Throughout Dr. Steve Yussen’s career, he’s been interested in studying children’s memory and learning, particularly as it relates to reading and comprehension. In these and other areas of educational psychology there’s been a large base of research accumulated, but how much of it is really accurate for children around the world? Based on a study of three of the world’s leading journals of educational psychology, he found a troubling bias towards the publication of studies based in first-world, English-speaking countries and European countries with English language reports (e.g., French, German, Spanish). This means that much of what is considered “facts” and best practices in educational psychology may not apply to a vast majority of the world’s children. In short, it’s very possible that we don’t know nearly as much as we think we do.
