Using Word Diagrams for Deep Thinking and Detailed Memories

 

In excited support of the release of the fabulous new book ‘Organise Ideas’ from Oliver Caviglioli and David Goodwin, I am sharing some of the various ways I have used word diagrams in my own practice. I hope these posts will be of particular use to teachers of economics and business, but also more widely!

----------------------------------------------------

"Whatever students think about is what they will remember"

Daniel Willingham, 'Why don't students like school?' (2021).


I am keen to have students think deeply about the content they are learning. 

Phase One: Table - Sequenced Instruction

I teach students about the characteristics of market structures using a table initially. This enables me to go cell by cell, carefully sequencing my explanation of the 6 characteristics (using an acronym, PIGPEN, to support later retrieval) in the context of each of the 4 structures. (I actually omit details on the profit row initially, but that's a sequencing story for another day!).

 


Phase Two: Tables - Retrieval Practice (& Further Instruction)

In subsequent lessons I repeatedly display a blank version of the table (or parts of it) for students to complete as a retrieval practice activity. These retrieval opportunities are faded, so support is gradually reduced. 

 

I also teach further lessons exploring each of the structures and characteristics in more detail. 

Phase Three: Diagram - Challenge

With this foundation of knowledge and developing understanding, secured in students’ memories through retrieval, I then use the diagram below to challenge them. The purpose is to have students think deeply about each of the 4 structures, about how they have some shared characteristics, about how they have some unique characteristics and about how some characteristics link to other characteristics.     



Initially I present an empty version of the diagram (as shown above) with only the market structure names in the circles and nothing in the squares. Students are provided with some bullet point reminders of broadly what to include in the squares. 

Students then need to think through the structures and characteristics in order to figure out the correct positioning of all characteristics. They are required to retrieve their existing knowledge and understanding. They are also likely to create more detailed memories of each structure and characteristic as they are required to pay more attention to them than in the earlier and more simplistic table retrieval task. (If you teach economics, you might like to try this challenge now!!). 

Following individual thinking time, pair/group discussion would take place about the correct positioning of the characteristics. 

Phase Four: Diagram - Reveal

I would then show my 'answers' (as below). 



We would discuss the diagram and I would also question students on why I have grouped some characteristics in the same squares in order to provide an opportunity for development of analytical skills and retrieval of some of the more complex content covered in the various lessons on these topics.     

Design Rationale 

I choose a complex double spray type diagram for this challenge as I want students to compare the structures and appreciate the similarities and differences between them. Applying the container metaphor, this choice is appropriate as the focus here is on the characteristics held by each structure (content), rather than any process relating to them. 

The double spray is ideal as it enables an efficient display of shared characteristics as no repetition is required in the diagram. 

It also enables students to clearly appreciate the interesting nature of the monopolistic competition structure which shares some characteristics with perfect competition, but also shares some with the polar opposite to perfect competition, monopoly. This helps students overcome potential confusion and avoid misunderstandings that can occur between very different structures with unhelpfully similar names! 


Maybe you will also now like to use it? I would love to hear your thoughts/feedback/experiences!

Many thanks to Oliver and David for their inspiration which led me to create this diagram.

Back to the Future

Ensuring something happens in the future is potentially rather easier to achieve if you possess a time machine. In theory such a contraption facilitates your travel back in time to amend things that are wrong with the present before they happen, or enables you to leap forwards to tweak moments in the future for the better. However, as Marty and Doc humorously demonstrate, this isn’t always as simple as it might seem! For the rest of us non-time-machine-owning folk, our main hope for ensuring things happen in the future lies in the effectiveness of our ‘prospective memory’. As opposed to ‘retrospective memory’ (where we are trying to remember something from the past), the concept of prospective memory refers to our ability to remember something in the future. Will you remember to wish Lucy a happy birthday tomorrow morning? Will you remember to send Jack to the office at 12.20pm for their appointment? Will you put out the garden waste bin instead of the food waste bin next week? T...

Subject Symmetry

Some subjects appear to be awash with books on how to teach them and writing on what constitutes a ‘good’ curriculum in terms of that subject. Wise subject leaders who are engaged in curriculum design would of course do well to read such material to help aid their thinking, as would senior leaders who are responsible for quality assurance.   But what if little or nothing appears to have been written about the teaching of or curriculum thinking in relation to a particular subject? Where does a subject leader go for inspiration? How do they know if their curriculum is any ‘good’ or how it could be improved? How might senior leaders attempt to quality assure that curriculum?  The answer is that the curriculum thinking must be done from scratch. Before any work can be started the parties involved need first to educate themselves in the underlying principles and concepts of curriculum theory. These generic principles then need to be tentatively applied to the subject. There is n...

Turn over a new leaf...

“What is interleaving?”  Answering this question is rather like answering the question, “what is healthy eating?” It’s complicated. Eat Your Greens Answering that eating vegetables is likely to be healthy would be correct in the eyes of most. Propelling the cabbage soup diet? Probably not. The core and important ‘vegetables are healthy’ message can become warped when taken to an extreme. The best answers to the question involve balance and sense, but there is no single answer and interpretations vary. And so it is when understanding interleaving. The core ‘mixing up topics is useful’ message of interleaving can unfortunately become seriously contorted beyond recognition and bereft of value when applied without careful thought. Only precise understanding and delicate application appear to deliver the benefits of this interesting, research-based and valuable strategy and thus these are what I encourage you to pursue. So, let me take you on a journey. Let’s explore ...
