Maturity and the case of graded lesson observations - can the FE sector handle the truth!

Last Friday saw the TES publish an article on graded lesson observations within the further education sector where Lorna Fitzjohn, OfSTED's national director for learning and skills stated : “The big question that we’ve had from some leaders in the sector is: is the sector mature enough at this point in time not to have us (OfSTED) grading lesson observations?”  In responding to this statement it seems sensible to ask the following questions:
  1. What does the research evidence imply about the validity and reliability of graded lesson observations?
  2. What is the best evidence-based advice on the use of graded lesson of observations?
  3. What do the answers to the first two questions imply for the maturity of the leadership and management of the further education sector?
What does the research evidence imply about the validity reliability of lesson observations?
      O’Leary (2014) undertook the largest ever study into lesson observation in the English education system and investigated the impact of lesson observations on lecturers working in the FE sector. Lecturers' views when asked about graded lesson observations were summarised as :
Over four fifths (85.2%) disagreed that graded observations were the most effective method of assessing staff competence and performance. A similarly high level of disagreement was recorded in response to whether they were regarded as a reliable indicator of staff performance. However, the highest level of disagreement (over 88%) of all the questions in this section was the response to whether graded observations were considered the fairest way of assessing the competence and performance of staff. 
     Not only are there 'qualitiative' doubts about the reliability and validity of lesson observations, there are also 'quantitative' based objections to their use, particularly when un-trained observers are used. Strong (2011) et al found that the correlation coefficient for untrained observers agreeing on a lesson observation grade was 0.24 which runs counter to sector leaders advice to  both Principals and Governors to 'trust your instincts.'
     Furthermore, Waldegrave and Simons (2014) cite Coe’s synthesis of a number of research studies, which raises serious questions about the validity and reliability of lesson observation grades. When considering value added progress made by students and a lesson observation grade (validity) , Coe states that in the best case there will be only 49% agreement between the two grades and in the worst case there will be only 37% agreement. As for the reliability of grades Coe’s synthesis suggests that in the best case there will be 61% agreement and in the worst care only 45% agreement between two observers.
      The above would suggest graded lesson observations provide an extremely shaky foundation on which to make judgements about the quality of teaching and learning within the further education sector.   It is now appropriate to turn to the current best evidence-based advice on the use of graded lesson observations.

So what is the best evidence-based advice on the use of lesson observations?
     Earlier this year at the Durham University Leadership Conference Rob Coe stated that the evidence suggests
Judgements from lesson observation may be used for low-stakes interpretations (eg to advise on areas for improvement) if at least two observers independently observe a total of at least six lessons, provided those observers have been trained and quality assured by a rigorous process (2-3 days training & exam). High-stakes inference (eg Ofsted grading, competence) should not be based on lesson observation alone, no matter how it is done
      In other words, the current practice of a graded lesson observation system based on one or two observations per year - which is the case in the vast majority of colleges - is not going to provide sufficient evidence for low stakes improvement never mind high stake lecturer evaluation.  That does not mean lesson observations should not take place but as Coe suggests they need to take place alongside reviews of other evidence : such as student feedback, peer-review and student achievement.
  
So what does the above mean for the leadership and management of the further education sector?
     First, there would appear to be a clear research-user gap, with sector leaders giving out advice which is inconsistent with the best available evidence. Second, if leaders and managers within the sector have to rely upon graded lesson observations to attempt to demonstrate and track improvement of teaching and learning, then the sector needs to begin to develop a wider and more sophisticated range of processes and measures to judge the quality of teaching and learning. Third, the reliance on graded lesson observation suggests a prevailing leadership and management culture which is founded on an assumption that to improve performance requires the removal of poor performers.  For me, Mark Tucker (2013) sums up the way forward

There is a role for teacher evaluation in a sound teacher quality management system, but it is a modest role. The drivers are clear: create a first rate pool from which to select teachers by making teaching a very attractive professional career choice, provide future teachers the kind and quality of education and training we provide our high status professionals, provide teachers a workplace that looks a lot more like a professional practice than the old-style Ford factory, reward our teachers for engaging in the disciplined improvement of their practice for their entire professional careers, and provide the support and trust they will then deserve every step of the way.

