Deeper Learning Objectives Content- Subject Learning Objectives Capacity Stretching Objectives • To understand that computers are deterministic: do what they’re told and only what they’re told Analyse, question, notice problems • To understand how to solve problems with decomposition: breaking the problem down into smaller pieces Don’t give up, empathise, discuss • To develop persistence in problem solving Make links, explain, adapt, imagine • To develop collaboration skills and work together Evaluate learning, communicate • To understand the influence of Computer Science on the future Plan, explore, identify Cooperate, collaborate
Can you remember? • What deterministic means Computers do what they’re programmed to do and only what they’re programmed to do • What symbols you used to change the order of operation of your instructions? ( ) • The language is based on another subject that uses () symbols. What do you think the other subject is? Mathematics
Remember! Persistence! • If you don’t get the picture you describe – Did the computer draw it wrong? х – Did you describe it to the computer wrong? • What do you do if you don’t get what you want? 1. Check your instructions 2. See where they might be wrong 3. Think about a logical next step 4. Try the next step
Geom. Lab • Has two special functions that apply to pictures: rot and flip • To make the rot and flip functions work on a picture you give the functions the picture to work on inside ( ) symbols • In lower window type “rot (man)” and press go • In lower window type “rott (man)” and press go – This is an error. What do you think it means? – Check your instruction – See where it might be wrong – Think : Oh, I meant to type “man” – Try again
Group Work • You’re going to instruct the computer to create this picture. • You need to break it down (decomposition) do it a little piece at a time, testing at each step • Build up a solution
Geom. Lab Instructions Your Turn: • man, woman, tree, star • rot () and flip () Open the Geom. Lab_Worksheet for more help; Try to finish Exercise 2 today – Can you figure out what they do? – Test and see • Special operators $ & ( ) Think GRID!! If you’re Is blank an object? really Arguments to rotreally and flip can be stuck, complex pictures: rot (man & tree) press here for a hint.
Everyone Back Together • Chance to consider your future • Consider that there are subjects, careers, and things to discover that you’ve never even though of • Computer scientists, just like chemists, physicists, and biologists are changing the future • You can, too! Think big! Be brave!
Computing is not ICT • Teaches how to be an effective author of computational tools • Teaches how to be a thoughtful and effective user of technological tools • Key concepts: • Use of tools: – Languages, algorithms, machines, models – In everyday life (phones, WWW) – Data representation, organisation, storage, transmission – In business (finance, marketing, manufacturing) – Communication and coordination – Abstraction and design – In science (data collection, analysis, medicine)
Geography • ICT – Collecting data about air quality each day for a year – Analyse the changes using a spreadsheet – Write a report for the council to recommend a change of traffic flow • CS – Create a simulation of how air quality is affected by external factors – Use the data collected as input to the model – Predict what will happen in the next 5 years if traffic flow is changed and if traffic flow is not changed
Chemistry or Physics • ICT – Set up and perform experiment, collect fast-frame video – Compare frames of video to see interaction of entities (remember someone probably had to create the software to let you compare the frames) – One experiment, one data collection, one conclusion – May be expensive and dangerous • CS – Create a simulation of how molecules interact – Apply model with different formulas – Predict effects of interaction of physical entities or chemical reactions in very large or small scale – Multiple experiments, multiple data, many conditions, may be cheaper and safer

Plenary • Who did decomposition today? • How many people had errors? • Who could fix some of their own errors? • Who helped another person fix errors? • Who learned about new uses for computer science skills?
