In Part 1, we spoke to Stephen Parry about his experiences of working in computer science as an autistic person. In this second part, we discuss with him his change from this stressful working environment to teaching A-Level computer science, and how rewarding he has found teaching as a career.

Following a tough experience at his last workplace, Stephen decided he needed a change. He used this as a prompt to start thinking about alternatives:

“[When] things aren’t working out, you need to take a step back and work out what the problem is before it becomes really serious. I still hadn’t had a diagnosis by that point, so things probably would have gone very differently if I had, but I took a step back after that job. I was fed up of being stressed, trying to help people [who] have already got far too much money make more money, and then being told that I was being paid too much. That was kind of my experience from my last employer. And so, I decided that I wanted to get stressed for something worthwhile instead: my mum had been a teacher, so I’d always had it in mind as a possibility.”

Stephen did, of course, have some reservations financially. 

“I’d always thought it was financially too much of a step down, which a lot of people in the computer science industry will find out. I did take pretty much a 50% pay cut to become a trainee teacher: in fact, worse than that. But it’s amazing when you want to do something, what differences that makes! And there’s plenty of people out there that will sacrifice a salary to start their own business, and all the power to them. But people don’t think [like this] when they’re thinking about becoming a teacher, for example, which I think is wrong. Yes, teachers should be better paid than they are, but they’re never going to be as well paid as programmers or team leaders or whatever in industry. You shouldn’t expect that to be the case, because we’re public servants at the end of the day, and we’re here for the job as much as we are for the money. We want our roof over our head, but we’re not looking to get mega rich. We’re there to make a difference.”

While considering this change of profession, Stephen reflected on his existing skills, and whether they fit the role of teaching. With support from his wife and a DWP (Department for Work and Pensions) work coach, he was reminded of his ability to “explain technical stuff to [people] in a language [they] could understand.”

Stephen had the opportunity to get his first experience of teaching as a classroom volunteer. Alongside a qualified teacher, he was able to lead a lesson – which he found particularly exciting:

“It was a bit like being on drugs. It was exhilarating. I sort of sat there thinking, you know, this is something I really want to do.”

It’s around this time that Stephen got his autism diagnosis. For autistic people who receive a diagnosis, there can be a lot of mixed emotions. For some, it can be a huge sense of relief – finally understanding who they are, and how that has affected their actions and behaviours throughout their life. And for others it can come as a shock [EXTERNAL]. For Stephen, this news meant reconsidering his choice of a career in teaching:

“I had to stop and think, because, when you get your diagnosis for the first time as an adult or as an older person anyway, it does make you stop and think about who you are. It does somewhat challenge your sense of self.”

“It kind of turns your world a bit on its head. So, it did knock me a fair bit. It did knock my sense of self. But then I began to sort of put pieces together and realise just what an impact it had on my working life up until that point. And then the question came across, can I still do the job? Am I going to be able to teach? Is it really an appropriate course of action to take? I didn’t get the answer straight away, but certainly over the months and the years, I came to the conclusion it was a bit like when I talk to students who say, ‘should I do computer science?’ And I say to them, ‘well, can you program?’ ‘Yes.’ ‘Yes, you do need to do computer science.’ It’s not just you can if you want to – it’s a ‘you should do CS.’ It’s the same thing if you’re on the spectrum, or you’re in another minority, a significant minority like that, where you’re able to engage with a teaching role: you should do.”

Stephen did go on to complete teacher training, and has now worked as an A-Level and GCSE teacher for 15 years. He still benefits from his time in work, however, as he is able to enlighten future computer science students about the workplace:

“Well, you know the experiences I’ve had as a person in industry, where else are the students going to be exposed to that second-hand? Hopefully they’ll be exposed to it first-hand, but, if I can give them a leg up, and an introduction to that, being forewarned and forearmed and all that, then that’s what should happen. 

