The aspect of the Unified Science and Mathematics for Elementary Schools (USMES) project described in this paper was undertaken in an effort to observe the problem solving behaviors of elementary school children. The Notebook Problem consisted of presenting a student with three notebooks arranged so as to differ from each other in terms of such…

Reported is a study on the problem-solving skills of sixth-grade students. Three curricula were utilized in the study: Science - A Process Approach (SAPA), the Laidlaw textbook series, and the Environmental Studies (ES) Project materials. Twenty-seven teachers in eight schools participated. Each of the teachers taught one of the three curricula.…

The purpose of this study was to prepare a valid and reliable instrument to evaluate the objectives dealing with the behaviors expected in Part 1 of the Physical Science Study Committee (PSSC) physics course. There were six phases to the study: (1) identification of the processes, (2) selection thereof, (3) construction of instrument, (4) pilot…

Four types of proportionality problems were administered to: (1) secondary school students who were enrolled in Project Physics, and (2) students not enrolled in physics. Both samples were randomly selected. Groups were not found to differ significantly in problem solving ability but both revealed that the ability to solve certain problems was…
