Even in simple mathematical situations, there is an array of different mathematical features that students can attend to or notice. What students notice mathematically has consequences for their subsequent reasoning. By adapting work from both cognitive science and applied linguistics anthropology, we present a focusing framework, which treats…

This paper describes changes which took place in 37 Hong Kong primary schools where class sizes were reduced from 38 to between 20 and 25. Chinese, English and mathematics classes were observed over three years from Primary 1 (aged 6) to Primary 3. For 75% of observations no child was the focus of the teacher's attention in large classes. Reducing…

An issue for many mathematics departments is the success rate of precalculus students. In an effort to increase the success rate, this quantitative study investigated how class size and teaching approach influenced student achievement and students' attitudes towards learning mathematics. Students' achievement and their attitudes toward learning…

Estimated the impact of class size on instructional practices and the use of time in high school mathematics and science courses using data from the National Education Longitudinal Study. Findings reveal that class size has an impact on the use of class time, both instructional and noninstructional. (SLD)

The comparative effects of large and traditional-sized remedial mathematics classes on college student aptitude and attitude were studied. Two large pre-algebra classes of 129 and 121 students and traditional-sized classes ranging in size from 30 to 40 students were assessed by informal observations and two instruments: a department-developed…
