Referencing a principle from author G.K. Chesterton (to not reform a policy unless you know its original purpose), Wiliam argues that before we make changes to long-established grading practices, we must know the reasons those practices are favored by many teachers, and what benefits the practice may have. He explores why three grading…

In this "Open Dialogue: Peer Response," the author notes that in the initial paper, "Contributions of Educational Psychology to Understanding Student Learning: What Has Been Discovered - What More Could Be Done?" Entwistle lays out a useful summary of the way that psychology has contributed to an understanding of student…

With teacher and leader workloads and burnout at an all-time high, it's time for de-implementation: de-prioritizing and deleting the less effective, higher-cost initiatives we implement in schools. De-implementation allows us to focus on practices that have more supporting evidence and a higher probability of positive impact on students, and at…

In this article, Dylan William states that the central claim in Baird, et al.'s piece is that if theories of assessment take into account theories of learning, assessments will somehow be more valid, and some of the more egregious effects of assessment on learning will be ameliorated. William responds to this claim by arguing that it seems…

"The only important thing about feedback is what students do with it," declares Dylan Wiliam in this article. The standard school procedure (in which a teacher looks at a piece of student work and writes something on it, and the student later looks at what the teacher has written) does not necessarily increase student learning. Teachers…

Since our 1998 review of research on classroom assessment and learning was published, we have contributed to theorising formative assessment, but recognise that this work is incomplete. In this paper, we take up a suggestion by Perrenoud that any theory of formative assessment must be embedded within a wider theoretical field, specifically, within…

According to author Dylan Wiliam, because lessons never go exactly as planned, teachers should build plan B into plan A. This involves designing a lesson with a "hinge" somewhere in the middle and using specific kinds of questions--what he calls hinge questions--to quickly assess students' understanding of a concept before moving on.…

According to Dylan Wiliam, the traditional classroom practice in which a teacher asks a question, students raise their hands, and the teacher calls on a volunteer does not actually provide much useful information--and it may even impede learning. When teachers ask questions in this way, they're only engaging the most confident students in the…

In "How Is Testing Supposed to Improve Schooling?" Edward Haertel has proposed a framework for thinking about the mechanisms by which testing might improve the various educational processes undertaken in schools. The framework seems to the author to be quite general (he uses the word "general" here in its mathematical sense of including all cases)…

The accuracy of the results of the national tests in English, mathematics and science taken by 11-year olds in England has been a matter of much debate since their introduction in 1994, with estimates of the proportion of students incorrectly classified varying from 10 to 30%. Using live data from the 2009 and 2010 administration of the national…

In this article, I try to make pedagogical adaptability a bit less obvious. In particular, I use some post-structural philosophical ideas and some concepts at the intersections of social class and race to re-interpret Dylan Wiliam's conception of formative assessment. I suggest that this interpretation can provide opportunities to resist the urge…

Twenty years after the publication of "Inside the Black Box," the landmark review of formative classroom assessment, international education experts Christine Harrison and Margaret Heritage tackle assessment for learning (AfL) anew, with fresh insights gained from two decades of research, theory, and classroom practice. "The Power…

By integrating classroom formative assessment practices into daily activities, educators can substantially increase student engagement and the rate of student learning. The second edition of this best-selling book by Dylan Wiliam presents new research, insights, and formative assessment strategies and techniques teachers can immediately apply in…

In partnership with Joint School District 2 in Meridian, Idaho, this theory-driven study assessed the impact of Keeping Learning on Track® (KLT™), a professional development program pioneered by Dylan Wiliam and his colleagues at the Educational Testing Service (ETS). A team of Northwest Evaluation Association™ (NWEA™) researchers surveyed…

Marge Scherer describes this issue of "Educational Leadership" as being all about questioning for learning--how to ask questions of students, how to encourage students to ask their own questions, and how to ask better questions and find better answers. Among feature topics explored in this issue are why children, who start questioning…
