It was there that the gifted mathematical students of Year 9 used Roamer in an after school project: Designing and Modelling Bus Routes. This is their report. (more…)
In 1987 Bradford teacher Doreen Gregory inspired me to design an educational version of Big Trak. That was Classic Roamer. Tomorrow the world’s greatest cycle race, the Tour de France starts in my home town of Leeds.

What is an algorithm? An algorithm is a set of step-by-step actions that will solve a problem. This definition does not adequately explain what it really is. In the way of a preview of Roamer and the Computing Curriculum Packages, I will try and add some substance to the answer and I will provide a simple Roamer activity that will show you how you can teach the concept in a concrete practical way.
