“…Also of importance is to heighten the level of interactivity available in course elements that have a highly practical nature, such as computer programming or experimental work. This is not as infeasible as it might sound: simulation tools can be of great benefit in such areas ( Alder et al ., 1990 ; Svanaes, 1990; Anderson & Jackson, 1995a; Watkins et al ., 1995 ; Livesey, 1997), and some research has been done on problem‐based learning support ( Anderson & Jackson, 1995b).…”
