The old ICT curriculum was about digital use, in terms of the games industry, it's like someone being able to play the video game Angry Birds, but having no idea how to make Angry Birds. So the old ICT [curriculum] was, effectively, teaching kids how to read, but not how to write.

It's like a toddler being able to jump and land. He can do it without knowing any physics. But actually understanding why when you jump, you land – that's learning the physics. And computing is the equivalent.

Dr Andy SievewrightActon High School
We are really pushing the idea that our students, if they take on computing and they do it well, will be better learners. They will be more resilient, they will develop their computational thinking and deconstruction and reconstruction skills, which will help them in lots of different subject areas.

Prof Alan MycroftCambridge University
The language of the new draft computing curriculum for key stage 1, which includes phrases like "understand what algorithms are, how they are implemented as programs on digital devices" and "use logical reasoning to predict the behaviour of simple programs" could be intimidating for primary school teachers.

Locked-in Syndrome
A person with locked-in syndrome is totally paralyzed except perhaps being able to move an eyelid
They can see, hear and think but they cannot communicate back
Their intelligent mind is trapped inside a useless body

Could you write a book if you had locked-in syndrome?
Jean-Dominique Bauby did…
Describing what his life was like with locked-in syndrome
It is described as
“one of the greatest books of the century”
How did he do it?

The helper reads the alphabet a letter at a timeIs it A?
Is it B?
Is it C? etc
Blinking means yes, not blinking means no
The helper writes the letter down.
Then starts again with the next letter
A better way?

What are the problems?
How fast is that?
![Page 13: Get with the programme! Simon Humphreys National Coordinator Computing At School](https://reader035.vdocument.in/reader035/viewer/2022062408/56649e575503460f94b4f39b/html5/thumbnails/13.jpg)
How fast is it?
It is very slow
It takes on average 13 questions for every letter
At worst it takes 26 questions
![Page 14: Get with the programme! Simon Humphreys National Coordinator Computing At School](https://reader035.vdocument.in/reader035/viewer/2022062408/56649e575503460f94b4f39b/html5/thumbnails/14.jpg)
Winning at 20-Questions
Do you ask questions likeIs it Lady Gaga?
Is it Will Smith?
Is it Lara Croft?
Is it Gandhi?
Is it Gromit?
Is it Beyonce?
That would on average take billions of questions you have only 20!

Search Algorithms
We have looked at two different ways of searching for information
Two different algorithmsLinear search
One by one
Binary searchDivide and conquer
Halving search

Computers and People
Before you come up with solutions …you must make sure you understand the problem.That usually means understanding people as well as
computers.
Only then can you work on ways to improve things.
That is what computer science is about …thinking out of the box…doing things better… that couldn’t be done before… improving life for all … changing the future.

Computing at School
Simply a group of individuals, concerned about the state of computing education in our schools
Including: Teachers Industry (eg. Google, Microsoft) University academics (incl. CPHC, UKCRC) Members of exam board (eg. AQA) Members of professional societies (eg. BCS) Parents Local educational advisers Teacher trainers
Varied backgrounds, with common concerns
