Probability theory can be developed from a theoretical or experimental probability approach. The problem, "The Gambler's Ruin," is used to study whether students are naturally sensitive to learning probability from an experimental probability approach through simulations. Results indicated that use of simulations can contribute to…

The LOGO subroutine turtle geometry and Euclidean geometry are compared with respect to their treatment of similarity and difference of plane figures. The problem and its proposed solution of introducing a FLIP operation are viewed briefly from the perspectives of mathematics, computer science, and education. (MDH)

Presented are two activities that provide opportunity to review topics while integrating interests and developmental levels of middle and high school students. The first describes a take-off of the MTV game "Remote Control." The second, a problem-solving activity, organizes student movement from desk to desk, with students solving…

Counterintuitive moments in the classroom challenge common sense and practice and can be used to help mathematics students appreciate the need to explore, reflect, and reason. Proposed are four examples involving geometry, systems of equations, and matrices as counterintuitive instances. (MDH)

Presents a mathematical problem that, when examined and generalized, develops the relationships between power and efficiency in energy transfer. Offers four examples of simple electrical and mechanical systems to illustrate the principle that maximum power occurs at 50 percent efficiency. (MDH)

Presents a study to determine whether computer use in guided-discovery learning episodes would enhance the problem-solving ability of secondary school students (n=147). Results indicate interaction between low- and middle-level students' mathematical achievement and treatment groups, while high-level students performed well regardless of approach.…

The effects on college students' (n=110) attitudes of using a microcomputer as a demonstration aid was investigated in an intermediate algebra class. Results suggest a significant treatment effect on students' attitude favoring the microcomputer treatment group. (16 references) (MDH)

An ethnographic approach with added quantitative and qualitative data collection and analysis was used to study the extent and nature of technology-based materials in 15 elementary school mathematics classrooms. The blend of methods provided rich and varied information and gave insights either type of analysis could not provide alone. (SLD)

Discusses potential changes in professional development programs that can lead to the establishment of new environments in mathematics classes. Proposes changes that promote reflective practice, mathematical inquiry by teachers, and participation in a mathematics community. (MDH)

Discusses mathematical tasks, classroom environments, and means of assessment that might encourage mathematical growth for middle grades students. Proposes a curriculum emphasizing mathematical connections, reasoning, and problem solving. Describes shifts in the culture of the mathematics classroom that support students' development of…

Kindergarten students' (n=7) thought processes were investigated during a problem-solving task to gain insight into students' problem-solving strategies and to guide students toward a closer awareness of their own mathematical thinking. Outlines some of the processes and problems of implementing a constructivist approach by an experienced teacher.…

Examined the quality of responses of six classes of grade six students to four questions requiring multiple and generalized solutions posed under varying conditions. Results indicated that this type of question can be useful in classrooms because students can respond at a variety of levels. (13 references) (MDH)

Proposes sharing mathematics-related newspaper stories as a classroom method to illustrate the importance and relevance of mathematics in the students' lives. Provides examples of appropriate stories and ways they can be used in the classroom. (18 references) (MDH)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)

Discusses the process of mathematical iteration, its benefits as a problem-solving technique, and how to teach it. Presents a selection of mathematical ideas and problems that can be solved and explored using iteration, along with related BASIC computer programs. (MDH)
