Describes an exercise in which senior high school biology students used a computer to simulate genetic mapping. The exercise was designed to enhance the students' grasp of the concepts of linkage and crossing-over. (JR)

Discusses the advantages of basing computer simulations on analogues of nature rather than mathematical models. Explains the concept of heritability and describes how a computer simulation can help undergraduate students understand this concept. (ML)

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)

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. (Author/JN)

Describes an exercise in biometrical genetics based on the noninteractive use of a computer simulation of a wheat hydridization program. Advantages of using the material in this way are also discussed. (Author/JN)

Tutorial computer assisted learning has been successfully introduced in two Open University biology courses. The purpose of the tutorials, how they were designed and written, and students' reactions to them are discussed in the expectation that other teachers will find the technique useful. (Author)
