The Green Light

In 1976, when I was a school student in Grade 8, we had a wonderful science teacher who had a part-time job at night running the mainframes at Macquarie University. He managed to obtain an old Fortran punchcard machine that he brought to school and taught us to program with, and every day he would take our punched cards to the university with him and run our simulations late at night (Remember how much money computer time used to cost back then?)

As a science project, our whole class walked up the nearest busy traffic light near the school and we counted cars as they went through all the various possible turn options at the intersection. We took all this raw data back to school, punched it onto the Fortran cards to adjust the timing of the lights to make them more efficient. Each day our teacher would come back to class with reams and reams of dot-matrix computer printouts showing graphs of the traffic flow numbers. We would get our groups’ printout, analyse it, work out ways to improve it, and then go back to the punchcard machine to revise our timings and create a new batch of cards. This process was repeated lots of times until we had a perfectly adjusted timing light sequence.

Was this part of the standard science curriculum for Grade 8 in 1976? I doubt it. But as you can see, I remember it like it was yesterday and it was one of the best experiences of my school days. It was “hard fun”, it was an authentic, real-world task. And with the level of thinking and programming and learning involved, it was probably way above the normal expectations of Grade 8 students.

Maybe that’s why I liked it so much…

Making Powerful Points

PowerPoint cops a lot of flak sometimes. People often use it in a way that is overdone, hackneyed, clichéd, uncreative and just plain boring. You’ll often hear the phrase “death by PowerPoint”, as presenters try to wear you down with slide after boring slide of bulleted points and flying text effects. Although PowerPoint is still seen by some teachers as a useful tool for education, it’s relevance in a Web 2.0 world seems to be on the decline and I’ve heard a number of disparaging comments about poor old PowerPoint recently suggesting that it’s time in the educational sun is well and truly over.

I can understand why any teacher who has been teaching with with technology for a while might be sick of PowerPoint. They’ve no doubt sat through dozens, even hundreds, of PowerPoint presentations over the years. Many of these have been peppered with flying text that swoops across the page letter by letter while making swooshing sounds, or seeing slides that require 30 clicks to build a series of stretched, distorted and probably irrelevant images that drop, bounce, swish and zoom their way onto the slide. And despite the fact that students may have learnt to use every animation, transition and graphic effect available in the software, the amount of “learning” in the traditional content-based sense is often very minimal.

And yet for teachers who are only just now starting to introduce PowerPoint into their classroom, or who have never gotten their students to present using PowerPoint at all (and surprisingly, there are still quite a few of these teachers) there remains a certain funky factor about PowerPoint that makes it easy for the whizz-bangery of the effects to overshadow the fact that very little actual communicating or learning is taking place.

But there’s no denying that the ability to present – to be able to stand in front of an audience and explain, persuade and influence them to your point of view – is an extremely valuable skill. And whether you like them or not, the use of persuasive visual tools like PowerPoint or Keynote is a highly valued ability in many organisations. If you can stand up in front of people and give a decent presentation it will take you a long way.

The problem of course is that when most kids do presentations they are big on the PowerPoint part, but not too good on the speaking part. In too many cases they stand there with their backs to the audience and just read the text on their slides, while the animation effects are completely over the top. They too-often mumble their way through the slides and put the audience to sleep. They produce boring presentations… and it’s a shame, because PowerPoint/Keynote is actually an amazingly powerful tool if you use it right. It’s just that most kids don’t get taught to use it right.

I particularly like the work of Cliff Atkinson and his Beyond Bullet Points approach. I tried a modified version of it with some kids earlier this year with stunningly effective results. The idea is simple… less is more… get the text off the slides. If there is no text (or at least minimal text) on the slides then kids can’t just read the slides to the audience. It’s a simple approach but it works really well. Atkinson actually has a whole methodology to what he does, starting with a outlined list in Word and then importing that into PowerPoint. This puts the main idea points as a heading at the top of each slide. You add the bullet pointy stuff that you would have normally added to the slide into the notes section instead (so the audience never sees it, but it gives the presenter a written list of what they plan to cover.) Then you find an image or photograph that expresses the idea you’re trying to get across, add it to the slide, and that’s basically it. I also don’t allow the kids to have cue cards… so no notes, no fumbling, no reading.

