The Cognitive VO2 Max: From Disney on Ice to Dyslexic Epiphanies in the Print Shop

Hello, everyone. It’s been a week since I last sat down to blog, and I have to start by acknowledging the obvious: the sun is finally shining here in Stoke-on-Trent.

From a purely systemic perspective, it is fascinating how deeply our biology is tethered to our local climate. We’ve had a consecutive spell of consistently warm, sunny weather, and the shift in the collective mood is palpable. As a former Natural Scientist who spent years looking at the exchange of carbon between soil, plants, and the atmosphere, I always view these seasonal shifts through the lens of ecosystems. Just as a peat bog requires specific thermal and hydrological conditions to sequester carbon efficiently, human beings require sufficient solar radiation to synthesize Vitamin D and regulate serotonin. When the weather improves, our internal ecosystems rebalance. Everyone simply feels better.

This week has been a profound lesson in systems, energy, and endurance—both physical and cognitive.

Clocking 22,000 Steps: The Albert Dock and Experiential Learning

We kicked off the weekend with a family trip to Liverpool. We drove up on Friday and stayed at the Hampton by Hilton, a brilliantly located spot just a short walk from the Royal Albert Dock. Liverpool is a city built on movement, trade, and dynamic systems, and we certainly tapped into that energy.

After checking in and grabbing a fantastic pizza at the hotel to refuel, Saturday became an absolute marathon of experiential learning. We hit the World Museum, navigated the bustling shops, and kept moving. By the end of the day, I looked down at my watch and realized I had clocked up an astonishing 22,000 steps.

As a pragmatic SEND teacher, I constantly advocate for learning outside the classroom. The human brain evolved to map environments while moving through them. When my kids are walking through a museum, they aren't just looking at artifacts; their spatial memory, motor planning, and visual processing are all firing simultaneously. It’s a beautiful, messy, highly effective way to absorb the world.

The Skater’s VO2 Max and the Neurodivergent "Cognitive Marathon"

The main catalyst for the Liverpool trip, however, was taking my two daughters to see Disney on Ice. We saw representations of Beauty and the Beast, Rapunzel, Frozen, Moana, Cinderella, and of course, Mickey and Minnie. As a dad, I naturally loved seeing how captivated my girls were. But as a scientist and a teacher, my brain went somewhere entirely different: human performance metrics.

Ice skating is a phenomenally challenging biomechanical feat on its own. Now, add heavy, restrictive, full-body costumes. Then, factor in that these professional athletes are performing three highly dynamic, acrobatic shows a day.

Sitting in the audience, I couldn't help but marvel at their cardiovascular systems. These performers must have an absolutely monstrous VO2 Max—the maximum rate at which the heart, lungs, and muscles can effectively use oxygen during exercise. They are elite aerobic engines disguised as cartoon mice and princesses.

This got me thinking about endurance, which is a concept I lean on heavily in my SEND classroom.

For a neurotypical person, reading a page of text is like a leisurely stroll. But for my dyslexic and dyspraxic students—and indeed, for myself—decoding symbols on a page is a high-intensity sprint. We run a "Cognitive Marathon" every single day. Just as the skaters rely on their VO2 Max to sustain physical exertion, neurodivergent individuals rely on their "Cognitive VO2 Max" to process information.

John Sweller’s Cognitive Load Theory beautifully illustrates this. When a student with a specific learning difficulty tries to read, the extraneous load (the effort required to simply decode the letters) completely overwhelms their working memory. By the time they figure out what the words say, they have zero cognitive energy left to understand what the words mean. I know this frustration intimately; fatigue exacerbates my own dyslexia, leading to mixed-up words or reading entire pages while absorbing absolutely nothing.

Hacking the Bottleneck: World Book Day and Audio Epiphanies

This brings me to World Book Day tomorrow. While reviewing the speech-to-text draft of this very blog post, I had to laugh—my dictation software hilariously translated my upcoming wardrobe plans into "Wild book day T shits." A classic piece of assistive tech irony for a dyspraxic teacher!

But the message on the t-shirt I’ve created for tomorrow is deeply serious, and it stems from a profound lightbulb moment I had years ago.

I was out in the garden, digging in the soil, listening to an audiobook. Suddenly, the realization hit me: I was absorbing complex information, visualizing scenarios, and retaining data effortlessly. Why? Because I had bypassed the decoding bottleneck.

My t-shirt tomorrow carries a simple, pragmatic message: If you have a neurodiversity barrier to reading, do not let it stop you. You can always enjoy and conquer books through audio. According to the British Dyslexia Association, around 10% of the UK population is dyslexic. If we force those individuals to rely solely on visual decoding, we are artificially restricting their intellectual potential. Using text-to-speech or audiobooks isn't "cheating"; it is a systemic hack. It is the equivalent of giving a scientist an electron microscope instead of a magnifying glass. By removing the friction of decoding, we free up the brain's processing power for critical thinking, imagination, and comprehension.

