Describes the development of English, Welsh, and Israeli preservice secondary science teachers from immediately before to immediately after their initial teacher education courses. Finds that all students passed through a dynamic process of transformation and changed their perceptions about teaching, but the British students' ideas were more…

The aim of this study is to investigate and compare level of understanding of eighth-grade students and student teachers in their final year in the science education department related to concepts of solution, gas, and chemical change. A qualitative and quantitative methodology was used for this investigation. Open-ended questions and group…

The NASA's Mars Student Imaging Project (MSIP) is led by the Arizona State University (ASU) Mars Education Program, a major partner of NASA's Mars Exploration Program. MSIP is based on the National Science Education Standards and includes curriculum on terrestrial planet characteristics, experimental design, and proposal writing. Three spacecraft…

Using the seasons in the science classroom increases student observation skills as they focus on subtle differences such as shades of color and differences in structures. In this article, the author presents a variety of activities that can help students identify and demonstrate patterns and changes in leaf or plant development. The ability to…

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…

Scientists and students often believe that if they just think harder about a problem, a solution will follow. However, thinking about one's thinking, or using metacognition, can be a more productive expenditure of mental energy. Introducing students to metacognition allows them to discover the value of reflection. This article presents a lesson on…

The RAFT technique (Santa 1988) is a writing strategy that helps students understand their "Role" as a writer, the "Audience" they will address, various "Formats" for writing, and the expected "Topic" or content. This article discusses the RAFT writing strategy used by the students to address land development issues. The authors facilitated…

This hypothesis-driven laboratory exercise teaches how DNA evidence can be used to investigate an organism's evolutionary history while providing practical modeling of the fundamental processes of gene transcription and translation. We used an inquiry-based approach to construct a laboratory around a nontrivial, open-ended evolutionary question…

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…

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…

In this article, the author features the lawsuit, which Americans United filed jointly with the American Civil Liberties Union of Pennsylvania asserting that the Dover School Board has violated the constitutional separation of church and state. He traces that the controversy stems from Tammy J. Kitzmiller's and other concerned parents' strong…

One of the central concerns of English as a Second Language (ESL) education within many English-speaking countries has been the relationship between content and language teaching. In Victoria, a state of Australia, the educational policy of mainstreaming ESL is presented as a means of catering to the language learning needs of ESL students within…

This study investigated professional thinking about pedagogical aspects of technology use in mainstream classroom practice. It focuses on the systems of ideas which frame teacher accounts of the successful use of computer-based tools and resources in the core subjects of English, Mathematics and Science at secondary-school level. These accounts…

The investigators sought to design an instructional unit to enhance an understanding of the nature of science (NOS) by taking into account both instructional best practices and suggestions made by noted science philosopher Thomas Kuhn. Preservice secondary science teachers enrolled in a course, "Laboratory Techniques in the Teaching of Science,"…
