Key stage 3
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 [for example, ones for sorting and searching]; use logical reasoning to compare the utility of alternative algorithms for the same problem
  • 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
Key stage 4
All pupils must have the opportunity to study aspects of information technology and computer science at sufficient depth to allow them to progress to higher levels of study or to a professional career. Pupils should be taught to:
  • develop their capability, creativity and knowledge in computer science, digital media and information technology
  • develop and apply their analytic, problem-solving, design, and computational thinking skills
  • understand how changes in technology affect safety, including new ways to protect their online privacy and identity, and how to report a range of concerns

Description

A deeper look at Python for intermediate or advanced coders in upper middle or high school. This course is tailored for students who have completed introductory visual programming courses on Tynker and want to advance to text programming in Python. Students will start with simple input-output statements and conditional logic, then progress to using more complex data structures to build algorithms. With hands-on coding practice, students learn to design, build, and debug programs – skills that any programmer needs to solve real-world problems. Students who successfully complete this lesson plan will demonstrate a strong mastery of Python syntax and functionality, as well as the ability to independently solve advanced coding problems.
