Methods of investigating plant root growth developed for research purposes can be adopted for student use. Investigations of the effect of water table level and of ethylene concentration are described, and techniques of measuring root growth are explained. (Author/ML)

Describes results and experiences of four field-course experiments designed to explore the relationships between animals and their physical environment. Reports on the response of animals to flow rate of water, relationship between size and rate of locomotion, and mathematical and physical techniques used to study how animals live. (RT)

This paper describes a simple, rapid and low-cost technique for growing bacteria (or other microbes) in an environmental gradient, in order to determine the tolerance of the microbial population to varying concentrations of sodium chloride ions, and suggests how the evolutionary response of a microbial population to the selection pressure of the…

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)

Perspectives are domain-specific strategies employed by experts in a specific field to formulate and investigate questions. Such strategies may therefore serve as good models for acquiring knowledge. Based on this premise, we developed the perspective of form and function, as used by both biologists and technical designers, into a tool for…

Reports on a survey which was undertaken to provide an overview of the biology content of a selection of General Certificate of Secondary Education science syllabuses. Lists syllabuses examined and the four themes in terms of which they were analyzed. Concludes that each contained a substantial biology component. (RT)

An educational package based on the Messolongi wetland area and designed to develop environmental awareness amongst Greek secondary students is described. The package includes a book and a pedagogical guide for the teacher, as well as a hypermedia application/CD-ROM and worksheets for the student. The entire educational package combines recent…

This article presents a brief history of the events leading up to the current US biology education standards, a brief examination of the National Science Education Standards for biology, and a description of the three recently developed biology curricula that were designed to address the new standards. Several evaluative studies of these curricula…

From September 2006 schools across England and Wales will have to deliver the new KS4 Programme of study. The wide consultation initiated by the Qualifications and Curriculum Authority (QCA) in the year 2000 resulted in the piloting of the new criteria in 78 different schools and colleges. The piloting was performed by the awarding body Oxford…
