Children trained in the clustering-operations approach showed greater achievement than those trained in a traditional approach. The clustering approach presents all four operations simultaneously. (MP)

Compares student performance on fraction/number line tasks which varied length and equivalence. Associating proper fractions was easier on number lines of length one rather than length two; and where number of equivalent line segments in each unit segment was the same as the denominator, rather than twice that number. (CS)

This study looked at student difficulties with fractions by focusing on understanding of part/whole relationships. The sample consisted of two sixth-grade and two eighth-grade classes. A lack of substantial improvement from sixth to eighth grade on many fraction tasks was noted and viewed as cause for concern. (MP)

Examined is the effectiveness of a computer software package designed to be consistent with a fraction strip chart model. The materials are described; they were used with three fourth-grade classes, while two other classes acted as controls. (MNS)
