Classroom assessment:minute-by-minute and day-to-day Session 1249T: ASCD Annual Conference 2007 17 March 2007; Anaheim, CA Dylan Wiliam, Institute of Education, University of London www.dylanwiliam.net
Overview of presentation • Why raising achievement is important • Why investing in teachers is the answer • Why assessment for learning should be the focus • Why teacher learning communities should be the mechanism • How we can put this into practice
Raising achievement matters • For individuals • Increased lifetime salary • Improved health • For society • Lower criminal justice costs • Lower health-care costs • Increased economic growth
Where’s the solution? • Structure • Small high schools • K-8 schools • Alignment • Curriculum reform • Textbook replacement • Governance • Charter schools • Vouchers • Technology
It’s the classroom • Variability at the classroom level is up to 4 times greater than at school level • It’s not class size • It’s not the between-class grouping strategy • It’s not the within-class grouping strategy • It’s the teacher
Teacher quality • A labor force issue with 2 solutions • Replace existing teachers with better ones? • No evidence that more pay brings in better teachers • No evidence that there are better teachers out there deterred by certification requirements • Improve the effectiveness of existing teachers • The “love the one you’re with” strategy • It can be done • We know how to do it, but at scale? Quickly? Sustainably?
Why assessment for learning? • Several major reviews of the research • Natriello (1987): grades K-12 • Crooks (1988): grades K-12 • Kluger & DeNisi (1996): grades K-16, work • Black & Wiliam (1998): K-12 • Nyquist (2003): grades 13-16 • All find consistent, substantial effects
Types of formative assessment • Long-cycle • Span: across units, terms • Length: four weeks to one year • Medium-cycle • Span: within and between teaching units • Length: one to four weeks • Short-cycle • Span: within and between lessons • Length: • day-by-day: 24 to 48 hours • minute-by-minute: 5 seconds to 2 hours
Effects of formative assessment • Long-cycle • Student monitoring • Curriculum alignment • Medium-cycle • Improved, student-involved, assessment • Improved teacher cognition about learning • Short-cycle • Improved classroom practice • Improved student engagement
…and one big idea • Use evidence about learning to adapt instruction to meet student needs
Keeping Learning on Track (KLT) • A pilot guides a plane or boat toward its destination by taking constant readings and making careful adjustments in response to wind, currents, weather, etc. • A KLT teacher does the same: • Plans a carefully chosen route ahead of time (in essence building the track) • Takes readings along the way • Changes course as conditions dictate
Eliciting evidence of student achievement by engineering effective classroom discussions, questions and learning tasks
Kinds of questions: Israel Which fraction is the smallest? Success rate 88% Which fraction is the largest? Success rate 46%; 39% chose (b) [Vinner, PME conference, Lahti, Finland, 1997]
Misconceptions 3a = 24 a + b = 16
Kinds of feedback: Israel • 264 low and high ability grade 6 students in 12 classes in 4 schools; analysis of 132 students at top and bottom of each class • Same teaching, same aims, same teachers, same classwork • Three kinds of feedback: scores, comments, scores+comments Feedback Gain Attitude scores none top +ve bottom -ve comments 30% all +ve [Butler(1988) Br. J. Educ. Psychol., 58 1-14]
Responses Feedback Gain Attitude scores none top +ve bottom -ve comments 30% all +ve What do you think happened for the students given both scores and comments: A: Gain: 30%; Attitude: all +ve B: Gain: 30%; Attitude: top +ve, bottom -ve C: Gain: 0%; Attitude: all +ve D: Gain: 0%; Attitude: top +ve, bottom -ve E: Something else [Butler(1988) Br. J. Educ. Psychol., 58 1-14]
Kinds of feedback: Israel (2) • 200 grade 5 and 6 Israeli students • Divergent thinking tasks • 4 matched groups • experimental group 1 (EG1); comments • experimental group 2 (EG2); grades • experimental group 3 (EG3); praise • control group (CG); no feedback • Achievement • EG1>(EG2≈EG3≈CG) • Ego-involvement • (EG2≈EG3)>(EG1≈CG) [Butler (1987) J. Educ. Psychol.79 474-482]
Effects of feedback • Kluger & DeNisi (1996) • Review of 3000 research reports • Excluding those: • without adequate controls • with poor design • with fewer than 10 participants • where performance was not measured • without details of effect sizes • left 131 reports, 607 effect sizes, involving 12652 individuals • Average effect of feedback substantial, but • Effect sizes very variable • 40% of effect sizes were negative
Sharing learning intentions and success criteriaActivating students as owners of their own learningActivating students as instructional resources for one another
Student involvement in learning • 3 teachers each teaching 4 year 8 science classes in two US schools • 14 week experiment • 7 two-week projects, scored 2-10 • All teaching the same, except: • For a part of each week • Two of each teacher’s classes discusses their likes and dislikes about the teaching (control) • The other two classes discusses how their work will be assessed [White & Frederiksen, Cognition & Instruction, 16(1), 1998].

Techniques: questioning • Key idea: questioning should • cause thinking • provide data that informs teaching • Improving teacher questioning • generating questions with colleagues • closed v open • low-order v high-order • appropriate wait-time • Getting away from I-R-E • basketball rather than serial table-tennis • ‘No hands up’ (except to ask a question) • class polls to review current attitudes towards an issue • ‘Hot Seat’ questioning • All-student response systems • ABCD cards, Mini white-boards, Exit passes
Questioning in math: discussion Look at the following sequence: 3, 7, 11, 15, 19, …. Which is the best rule to describe the sequence? • n + 4 • 3 + n • 4n - 1 • 4n + 3

Questioning in science: discussion Ice-cubes are added to a glass of water. What happens to the level of the water as the ice-cubes melt? • The level of the water drops • The level of the water stays the same • The level of the water increases • You need more information to be sure
Questioning in science: diagnosis The ball sitting on the table is not moving. It is not moving because: • no forces are pushing or pulling on the ball. • gravity is pulling down, but the table is in the way. • the table pushes up with the same force that gravity pulls down • gravity is holding it onto the table. • there is a force inside the ball keeping it from rolling off the table Wilson & Draney, 2004
Save the ozone layer What can we do to preserve the ozone layer? • Reduce the amount of carbon dioxide produced by cars and factories • Reduce the greenhouse effect • Stop cutting down the rainforests • Limit the numbers of cars that can be used when the level of ozone is high • Properly dispose of air-conditioners and fridges
