Topic

Basic- Show Animation

Class

Year 7

Prior learning / place of lesson in scheme of work

Learn how to creating an animation, basic->show animation to display a series of images. We will be learning how to create a counter app using a forever loop, the input on shake, and show animation.

What the teacher needs to know / QuickStart Computing Glossary

  • Algorithm: An unambiguous set of rules or a precise step-by-step guide to solve a problem or achieve a particular objective.
  • Command: An instruction for the computer to execute, written in a particular programming language.
  • Hardware: The physical systems and components of digital devices; see also software.
  • Input: Data provided to a computer system, such as via a keyboard, mouse, microphone, camera or physical sensors.
  • Loop: A block of code repeated automatically under the programs control.
  • Output: The information produced by a computer system for its user, typically on a screen, through speakers or on a printer, but possibly through the control of motors in physical systems.
  • Programmable toys: Robots designed for children to use, accepting input, storing short sequences of simple instructions and moving according to this stored program.
  • Program: A stored set of instructions encoded in a language understood by the computer that does some form of computation, processing input and/or stored data to generate output.
  • Selection: A programming construct in which one section of code or another is executed depending on whether a particular condition is met.
  • 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.

Objectives

  • learn how to repeat code in the background forever
  • learn how to show a series of image frames on the LED screen, pausing the specified time after each frame
  • learn how to run code when the micro:bit is shaken; when running code in the web browser, moving the mouse quickly simulates shaking

Progression Pathways / Computational Thinking Framework

Algorithms

  • Uses diagrams to express solutions.(AB)
  • Uses logical reasoning to predict outputs, showing an awareness of inputs (AL)
  • Understands that iteration is the repetition of a process such as a loop (AL)
  • 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)

Hardware & Processing

  • Knows that computers collect data from various input devices, including sensors and application software (AB)

Communication Networks

  • Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns Understands how search engines rank search results (AL)

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
