The purpose of the study is to compare problem based learning (PBL) and lecture-based learning (LBL) in Hong Kong secondary students' science achievement. Secondary One students were divided into two groups: group A (n = 37), was taught two topics: "Human Reproduction" and "Density" through PBL; group B (n = 38) was taught the…

In this study, 149 low-income, ethnically heterogeneous, fourth- and fifth-grade students completed self-report surveys in the fall and spring of 1 academic year. We examined classroom climate (satisfaction, cohesion, friction, task difficulty, and competition) and school belonging in relation to language arts and math and science self-efficacy,…

Preliminary pilot studies and a field study show how a generalizable conceptual framework calibrated with item response modeling can be used to describe the development of student conceptual understanding in chemistry. ChemQuery is an assessment system that uses a framework of the key ideas in the discipline, called the Perspectives of Chemists,…

The assimilation and synthesis of knowledge is essential for students to be successful in chemistry, yet not all students synthesize knowledge as intended. The study used the Learning Preference Checklist to classify students into one of three learning modalities--visual, auditory, or kinesthetic (VAK). It also used the Kolb Learning Style…

Austin Independent School District provided summer programs in 2010 for students to accelerate academic learning, maintain academic skills between school years, recover course credits, retake state achievement tests, or experience school-level transition activities. This is the full report, a research brief was also published. [For the research…

This report summarizes AISD 2008-2009 program evaluation results for a state grant to improve students' grades in science courses, to increase students' chances of graduating, and to increase 10th and 11th-grade students' scores on the state science test.

This paper reports on implications of a research study with a group of 44 Indigenous middle school students learning the science concepts of energy and force. We found the concepts of energy and force need to be taught in English as we failed to find common comparable abstract concepts in the students' diverse Indigenous languages. Three…

This study describes the efficacy of a novel tool, mini-lecture movies, in teaching Web based general chemistry. The analysis shows a marked improvement in student learning, as evidenced by a corresponding increase in homework and final exam scores. Students with access to mini-lecture movies scored 11.2% (p = 0.016) higher than students who did…

A model linking children's perceptions of adults' gender stereotypes about mathematics and science ability, children's stereotypes, and children's perceptions of their own mathematics and science competence was tested in 302 fourth, sixth, and eighth graders. When boys believed that adults hold more traditional stereotypes, they tended to hold…

A follow-up analysis of data collected in 2003 was conducted to determine the effect of peer helping programs on student achievement at 47 middle schools in Western New York. The mean scores and the percent of students achieving at or above the New York State passing cores on The New York State Eighth Grade Science Achievement Test and The New…

The purpose of this study was to determine whether Science, Technology, and Society (STS) learning increases student concept mastery, general science achievement, use of concepts in new situations, and attitudes toward science in middle school classrooms. The study involved two teachers and fifty-two students in grades 6 through 8. Two sections of…

As other countries vigorously promote rapid advancement in science, optimizing the participation of all students in the United States in science is imperative. This study focused on African American students and examined their science achievement in relation to Black Cultural Ethos (BCE), a construct rooted in psychology. Via qualitative and…

During the three presidential debates this fall, both John McCain and Barack Obama opened by thanking their university hosts. If not for their locations, it's likely one would not have heard the words "college," "university," or "higher education" even uttered in the debates. Indeed, it wasn't until the final debate that Senator McCain mentioned…

The aim of the present contribution is to investigate similarities and differences of strengths in science competences between countries, based on TIMSS 2003 data. Analyses are based on systematic investigation of patterns of p values for individual science items. Hierarchical cluster analysis was applied to establish meaningful groups of…

Studies of test dimensionality indicate that many large-scale science assessments measure multiple dimensions. These findings have reinforced the perspective that science achievement is an inherently dynamic process and that there is benefit in reporting subscores in science. A limitation with some of these studies is that they fail to indicate…
