CAS Conference 2014 – Introduction to TouchDevelop Workshop

blog by Simon Johnson – Microsoft Innovative Expert Educator and Wolves supporter


Last week was the 6th annual Computing At School (CAS) National Conference. The conference, which was attended by more that 300 delegates, provided an opportunity for teachers to find out about the new curriculum. It also gave teachers the chance to meet and learn from other experienced educators about how to introduce computer science in the classroom.

As well as attending a number of inspiring and thought provoking workshops, I was asked to deliver a workshop of my own on behalf of Microsoft on how to use TouchDevelop to support the new Computing Curriculum. I can honestly say it felt an honour to be delivering a workshop along side the likes of Paul Curzon, Mark Dorling and Phil Gardner (to name but a few). It was also great to chat with other educators about how they plan to and, in some cases, how they are already using TouchDevelop to support the delivery of the new curriculum.

Unfortunately, due to reasons out of my control, not everyone was able to attend. This was a little disappointing, especially given the size of the computer labs. However, at the request of those who were unable make the workshop, below is attached a brief synopsis of the workshop along with resources used in the session. If you have any further questions about the resources in this session, or want to find out more about TouchDevelop, please don't hesitate to ask!

What is TouchDevelop?

TouchDevelop is an online app creation tool from Microsoft Research. Originally designed to develop Windows Phone 7 apps, the TouchDevelop Web App now allows you to develop Windows Store apps suitable for Windows 8 touch screen devices and runs on iPad, iPhone, Android, PC, Mac, Linux. There is also a dedicated TouchDevelop app on the Windows Phone 8.   

Why use TouchDevelop?

No installation required

· HTML 5 based so all you need is a web enabled device and an up-to-date web browser (No installation or plugins needed)

Visual programming environment

· Students aren't snarled up with syntax

Works on a variety devices

· Supported by a number of platforms (Windows, Android, iOS) and majority of web browsers (Internet Explorer, Safari and Chrome)

Bridges the gap

· Bridges the gap between BYOB programming environments (such as Scratch and App Inventor) and higher level languages (such as C++, Java and Python etc.)

Cloud based

• Anywhere / anytime learning

• Students have a global audience for their work


• Students can share their apps with a community of other developers and get feedback on their work

Encourages Indie game development

• Looks great on a student's C.V. - especially if the student has published their app to the Windows / Android app store

Workshop Synopsis

I started by introducing TouchDevelop and explaining the benefits of using TouchDevelop in the classroom. I then directed delegates to the TouchDevelop Web App and demonstrated how to get started.

I followed this with a simple (step-by-step) tutorial using the Turtle library in TouchDevelop. The turtle library is a great tool for introducing students to algorithms. It's also great for introducing iteration as well as discussing the benefits of optimizing code.

Once everyone had got to grips with the turtle library, I challenged them to try out some of the tutorials (below).
