This study examined elementary school children's beliefs about learning and assessed the influences of such beliefs on their understanding of science texts. Eighty-three children, 46 from Grade 4 and 37 from Grade 6, were administered a questionnaire on children's implicit notions of learning. Children were also asked to read a science text and complete several tasks that assessed their understanding of text information. Results indicated that older children were more likely to hold constructivist views of learning, and they also performed better than younger children on the text-processing tasks. As well, children's views of learning were significantly related to depth of text understanding when age effects were controlled. This study extends current research on epistemological beliefs of university and high school students. Implications of children's beliefs about learning and their roles in knowledge construction are discussed. Copyright 2001 Academic Press.
