Why teach coding?

Why teach coding?

2
It teaches you to think

• I think everyone should
• learn how to program
• a computer, because
• it teaches you
• how to think.
• Steve Jobs, 1996

KS1 Computing

• understand what algorithms are how they are
  implemented as programs on digital devices and
  that programs execute by following precise and
  unambiguous instructions
• create and debug simple programs
• use logical reasoning to predict the behaviour of
  simple programs
• use technology purposefully to create, organise,
  store, manipulate and retrieve digital content
• recognise common uses of information technology
  beyond school
• use technology safely and respectfully, keeping
  personal information private identify where to
  go for help and support when they have concerns
  about content or contact on the internet or other
  online technologies.

7
KS1 Computing - simplified

• Algorithms, programs and instructions
• Create and debug simple programs
• Logical prediction
• ICT
• eSafety
• Awareness of ICT beyond the classroom

8
KS2 Computing

• design, write and debug programs that accomplish
  specific goals, including controlling or
  simulating physical systems solve problems by
  decomposing them into smaller parts
• use sequence, selection, and repetition in
  programs work with variables and various forms
  of input and output
• use logical reasoning to explain how some simple
  algorithms work and to detect and correct errors
  in algorithms and programs
• understand computer networks including the
  internet how they can provide multiple services,
  such as the world wide web and the opportunities
  they offer for communication and collaboration
• use search technologies effectively, appreciate
  how results are selected and ranked, and be
  discerning in evaluating digital content
• select, use and combine a variety of software
  (including internet services) on a range of
  digital devices to design and create a range of
  programs, systems and content that accomplish
  given goals, including collecting, analysing,
  evaluating and presenting data and information
• use technology safely, respectfully and
  responsibly recognise acceptable/ unacceptable
  behaviour identify a range of ways to report
  concerns about content and contact.

KS2 Computing - simplified

• Design, write debug solutions. Simulate or
  control systems. Decompose problems
• Sequence, selection, repetition, variables,
  inputs outputs
• Logical reasoning, explain algorithms, detect
  correct errors

• Understand use computer networks
• Understand use search technologies
• ICT
• eSafety
• Be discerning with content

Algorithms

Algorithms

• Set of steps/rules to solve a problem
• Explanation changes with KS
• Chocolate biscuit robot game

Decomposition
15
Decomposition

• Solving any complex problem in life requires
  decomposition
• Creating a program that has more than one moving
  part, or more than a couple of simple steps
  requires decomposition
• Similar to planning a story elements not just
  steps
• Analyse this game and break it down into parts.
  What happens at the start?
• What are the elements in the game? What are the
  rules that govern it?
• bit.ly/fruitcode
• Sentence starters When, If, After, At the start

Decomposition
17
Selection
18
Selection

• Most programs need to change what they do in
  response to certain things happening
• E.g. if two objects collide a game may end

19
Debugging logical reasoning
20
Debugging logical reasoning

• use logical reasoning to explain how some simple
  algorithms work and to detect and correct errors
  in algorithms and programs
• Stepping through a solution to see if it works,
  or where it fails.

21
Delivering computing

• Teaching approach
• Scheme of Work/Learning
• Resources
• Try it yourself
• Teach assess concepts 'offline
• Give learners an audience for their creations
• Teach key concepts not software
