Previous research concerning the cognitive abilities of high school students has indicated that a substantial number of students enrolled in secondary science courses do not conceptualize at the formal-operational level. Further, results indicate that achievement levels in chemistry coursework are significantly affected by, not only cognitive…

The aim of this study was to incorporate a web-assisted program to normal traditional classroom instruction and study about students' misconceptions in force and motion concepts in physics. The Web-based physics program was incorporated with the traditional lecture. Specifically, 30% of class time was allocated for using this tutorial program, and…

Data drawn from 30 journal articles and ERIC documents reporting on gender differences in natural science achievement were re-examined. Three meta-analysis methods were used: (1) vote counts and vote-counting estimation procedures; (2) tests of combined significance; and (3) analyses of effect sizes. The three methods produced seemingly…

Positive self-concept and good understanding of science are important indicators of scientific literacy endorsed by professional organizations. The existing research literature suggests that these two indicators are reciprocally related and mutually reinforcing. Generalization of the reciprocal model demands empirical studies in different…

This document contains four issues of "NAEPfacts," a report series about the National Assessment of Educational Progress (NAEP). Issue 1 discusses data from the NAEP 1996 Long-Term Reading Assessment, which shows that overall student reading performance has increased for both 9- and 13-year-olds. Issue 2 reports that data from the NAEP…

This sampler of student responses to mathematics and science items was assembled to show how student responses differ depending on whether students are tested in English or in their native languages. The sampler aims to promote awareness among teachers and assessment developers that low language proficiency in English is a factor that can penalize…

A study undertaken in Western Australia, the Western Australian School Effectiveness Study, explored the characteristics of effective high schools by investigating factors influencing science and mathematics achievement. A multilevel analytical model was used in the longitudinal study that focused on 1,024 students in 21 rural and urban high…

Cognizant of the American high school students' waning test scores and a decreased desire to pursue higher level courses in mathematics and science, there has been a categorical effort to identify the demographic and motivational variables that contribute to mathematics and science achievement. This study utilized the 1992 panel members (8,140…

In 1992 the American Association of University Women Educational Foundation (AAUW) Educational Foundation published "How Schools Shortchange Girls," a landmark report providing overwhelming evidence that girls were often ignored in the classroom and neglected in the curriculum. This report brought gender equity to the forefront of…

To explore the effects that changing to performance-based assessment has had on sex differences in science achievement that had been observed with traditional tests, 3 studies involving more than 906 elementary school students compared scores of males and females on performance-based tests. Few gender differences were found. (SLD)

In the mid-1980s, data were collected on international science achievement as part of the Second International Association for the Evaluation of Educational Achievement Science Study. The seven articles of this collection report on various facets of the practical skills testing of this study in which six countries participated. (SLD)

Student achievement, attitude, and instructional efficiency were determined for hands-on and for live and videotape demonstration laboratories for nonscience majors. Each of 3 laboratory sections experienced 3 different teaching methods for one 4-wk unit. No significant difference in achievement was found among the laboratory methods. An attitude…

This project explores the effectiveness of learner-centered education (LCE) principles and practices on student learning and attitudes in an online interactive introductory astronomy course for non-science majors by comparing a high-quality Internet-delivered course with a high-quality on-campus course, both of which are based on the principles of…

In this study, instructional activities in science classrooms are examined in order to collect evidence to account for the strengths and weaknesses of Hong Kong students in scientific literacy as reported in the PISA 2000 project. The study consists of a questionnaire survey on the perceptions of classroom climate of science lessons of 17,616…

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration…
