Discusses some ideas for applying information and communication technology (ICT) to constructing identification keys. Proposes the use of linked web pages as the most easily used and readily accessible for students aged 12-13. (DDR)

Explains the basics of chromatography which is used to demonstrate the separation of plant photosynthetic pigments. Reports the results of an evaluative study that explored textbook errors in explaining how chromatography works. (Contains 13 references.) (Author/YDS)

Recommends a number of investigations using video-capture and two readily available, non-pathogenic larval Digeneans with contrasting life cycles and behavior. The activities support the hypothesis that parasites exhibit behavior that increases their chances of a host infection. (DDR)

Describes an investigation into the photosynthetic potential of the different developmental stages of the green unicellular alga Haematococcus pluvialis. Reviews the biotechnological applications of astaxanthin, the red pigment which can be extracted from Haematococcus pluvialis. (Author/MM)

Procedural understanding should be taught to students for an understanding of the 'nature of science'. Considers some of the concepts of evidence that are particularly important to biology, and discusses how and why these ideas could be taught. (Contains 21 references.) (Author/YDS)

Discusses several new assessment strategies that encourage meaningful learning and conceptual understanding in biological science. Introduces evaluation and measurement techniques that help students assimilate well-integrated, strongly cohesive frameworks of interrelated concepts as a way of facilitating 'real understanding' of natural phenomena.…

Explores implications of the view that there is no such thing as the scientific method for biology education. Suggests fresh approaches to the teaching of drawing in biology, the teaching of classification, and the teaching of human biology by illustrating opportunities for investigating and describing the world scientifically. (Contains 32…

Summarizes the recent research on pollen germination and introduces some basic studies on pollen tube growth that can be conducted in a secondary school laboratory. Discusses the use of a light microscope and refrigerator to study pollen. (Contains 13 references.) (Author/YDS)

Presents a project for modeling cellular ultrastructure for 14-17 year old students that helps to develop concepts of measurement and scaling in addition to supporting student understanding of cell biology. (Author/YDS)
