Two tests were administered to 652 students to investigate the effect of structuring questions about the mole. A third test was administered to see whether each step/operation was intrinsically difficult or if it was only difficult when part of a series of steps/operations. Findings are reported and discussed. (JN)

Reports that no significant difference in reliability appeared between a heterogeneous and a homogeneous form of the same general science matching-item test administered to 316 sixth-grade students but that scores on the heterogeneous form of the test were higher, independent of the examinee's sex or intelligence.

Increased emphasis on public school accountability has resulted in several states including a science component in their elementary and middle school testing program. This component often includes items designed to measure process skill ability. The purpose of this study was to examine the performance of high school students on four types of…

This study investigated the relationships among the symbolic representation of problems given to students to solve, the mental representations they use to solve the problems, and the accuracy of their solutions. Twenty eleventh-grade science students were asked to think aloud as they solved problems on the ideal gas laws. The problems were…

Explores the concept of construct validity in the context of a public examination. Multitrait-multimethod analysis and factor analysis were used. Discusses the analyses in terms of theory versus practical components and experimental versus observational investigation in practical components. Sample items for the practical examinations are…

Information is presented about the grade 12 diploma examinations for Mathematics 30, Biology 30, Chemistry 30, and Physics 30 to be administered in 1988. Included are both the French and English language versions of the document. Topics explained include: (1) general format of the examinations (stating the content, emphasis, and time allotments);…

Information is presented about the grade 12 diploma examinations for Mathematics 30, Biology 30, Chemistry 30, and Physics 30 that were administered in 1986. Topics explained include: (1) general format of the examinations (stating the content, emphasis, and time allotments); (2) examination schedules (listing the calendar dates and times for the…

Reports on a study designed to determine whether or not biology students were being disadvantaged by taking computer tests instead of written paper forms of the same tests. Results indicated that mean scores on computer-administered and written forms of the same test were approximately equivalent. (TW)

The purpose of this project was to construct a valid and reliable noncurriculum specific measure of integrated science process skills intended for use with middle school students. The major efforts in test development were focused on the refinements and modifications of the set of objectives and test items assessed by the existing Middle Grades…
