International educational comparisons are relatively recent phenomena and have long been the source of international debate. Since the formation of the International Association for the Evaluation of Educational Achievement (IEA) in the 1950s, assessments have grown increasingly more valid and reliable. TIMSS is an exemplary attempt at…

This article describes 1st-year experimental effects of a large-scale reform providing professional development to elementary school teachers to implement an extended, inquiry-oriented science curriculum. Known as "immersion teaching" because it "immerses" teachers and students in the full cycle of scientific inquiry, this…

The disparity in persistence between males and females studying physics has been a topic of concern to physics educators for decades. Overall, while female students perform as well as or better than male students, they continue to lag considerably in terms of persistence. The most significant drop in females studying physics occurs between high…

The discussion here covers five articles that are linked in the sense that they all treat population invariance. This discussion of population invariance is a somewhat broader treatment of the subject than simply a discussion of these five articles. In particular, occasional reference is made to publications other than those in this issue. The…

Despite a well established body of international literature describing the effect of test anxiety on student performance in a range of assessments, there has been little work conducted on samples of students from the UK. The purpose of this exploratory study is two-fold. First, to establish the relationship between test anxiety and assessment…

This study examines the effects of public preschool expenditures on the math and science scores of 4th graders, holding constant child, family, and school characteristics, other relevant social expenditures, and country and year effects, in 7 Organisation for Economic Co-operation and Development (OECD) countries--Australia, Japan, the…

The Organisation for Economic Cooperation and Development (OECD) underpins its extensive policy work with strong databases of comparable statistics and indicators with which it compares countries. In 2000, it extended its education database with its first collection of data on the performances of 15-year-olds in reading, mathematics and science…

During the 2009-10 academic year, 1,444 8th grade students in the Canton City, Plain and Marlington Local School Districts (hereafter called Stark students) took the EXPLORE Test as part of a pilot project, "Ready to Go: Increasing Eighth Grade Readiness," sponsored by the Stark Education Partnership with funding from the Ohio College…

This report summarizes the activities and findings of the external evaluation of the "Science: It's Elementary" (SIE) program during the period from July 2009 through June 2010. The SIE program is managed by ASSET Inc. and overseen by the Pennsylvania Department of Education (PDE). SIE is an initiative aimed at improving elementary…

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,…
