Eedi Blog

At Eedi, our mission is to support teachers in identifying and addressing students’ misconceptions in mathematics. That’s why we're excited by a new research paper authored by Kasia Kobalczyk, a PhD student at the University of Cambridge. Her paper, Active Task Disambiguation with LLMs, has been selected as a Spotlight at ICLR 2025 and offers a compelling strategy for improving the quality of AI-generat ed content and human-AI alignment. The twist? It’s not about giving better answers—it’s about asking better questions.

At Eedi, we’re obsessed with a deceptively simple question: why do students get things wrong? We’re not talking about slips like picking B instead of A by accident. We’re talking about the deeper kind of wrong, like when a student always works left to right, ignoring the order of operations. These kind of mistakes reveal something something more profound: a **misconception**. If we can spot them, we can intervene and prevent a *misconception cascade*, where unresolved misconceptions lead to new ones.

Why 120 questions per year can transform maths progress in your class... At Eedi, teachers often ask: *“How many quizzes do my students really need to complete to meaningfully improve their maths?”* Thanks to a rigorous, externally conducted study, we now have a clear answer: students significantly benefit when they complete at least **120 Eedi check-in questions** over the course of a school year. Here’s what this means in practice — and why it matters for you and your students.

Independent research confirms: Eedi delivers maths improvements equivalent to approximately 3–4 months of additional learning—with just 10 minutes of weekly engagement.

At Eedi, we’re constantly pushing the boundaries of how data and AI can improve learning outcomes for students—and this time, we’re taking it to the next level. Simon Woodhead, Eedi’s Chief Data Scientist, shares an exciting behind-the-scenes look at how we’re using AI and competitions to tackle one of education’s toughest challenges: identifying and addressing student misconceptions in mathematics.

Eedi is proud to announce that our innovative math education tool, AnSearch, has been selected as one of 50 winning teams in the global 2023-24 Tools Competition. This recognition places us at the forefront of educational technology innovation, addressing pressing issues in education worldwide.

Time for another round of coaching case studies where I reflect on some of the things I have learned from working with fantastic teachers around the country.

The countdown to this year’s GCSE Maths exams is well and truly on. So, I thought it would be worthwhile sharing two ideas for effective revision lessons that I have picked up during my recent visits to schools.

I thought I would share two more case studies from the schools and teachers I have been lucky enough to work with over the last few weeks. The first case study focuses on modelling and the second focuses on checking understanding.

This week we have been working on a free resource to support your GCSE students in the build-up to their GCSE Maths exams called... the GCSE Big 20 Revision Quizzes 🎉

A few weeks ago I was working with a maths department that was trying to get their students to engage with what I call Intelligent Practice. These are sequences of questions where consecutive examples are related to each other in a certain way, and by encouraging students to think hard about these relationships we draw their attention to key concepts underlying mathematical ideas.

Last week I wrote about how I approach instructional coaching. I was lucky enough to put this process into practice when I worked with lovely colleagues from the maths department at a school in the Midlands. Here is what I worked on with two colleagues in case they resonate with your own teaching practice.

Occasionally I am asked to work with teachers one at a time as part of instructional coaching. In fact, that is exactly what I will be doing this Thursday at a school in the Midlands. In preparation for the day, I have revisited my favourite coaching resources and refined my coaching process.

Most weeks I am lucky to be able to work with schools to help support their maths teaching. I always learn far more from these visits than the colleagues I work with learn from me, and my recent visit to The Telford Park School was no exception.

With school closures interrupting learning earlier this year, maths anxiety is all the more likely in this crazy world we're all getting used to. Watch our on-demand webinar with actionable tips on helping children build mathematical resilience and reduce maths anxiety.

Let's start with our big announcement ... Eedi Family is now available for children in Year 6 & Year 8! 🥳 The new lessons will help Year 6s with their SATs and Year 8s to catch up on vital concepts they missed during their all important first year of secondary school due to lockdown.

Last time we talked in early April we'd raised £3.5M from Lego and we were about to begin our journey into product development and commercialisation. That's exactly what we've been doing 🎉 We just released Eedi Family beta, and that brings us to where we are today.

This week we turn our attention to Ratio.
