10 quick lessons from educational thinkers

Praxis, the combination of theory, reflection and practice is precious – as in ‘valuable’ – but it’s not something to be precious or pretentious about. Educational theory is of real use when we reflect on it and apply it in practice. The list below features 10 quick lessons drawn from some of the people featured so far in this blog’s ‘Educational Thinkers’ Hall of Fame’.

Number 10 is specifically about the WEA but has wider application in adult education.

  1. Socrates – Active learning through questioning and discovery leads to deeper understanding of a subject.
  2. Mary Wollstonecraft – Prejudice leads to ill-informed and unfair assumptions about people’s academic potential.
  3. John Dewey – Previous experiences of life and education shape individual students’ personal responses to learning activities.
  4. Benjamin Bloom – Learning can take place at many levels ranging from ‘rote’ learning to active creativity.
  5. Paolo Freire – Education shouldn’t be based on a ‘banking’ system that attempts to deposit knowledge in students’ minds.
  6. Robert Gagne – ‘Teachers have three primary functions: to be a designer, manager and evaluator of learning.’
  7. Jack Mezirow – Transformative education has the potential to set people free from their limitations.
  8. Carol Dweck – The language we use as educators can reinforce the development of ‘fixed mindsets’ or ‘growth mindsets’
  9. John Hattie – Teacher credibility is important in promoting ‘visible learning’ through feedback about students’ progress.
  10. R H Tawney – The purpose of the association [the WEA] is to provide for men and women who want to take their bearings on the world, opportunities of co-operative study, in congenial company, with a leader who knows enough of his (or her) business to be not only a leader but a fellow student.

This blog complements others that I follow, including Pete Caldwell’s at wp.me/p1ynaa-a1 and several others. I’ll list a few in the next blog.

What snippets would you have chosen from any of these or other thinkers to inform practice in adult education?

Educational Thinkers’ Hall of Fame – John Hattie

I’m including John Hattie in the Educational Thinkers’ Hall of Fame because of his reputation for research into positive influences on students’ learning. He was already a well-known academic when he made an international impact with his 2009 book, ‘Visible Learning: A Synthesis of Over 800 Meta-Analyses Relating to Achievement’.

Hattie Visible Learning

Visible Learning – 15 years of research
He based this book on the biggest ever collection of evidence-based research into the most important influences on school-aged students’ achievements. He considered many factors. These included the influence of home, school, curricula, teachers and teaching strategies. His findings are relevant to adult education too.

He analysed all the evidence that he had collected and ranked the various factors in order of their ‘effect-sizes’. Some of his variables, such as ‘feedback’ or ‘acceleration’ can mean different things to different people and Hattie explained them more fully in his narrative.

Hattie’s average effect-sizes
He used the following descriptions to explain ‘effect-size’ as used in the table below:
• An effect-size of 0.5 is equivalent to a one grade leap at GCSE
• An effect-size of 1.0 is equivalent to a two grade leap at GCSE
• ‘No. of effects’ is the number of well-designed studies producing effect-sizes that were averaged in the table’s right hand column.
• An effect-size above 0.4 is significant and above average for educational research.

This extract from a table of his findings shows some of the highest scoring factors that Hattie identified, ranked by their average effect-sizes. Some of his results seem to be highly significant given his explanation that a score greater than 0.5 can raise students’ GCSE grades. His analysis identifies feedback as being massively influential.

Hattie’s conclusions
Hattie is careful not to use his research to produce superficial ‘how to’ guides for teachers but he outlined some signposts to excellence in education in the last chapter of ‘Visible Learning’.

He came to important conclusions about the power of teachers and feedback, developing a model of teaching, learning and understanding based on his ideas of ‘visible teaching and visible learning’. He concluded that we need teachers who are empowered by being educated about how learning is best achieved and who are enthused about their position and responsibility in helping students to achieve as much as possible. He proposed that the best teachers have a powerful sense of personal agency and a belief in their ability to intervene and to make learning happen.

More recent work
Hattie continues to update his research and findings. He has written a follow-up book, ‘Visible Learning for Teachers: Maximizing Impact on Learning’ and, in December 2011, he published an updated version of rankings in his table of classroom interventions based on 141 more meta-analyses, adding 14 more variables to his new list.

The highest new entry of high-scoring influences, in fourth place, was ‘teacher credibility’. This factor wasn’t listed in his original study.

“The key is the students’ perception that teachers have credibility in enhancing their learning,” he said. “Students are very perceptive about knowing which teachers can make a difference to their learning. And teachers who command this credibility are most likely to make the difference.”

“The effects on achievement are high and the reason is that teachers who constantly show students they care, and know about the difference and impact they are having on them, are ‘visible’ and welcomed.”

About John Hattie
johnhattieJohn Hattie is a Professor of Education and Director of the Melbourne Education Research Institute at the University of Melbourne, Australia and was until recently a Professor of Education at the University of Auckland in New Zealand. This is a very brief and basic introduction to his work, which is current and developing.

A feature in the Times Educational Supplement on 23 September, 2012 (http://bit.ly/R47OJj} described Hattie as, “one of the most divisive figures in world education.” It went on to say that, “Opinion is split between those who know of the New Zealander and praise him as the author of teaching’s “holy grail”, and those who know of him and accuse him of being an “egotistical, self-serving” academic, too keen to bask in the limelight.” Strong stuff!

Some readers might have met John Hattie, heard him speak or been influenced by his work. Please feel free to add any further information or links to more resources – or to add your thoughts on the impact and usefulness of Hattie’s research in improving teaching, learning and assessment.
