Classic Snake Game with Python Turtle Graphics

Python Turtle Graphics is awesome! It can be used to learn and teach Python programming and Computer Science from elementary to advanced level. There is a post on this blog about the Turtle Graphics demos which come with IDLE (the development environment that ships with Python) – check them out to get an idea of […]

Python Turtle Graphics – Drawing with Stamps

Python Turtle Graphics stamps are awesome. They are not that well known, and learner python programmers often do things in a more complicated way than they need to as a result. Take this classic learner-programmer exercise: Make a chessboard pattern using Python Turtle Graphics. You might want to try the challenge for yourself before continuing […]

A Key Distinction for Better Understanding of Computer Science GCSE and A Level

Do you mean the thing or the container for the thing? In this article I want to discuss a key distinction which crops up again and again throughout Computer Science GCSE and A Level. It is a distinction which might sound trivial or obvious, but many years of teaching have shown me that getting ultra-clear […]

GCSE Computer Science Programming Misses the Mark?

How well does GCSE Computer Science prepare students to become good programmers? I know, programming is not everything, and the other aspects are important too, but still, in the modern world the ability to program well is likely to to give a major advantage in many career paths, and be indispensable in others. So, does […]

Running Python Scripts from a Command Line

There are many ways to run Python code. Many learners begin with IDLE which comes bundled with the standard Python installation. You can go a long way with IDLE but eventually you will want to progress onto different environments. A very common setup for small Python projects is the use of a text editor such […]

Better Typing for Computer Science GCSE and A Level

How good is your typing? This thing with typing is, if you type badly, you will get a lot of practice at typing badly, whereas if you learn to type properly, you will practice typing well every time you do it. The difficulty comes in making the transition from being a bad typist to a […]

Python for GCSE Science and Maths

It often surprises me how little integration there seems to be between Computer Science and other STEM subjects. Just think of the possibilities! Python is the language of choice for working with data in a vast range of professional fields. Astronomy? Of course. Marine Biology? You bet. Financial Analyst? Yep! Wouldn’t it be good to […]

Counting Letters Using a Python Dictionary

Some Python developers would say that there are two fundamental constructs which form the basis of the language: lists and dictionaries. Whether or not that is true, they are both certainly very important. All the GCSE Computer Science specifications mention arrays, and although there are technical distinctions, for many purposes the notion that lists are […]

Tron Classic Arcade Game in Python

In this article we will have more fun and games with the Python Turtle Graphics Module. There are so many things you can do with this module from very basic programs to quite sophisticated applications, making it an ideal learning tool for GCSE Computer Science. One resource based on Python Turtle Graphics that is not […]

Circle Sector Challenge for GCSE Computer Science

Maths GCSE and Computer Science GCSE are often taught very separately, and yet they make excellent companions. Writing a program to explore a topic from Maths can really help to understand the topic deeply as well as providing a great opportunity to practice your coding skills. Here’s a fun challenge to keep your programming skills […]
