The ultimate teaching technique

//The ultimate teaching technique

UPDATE: I no longer agree with any of the following. It remains on my blog as a warning against hubris. June, 2016

Maybe it’s just me, but I seem to be encountering an awful lot of people railing against ‘progressive’ teaching methods of late (see this for an example.) There seems to some sort of consensus that all schools are bastions of constructivist theory in action and that seldom, if ever, are teachers allowed to waffle from the front. Sadly, my experience is that many teachers still spend far too much time standing at the front of their classes talking at students. Why does this happen despite the widely held wisdom that 80% of the time in lessons should be spent with students getting on with independent work? Well, my view is that it’s a damn sight easier to just pitch up and drone on. It requires a good deal more preparation to get a class working independently like a well-oiled learning machine.

This is not to say that there is not a time and a place for ‘teacher talk’: there absolutely is. Whenever we want students to learn large amounts of information the most effective and efficient tactic can be the ‘traditional’ approach of direction instruction. For those wanting to find out more, I’ve written about it here.

But, you may be relieved to hear, this isn’t the only  approach to the imparting of knowledge. My absolute favourite way to teach is using Home and Expert groups. If you have a large quantity of wonderful new information that students need to learn and don’t fancy subjecting them to death by Power Point or perpetrating some other passive, teach lead thought crime, the Home/Expert method may be for you. The material you wish students to learn must be divided in into five discrete ‘bits’ with students required to become ‘experts’ on one of these five areas. Each member of the expert group is then responsible for taking back whatever it is they’ve learned to their home group who then have to synthesise the entirety of the material in a manner of your (or their) choosing. Everyone is required to work at all times, otherwise the home groups will be unable to complete their challenge and the miscreant responsible for this failure can be publicly lambasted.

Kids learn enormous amounts from this activity: it develops skills of oracy and of turn taking; they also learn predominantly from each other. Your are not involved in any way other than as a facilitator, and as such, it is a serious, über-constructivist, Ofsted pleaser.

Phil Beadle[i]

Although he calls it ‘jigsawing’, Phil Beadle says this is the ultimate of all teaching techniques”. I’ve also heard it called ‘snowballing’ and it probably goes by other monikers as well, but I’ve always called it Home and Expert Groups and when it works it is a thing of beauty, wonderful to behold.

The main thing is to ensure the groupings and movement work with military precision. I’ve worked with teachers who approach this very successfully on an impromptu basis, but if you’re trying it for the first time I’d recommend some serious advance planning. One way to approach this is to give each student several different groups to which they belong and corresponding seating plans.

This might mean that in class of 30 students you would have five groups of six students. Let’s make these colour groups:

These are our ‘home’ groups. Home groups are all given the same task e.g. summarise Act 2 of Romeo and Juliet or produce a guide to cell division or whatever it is you want. Clearly, this is too big a task to complete in the hour available so we need to move students into expert groups. Let’s make these shape groups:

download (1)

These groupings have several potential uses. Firstly, if students know in advance that they are, say a green pentagon then they’ll know exactly where to move when you say, right – move to your expert groups. Also,  you can work out groupings based on ability, team skills, personality types, gender and so on. The possibilities are only limited by your ability to think up different ways to organise them.

In order to minimise the amount of movement, you might want to inform students that they need to sit in their expert (shape) groups as they enter the room. Then, once you consider they’ve had sufficient time to digest the source material you can blow a whistle or signal time in some other, less piecing way and have every swap to their home (colour) groups to share their findings and work on whatever task it is you’ve set them. My advice here is to give students less time than you think they’ll need. Experience suggests that the time required to complete group activities increases in direct proportion to the amount of time they given.

The most important information students need to know is that their expert group is the only group dealing with the vitally important information which they are privy to and that if they are not all working hard to make sense of it, they’ll be empty handed and exposed as a work-shy oik when reporting back to their home group.

The very best thing about this way of teaching is that it all happens without your direct involvement. You’re left free to roam the room giving feedback as and when appropriate, engaging in high quality conversations about the learning which is quite patently unfolding before your happy eyes. Result.

If you doubt that this is a better way to approach the dissemination of knowledge, try it. Compare how much students subsequently know after teaching this way and after engaging in some direct instruction. You may just find yourself surprised.

    Great post. I’ve used this in the past, really like it. I think that the key to it is coming up with a really effective exercise that demands the students have to meaningfully synthesise the information they’ve gathered in their expert groups. Although obviously getting students to move around the room without wreaking havoc is also important!

