Keep it simple: streamlining book illustrations improves attention and comprehension in beginning readers
https://www.nature.com/articles/s41539-020-00073-5 The study used a within-subject design with first- and second-grade children. Children (n = 60) read a story in a commercially available Standard condition and in a Streamlined condition, in which extraneous illustrations were removed while an eye-tracker recorded children’s gaze shifts away from the text, fixations to extraneous...
Testing the efficacy of three informational interventions for reducing misperceptions of the Black–White wealth gap
https://www.pnas.org/content/118/38/e2108875118 An intervention study exposed a US community sample to messages about Black–White racial inequality. Interventions including data bearing on Black–White wealth inequality elicited higher estimates of that inequality that persisted for at least 18 mo, aligning with federal data measuring the Black–White wealth gap. The data interventions also increased...
The First Rule of Machine Learning: Start without Machine Learning
https://eugeneyan.com/writing/first-rule-of-ml/ Guess what’s Rule #1 in Google’s 43 Rules of Machine Learning? Rule #1: Don’t be afraid to launch a product without machine learning. Machine learning is cool, but it requires data. Theoretically, you can take data from a different problem and then tweak the model for a new product,...

The relation between home numeracy practices and a variety of math skills in elementary school children
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0255400 A growing number of studies suggest that the frequency of numeracy experiences that parents provide at home may relate to children’s mathematical development. However, the relation between home numeracy practices and children’s numerical skills is complex and might depend upon both the type and difficulty of activities, as well...
Catering to learning styles isn't just ineffective: It can harm learning
https://www.learningscientists.org/blog/2021/9/16-1 The learning styles meshing hypothesis explains that individuals have preferred learning styles (e.g. auditory, visual, etc.) and that instruction that matches that preference will improve learning. This theory has no empirical evidence to support it and it’s a bit dangerous. I once had a student inform me that they...
Artificial Intelligence in Education (from Prodigy)
https://medium.com/prodigy-engineering/artificial-intelligence-in-education-8e9309aac08b AI Algorithms in Education There are many AI algorithms we can leverage to bring the aforementioned benefits. The algorithms here are a broader category of machine learning. Some of them will not require machine learning at all but using their machine learning or deep learning alternatives can increase the...
Secure human attachment can promote support for climate change mitigation
https://www.pnas.org/content/118/37/e2101046118 Attachment theory is an ethological approach to the development of durable, affective ties between humans. We propose that secure attachment is crucial for understanding climate change mitigation, because the latter is inherently a communal phenomenon resulting from joint action and requiring collective behavioral change. Here, we show that priming...
Individualistic culture increases economic mobility in the United States
https://www.pnas.org/content/118/37/e2107273118 Where an individual grows up has large implications for their long-term economic outcomes, including earnings and intergenerational mobility. Even within the United States, the “causal effect of place” varies greatly and cannot be fully explained by socioeconomic conditions. Across different nations, variation in growth and mobility have been linked...
Understanding the onset of hot streaks across artistic, cultural, and scientific careers
https://www.nature.com/articles/s41467-021-25477-8 Across a range of creative domains, individual careers are characterized by hot streaks, which are bursts of high-impact works clustered together in close succession. Yet it remains unclear if there are any regularities underlying the beginning of hot streaks. Here, we analyze career histories of artists, film directors, and...
