| Many students find constructions a difficult topic to grasp. Perhaps it is the addition of extra equipment (compasses, rulers, angle measurers), or the unstructured nature of some of the questions. Alternatively it could be the case that, like me, some students just find such visual topics tricky to master. Dynamic geometry software should never replace paper and pencil. Until exams are set on computers, there will always be a need for students to be able to do things by hand. Perhaps more importantly, as this is how the great mathematical discoveries were made, students should be given the opportunity to see their beauty. But dynamic geometry certainly does have a role to play. It allows us to look deeper at each construction; to instantly change variables, look at why something works, and take one step closer along the road to generalisation. |
