Overview of presentationWhy raising achievement is important

Why investing in teachers is the answer

Why formative assessment should be the focus

Why teacher learning communities should be the mechanism

How we can put this into practice

Why, what & how?

Raising achievement mattersFor individuals Increased lifetime salary Improved healthLonger life

For societyLower criminal justice costsLower health-care costs Increased economic growth

Why?

Where’s the solution?Structure Smaller schools/larger schools Middle schools/getting rid of middle schools

Alignment Curriculum reform Textbook replacement

Governance Specialist schools Academies

Technology Computers Interactive white-boards

Why?

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

Why?

It’s the classroomVariability at the classroom level is up to 4 times that 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

Why?

Teacher qualityA labour 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?

All find consistent, substantial effects

Aspects of formative assessment

Where the learner is How to get there

TeacherClarify 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

LearnerUnderstand

learning intentionsActivating students as owners

of their own learning

Five “key strategies”…Clarifying, understanding, and sharing learning intentionscurriculum philosophy

Engineering effective classroom discussions, tasks and activities that elicit evidence of learningclassroom discourse, interactive whole-class teaching

Providing feedback that moves learners forward feedback

Activating students as learning resources for one another collaborative learning, reciprocal teaching, peer-assessment

Activating students as owners of their own learningmetacognition, motivation, interest, attribution, self-assessment

(Wiliam & Thompson, 2007)

…and one big ideaUse evidence about learning to adapt teaching and learning to meet student needs

What?

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

What?

Putting it into practice

Implementing FA/AfL requires changing teacher habitsTeachers “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 FA/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; 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) How?

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

How?

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?

King’s-Medway-Oxfordshire Formative Assessment Project“Polyexperiment” design24 teachers, each developing their practice in individual waysEach teacher chose which class to explore these ideas withEach teacher chose how to measure successDifferent outcome variables, so no possibility of standardized controlsSynthesis by standardized effect sizeImpact on student achievement0.3 standard deviations (i.e., about 8 months extra learning per year)Other small-scale replications (Hayes, 2003; Clymer 2007) find similar

effects

How?

Taking it to scale

How to set up a TLCPlan that the TLC will run for two years

Identify 8 to 10 interested colleaguesShould have similar assignments (e.g. early years, math/sci)

Secure institutional support for:Monthly meetings (2 hrs 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

How?

A ‘signature pedagogy’ for teacher learning?Every monthly TLC meeting should follows the same structure and sequence of activities

Activity 1: Introduction & Housekeeping (5 minutes)

Activity 2: How’s It Going (50 minutes)

Activity 3: New Learning about AfL (50 minutes)

Activity 4: Personal Action Planning (10 minutes)

Activity 5: Summary of Learning (5 minutes)

How?

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”

How?

Peer observationRun to the agenda of the observed, not the observer

Observed teacher specifies focus of observation

Observe teacher specifies what counts as evidencee.g., teacher wants to increase wait-timeprovides observer with a stop-watch to log wait-times

How?

“Tight but loose”

Tight about Teacher choice Strategies “How’s it going?” & action planning Size of TLC

Loose about Timing and location of meetings Techniques New learning about AfL Make-up of TLC

… combines an obsessive adherence to central design principles (the “tight” part) with accommodations to the needs, resources, constraints, and particularities that occur in any school or district (the “loose” part), but only where these do not conflict with the theory of action of the intervention.

How?

Some reforms are too loose (e.g., the ‘Effective schools’ movement)

Others are too tight (e.g., Montessori Schools)

The “tight but loose” formulation

SummaryRaising achievement is important

Raising achievement requires improving teacher quality

Improving teacher quality requires teacher professional development

To be effective, teacher professional development must addressWhat teachers do in the classroomHow teachers change what they do in the classroom

AfL/FA + TLCsA point of (uniquely?) high leverageA “Trojan Horse” into wider issues of pedagogy, psychology, and curriculum
