Hi @flavinska.bsky.social ! I’m a little late in working on my submission. I recall there being an excel sheet in the past with symposia in development last time it was in DC. Is that a thing this year? Where can I find that if so?

As Dr. Chawla explains, the 0–100 number line estimation task is widely used to study children’s numerical magnitude understanding. Along w/Dr. @juliebooth.bsky.social we asked a practical measurement question: What is the optimal number of items needed to retain the task’s utility? See new 📄 in JNC

An ed psych journal is refusing to publish our manuscript unless we "neutralize" "political" content. This is after the manuscript was peer-reviewed and accepted for publication. DM me for details!