And if we take that as the definition of a mature system, then maybe FE has a long way to go.

Research Leads Conference and Evidence-Based Practice - How to avoid re-inventing the wheel

On Saturday I had the privilege of attending ResearchED's Research Leads one-day conference.  It was an incredible day full of intellectual challenge mixed with the opportunity to meet some wonderful colleagues.  However, what was deeply ironic given that the event was being held in the Franklin Wilkins building at Kings' College London, and which is named after two of the discoverers of the 'double-helix', was that we were not standing on the 'shoulders of giants'.  Many of the issues and topics which we wrestled with have already, to a very large extent, been engaged with by practitioners in the fields of evidence-based medicine and more generically evidence-based practice.
     So how do we go about standing on the shoulders of giants, particularly with reference to the role of a research-lead in a school and how research-leads could go about performing their task.  Both Alex Quigley and Carl Hendrick did an admirable job in trying to map out the territory for the research-lead and some of the roles and tasks that need to be performed.  For me a fantastic starting point for building upon this discussion is the work of Barends, Rousseau, & Briner's (2014) and their pamphlet on the basic principles of evidence-based management.  Barends* et al state:


From the point of view of a school-research lead this definition has a number of implications.
  1. Being a research-lead involves more than just 'academic' research, it involves drawing upon a wider range of evidence - including both individual school data and the views of stakeholders, such as staff, pupils, parents and the wider community.
  2. This approach can be largely independent of work with higher education institutions.  It is not necessary to partner with a HEI to be an evidence-based practitioner or evidence-based school. It might help, specifically when supporting staff develop as evidence-based practitioner but it's not absolutely necessary.
  3. At the heart of this process is being able to translate school issues or challenges into a well formulated and answerable problem and evidence-based medicine has a number of tools which can help with this process.
      So what does this mean for the research lead's role in a school? Well a highly relevant place to start is to look at those leadership capabilities which appear to have the biggest impact on student and in this case teacher learning.    Given that we a seeking to develop processes which are 'research' led there is no better place to start than the work of Viviane Robinson on Student-Centred Leadership, which is based on both a best-evidence synthesis of the impact of leadership on student achievement, and which identifies three key leadership capabilities: applying relevant knowledge; solving complex problems and building relational trust.  Below I have begun to  tentatively examine what this might mean for research leads, so here goes:
  • Applying relevant knowledge - this about using knowledge about effective research in order to help colleagues become better practitioners, for example, helping to ask well-formulated and answerable questions.
  • Solving complex problems - research is a tricky and slippery topic and it's about discerning the specific research challenges faced by a school and then crafting research processes in order to address those challenges.
  • Building relational trust - which is an absolute pre-requisite for such work.  Research leads need to gain the trust of colleagues, otherwise it will be virtually impossible to develop a research agenda in schools.  And in undertaking this role, this require a specific set of skills which will allow both the research lead and practitioner to engage in effective evidence-based practice.
In order to help with the development of the role of the research-leads the next few posts in this series will draw upon material from both the evidence-based medicine and the broader field of evidence-based practice to look at the following:
  • How to get better at asking well-formulated questions.
  • How to write a short-paper on a Critically Appraised Topic
  • Some of the current challenges faced by evidence-based practitioners, particularly in the field of medicine.

Dangerous Half Truths and Total Nonsense - Evidence Based Practice and two avoidable mistakes

A few weeks ago I wrote about how difficult it is to learn from others using casual benchmarking and the implications this had for leadership teams who followed the Skills Commissioners advice to visit other colleges.  In this post I continue to draw upon the work of Jeffrey Pfeffer and Robert I Sutton and their 2006 book Hard Facts Dangerous Half-Truths and Total Nonsense : Profiting from evidence-based management  and some of the practices which are confused with evidence based management. In addition to casual benchmarking Pfeffer and Sutton identify two other practices - ,  doing what seems to have worked in the past and following deeply held yet unexamined ideologies -  which can lead to both to poor decisions and detrimental outcomes for college stakeholders i.e. staff, students, parents, employers and the community.   These two practices are now explored in more detail.

