1. What kinds of assessments improve learning? Dylan Wiliam, ETS

2. Raising achievement matters For individuals –Increased lifetime salary –Improved health For society –Lower criminal justice costs –Lower health-care costs –Increased economic growth

3. Where’s the solution? Structure –Small high schools –K-8 schools Alignment –Curriculum reform –Textbook replacement Governance –Charter schools –Vouchers Technology

4. 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

5. 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?

6. The design challenge Key metric: –Cost of buying one standard deviation of increased student achievement Constraints –Solution must be in principle scalable

7. Cost/effect comparisons InterventionEffect (sd) Cost/yr Class-size reduction (by 30%) 0.1$24k Increase teacher content knowledge by 1 sd 0.1? Formative assessment/ Assessment for learning 0.2<$1k

8. Effects of formative assessment Several major reviews of the research –Natriello (1987) –Crooks (1988) –Black & Wiliam (1998) –Nyquist (2003) All find consistent, substantial effects

9. 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 size 0.4, but –Effect sizes very variable –40% of effect sizes were negative

10. Kinds of feedback (Nyquist, 2003) Weaker feedback only –Knowledge of results (KoR) Feedback only –KoR + clear goals/knowledge of correct results (KCR) Weak formative assessment –KCR+ explanation (KCR+e) Moderate formative assessment –(KCR+e) + specific actions for gap reduction Strong formative assessment –(KCR+e) + activity

12. Feedback and formative assessment “Feedback is information about the gap between the actual level and the reference level of a system parameter which is used to alter the gap in some way” (Ramaprasad, 1983 p. 4) Formative assessment requires –data on the actual level of some measurable attribute; –data on the reference level of that attribute; –a mechanism for comparing the two levels and generating information about the ‘gap’ between the two levels; –a mechanism by which the information can be used to alter the gap.

13. Formative assessment Frequent feedback is not necessarily formative Feedback that causes improvement is not necessarily formative Assessment is formative only if the information fed back to the learner is used by the learner in making improvements To be formative, assessment must include a recipe for future action

14. Assessment for learning & formative assessment (Black et al., 2002) Assessment for learning is any assessment for which the first priority in its design and practice is to serve the purpose of promoting pupils’ learning. It thus differs from assessment designed primarily to serve the purposes of accountability, or of ranking, or of certifying competence. An assessment activity can help learning if it provides information to be used as feedback, by teachers, and by their pupils, in assessing themselves and each other, to modify the teaching and learning activities in which they are engaged. Such assessment becomes ‘formative assessment’ when the evidence is actually used to adapt the teaching work to meet learning needs.

15. Feedback Feedback is therefore formative only if the information fed back is actually used in closing the gap. Three key instructional processes –Establishing where learners are in their learning –Establishing where they are going –Establishing how to get there

16. Aspects of formative assessment Where the learner is going Where the learner is How to get there Teacher Clarify learning intentions Engineering effective discussions Providing feedback that moves learners on Peer Understand/ clarify criteria for success Activating students as instructional resources for one another Learner Understand criteria for success Activating students as owners of their own learning

17. Five key strategies… Clarifying and understanding learning intentions and criteria for success Engineering effective classroom discussions that elicit evidence of learning Providing feedback that moves learners forward Activating students as instructional resources for each other Activating students as the owners of their own learning

18. …and one big idea Use evidence about learning to adapt instruction to meet student needs

19. 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. Educational systems must do the same: –Plan a carefully chosen route ahead of time (in essence building the track) –Take readings along the way –Change course as conditions dictate

20. Regulation of learning Teaching as engineering learning environments Key features: –Create student engagement (pedagogies of engagement) –Well-regulated (pedagogies of contingency) Long feedback cycles vs. variable feedback cycles Quality control vs. quality assurance in learning Teaching vs. learning Regulation of activity vs. regulation of learning

21. Regulation of learning Proactive (upstream) regulation –Planning regulation into the learning environment –Planning for evoking information Interactive (downstream) regulation –‘Negotiating the swiftly-flowing river’ –‘Moments of contingency’ –Tightness of regulation (goals vs. horizons) Retrospective regulation –Structured reflection (e.g., lesson study)

22. Types of formative assessment Long-cycle –Focus: between units –Length: four weeks to one year Medium-cycle –Focus: within units, between lessons –Length: one day to two weeks Short-cycle –Focus: within lessons –Length: five seconds to one hour

33. Why research hasn’t changed teaching Misunderstanding nature of teacher expertise Leaving teachers to “translate into practice” Failure to attend to both content and process

34. Klein & Klein (1981) Six video extracts of someone delivering cardio-pulmonary resuscitation (CPR) –5 of the videos are of CPR students –1 of the videos is of an expert paramedic Videos shown to three groups: –students, instructors and experts Success rate in identifying expert: –Experts: 90% –Students: 50% –Instructors: 30%

35. Teacher expertise (Berliner, 1994) –Experts excel mainly in their own domain –Experts often develop automaticity for the repetitive operations that are needed to accomplish their goals –Experts are more sensitive to the task demands and social situation when solving problems. –Experts are more opportunistic and flexible in their teaching than novices –Experts represent problems in qualitatively different ways than novices. –Experts have fast and accurate pattern recognition capabilities. Novices cannot always make sense of what they experience. –Experts perceive meaningful patterns in the domain in which they are experienced. –Experts begin to solve problems slower, but bring richer and more personal sources of information to bear on the problem that they are trying to solve.
