The use of mobiles to illustrate a number of basic principles in ecology teaching is rewarding, particularly with less able pupils, and an attractive end-product to decorate the biology laboratory is a bonus.

Gametophytes are easily cultured, even with limited facilities. They can he used to illustrate not only the alternation of generations in plant life cycles but also aspects of reproduction and development not easily studied with other plant material. The approach can be adjusted to the needs of biology and botany classes over a wide range of experience from secondary school to university. Information is presented on: the choice of species; the collection, storage and sowing of spores; the composition of the medium; light and temperature requirements; sampling and staining techniques; and methods for determining quantitative parameters of cell and gametophyte development. The basic fern life cycle, and modifications such as apogamy, are outlined. Attention is drawn to the main features of the reproductive biology of ferns and appropriate investigations are suggested. The advantages of gametophytes as experimental material for studying cellular aspects of development in intact green plants are explained. They include striking but consistent responses to a range of cultural conditions and environmental treatments. Suggestions are given for investigations to stimulate further discussion of a wide range of developmental events.

This paper reports the design of an interactive computer program in microbial genetics. The computer program is divided into three stages, background information, simulation, and data treatment. The results obtained from the simulation allow four genes to be sequenced along the bacterial chromosome. The simulation mimics experimental errors, the production of exconjugants and backmutants. The data can be analysed using options contained in the program. The simulation is of particular educational value because it allows the student to work at his own pace and to develop his ability to analyse data in relation to a complex conceptual model.

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' reaction to them are discussed in the expectation that other teachers will find the technique useful.
