The Time I went to Picademy...

Having heard about this amazingly inexpensive and useful computer called the Raspberry Pi about 2 years ago, I finally decided to undertake some formal training in order to fully understand exactly what it was capable of doing, especially in my classroom. Enter Picademy!

I have always loved Twitter as a means of finding out what other professionals are doing to engage their pupils, but one day I caught a glimpse of a hashtag that really interested me... #Picademy. I follow quite a few Raspberry Pi enthusiasts so #Picademy seemed to be popping up everywhere! From a small amount of research, I discovered that it was a fantastic two days of CPD for educators who wanted to extend and develop their knowledge of computing and the new curriculum through the use of my new favourite 'toy', the Raspberry Pi.

I completed the application process to join Picademy #8 which included writing a blog post on 'Being a 21st Century Teacher'. I then had a long wait ahead of me to hear whether I would be selected to attend. I regularly headed back to Twitter to discover a whole host of amazing Picademy applicants, including David Saunders and (past Picademy attendee) Cat Lamin. Through my discussions with these two technology gurus, I was starting to get very excited about attending. So I think it's fair to say that I was bouncing off the walls upon receiving my acceptance email. The beautiful thing about Picademy is the community spirit. It's like one big family of incredibly creative people and I'm very happy to finally be a part of it.

So what did I get up to in two days of Picademy-ing... In a very small nutshell, the first day consisted of workshops with various experts, some of which were from the amazing community that I just mentioned! The final day was our own to take what we had learned and turn it into a Raspberry Pi project of our choosing.

DAY ONE

According to sonic-pi.net, Sonic Pi is 'audible computing'. Sounds intriguing, huh? A more detailed description is also provided on their website:

I had heard of Sonic Pi before Picademy but hadn't really seen exactly what it could do until the seriously brilliant Sam Aaron conducted his workshop with us. It's just fantastic to see coding being seen as an art form, and Sam is incredibly passionate about its use! And you can't help but agree with him.

Sonic Pi's nice and simple user interface

He took us through a thorough demonstration of what Sonic Pi could do, starting with three basic commands: 'sample', 'sleep' and 'play'. With these three commands in hand, Sam says you can start creating all kinds of music immediately, and the best thing to do next is to play around and see what you can do! We were then shown some more advanced tricks up Sonic Pi's sleeve, like loops and even live loops. The latter being when you can actually perform a piece and tweak it on the fly! But it didn't stop there... You can control Minecraft with Sonic Pi! More on that on day 2...

Sonic Pi is a beautifully simple, but powerful piece of software from a passionate creator. I will definitely be taking this back to school and bringing music alive through our computing curriculum.

Every child's favourite video game character hasn't gone unnoticed by the Raspberry Pi. A version has been ported to the Pi, and while it isn't the 'full-fat' PC version, you have the wonderful opportunity to hack it to pieces! Martin O'Hanlon, co-author of 'Adventures in Minecraft' (get it!), showed us how to do just that using the Python programming language.

Picademy rocks!

While O'Hanlon's book takes you through a whole range of Minecraft hacks and activities, we focused on some 'simple' elements: typing a chat message on screen (see image above); identifying Steve's location, and then changing it; identifying a particular block, and then moving a block to a different location. We achieved all of this by completing a couple of tasks (click the titles for links to GitHub code):

• Don't Look Down - throwing Steve into the air by finding his current location, then changing the y coordinate value.
• Duplicator - copying the block that Steve is standing on and placing it on top of his head. We did this by identifying the location and type of block beneath his feet, then adding that same block type to the location above his head.
• Walk on Air - placing blocks beneath Steve's feet so he could 'walk on air' by looping the placement of a diamond block in the location under Steve's feet.

Martin has created a very handy Minecraft worksheet which goes through some of these tasks and a few more to boot. After completing these tasks, Martin challenged us to create a Rainbow Bridge based on the Walk on Air project. I actually shocked myself by completing it! My Rainbow Bridge code:

Three of the first day workshops revolved around physical computing. We learned about the Pibrella, the PiCamera and using the Pi's GPIO pins to attach LEDs. Ben Nuttall had the job of showing us how to setup and use the PiCamera with the Raspberry Pi.

Below are the slides from Ben's presentation:

Picademy - Python picamera workshop from bennuttall

I have already done a little time lapse photography with the Picamera but I am looking forward to doing some more with the children at school. Here is a time lapse video of my school's Summer Fayre last year:

Big Les Pounder walked us through attaching a Pibrella to our Raspberry Pi. This cool little board sits on top of the Pi and consists of a button, three traffic light coloured LEDs and a buzzer for you to interact with. Les also showed us how to add additional components to the Pibrella, like a motor! We basically followed this tutorial on the Raspberry Pi website.

Lastly on day one, Clive Beale showed us how to use python to turn on an LED attached to the Raspberry Pi's GPIO pins. He also had one of the best props I've ever seen for demonstrating this too... I really wanted to take them home!

