The problem with problem solving

I believe Albert Einstein was once asked “If you have one hour to save the world, how would you spend that hour?”He replied, “I would spend 55 minutes defining the problem and then five minutes solving it.”When asking 20 mathematics teachers to define problem solving you are likely to get 21 different definitions. In its recent report Problem...

Perfect problem solving with Bojagi

As a mathematics teacher, I like to start the term with some basic number skills with my KS3 groups. This choice is grounded in solid reasoning: check the pupils have got a grasp of the basics before moving on to another topic. Prime factor trees make great display work, and Pascal’s Triangle can have the ‘wow’ factor. But how else can that start-of-the-new...

Problem solving in computing and across STEM - part 1

UK students are good problem solvers. PISA tests reveal that they are better than most international peers, including those from countries with better performance in mathematics and reading. Can this help their achievement in computing and other STEM subjects?This series of articles explores problem solving in computing and across STEM, asking ‘what is...

Problem solving in computing and across STEM - part 2

In part 1 we discovered that STEM subjects have common practices that can be shared and taught in the same way to reinforce and improve students’ learning. In part 2 we look at a possible approach to problem solving in computing and how this touches other STEM subjects.Solving problems in computing – a possible approachComputers process data. Problem...

Problem solving in computing and across STEM - part 3

Our previous articles (part 1 and part 2) have looked at how problem solving is used in STEM subjects and the skills that can be transferred to other subjects to improve learning.In part 3 we learn how debugging can be utilised in other lessons as well as posing questions we as teachers should all be thinking about…Debugging – evaluation and testing in...

How do you solve a problem like girls in physics?

Three years ago my colleagues and I sat down to discuss how we could, in our own small way, help to tackle the problem of a low uptake of A level physics by girls. The result was a termly event called Girls in Physics.The aim of this evening event is to create a space for girls to network with each other, to meet students with similar interests, and to...

Fixperts: teach your students to design for impact

We’re experiencing a global revolution in how things are made. It includes everything from new digital technologies like 3D printing, to internet-based tools for design collaboration, distribution, and improvement. It’s influencing where we get our ideas and how we choose to make them real. Add finite resources, shifting global markets,...

Language, truth and logic

Written by: Greg Michaelson, Heriot Watt University.It’s curious how discussions about teaching programming often descend into arguments about the merits of different programming languages, especially for beginners.Right now, the main divide seems to be between visual languages, like Scratch, BYOB and AppInventor, and textual languages, like Python or Java....

Water: a calculated resource in mathematics

There are many water-based problems to be found in mathematics classrooms. How many times have you posed questions about filling up water containers, and then matching them with a depth-time graph?Then there is the well-known problem below:Two friends who have an eight-quart jug of water wish to share it evenly. They also have two empty jars, one...

Mathematics: an important ingredient in the new design and technology qualifications

For those teaching the new design and technology and engineering specifications from September 2017, one of the most interesting changes to the examined content is the increased focus on mathematics knowledge. How would you or your students fare with the following question?A water feature is made from three buckets A, B and C. Each bucket fills with...
