Reduced GUI for an interactive geometry software: Does it affect students' performance?
We investigated whether a reduced interface of an interactive geometry software helps to increase students' performance. We designed 60 tasks to be completed with two different interfaces, a complete and a reduced version, for the same software. We carried out an experiment involving 69 undergraduate students, randomly assigned to one of the interfaces. The experimental results indicate that the reduced interface helps novice users to perform slightly better. After receiving proper training, however, a complete interface makes users more productive using a complete interface.