“I do spend a chunk of my teaching explaining what it’s like working in industry: explaining the difficulties of dealing with management; (1) when you think you know better, you might not know better – you don’t know yet; (2) if you do, keep your mouth shut until the problem occurs, then offer a positive and constructive solution. Hopefully they won’t say ‘why didn’t you say something sooner?’ If they do, just say, ‘Well, I wasn’t sure it was my place to, I’m only new.’”

Teaching is famously a very rewarding career path, and this is no different for Stephen. In our discussion, he outlined a few things that he enjoyed about teaching:

“It’s [a] situation where what you do, lives on. If I drop dead tomorrow, all that stuff that I learned about; how different procedure calls work or whatever, could potentially just disappear into the ether. But because I’ve shared it with all my students, they will hopefully make use of it, and it will carry on. And it’s a way of having a legacy, which I think we all want, to a certain extent.”

“Young people nowadays, particularly those of us on the spectrum, but it applies to all, the world does everything possible at the moment to destroy most young people’s self-esteem. Really, really knock people flat. Society is set up that way. Our social media is set up that way. Our traditional media is set up that way. It’s all about making people feel pretty useless, pretty rubbish in the hope, in some cases, of selling them something that will make them feel better, which never does, or in other cases, just make someone else feel good by making someone else feel small. It’s kind of the more the darker side of humanity coming out that teaching is an opportunity to counter that. If you can make a young person feel good about themselves; if you can help them conquer something that they’re not able to do; if you could help them realise that it doesn’t matter if they can’t, they’re still just as important and wonderful and valuable as a human being.”

“The extracurricular activities that I do: ‘Exploring the Christian faith’ here at college. And part of that is helping people [to] find a spiritual worth they didn’t realise they had. So, you get that opportunity as a teacher, which a bus driver doesn’t get, for example. Bus drivers are very useful – they do a wonderful job. But once they’ve dropped you off, that’s the end of the job. Sometimes we’re a bit like bus drivers as teachers. You go out the door with your grades, and that’s fine, but then some people keep coming back. I haven’t spotted the existential elastic yet, but it’s there somewhere. I’m sure I didn’t attach it. But that is another one of the things that motivates me to be a teacher.”

Stephen Parry now teaches at a sixth-form college near Sheffield. The author would like to thank Stephen for taking time out of his busy schedule to take part in this interview.

Working in Computer Science: An Autistic Perspective (Part 1)

by Daniel Gill, Queen Mary University of London

Autism is a condition with many associated challenges, but for some people it presents some benefits. This distinction is greatly apparent in the workplace, where autistic people often find it difficult to get along with others (and their boss), and to complete the work that has been set for them. It’s not all negatives though: many autistic people find the work in which they thrive, and given the right circumstances and support, an autistic person is able to succeed in such an environment.

We often rightly hear about the greats in computer science; Ada Lovelace, Alan Turing, Lynn Conway (who sadly passed away earlier this month) – but let us not forget the incredible teams of computer scientists working around the clock; maintaining the Internet, building the software we use every day, and teaching the next generation. For this two-part article, I have spoken with Stephen Parry, an autistic computer scientist, who, after working in industry for 20 years, now teaches the subject in a sixth-form college in Sheffield. His autistic traits have caused him challenges throughout his career, but this is not a unique experience – many autistic computer scientists also face the same challenges.

Stephen’s experience with programming started at the age of 14, after being introduced to computers at a curriculum enrichment course. He decided against taking a then “really rubbish” O-Level (now GCSEs) Computer Science course, and the existence of the accompanying A-Level “just didn’t come up on my radar”. He was, however, able to take home the college’s sole RML 380Z for the summer, a powerful computer for the time, with which, he was able to continue to practice programming.

When it came time to go to university, he opted first to study chemistry, a subject he had been studying at A-Level. Though after a short amount of time he realised that he wasn’t as interested in chemistry as he first thought – so he decided to switch to computer science. In our discussions, he praised the computer science course at the University of Sheffield:

“[I] really enjoyed [the course] and got on well with it. So, I kind of drifted into it as far as doing it seriously is concerned. But it’s been a hobby of mine since I was 14 years old, and once I was on the degree, I mean, the degree at Sheffield was a bit like a sweetie shop. It really was absolutely brilliant. We did all kinds of weird and wonderful stuff, all of it [was] really interesting and engaging, and the kind of stuff that you wouldn’t get by either playing around on your own or going out into [the] workplace. As I’ve always said, that’s what a university should be. It should expose you to the kind of stuff that you can’t get anywhere else, the stuff that employers haven’t realised they need yet.”

