Some teams go to very similar sessions. This aids conversations. We also write up one session for T&L newsletter. It’s also all the conversations while we travel by train and plane help too. Many of our staff all sit on T&L team so helps to inform. Lots of ways! Some formal some informal.

These were created using latex code and in the end I just edited the latex labels rather than redrawing each one. I got a little lazy, but appreciate the detailed eye!

This week I’ve written about how we can apply the approach we took with metric unit conversions for area and volume onto area and volume of similar shapes. open.substack.com/pub/fantasti...

Ratio tables and Similar Shapes
Now we’ve created a unified model of unit conversions from linear to volume conversions using the ratio table as our scaffold.

This weeks post is a two for one. I question when scaffolding isn’t actually having the desired impact. I give an example of a commonly used scaffold for unit conversions which I now think doesn’t actually support our students in the long run. substack.com/@fantasticma...

Grouping/setting students to enable mastery as that would be one of the conditions for mastery akin to Blooms proposal for mastery. Opposed to the problematic definitions of which now exist according to EEF.

Deep learning doesn’t have to be stumbled upon through inquiry it can be specifically taught and connected. The opportunity cost of inquiry learning is too high to promote in this manner.

Jon Fant @fantasticmaths.bsky.social · 09/11/2025
If you’re still using Hattie places direct instruction approach at 0.6. Mastery learning and explicit teaching statergies at 0.57. I suspect you’re encouraging explicit teaching rather than DI programs. Where as inquiry and cooperative learning are at 0.4.

Non germane cognitive load eg what font do I need to use. The new version of bubble writing. Even who is going to do what. Oh that persons job is to watch the others do the work and therefore the learning? Enquiry learning, hard pass, On the research front. EEF haven’t ranked it.

Jon Fant @fantasticmaths.bsky.social · 09/11/2025
Remembering that a DI style approach is highly interactive. Ensures that all students come along the journey. Ensures that everyone is thinking hard. Ensures that attention is in the right place for learning to happen. Enquiry does none of this, it introduces cognitive load in a variety of ways

Jon Fant @fantasticmaths.bsky.social · 09/11/2025
Disagree for children in schools. They would move into the gradual release phase of direct instruction. Really true enquiry is going to be when beyond novice, beyond simple automaticity. Stick with direct instruction approach but move into the gradual release phase. Stick with what works.

Are you planning to introduce some degree of direct/ explicit instruction with example problem pairs and fluency practise. Are you going to go down a conceptual/visible approach like @mrmattock.bsky.social or more of a Kris Boulton style of approach.

Jon Fant @fantasticmaths.bsky.social · 17/10/2025
Once you’ve decided what you think the research says mastery is or isn’t. Then you need to consider the pedagogical approach that will take you towards that journey. These pedagogical approaches can probably be introduced in the interim as they will have their own gains.

Jon Fant @fantasticmaths.bsky.social · 17/10/2025
First you need to try and decipher what you think mastery is. There is an EEF guidance document. educationendowmentfoundation.org.uk/education-ev... Confusingly I think @markmccourt.bsky.social book would be more likely to describe mastery learning that teaching for mastery on the EEF definitions.

Mastery learning
In mastery learning, learning outcomes are kept constant but the time needed for pupils to become proficient is varied.
