Cognitive Load Theory: 10 Things You Need to Know.
In 2017 Dylan Wiliam tweeted to the education world that he had ‘come to the conclusion Sweller’s Cognitive Load Theory (CLT) is the single most important thing for teachers to know’. Back came a tweet, ‘shouldn’t they know their students?’. I’m not sure if that was a wisecrack or a serious challenge to CLT. Either way, it shows how easy it is to misunderstand the offering that CLT provides to teachers. The great thing about CLT is that it is a lens through which to view learning before teaching. CLT provides the door into a new age of teaching that allows us to leave behind any teaching strategies that weren’t in alignment with the research into how the human brain learns. For too long teachers have been blind to the architecture of the human brain…the only place where learning actually happens! According to CLT, when it comes to providing a productive and yet manageable cognitive challenge to students, then we need to know students’ brains. Indeed, it is CLT that invites us to really know our students. CLT invites us all to consider the brain first, learning second and teaching third. Further to this, the CLT door isn’t just the end of the ‘teaching-blind journey’, it’s also the beginning of a new journey. If you’re just stepping through this door and you wish to know what CLT is, then you might find it useful to read what I consider to be the 10 things you need to know about CLT. I ’ve written a short ‘start-up’ booklet that unpacks these 10 things. It can be found here. My aim is that on reading this document you will quickly grasp the key principles of CLT. There is more to be said for each aspect of CLT, and there is a wealth of research to read, so, enjoy! It’s a wonderful journey and, by traveling with intellectual humility, we can all travel it together!
The 10 things you need to know are:
The working memory of the brain is very limited.
Use explicit instruction for new content.
New knowledge needs to then be stored in the long term memory, ready for retrieval and transfer.
Learning happens through schema extension and connection.
Break the curriculum down into very small chronological parts.
Know the learners’ background knowledge.
Focus the attention of learners on the new content…only!
Teaching becomes redefined as ‘focussing, guiding and responding’
Identify the key schemas operating across the bigger learning journey.
Systemise CLT across the school to maintain CLT principles and reduce workload.

The implications of Cognitive Load Theory for teachers are becoming well established. However, the end result for busy teachers can end up looking like a list of ‘tips for teachers’ (‘remember not to have unnecessary animations in your powerpoint slides’, ‘remember to wait in silence while learners are processing new information before talking again’ etc.). This would be a serious watering down of the extensive research that has gone into CLT and the profound implications for teachers that has come out of that research. So, can CLT actually transform teaching in the way that it promises, and, if so, how?
In my previous post I noted that exploring adaptive teaching can lead schools into advancements with their curriculum design, quality of teaching, and, crucially, the joining of the two. Here, I present 2 basic features of curriculum design that spring out of adaptive teaching, and then 3 broad modes for approaching adapting teaching, and finally 3 classic implementation errors.
Curriculum Design: 2 Basic Features
There are two basic requirements of a curriculum designed for adaptive teaching (i.e. one that empowers the teacher to be constantly responding to learners in a purposeful way).
Using Cognitive Load Theory to Crack Addition (Part 3/3)
This blog follows on immediately from; Using Cognitive Load Theory to Crack Addition! Part 1 & Part 2.
We are picking up on children learning to add two 2-digit numbers together for the very first time in their life, and in the previous blog (Part 2) we looked at using Cognitive Load Theory to ensure that the child’s Working Memory (WM) is prepared for this moment. Here is a step by step guide to what this episode of explicit teaching looks like:
Using Cognitive Load theory to Crack Addition (Part 2/3)
There is a day in a child’s life when they first learn to solve ‘2-digit add 2-digit’ addition questions. Every child has this day! The child’s teacher wakes with great excitement. This is what it’s all about. Within this day there is an actual moment when the teacher starts their explicit instruction. This will be a beautiful moment since the child’s life is about to change…well, mathematically anyway! There are a lot of steps to teach in a child’s mathematical learning journey. They don’t all have equal weighting; some are more important than others and some are just crucial. This one is one of those crucial ones; tying shoelaces, riding a bike and ‘2-digit add 2-digit’.
Cognitive Load Theory is a ginormous beast of a pedagogical concept. At times it’s mightily complex and far from being visible in a moment, yet at other times it couldn’t be more simple, more clear and more beautiful. It is CLT that gets us to this beautiful moment!
Do you do it yourself or do you just like to watch? Blogging, I’m talking about. For a long time I’ve been on the outside, looking in…at bloggers. Some people take to it naturally (millennials probably). Not me though. I’m a reluctant blogger. My wife has been trying to persuade me to blog. Curtis (boss at Andrell Education) has been telling me to blog. My subconscious has been shouting at me to blog! But, my ‘conscious’ has been telling me to keep watching.