Doing what seems to have worked in the past
     As colleagues move one from role to another, be it within a school or college the temptation is use that experience and apply it to a new setting.  Pfeffer and Sutton argue that problems arise when the new situation is different from the past and when what we have learned worked in the past, may have actually have been wrong.  There is a huge temptation to import management practices and ideas from one setting to another without sufficient thought about context, either old or new.   Pfeffer and Sutton identify three simple questions that can assist in avoiding negative outcomes arising from inappropriately repeating past strategies and innovations.
  • Is the practice that I am trying to import into a new setting, say lesson planning, peer tutoring, e-learning, pastoral arrangements or information and guidance arrangements directly linked with previous success.   Was the success which is now being attempted to be replicated despite of the innovation which was adopted rather than because of it?
  • Is the new - department, school, college or other setting - so similar to past situations that what worked in the past will work in the new setting?  For example, getting the balance right between delegation and control may be different between an outstanding school/college and one that is on a journey of improvement.
  • Why was past practice  say graded lesson observations - effective, what was the mechanism or theory which explains the impact of your previous actions.  If you don't know what was the theory or mechanism that underpinned past success then it will be difficult to know what will work this time.  (Adapted from Pfeffer and Sutton p9)
Following deeply held yet unexamined ideologies 
     The third basis for flawed decisions-making is deeply held beliefs or biases which may cause school and college leaders to adopt particular practices, even though there maybe little or no evidence to support the introduction of the proposed practice or innovation. Pfeffer and Sutton suggest a final three questions to address this issue.
  • Is my preference for a particularly leadership style or practice because it fits in with my belief about people -  for example, do I support the introduction of PRP for teachers because of my belief of the motivational benefits of higher salaries and payment for results?
  • Do I require the same level of evidence or supporting data, if the issue at hand is something that I am already convinced what the answer is?
  • Am I  allowing my preferences to reduce my willingness to obtain and examine data and evidence which may be relevant to the decisions.  Do I tend to read the educational bloggers/tweeters who agree with me or do I search out views that are in contrast to my own.  Am I willing to look at research which challenges my preconceptions for example Burgess et al (2013) and the small but positive effect of league tables.(Adapted from Pfeffer and Sutton, p 12)
To conclude :
     If an evidence based approach is taken seriously it could potentially change the way in which every school/college leader thinks about educational leadership and management, and subsequently change the way the behave as school/college leader.  As Pfeffer and Sutton state:
     First and foremost, (evidence based management) it is way of seeing the world and thinking about the craft of management.  Evidence-based management proceeds from the premise that using better, deeper logic and employing facts to the extent possible permits leaders to do their jobs better. Evidence based management is based on the belief that facing the hard facts about what works and what doesn't, understanding dangerous half-truths that constitute as much conventional wisdom about management, and rejecting the total nonsense that too often passes for sound advice will help organizations perform better (p13)

What Works? Evidence for decision-makers - it's not quite that simple.

