Teacher educators and researchers have studied the improvement of teacher education programs so that pre-service teachers may be well prepared. Research has shown that not only teachers' knowledge but also their beliefs have major influence on their approach to teaching. This present research examined the mathematics and science pre-service…

We describe a simple, yet intellectually challenging model of grazing systems that introduces basic concepts in ecology and systems analysis. The practical is suitable for high-school and university curricula with a quantitative orientation, and requires only basic skills in mathematics and spreadsheet use. The model is based on Noy-Meir's (1975)…

Business students are typically introduced to the concept of process management in their introductory course on operations management. A very important learning outcome here is an appreciation that the management of processes is a key to the management of quality. Some of the related concepts are qualitative, such as strategic and behavioral…

This paper focuses on the cognitive processes that occur while students are exploring motion graphs. In a classroom experiment, we examine how high-school students (aged 17), with backgrounds in calculus and physics, interpret the graphs they create through drawing the path of the movement of their hand with a computer mouse. Based on recent, and…

Employing the 1988-1994 surveys from the National Education Longitudinal Study of 1988, we find that non- Hispanic white students with self-employed parents in managerial occupations scholastically underperformed after the eighth grade compared to their counterparts from salaried households with respect to mathematics and reading progress,…

School effectiveness research has fueled debate on the importance of a press for academic excellence versus communal values. Research on parenting styles offers a theoretical framework that may resolve the debate. We hypothesized that dimensions of parenting styles--demandingness (academic press) and responsiveness (communal values)--predict…

This case study of a preservice secondary mathematics teacher focuses on the teacher's beliefs about his role as mathematics teacher. Data were collected over the final 5 months of the teacher?s university teacher education program through interviews, written course assignments, and observations of student-teaching. Findings indicate that the…

This study presents a continuing investigation of influences on outcomes achieved by students working in groups of three on tasks related to chance and data. Earlier research described final mathematical outcomes and identified 17 factors influencing three types of short-term outcomes for groups working in an "isolated setting." The current report…

In a classroom, a teacher attempts to convey his or her knowledge to the students, and thus it is important for the teacher to obtain formative feedback about how well students are understanding the new material. By gaining insight into the students' understanding and possible misconceptions, the teacher will be able to adjust the teaching and to…

This paper is based on a long-term didactic engineering about division problems (only in a numerical setting) at primary school. Situations and students' work are analyzed by means of a double theoretical framework: the theory of situations and the theory of conceptual fields (Vergnaud 1991). The analysis focuses mainly on classroom interactions…

The purpose of this study was to explore how Year 8 students answered Third International Mathematics and Science Study (TIMSS) questions and whether the test questions represented the scientific understanding of these students. One hundred and seventy-seven students were tested using written test questions taken from the science test used in the…

This paper examines theoretical and empirical evidence related to primary teachers' subject knowledge in mathematics and considers the relevance of an audit of higher-level subject knowledge to the subject knowledge required for teaching primary mathematics. Questionnaires and interviews were carried out to determine the views of generalist…

What factors contribute to the acceptance of a new discipline? The disciplinary map is not static but not all candidate disciplines find acceptance in the academy. This article presents a case study of the acceptance of a discipline in one university. It argues that a close association with an existing high-status discipline was fundamental to the…

Urban schools across the United States face a pervasive problem in their science and mathematics programs-a disproportionate number of the teachers in these classrooms are not certified, thus making them underqualified to teach these subject areas. Furthermore, urban schools deal with teacher shortages and attrition in these critical areas. The…

This study proposed that precollege students' standardized mathematics achievement score and the congruence between their occupational interests and engineering tasks would predict their second-year retention in college and the stability of their major. Binary response models were used to predict second-year major status (i.e., continue, transfer…
