For example, the researchers measured the students’ belief in the stability and structure of scientific knowledge by gauging their agreement with statements like: “Physics textbooks present theories that have been confirmed by scientists and are not going to change.”
Next, the ten per cent of the students with the most sophisticated beliefs about knowledge, and the ten per cent with the least sophisticated beliefs, answered questions on Newton’s three laws of motion.
Those students with sophisticated beliefs about scientific knowledge, who recognised that knowledge is changing and constantly reorganised, were significantly more likely to show an understanding of Newton’s laws of motion, than were the students whose epistemological beliefs were less sophisticated. By contrast, the students’ past school grades in physics did not predict whether they would understand Newton’s laws.
Not all students with more sophisticated epistemological beliefs showed a deep understanding of Newton’s laws, but none of the students with less sophisticated beliefs did. That is, in this study, sophisticated epistemological beliefs were necessary but not sufficient for a deep understanding of Newton’s laws.
“If we are interested in designing effective learning environments it is important to pay more attention to students’ epistemological beliefs and to develop curricula and instruction explicitly designed to promote epistemological sophistication,” the researchers said.
