Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to manipulate an image through fade out, fade out to gradually decrease the LED screen brightness until the LED lights are turned off. We will be learning how to fade an image using simple commands, such as image create image, image show image, LED fade out, basic pause, and fade in.

What the teacher needs to know/QuickStart Computing Glossary

  • Algorithm: An unambiguous set of rules or a precise step-bystep guide to solve a problem or achieve a particular objective.
  • Computational thinking: Thinking about systems or problems in a way that allows computer systems to be used to model or solve these.
  • Hardware: The physical systems and components of digital devices; see also software.
  • Programmable toys: Robots designed for children to use, accepting input, storing short sequences of simple instructions and moving according to this stored program.
  • Script: A computer program typically executed one line at a time through an interpreter, such as the instructions for a Scratch character.
  • Sequence: To place program instructions in order, with each executed one after the other.
  • Simulation: Using a computer to model the state and behaviour of real-world (or imaginary) systems, including physical or social systems; an integral part of most computer games.

Progression Pathways / Computational Thinking Framework

Algorithms

  • Uses diagrams to express solutions.(AB)
  • Represents solutions using a structured notation (AL) (AB)

Programming & Development

  • Creates programs that implement algorithms to achieve given goals (AL)
  • Selects the appropriate data types(AL) (AB)

Information Technology

  • Collects, organizes, and presents data and information in digital content (AB)
  • Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution (EV)
  • Recognises ethical issues surrounding the application of information technology beyond school.

Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
