Farewell to ICT or evolving ICT into Computing?
Phil Baggecode-it.co.uk
Lets keep being creative
• All pupils are responsible, competent, confident and creative users of information and communication technology
• select, use and combine a variety of software (including internet services) on a range of digital devices to accomplish given goals, including collecting, analysing, evaluating and presenting data and information.
New Computer Science POS
• design and write 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; generate appropriate inputs and predicted outputs to test programs
• use logical reasoning to explain how a simple algorithm works and to detect and correct errors in algorithms and programs

AlgorithmProblem Solving
We use our own rules all the time we just don’t realise it

QuestionsAsking Annoying
What do you do if someone gets hurt in
your school?
Towards a progression in algorithm Understanding
• Basic linear steps (logo & directions)• If else choices• Repetition (loops)• More complex rules
Optional
Programming
• Computational tools– Computational thinking• Steps• Loops (iteration)• Choice (selection)
– Decomposition– Debugging
How do we get there?
• Different approaches– Programming model• Characterised by game creation• Software driven (Logo Scratch Mindstorm etc)
– Algorithm model• Away from computers• Real life problems
Programming Model
Pluses• Pupils expect to use
computers in computing lessons
• Pupils learn computational skills to solve concrete problems
• Can use trial and error• In some areas like Logo
teachers can have pre-existing skills
Minuses• Problems are limited to
those you can solve by programming
Algorithm Model
Pluses• Wider interest than just
programming related problems
• Clear link to problem solving in general that has wider use than just computing
Minuses• Pupils enjoy using
computers
Need Both
• I teach computational skills through programming using Logo Scratch Python etc
• Extend into wider algorithmic problem solving once pupils have experienced elements of computational thinking using Scratch & Logo etc
• Cross over lesson Jam Sandwich Robot
Networks & Internet Search Engines
• 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
• describe how internet search engines find and store data; use search engines effectively; be discerning in evaluating digital content; respect individuals and intellectual property; use technology responsibly, securely and safely
Teaching Skills
• Facilitators not source of all knowledge• Collaborative not just individual• Promoting pupil problem solving strategies
(debugging)• Questioning first before solving• Avoiding negative attitude even if worried
personally (example)
Teaching Models
• Class Teacher• School specialist• Cluster specialist
