A prescriptive model of problem-solving performance is described. The aim of the model is to specify explicitly how problems should be described initially in such a form as to facilitate their subsequent solution. According to the model, the process of initial problem description can be decomposed into two successive stages. The first uses general…

This study examined a proposed procedure for constructing theoretical descriptions of mechanics problems, in particular, to determine if the procedure led to explicit and correct descriptions of the motion and interaction of systems and if the resulting theoretical descriptions facilitated generation of correct constraint equations and, hence,…

Interpersonal Process Recall (IPR) is a technique in which audiotapes are used to evoke students' memories concerning their own thinking. Reports a study using IPR to probe elementary students' (n=17) thinking during a problem-solving situation. Concluded that IPR has potential in classroom research. (MDH)

This paper illustrates the use of rule space as a tool to support cognitive analyses of students' mathematical behavior. The rule space approach is explained and is then used to classify students into one of two methods for solving linear algebraic equations in one unknown and to diagnose their knowledge states in this topic. A 32-item test with…

Discusses two methods for developing and assessing fluid abilities. In the first method, students are asked to solve increasingly unfamiliar problems in a domain; and in the second, students are required to organize knowledge in new ways or view it from different perspectives. (SLD)

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…

A broad range of research efforts are currently examining the quality and nature of the mathematics instructional program in the early grades. The purpose of this paper was to report on the assessment of a teaching-learning program in grade one classrooms. The major goals of the study were to: (1) identify patterns and change in children's…
