Students success in science depends on: the degree of cultural difference that students perceive between their life-world and their science classroom; how effectively students move between their life-world culture and the culture of science or school science; and, the assistance students receive in making those transition easier (Costa, 1995; Jegede, 1995; Jegede & Aikenhead, 1999; Phelan, Davidson, & Cao, 1991). Aikenhead (2001) described that in the pursuit of cross cultural border crossing, students make their transition like a traveller, and some students experience some unfamiliar culture. Students thus require a degree of guidance from a travel-agent type of teacher who can provide incentives for them to travel smoothly into the culture of science. The incentives may include any scientific topic, scientific issues, events or scientific controversies. Providing incentives to students may create the need to know more about the culture of science (Aikenhead, 2001).