    Great post. I use this technique a lot in History as it gets through a great deal of information quickly, effectively and at a good pace. A variation on the theme is something I have heard called “World Cafe” – each group has different information and records it on a tablecloth over their table. As students move around the tables they add relevant info – really good for showing links between aspects of topics

      Thanks Penny & John. Good to know jigsawing is as popular as ever. Like the table clothes idea. I really want to get hold of some ideapaint and turn my tables into whiteboards!

    Tried a version of this today with a poem, with Year 10, with students working in groups, doing close reading of one stanza of a three stanza poem. They are to reform into groups of 3 in tomorrow’s lesson to jointly build an overall interpretation of the poem. I’m feeling pretty unsure, though: perhaps this method suits ‘information’ better than analysis of literary texts? Generally I regularly do what you might call ‘expert groups followed by feedback to whole class’. I also do the latter regularly with A Level classes. Maybe it’s being a control freak, but I do worry that when they’re struggling with a difficult text, I shouldn’t leave them on their own to pass on to their peers their misunderstandings or limited understanding.

      A thorny issue. I really understand your concern about students not ‘getting’ texts. However, if they have to ZOOM IN and OUT showing an awareness of the big picture as well as the micro analysis of words/phrases then they should arrive at something which they can justify. At that’s the point, isn’t it? English teaching is all about defending our interpretations. Also, if we don’t give them the chance to get it wrong and learn from mistakes, how will they cope with unseen texts?

    I love this technique and use it a lot to teach science (ethical areas rather than factual), my only concern is wondering about the contribution less able students can make to expert groups, and whether this will impede the learning of more able. I wonder whether I should also arrange expert groups into more/less able to avoid this.

    I love this activity and use it a lot in Geography especially for case studies. I like how every pupils has to get involved and can’t afford to be a passenger in the lesson.
    See also the ‘Market Place’ activity in Paul Ginnis’ Teacher Toolkit for a variation on this general type of group work/peer teaching.

    All the literature goes into detail about group sizes but nothing says what sort of group tasks they do. Lets say its a geography case study as @geogjo suggests, what do they then do with the info? Do they “teach” the others the info the do the group task or do they go straight into a task?

    Luke, the point is that this technique allows you to get through a large quantity of information without you having to teach any of it. In the case of a geography case study, split it up into 5 bits (or even better 5 case studies) then make sure everyone in the expert groups knows they are responsible for teaching everyone in their home group. Simples.

    Yeah I get the idea but I still struggle with the ending. Do people think the end result should be everyone to have notes on the topic? If its about “knowing it” how do they show their understanding? What tasks are suitable for proving they’ve learnt a topic? I believe in and use the strategy but I struggle after the experts have taught their teams.

    A very good post indeed. Similar to David, I am a teacher who was trained with direct instruction techniques and who has on his teaching journey adapted his teaching to now work within a flexible learning space in a school that uses inquiry based learning. David has identified the contrasting pedagogical approaches that we as teachers need to objectively critique and adapt in order to promote successful and quality learning experiences within our classrooms. Robert Slavin’s book on “Cooperative Learning: Theory, Research and Practice” has good information on several cooperative learning techniques: ‘Group Investigation’; ‘Co-Op Co-Op’; and ‘Jigsaw II’. One of his underlying requirements for success in cooperative learning is accountability to a group objective. His cooperative learning techniques have been critiqued adapted by Dr Spencer Kagan in “Cooperative Learning” and Dylan Wiliam in “Embedded Formative Assessment”. Additionally, one of your fellow countrymen, Paul Ginnis, in his excellent book “The Teacher’s Toolkit”, has devised ‘Marketplace’ which has extensive and adaptable instructions for its use. It uses a good method of designing expert posters with a limited number of words on each poster to ensure communication and understanding occur and not just copying another student’s good notes. Of course you need to establish your desired learning outcome, whether it is a discussion around analysis of a topic / text or the creation of a product. No silver bullets as one size does not fit all here, but that’s what makes teaching challenging and a great vocation.

It seems that one of the main objections to group work is that it has in some way a constructivist, anti-knowledge agenda, and who knows? Maybe in some teachers’ minds it does.

    Very informative post. Just as a matter of interest, at what stage in the learning cycle do you see this technique as being most appropriate?

    • David Didau May 16, 2017 at 1:30 pm - Reply

      I no longer think this is an effective way to teach so I wouldn’t ever recommend it.

      • Jimmy May 16, 2017 at 4:43 pm - Reply

        Sorry, it always helps if you read the health warning at the top. Judging from the final paragraph I am assuming it is something you might have used as part of the explanation stage. May I ask why you are no longer an advocate this technique? Thanks

Constructive feedback is always appreciated
