The purpose of this study was to track the development of fifth-graders' reading and writing skills in the context of ecosystems science content using an action research design. A collection of students' work, a researcher journal, video-taped class sessions, student science journals and a weekly book choice checklist were used as data sources.…

The grade three curriculum set out by the British Columbia Ministry of Education has four categories for science: Processes of Science, Life Science, Physical Science, and Earth and Space Science. Within each of these categories there are numerous topics to teach. For example, the physical science curriculum requires students to learn about…

There is substantial evidence that scientific teaching in the sciences, i.e. teaching that employs instructional strategies that encourage undergraduates to become actively engaged in their own learning, can produce levels of understanding, retention and transfer of knowledge that are greater than those resulting from traditional lecture/lab…

This study was conducted in a reform-based mathematics and science teacher education program in the USA, the Maryland Collaborative for Teacher Preparation (MCTP). The goal of the undergraduate program was to prepare upper elementary/middle level specialists in mathematics and science. One significant aspect of the MCTP was the expectation that…

The goal of this study is to analyze the images of science and scientists in science biographies written for children. We examined 12 biographies of historic and contemporary scientists written for primary/middle school children in relation to three dimensions: characteristics of scientists, nature and process of scientific knowledge, and social…

The following paper is intended as an exercise in "friendly criticism" of one of Harvey Siegel's and Mike Smith's ("Knowing, Believing and Understanding", this volume). I'm in substantial sympathy with the general thrust of their paper and my remarks merely provide some criticism of their discussion's conceptual coherence and clarity and a…

The learning difficulties for new entrant chemistry students from a multi-national, regional, tertiary education institution in the South Pacific were investigated using a purpose-designed diagnostic instrument. The instrument contained 25 items distributed across three themes: scientific reasoning, numeracy and scientific language literacy. The…

Today, more than at any other time in human history, biologists are or should be concerned about the morality of biological research and newly developed technologies. Two questions confront any scientist or science student concerned about morality and the life sciences. Is there some theoretical framework that might be used to assist in deciding…

This study examined the effect of a hypermedia-enhanced problem-based learning environment in astronomy on sixth-graders' science knowledge, attitude toward learning science, and motivation toward learning. It was found that the students had significantly increased their science knowledge from pretest to post test and also retained much of what…

A time of upheaval and innovation, the American Colonial Period (1600-1775) was marked by New World settlers' struggles to adapt to a life that lacked anything familiar or prefabricated. The period provides a rich opportunity to study the contributions of the colonists across multiple disciplines. In the fall of 2003, a team of eighth-grade…

The purpose of this research was to enhance self-efficacy beliefs, chemistry content, and pedagogical content knowledge of middle grades teachers by incorporating specific design elements into professional development. This study analyzed the influence of program design on achieving gains in personal science teaching self-efficacy, outcome…

A curriculum unit for middle school Earth Science called "What's on Your Plate?" was designed. The unit was implemented in several middle and high school classrooms in California and Massachusetts. In the first implementation, the total number of students who participated was 1100. The unit was designed with two main pedagogical…

This study examined the writing strategies and text characteristics associated with discovering a scientific principle by writing about an experiment. Sixty-four university students (non-science majors) carried out a physics experiment concerning either buoyancy, or the forces acting on a balance scale, then wrote an informal journal-style note…

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old…

In view of students' alternative conceptions about basic concepts in astronomy, we conducted a series of constructivist activities with future elementary and junior high school teachers aimed at changing their conceptions about the cause of seasonal changes, and of several characteristics of the Sun-Earth-Moon relative movements like Moon phases,…
