Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)

The results of surveys of biology staff and students at Scottish universities concerning attitudes to the use of animals in education are reported. Discussed are survey methods used, the results of each survey, and bioethics in general. The staff and student questionnaires are both included. (CW)

Discussed are problems revealed in student responses to a practical task which formed part of an advanced level examination. The frequencies with which some misconceptions about cell reproduction and genetics occurred are presented. The nature of these misconceptions is analyzed and their implications discussed. (CW)

Describes the Tardigrada as a group of animals suitable for close study in project work. Gives reasons for their suitability and an illustrated identification key. Discusses possible investigations into the ecology and physiology of tardigrades. (Author/CW)

Described is a study of 147 students that indicated a high proportion of students did not understand the concept of limiting factors. Textbook presentations that create problems are discussed. Strategies which may be more effective in teaching the concept are suggested. (CW)

Investigated common belief patterns secondary school students (N=84) have about inheritance, noting the most prevalent misconceptions about genetics which occur at different age levels. Implications based on findings and suggestions for teaching lower secondary courses are included. (ML)

Discusses variables which determine the strategies animals use to organize their lives. Describes advances in understanding animal behaviors. Shows how game theory has helped to explain the existence of alternative behavioral strategies and the constraints under which organizers exist. (Author/CW)

Reports that story-type chapters with dialogues, presented to lower secondary pupils (N=546) before they read a bio-technical text: (1) increased their objective understanding in terms, bio-technical instruction, and sequences in a process; and (2) enhanced their subjective assessment of the ease and attractiveness of the bio-technical text. (DH)

Over 600 students taking advanced level biology in more than 130 schools were surveyed to investigate the relationship between their attitudes toward fieldwork and factors associated with fieldwork teaching. Responses given by the students and their teachers are presented and discussed. (Author/JN)

The advantages and justifications for using small animals in human-oriented research are reviewed. Some of the pitfalls of extrapolating animal-derived data to humans are discussed. Several specific problems with animal experimentation are highlighted. (CW)

Deals with the practical assessment of the General Certificate of Secondary Education (GCSE) in Great Britain with regard to the requirements set forth in biology syllabi. Addresses the requirements of the British National Criteria for assessment of experimental skills, the assessment framework, and the principle of positive achievement. (TW)

Investigated secondary-level students' (N=66) understanding of three-dimensional structures in biology. Results suggest that student performance is highly correlated with age, scientific ability, and sex. Suggestions for instructional improvement in spatial relationships are offered. (ML)

Examined the effectiveness of cooperative, competitive, and individualistic interaction patterns in promoting acquisition of science process skills during biology laboratory activities. Results (from 720 secondary students--352 girls and 368 boys) show that competitive interaction was superior to cooperative and individualistic interaction…

Investigated is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

The results of a study conducted with elementary school students in Tanzania are presented. A number of alternative conceptions were revealed. The role of sociocultural beliefs in forming these conceptions is described, and the implications of these findings for science teaching and teacher education are discussed. (Author/CW)
