"The following example is a piece of work about simplifying algebraic fractions that illustrates the value of student explanations. The task was to make a video explaining how to simplify the three fractions below, complete with full explanations. No training was given on how to do this, and no apps were recommended. This was my first attempt at asking this particular group of students to create a video. It follows that after years of simply writing down answers and them either being right or wrong, several students decided to assume that I was joking with this task and simply handed me in a copy of the answers. Job done. Or was it Wolfram Alpha's job done? Anyway, here is what a few responses to the task looked like"

"The Raspberry Pi is a mini computer that was specifically created to make tech learning easier. It has a lot of components for computer-based projects, like USB ports, an ethernet port, an SD card slot, Wi-Fi antenna ports, and more. It does not come with peripherals, like cables, a keyboard, a mouse, or a monitor. It is a great for learning program languages, like Python, Scratch, and Wolfram. Most Raspberry Pi enthusiasts like making single-process builds to show off their do-it-yourself talents. For example, you could create a dedicated gaming device, or an external storage box for movies and music. There are a plethora of Raspberry Pi Projects that cover all manner of possibilities, each one with different specifications. We have a guide for getting started with Raspberry Pi to help you understand what you will need for your first (or next) project. "

Coding is the enemy of computational thinking," Stephen Wolfram announced during his keynote at the Building Learning Communities® Education Conference. What was remarkable about this comment were the agreeable nods from the crowd. It seemed there was a collective understanding to this notion, and perhaps one that needed further reflection. This year, the conference had several sessions focusing on computational thinking (which, I might add, is incredibly encouraging to see), and in each one I attended, a special note was added: "Coding and computational thinking are not synonymous."

"There is a lot of talk of "Computational Thinking" as a new imperative of education, so I wanted to address a few questions that keep coming up about it. What is it? Is it important? How does it relate to today's school subjects? Is Computer-Based Maths (CBM) a Computational Thinking curriculum? Firstly, I've got to say, I really like the term. To my mind, the overriding purpose of education is "to enrich life" (yours, your society's, not just in "riches" but in meaning) and different ways in which you can think about how you look at ideas, challenges and opportunities seems crucial to achieving that. Therefore using a term of the form "xxx Thinking" that cuts across boundaries but can support traditional school subjects (eg. History, English, Maths) and emphasises an approach to thinking is important to improving education."

" I heard a great talk a few months ago. It was Conrad Wolfram (probably one of the world's leading mathematicians) who suggested, that we should stop teaching our kids maths. Whoah! He said, and I'm paraphrasing, we needed to teach them computational thinking instead. What is that? He said every problem needs breaking apart, exploding it into its parts - if we are to begin to properly solve them. And better still that we explain to kids how to put that idea into practice. Explain to them, for example, that to make their bike go faster they might figure out how much bigger the peddle wheel needs to be than than the one on the back wheel. According to Wikipedia computational thinking is an iterative process based on three stages: 1. Problem formulation (abstraction) 2. Solution expression (automation) 3. Solution execution and evaluation (analyses) That REALLY works for me."