Of autistic people who go to university, research shows they are much more likely the general population to pick STEM subjects [EXTERNAL]. For lots of autistic people, the clear logical and fundamental understanding behind scientific subjects is a great motivator. Stephen describes how this is something that appeals to him.

“[What] I enjoy about computer science is how it teaches you how the computer actually works at a fundamental level. So, you’re not just playing with a black box anymore – it’s something you understand. And especially for someone on the [autism] spectrum, that’s a really important aspect of anything you do. You want to understand how things work. If you’re working with something, and you don’t understand how it works, usually it’s not very satisfying and kind of frustrating. Whereas, if you understand the principles going on inside of it then, when you know you’ve got it, it kind of unlocks it for you.”

While autistic traits often result in challenges for autistic people, there are some which can present a benefit to someone in computer science. A previous CS4FN article described how positive traits like ‘attention to detail’ and ‘resilience and determination’ link well to programming. Stephen agrees that these traits can help him to solve problems:

“If I get focused on a problem, the hyper focus kicks in, and I will just keep plugging away until it’s done, fixed or otherwise overcome. I know it’s both a benefit and hazard – it’s a double edged sword, but at the same time, you know you have to have that attention to detail and that, to put it another way, sheer bloody mindedness to be determined that you’re going to make it work, or you’re going to understand how it works, and that does come definitely from the [autism] spectrum.”

Although he enjoyed the content greatly, Stephen had a rocky degree, both in and out of lectures. However, some unexpected benefits arose from being at university; he both found faith and met his future wife. These became essential pillars of support, as he prepared to enter the workforce. This he did, working both as a programmer and in a variety of IT admin and technical support roles. 

About 78% of autistic adults are currently out of work [EXTERNAL] (compared with 20% in the general population). This is, in part, reflective of the fact that some autistic people are unable to work because of their condition. But for many others, despite wanting to work, they cannot because they do not get the support they need (and are legally entitled to) within their workplace.

At this time, however, Stephen wasn’t aware of his condition, only receiving his diagnosis in his 40s. He described how this transition from university to work was very challenging.

“I moved into my first job, and I found it very, very difficult because I didn’t know that I’ve got this sort of difference – this different way my brain works that affects everything that you do. I didn’t know when I came across difficulties, it was difficult to understand why, at least to an extent, for me and for other people, it was deeply frustrating. I mean, speak to just about every manager I’ve ever had, and the same sort of pattern tends to come out. Most of them recognised that I was very difficult to manage because I found myself very difficult to manage. But time management is an issue with everything – trying to complete tasks to any kind of schedule, trying to plan anything. Oh, my days, when I hear the word SMART. [It’s an] acronym [meaning] specific, measurable, achievable, realistic and time specific. I hear that, and it just it makes me feel physically ill sometimes, because I cannot. I cannot SMART plan.”

However, during his time in work, he had some good luck. Despite the challenges associated with autism, some managers took advantage of the positive skills that he brings to the table:

“I found that a real challenge, interpersonally speaking, things like emotional regulation and stuff like that, which I struggle with, and I hate communicating on the phone and various other things, make me not the most promising employee. But the managers that I’ve had over the years that have valued me the most are the ones who recognised the other side of the coin, which is [that] over the years, I have absorbed so much knowledge about computer science and there are very [few] problems that you can come across that I don’t have some kind of insight into.”

