The structure of mental activity and the consequent development of its components functionally affect the quality of the students' performance. The aim of this research was to know the difference between some structural details of the psychological levels of the functionality of the students with and without learning difficulties. It is a…

In this study, we explore four, second graders' performances on integer addition problems before and after analyzing contrasting cases involving integers. The students, as part of a larger study, participated in a pretest, small group sessions, one short whole-class lesson on integer addition, and a posttest. Based on their integer mental models…

This book contains a compilation of papers presented at the International Conference on Education and New Developments (END 2017), organized by the World Institute for Advanced Research and Science (W.I.A.R.S.). Education, in our contemporary world, is a right since we are born. Every experience has a formative effect on the constitution of the…

Describes two studies that analyzed the impact of problem type on the understanding of commutativity of multiplication of (n=20) children ages 8-10. The concept seemed poorly understood, but the children did significantly better in the context of rotation than of rearrangement of elements. (Author/MKR)

This paper outlines a theoretical perspective for studying student understandings of the concept of addition. The notion of operational sense is defined as a way to describe the notion of addition as a mathematical object, paving the way for an application of the theory of reification at this level. Previous frameworks relative to problem solving…

Suggests study by Kuhn and others (PS 524 345) is too ambitious and that the processes described are not wholly representative of developmental stages. Argues the methodology of study was progressive problem solving, and that experimenter's questions resulted in contrived stages. (JW)

Presents a psycholinguistic analysis of the development of writing skills and reports a developmental study of knowledge effects in writing. A theoretical framework decomposes the requisite knowledge into three main components: (1) generalized, high-level problem-solving plans, (2) content, and (3) discourse. (Author/SED)

In general, studies investigating sex differences in mathematics performance have empirically analyzed students' responses from standardized tests. This paper reports a study to extend the investigation of sex differences related to mathematics performance by examining cognitive and motivational factors as well as standardized test scores. Boys…

Reports results from a project designed to bring about student conceptual change by using multiple modeling and representation as well as links to other areas. Students developed rules as conveniences and meanings for symbols, were active in learning, made interpretations, and had confidence in their thinking. (MKR)
