Years 9 and 10
Digital project: Representation of data
Summary of task
Students created a website using Cascading Style Sheets (CSS) to control visual elements of their web page, and developed an understanding of why data needed to be compressed and separated from presentation. They used Unicode to create a greeting and compressed their chosen data type at various compression rates. They explained the differences in terms of quality, and evaluated their solutions.
By the end of Year 10, students explain the control and management of networked digital systems and the security implications of the interaction between hardware, software and users. They explain simple data compression, and why content data are separated from presentation. Students plan and manage digital projects using an iterative approach. They define and decompose complex problems in terms of functional and non-functional requirements.
Students design and evaluate user experiences and algorithms. They design and implement modular programs, including an object-oriented program, using algorithms and data structures involving modular functions that reflect the relationships of real-world data and data entities. They take account of privacy and security requirements when selecting and validating data. Students test and predict results and implement digital solutions. They evaluate information systems and their solutions in terms of risk, sustainability and potential for innovation and enterprise. They share and collaborate online, establishing protocols for the use, transmission and maintenance of data and projects.
