“…Many studies in the area of science education have indicated that problem‐solving‐based instruction or inquiry‐oriented instruction results in greater student achievement than the strategies reflected in traditional science classrooms (Henkel, 1968; Russell & Chiappetta, 1981; Mulopo & Fowler, 1987; Hall & McCurdy, 1990; Geban et al 1992; Chang & Barufaldi, 1999; Chang & Mao, 1999). There were relatively few studies, however, which tried to improve pupils’ science achievement through a problem‐solving‐based computer‐assisted tutorial within a classroom setting.…”
