| People questioning the headline are missing the point of the underlying article. The underlying study is not about just rate of learning, but rate of learning under favorable conditions. The article describes where the data comes from: > In particular, we model learning using 27 datasets with over 1.3 million student performance observations from 6,946 learners in 12 different courses ranging across math, science, and language learning, across educational levels from late elementary to college, and across educational technologies including intelligent tutoring systems, educational games, and online courses And the authors argue this is favorable learning conditions because of providing things like immediate feedback on errors, etc.. Lots of room for nuance, but "favorable learning conditions" is key here. https://www.pnas.org/doi/10.1073/pnas.2221311120 |
