Today, we get to know our educator, Edmund! He is a common sight in many of our Python classes, and it's hard to miss his hearty laughter when you're on our campus. Armed with a Masters in Mathematics, Edmund is always jovial and ready to lend a helping hand to his students.

Hi Edmund, what was your first encounter with coding like?

I would say that my very first experience with coding was during my tertiary days when I went to find out how to create a game similar to MapleStory with added features like PVP (player versus player) to play with my friends.

Cool! Did this inspire you to take Mathematics in university?

Since young, I have always loved solving challenging problems and I wanted to know more behind mathematical concepts. I competed frequently in Primary and Secondary school at the Australian Mathematics Competition (AMC), International Competitions and Assessments for Schools (ICAS) as well as the National Mathematical Olympiad of Singapore ( NMO∑) where I scored Distinctions and won various awards for my school. Thus, it was only natural that I went on to complete a Masters programme in Mathematics. My Math background led to a strong understanding of Computer Science as I was exposed to programming languages such as MATLAB and R. The training I underwent enabled me to fully understand the reasoning and process of mathematical concepts. With that, I am able to explain to my students exactly what we are coding when I teach.

Wow! Okay, so are there any differences or similarities between the studies of Mathematics and Computer Science?

Coding is very similar to Mathematics where we make use of our problem-solving and logical skills. The thinking processes for both are very similar. The thinking and algorithmic logic is more important than which programming language we choose to use when coding (there are many that go in and out of fashion). Also, coding problems often require the usage of math. For instance, to code up a function that calculates x and y coordinates of a point might require mathematical concepts such as the Pythagoras Theorem. Many students we put up for the National Olympiad in Informatics also have very strong background in Math Olympiad. The two are indeed deeply connected.

So how did you go from Mathematics to teaching coding?

I always enjoyed teaching and instructing. During my National Service, I was an instructor for the National Civil Defence Cadet Corps (NCDCC). I taught my recruits lifesaving skills, brought them through foot drills and exposed them to outdoor adventure activities. It was a great motivation to see my cadets' faces light up with joy and pride when they graduated from a course or successfully completed an activity. Even before my National Service, I was an assistant teacher for an enrichment programme provider which held quality programmes and holiday camps for preschools to secondary levels. So, I guess it was quite natural for me to move towards a career in teaching.

I heard that you taught yourself Python, which is pretty impressive! Could you take us through what that was like?

Before I joined Coding Lab, I learnt Python with the help of online platforms like YouTube! I was interested to know more about programming languages and researched online. I found out that Python was one of the most widely used languages. Then, I spent many hours watching tutorials, some videos were even 13 - 17 hours long, where I had to watch them at 2x speed. :)

When I became an Educator, it greatly helped that Coding Lab has very comprehensive teaching materials for Educators to grasp, practice and stay abreast of the latest curriculum and the community we build with other fellow tutors and students is a warm, close-knit one. I'm glad that I could easily depend on my teammates to help out if I needed anything!

Coding excites me, especially when I have spent a long time trying to debug a program and it finally works. This satisfaction is what I seek to inspire in my students for them to excel in coding!

What do you like best about teaching coding?

The best part about teaching coding is that I am able to continue learning even while I am teaching. You will be amazed at how creative and innovative the students can be with their ideas and the way they code. Some of them even have ideas that I would never have thought of!

I always try my best to make my lesson fun and enjoyable. For instance, I'll relate the lesson to topics that the students are into, making it more interactive. Sometimes I even use terms and references from games they play, or popular and trending videos they are likely to watch!

I personally think that kids should learn how to code as technology is always advancing. Understanding how computers work and learning to code helps them appreciate how things work and the ability to solve problems is a life skill that will stay with them!

We all know that motivating children can be tough, so how do you do it?

I believe that encouragement motivates people. A little goes a long way and every small encouragement will make the student feel more motivated to continue coding. I set goals for my students and support them in meeting those goals and even challenge them to go even further.

What is your most memorable teaching experience thus far?

My best teaching experience at Coding Lab so far would be one class where my students were all fans of the online comedian character, Uncle Roger, who makes parodies of cooking shows. We had programs done by the students under humorous names like "Egg Fried Rice". They even compared me, "Uncle Edmund", to "Uncle Roger"! It was a lot of fun and laughter while still being able to teach the skills and know-how of Python.

Do you intend to continue teaching coding in the future?

Definitely! In fact, ever since I started coding and teaching it, I have a slight regret of not taking more modules in Computer Science during my Masters. I'm glad to be at Coding Lab, where I have the opportunity to pick up as much coding as I want and even impart this to many others. Coding excites me, especially when I have spent a long time trying to debug a program and it finally works. This satisfaction is what I seek to inspire in my students for them to excel in coding!

Finally, what do you enjoy doing in your free time?

I am still a volunteer with the NCDCC. It was through this organisation that I had the opportunities to learn so many skills (lifesaving, rescue, outdoor adventure, etc). I've had many memorable experiences in the Corps. I once mentored a cadet who almost went astray due to family issues and bad company. He felt unappreciated back home and felt that he was being forced to attend the course that he had no interest in. I told him that if he wants others to appreciate him, he should first learn to appreciate himself. "Don't try to change others, change yourself," I said. When he graduated from secondary school, he even came back as a Cadet Lieutenant volunteer. On the day of his passing out parade, he asked me to be the one to help put his rank on for him. The moment I buttoned his rank on, I was overjoyed! NCDCC is my way of giving back to the society, by teaching, training and being a role model for the future generation :)

Thank you, Edmund, for taking the time to share your journey with us. We know you will continue to inspire our future generation of coders and be the role model that you already are, as a teacher, mentor, and more!
