Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

Investigated the relationships of figural response items and open-ended verbal items in biology to figural and verbal mental aptitudes (n=24). Performance on the verbal items was positively related to verbal ability. Figural response scores were related positively to both figural and verbal abilities. (PR)

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

Certain that students' average standardized test scores did not reflect their faculty's teaching effectiveness, Department of Defense dependent schools in Wuerzburg, Germany, mounted a districtwide experiment involving performance tests and rubrics in writing and science. Teachers documented gains in students' high-level writing and science skill…

Examined the effect sizes associated with mean differences in performance on the Second International Assessment of Educational Progress (IAEP2) and the Third International Mathematics and Science Study (TIMSS) administered in 1995. Largest differences were associated with the performance of students in France, Ireland, and Switzerland. Proposes…

Argues that test score rankings provide little information about educational quality because countries differ substantially in factors such as student selectivity, curriculum emphasis, and the proportion of low-income students in the test-taking population. (DDR)

Studied the effects of test consequences, response formats, gender, and ethnicity on the mathematics and science sections of the Michigan High School Proficiency Test. Results for more than 11,000 students show that students taking constructed response and multiple choice formats performed better under high stakes conditions. Discusses gender and…

In this article, we report on an experiment designed to improve the learning of metabolic biochemistry by nutrition and medical undergraduate students. Twelve students participated in a monitored lunch and had their blood extracted for analysis: (1) before lunch; (2) 30 min after lunch; and (3) 3 h after lunch. The subjects were divided in two…

This study investigates whether or not (a) 252 Jamaican high school students (168 boys, 84 girls, 171 grade 10 and 81 grade 11 students) had favourable attitudes to biology, (b) their level of biology performance was satisfactory, (c) there were significant differences in their performance based on their gender, grade level, school-type,…

This study sought to find out if (a) the performance of 113 Jamaican 11th-graders on a mole concept test was satisfactory or not; (b) there were significant differences in their performance linked to their chemical and mathematical abilities, gender and socioeconomic background (SEB); and, (c) there were significant relationships among the four…

Diminishing "standards" and "alignment" to overused buzzwords or superficial checklists masks the dire need for truly systematic and operational standards-based alignment in science education. In this article, the authors report the findings of an ongoing collaborative effort between cognitive researchers and urban science…

Scientific literacy is the ultimate goal in science education world-wide; especially in this modern society of science and technology. How to help individuals to make good judgments and promote their skills of argumentation becomes an important issue. Meanwhile, in the Information Age, visual image is an important medium for conveying information.…

One component of the Maryland School Performance Program (MSPAP) is the state's performance-based assessments, criterion-referenced tests that require students to apply what they know and can do to solve problems and display other higher-order thinking skills. This document helps parents, teachers, students, and other citizens understand the tasks…
