6 Easy Techniques Computing Teachers Can Actually Use To Teach Programming

Programming is a learned skill that can be improved with practice. Sure there are some who find it easier than others but that is the same with any subject or skill.

You only need to look at the sporting world and recognise the likes of Ronaldo or Messi to see that some people will excel in a skill that others find harder to get to grips with. That does not mean that all the children who don’t have a natural talent should never be given a football to kick against a neighbour’s wall, they just need a little help in finding their feet – excuse the pun!

Programming is no different, you will have pupils who are happy, and indeed relish the opportunity, to work through a page of programming problems. You will equally find others who find programming problems daunting and need other techniques to help them gain confidence in their ability to tackle programs by building up their computational thinking skill set and learning the necessary syntax.

Here are six tried and tested techniques you can use in your classroom straight away that can help all your pupils embed their new found skills and perhaps even enjoy the problem solving side of programming.

How can you teach pupils to program?

1) Use live coding

Instead of only having programs already created and ready to be displayed in a PowerPoint presentation, it can help your class to see you type in your programs live, with your screen being projected onto the whiteboard.

This allows you to talk through each stage as you create it and allows pupils to ask “What if…” questions. It also gives them a sense of how you create your programs (i.e. top down etc) and learn the keyboard shortcuts you may use.

This method also has the added benefit of slowing you down which allows the pupils to process your programs and reduces the risk of somebody getting left behind when you simply talk through a slideshow.

2) Make predictions

Ask the pupils to predict the output of programs (either as you type them using the technique above or from a pre-created program that they are given time to read through and process before they are required to give an answer). Ideally their prediction should be recorded publicly, either by voting (electronically or by simply using a show of hands) or by writing it on a whiteboard.

The pupils who get it wrong are prompted to pay more attention, but you must be careful not to punish or criticise students who predicted wrongly and instead use it as a stepping stone to further exploration of why they got it wrong or made the wrong assumption.

3) Paired programming

When using paired programming, it is important to put everyone in pairs, not just the learners who may be struggling, so that no one feels singled out.

Two pupils need to share a computer for this technique to work. One is in charge of the typing whilst the other offers suggestions. They need to swap roles regularly and it helps to announce when they need to swap to the class.

Both students in the pair learn while doing it. A weaker student gets individual instruction from the other, while the stronger student embeds their knowledge by having to explain what they are doing and by being forced to consider things that they may not have thought about.

4) Remember what they already know

Expert programmers have a wealth of skills and knowledge to draw upon whereas students who are just starting to learn programming only have a very narrow skill set. When they are given a problem to solve it will not be second nature to know how to break it down.

Your pupils will need time to look back on other programs they have created, or code they are familiar with to see which parts can be reused. By giving them an earlier program they have created as a starting point, and asking them adapt it, your pupils can see how their new skills are scaffolded by earlier skills which helps embed the new knowledge they are gaining.

5) Type what they say

This technique involves the pupils telling you how to solve a programming challenge. Set the class a problem and then nominate one pupil to tell you what to enter so you can complete the program. You may want to bounce it around the class or stick to a single instructor but the trick here is to type in EXACTLY what they say and nothing more.
