Excited to share a new paper from UD's Early Fraction Understanding Project! We identified three latent profiles of informal fraction knowledge in first grade, each with relative strengths in their understanding of fraction concepts. Profile membership predicted cognitive skills and math knowledge.

Profiles of fraction knowledge in first grade and their relation to cognitive and mathematical skills
Latent profile analysis was used to examine variation in early fraction knowledge among first graders (N = 204; Mage = 6.68 years) across nonsymbolic …

My 1st research experience was as an undergrad psych student at CUNY Lehman College in the Bx. I joined the Louis Stokes Alliances for Minority Participant in STEM. I would not have pursued academia if I hadn’t participated in that NSF-funded program. I REALLY hope it’s not on the chopping block 💔
Exclusive: NSF this week began to search through billions of dollars of grants the agency has already awarded for anything touching on topics that President Donald Trump has criticized. And NSF has blocked grantees and trainees from accessing funds while the review is underway. scim.ag/3El0NZh
EXCLUSIVE: NSF starts vetting all grants to comply with Trump’s orders
Grantee accounts remain frozen, while union accuses NSF of ignoring rules governing peer review