This week saw the publication of the What Works Network's What Works? Evidence for Decision-Makers report which in the context of education identified a number of practices, for example, peer tutoring and small-group tutoring which appear to work.  On the other hand, the report also identified a number of practices which appeared not to work, for example, giving pupils financial incentives to pass GCSE or pupils repeating a year.  However, whenever such  reports come out which identify supposedly what works there can be tendency to confuse 'evidence' with evidence-based practice.  In particular, there is a danger that published research evidence is used to reduce the exercise of professional judgment by practitioners.  Indeed, one of the great myths associated with evidence-based practice is that it is the same as research determined or driven practice.  As such, it is potentially useful for educationalists interested in evidence-based education to gain a far greater understanding of what is meant by evidence-based practice.
      Barends, Rousseau, & Briner's (2014) recent pamphlet on the basic principles of evidence-based management  define evidence based practice as the making of decisions through the conscientious, explicit and judicious use of the best available evidence from multiple sources by:
  • Asking: translating a practical issue or problem into an answerable question
  • Acquiring: systematically searching for and retrieving the evidence
  • Appraising: critically judging the trustworthiness and relevance of the evidence
  • Aggregating: weighing and pulling together the evidence
  • Applying: incorporating the evidence into the decision-making process
  • Assessing: evaluating the outcome of the decision taken
to increase the likelihood of a favourable outcome (p2)*.
In undertaking this task information and evidence is sought from four sources
  1. Scientific evidence Findings from published scientific research.
  2. Organisational evidence Data, facts and figures gathered from the organisation.
  3. Experiential evidence The professional experience and judgment of practitioners.
  4. Stakeholder evidence The values and concerns of people who may be affected by the decision.
In other words, evidence based practice involves multiple sources of evidence and the exercise of sound judgement.
     Furthermore, drawing upon Dewey's practical epistemology Biesta argues that the role of research is to provide us with insight as to what worked in the past, rather than what intervention will work in the future.  As such, all that evidence can do is provide with us a framework for more intelligent problem-solving.  In other words, evidence cannot give you the answer on how to proceed in any particular situation, rather it can enhance the processes associated with deliberative problem-solving and decision-making.
     So what are the key messages which emerge from this discussion.  For me at least there would be appear to be four key points

  • Research evidence is not the only fruit - in other words when engaging in evidence based-practice research evidence is just one of multiple sources of evidence.
  • Even where there is good research evidence, that does not replace the role of judgment in making decisions about how to proceed.
  • All that research evidence can do is tell you what worked in the past, it can't tell you what will work in your setting or in the same setting at some time in the future.
  • Research evidence provides a starting point for intelligent problem-solving

How past experience can get in the way of good teaching and learning.

This post has been inspired by Oliver Burkeman's recent column  ' Don't get caught in the monkey trap'.  In this column, Burkeman refers to the Einstellung effect, and how previous experience can lead us to being 'blind' to new and better ways of doing things.  Bilalic, McLeod and Gobet demonstrate how experts once they have found a way to proceed, may find this prevents a better option from being identified.  This process may lead to a wide-range of cognitive biases - both in experts and the less expert - such as confirmation bias whereby there is a tendency to ignore evidence which does not fit with current preconceptions.

So what are the implications of the Einstellung effect for teachers and those who lead educational institutions.  Well for me there would be appear to be several.
  • Experienced teaching professionals should constantly challenge themselves by acknowledging that previous experience does not always provide the best answer to any given situation.
  • Leaders within schools and colleges, who are likely to be some of the most experienced colleagues within a school and college, should lead by example and show the necessity for CPD which specifically challenge previously held assumptions and experiences.
  • Recruitment processes for new positions may overly value experienced candidates over less experience candidates.
  • The perceptions and viewpoints of less experienced members of staff are as valuable as more senior staffroom 'sages'.
  • Tasks or project groups should include a wide range of participants, with differing types of experiences.
  • Colleagues should constantly seek  to be placed in new, uncomfortable though 'safe' situations to allow for the development of a greater repertoire of teaching, learning and management  strategies.
And the implications for educational bloggers and tweeters?  Many of the posts/tweets within the blogosphere/twittersphere argue for experienced teaching professionals to be trusted to be able their exercise their judgment.  Unfortunately, the Einstellung effect would suggest that 'trusting' in experience may not necessarily bring about the best outcomes for pupils and learners.  However, and let's make this absolutely clear,  I'm not arguing to reduce levels of trust, but rather that an essential element of gaining, using and maintaining such trust, is to openly acknowledge the weaknesses of our expertise, and demonstrate how we are not only constantly challenging others, but just as importantly constantly challenging ourselves.

Further Cuts in the FE budget and Creating a Learning Society - Does it make any economic sense?