Resilience in the Print Shop Ecosystem

Back at college this week, endurance was required in a different format. We’ve been hit by a wave of staff sickness, a reality that every teacher knows well. Channeling a bit of Ernest Shackleton’s leadership ethos, I gave up my Planning, Preparation, and Assessment (PPA) time to step in and keep the ship moving forward.

We focused heavily on the vocational Print Shop, which I view as a micro-economy within the college. According to the Office for National Statistics (ONS), the employment rate for autistic adults and those with severe learning disabilities remains unacceptably low—often hovering around the 22% mark.

Vocational education is our strongest lever to change that statistic.

We got to work improving the aesthetics of the shop. We redesigned the window displays and put up infographics that clearly showcase the professional skills our learners are developing. We also kicked off a major order of merchandise for the Canal & River Trust, using vinyl presses to create a highly professional finish.

When neurodivergent learners are placed in a hands-on, practical environment, magic happens. We bypass the traditional academic barriers and tap straight into their kinetic intelligence and problem-solving abilities. Working on real-world orders for real-world organizations like the Canal & River Trust instills a sense of pride and industrial rigor that you simply cannot replicate with a worksheet.

Looking Forward: AI, Peer Exchange, and the Chaos of Life

As I look ahead to the next month, my calendar is an intricate tapestry of professional duties and personal chaos. On the home front, we have hit the age where school friends are suddenly having birthday parties every weekend; I think we have three to attend in the next four weeks alone!

Professionally, I am gearing up for our Peer Exchange week. I’ve put my name down to deliver a session on the integration of Artificial Intelligence in education. I am a massive advocate for using AI to hack the administrative barriers of teaching. I’ll be showing staff how to use AI to streamline lesson planning, track student progress, and manage assessments.

Crucially, the focus will be on keeping the human in the loop. Teaching is, at its core, a deeply human endeavor of connection and empathy. If I can use AI to shoulder the heavy lifting of administrative data processing, I preserve my own "Cognitive VO2 Max." That means I have more energy, patience, and presence to give directly to my students. I’ve also been asked to run a workshop at a tech day for another college, which I’m thrilled about. It’s a great opportunity for outreach and puts our college's innovative practices on the map.

I have a mountain of coursework to grade and paperwork to conquer before the week is out. But the sun is shining, the systems are functioning, and we are moving forward. One step—or one audiobook—at a time.

The Science of Systems: From White Papers to Caffeine Crashes By a Stoke-on-Trent SEND Teacher

The life of a teacher is rarely linear. It is a chaotic, oscillating wave of energy management, data input, and emotional regulation. This weekend, that wave peaked with my daughter’s birthday party. It was a garden party—or at least, an attempt at one—amidst the British weather. It was a success, filled with the chaotic joy of school friends and cousins, but it resulted in a late night and a deep, permeating fatigue.

As I sat there yesterday, recovering from the social whirlwind, I realized that my personal energy crisis mirrored a much larger systemic shift happening in our profession. Just as I am trying to regulate my own biological systems, the government is attempting to regulate the complex ecosystem of Special Educational Needs and Disabilities (SEND).

The New White Paper: A System Reset?

The government has launched its new White Paper on SEND reforms. I’ll be honest with you: I haven't read the 100-plus pages myself. For a dyslexic brain like mine, a government PDF is less of a document and more of a "cognitive marathon." I see a wall of text, and my brain initiates a shutdown sequence. Instead, I rely on my network—like the breakdown provided by 'Mr. P' online—to decode the signal from the noise.

From what I’ve gathered through my audio-first approach, there is reason for cautious optimism. The proposal suggests funding might go directly to schools, bypassing some of the bureaucratic bottlenecks that currently strangle local authorities. There’s talk of replacing the battleground of Education, Health and Care Plans (EHCPs) for some students with "Individual Support Plans" (ISPs).

To put my scientist hat on, this reminds me of James Lovelock’s Gaia hypothesis: the idea that a system is self-regulating. Currently, the SEND system is in disequilibrium. We know from Department for Education (DfE) data that the demand for EHCPs has skyrocketed by over 50% since 2019, creating a backlog that leaves vulnerable children in limbo. If this White Paper can streamline the resource exchange—much like the carbon exchange I used to study between soil and atmosphere—we might actually see nutrients (funding and support) reaching the roots (the children) faster.

