Sound advice

Tim Neumann getting angry with the mic

Tim Neumann has a reputation for taking (amongst many things) ‘sound’ very seriously. On Zoom he has the most impressive mic, for example. I was keen to get him in to the studio we set up to tap him up about all the settings on the Rodecaster Pro we bought. We decided to switch on the system while we chatted even though I was a bit throaty and the expert set about schooling this amateur in a bunch of things about sound related to settings that are adjustable on the podcasting system we have. In here you can hear about: Compression, pumping, phantom power, de-esser, dynamic volume regulation, high pass filter, noise gate, aural exciter, big bottom and flutter echo.

Learning theory and dietetics

Learning theory and dietetics

This resource has been created as pre-reading for a session I have been invited to lead with students on the MSc Dietetics at UCL. It is my attempt at answering the question: ‘Is there any point in dieticians knowing about learning theory? (professionally I mean, given that it is, of course, inherently interesting!)

People with research or professional interests in educational psychology or teaching understandably and logically have an interest in learning theory. Whether theory provides a template for design of approaches to teaching, learning and assessment or offers an analytical lens to better understand what is happening at an individual or collective level, it makes sense that we challenge our assumptions, experiences and reflections through such theoretical lenses. But what of those whose relationship with teaching or with everyday human tendencies and behaviours is only a tangential part of their role? In any role where one person gives information to others, helps them to understand things or is responsible for changing (or helping to change) behaviours then understanding a little of how people learn will be beneficial. From my (lay) perspective, I imagine that common challenges in dietetics will be interpreting and conveying complex scientific information about nutrition and health and helping people to understand impacts and causation in relation to excess or absence in diet. Consideration of these challenges and issues that arise can be informed through theoretical lenses.

The learning theory landscape

A wordcloud of all the key words for this topic: theory, dietetics, constructivism, social, nutrition, behaviourism, health, diet, psychology are the largestOne of the problems with this is that a quick search for ‘theories of learning’ will present a dazzling, complex, sometimes-contradictory array of theories and ideas. It immediately raises several questions:

  1. Where do you start?
  2. How deep need you go?
  3. How can exposure to learning theory be applied in a meaningful way in context?

The answer to the first question may be ‘right here!’ if you have not studied learning theory before. The second question probably has the same answer as to the question: ‘How long is a piece of string?’ and will inevitably be determined by academic, research and professional roles and interests. The third question is one that we will try to get to grips with here and in the forthcoming session.

Like any other academic field, learning theory has its groupings and areas. The landscape isn’t always represented the same way: you will sometimes see theorists in one category, then another, which can be confusing. This may be due to classification differences, or because the theorist has developed their position over time. To complicate things further, the term ‘theory’ is used to cover a variety of models, approaches and techniques, and often defined by different people in different ways. That said, complication need not be a problem: rather than seeking firmly defined boundaries, think more in terms of spectra and Venn diagrams, where things overlap and interconnect. A main use of theory is to shed light on our experience and help us reflect on – and even change – our practice.


The following theories are both broad and narrow and some can be seen as subsets or informed by wider/ earlier theories. Whether broad or narrow, generalised or specific they have been selected because I think they may be of use to those in the field of dietetics. However, you have more expertise than I do here so it is important your critical eye is focussed and alert. Remember, it is unlikely that you will read a theory, decide ‘ah ha! That’s me from now on’. Rather, you may read, think, reflect, apply and draw on a range of complementary (or contradictory) ideas and approaches as you develop techniques in your future roles as well as using theoretical lenses to better understand what has worked and what has not.

Broad theoretical ‘schools’

Behaviourist theories of learning see the learner as passive; they can be trained using reward and punishment to ‘condition’ them to behave in particular ways (famous theorists in this domain include Pavlov and Skinner whose reach extends into popular understandings unlike most other domains of theory). Learning is seen as a change in behaviour. In health education the role of the expert might be to provide incentives or find ways to disincentivise certain behaviours. Consider the cost of tobacco products and the gruesome images on the packaging. What is the thinking behind this? Can the cost and images be credited with the continuing fall in numbers of smokers?