This week has seen concern expressed by the Association of Colleges about the FE sector having to find further budget cuts, with reports that another £48 billion of cuts in public expenditure being planned.  In particular, there are fears that the  FE sector will once again endure more than its' fair share of the cuts, given the past ring-fencing of the schools budget.   However, in this post I will put the forward that a demand for  'fairness' is not the way to win this argument, instead rather 'hard-nosed' economics is what is required.  In making this argument I will drawn upon the implications for the further education sector of Joseph Stiglitz and Bruce Greenwald's new book Creating a Learning Society : A New Approach to Growth.
         In their opening chapter Stiglitz and Greenwald state:
    .... that most of the increases in the standing of living, are as Solow suggests. a result in increases in productivity - learning how to do things better.  And if it is true that productivity is the result of learning and that productivity increases (learning) are endogenous, than a focal point of policy ought to be increasing learning within the economy : that is, increasing the ability and incentives to learn, and learning how to learn, and then closing the knowledge gaps that separate the most productive firms in the economy from the rest.  Therefore creating a learning society should be one of the major objectives of economic policy.  If a learning society is created, a more productive society will emerge and standards of living will increase. (p5).

         Of particular relevance to further education, Stiglitz and Greenwald argue that learning from one firm or sub-sector firm spills over to other firms and sub-sectors within the industrial sector, through labour mobility and changes in the use of technology.  However, knowledge is a public good - with the cost of others benefitting from such knowledge having a zero marginal cost,  Furthermore, it is challenging if not impossible to prevent other firms or individuals gaining from the learning and knowledge which has taken place within a firm.  Stiglitz and Greenwald subsequently demonstrate that markets are neither efficient in the production and dissemination of learning and knowledge.  As a result, if there are spillovers from one firm, sub-sector or industry to another, then there will be underproduction of knowledge and learning.  This occurs because when firms are making decisions about investment in learning capacity and capabilities they will not take into account the benefits accrued by other firms or individuals.

         Furthermore, Stiglitz and Greenwald  recognise the critical importance of cognitive frames in that :Individuals and firms have to adopt a cognitive frame, a mindset which is conducive to learning. That entails the belief change is possible and important - and can be shaped and advance. by deliberative activities. Stiglitz and Greenwald argue such cognitives frames have implications for a number of issues including: whether we learn; being 'stuck' with particular cognitive frames; and, what we learn.

         So what does this mean for the FE sector? My initial thoughts on the matter, would suggest the following. First, from policymakers there needs to be a recognition of the essential role that further education plays in the long-term health of the economy.  Recent reductions in funding for adult education are not consistent with creating the conditions by which a developed economy grows.  Second, an education and training market led by employers is likely to lead to an under-investment in knowledge and learning.   Third, FE colleges have a critical role to play in the local economy in maximising the externalities created by investment in education.  In particular, colleges are incredibly well placed to leverage the spillovers that are generated in local economies through.  These spillovers can be enhanced by ensuring the use of knowledgeable and skilled visiting lecturers who are technical specialists their field or it could be as simple as individual learners sharing their experiences with others.  In doing so, colleges can act as an essential hub of economic growth by making connections between firms and ensuring individuals have access to appropriate education and training.   Finally, individual lecturers have a responsibility to focus on developing learner mindsets which increase learners capacity as life-long learners.

         I hope that I have begun to demonstrate that the compelling argument for no future cuts in expenditure is economic, in that colleges are hub for knowledge and learning bringing about future economic growth.  It's absolutely right to argue for fairness of treatment in relation to schools and universities though in the current political climate we need to be making a compelling and demonstrable economic case for additional investment in further education and training.  I hope this post makes some small contribution to making that case.

