Although approximately 5-8% of students have a mathematical learning disability (MLD), researchers have yet to develop a consensus operational definition. To examine how MLD has been identified and what mathematics topics have been explored, the authors conducted a systematic review of 165 studies on MLD published between 1974 and 2013. To move…

This article proposes an integrated theory of acquisition of knowledge about whole numbers and fractions. Although whole numbers and fractions differ in many ways that influence their development, an important commonality is the centrality of knowledge of numerical magnitudes in overall understanding. The present findings with 11- and 13-year-olds…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a crosssectional design. Results indicated that the difference…

The field of mathematics is complex, areas such as arithmetic, and geometry each consist of several sub-domains and encompass many cognitive processes. Achievement tests for elementary pupils assess a wide range of arithmetic skills such as number sense, procedural knowledge, and using problem solving strategies. Although mathematical tests often…

A survey test in mathematics (see TM 000 965) was administered to all pupils in Grade 7 of the Vancouver School System. Test content included arithmetic fundamentals, modern mathematical concepts and mathematical applications in problem solving. A summary of test results is presented in three tables. (CK)

This test was designed to cover the new seventh grade mathematics course (see TM 000 964) in the Vancouver schools. The 45-item multiple choice test designed to be completed within a 70 minute period stresses arithmetic fundamentals, modern mathematical concepts, and mathematical applications in problem solving.

This item bank was compiled by the Australian Council for Educational research (ACER) to help teachers at the secondary school level construct objective tests in arithmetic and algebra. The multiple-choice items were written by teachers who attended ACER writing workshops. The questions are classified according to their subject content and the…

Brief annotations of currently available basic learning tests, which were either specifically designed for adults or modified for use with adults, are presented. Information given for each measure includes author; the source from which it may be obtained; the purpose of the instrument; the nature of the materials; groups for which it is intended;…

A longitudinal evaluation of language arts and mathematics achievement for grades 5 to 8 in the St. Catharines, Ontario school system over a forty-year span is presented. The comparison is based on three different studies conducted from 1933 to 1938, from 1952 to 1954, and from 1975 to 1977. Secondary contributions--the effects of changes in…