This confidence in a range of areas in computer science is also a result of Stephen’s ability to link lots of areas and experiences together, a positive skill that some autistic people have:

“I found that with the mixture of different job roles I did, i.e. programming, support, network admin and database admin, my autism helped me form synergies between the different roles, allowing me to form links and crossover knowledge between the different areas. So, for example, as a support person with programming experience, I had insight into why the software I was helping the user with did not work as desired (e.g. the shortcuts or mistakes the programmer had likely made) and how maybe to persuade it to work. As a programmer with support experience, you had empathy with the user and what might give them a better UX, as well as how they might abuse the software. All this crossover, also set me up for being able to teach confidently on a huge range of aspects of CS.”

For autistic students who are planning on working in a computer science career, he has this to say:

“As an autistic person, and I would say this to anybody with [autism], you need to cultivate the part of you that really wants to get on well with people and wants to be able to care about people and understand people. Neurotypical people get that ability out of the box, and some of them take it for granted. I tend to find that the autistic people who actually find that they can understand people, that they work at it until they can, [are] often more conscientious as a result. And I think it’s important that if you’re an autistic person, to learn how to be positive about people and affirm people, and interact with them in positive ways, because it can make you a more caring and more valuable human being as a as a result.”

“Look for jobs where you can really be an asset, where your neurodiversity is the asset to what you’re trying to do, but at the same time, don’t be afraid to try to, and learn how to engage with people. Although it’s harder, it’s often more rewarding as a result.”

After working in industry for 20 years, the last half as which as a contractor, Stephen decided to take a considerable pay drop and become a computer science teacher. In the second part of this article, we will continue our conversation and find out what led him to choose a career change to teaching.

Designing for autistic people

by Daniel Gill and Paul Curzon, Queen Mary University of London

What should you be thinking about when designing for a specific group with specific needs, such as autistic people? Queen Mary students were set this task and on the whole did well. The lessons though are useful when designing any technology, whether apps or gadgets.

A futuristic but complicated interface
A futuristic but complicated interface with lots of features: feature bloat?

The Interactive Systems Design module at QMUL includes a term-long realistic team interaction design project with the teaching team acting as clients. The topic changes each year but is always open-ended and aimed at helping some specific group of people. The idea is to give experience designing for a clear user group not just for anyone. A key requirement is always that the design, above all, must be very easy to use, without help. It should be intuitively obvious how to use it. At the end of the module, each team pitches their design in a short presentation as well as a client report.

This year the aim was to create something to support autistic people. What their design does, and how, was left to the teams to decide from their early research and prototyping. They had to identify a need themselves. As a consequence, the teams came up with a wide range of applications and tools to support autistic people in very different ways.

How do you come up with an idea for a design? It should be based on research. The teams had to follow a specific (if simplified) process. The first step was to find out as much as they could about the user group and other stakeholders being designed for: here autistic people and, if appropriate, their carers. The key thing is to identify their unmet goals and needs. There are lots of ways to do this: from book research (charities, for example, often provide good background information) and informally talking to people from the stakeholder group, to more rigorous methods of formal interviews, focus groups and even ethnography (where you embed yourself in a community).

Many of the QMUL teams came up with designs that clearly supported autistic people, but some projects were only quite loosely linked with autism. While the needs of autistic people were considered in the concept and design, they did not fully focus on supporting autistic people. More feedback directly from autistic people, both at the start and throughout the process, would have likely made the applications much more suitable. (That of course is quite hard in this kind of student role-playing scenario, though some groups were able to do so.) That though is key idea the module is aiming to teach – how important it is to involve users and their concerns closely throughout the design process, both in coming up with designs and evaluating them. Old fashioned waterfall models from software engineering, where designs are only tested with users at the end, are just not good enough.

From the research, the teams were then required to create design personas. These are detailed, realistic but fictional people with names, families, and lives. The more realistic the character the better (computer scientists need to be good at fiction too!) Personas are intended to represent the people being designed for in a concrete and tangible way throughout the design process. They help to ensure the designers do design for real people not some abstract tangible person that shape shifts to the needs of their ideas. Doing the latter can lead to concepts being pushed forward just because the designer is excited by their ideas rather than because they are actually useful. Throughout the design the team refer back to them – does this idea work for Mo and the things he is trying to do? 

