Digital Technologies: Years 3 – 4 Student Workbook is an excellent resource for teaching an in-depth understanding of the Middle Primary Years V9 Digital Technology curriculum. The book is comprised of four sections: Section One: Digital Systems and Devices explores the evolution of digital systems over time, how computers work, why they are important and examines peripheral devices and their everyday uses. Section Two: Data on Computers explores the concept of data, examining digital data, and the various ways it is can be collected and represented. Section Three: Problem Solving with Algorithms explores how digital systems are programmed with step-by-step instructions to help solve problems and complete tasks. It then explores advanced algorithms using branching decision trees and provides online examples of how algorithms are created. Section Four: Information Systems and Ethics investigates the safe use of the internet and explores its role and functions, with a focus on ‘netiquette’ and ethics. Through an array of digital learning ideas and hands-on activities/worksheets, as well as reflection tools, students gain a thorough understanding of Digital Technology covering the Year 3/4 Curriculum Outcomes. The tasks have cross-curricular links to subject areas such as Health and Physical Education, English, Science and HASS, as well as Cross-Curricular Priorities such as Aboriginal and Torres Strait Islander Histories and Cultures and Sustainability.