My friend, another pragmatic teacher, is skeptical. He sees it as merely shifting the administrative load onto schools. But I choose to channel a bit of Ernest Shackleton here. We are in the ice; we have to believe there is a way through. The fact that they delayed the release to consult with parents and experts suggests they weren't just ticking a box. They were actually testing the soil before planting the crop.

The Biological Machine: Caffeine and Consequences

While I contemplate national policy, I am also forced to confront my own internal policy on energy consumption. Yesterday, fueled by party fatigue, I made a tactical error. I consumed a sugar-free Monster Energy drink and several coffees late in the day.

The result was scientifically predictable, yet I ignored the data. Caffeine has a half-life of about five to six hours. Drinking it in the afternoon meant that when I tried to sleep, my adenosine receptors—the chemical catchers in the brain that tell us we are tired—were still being blocked. I tossed, turned, and had vivid, restless dreams.

As Tim Ferriss often argues, we have to treat our bodies like experiments. My experiment failed. Today, I am paying the "sleep debt." It reinforces the old adage: You can't pour from an empty cup. In the caring professions, we are biologically wired to help others, often at the expense of our own homeostasis. But without "self-repair"—getting back into a routine, cutting caffeine after lunch, and prioritizing sleep—we become inefficient machines.

Chemistry and Climate: The Serotonin Connection

It’s not just the caffeine. For the last month, I’ve been on Sertraline. It’s a decision I didn't take lightly, but one that has provided a necessary buffer. I view it through the lens of atmospheric chemistry. Sometimes, the cloud cover is too thick for too long, and you need a chemical catalyst to help the sunlight break through.

And speaking of sunlight, can we talk about the weather in Stoke? We have just endured what feels like the wettest January and February on record. The Met Office confirms that rainfall in some parts of the UK has been 200% of the average. The ground is sodden, a muddy slurry that mirrors how a dyspraxic brain feels on a bad day.

But Sunday offered a glimpse of blue sky. The temperature rose, I shed my jumper, and for an hour, I felt the immediate physiological shift. Sunlight triggers the release of serotonin. It is a primitive, biological reset. It reminded me that we are not separate from our environment; we are part of it. A little blue sky can change a mindset more effectively than any professional development course.

The Productivity Lab: PPA and Marginal Gains

Today, I have my PPA (Planning, Preparation, and Assessment) time. The pressure is on to submit data—likely the CSV files for Key Stage tracking—and I know there are gaps I haven't prepared for. This is where the dyslexia kicks in again; data entry is my kryptonite.

To combat this, I’m turning to the "Aggregation of Marginal Gains," a concept popularized by Sir Dave Brailsford of British Cycling. The idea is simple: if you improve every tiny aspect of a process by just 1%, the cumulative effect is massive.

I’m applying this to my PPA:

 * Environment: Finding a quiet corner (reducing variable noise).

 * Audio: Instrumental music only. I can’t process lyrics while writing. John Williams is my go-to. There is something about the Star Wars score that lends an epic sense of purpose to grading papers.

 * Habits: I’ve been listening to James Clear’s Atomic Habits. I’m looking for that 1% improvement in how I structure my time.

I realised today that I actually need training on how to use PPA effectively. We are taught how to teach, but rarely how to manage the administrative beast that sits behind the teaching. That is a gap in my own professional toolkit I need to fill.

The Human Element: Creating a Culture of Belonging

Ultimately, whether we are talking about government White Papers, brain chemistry, or productivity hacks, the goal is the same: to create an environment where growth can happen.

I’ve been focusing recently on positive reinforcement in "the shop" (our vocational learning space). I realised that my strongest tool isn't my scientific knowledge, but my ability to spot the positives. When I explicitly told the students yesterday how much they had improved—showing them the data of their own progress—the atmosphere changed.

This is the Pygmalion Effect: high expectations and positive reinforcement lead to improved performance. It created a culture of camaraderie. Everyone thrived.

So, as I head into this PPA session, fueled by less caffeine and more determination, I’m holding onto that. We are all just complex systems trying to find balance—whether that’s balancing a national budget for SEND, or balancing the neurotransmitters in our own tired heads.

Mind the Gap: From Virgin Media Bills to the AI Frontier

It’s a biting morning here in Stoke-on-Trent. The car thermometer struggled to hit 1°C, and while there wasn’t quite enough frost to turn the world white, the air has that sharp, crystalline sting that makes you retreat into your coat. We’re fast approaching the "Week of Doom"—that mid-term slump where the initial energy of the New Year meets the cold, grey reality of February.