Land of the Giants?

Using the GPIO on the Raspberry Pi is what this amazing little machine is all about. Being able to turn an LED on and off seems so simple but it completely opens the doors to a wealth of other projects that can gradually increase in complexity. Instead of LEDs, attach motors and you have a drivable vehicle...

Look ma, no resistors!

So that was a whirlwind tour through day one... But that was only the beginning! Day two promised to be just as exciting.

Back at the hotel after a looooooong first day!

DAY TWO

As I said at the beginning, day two was generally about being let loose on all the hardware to create an interesting project. Our experts were on hand to impart any relevant knowledge (as well as irrelevant!) to assist us in our quests. At first, I wasn't very sure what I wanted to do. Dave Honess gave a few of us a quick demonstration of Astro Pi, a board that sits on top of the Raspberry Pi and is full of sensors that will soon be making the long journey to the ISS with Major Tim Peake.

Astro Pi in all its glory

As exciting as the Astro Pi was, I finally decided to do something with Sonic Pi and Minecraft. I was so impressed with Sam Aaron and Sonic Pi on day one that I felt I had to dig a little deeper with it. With the help of James Robinson, Sam and fellow Picademian, Alex Young, we set about exploring how we could incorporate the use of coded music into the phenomenon that is Minecraft.

Introducing the Sonic Minecraft Keyboard!

Alex and I thought it would be really cool if different pieces of music played when Steve stood on different terrains. If Steve was taking a walk in the desert, a summer time tune could play. Alternatively, when he was hiking through the arctic lands, a chilly winter theme would be heard. This would allow for dramatic storytelling to take place in the Minecraft world. Imagine Steve walking into a dark, scary cave just as a haunting piece of music begins to play...

Unfortunately, we didn't quite get that far! However, we did create a 'keyboard' to test different sample sounds that worked a treat. The completed code can be found here.

At the end of the second day, all attendees had the opportunity to share their projects to the group. When I said that the Picademy community is full of creative people, after watching all the presentations, I was definitely not wrong! I am well and truly honoured to be part of the Raspberry Pi Certified Educators family. Well done, everyone!

Picademy #8

Uni of Greenwich Professional Development Day

Tomorrow I'll be delivering a 'Professional Development Day' for a group of PGCE students from the University of Greenwich. I will be informing them about the new computing curriculum and showing examples of best practice through my school's use of technology.

I am very much looking forward to seeing what the new breed of teacher already knows about computing, particularly as they only know the new curriculum. It shouldn't surprise me to find that a generous number of them are more 'tech savvy' than myself...

The plan for tomorrow will be to spend about 20 minutes discussing the new curriculum and the future of education. I will then spend a generous amount of time on a range of resources that we use in school - approximately 15 minutes each.

Planned resources:

• iPad apps for coding: Bee-Bot, Daisy the Dinosaur, Kodable, Scratch Jr and Hopscotch
• Other iPad apps: Explain Everything and Book Creator
• MinecraftEDU
• Scratch (will probably go through my coordinates lesson)
• MaKey MaKey, Python and Raspberry Pi

Below is a copy of tomorrow's Prezi:

Coding with a Positive Message!

I recently discovered some fantastic printable Scratch coding blocks and thought they would be great for some CSunplugged work! They are available to download here.

This evening I had a little idea. What if you could take some of these Scratch blocks and use them to create a positive message of encouragement for your pupils? I decided to give it a try, and this is what I came up with... while True:

This is a nice message that helps children understand a tiny bit of technical vocabulary around coding, but also gives them a useful message about never giving up! It reminds them that they may not be successful straight away, and that if that is the case, they should TRY AGAIN and work harder to reach their goal!

I wonder what other positive messages can be created using these Scratch blocks? I'd love to see what others can create!

Using Scratch in Other Areas of the Curriculum

I have been using Scratch for a couple of years now, and while I'm definitely not a pro by any stretch of the imagination, I have found a couple of different ways to incorporate it into other areas of learning. The reason for this is the children I have worked with have always found it very engaging, even if a tad challenging at times (what's wrong with that?!)

One obvious link to computing is mathematics.

Coordinates

Here is a Scratch project I created for a coordinates lesson that I taught with some more able Year 5 children about a year ago. To see inside the project click here.

The idea was to get the children to create a variety of shapes in any of the four quadrants on screen. As you can see from the image below, all the children had to do was change the x and y values in the blue 'motion' blocks. Remember, this was a maths lesson and not a computing lesson. I tried to take away as much as possible from the computing side of things. The most they had to do was know to take away one 'wait' and 'go to...' block to create a triangle (one less side).

The children really enjoyed doing this activity. It was much more interesting and engaging than completing a similar task in their maths books!

But don't worry if you are not too familiar with Scratch at the moment! You will probably find something great to use in your lessons by using the search function on the site. There are lots of clever people within the Scratch community and they have probably already created something special just for you ;)