Cognitivist theories of learning see the learner as actively processing information rather than just being ‘conditioned’ by various stimuli. Cognitivists are concerned with how learners process and remember information, and often test recall as a measure of learning. In health education the expert’s role is to convey information in ways that optimises recall and completeness. Consider the 5 portions of fruit/ veg a day campaign: Whilst there were certainly ‘rewards’ built into the design of the programmes (i.e. health benefits of eating 5 a day) there was also an emphasis on providing and reinforcing information about nutrition and vitamins through attractive materials, booklets, leaflets, connections of school curricula and so on.

Constructivist theories of learning see the learner as an active participant in their own learning. The process of learning is not merely putting knowledge into an empty container. The ‘teacher’ presents knowledge, scenarios, resources, options and problems (or they gain it in another way) and in learning it students ‘construct’ the knowledge for themselves, linking it to what they already know. A variant of this is ‘social constructivism’, which holds that students’ construction of their knowledge is done with others. How might a dietician apply a constructivist approach when working with a client with type 2 diabetes who, by their own admission and despite worsening symptoms, persists in keeping a diet that is sugar, starch and salt rich?

Stop and think

Which broad theoretical approach can you see here?

At my local dentist surgery there is a display case with different sugary snacks, foods and drinks set out very neatly adjacent to piles of sugar equivalent to the actual amount in those foodstuffs. Each has a typed label (like in a museum) with the amount of sugar in grams. There are also a couple of low sugar items. There are no explicit warnings of the dangers of sugar to teeth.


Specific theories: How relevant / useful are these?

Situated Learning theory holds that relevance/ needs of learning are always embedded within a context and culture, so it’s best to teach particular materials within a relevant context – e.g. teaching clinical skills in a clinical setting. Within that context, students learn by becoming involved in a ‘community of practice’ – a group of practitioners – and through ‘Legitimate Peripheral Participation’ move from the periphery of this community towards its centre (i.e. the more expert and involved in practice they become, the closer they move toward the centre). (key names: Vygotsky, Lave)

Social Learning Theory views observation as key to learning; it holds that we learn through observing others, not just what they do but also the consequences of that. People learn from watching older or more expert people. An educator has a role in getting their attention, helping them remember and motivating them to demonstrate their learning. Behaviour is also affected by what they see being rewarded or punished. (key name: Bandura)

Mindset (motivational) Theory argues that if people believe that their ability to achieve something is fixed they have little chance of changing it and they therefore have a fixed mindset. To develop (i.e. learn), a growth mindset is needed and this is related to intrinsic self-belief. The educator’s role is to show belief, exemplify positive behaviours (e.g. hard work and effort should be valued not only results) and showing how to embrace ‘failure’ (key name: Dweck)

Critical Pedagogy is more of a movement than a theory: it holds that teaching cannot be separated from wider social and political concerns, and that educators should empower their ‘students’ to be active, critical citizens. Critical pedagogy is concerned with, whatever the subject, asking students to question hierarchies and power relations and to achieve a higher political consciousness. Paulo Freire, author of Pedagogy of the Oppressed (one of the first books of critical pedagogy) coined the ‘banking model’ in his critique of how some teaching aims to ‘fill’ students up with knowledge as though they are blank slates, merely receiving and storing knowledge. In addition, bell hooks’ work on intersectionality (complex layers of discrimination and privilege according to factors such as race, class, gender, sexuality and disability) might also lend a powerful lens to understand and challenge the nature and role of diet amongst groups as well as in individuals.

Teaching metaphors

a swiss army knife with a brown case and each blade safely tucked in the closed positionI used a number of visual hooks today in a session…it’s actually running right now (they’re in a breakout discussion)… and I asked what this swiss army knife might represent in the context of the short course they are on. One of my amazing colleagues (Most are PhD students/ PGTAs), Elizabeth, said:

The swiss-army knife: establishing an arsenal of multiple tools for teaching and for reflection, to allow for flexibility and adaptability as an educator–in the short term (in class, adapting to students), and in the long term (throughout a course, throughout a career)

I was very impressed as it articulated an idea that was, at best, only half-formed in my own mind so I thought I’d share it here!


