Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while…

This study examined the effect of a computer-enhanced problem-based learning (PBL) environment on middle school students' learning, investigating the relationship among students' self-efficacy, attitude toward science, and achievement. As Bandura defined it (1986), self-efficacy refers to the beliefs people have about whether or not they can…

Data in this article were compiled from a number of sources by the U. S. Department of Education's National Center for Education Statistics (NCES). Categories covered include: elementary enrollment, pre-primary enrollment, parent and family involvement, international comparisons of fourth and eighth graders' performance in mathematics and science,…

When planning to teach science to students who are English language learners (ELLs), science teachers and some science educators look to sheltered instruction as a potential guide. The possibility of blending inquiry-based teaching with a sheltered instruction framework seems a promising method for providing high-quality science learning…

This publication is the 13th edition of the "Mini-Digest of Education Statistics," a pocket-sized compilation of statistical information covering the broad field of American education from kindergarten through graduate school. The "Mini-Digest" is designed as an easy reference for materials found in much greater detail in the…

The purpose of this study is to investigate science achievement of Australian students and how this achievement can vary from school to school. The proposition that gender and socioeconomic inequities in Australia are the result of school systems designed to reproduce an unequal social order is be examined with reference both to current…

Abstracts of most of the papers, symposia, discussion groups, round tables, and poster sessions presented at the 64th conference of the National Association for Research in Science Teaching (NARST) are provided. Subject areas addressed are as follows: teacher knowledge, cognitive development, conceptual change, curriculum issues, reform in science…

As part of a series of documents describing assessment of student learning in various curriculum areas in South Carolina, this document reviews the assessment of student learning in the science classroom. The report begins with a discussion of effective science learning, and outlines the knowledge, skills, and dispositions that encompass science…

This document discusses barriers that impede the progress and participation of Hispanic American students in mathematics and science education, and recommends extensive educational reforms. Following an introduction, the first of two main sections reviews the current Hispanic American underrepresentation in mathematics and science and describes…

This report, the second of two published to date, provides the most current information on progress made toward realizing the six national education goals adopted by the nation's governors and President Bush at an educational summit held in Charlottesville, Virginia, in 1989. The goals established a framework for action in terms of readiness for…

The relatively large number of students who perform poorly in freshman chemistry courses signals the need for the identification of criteria that will result in correct placement decisions for incoming college students. Research findings have generally reported placement criteria that correlate significantly with performance in college chemistry…

This study, using a non-experimental, exploratory and descriptive method, established learners' and educators' views about factors that contribute to poor performance in mathematics and physical science. Participants were purposefully selected from seven schools with poor pass rates in District 3 of Tshwane North. Focused group interviews with ten…

It is difficult for the students to understand some concepts related to the chemistry education such as complex formation, central ion, ligand, free electron pair, acceptor, donor, stability constant of complex and concealing. In those cases, demonstrating two dimensional models and using various molecular graphics programs on computers could be…

The purpose of this study was to investigate the difference in attitude toward and achievement in science between boys and girls in grade two (n=129) and in grade five (n=154) and to compare the differences found for elementary school students to those found previously for middle school students. For this study, "attitude toward science" was…

This report provides a summary for the years 1993 through 1997 of district and school-level results in Washington on the Comprehensive Tests of Basic Skills, fourth edition (CTBS/4) for grades 4 and 8 and the Curriculum Frameworks Assessment System (CFAS) for grade 11. For grades 4 and 8, the average national percentile scores in reading,…
