be a barrier to a student’s learning journey. Science can be a particular challenge because of specific technical vocabulary and sentence structures. This English language skills workbook with digital access helps learners to develop their language skills in the context of the Cambridge IGCSE™ Biology syllabus. The workbook contains exercises for each chapter that combine the science content with relevant language skills. Exercises develop learners’ language enabling learners to practise using key vocabulary in different ways, such as through the provision of sentence stems for students to use in their own writing; through speaking and listening with peers, or group work. Activities range from practising using expressions of contrast in the context of animal and plant cells, to re-writing an experimental method to observe the effect of pectinase on orange pulp as a report using the passive voice.

Features

• Wide-ranging exercises and activities reinforce syllabus content whilst providing structured support to develop relevant language skills
• ‘Language Tips’, such as, providing extra information to aid memory of key terms, or suggestions of synonyms or alternative ways of expressing ideas help learners to build linguistic confidence
• A glossary of the words and definitions from the ‘Key Words’ feature boxes in context throughout each chapter is found at the back of the book as a quick reference tool
• Scientific vocabulary, academic vocabulary and everyday vocabulary that might be challenging (e.g. work, table) is highlighted and defined in ‘Key Terms’ boxes in context throughout the workbook as a quick, reassuring reference point
• ‘Language Focus’ feature provides a background linguistic explanation of the relevant skills in context throughout the text, giving you confidence you are using the right skills.
