My colleague Colin Foster has released a new resource designed for secondary mathematics teachers: “Teaching the Big Ideas in School Mathematics”. Available here: bigmathematicalideas.org

Enjoyed reading this recent paper by @davidjpurpura.bsky.social and Jasmine Ernst. Really cool! :) www.sciencedirect.com/science/arti...

Can you tell which line below is longer? No? Then maybe humans cannot discriminate similar numbers with an approximate mental mechanism either. Read more about it at osf.io/6m4zw

In a number comparison task, the size effect is, in fact, at least three distinct size effects with three corresponding generators. See more details about the anatomy of the number comparison size effect at doi.org/10.3758/s134...

I like this paper by @coolenilse.bsky.social www.psycharchives.org/en/item/9754...

Very cool paper 😎

The Approximate Number System account assumes an imprecise mechanism behind the precise symbolic number comparison. This leads to various contradictions in the model. Read more about it at osf.io/6m4zw.

This THE article quotes an EEF spokesperson discussing a 2019 Educational Researcher article on RCTs I coauthored. But the EEF has misunderstood: “uninformative” does not mean “finds no difference”. https://www.timeshighereducation.com/news/time-review-sidelining-education-faculties-researcher

Different evaluation methods may categorize subset-knowers as CP-knowers and the other way around. Picture below: how various methods categorize children differently. See details in psyarxiv.com/cz9ug

I'm delighted to share this interesting work, a wonderful collaboration with colleagues based in the Canary Islands. ☀️ Acta Psychol. 2026 [https://lnkd.in/e3Q_xQ-H]. #MathAnxiety #MathEd #MathTeacher #CogSci #Edusky #DevPsy @mclstrainee.bsky.social @mcls-official.bsky.social @ioe.bsky.social

I recently started a postdoc at NTNU in Norway. Very happy 😎!

New paper on the nature of order processing deficits in developmental dyscalculia! 💙 Shared first-authorship w/ Dr. Natalia Dubinkina! Open access: doi.org/10.1016/j.je...

Hello #tRNS lovers: 🧠 Ó Dúinín, E., Steopan J., Kessler, K., Santos, FH. Sci Rep 15, 37977 (2025) 🎯 rdcu.be/eNuQT @mcls-official.bsky.social @mclstrainee.bsky.social @ioe.bsky.social @ucl-ioe-phd.bsky.social #neuroskyence #cogsci #edusky #devpsy Sponsored by @ucddublin.bsky.social Ad Astra

The SNARC effect may work only with symbolic numbers. It seems to work with nonsymbolic numbers when the task requires symbolic responses, such as "smaller"-"larger", but not without them. doi.org/10.1037/xhp0... or www.thenumberworks.org/discrete_sem...

Great to be back to Cracow after almost 10 years of academic „nomad life” :)

Delighted to share the first article of Dr Sophie Leonard's doctoral thesis. We thank reviewers & editors of this exciting special issue for their great support! ☘️ #ProudSupervisor #neuroskyence #devpsych #cogsci #edusky @mclstrainee.bsky.social @mcls-official.bsky.social @ioe.bsky.social

✨Request for unpublished data✨ Meta-analysis on early (age 3 to 6 years) math interventions. Please reach out to me (Mary DePascale) or Nicole Scalise by November 9 if you are willing to share your data!

Should you use LLMs to summarize articles or conduct systematic reviews? No! 1-LLMs can’t evaluate article quality 2-They overstate study results 3-WTH is the point of being an academic if we don’t even read each others work!!!

I’m looking for a study where someone has looked at accuracy on Raven’s matrices (or similar) items under extreme time pressure at the item level (not time pressure at the test level). I can’t find anything, but surely this study must exist?

How do early years educators engage with research? I recently spoke with some early years educators to find out 💡 Read my blogpost for a summary of my findings ⤵️ blog.lboro.ac.uk/cmc/2025/04/...

"Effective research communication in education: Early years practitioners' views of research summaries" In my newest paper, I discuss the importance of understanding how early years practitioners engage with research & what I learnt from speaking to them.💡 Free access here: doi.org/10.1002/rev3...

Really enjoyed reading this thoughtful and insightful piece on tips for school-based data collection by @natashacguy.bsky.social. It's clear, practical, and packed with great advice. A must-read for anyone planning research projects in schools!

In our new paper, we identify six key phases for success in bridging the gap between research and practice, drawing together findings from a range of disciplines: Engage 📢 Understand 💡 Value 💛 Commit 🤝 Adapt 🛠️ Sustain ♻️ Linked below ⬇️ 1/2

New from the lab: on the importance of conceptual knowledge for children's (adaptive) strategy use in arithmetic link.springer.com/article/10.1... - resonates with pleas for basic (but adaptive!) knowledge in (math) education in view of latest PISA results.

Please send me your suggestions of what to read. Self-promotion welcome! Doesn’t have to be math cog related. #PsychSciSky

My fantastic PhD @lillyroth.bsky.social got her first Reigstered Report in PCI accepted (stage 1) in a collaboration with @krzysztofcipora.bsky.social Ulf Reips and John Caffier. "One and only SNARC? A Registered Report on the SNARC Effect’s Range Dependency" rr.peercommunityin.org/articles/rec...

4th Dec. Returning to my roots with a paper on children’s understanding of inverse relation between + and - Ching replicates previous work showing some 5 yr olds use inverse principle in true quantitative sense and show quant use only related to VSWM and inhib. Suggest it could be related to SFON.

This term I have been overwhelmed by admin, management and meetings. It has sucked all the joy out of my job. In an attempt to improve things I’m doing a paper reading advent calendar. I’ll read and share one paper a day* from now until Christmas. See ⬇️ (*sometimes a skim read and not weekends!)

Spread our flyer to make the MCLS Trainee Community larger! Send it to trainees in the field of numerical cognition and math education who might not know us yet :) (Flyer in different languages: drive.google.com/drive/folder...)

My favourite* thing about doing a postdoc is getting to spend the entire postdoc applying for other postdocs *I hate it

Great workshop on using #PsychoPy to study rodent decision making today at UCL! We created a task based on this paper elifesciences.org/articles/63711 Materials are open, please download, share and reuse 😊🔓 tinyurl.com/yttzfuf8

Putting aside the introspection disputes, I am wondering how many similar phenomena we are missing out by just not asking proper questions....

Looking forward to our Loughborough Open Research Working Group meeting this morning. Rights retention next steps on the agenda. Any top tips on communication to academics? #PsychSciSky
