Mapping Tweetchat #caschat over a week

Using socioviz.net looked at the use of a particular weekly tweetchat hashtag #caschat over a one week period 16th March 2016 to 22nd March 2016. The chat happened on 22nd March 2016 discussing Robots in Teaching.

The table above (and the graph below) give an indication on the active use of the hashtag during the week, along with the level of engagement from others shown in the influence score.

 The above figure shows all those who used the hashtag or were referred to in tweets using the hashtag during the week. A large central group and smaller outlier groups.

Focusing of the central group, I would suggest there is different behaviours occurring. One of which  in the centre there is a central discussion very interconnected; apart from this there may be spun off conversations happening as well. The 'leaves' on the outside are mostly likely to people being mentioned but with some evidence that some then get involved.

Let’s Talk about Raspberry Pi 3. #BSW2016

Imagine this scenario: Sarah walks into the ICT suite, and sits down in front of a screen, keyboard and mouse and a few cables. She opens her bag and pulls out a small plastic box around the size of large match box and plugs in the cables, one each for the monitor, the keyboard, mouse and lastly the power leads to the box. One the screen after a few seconds the screen changes and she is ready to work on her coursework on the word-processor and do some searching, because this box has already connected to the wireless network.

The new Raspberry Pi 3 is exciting, but mainly because it is a Raspberry Pi and plays a huge part in what this means for the future of computing.

In the last few weeks, the scenario above took a giant step forward to being a reality with the release of Raspberry Pi 3 from the Raspberry Pi Foundation. A matchbox size computer for under £35 means that a truly personal computer is possible; one for each student or even as an alternative to shared PCs. The downloadable software used for Raspberry Pi includes the basic things most people need such as word-processing, spreadsheets, browsers, etc, and all for free.

Raspberry Pi has been around for four years now, but what puts the new Pi model a step ahead are two fundamental things:

1) Its wireless and Bluetooth connectivity are built into one for the first time

2) The processor is getting closer to that of laptops and desktop computers

Ok, so am I suggesting that schools throw out their current computers? No not for a moment.

When the time comes to renew them though, perhaps considering the advantages and disadvantages of a £30 computer instead or in the extreme scenario above, one £35 computer per student is worth considering.

The technical aspects alone are a good reason to make a Raspberry Pi 3 purchase, but in my opinion it would be the Raspberry Pi Foundation itself and it’s community that are the real advantage. The Foundation’s stated goals are “…to advance the education of adults and children, particularly in the field of computers, computer science and related subjects.”

The Foundation also owns the Code Club; a network of volunteer-led, after-school coding clubs which are committed to training teachers in computing and training on how to use Raspberry Pi through a two-day course called PiCademy.

The ace up their sleeve is that they have the support of a relatively large community of hobbyists who play with Raspberry Pi for their own fun and have a culture of sharing ideas, projects and providing support to each other. In my view this is the ‘secret sauce’; the teachers and hobbyists in the community provide and share resources very openly.

As an example, a new resource for using Raspberry Pi in science classes was recently made available and like most resources this has been produced by one or more hobbyists. One further example is the idea of PiJams; where anyone interested in finding out more or sharing what they are doing can come along and take part.

With these fantastic events in mind The University of Northampton is hosting the first Northamptonshire Raspberry Jam on the 16 April 2016. Register for free and share your knowledge or learn something new!
