Overview of presentationWhy raising achievement is importantWhy investing in teachers is the answerWhy formative assessment should be the focusWhy teacher learning communities should be the mechanismHow we can put this into practice
Raising achievement mattersFor individuals Increased lifetime salary Improved healthLonger lifeFor societyLower criminal justice costsLower health-care costs Increased economic growth
Where’s the solution?Structure Smaller high schools K-8 schoolsAlignmentCurriculum reform Textbook replacementGovernanceCharter schools VouchersTechnologyComputers Interactive white-boards
School effectivenessThree generations of school effectiveness researchRaw results approaches
Different schools get different results Conclusion: Schools make a difference
Demographic-based approaches Demographic factors account for most of the variation Conclusion: Schools don’t make a difference
Value-added approaches School-level differences in value-added are relatively small Classroom-level differences in value-added are large Conclusion: An effective school is a school full of effective classrooms
How important is teacher quality?How much progress will an average student make when taught by a great teacher (i.e., the best teacher in a group of 50)?
A. An extra month per yearB. An extra two months per yearC. An extra three months per yearD. An extra four months per yearE. An extra six months per year
Teacher qualityA labor force issue with 2 solutionsReplace 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
burdensome 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?
20-25%Total “explained” difference
<5%Further professional qualifications (NBPTS)
10-15%Pedagogical content knowledge

The research evidenceSeveral major reviews of the researchNatriello (1987)Crooks (1988)Kluger & DeNisi (1996)Black & Wiliam (1998)Nyquist (2003)All find consistent, substantial effects
Types of formative assessmentLong-cycleSpan: across units, terms Length: four weeks to one year Impact: Student monitoring; curriculum alignmentMedium-cycleSpan: within and between teaching units Length: one to four weeks Impact: Improved, student-involved, assessment; teacher cognition about learningShort-cycleSpan: within and between lessons Length:
day-by-day: 24 to 48 hours minute-by-minute: 5 seconds to 2 hours
Impact: classroom practice; student engagement
Unpacking formative assessmentKey processesEstablishing where the learners are in their learningEstablishing where they are goingWorking out how to get there
ParticipantsTeachersPeersLearners
Aspects of formative assessmentWhere the learner
is going Where the learner is How to get there
Teacher Clarify and share learning intentions
Engineering effective discussions, tasks and
activities that elicit evidence of learning
Providing feedback that moves learners
forward
PeerUnderstand and share learning
intentions
Activating students as learningresources for one another
Learner Understand learning intentions
Activating students as ownersof their own learning
Sharing learning intentions
Explaining learning intentions at start of lesson/unitLearning intentionsSuccess criteriaIntentions/criteria in students’ languagePosters of key words to talk about learningeg describe, explain, evaluatePlanning/writing framesAnnotated examples of different standards to ‘flesh out’ assessment rubrics (e.g. lab reports)Opportunities for students to design their own tests
Eliciting evidence of achievementKey idea: questioning should cause thinking provide data that informs teachingImproving teacher questioning generating questions with colleagues closed vs. open or low-order vs. high-order appropriate wait-timeGetting away from I-R-E basketball rather than serial table-tennis ‘No hands up’ (except to ask a question) ‘Hot Seat’ questioningAll-student response systemsABCD cards, Mini white-boards, Exit passes
Feedback that moves learning onKey idea: feedback should
cause thinking provide guidance on how to improve
Comment-only gradingFocused gradingExplicit reference to mark-schemes and scoring guidesSuggestions 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)
Students as owners of their learningStudents assessing their own work with rubricswith exemplarsSelf-assessment of understandingTraffic lightsRed/green discsColored cups
Students as instructional resourcesStudents assessing their peers’ work “pre-flight check-list”“two stars and a wish”Training students to pose questions/identifying group weaknessesEnd-of-lesson students’ review
…and one big ideaUse evidence about learning to adapt teaching and learning 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
Putting it into practice
Implementing FA/AfL requires changing teacher habitsTeachers “know” most of this alreadySo the problem is not a lack of knowledgeIt’s a lack of understanding what it means to do FA/AfLThat’s why telling teachers what to do doesn’t workExperience 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; Day, 2006) People need to reflect on their experiences in systematic ways that build their accessible knowledge base, learn from mistakes, etc. (Bransford, Brown & Cocking, 1999)

Teacher learning takes timeTo put new knowledge to work, to make it meaningful and accessible when you need it, requires practice.A teacher doesn’t come at this as a blank slate. Not only do teachers have their current habits and ways of teaching—
they’ve lived inside the old culture of classrooms all their lives: every teacher started out as a student!
New knowledge doesn’t just have to get learned and practiced, it has to go up against long-established, familiar, comfortable ways of doing things that may not be as effective, but fit within everyone’s expectations of how a classroom should work.
It takes time and practice to undo old habits and become graceful at new ones. Thus… Professional development must be sustained over time
That’s what teacher learning communities (TLCs) are for:
TLCs contradict teacher isolationTLCs reprofessionalize teaching by valuing teacher expertiseTLCs deprivatize teaching so that teachers’ strengths and struggles
become knownTLCs offer a steady source of support for struggling teachersThey grow expertise by providing a regular space, time, and structure
for that kind of systematic reflecting on practiceThey facilitate sharing of untapped expertise residing in individual
teachersThey build the collective knowledge base in a school
How to set up a TLCPlan that the TLC will run for two yearsIdentify 8 to 10 interested colleaguesShould have similar assignments (e.g. early years, math/sci)Secure institutional support for:Monthly meetings (75 to 120 minutes each, inside or outside school time)Time between meetings (2 hrs per month in school time)
Collaborative planning Peer observation
Any necessary waivers from school policies
A ‘signature pedagogy’ for teacher learning?Every monthly TLC meeting should follows the same structure and sequence of activities
Activity 1: Introduction & Housekeeping (5-10 minutes)Activity 2: How’s It Going (35-50 minutes)Activity 3: New Learning about AfL (20-45 minutes)Activity 4: Personal Action Planning (10 minutes)Activity 5: Summary of Learning (5 minutes)
The TLC leader’s roleTo ensure the TLC meets regularlyTo ensure all needed materials are at meetingsTo ensure that each meeting is focused on AfL To create and maintain a productive and non-judgmental tone during meetings To ensure that every participant shares with regard to their implementation of AfL To encourage teachers to provide their colleagues with constructive and thoughtful feedbackTo encourage teachers to think about and discuss the implementation of new AfL learning and skillsTo ensure that every teacher has an action plan to guide their next stepsBut not to be the AfL “expert”
Peer observationRun to the agenda of the observed, not the observerObserved teacher specifies focus of observationObserve teacher specifies what counts as evidencee.g., teacher wants to increase wait-timeprovides observer with a stop-watch to log wait-times
