Two leading science educators provide a comprehensive, state-of-the-field analysis of current trends in the research, policy, and practice of science education. This book offers valuable insights into why gaps in science achievement among racial, ethnic, cultural, linguistic, and socioeconomic groups persist, and points toward practical means of…

The "No Child Left Behind Act of 2001 (NCLB)" is designed to achieve an ambitious goal: All children will be proficient in reading and mathematics by the 2013-14 school year. A key strategy for achieving this goal is accountability. Based on findings from two federally funded studies--the Study of State Implementation of Accountability…

Low high school graduation rates continue to be a challenge in American public education. The pressure to meet the demands of adequate yearly progress (AYP) under the No Child Left behind Act of 2001 has led to an achievement gap in student performance between science and other core subjects, namely English, math, and social studies, on the…

Whether in health, in education, or in material well-being, some children will always fall behind the average. The critical question is -- how far behind? Is there a point beyond which falling behind is not inevitable but policy susceptible, not unavoidable but unacceptable, not inequality but inequity? There are no widely agreed theoretical…

The Exploring Florida Science project goals were: (1) increasing content knowledge of secondary science teachers, specifically in topics that are important to the future of the state, and (2) providing secondary science students with digital media for use in project-based learning. A team of instructional designers, educators, scientists, web…

In this study, we analyzed the quality of students' written scientific explanations found in notebooks and explored the link between the quality of the explanations and students' learning. We propose an approach to systematically analyzing and scoring the quality of students' explanations based on three components: claim, evidence to support it,…

This study of teacher effectiveness and student achievement in science demonstrated that effective teachers positively impact student learning. A general linear mixed model was used to assess change in student scores on the Discovery Inquiry Test as a function of time, race, teacher effectiveness, gender, and impact of teacher effectiveness in…

Researchers are becoming aware of the influence of students' presuppositions in directing their construction of science concepts. When these are entrenched and drastically nonscientific, they predispose the children to alternative explanatory frameworks that are inhibiting, especially in a knowledge domain such as genetics. In this study, we…

Primary school data from the Third International Mathematics and Science Study (TIMSS) are analyzed in this article to examine performance difference between 3rd and 4th grades. Score comparisons are determined across all TIMSS items in each of the participating countries, using computer technology and programming to complete the thousands of…

Supports the use of assessment probes to measure scientific achievement. Provides several examples and discusses the characteristics of effective probes. (DDR)

Analyzed the mathematics achievement of immigrant children in the United States, Canada, England, Australia, and New Zealand using data from the Third International Mathematics and Science Study. Immigrant students' mathematics achievement was lower than others only in England, the United States, and Canada. Non-English language background was…

On an overcast Sunday afternoon April 2005, a crowd of teenagers and their families file through the front gates of Great America theme park, located along a boulevard in the polished suburban circuitry of Silicon Valley. Emerging briskly from this migration of bodies onto the steps of the park auditorium, flanked by his mother and father, is a…

The East Asian countries are known for their high scores on international comparisons of math and science achievement. This does not necessarily mean that the U.S. should rush to adopt their practices and abandon its own strengths. Yong Zhao examines education reforms in math and science from an international perspective and discusses implications…

The purpose of the present study was to improve a multivariate multilevel model in the research literature which estimates the consistency in the rates of growth between mathematics and science achievement among students and schools. We introduced a new multivariate multilevel model via a latent variable approach. Data from the Longitudinal Study…

This article considers the problem of educational placement. Several discriminant techniques are applied to a data set from a survey project of science ability. A profile vector for each student consists of five science-educational indicators. The students are intended to be placed into three reference groups: advanced, regular, and remedial.…
