Recent calls for reform in K-12 science education and the National Academy of Engineering's Grand Challenges for Engineering in the 21st Century emphasize improving science teaching, students' engagement, and learning. In this study, we designed and implemented a curriculum unit for sixth-grade students (i = 1305). The curriculum unit integrated…

Given the large continued investment by the federal government in programs that promote academic success and the pursuit of advanced degrees in the sciences among members groups traditionally underrepresented in the sciences, there is a strong need for research which provides rigorous investigations of these programs and their impact on the target…

Teacher knowledge of science content is an important but under-studied construct. A curricular and professional development intervention consisting of a fifth grade science curriculum, teacher workshops, and school site support was studied to determine its effect on teachers' science content knowledge as measured by a science knowledge test,…

Even though school administrators and their leadership practices are rarely explored within science education research, our recent efforts to understand organizational influences on achievement disparities induced an elevated regard for elementary school principals. In this paper, we report on policy buffering by principals at schools whose…

This study examined the effect of a quasi-experimental project on fifth grade English learners' achievement in state-mandated standards-based science and English reading assessment. A total of 166 treatment students and 80 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted…

This longitudinal study of middle school science teachers explored the relationship, if any, between teacher participation in whole-school, sustained, collaborative professional development and student achievement in science. Eleven teachers from Glendale Middle School participated in the Discovery Model Schools Initiative 2-week summer institute,…

Finnish students' opinions about the frequency of learning activities and communication in the Finnish science classroom, their interest in science and science studies and careers, their sense of self-efficacy, and their beliefs about their own competence as well as their performance in science are analyzed based on PISA 2006 Scientific Literacy…

Examines effects of NSF institute participation by secondary teachers. Tests alternative hypotheses that (1) an increase in student achievement associated with teacher inservice work may be accompanied by more positive attitudes towards science; or (2) that teachers may increase their students' achievement at the expense of less positive science…

Investigated various factors related to a project designed to increase scientific literacy of two age groups by simultaneously exposing middle school children and their parents to short science courses. Findings, among others, show that parents and children made significant gains in learning and that they found the experience enjoyable and…

This article reports a study on using data mining to predict K-12 students' competence levels on test items related to energy. Data sources are the 1995 Third International Mathematics and Science Study (TIMSS), 1999 TIMSS-Repeat, 2003 Trend in International Mathematics and Science Study (TIMSS), and the National Assessment of Educational…

The impact of summer science-enrichment programs on high-school students' science motivation and confidence was evaluated in a 7-month period following program completion. The programs took place on a college campus. The splashdown effect was defined as program-related changes the program graduates recognized in themselves that became apparent to…

A comprehensive, quantitative evaluation of an educational intervention program designed to reduce the attrition of minorities from the biological sciences was undertaken to ascertain whether such efforts adequately address the problem. Program participants had greater odds of persisting in basic math and science courses, and of graduating in…

Assesses the effects of a one-day inservice program for junior high school science teachers emphasizing an activity-oriented science curriculum and management strategies necessary for such a curriculum. Results indicate inservice positively affects teacher attitudes toward strategies and student achievement in science. (DS)

Investigated whether there was a difference in achievement between ninth and tenth grade students upon completion of a year of biology. A comparison of mean scores on the final examination showed there was no significant difference between grade levels. (MLH)

Assesses patterns of enrollment in science, science achievement, and attitudes of students in grades 3-12 representing the 4 major ethnic groups in Hawaii. Results indicate that more differences were accounted for by ethnicity and even grade than by gender and there was little interaction between ethnicity and gender. Contains 78 references.…