    'What Makes Great Teaching' - is it time for a critical re-appraisal

    Over the last two weeks we have seen both the publication of the Sutton Trust's report on "What Makes Great Teaching" and the Sutton Trust/ Gates Foundation international teaching summit held in Washington DC.   Indeed, there have been a number of blog posts from attendees reporting on the summit, for example John Tomsett and Tom Sherrington,  with Mr O'Callaghan providing an invaluable summary of relevant news and blogposts. Given this increased focus and attention on evidence-based education it seems reasonable to pause and reflect, as the notion of evidence-based education is not an uncontested concept.  As one of the key aspects of evidence-based practice is to challenge one's own cognitive biases and look at competing arguments and perspectives, it seemed sensible to me, a self-confessed advocate of evidence-based education, to consider some alternative viewpoints.  In doing so, I will not be arguing for, or against any particular approach to teaching or pedagogy.  Instead, I will be trying to gain a greater understanding of some of the underpinning assumptions  of  'What Makes Great Teaching' so hopefully it can become an even more useful intellectual stimulus for educational research and practice.   Drawing upon the work of Biesta (2007) the rest of this post will cover the following ground:
    • general objections to evidenced based education;
    • the non-causal nature of education;
    • educational research and intelligent problem-solving;
    • distinguishing between the cultural and technical purposes of education;
    • the implications of the above for the dissemination, implementation and follow-up to 'What Makes Great Teaching'.
        Biesta states that opponents of evidence-based education have a raised a number of doubts about the appropriateness of an evidence based approach to educational practice including: one, evidence based education being part of the new public management agenda; two, evidence-based medicine being an inappropriate template for the development of evidence-based education; three, issues around the nature of evidence within the social sciences.   .  
         Biesta goes onto argue that evidence-based education implies a particular model of professional action i.e an effective intervention can bring about the required outcome. Biesta argues that education cannot be understood in terms of cause and effect due to the non-causal nature of educational practice, with the 'why, what and the how' of education being intimately bound together.  As such, an essential component of being an educational practitioner is the exercise of judgment in what is 'educationally desirable'(p21)
        Secondly, drawing upon Dewey's practical epistemology Biesta argues that the role of research is to provide us with insight as to what worked in the past, rather than what intervention will work in the future.  As such, all that evidence can do is provide with us a framework for more intelligent problem-solving.  In other words, evidence cannot give you the answer on how to proceed in any particular situation, rather it can enhance the processes associated with deliberative problem-solving and decision-making.
         Thirdly, Biesta argues that evidence-based education has too great a focus on the technical processes of education - what works or does not work - rather than performing a more nuanced and profound cultural function.  Biesta argues that an open and democratic society should be informed by debate and discussion on the 'aims and ends' of our educational endeavours, whereas evidence-based education is currently too focused on the technical means.  
         So what are the implications of Biesta's stance for our reading of 'What Makes Great Teaching'. One could certainly read the report as sitting very clearly within a technocratic model of education, with the three simple questions which inform the report focusing on the what and how of education, with no consideration of 'why'.  As such, it could be argued that to maximise the benefit 'What Makes Great Teaching' it requires a broader and far more wide ranging discussion into the very purposes of education. Leaders of staff within schools and college's when discussing the implication of 'What Makes Great Teaching'  should do so in a way which facilitate the democratic discussion of the purposes and ends of both education and the school and college.  Reflecting upon how these technical recommendations can be implemented within the school/college in a way which is empowering for both staff and students. 
         A key assumption of 'What Makes Great Teaching' is that educational reality involves clear relationships between cause and effect, with particular approaches to teaching being more effective in bringing about the desired student outcomes.  I'm not going to argue either for or against objectivist or subjectivist stances to epistemology and ontology, others are far better able to do so.  That said, if we are to be evidence-based practitioners it is essential that we fully explore the underpinning assumptions of research, in this case assumptions of cause and effect, with this especially being the case if the research corresponds with existing perspectives.
        As for the practical implications of 'What Makes Great Teaching'  for educational practice, even though the report identifies the components of great teaching, the frameworks which can 'capture it ' and what could be done to develop improved professional learning this does not, or should not provide a set or recipes or check-lists that will guarantee better teacher learning and student/pupil outcomes.   This is certainly the case given the fast-changing world and the implications for pedagogy  and learning of ubiquitous mobile technology (See Benedict Evans' recent presentation).  'What Makes Great Teaching" tells us what may have worked in the past, it may tell us what could work in the future, though not definitively. As such 'What Makes Great Teaching' provides is a valuable resource for practitioners - be it headteachers or teachers - to engage in reflection which will be increase their capacity and capability to find 'solutions' which are fit for their particular settings.
        Finally, if reading 'What Makes Great Teaching' provides a prompt to read other reports and articles which have a different perspective on evidence-based education, so that as a result one has a greater breadth of understanding of the challenges of evidence-based education and the cultural implications, then the report my have provided both a technical and cultural stimulus to ensuring pupils and students experience even greater teaching.