An important part of good persona design lies around stereotypes. The QMUL groups avoided stereotypes of autistic people. One group went further, though: they included the positive traits that their autistic persona had, not just negative ones. They didn’t see their users in a simplistic way. Thinking about positive attributes is really, really important if designing for neurodivergent people, but also for those with physical disabilities too, to help make them a realistic person. That group’s persona was therefore outstanding. Alan Cooper, who came up with the idea of design personas, argued that stereotypes (such as a nurse persona being female) were good in that they could give people a quick and solid idea of the person. However, this is a very debatable view. It seems to go against the whole idea of personas. Most likely you miss the richness of real people and end up designing for a fictional person that doesn’t represent that group of people at all. The aim of personas is to help the designers see the world from the perspective of their users, so here of autistic people. A stereotype can only diminish that.

Another core lesson of the module is the importance of avoiding feature bloat. Lots of software and gadgets are far harder to use than need be because they are packed with features: features that are hardly ever, possibly never, used. What could have been simple to use apps, focusing on some key tasks, instead are turned into ‘do everything’ apps. A really good video call app instead becomes a file store, a messaging place, chat rooms, a phone booth, a calendar, a movie player, and more. Suddenly it’s much harder to make video calls. Because there are so many features and so many modes all needing their own controls the important things the design was supposed to help you do become hard to do (think of a TV remote control – the more features the more buttons until important ones are lost). That undermines the aim that good design should make key tasks intuitively easy. The difficulty when designing such systems is balancing the desire to put as many helpful features as possible into a single application, and the complexity that this adds. That can be bad for neurotypical people, who may find it hard to use. For neurodivergent people it can be much worse – they can find themselves overwhelmed. When presented with such a system, if they can use it at all, they might have to develop their own strategies to overcome the information overload caused. For example, they might need to learn the interface bit-by-bit. For something being designed specifically for neurodiverse people, that should never happen. Some of the applications of the QMUL teams were too complicated like this. This seems to be one of the hardest things for designers to learn, as adding ideas, adding features seems to be a good thing, it is certainly vitally important not to make this mistake if designing for autistic people. 

Perhaps one of the most important points that arose from the designs was that many of the applications presented were designed to help autistic people change to fit into the world. While this would certainly be beneficial, it is important to realise that such systems are only necessary because the world is generally not welcoming for autistic people. It is much better if technology is designed to change the world instead.

Neurodiversity and what it takes to be a good programmer

by Paul Curzon, Queen Mary University of London

People often suggest neurodiverse people make good computer scientists. For example, one of the most famous autistic people, Temple Grandin, an academic at Colorado State University and animal welfre expert, has suggested programming is one of the jobs autistic people are potentially naturally good at (along with other computer science linked jobs) and that “Half the people in Silicon Valley probably have autism.”.. So what makes a good computer scientist? And why might people suggest neurodiverse people are good at it?

What makes a good programmer? Is it knowledge, skills or is it the type of person you are? It is actually all three though it’s important to realise that all three can be improved. No one is born a computer scientist. You may not have the knowledge, the skills or be the right kind of person now, but you can improve them all.

To be a good programmer, you need to develop specialist knowledge such as knowing what the available language constructs are, knowing what those constructs do, knowing when to use them over others, and so on. You also need to develop particular technical skills like an ability to decompose problems into sub-problems, to formulate solutions in a particular restricted notation (the programming language), to generalise solutions, and so on. However, you also need to become the right kind of person to do well as a programmer. 

Thinking about what kind of person makes a good programmer, to help my students work on them and so become better programers, I made a list of the attributes I associate with good student programmers. My list includes: attention to detail, an ability to think clearly and logically, being creative, having good spatial visualising skills, being a hard worker, being resilient to things going wrong so determined, being organised, being able to meet deadlines, enjoying problem solving, being good at pattern matching, thinking analytically and being open to learning new and different ways of doing things.

