The "Framework for K-12 Science Education" details ambitious goals for students' learning of science content and practices. However, this document provides science teachers little guidance about instructional practices that are central to helping students achieve these goals. Research indicates that a teacher's instructional…

This article reports on our work of developing a learning progression focusing on K-12 students' performances of using energy concept in their accounts of carbon-transforming processes in socio-ecological systems. Carbon-transforming processes--the ecological carbon cycle and the combustion of biomass and fossil fuels--provide all of the energy…

This research examines science-simulation software available for grades 6-12 science courses. The study presented, funded by the National Science Foundation, had two objectives: a literature synthesis and a product review. The literature synthesis examines research findings on grade 6-12 student learning gains and losses using virtual laboratories…

As the context of human life expands from personal to global, a new vision of scientific literacy is needed. Based on a synthesis of the literature and the findings of an online survey of South Korean and US secondary science teachers, we developed a framework for scientific literacy for South Korea that includes five dimensions: content…

The goal of the Inquiry Synthesis Project was to synthesize findings from research conducted between 1984 and 2002 to address the research question, "What is the impact of inquiry science instruction on K-12 student outcomes?" The timeframe of 1984 to 2002 was selected to continue a line of synthesis work last completed in 1983 by Bredderman…

This study deals with the development of system thinking skills at the elementary school level. It addresses the question of whether elementary school students can deal with complex systems. The sample included 40 4th grade students from one school in a small town in Israel. The students studied an inquiry-based earth systems curriculum that…

In order to compete in a global economy, students are going to need resources and curricula focusing on critical thinking and reasoning in science. Despite awareness for the need for complex reasoning, American students perform poorly relative to peers on international standardized tests measuring complex thinking in science. Research focusing on…

Over the past several decades, there has been a tremendous growth in our understanding of genetic phenomena and the intricate and complicated mechanisms that mediate genetic effects. Given the complexity of content in modern genetics and the inadequacy of current instructional methods and materials it seems that a more coherent and extensive…

Nearly 6,000 science questions collected from five different web-based, TV-based and school-based sources were rigorously analyzed in order to identify profiles of K-12 students' interest in science, and how these profiles change with age. The questions were analyzed according to their topic, thinking level, motivation for and level of autonomy in…

This study investigated the development in students' nature of science (NOS) views in the context of an explicit inquiry-oriented instructional approach. Participants were 18 seventh-grade students who were taught by a teacher with "appropriate" knowledge about NOS. The intervention spanned about 3 months. During this time, students were engaged…

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…

This article describes a 3-year study of school visits to four natural history museums and addresses the research agenda with regard to out-of-school learning. More specifically, the findings focus on the "process of learning" in museums. Comprehensive data collection allowed for an analysis of patterns of guided visits, the way the scientific…

In this article, we describe a preliminary study that integrates research on engineering design activities for K-12 students with work on microworlds as learning tools. Here, we extend these bodies of research by exploring whether--and how--authentic recreations of engineering practices can help students develop conceptual understanding of…

This study investigated the national impact of the Collaboratives for Excellence in Teacher Preparation program (CETP). Impact of the program was examined in two different settings: institutions of higher education, and K-12 science and mathematics classrooms. The focus of this study was to determine the impact of the CETP program on the…

Women continue to be underrepresented in the fields of science, technology, engineering, and mathematics (STEM). One factor contributing to this underrepresentation is the graduate school experience. Graduate programs in STEM fields are constructed around assumptions that ignore the reality of women's lives; however, emerging opportunities may…
