An update: this fall, I’ll be joining @UDSOE within @UDCEHD as an Assistant Professor in the Educational Statistics and Research Methods program. I could not be more excited!

Wyatt Read presented this work today at the UD Steele Symposium!

In anticipation of IOMW 2025, we’ve posted a preprint of the paper we’ll be discussing there. Take a look! https://t.co/8kf2nMEpy0

Ever wanted to investigate DIF by more than one variable at once? My colleague Ethan McCormick and I have created an NCME ITEMS module on DIF analysis with multiple background variables using moderated nonlinear factor analysis. Take a look! https://t.co/Q6K3Mr1AKZ

Out now: @DerekCBriggs,
Laurie Davis and I investigate differences in how much students appear to grow on a vertical scale based solely on the grade alignment of (a large number of) common items. Turns out, the differences are pretty big!

@DrTeyaR My favorite was the obviously AI-generated negative evaluation of our proposal that the reviewer pasted in ��

@MatthewBJane what’s old is new again, ha! But like you’ve said it really has its uses, eg early in item analysis, so I’m all for re-popularizing it. I’m no expert on nonparametric IRT but this seems like the sort of thing that would be very useful for eg Mokken scaling

[Sandy Student @sandy_student]

@MatthewBJane I think this is sometimes called a Guttman chart, in reference to a Guttman scale and the process of scalogram analysis. The more consistent the relationship between item p and person p, the more “scalable” the items (to use the Guttman terminology).

🗣️🗣️🗣️A good article and another PSA on why translating effect sizes into years or days of learning is a bad idea (in most cases). https://t.co/akz5OYdwcj

[Sandy Student @sandy_student]

@wesbonifay I’m not really in any sort of position to critique this paper and I know that philosophy can fruitfully investigate all sorts of questions that on their face sound absurd. But I also had to make this

[Sandy Student @sandy_student]

@wesbonifay I’m three paragraphs in and have already had to google one word with no apparent definition or use beyond the paper

[Sandy Student @sandy_student]

Not sure who is still on here but new article day! Follow the link for updated benchmarks for grade 3-8 annual growth and an investigation of what drives the considerable variability in growth across different scales. https://t.co/Kdq3pLG11E

Come be my colleague! We are hiring for a TT assistant professor in education statistics and data science. Please get in touch with any questions! https://t.co/m1UxIszbTJ

@KlintKanopka @TracyMSweet I’ll take one pls

I’ve officially started @UDSOE ! Here’s my terrible picture of a great rendition of the Blue Hen 😆

[Sandy Student @sandy_student]

@wesbonifay The other option I considered was The Silmarillion, unsure why I am like this

[Sandy Student @sandy_student]

@wesbonifay Was trying to recall how I became aware of Stoner, then somehow remembered that it was this tweet. Pretty much the worst beach book imaginable, but I really loved it. Thank you!
