Further evidence of conceptual difficulties with decimal notation
Abstract: Over 3000 students in Grades 4 to 10 completed about 10000 tests to identify and track their conceptions about decimal notation. This paper reports the incidence of two particular errorpatterns on these tests and how this incidence changes over time, from crosssectional and longitudinal viewpoints. At some time, approximately 3% of students answered almost all test items incorrectly and over 10% were unable to compare decimal numbers with the same tenths and hundredths digits. Explanations for these errorpatterns are given.
