Learning Styles, Preferences, or Strategies? An Explanation for the Resurgence of Styles Across Many Meta-analyses - Educational Psychology Review The persistence of learning styles as a concept in educational discourse and research is paradoxical, given the overwhelming evidence discrediting the matching hypothesis, the notion that aligning…

See here for thorough and clear arguments for replacing "learning styles instruction" with instruction of learning strategies. Educators: teach content via multiple modalities. Learners: you don't have a single style; instead, learn to be adaptable in how you learn. #PsychSciSky #AcademicSky #EduSky

The Relation Between Perceived Mental Effort, Monitoring Judgments, and Learning Outcomes: A Meta-Analysis - Educational Psychology Review Accurately monitoring one’s learning processes during self-regulated learning depends on using the right cues, one of which could be perceived mental effort. A meta-analysis by Baars et al. (2020)…

Imagine going to the gym and thinking "lifting this heavy weight is hard, so lifting it is not making me stronger." Not how it works, right? Yet that's, in essence, how many students view mental effort and learning. Let's help students embrace mental effort. #PsychSciSky #AcademicSky #EduSky

This comment is the brief spiritual successor to our preprint (linked below) in which we argue much ado within debates over causal effects of social media stems from failing to account for the assumptions required by RCTs.

Agreed. I think of these as responses to increasingly impersonal systems that are designed for profit over care. Asking caregivers to take bare-bones scientific/medical advice and figure out alone how it applies to their own life creates a huge gap for grifters to exploit.

This Perspective is accompanied by a Correspondence by @jbakcoleman.bsky.social which argues that randomized controlled trials cannot identify social media’s causal effects

Ah good, now we have explicit virtue-laundering schemes to bolster the applications of well-resourced students.

This is fabulous! Great ideas for any type of science communication 🧪

One, of many, quotes from this article that stood out to me

"....we can train people to manage data, but unless there are career rewards or requirements for doing so, it won’t easily spread."

The dirty secret about causal inference is that the strongest assumptions are related to what you do not include. Unfortunately, it can be really hard to notice things that are not included.

Ian winning 2nd place in the Bounded Rationality Summer Institute Poster Competition

I was also honored to accept 2nd place in the poster competition for our poster "Testing the efficacy of combining misinformation interventions on influencing likelihood to share misinformation online" (say that ten times fast)!

It was an honor to attend the institute this year and learn from a diverse array of experts how we can research the interplay between humans and media environments.

I cannot wait to apply these new perspectives to my current and future work!

Are folks getting their NSF reinstated today? Some people said they received them back today, and I am trying to figure out how widespread this is.

Confounded or Controlled? A Systematic Review of Media Comparison Studies Involving Immersive Virtual Reality for STEM Education - Educational Psychology Review A substantial amount of media comparison research has been conducted in the last decade to investigate whether students learn Science, Technology, Engineering, and Mathematics (STEM) content better…

This article does a nice job describing the dos & do-not-dos of media comparison research. People wishing to compare e.g., ChatGPT v. traditional instruction would be wise to review the "Background on Technology in Education" section. #PsychSciSky #AcademicSky #EduSky doi.org/10.1007/s106...

👇👇👇 yes!! Lots of work explaining why this particular college is the best, very little about why the university sector as a whole is useful for society

Puns are for posters and symposium titles!

Many articles are written to be published, not to be read.

I propose this new badge to help me know when to save my breath.

NIH halts grant terminations ‘effective immediately,’ email says The National Institutes of Health is halting further terminations of research grants, an internal email shows

A major step in the right direction: thanks to all the researchers who shared news and the team at grant-watch.us (from @noamross.net & @scott-delaney.bsky.social and beyond) for their work to draw public attention to large-scale terminations....

Ok, @ryanenos.bsky.social and @stevelevitsky.bsky.social were able to calmly explain what I was failing to articulate earlier this week. Today's must read on why capitulating to authoritarian extortion is very very bad (and won't stop the attacks). Stay 💪 Harvard

If reliable information is behind paywalls, the vast majority of people will never have access to it.

They will have easy access to unreliable info and disinfo. But they won’t see anything other than headlines from reliable sources (and headlines are often misleading).

AI, peer review and the human activity of science When researchers cede their scientific judgement to machines, we lose something important.

New from me and @carlbergstrom.com in @nature.com on navigating LLMs in science, from the jumping off point of peer review.

If for no other reason, you should read our new paper on mixed methods in psychology because we managed to get limecat in there. doi.org/10.1177/2515...

Great new review on mixed-methods research in AMPPS! journals.sagepub.com/doi/10.1177/... Congrats to @syeducation.bsky.social and @dulcewestberg.bsky.social . We need more of this work across the different areas of psych science!

I am privileged to announce the publication of the Anti-Autocracy Handbook: sks.to/autocracy 1/12

Here’s @lkfazio.bsky.social doing a discussion for a disinformation symposium at @sarmac2025.bsky.social. She talked about the attacks on science and education. Lisa is a leader in standing up for science. Here she is talking about what we can do.

For the no kings day, from our conference overseas.

5. If as a community we confuse what is desirable for what is obtainable or if we suggest one might do well to throw out the environmental chemistry baby with the social psychology bathwater, it’s going to be very hard to for good science to withstand Daubert challenges.

That empowers corporations.