When the kids present their slideshow they cannot read the slides to us, as there is really nothing up on the screen to read. They don’t have cue cards in their hands so they don’t look down all the time and mumble. The imagery engages the audience surprisingly more than the text ever would, and the presenter has to talk to the audience because they find themselves needing to actually explain the point they are making. The presentation becomes much more conversational, and not just a rote speech with distracting animations. I was amazed at how well this works.

I have since been experimenting with this “no text” idea. I’ve done it several times now, with several groups, in several ways and I have been consistently seeing the best PowerPoint presentations I’ve seen in 15 years of teaching with technology. I am absolutely amazed at the results.

For example, I asked a grade 9/10 class last week to find a current Internet news article (within 14 days) on some aspect of technology that interests them, and then to come up with a short summary of the article and five questions that the article raises. They then turned this into an 8 slide PowerPoint file (title, article summary, five question slides, and a citation slide at the end). They had to do a quick 3-4 minute presentation to the class on their article. They could not use notes or cue cards. They had to present their answers to the five questions, but of course their answers were not written on the slides so they had to know what they were talking about. This group did some of the best presentations I’ve ever seen. They were confident, they spoke well, made eye contact, interacted with the group and covered their chosen topics with surprising clarity and depth of understanding. I think they surprised themselves too, and many gave a confident, polished presentation that went for more than the minimum 3-4 minutes..

Then I did something similar with a grade 11 class, only even more simplified… pick a topic that interests you and present it to the class. No notes. No text on your slides. Again, they were some of the best presentations I’ve seen in ages, and myself and the rest of the class were totally engaged with the presenters as they came up one by one to tell their stories. Surprisingly, before they gave their talks most of them insisted they were not at all keen to speak in front of their peers. But after it was done, most said that not only was not as scary as they thought it would be, but many actually quite enjoyed it.

Of course, through all of this I was hammering these kids about the idea that YOU are the magic, not the slideshow. I kept telling them that the slideshow was secondary, and they it was them that the audience was engaging with. I think that combined with my nagging about it, and these techniques of less text/no notes/lots of images, they actually learnt quite a lot about presenting with visual tools. I also spent a lot of time developing their skills in building animations and thinking about the ways that animation can be used to visually convey an idea in stages. Oh, and getting the text off the slides.

I think that PowerPoint deserves a lot of the criticism gets, because too many teachers/kids/presenters use it primarily as eye candy and visual effects instead of a powerful tool for assisting a presenter persuade and inform their audience. If you’re feeling jaded by PowerPoint, give this approach a go. Keep it simple and take the focus off the slides. I’m convinced it makes a massive difference to the way PowerPoint gets used, and once you get the idea that it’s not really about conveying subject content, but more about learning communication skills in front of an audience, then I think humble old PowerPoint can have some really positive learning benefits.  Give it a try and let me know how it works for you…

Data Projectors for Dummies

Back in the day, when data projectors were still somewhat of a novelty, it was probably acceptable to be a little unsure of how to set one up.  But these days we are finding them in great demand and although our school techs are still willing to come set it up for teachers if they ask, I think there ought to come a point when we learn to do these things for ourselves.  I mean, you don’t ask a tech to come set up an regular overheap projector for you, or a TV and DVD player, so why would a data projector be any different?  As our classrooms start to depend more and more on a range of “devices”, surely we need to know how to use them for ourselves?

Anyway, In an attempt to ease the way (and more-or-less gently drop the hint that it’s about time some of you figured out how to do this stuff for yourselves) I made this little video that explains the step-by-step process of using a data projector the right way. 

After adding it to our intranet, I had a copy just sitting on my hard drive so I figured I may as well share it with the rest of the world on my blog (Not that the rest of the world reads my blog mind you!)  It might be of some use to someone.

Your comments are welcome.  And yes, I know I needed a haircut.
