Sex differences in performance of year-11 British students in science are being explored in an ongoing study. Some early results and tentative conclusions are reported. Double award science was introduced in England to improve scientific literacy, to reduce sex imbalances in later science pursuits by females, and to encourage generally greater…

The student variables associated with scoring above the international mean on the Third International Mathematics and Science Study (TIMSS) were studied in a group of U.S. students who took advanced mathematics or advanced mathematics and physics. The total sample was 2,349, with 1,158 females and 1,191 males. Formal parent education level and…

This report examines the potential of adaptive testing, two?-stage testing in particular, for improving the data quality of the National Assessment of Educational Progress (NAEP). Following a discussion of the rationale for adaptive testing in assessment and a review of previous studies of two-?stage testing, this report describes a 1993 Ohio…

Describes a test item bank developed by the Association for Medical School Departments of Biochemistry (Texas). Programs (written in Pascal) allow self-evaluation by interactive student access to questions randomly selected from a chosen category. Potential users of the system (having student, manager, and instructor modes) are invited to contact…

The old Medical College Admission Test (MCAT) and the New MCAT were compared by factor-analyzing the scores of a sample of 1,484 examinees who took both tests during 1976-77. Three common factors are interpreted: a general science quantitative factor, verbal ability, and interpretation skills. Variances are noted and implications of the data for…

The data suggest a pattern of overall improvement among students in the Southeast and notable improvements among Blacks in the Southeast in reading at ages 9 and 13 and in science at age 9. The article speculates on reasons for these improvements. (Author/IRT)

A simulated Medical College Admission Test (MCAT) was administered to 39 premedical students two weeks prior to the new MCAT. High correlations between simulated and active test scores were obtained in the biology, chemistry, physics, science problems, reading, and quantitative areas. (MH)

So far, results from the massive Third International Mathematics and Science Study indicate that American students have not yet achieved national goal number 5--to be first in the world in math and science achievement by 2000. Although fourth graders' results were surprisingly stronger than eighth graders' scores, American students' overall…

Whether differences in mean scores among gender and racial/ethnic groups on science performance assessments are comparable to those for traditional tests was studied with 2,000 students in grades five, six, and nine. Overall, results suggest that the type of test has little effect on these differences in scores. (SLD)

Investigated are the context dependency and construct validity of practical skill assessment in science which may include the skills of observing, manipulating, planning, interpreting, reporting, and self-reliance. Pupil performance on a variety of practical tasks were compared with external examination grades in biology and chemistry. (CW)

Presented is a criticism of the instructions given for and the scoring of the Draw-a-Scientist test (Chambers, 1983). A response to this criticism by authors who employ this method is included. (CW)

Described is a curriculum survey of general chemistry courses at the college level and an evaluation survey of the advanced placement chemistry examination. Results indicated that the AP chemistry course should remain broad in coverage and should expand its laboratory component. Analyses also indicated that the AP exam was appropriate and valid.…

Investigates Israeli students' (grades four through nine) knowledge regarding the concept of a "gas" prior to and following instruction. Reports that students do not spontaneously develop a general idea of gas prior to instruction, and only after instruction do they first acquire this knowledge. Suggests three implications for…

Describes an exercise designed for an introductory level calculus-based physics class. Presents a problem on why a rod dipped in water is stable when it is oriented at an angle with the vertical. Discusses qualitative understanding, mechanical understanding using equations, and experimental verification of the problem. (YP)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)