More recently, when taking part in a workshop about neurodiversity I was struck by a similar list we were given. Part of the idea behind ‘neurodiversity’ is that everyone is different and everyone has strengths and weaknesses. If you think of ‘disability’ you tend to think of apparent weaknesses. Those ‘weaknesses’ are often there because the world we have created has turned them into weaknesses. For example, being in a wheelchair makes it hard to travel because we have built a world full of steps, kerbs and cobbles, doors that are hard to manipulate, high counters and so on. If we were to remove all those obstacles, a wheelchair would not have to reduce your ability to get around. Thinking about neurodiversity, the suggestion is to think about the strengths that come with it too, not just the difficulties you might encounter because of the way we’ve made the world.

The list of strengths of neurodiverse people given at the workshop were: attention to detail, focussed interest, problem-solving, creative, visualising, pattern recognition. Looking further you find both those positives reinforced and new positives. For example, one support website gives the positives of being an autistic person as: attention to detail, deep focus, observation skills, ability to absorb and retain facts, visual skills, expertise, a methodological approach, taking novel approaches, creativity, tenacity and resilience, accepting of difference and integrity. Thinking logically is also often picked out as a trait that neurodiverse people are often good at. The similarity of these lists to my list of what kind of person my students should aim to turn themselves into is very clear. Autistic people can start with a very solid basis to build on. If my list is right, then their personal positives may help neurodiverse people to quickly become good programmers.

Here are a few of those positives others have picked out that neurodiverse people may have and how they relate to programming:

Attention to detail: This is important in programming because a program is all about detail, both in the syntax (not missing brackets or semicolons) but more importantly not missing situations that could occur so cases the program must cover. A program must deal with every possibility that might arise, not just some. The way it deals with them also matters in the detail. Poor programs might just announce a mistake was made and shut down. A good program will explain the mistake and give the user a way to correct it for example. Detail like that matters. Attention to detail is also important in debugging as bugs are just details gone wrong. 

Resilience and determination: Programming is like being on an emotional roller coaster. Getting a program right is full of highs and lows. You think it is working and then the last test you run shows a deep flaw. Back to the drawing board. As a novice learning it is even worse. The learning curve is steep as programming is a complex skill. That means there are lots of lows and seemingly insurmountable highs. At the start it can seem impossible to get a program to even compile never mind run. You have to keep going. You have to be determined. You have to be resilient to take all the knocks.

Focussed interest. Writing a program takes time and you have to focus. Stop and come back later and it will be so much harder to continue and to avoid making mistakes. Decomposition is a way to break the overall task into smaller subtasks, so methods to code, and that helps, once you have the skill. However, even then being able to maintain your focus to finish each method, so each subtask, makes the programming job much easier.

Pattern recognition: Human expertise in anything ultimately comes down to pattern matching new situations against old. It is the way our brains work. Expert chess players pattern match situations to tell them what to do, and so do firefighters in a burning building. So do expert programmers. Initially programming is about learning the meaning of programming constructs and how to use them, problem solving every step of the way. That is why the learning curve is so steep. As you gain experience though it becomes more about pattern matching: realising what a particular program needs at this point and how it is similar to something you have seen before then matching it to one of many standard template solutions. Then you just whip out the template and adapt it to fit. Spot something is essentially a search task and you whip out a search algorithm to solve it. Need to process a 2 dimensional array – you just need the rectangular for loop solution. Once you can do that kind of pattern matching, programming becomes much, much simpler.

Creativity and doing things in novel ways: Writing a program is an act of creation, so just like arts and crafts involves creativity. Just writing a program is one kind of creativity, coming up with an idea for a program or spotting a need no one else has noticed so you can write a program that fills that need requires great creativity of a slightly different kind. So does coming up with a novel solution once you have a novel problem. Developing new algorithms is all about thinking up a novel way of solving a problem and that of course takes creativity. Designing interfaces that are aesthetically pleasing but make a task easier to do takes creativity. If you can think about a problem in a different way to everyone else, then likely you will come up with different solutions no one else thought of.

Problem solving and analytical minds: Programming is problem solving on steroids. Being able to think analytically is an important part of problem solving and is especially powerful if combined with creativity (see above). You need to be able to analyse a problem, come up with creative solutions and be able to analyse what is the best way of solving it from those creative solutions. Being analytical helps with solid testing too.

