Abstract
This paper reports on an ongoing study of errors in the use of fractions exhibited by a
sample of 396 Primary 5 pupils in Brunei Darussalam. Among the five types of errors
identified, those demonstrating a lack of understanding of basic facts predominated. The
quantitative data reported here were obtained from a diagnostic pre-test administered in a
longitudinal study. The test was administered during the first phase of the study, and
coupled with qualitative data obtained from pupil interviews. After having identified the
different errors exhibited by the pupils, the study set out to investigate in which
components of the fractions syllabus significant errors occurred. Data from the pre-test was
shared with the 15 teachers whose pupils participated in this study in order to assist the
subsequent teaching of fractions. The presentation will include a discussion of possible
reasons for the identified errors.
