Describes a pilot study aimed at exploring the possibility of introducing simulation-based homework into junior high school ninth grade science classes studying electric circuits. Analyzes students' views in relation to their prior computer experience and their achievement, and discusses results from questionnaires and interviews that show…

Examined discourse components, interaction patterns, and reasoning complexity of eighth-graders in two science classrooms as they constructed mental models of the nature of matter. Found that teacher-guided discussions were more efficient for attaining higher reasoning levels and higher quality explanations, but peer discussions were more…

The National Research Council (1996), the American Association for the Advancement of Science (1993) and the National Science Teachers Association (2004) all posit that quality science instruction for all students is imperative in promoting scientific literacy that extends into adulthood. Hands-on, inquiry based experiences are effective means of…

The purpose of this research effort was to examine Black male students' self-perceptions of academic ability and gifted potential in science. The purposeful sample consisted of nine Black males between the ages of 14 and 18 years. Four categories of self-perceptions of academic ability and gifted potential emerged from the data. These included:…

Most people are frustrated with the current scientific method presented in textbooks. The scientific method--a simplistic model of the scientific inquiry process--fails in most cases to provide a successful guide to how science is done. This is not shocking, really. Many simple models used in science are quite useful within their limitations. When…

This report describes an experiment to introduce freshmen science students to inquiry-based learning. The overarching theme was the communication of scientific information to the public by the mass media. Students, working in groups, deconstructed news items (many dealing with basic biomedical issues) and assessed the veracity of statements with…

The technology now exists to construct physical models of proteins based on atomic coordinates of solved structures. We review here our recent experiences in using physical models to teach concepts of protein structure and function at both the high school and the undergraduate levels. At the high school level, physical models are used in a…

The Studio Model was developed at Rensselaer Polytechnic Institute (RPI) to improve teaching and learning in introductory science classes. The study reported in this article explored the efficacy of the Studio Model at the high school level. The Studio Model combines collaborative learning with the use of online materials designed to support and…

Using the US national sample from the 1995 Third International Mathematics and Science Study (TIMSS), this study examined students' competence levels in understanding the matter concept at grades 3, 4, 7, 8 and high school graduation, and compared them to the expectations in the US national science education standards. It was found that…

Because the National Science Education Standards (1996) outline specific things K-8 students should know about plants, and previous data indicated that elementary students had difficulty understanding some major ideas about plants and plant growth, the authors of this article thought it appropriate to initiate an investigation to determine the…

Historical perspectives on science serve to humanize the sciences, increase student motivation, communicate academic content, and convey the nature of science. This paper briefly reviews pertinent literature regarding the history of science and narrates the author's experiences of incorporating historical perspectives in high school biology…

While a voluminous lecture hall can present obstacles to effective teaching and learning, large classrooms containing more than 100 students also present teaching opportunities. The lecture hall offers an excellent arena for demonstrating concepts that lend themselves to demonstrations and something this author refers to as "group performances."…

This article uses a functional view of language to frame and analyze issues of language and content in mainstream classrooms. Describing a Western Canadian grade one/two science class, it examines how a teacher and her class of young ESL students were able to build up a simple theory of magnetism in a scientific register, link its technical terms…

Teaching and learning science through the use of familiar contexts has been advocated for several decades. Many take the use of context in science lessons to mean the use of resource materials that involve common scenarios or themes, or activities. This paper reviews a lesson identified by a teacher as a lesson taught in context. The data…

Biology knowledge and understanding is important not only for the conversion of the loftiest dreams into reality for a better life of individuals but also for preparing secondary pupils for such fields as agriculture, medicine, biotechnology, and genetic engineering. But a recent study has revealed that many aspects of school science (biology…
