4. Quart de couverture

"Hattie’s book is designed as a meta-meta-study that collects, compares and analyses the findings of many previous studies in education. Hattie focuses on schools in the English-speaking world but most aspects of the underlying story should be transferable to other countries and school systems as well.

Visible Learning is nothing less than a synthesis of more than 50.000 studies covering more than 80 million pupils. Hattie uses the statistical measure effect size to compare the impact of many influences on students’ achievement, e.g. class size, holidays, feedback, and learning strategies.

The following examples may give an impression of the scope of Hattie’s findings:

  • What’s bad? Retention, summer holidays
  • What’s neither bad nor good? Team teaching, open vs. traditional classes
  • What helps a bit? Class size, homework
  • What helps a bit more? Cooperative learning, direct instruction
  • What helps a lot? Feedback, Student-teacher relationships" (Source : http://visible-learning.org)
