Gearing up for remote workshops

As our partner primary schools well know, the sharp end of NUSTEM starts with in-school workshops. We do many other things, but workshops are a key part of us meeting and working with schools and teachers, showcasing how we think practical investigation and careers ideas can be incorporated into science lessons, and prompting dialogue to help us understand what schools need.

Obviously, this is all a bit challenging if we can’t, well, go into schools.

In the run-up to the summer holiday Joe and Jonathan threw themselves into trying to work out how remotely-delivered NUSTEM workshops might work. Thanks to the sterling efforts of our fabulous partner schools we almost managed to pilot our thinking, only a completely unrelated last-minute disaster scuppering everything. But we’ll be back at it almost as soon as schools return next month. Along the way we’ve faced a host of challenges, some expected but many surprisingly subtle.

Over the summer we’re waiting for some equipment deliveries (we… er… broke some kit while testing it. Ahem.). We’ve also had discussions with a range of organisations facing similar challenges. It looks like we might be getting together with others for something of an online symposium / share what you know / learn from our mistakes session, in the second half of September. Drop us an email and we’ll keep you posted.

Without wanting to bore you with the details (I mean, who really wants to know about our measurements of different video streaming platform latency averages?), a sketch summary goes something like this:

We’re aiming to replicate key aspects of our conventional classroom workshops as closely as possible, as a starting point, in particular we want to develop workshops that still feel personal and allow us to interact and react to the children in the classroom, and that promote ‘hands on, minds on’ learning.  We’re also interested in the situation where workshop participants share a physical space (ie. their classroom), and the presenter is remote. This is quite different from the typical Zoom/Teams/Google Meet arrangement, where each participant is in a separate physical space.

In our partner schools, we’ve found the class PC (the one connected to a data projector, displaying at the front of the class) typically does not have a microphone or camera. We chose early on to adopt a policy of not asking schools to replug any IT equipment, so for the presenter to follow what’s happening in the classroom a second channel is required. That is, our basic setup is:

  • Presenter delivers to class PC, projected onto whiteboard.
  • Roving iPad/laptop in classroom, showing proceedings back to the presenter.

These devices have to be in separate video chats, or there’s audio ring-around/howl. The only work-around for that would be to manage microphones manually in the classroom, and we don’t want to impose that burden on our schools… so we have to handle audio at our end.

Meanwhile, schools vary in their IT policies, and the extent to which the software fit on their PCs/laptops/tablets matches those policies. So whatever we do has to be platform-agnostic: it has to work across Zoom, Teams, Meet, and others. We want to be able to deliver fluid, high-quality audio and video into any of these systems.

…aaaand whatever we build has to be useable for us, such that our presenters can focus on the content and participants, not on working the tech.

We’ve explored a bunch of other aspects, but this is already getting long and we’ll have to save a full write-up for another day/paper/booklet. Last week we ordered a bunch of equipment which – we hope – will allow us to do what we need in a relatively simple way. If we’ve guessed right, the technology will start to fade into the background and we can lift our gaze to the questions which are actually interesting:

  • How do primary-age children perceive workshops delivered via streaming video? Does it seem natural to them, or forced? Does it come across as ‘like TV, but worse?’, and could we address that by making our streams more or less like broadcast?
  • How much do our workshop structures and content need to be adjusted to accommodate remote delivery? Is the old model still appropriate, or is there something better?
  • Is the workload manageable for teachers and assistants in the classroom? How much can we involved them in the delivery of the workshop?
  • How does it feel for our presenters? What support and development can we extend to ease their transition and help them build confidence?
  • What opportunities can we identify from this? It’s theoretically easier to include a working scientist or engineer in a school workshop if they can join from their (home?) office rather than have to travel to the school. Is that a good thing?
  • Can (and should) we deliver to multiple classes at once? How about multiple schools?
  • Do we present demonstrations ‘live’, or play-in prerecords? Does that judgement change if we’re delivering an assembly rather than an in-class workshop?

We’ve learned a lot to this point, but the really important work lies ahead of us. We’re also watching what other people are up to, and trying to work out where their thinking improves on ours. Behind-the-scenes, there’s really gratifying sharing and collaboration going on across the science communication sector, with individuals, institutions and umbrella organisations trying to help each other out as best we can. If you’re part of this world and don’t feel you’re part of those conversations, drop us a line and we’ll try to loop you in.

