Sex differences in intrinsic aptitude for mathematics and science?: a critical review.

American Psychologist, 2005
This article considers 3 claims that cognitive sex differences account for the differential representation of men and women in high-level careers in mathematics and science: (a) males are more focused on objects from the beginning of life and therefore ...

Variables in Elementary Mathematics Education

The Elementary School Journal, 2016
AbstractIn this article, I analyze episodes from two third-grade classrooms drawn from a larger classroom teaching experiment to explore how these students began to incorporate nonnumerical symbols in their mathematical expressions when asked to represent indeterminate quantities.

A Mathematical Type for Physical Variables [PDF]

, 2008
In identifying the requirements of a markup language for describing the mathematical semantics of physics-based models, we pose the question: "Is there a mathematical type for physical variables?" While this question has no a priori answer, since physics is fundamentally empirical, it appears that a large body of physics may be described with a single ...

ON VARIABLES IN MATHEMATICS AND IN NATURAL SCIENCE

The British Journal for the Philosophy of Science, 1954
IN the development of mathematics and natural science which began in the seventeenth century, perhaps the most characteristic concept is that of a variable. But what is a variable ? Russell, who investigated all aspects of this notion, called it 'certainly ...

Affective Variables and Mathematics Education

The Elementary School Journal, 1984
to general feelings such as liking/disliking of mathematics, nor is it meant to exclude perceptions of the difficulty, usefulness, and appropriateness of mathematics as a school subject. There are several ways affective variables are related to mathematics learning. It is likely that a student who feels very positive about mathematics will achieve at a

GIRLS AND MATHEMATICS: PARENTAL VARIABLES

British Journal of Educational Psychology, 1979
Summary. 234 girls taking A‐level mathematics were compared with 265 girls taking A‐level French. They were more reserved (A), stable (C), tough‐minded (I), radical (Q1) and group‐dependent (Q2) on the 16PF, and less feminine on the CPI Fe Scale. Girls in both subjects tended to identify with their fathers rather than mothers. Father identification is

Role of self-efficacy and self-concept beliefs in mathematical problem solving: A path analysis.

, 1994
Path analysis was used to test the predictive and mediational role of self-efficacy beliefs in mathematical problem solving. Results revealed that math self-efficacy was more predictive of problem solving than was math self-concept, perceived usefulness ...
