Despite its positive impact on students' understanding of the nature of science and science content knowledge, few secondary science teachers incorporate the history of science into their instruction. This article describes the effects of an online history of science course on preservice teachers' perceptions of and content and pedagogical…

The number of experimentally derived structures of cellular components is rapidly expanding, and this phenomenon is accompanied by the development of a new semiotic system for teaching. The infographic approach is shifting from a schematic toward a more realistic representation of cellular components. By realistic we mean artist-prepared or…

A course, called Nature of Science, is described as developed over the eight years it has been presented to nonscience majors at a liberal arts college. The aims of the course are to show important ties between science and those disciplines in which nonscience students' primary interests lie; to develop in nonscience students the recognition that…

Presents three dimensional models of biological pathways for the following cycles: carbon, nitrogen, sulfur, and a combination of the three. Discusses steps involved in each cycle and breaks each cycle into trophic and environmental regions. (MVL)

Within primary and secondary school technology education, engineering has been proposed as an avenue to bring about technological literacy. Different initiatives such as curriculum development projects (i.e., Project ProBase and Project Lead The Way) and National Science Foundation funded projects such as the National Center for Engineering and…

A project was conducted to develop a curriculum package that defined the specific math, science, and language arts skills presently being taught at a vocational skills center that offered training in 20 job skill areas and served an 11-school district. The information gathered during the project was to serve as a basis for granting cross-credit to…
