Two weeks ago, I blogged about the virtues of teaching simple lessons with a repetitive structure. One of the comments left beneath the piece was in agreement, but implored me to go further:
…abandon powerpoints all together. I have been freer since I embraced the idea that very little can be taught well using an image that cannot be better taught using words.
This is something I hear a lot, often from traditionalist teachers with whom I share common ground on many other issues. I listen to their arguments, I agree with much of what they say, but I simply cannot give up my attachment to PowerPoint. I use PowerPoint presentations in nearly all of my history lessons. Sometimes, I consider giving it up for a fortnight, just to see how it feels, but cannot even bring myself to do that.
I am well aware of the multiple crimes which can be laid at PowerPoint’s door, and fully accept that it often makes teaching much worse. Three of PowerPoint’s most serious crimes against teaching, from my experience, are:
- PowerPoint = the lesson: Have you ever noticed how ‘the PowerPoint presentation’ is often used as a synonym for ‘the lesson’? As in, ‘I have just put the lesson is on the shared drive’. Such a mindset has dire consequences. It tempts teachers to use PowerPoint as a crutch, and assume that they no longer need to give prior thought to their lesson sequencing, explanations, and questioning, because ‘it is all there on the PowerPoint’. One of the worst teaching habits that PowerPoint presentations encourage is allowing slides to become the replacement for a textbook. It is only a small step from that, to the cardinal sin of teaching-as-reading-off-the-PowerPoint (common amongst much CPD, incidentally).
- Engaging PowerPoints: Giffs, cartoon characters, pop culture references, clip art, comic sans, lurid colours, cluttered slides. Can’t bear it, hate it all. If you are engaging pupils with material unrelated to lesson content, their engagement is worthless.
- Time thievery: My biggest disappointment following my first ever day of teaching was that no pupil stayed behind to thank me for designing such a lovely PowerPoint presentation. I had spent hours on the bloody thing. It had animations, transitions, a colour scheme, little jokes, and not one pupil batted an eyelid. Of course, creating those types of PowerPoint presentation is a colossal waste of time.
All that being said, I do think that PowerPoint’s advantages can compensate for its deficiencies. The three most significant for my practice are as follows:
- Imagery: There is clear evidence from the field of cognitive psychology that combining images and words aids memory – a process known as ‘dual coding’. I sense this phenomenon at work all the time in my history lessons. Pupils at Key Stage 3 find it much easier to remember characters from the Tudor period, for whom we have wonderful portraits (Henry VIII, Anne Boleyn, Mary I, Thomas Wolsey and so on) than those from the medieval period, for whom we don’t (Thomas Becket, Henry II, Edward I, Edward III). Well-chosen historical images can illustrate a period in ways that words simply cannot. And they minimise the misconceptions that may occur if you tried to explain the appearance of, for example, an ornate Catholic alter or a Victorian back-to-back house, verbally. Just this week, I have used scenes from Lutrell’s Psalter and Très Riches Heures du Duc de Berry to illustrate life in a medieval village to Year 7; Foxe’s Book of Martyrs to illustrate the reign of Mary I to Year 8; and a fantastic animated diagram of James Watt’s steam engine from the Museum of Scotland to illustrate the Industrial Revolution to Year 9. I would hate for my lessons not to have this visual aspect.
- Instructions and information: Though I try to keep text to a minimum, my PowerPoint presentations do contain some instructions and information. This may be keyword definitions, for pupils to copy into their books, or a mnemonic to remember how to analyse a historical source. Every other lesson I teach starts with a recap quiz, for which the questions are projected on the board. Of course, I could print all of this information, but I would weep for the trees. Or I could place it all in pre-prepared booklets, but I don’t think I would ever be sufficiently happy with a unit not to want to adapt it midway through teaching according to unforeseen issues and misconceptions.
- More teaching time: Whilst I do teach with my board pen in hand, I don’t like to spend time writing large chunks of text on the board. This is perhaps rooted in having begun my career in a school where turning your back on the class for one moment normally meant turning back to a scene resembling a medieval doom painting. But even in a school where behaviour is not a concern, I still like to maximise the time I spend facing the class, monitoring how well they are working. PowerPoint allows for this.
In sum, I think that PowerPoint can be tolerated, so long as it is seen as an aid for the lesson, and not the lesson itself. If a PowerPoint presentation never takes more than 15 minutes to prepare, consists mostly of well-chosen images that complement and do not distract from lesson content, and includes instructions and information but no large chunks of writing, then I think it is no bad thing.
