A study examined the relationship between the creative thinking of 114 13 to 14-year-old females and scientific problem-solving ability. The students did well in the "preliminary trialing" stage and were more proficient in "interpreting" and "performing" process skills. The other three components, "communication,""planning," and "reflecting,"…

Discusses report on the reading, mathematics, and science performance of Canadian 15-year-olds on the Organisation for Economic Co-operation and Development Program for International Student Assessment in 1999. Reports equity outcomes (effect of socioeconomic status on performance) in Saskatchewan are better than in the other provinces or any of…

Uses longitudinal study of differences between boys and girls in levels of mathematics and science achievement across grades 7 through 10 to extend hierarchical modeling to allow for regression among latent variables using a fully Bayesian approach. (Contains 30 references.) (PKP)

A number of recent national studies of student achievement in secondary school have reported differences between the Australian states and territories. State differences are often viewed as insubstantial or as simply reflecting sociodemographic factors, or differences between the states in the grades or ages of the students sampled. In this…

This mixed-methods study explored the effects of student-generated visualization on middle-schoolers' science concept learning. We compared students who visualized during study time with those who did not and found that visualization as a study strategy led to students' improved test performances (p=.02). However, middle schoolers' scores on a…

Under the adequate yearly progress requirements of the No Child Left Behind (NCLB) Act (2001), states are currently faced with the challenge of demonstrating continuous improvement in student performance in reading and mathematics. Beginning in 2007 to 2008, science will be required as a component of the NCLB Act. This article describes South…

Although gifted girls are closing the gap in math and science achievement, they continue to lose interest and drop out of math/science careers. An intervention was developed for talented at-risk young women that emphasized enhancing career identity and exploration, building science self-efficacy and self-esteem and reducing risky behaviors.…

This article discusses the author's observation that in his thirty-plus years in academics, many students who, by natural ability, interest, and work ethic, should have performed well in the sciences, but performed poorly. Many of these students are operating at the bottom rungs of Bloom's taxonomy (ladder), while college professors and industrial…

The primary purpose was to investigate the efficacy of a full year of single-sex (SS) teaching of science. The secondary aims were to locate any differentiation by set and gender, and to relate these to more proximal variables. Participants were 13 year olds. Higher set girls gave evidence of clear benefits overall, and higher set boys also,…

The consequences of the separate and unequal education policies of the apartheid years in South Africa persist into the present, and without specific redress measures will persist into the future. The disparities are most serious in the higher education gateway subjects Mathematics and Physical Science. In order to track education redress it is…

This article considers the problem of estimating dynamic linear regression models when the data are generated from finite mixture probability density function where the mixture components are characterized by different dynamic regression model parameters. Specifically, conventional linear models assume that the data are generated by a single…

The objectives of this paper are three-fold. First, a model is proposed for unifying massive amounts of conceptual and numerical information flowing from the measures of the accountability movement in Ohio and the materials that are publicly available to educators. Second, this model is translated into useable forms of information that help…

The purpose of this report is to provide descriptive data regarding the test scores of Milwaukee Parental Choice Program (MPCP) students in grades 4, 8 and 10 in reading, math, and science, as reported to the School Choice Demonstration Project 2008-2009. The tables, graphs, and histograms presented in this paper provide a snapshot of these…

The present study was conducted to investigate the degree of effectiveness of cooperative learning instruction over a traditional approach on 11th grade students' understanding of electrochemistry. The study involved forty-one 11th grade students from two science classes with the same teacher. To determine students' misconceptions concerning…

This longitudinal research tests the effectiveness of the SPRinG programme, which was developed through a collaboration between researchers and teachers and designed to provide teachers with strategies for enhancing pupil group work in "authentic" classroom settings. An evaluation study involved comparing pupils in SPRinG classrooms and…
