Attempts at integrating mathematics and science have been made previously but no definitive, widely adopted teaching model has been developed to date. Research suggests that hands-on, practical, student-centred tasks should form a central element when designing an effective model for the integration of mathematics and science. Aided by this…

The results presented here derive from a longitudinal study of Swedish upper secondary science students' (16-19 years of age) developing understanding of key chemical concepts. The informants were 18 students from two different schools. The aim of the present study was to investigate the mental models of matter at the particulate level that…

With this new technology there are also many safety and ethical questions, though, as well as the need for education. Alternative teaching methods may help to increase students' understanding of difficult concepts in all aspects of schooling, including…

Uses simple models to illustrate the principles of this genetic method of mapping gene loci. Stresses that this system enables a practical approach to be used with students who experience difficulty in understanding the concepts involved. (CW)
