Visible Learning : Routledge : 9781032462028 : 1032462027 : 20 Mar 2023 : When the original Visible Learning® was published in 2008, it instantly became a publishing sensation. Interest in the book was unparalleled; it sold out in days and was described by the TES as revealing "teaching's Holy Grail". Now John Hattie returns to this ground-breaking work. The research underlying this book is now informed by more than 2,100 meta-analyses (more than double that of the original), drawn from more than 130,000 studies, and has involved more than 400 million students from all around the world. But this is more than just a new edition.
