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)

Discusses issues related to examination questions which begin by asking students to "Describe an experiment to..." Indicates that this strategy is useful when focusing on important quantities/phenomena or "celebrated" experiments and that examining boards should not request students to describe experiments which verify or…

Surveys the trait anxiety profile and preference concerning types of examinations of preservice science teachers. Reports that the students prefer examinations on understanding and analyzing rather than on knowing and remembering, and that students' anxiety states correlate with the type of examination and sex.

Students' justifications for the three-item formats provided were compared. The study confirmed the usefulness of justifications as a diagnostic tool and offered recommendations regarding the use of justifications, including their use in the construction of two-tier items. (Author/CW)

Indicates that the language in which a multiple-choice question is couched may be a significant factor in student performance. Effects of changing key words, terms of quantity, negative to positive forms, and from passive to active voice are discussed. Also discusses the effect of rewording long or complex questions. (JN)

This manual informs tutors/evaluators and students about the Caribbean Examinations Council's (CXC) school based assessment (SBA) of integrated science skills. It includes directions for the teacher/evaluator and a student activity package. The SBA is done in agricultural science, biology, chemistry, integrated science, and social studies and is…

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…

Outlines a procedure used to develop a written diagnostic instrument to identify misconceptions and misunderstandings of the chemistry topic. Reports the characteristic data for the instrument, and student understanding of covalent bonding and structure. (Author/YP)

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…

Contains two articles relating to chemistry examination questions. One provides examples of how to sequence multiple choice questions so that partial credit may be given for some responses. The second includes a question and solution dealing with stereoisomerism as a result of free radical chlorination of a nonstereoisometic substance. (TW)

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…

Analyzes an old chemistry examination that was given to a college chemistry class in 1984. Contrasts several of the examination's features against most modern ones. Notes the emphasis on observable properties and the practical applications of substances. Argues that the newer examinations may stress too much theory and don't stress communication…

The Louisiana Educational Assessment Program (LEAP) Grade 11 Test is designed to measure proficiency in four subject areas including English, mathematics, social studies, and science. This guide for science is intended to provide a description of the way in which specific skill areas are assessed on the LEAP test and instructional considerations…

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);…

Promotes the use of machine-scored tests in basic engineering science classes. Discusses some principles and practices of machine-scored testing. Provides several example test items. Argues that such tests can be used to enhance basic understanding of concepts and problem solving skills. (TW)
