In this book Dylan Wiliam stresses the importance of formative assessment as a key process for increasing teacher quality whilst having the biggest impact on student outcomes. He argues that quality of teachers is the single most important factor in the education system. He looks at some of the popular initiatives that aim to increase student achievement, such as learning styles, and presents research that shows formative assessment practices have a much greater impact on educational achievement than most other reforms. This book offers over fifty practical techniques for classroom formative assessment that every teacher will be able to implement into their regular classroom practice. Formative assessment strategies include classroom questioning, learning intentions, productive feedback and collaborative learning.
