MSc meets Micro:Bit

I have recently been teaching a module on Internet Programming on a MSc Computing programme (see related links), and was looking for a way to introduce a little bit of physical computing to finish of the module - micro:bits offer a route.

So a bit of context; most of the students on the module had first degrees in either networking or software engineering; so before they start the module they are competent in programming with Javascript, HTML, CSS and PHP. Therefore the module looked to develop new areas such as introductory blockchain,  virtual reality via the web (e.g. WebVR), using social media sources; but lastly looking at physical computing leading to an insight into the Internet of Things (IoT). As part of this last topic gaining some experience of programming and very simple networking was looked at using the micro:bit.

An activity was produced where:

• they, in pairs, initially replicate some code and work out how it worked;
• they then took the code and experimented with their own ideas.

In all cases they had to produce something that allowed doing something on one micro:bit, caused another micro:bit to do something in response.

Initially, javascript blocks (as above) were used and some students stuck with the graphical blocks, others moved into the text-based version. As far as the activity went it didn't matter; the main goals were to see the programming of a physical device via a web interface; to break a little mystique that it is as ways much harder to program physical devices and to get a bit of very simple networking going on.

Many of the students, started to investigate getting sounds to play on headphones and getting one micro:bit to trigger the other to play. One group went and started playing with python. 

Reflection bit - If I had similar, competent group again I would start this earlier; the level of engagement seemed high and the activities could then start developing towards IoT. Though, I admit to a bias for physical computing, it is appropriate in HE teaching; even using tools primarily designed for schools like the micro:bit.

Be an Unplugged Computing Artist

A recently released book Teaching Computing Unplugged in Primary Schools  edited by Helen Caldwell (University of Northampton) and Neil Smith (Open University) has a number of interesting chapters by authors who are passionate about how computing is taught in schools. The central theme is unplugged activities, without using computers, but still teach the fundamental of computational thinking.

Ok, confession time. I co-wrote, along with Katharine Childs (Code Club), Chapter 3 Artists so I am biased here, but I believe in the central theme of Unplugged Computing. Computing, and Computational Thinking in general,  is not just about programming and using a computer (though using computers and  programming are vitally important to Computing) but it is also about many other things including problem-solving, being creative and working collaboratively.

Chapter 3 is about linking these computational thinking ideas to produce visual art, by applying computing principles including  repetition, following and refining algorithms, and abstraction. The chapter also looks, how these links have already being made, with examples such Sol Le Witt where not all the work that was produced by the artist himself, but some by others following his written instructions - in other words an algorithm. An example activity is shown below (named after my son who was the first to play it).

Thomas’ Tangles

Exploring abstract patterns using randomness within an algorithm.

Using crayons, pencils or pens, we are going to follow an algorithm to create a random drawing. This could be done in pairs and you will need squared paper.

Person A: Rolls the dice and reads out the instructions.

Person B: Is the ‘robot' carrying out the instructions.

When the starting or central square is blocked and a new central square is needed the roles of A and B swap (so A is the ‘robot’ and B rolls the dice and reads out the instruction). The roles keep swapping.

Algorithm

Start from a random square – call it the centre square

Repeat until end of game

If die roll = 1

Roll die for number of moves

Check for blocks

If not blocked then

move die roll number of steps up the page

If die roll = 2

Roll die for number of moves

Check for blocks

If not blocked then

move die roll number of steps down the page

If die roll = 3

Roll die for number of moves

Check for blocks

If not blocked then

move die roll number of steps to the left

If die roll = 4

Roll die for number of moves

Check for blocks

If not blocked then

move die roll number of steps to the right

If die roll = 5

Roll die

If die = 1 change colour to Red

If die = 2 change colour to Blue

If die = 3 change colour to Black

If die = 4 change colour to Red

If die = 5 change colour to Orange

If die = 6 change colour to Yellow

If die roll = 6

Return to current centre square

Check for blocks:

If pathway blocked do not move then

reroll die

If number of spaces in the direction > die roll then

move until blocked

If all pathways blocked then

choose a new centre square

The other chapters make links with areas such as Robots, Musicians, Explorers, Magicians, Gamers, Cooks and Scientists.

waste as tool to inspire potential computing students

Originally posted as: http://computingnorthampton.blogspot.co.uk/2012/02/waste-as-tool-to-inspire-potential.html in 2012.

A recent article in the Northampton Herald and Post " How a university is using waste as tool to inspire students" by Lawrence John discusses the Junkbots project. 

"FUNNY looking robots called junkbots could be the key to encouraging more children across the county to become engineers, computer programmers or scientists.

One force which is driving this idea forward is the University of Northampton.

For the past few years, staff from its science and technology department have been going out to primary and secondary schools to spread the word that science is fun.

By working with schools, the university hopes to show pupils a different side to computing and hopefully raise their interest in what they can achieve" Lawrence John
