Misconceptions about density of decimals : insights from Indonesian pre-service teachers’ work
Widjaja, Wanty, Stacey, Kaye and Steinle, Vicki 2008, Misconceptions about density of decimals : insights from Indonesian pre-service teachers’ work, Journal for science and mathematics education in Southeast Asia, vol. 31, no. 2, pp. 117-131.
Extensive studies have documented various difficulties with, and misconceptions about, decimal numeration across different levels of education. This paper reports on pre-service teachers’ misconceptions about the density of decimals. Written test data from 140 Indonesian pre-service teachers, observation of group and classroom discussions provided evidence of pre-service teachers’ difficulties in grasping the density notion of decimals. This research was situated in a teacher education university in Yogyakarta, Indonesia. Incorrect analogies resulting from over generalization of knowledge about whole numbers and fractions were identified. Teaching ideas to resolve these difficulties and challenges in resolving pre-service teachers’ misconceptions are discussed. Evidence from this research indicates that it is possible to remove misconceptions about density of decimals.