Digital accessibility and you: Where are you now and where could you be?

This post accompanies a workshop led by Ben Watson (Head of Digital Accessibility at UCL (University College London) and Martin Compton (UCL Arena). In it are resources we will be using in the session.  But please do read and try the linked activities for yourself even if you are not attending! The session is designed to raise awareness of what digital accessibility means and what a UCL approach to digital accessibility requires us to know and to do. The workshop is also an opportunity for us to pilot aspects of an (in-development) Accessibility Engagement Tool. The tool is being designed to help colleagues discuss their accessibility engagement and get clear direction on what they can do to further improve the accessibility of their teaching. The goal is to enable colleagues to set some clear digital accessibility goals irrespective of their starting point.

Accessibility in its broadest sense is about making activities, environments, and information as useable and meaningful as possible in ways that do not exclude people. It is about empowerment, about minimising frustration and about effective anticipatory design. Digital accessibility therefore ‘provides ramps and lifts into information.’ It includes ensuring that all information we create at UCL can be seamlessly consumed by everyone that wishes to access it. As UCL’s digital accessibility policy is rolled out, we hope that we can help demystify aspects of digital accessibility

The accessibility engagement model and accompanying self-assessment tool are being designed to enable colleagues to plot their own level according to a series of questions about aspects of digital accessibility. The idea will be that through series of questions related to:

  1. Values and beliefs
  2. Knowledge and skills
  3. Actions and behaviours

…the tool will plot an overall position as well as noting areas of developmental or resourcing need. As we have shaped this model one area that has led to much discussion, consultation and head scratching are the labels we are appending to levels. As a starting point we propose six levels of ‘maturity status’ and invite colleagues to decide which level they are currently at:

Accessibility Engagement Model

Level Accessibility Maturity Status Characteristics and indicative practices
0 Unwilling Context means that this is not prioritised in current working environment given competing commitments and pressures.

Time is a key point of resistance.

1 Unable Don’t know where to start and/or in need of direction, support, and prioritisation.
2 Reluctant compliant Awareness of accessibility principles and drivers; only adopting bare minimum when encouraged.
3 Willing compliant Awareness of accessibility design principles; willingly adopting good basic level of accessibility.
4 Ally Connected to wider pedagogical values; allies are vocal on behalf of students. Role model or provide case studies/ templates for others in their departments.
5 Champion and Co-creator Activists/ innovators who work with students to understand and design more accessible approaches and resources. Potential contributors to institutional policy and strategy.

Digital accessibility behaviours

Whilst the questions and tool are still under construction, for now we invite colleagues to use the Mentimeter linked below to respond briefly to some ‘actions / behaviours’ statements.

Please access the Mentimeter so that you can (anonymously) assess your behaviours against a number of statements. For each statement you are able to choose from 0-5 as follows

0. Not on my radar

1. Would if I knew how

2. Rarely or if required

3. Sometimes

4. Always

5. Yes! And support others

The cumulative results (i.e. all those who respond) can be seen in the presentation slides which display results.

The statements in the slides can also be seen below.

  1. I use descriptive hyperlinks rather than ‘click here’ or unconcealed links
  2. I ensure that visual materials are conveyed effectively to those who cannot see them using alternative text descriptions and audio descriptions
  3. I ensure my documents are navigable with a structured set of headings
  4. I ensure tables are easy to read and have clear heading rows
  5. I enable automatic speech recognition captions in all multimedia
  6. I enable automatic speech recognition captions in all multimedia and make corrections to them
  7. I offer a range of formats for my materials e.g., PDF, html and docx
  8. I signpost students to assistive technologies so that they can have more support accessing materials
  9. I share electronic content with students (such as slides) ahead of teaching sessions
  10. I accessibility check my documents before finalising them
  11. I explain acronyms when I use them
  12. I check my work for colour contrast issues
