KS3 Computing

Pupils should be taught to:

• • design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems

  • understand several key algorithms that reflect computational thinking; use logical reasoning to compare the utility of alternative algorithms for the same problem

  • use 2 or more programming languages, at least one of which is textual, to solve a variety of computational problems; make appropriate use of data structures; design and develop modular programs that use procedures or functions

  • understand simple Boolean logic and some of its uses in circuits and programming; understand how numbers can be represented in binary, and be able to carry out simple operations on binary numbers

  • understand the hardware and software components that make up computer systems, and how they communicate with one another and with other systems

  • understand how instructions are stored and executed within a computer system; understand how data of various types (including text, sounds and pictures) can be represented and manipulated digitally, in the form of binary digits

  • undertake creative projects that involve selecting, using, and combining multiple applications, preferably across a range of devices, to achieve challenging goals, including collecting and analysing data and meeting the needs of known users

  • create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability

  • understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct, and know how to report concerns
