The application of Cognitive Load Theory (CLT) to teaching and learning premises on quite a straightforward idea: there’s an intrinsic difficulty to learning tasks, often made harder by extraneous load, whether that’s a cluttered slide deck with no dual coding or insufficient worked examples. Clean up the learning event and you can enable all pupils to access the intrinsic learning more efficiently. As the heading of standard 2 says in the Core Content Framework (CCF) for all new teachers, “How [all] Pupils Learn”. Only, it seems, that’s not how all pupils learn. Because learning something new actually takes effort to pay attention. And effort, it seems, is not the singular thing that many seem to think it is.

A new (2024) paper out has targeted this limited understanding of ‘effort’. It is open access and you can read it for yourself here. But it has implications for teachers and how we think about learning so it is important for us to look at their key findings.

The authors divide effort into three key areas.

Effort required by the complexity of the task.

The harder it is, the more effort. We know a lot about this. Not enough difficulty and we become apathetic and demotivated. Too much difficulty and we get disillusioned. This is the area CLT is focused on. Let’s enable pupils to tackle more difficult tasks by reducing the extraneous load and improving their ability to tackle things through worked examples and well designed dual coding.

Effort required to focus (including how much you are averse to focusing on it!)

The continuous focus a task demands is not related to its difficulty. You could be having to complete a large spreadsheet using very similar tasks over and over. Copy and pasting and calculating. It requires focus, but it’s not hard. In fact it’s quite boring. Boring, it seems, requires more effort. It’s painful to have to focus when something is boring. I think we can all think of examples of this one!

Motivational effort

Generally, students are ready to allocate effort if they are motivated. These can be extrinsically motivated via deferred gratification (e.g. qualifications and monetary rewards) and intrinsically motivated such as through epistemic curiosity or prior positive experiences. However, students can also not be motivated by deferred gratification. ImPact’s latest report on pupil absence suggests persistently absent pupils are less motivated by deferred gratification and that a sense of belonging could be more powerful in providing motivation.

To put this into teacher terms and get an understanding of how all 3 types affect a single task with a consistent intrinsic load, let us think about the act of marking and assessment.

To assess a work against criteria, you have to conceptually hold the entire work in your head. This can be quite difficult for longer extended writing pieces with large amounts of information. You also have to have the subject knowledge to assess it whether for subject content or for spelling and grammar. There is an innate and intrinsic difficulty to assessment (sometimes made unnecessarily harder by illegible handwriting and no quiet working space to concentrate on the marking!)

To mark work, you have to focus. That’s actually quite hard for many who have to assess. To mark for one hour takes focus and concentration. It’s tiring and sometimes you are too tired to mark. Sometimes you have to mark huge amounts like during mock examinations or when you are working as an examiner and you are grinding through endless similar answers over and over.

And that leads us to motivation. Remember the days of triple marking and multiple colour pens? Of ‘Verbal Feedback Given’ stamps? Or even today’s double and triple mock examinations where schools are trying to wring extra points out of pupils via exam practice. You might not always be that motivated to mark these. You might feel this should be outsourced (as some schools do) and that a third set of mocks is not spending your time well. You may well really dislike marking, which may be viewed as a tax on your ‘free’ time. Many polls of teachers find this one of the least liked areas of teaching. It’s no secret exam boards struggle to recruit examiners.

And so it’s not enough just to think about the difficulty of marking. You have to think about the need to focus during the act of marking and the motivation needed to do your marking. It’s why we do things like whole class feedback instead of marking whole sets of books. Marking whole sets of books with detailed annotation can require lots of effort even though it is not actually hard to do.

Now reflect on effort in your lessons – the same principles around effort applies to students. We need to think not just about the first area of effort which CLT attempts to optimise, but also the other two areas of focus and motivation. A group of trust leaders told Jon Severs of the TES that a more diverse curriculum with less content to cover (to summarise his meeting with them) might mean students can focus on English and maths more effectively because they have other subjects which they really, and I mean really, enjoy, but more importantly also make them feel part of the school and motivated to enjoy school. We have to see school not just made up of tiny episodes of teaching and learning which all pupils experience in the same way, but as a ‘whole’ school experience for a diverse range of learners who need to be able to generate the three types of effort needed to enjoy and succeed during their time in school.
