8. We believe “engaging in learning
activities…transfers the content of the activity to
the mind of the student…”
But “as learning occurs, so does forgetting…”
“learning takes time and is not
encapsulated in the visible here-and-now
of classroom activities.”
Graham Nuthall (2005)
The input/output myth
9. The myth of progress
What we think
progress looks like
12. Learning vs performance
• We can only infer learning from
performance
• Performance is a very poor indicator of
learning
• Reducing performance might actually
increase learning
13. ‘Poor proxies’ for learning
• Students are busy: lots of work is done
(especially written work)
• Students are engaged, interested, motivated
• Students are getting attention: feedback,
explanations
• Classroom is ordered, calm, under control
• Curriculum has been ‘covered’ (i.e. presented
to students in some form)
• (At least some) students have supplied correct
answers (whether or not they really understood
them or could reproduce them independently)
Robert Coe, Improving Education: a triumph of hope over
experience
14. So where does that leave us?
• Is lesson observation wrong?
15. The MET Project
• If a lesson is given a top grade, there’s
a 78% chance a second observer will
give a different grade
• If a lesson is given a bottom grade,
there’s a 90% chance a second
observer will give a different grade.

16. Do we know a successful
teacher when we see one?
• Fewer than 1% of lessons judged
inadequate are genuinely inadequate
• Only 4% of lessons judged outstanding
actually produce outstanding learning
gains
• Overall, 63% of judgements will be wrong

Teacher Education, 62(4), 367–382.
17. So where does that leave us?
• Is lesson observation wrong?
• What about AfL?
• Outstanding teaching?
• Marking & feedback?
18. What can we do?
• Increasing retrieval strength only
improves performance
• Increasing storage strength depends
on the power of forgetting:

test results?

28. Feedback: What Hattie
actually says
Feedback is one of the most powerful
influences on learning and
achievement, but this impact can be either
positive or negative.
Simply providing more feedback is not the
answer, because it is necessary to consider
the nature of the feedback, the timing,
and how the student ‘receives’ this
feedback (or, better, actively seeks the
feedback) The Power of Feedback (2007)
29. With inefficient learners, it is better for a
teacher to provide elaborations through
instruction than to provide feedback on
poorly understood concepts…
Feedback can only build on something;
it is of little use when there is no initial
learning or surface information.

Feedback: What Hattie
actually says
30. The power of feedback
Response type
Feedback indicates performance…
exceeds goal falls short of goal
Change
behaviour
Exert less effort Increase effort
Change goal Increase aspiration Reduce aspiration
Abandon goal Decide goal is too
easy
Decide goal is too hard
Reject feedback Feedback is ignored Feedback is ignored
Dylan Wiliam
31. Bjork on feedback
• Empirical evidence suggests that delaying,
reducing, and summarizing feedback can
be better for long-term learning than
providing immediate, trial-by-trial feedback.
• Numerous studies—some of them dating
back decades—have shown that frequent
and immediate feedback can, contrary to
intuition, degrade learning.
Learning vs Performance (2013)
32. But, why?
• Immediate feedback can prevent
memorisation
• Students can become dependent
• Slows down pace of learning
• Providing feedback of success is a waste
of effort (opportunity cost)
33. What should we do?
• Separate learning from performance
• Introduce desirable difficulties
• Question your assumptions – be
prepared to ‘murder your darlings’.
