2 2 2 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

3 3 3 Raising achievement matters  For individuals  Increased lifetime salary  Improved health  For society  Lower criminal justice costs  Lower health-care costs  Increased economic growth

4 4 4 Where’s the solution?  Structure  Small high schools  K-8 schools  Alignment  Curriculum reform  Textbook replacement  Governance  Charter schools  Vouchers  Technology

5 5 5 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

6 6 6 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?

7 7 7 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

8 8 8 Cost/effect comparisons InterventionExtra months of learning/yr Cost/yr Class-size reduction by 30% (e.g., from 30 to 20) 3$30k Increase teacher content knowledge from weak to strong (2 standard deviations) 1.5? Formative assessment/ Assessment for learning 6 to 9$3k

9 9 9 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

10 10 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

11 11 Five Key Strategies … Questioning Engineering effective classroom discussions, questions, and learning tasks Feedback Moving learners forward with feedback Sharing Learning Expectations Clarifying and sharing learning intentions and criteria for success Self Assessment Activating students as the owners of their own learning Peer Assessment Activating students as instructional resources for one another

12 12 …and one big idea  Use evidence about learning to adapt instruction to meet student needs

13 13 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

14 14 Eliciting evidence of student achievement by engineering effective classroom discussions, questions and learning tasks

15 15 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]

16 16 Misconceptions

17 17 Misconceptions 3a = 24 a + b = 16

18 18 Molecular structure of water?

19 19 Moving learners forward with feedback

Psychol., 58 1-14] FeedbackGainAttitude scoresnonetop+ve bottom-ve comments30%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 Responses

22 22 [Butler (1987) J. Educ. Psychol. 79 474-482] 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)

23 23 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

24 24 Sharing learning intentions and success criteria Activating students as owners of their own learning Activating students as instructional resources for one another

25 25 [White & Frederiksen, Cognition & Instruction, 16(1), 1998]. 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

44 44 Techniques: feedback  Key idea: feedback should  cause thinking  provide guidance on how to improve  Comment-only grading  Focused grading  Explicit reference to mark-schemes and scoring guides  Suggestions on how to improve  ‘Strategy cards’ ideas for improvement  Not giving complete solutions  Re-timing assessment  (eg two-thirds-of-the-way-through-a-unit test)

45 45 Techniques: sharing learning intentions  Explaining learning intentions at start of lesson/unit  Learning intentions  Success criteria  Intentions/criteria in students’ language  Posters of key words to talk about learning  eg describe, explain, evaluate  Planning/writing frames  Annotated examples of different standards to ‘flesh out’ assessment rubrics (e.g. lab reports)  Opportunities for students to design their own tests

46 46 Practical techniques: peer and self-assessment  Students assessing their own/peers’ work  with rubrics  with exemplars  “two stars and a wish”  Training students to pose questions/identifying group weaknesses  Self-assessment of understanding  Traffic lights  Red/green discs  End-of-lesson students’ review

47 47 Putting it into practice

48 48 +– Force-field analysis (Lewin, 1951)  What kinds of forces present in your school/district will promote or support the development of this kind of work?  What kinds of forces present in your school/district will oppose or constrain the development of this kind of work?

49 49 A model for teacher learning  Content (what we want teachers to change)  Evidence  Ideas (strategies and techniques)  Process (how to go about change)  Choice  Flexibility  Small steps  Accountability  Support

50 50 Supporting Teachers and Schools to Change through Teacher Learning Communities

51 51 Implementing AfL requires changing habits, not adding knowledge  Teachers “know” most of this already  So the problem is not a lack of knowledge  It’s a lack of understanding what it means to do AfL  That’s why telling teachers what to do doesn’t work  Experience alone is not enough—if it were, then the most experienced teachers would be the best teachers—we know that’s not true (Hanushek, 2005)  People need to reflect on their experiences in systematic ways that build their accessible knowledge base, learn from mistakes, etc. (Bransford, Brown & Cocking, 1999)

52 52 That’s what TLCs are for:  TLCs contradict teacher isolation  TLCs reprofessionalize teaching by valuing teacher expertise  TLCs deprivatize teaching so that teachers’ strengths and struggles become known  TLCs offer a steady source of support for struggling teachers  They grow expertise by providing a regular space, time, and structure for that kind of systematic reflecting on practice  They facilitate sharing of untapped expertise residing in individual teachers  They build the collective knowledge base in a school

53 53 The synergy  Content: assessment for learning  Process: teacher learning communities  Components of a model  Initial workshops  Support for TLC leaders  Monthly TLC meetings  Peer observations  ‘Drip-feed’ resources  Web-site  Writings  New ideas

54 54 Summary  Raising achievement is important  Raising achievement requires improving teacher quality  Improving teacher quality requires teacher professional development  To be effective, teacher professional development must address  What teachers do in the classroom  How teachers change what they do in the classroom  AfL + TLCs  A point of (uniquely?) high leverage  A “Trojan Horse” into wider issues of pedagogy, psychology, and curriculum
