In today’s technology-rich world, many schools have begun teaching coding, the language we use to instruct today’s computers. It’s a skill that is in high demand, and there are intriguing examples of schools across the world teaching it in ways that are relevant and engaging for students. But the risk is that we will again be teaching students today’s techniques to solve tomorrow’s problems; by the time today’s students graduate, these techniques might already be obsolete. We should instead focus on the computational thinking that underpins these techniques – and that students can use to shape the technologies of tomorrow.