Visual thinking: research suggests those with good visual, spatial thinking skills make good programmers. The reasons are not clear, but good programs are all about clear structure, so it may be that the ability to easily see the structure of programs and manipulate them in your head is part of it. That is part of the idea of block-based programming languages like Scratch and why they are used as a way into programming for young children. The structure of the program is made visual. Some paradigms of programming are also naturally more visual. In particular object-oriented programming sees programs as objects that send messages to each other and that is something that can naturally be visualised. As programs become bigger that ability to still visualise the separate parts and how they work as a whole  is a big advantage.

A methodological approach: Novice programmers just tinker and hack programs together. Expert programmers design them. Many people never seem to get beyond the hacking stage, struggling with the idea of following a method to design first, yet it is vital if you are to engineer serious programs that work. That doesn’t mean that programming is just following methods, tinkering can be part of the problem solving and coming up with creative ideas, but it should be used within rigorous methodology not instead of it. More time is also spent by good programming teams testing programs as writing them, and that takes rigorous methods to do well too. Software engineering is all about following rigorous methods precisely because it is the only way to develop real programs that work and are fit for purpose. Vast amounts of software written is never used because it is useless. Rigorous methods give a way to avoid many of the problems.

Logical thinking: Being able to think clearly and logically is core to programming. It combines some of the things above like attention to detail, and thinking clearly and methodologically. Writing programs is essentially the practice of applied logic as logic underpins the semantics (ie meaning) of programming languages and so programs. You have to think logically when writing programs, when testing them and when debugging them. Computers are machines built from logic and you need to think in part like a computer to get it to do what you want. A key part of good programming is doing code walkthroughs – as a team stepping through what a program does line by line. That requires clear logical thinking to think in teh steps the computer performs.

I could go on, but will leave it there. The positives that neurodiverse people might have are very strongly positives for becoming a good programmer. That is why some of the best students I’ve had the privilege to teach have been neurodiverse students.

Different people, neurodiverse or otherwise, will start with different positives, different weaknesses. People start in different places for different reasons, some ahead, some behind. I liked doing puzzles as a child, so spent my childhood devouring logic and algorithmic puzzles. That meant when I first tried to learn to program, I found it fairly easy. I had built important skills and knowledge and had become a good logical thinker and problem solver just for fun. I learnt to program for fun. That meant it was if I’d started way beyond the starting line in the race to become a programmer. Many neurodiverse people do the same, if for different reasons.

Other skills I’ve needed as a computer scientist I have had to work hard on and develop strategies to overcome. I am a shy introvert. However, I need to both network and give presentations as a computer scientist (and ultimately now I give weekly lectures to hundreds at a time as an academic computer scientist). For that I had to practice, learn theory about good presentation and perhaps most importantly, given how paralysing my shyness was, devise a strategy to overcome that natural weakness. I did find a strategy – I developed an act. I have a fake extrovert persona that I act out. I act being that other person in these situations where I can’t otherwise cope, so it is not me you see giving presentations and lectures but my fake persona. Weaknesses can be overcome, even if they mean you start far behind the starting line. Of course, some weaknesses and ways we’ve built the world mean we may not be able to overcome the problems, and not everyone wants to be a computer scientist anyway so has the desire to. What matters is finding the future that matches your positives and interests, and where you can overcome the weaknesses where you set your mind to it.

Programming is not about born talent though (nothing is). We all have strengths and weaknesses and we can all become better by practicing and finding strategies that work for us, building upon our strengths and working on our weaknesses, especially when we have the help of a great teacher (or have help to change the way the world works so the weaknesses vanish).

My list above gives some of the key personal characteristics you need to work on improving (however good at them you are or are not right now) If you do want to be a good programmer. Anyone can become better at programming than they are if they have that desire. What matters is that you want to learn, are willing to put the practice in, can develop strategies to overcome your initial weaknesses, and you don’t give up. Neurodiverse people often have a head start on those personal attributes for becoming good at new things too.