As a SEND teacher with a background in Natural Science, I often view life through the lens of systems. Whether it’s the exchange of carbon between our British peat bogs and the atmosphere, or the way a student decodes a sentence, everything is a process of inputs, barriers, and outputs. Lately, however, my focus has shifted from environmental systems to our rapidly evolving digital ones. Between a personal mission to help an elderly relative and the explosive rise of Artificial Intelligence, I’m seeing a gap widening in our society—a digital chasm that we ca

n no longer afford to ignore.

The Hidden Cost of the "Digital Default"

Yesterday, I was at my partner Sarah’s mother’s house. She belongs to a generation where a landline isn’t just a utility; it’s a lifeline. We were there to meet an engineer to fit a backup phone for emergencies—a necessary redundancy. But while we were sorting the hardware, we took a long, hard look at the software: specifically, the billing.

We discovered she was being charged £127 per month by Virgin Media for a standard TV, broadband, and phone package. After a firm conversation explaining her circumstances and challenging the "loyalty tax" so often imposed on long-term customers, we got that bill down to £57.

> The Maths of Advocacy: That is a saving of £70 a month, or £840 a year.

> 

For someone on a fixed income, that isn’t just "spare change." That is the difference between heating and eating. It made me wonder: how many thousands of people are currently being ripped off simply because they lack the digital confidence or the "executive functioning" to challenge these massive corporations?

The Office for National Statistics (ONS) has highlighted that while internet use is increasing among the silver generation, a significant "digital divide" remains. Recent reports from Age UK suggest that millions of over-65s are still digitally excluded. When banks close their physical branches and move everything behind a login screen, we aren't just modernising; we are disenfranchising a segment of our population. It’s a systemic failure that treats a basic necessity as a luxury, mirroring the "poverty premium" where those with the least often end up paying the most.

The "Cognitive Marathon" and the AI Chasm

As someone who is both dyslexic and dyspraxic, I’ve had my own "lightbulb moment" with technology. For years, reading was what I call a "cognitive marathon." I would spend so much energy simply decoding symbols—mixing up "is" and "are," or reading a whole page and absorbing zero information—that by the time I reached the end, I had no mental energy left for actual comprehension.

Then, while gardening one afternoon, I listened to an audiobook. It changed everything. By bypassing the decoding struggle, I freed up my brain to actually learn. I wasn't lazy; I just needed a different input method. This reflects the Universal Design for Learning (UDL) framework: if a variable is a bottleneck, you remove it to optimise the output.

Now, however, we are entering a world of AI Stratification. If the digital divide was a crack in the pavement, the rise of Generative AI is a tectonic shift creating a canyon. We are seeing two distinct classes emerge:

 * The AI Elite: Those who can afford premium subscriptions and have the literacy to use these tools as "cognitive prosthetics."

 * The Digitally Displaced: Those who struggle to even attach a document to an email.

In the classroom, our instinct is often to ban AI over concerns about safeguarding or "cheating." While valid, I fear we are doing students a massive disservice. If we send them into a world where AI is the standard tool of the trade without teaching them how to use it safely, we are sending them into a blizzard without a coat.

The Power and the Peril

I’ve been experimenting with these tools myself. A colleague recently asked if I could use AI to place their sister-in-law into various movie scenes for a big birthday. I’ve created nearly 300 images—putting her into Star Wars, Indiana Jones, and standing next to global landmarks.

It’s harmless, whimsical fun. But as a scientist, I can’t help but see the underlying mechanism. It is effortless. This speed of iteration is something we haven't seen since the Industrial Revolution. In my previous career studying permafrost, change happened over millennia; here, it happens in milliseconds.

This brings me to the "Spider-Man Principle": With great power comes great responsibility. If I can place a friend in a film for a laugh, a bad actor can place a professional in a compromising position with the same ease. We are entering an era where a reputation built over thirty years can be destroyed in thirty seconds by a deepfake. In science, we talk about "irreversible processes"—and a ruined reputation in the age of AI is exactly that.

Literacy as a Lifeline

So, what is the solution? Like the changing climate, we cannot "un-invent" the technology. We must adapt our social ecosystem to survive it. We need to build resilience—much like the Shackleton expeditions—showing fortitude in the face of an environment shifting beneath our feet.

As a SEND teacher, I advocate for AI Literacy as a core life skill. We need a society-wide intervention that covers:

 * Verification Skills: Learning how to spot AI "hallucinations" or fakes.

 * Executive Functioning Hacks: Using AI for organisation and accessibility.

 * Ethics: Using tools to build and create, rather than degrade or deceive.

We must ensure our elders are not left behind in the cold, and that our students are equipped to navigate a world where the line between "real" and "rendered" is permanently blurred. The goal is to move forward safely. I’ll keep fighting the corner for my students and making sure Sarah’s mum isn’t paying for a "loyalty" she never asked for.

Stay warm, stay curious, and most importantly, stay sceptical.