(Raspberry) Pioneers, Bright Ideas: opportunities for secondary students

The lovely people at the Raspberry Pi Foundation – the folks who spend the money made from selling all those zillions of credit-card sized computers – have launched their programme for 12-15 year-olds, Pioneers. The idea is: a group of friends gets together, they find a mentor (an adult who can help them along, and also sign things on their behalf), then they take part in a mass group challenge. There’s a fresh challenge every three months, and the first one’s just been announced; see the film above for details, but the basic idea is, “Use technology to make us laugh.”

There are prizes for the best japes, hence there’s a submission deadline of 22nd March 2017. The plan is also that the challenges produce starting points and examples for a huge range of projects, all using digital technology, so everyone can learn from everybody else. Or something like that.

Interested? There are more details at the Pioneers web page, along with links to register a team, information for mentors, suggestions for starting points, and so on.

We’ve been waiting keenly to see what the Pi Foundation ‘do’ at secondary to follow on from their Code Club offer for primary ages, and we look forward to seeing how Pioneers develops. We’re particularly looking forward to laughing at some of the creations from this first challenge.

Shell Bright Ideas Challenge

Meanwhile, if you’re after a more traditional sort of competition, Shell UK are again running their Bright Ideas Challenge. Unsurprisingly, their challenges are based around energy. Here’s the glossy introductory film:

There are a range of ‘what-if…?’ future technology challenges, along with resources for participants and teachers and further films to introduce each of the challenges, on the project website. Submissions are due by 21st April 2017.

Here at Think Physics orbiting world headquarters we have mixed feelings about competitions for secondary students. They certainly can be of value to students, but there are so many of them it’s hard to know which are worth investing time in. In this case, project resources look comprehensive and well-presented, so it should be straightforward to take a look and see if Bright Ideas seems a good fit for you and your students.

If your school took part in Bright Ideas last year, leave a comment below or drop us a line to let us know how it went, and whether you’d do it again.

Astronauts, sports scholarships, the web, deforestation, and the power of unexpected connections

Here’s a delightful little story from web developer Sarah Mei, posted on Twitter. It starts out being about American university sports scholarships, but heads off in directions you’re really not going to expect.

We all assume, when we’re in school, that we’re going to have ‘a career’, that it’s going to make sense, and that we can map out roughly how it’s going to go. For some people that’s absolutely true, but for many (most?) of us, our lives take twists and turns we’d never have predicted. Some of us rather like it that way, even if we don’t have stories quite as good as this.

Tip of the hat to Elin Roberts for the link.

New competition for secondaries: Microsoft STEM Student Challenge

I know, I know – the education world is awash with competitions. Stick with it, this one’s a little different and it looks like it could be genuinely fun… and also smart.

Microsoft Research in Cambridge are running a competition which builds on students’ knowledge of STEM subjects, but also on their research skills and particularly their imaginations. The challenge goes:

  1. Pick one of these themes:
    1. Artificial intelligence and virtual reality
    2. Data security
    3. Healthcare
  2. Now come up with an original technology idea which you think could exist in that field in 20 years’ time.
  3. Make a short film which showcases your idea.
  4. Submit the film.

Prizes and the experience for finalists look good, and there’s a clear information pack available at the challenge website. The competition’s open to teams of 4-6 students, in years 8-10.

What I like about this particular competition is that the central conceit is both accessible and clever. We all dream about what the future might bring, this is simply asking you to commit to (and describe) a specific vision. In doing so, you’ll have take what you know about STEM subjects and extrapolate that thinking twenty years into the future. This isn’t some well-intentioned-but-ham-fisted attempt to ‘make science relevant to our everyday lives,’ it’s an invitation to students to find the relevance for themselves. That’s clever.

Also, I’m a sucker for a schools’ STEM film competition.

The only thing I find a little surprising is that there’s no category for primary-age entrants. A pity for them, but also for the judges, who’ll miss out on genius like this. Ah well, maybe next year?

Anyway – secondaries: get your cameras out, sharpen your pencils, brush up on your tech skills and prop-making, and show us how the world’s going to be in 2037. Registration deadline is 8th December, with entries due by 10th February 2017.

