When students make the transition from one curriculum to another, with significant overlap of content, the challenge is not so much to impart new information but rather to tap into students' existing knowledge base. The purpose of this study was to determine if achievement in an external examination that requires analysis could be enhanced by the…

The educational design of a project option in an Open University course on evolution is described. Also described is the simulation which models the genetic and evolutionary consequences of two populations of a species of flowering plant coming together after a period of genetic isolation.

A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

An evaluation study comparing a computer assisted learning-based project with three more conventional ones in an Open University course on evolution is reported. Special attention is paid to reasons why students chose to do different projects and the factors contributing to the variance in the marks awarded for their work. (Author/JN)
