Findings from physics education research strongly point to the critical need for teachers' use of multiple representations in their instructional practices such as pictures, diagrams, written explanations, and mathematical expressions to enhance students' problem-solving ability. In this study, we explored use of problem-solving tasks for…

A mathematics problem is presented and solved which concerns determining the approximate speed of an automobile involved in an accident. Extensions of the problem are suggested. (DT)

Examines the relationship of the amount of available short-term memory with the complexity of tasks the subjects mastered. Presents some hints for a better design of instruction. (YP)

Examines the mathematical process used by students when solving physics tasks that require proportional reasoning. Investigates students' understandings and explanations of their mathematical processes. (Author/CCM)

Discusses potential pedagogical difficulties arising from using physics-related contexts in high-school mathematics problems. Suggests that such problems should not require any external knowledge of physics by the students; meanwhile, the problems should not contradict the physics knowledge that the students may already have. Presents several…

The present research study investigates how undergraduate students in an integrated calculus and physics class use physics to help them solve calculus problems. Using Zandieh's (2000) framework for analyzing student understanding of derivative as a starting point, this study adds detail to her "paradigmatic physical" context and begins to address…

Describes an instructional method in secondary school mathematics applicable to physics instruction, to develop conceptual understanding of motion word problems. Distance, rate, and time are defined, used as variables and considered with relative motion as a unifying concept. (JM)

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Problems ask students to calculate the pressure against a billboard in high winds and the velocity of water flowing from a reservoir through a cylindrical pipe. Problem solutions incorporate computer tools such as spreadsheets. (MDH)