Ooh, one last bit of advice: with our Technology Wishing Well we’ve collected about 800 wishes for future tech, from Maker Faire UK and Big Bang North-East. We haven’t yet done a proper analysis, but as a quick hint: lots of people want a flying robot dog which does their homework and tidies their room. Which would indeed be awesome, but you might not be the only entrants to suggest such a thing to this competition.

 

Introducing the Technology Wishing Well for Maker Faire UK 2016

At Maker Faire UK last year Think Physics had two stands; a wall of light boxes, and a magnificent harmonic pendulum display which, slightly embarrassingly, I still haven’t written up. Hoping to avoid a similar mistake this time around, I should introduce you to this year’s new installation: the Technology Wishing Well.

WishingWell v1

Er… yeah, that’s a bit of a mess. What you’re looking at is a corner of my desk, on which you can see the black disc of a small turntable. That’s part of the light box installation, repurposed shamelessly (hey, I’m allowed to steal from myself, right?). On the turntable are a couple of LED lights. The green one is pointing upwards, the red one fell over and is pointed off to one side.

Left of frame is a retort stand, holding a Raspberry Pi (Pi 3! Woohoo!) and a PiCamera, which as far as I can tell is a mobile phone camera module on the end of a stubby little cable. The Pi is driving the big monitor upper right, and the window in the top corner is showing… what, exactly?

OK, so I’ve written a little Python code which does the following:

  1. Grabs a picture from the camera.
  2. Takes all the stuff which is ‘dark’ in that image, and turns it transparent.
  3. Adds the result to the previous image.
  4. Repeat.

So, as the turntable turns the green light smears into a ring, and the fallen-over red light smears into a… weird red blobby donut thing. My python code is appallingly slow, but conveniently the result is mesmerising to watch as it gradually builds up. Which is a relief, because we’ve committed to building this thing and there’s no turning back now.

The plan is to build a big one of these, so the current turntables can sit on the big turntable, and then we’ve made a giant light-powered video Spirograph-like-thing. We’re also planning to build little gizmos which move lights around, or change their colour over time, or … well, you’ll have to wait and see. You’ll also be able to make your own lights and toss them onto the turntable disc to add to the artwork as it develops, which is where the whole ‘wishing well’ idea comes in.

There’s lots to do before Maker Faire, but right now I’m just excited (and a little relieved) to see something on a screen rather than in my imagination. This moment’s been a long time coming.

The header image shows the first run of the software – here’s detail of the second, just before the Pi crashed hard. Umm… I should probably look into what caused that.

Tech wishing well second run

Ohbot on Kickstarter

I may be a little obsessed with DIY robots. We’re gradually building up a robot menagerie in the Think Physics office, and I’m planning a comparative review of some of the available kits and plans. But that’s not ready yet, and in the meantime you may like to know about this:

I met Matt and Dan at BETT at the beginning of the year, where they had a tiny stand showcasing early prototypes of their Ohbot robotic head. Think Physics bought a couple – we were showcasing one of them at the Juice Festival last week, and you’ll see them around at more of our events over the coming months. I continue to be impressed by them, and the software’s particularly good. It’s Windows-only, but adopts a Scratch-like block programming system which is both straightforward and quite flexible.

Right now, the guys are back on Kickstarter with a more developed, easier-to-build and more expressive version of Ohbot. It’s turning even more into a robot puppet, and once they get over the injection moulding hurdle it should be considerably cheaper than the previous short-run laser cut prototypes.

Ohbot’s interesting because while it is a robotics and programming project, it’s also about self-expression, dialogue, emotion, and our responses to technology. I very much like the pure robotics approach of miniature robotic arm MeArm, and the accessible turtle-graphics programming focus of Mirobot, but Ohbot is a fascinating addition to the mix. For Think Physics’ purposes, I like it because it’s clearly using the same palette of components and techniques as our other robots, and it’s also doing something rather different. If the Maker movement is about any one thing, that thing has to be “technology put to creative use”, and Ohbot is an excellent invitation to think beyond Arduino coding and wiring components together, and to really explore how we want our technology to work for us.

The Ohbot2 Kickstarter closes on Sunday morning (!), and as I write this is tantalisingly close to success. If you can help it reach its target, do pledge for one of the rewards.

Update: Success!
The Ohbot2 Kickstarter was successful on Sunday, so the team are gearing up for full-pelt production in time for Christmas. Congratulations, guys!
