#Sex Differences in #Mathematics: A #Meta-analytic Review Across Content, Grades, and Geographic Regions | Educational Psychology Review |- #Gq #EDPSY #math #SLD #gender #schoolpsychology #schoolpsychologists

Quick email FYI research alert.  This is an open access downloadable article.  I always read anything math-related when David Geary is one of the authors.
 
Abstract 
 
The current meta-analysis of sex differences in mathematics builds upon the foun-dation laid by two large-scale analyses conducted years ago (e.g., Lindberg et al., 2010; Else-Quest et al., 2010). This meta-analysis provides a needed update and draws on a novel mix of studies, from experimental research to large-scale assess-ments, while offering a more detailed, current mapping of where, when, and in which mathematical domains sex differences emerge and change across grades. The review covers 2010 to 2022, and focuses on how sex differences in mathematics vary across grade level, mathematical content (e.g., arithmetic, geometry), geo-graphic region, and national levels of gender equality. Using PRISMA guidelines, we synthesized 440 studies with 1,210 effect sizes, encompassing over 15  million participants. Random-effects multilevel models revealed a small but significant overall male advantage (d = 0.08), with stronger effects emerging in later grades for geometry (d = 0.54) and broad mathematics (d = 0.26). These differences were more pronounced in countries with higher gender equality, as measured by indices such as the Global Gender Gap Index, and in regions such as Northern America, Europe and Central and South America. Results indicate that sex differences in mathemat-ics are content- and grade-specific, with a growing male advantage in later grades, especially in spatially intensive content areas like geometry. Overall, the findings support the role of both biological and socio-cultural factors in shaping sex differ-ences in mathematics and underscore the importance of targeted interventions to address these gaps in mathematical education.

Psychometrics and Linguistics in ChatGPT-Generated Reading Tests Compared with CET-4

Quick email FYI research alert post.  Not open access.
 
“The findings corroborate the conclusion that ChatGPT may function effectively as a supplementary tool in low-stakes assessment; however, substantial refinements in item quality are imperative before its application in high-stakes testing.”

Dr. Kevin McGrew’s update on MindHub web portal and IQs Corner blog - FYI and humble brag time

I’ve finally found time to perform some maintenance (e.g., fixing dead links; removing select info; updating posted articles; etc.) on my MindHub web portal.  I do the best I can as someone who has not stayed current on the ins-and-outs of web page work. The MindHub was originally developed by professional web people in 2012 and I try my best to maintain it on my own😉

Click on images to enlarge for easy viewing


My first internet presence is my IQs Corner blog that started in March 2005.  It has now been in existence for 21 years!  It can also be accessed at the MindHub.

As of today, IQs Corner, since Jan 2011, has had over 7.3 millions hits/visits!!  This number does not include the first five years of the blog (2005-2010) when I was extremely active in posting new material.  I believe that a reasonable estimate of total hits/visits is likely 10+ million. Thanks to all who have supported my 20+ years of blogging.

Below is the most recent graph of visits/hits.  Notice the recent significant spike in activity since I decided to pay more attention to IQs Corner circa 2024. I’m back!

I hope people find my sharing of information useful in their work.

Kevin “IQ” McGrew Twitter/X new “fresh start” account - now follow me at @iqmcgrew

 


My old twitter/X account (@iqmobile) was hacked.  I took it as an opportunity to “start fresh” with a better name.   Thus, I am now tweeting at @iqmcgrew.  

The old account is now dormant….but still viewable.  If you receive a “blocked” message it is not from me.  I’m liking the idea of a fresh chapter on X.  Build back better!

Test post ignore…new blog post /x trigger post check
