Maitland, Pamela D.; Maitland, David P. – Journal of Biological Education, 2002
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)
Descriptors: Biology, Chemical Analysis, Chromatography, Higher Education
Peer reviewed Peer reviewed
Smith, Mark – Journal of Biological Education, 2002
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)
Descriptors: Biology, Classification, Communications, Computer Uses in Education
Peer reviewed Peer reviewed
Roberts, Ros – Journal of Biological Education, 2001
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)
Descriptors: Biology, Cognitive Development, Curriculum Development, Higher Education
Peer reviewed Peer reviewed
Mintzes, Joel J.; Wandersee, James H.; Novak, Joseph D. – Journal of Biological Education, 2001
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.…

Reiss, Michael J.; Tunnicliffe, Sue Dale – Journal of Biological Education, 2001
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…

Tse, H. L. H.; Chan, G. Y. S. – Journal of Biological Education, 2001
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)
Descriptors: Biology, Botany, Laboratory Experiments, Reproduction (Biology)
Peer reviewed Peer reviewed
Bushell, Jean – Journal of Biological Education, 2001
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)
Descriptors: Biology, Concept Formation, Cytology, Models
Peer reviewed Peer reviewed
Rea, J. G.; Irwin, S. W. B. – Journal of Biological Education, 2001
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)
Descriptors: Biology, Computer Uses in Education, Educational Strategies, Elementary Secondary Education
Peer reviewed Peer reviewed
Delpech, Roger – Journal of Biological Education, 2001
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)
Descriptors: Biology, Chromatography, Experiential Learning, High Schools
Peer reviewed Peer reviewed
Jones, Alick R. – Journal of Biological Education, 1980
Describes methods for collection, culture, observation, and making permanent stained preparations of the protozoan vorticella. Suggestions are made for experiments to investigate growth, reproduction, settlement, ecology, feeding, and osmoregulation. (CS)
Descriptors: Animals, Biology, College Science, Higher Education
Peer reviewed Peer reviewed
Murray, Philip J.; Bristow, Andrew W. – Journal of Biological Education, 1997
Presents a simple method of recording root growth which can be used in schools. A slant board system was designed to facilitate access to roots to enable measurements to be made, essentially forcing the roots to grow in a two-dimensional form which allows each student to observe and record root growth over several weeks. (AIM)

Lutterschmidt, William I.; Schaefer, Jacob F. – Journal of Biological Education, 1997
Discusses a computer simulation designed as an educational tool for students to observe predator-prey oscillations and experimentally investigate how changes in life histories affect predator and prey densities. Provides hands-on interaction with such theories and with mathematical models. Available to any instructor for curriculum use. (AIM)
Descriptors: Biology, Computer Oriented Programs, Computer Simulation, Computer Uses in Education
Peer reviewed Peer reviewed
Yip, Din Yan – Journal of Biological Education, 1997
Presents two simple and reliable ways for measuring protease activity that can be used for a variety of investigations in a range of biology class levels. The investigations use protease from a variety of sources. (DDR)
Descriptors: Biology, Chemical Reactions, Enzymes, Higher Education
Peer reviewed Peer reviewed
Newton, Leonard R. – Journal of Biological Education, 1997
Considers the place of information technology in biological education and addresses some of the obstacles to its greater use as well as potential benefits. Offers a rationale which asserts the role of the teacher as the architect of learning experiences. Contains 25 references. (DDR)
Descriptors: Biology, Computer Uses in Education, Cytology, Educational Technology
Peer reviewed Peer reviewed
Bozzone, Donna M. – Journal of Biological Education, 1997
Describes an experimental project that uses plant tissue culture techniques to examine cell differentiation in the carrot. Allows students to gain experience in some important techniques and to explore fundamental questions about cell differentiation. (DDR)
