What is effective teaching? The willing definition via Grant Campbell

(This post is part of a series about the New Academics Program (NAP), I’ll be using this blog to scribble notes about the NAP as I work my way through it.)

Ask ten different people what effective teaching is and you’ll get ten different answers. Here’s a handy definition (let’s call it the willing definition for now) from Grant Campbell, currently Professor of Chemical Engineering at the University of Huddersfield. The original source may possibly be from elsewhere. [1]

 “Effective teaching is inclining people to learn willingly what they would otherwise be disinclined to learn.”

So according to this definition, good teachers make you learn things you wouldn’t normally be interested in, or as campbell puts it Teaching easy interesting stuff is easy. Teaching difficult dull stuff is more of a challenge.

Is this definition useful?

This is an unusual definition, but is teaching easy interesting stuff always easy to do? Probably not. It’s also not always obvious to teachers (or students) how hard or easy things are going to be to learn. Appearances can be deceptive.

Imagine trying to teach somebody something they didn’t want to know or poorly understood. Like the Physicist Akram Khan @ProfAkramKhan, who has been trying to teach the novelist Will Self about Particle Physics, that’s hard (especially with a deliberately difficult student like Self) but the results are entertaining. Most students in higher education are considerably more willing than Self, and more motivated to work their way through the inevitable dull hard stuff that comes with every subject, so IMHO, effective teaching is about both the dull and the exciting.

Creating with the Raspberry Pi vs. Consuming Apple Pie at the Manchester Raspberry Jamboree


Thirteen year old Amy Mather aka @MiniGirlGeek steals the show at Manchester Raspberry Jam 2013

Last Saturday, the first ever Raspberry Jamboree rolled into town, organised by the unstoppable force of nature that is Alan O’Donohoe (aka @teknoteacher). The jamboree looked at the educational value of the Raspberry Pi (a $25 computer) one year on from its launch on the the 29th February 2012. Here are some brief and incomplete notes on some of the things that happened in the main room, aka ‘Jamboree Central’. The workshops and other events have been covered by Jason Barnett @boeeerb.

A key feature of the Raspberry Pi foundation (and the Jamboree) was neatly summed up by Paul Beech (aka @guru) who compared the Raspberry Pi to various Apple iThings. Paul’s view is that when it comes to computing, Apple gives you a “sandy beach, sunbed and cocktail” to passively consume digital content with while the Raspberry Pi gives you a “desert, knife and a bottle” to actively create new things (see his tweet below).

Engineering evangelist Rob Bishop used Apple Inc. to illustrate what the Raspberry Pi is about in his talk ‘one year on‘. Rob pointed out that a huge amount of effort at Apple Inc. is put into making Computing invisible and seamless. This is great if you’re consuming content on your iPad or iPhone, and what many users want – easy to use, with all the nasty internal gubbins tucked away, out of sight. This is tasty Californian Apple Pie, which many of consume in large amounts.

However, invisible computing is a problem for education, because it is difficult to demonstrate the Wonders of Computer Science (Brian Cox’s next TV series) with a device like the iPad.  Many of the internals of modern devices are completely inaccessible, and it’s non-trivial for budding young engineers to build anything very interesting with it particularly quickly.

In contrast, the Raspberry Pi can be challenging to setup, just getting the Operating System up and running isn’t always straightforward. However, there’s a ton of interesting stuff you can build with it: Nifty robotics, bionic bird boxes, musical hackery, twittering chickens, live train departure boards, internet radiossinging jelly babies and loads of other pideas. Try doing that with your iPad…

Most of the jamboree focussed not on Apple but on the things that can be created with Raspberry Pi: the What and Why and When And How and Where and Who with keynotes from Steve Furber [1] and talks and panel sessions from:

A highlight of the jamboree was the closing keynote given by the thirteen year old Mini Girl Geek on what she’s been doing with her Raspberry Pi. MiniGirlGeek (aka Amy Mather pictured above) stole the show with her demo implementations of Conway’s Game of Life in Python. [update: see video below]

What’s interesting is that Conway’s Game of Life is used as an exercise for first year undergraduates in Computer Science at the University of Cambridge. So it’s great to see teenagers mastering the “knife” of Raspberry Pi, and reminds us that Raspberry Pi is no “sunbed and cocktail” but with a little patience, ambition and talent there’s plenty to capture the imagination of young people about Computing.
