Using systematically colored circles to represent the elements, students are guided to a discovery of the important factor that leads to the periodic system. (DDR)

This model is useful in identifying specific learning problems and in providing techniques for the teacher to motivate and teach students at all levels. What it is and how it can be used are discussed, illustrated by specific strategies for geometry and science. (MNS)

Describes some problems of classroom dissection including the cruelty that animals destined for the laboratory suffer. Discusses the multilevel approach that the National Anti-Vivisection Society (NAVS) has developed to address the problems of animal dissection such as offering a dissection hotline, exhibiting at science teacher conferences, and…

Described is a Monte-Carlo method for modeling physical systems with a computer. Also discussed are ways to incorporate Monte-Carlo simulation techniques for introductory science and mathematics teaching and also for enriching computer and simulation courses. (RH)

The British National Curriculum calls for children to work with living things. Discusses alternatives available for teaching children about bugs, most notably through models and live animals kept in school. Models prove valuable for introducing children to bugs and for stimulating them to ask scientific questions. Raises issues behind keeping live…

Explores how changing curriculum and teaching techniques may lead to different composition of pool of scientists who hold slightly modified theoretical perspective. Presents seven-stage spiral model for transforming mathematics and science teaching, in which each stage fuels change in next stage, moving toward more accessible, varied, and humane…
