Despite the importance of computational estimation skill for the improvement of number sense, little research exists on preservice teachers' estimation skills and their view on estimation in the US context. This study examined the computational estimation skill of 58 preservice elementary teachers (PSTs) and its relationship to their views of the…

Evaluates the effectiveness of the supplementary use of two types of calculators with third-grade students. Compares acquisition and retention of mathematical skills, as well as student attitudes toward mathematics, hand-held calculators, programed feedback calculators and receiving instruction through the traditional approach. (Author/DS)

Research reviewed indicated calculator use: (a) significantly improves computational ability with conflicting evidence in other areas; (b) has no significant effects on retention or attitudes towards mathematics; and (c) does help in teaching and learning at all levels with no detrimental effect. Conclusions were drawn in part from examination of…

Investigated was the effect of availability of calculators, calculator-related curriculum resources, consultant resources, and inservice workshops on children's attitudes and achievement in mathematics (grades 2-6). Results indicated no measurable detrimental effects for calculator use. Significant gains on basic facts and achievement were made…

Investigated the long-term influence of a longitudinal calculator awareness approach to numbers on British elementary students' mathematical achievements and attitudes. Teacher and student interviews and student test scores from intervention and nonintervention schools indicated that the curriculum had no substantial long-term influence on…

The purpose of this study was to compare the achievement, attitudes, and teaching/learning experiences in mathematics programs of two groups of elementary-school students in grades 5 and 6. Approximately 150 students in each of two elementary schools were given as a pretest a standardized mathematics achievement test and a questionnaire regarding…

The purpose of this project was to develop and field test supplementary mathematics curriculum materials that could be used in a typical school setting to introduce elementary school children to calculators and computers in the process of solving everyday mathematical problems. The materials were designed to help teachers: (1) familiarize children…

The National Council of Teachers of Mathematics encourages the use of calculators in the classroom as a teaching and learning tool, as well as a computational tool. This paper evaluates the impact on teachers' approaches to teaching mathematics and students' attitudes toward mathematics as the result of participation in an in-service program…
