There are now 1,332 published Ofsted reports that use the new report card framework (5th May). Here are a few key takeaways from the data so far 📊👇 📉 The biggest challenge: "Achievement" remains the area with the highest percentage of "Needs Attention" and "Urgent Improvement" grades. #ofsted

Just released mori 0.1.0 on CRAN — a new R package for shared memory across processes. Parallel R no longer has to mean duplicating your dataset in every worker's RAM. opensource.posit.co/blog/2026-04... 🧵 1/3

mori: Shared memory for R objects

mori is a new R package for sharing R objects across processes via OS-level shared memory. Parallel workers get zero-copy, lazy ALTREP access to the same physical pages — share once, read anywhere.

Cleaning some #ofsted data for a publication. The new report cards are tougher than TES reported in January, when they stated: > 1 in 7 schools in first wave gets ‘exceptional’ grade [14.2%] ... no school has given the lowest grade of ‘urgent improvement’

🎯 New open access paper: What do school websites signal about computing and who it is for? Using document data (n = 960), we examine how schools frame computer science in public-facing materials, and what that might mean for gendered participation. www.tandfonline.com/doi/full/10....

Marketing computing: how school branding reinforces or challenges gender stereotypes

This paper examines how school branding and policy may shape gender disparities in computing education. Wong et al. explore how schools portray computing in brochures, websites and related material...

These look like some very useful updates!

dplyr 1.2.0

dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and replacing functions!

Thinking about odds ratios... An odds is a ratio of events to non-events. For example, if the event is survival, the odds of survival is the number of survivors per death. If the event is getting a disease, the odds is the number of diseased individuals per healthy individual.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

If you are preparing your bachelor statistics course and would like to add optional material for students to better understand statistics on a conceptual level (see topics in the screenshot) my free textbook provides a state of the art overview. lakens.github.io/statistical_...

I’m about halfway through this update (first 11 tutorials are done). I think they’re a lot better. Using a consistent @easystats.github.io workflow throughout will - I think - massively reduce the cognitive load for students. Looking forward to road testing in autumn term.

Probably no-one except me uses my R tutorials in their teaching, but if you do, I'm re-writing them over the next 6-9 months. My goal is to streamline them based on 5 years of using them in class, but if you have (polite) requests/suggestsions let me have them. www.discovr.rocks/discovr/

When teaching at UCLA, I always start with this principle: “All models are wrong, but some are useful.” The key is knowing how a model is wrong—bias, variance, scope—and when it still adds value. #DataScience #MachineLearning #AI #RStats

Today is my annual reminder that read_csv() is vectorized and you can just pass a vector of file paths and it will read and append the datasets. No need to use map or for loops to read in multiple files. #rstats

US CS degrees 1964-2022, female uptake getting better for bachelor degrees (peak 1984), MA and PhD have never been as well balanced as now (from a low base) #rstats #DataScience #python #csed #edusky

when they close it all up, I do believe this will go down as the funniest video on the internet

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Julia M. Rohrer@dingdingpeng.the100.ci · last yr.

Does anybody have a good visualization to explain how interactions can be confounded, and why interactions require interaction controls? @urisohn.bsky.social maybe? (Asking because I have an idea, but want to check out what exists already before investing the effort)

🚨 All staff for NSF’s Division of Equity for Excellence in STEM (EES) have just been fired. In email to grantees: “the entire Division of Equity for Excellence in STEM has just been dissolved and the entire staff fired.” High time for scientists, public, Congress, YOU to take action to #SaveNSF
