Presents research and related design features that distinguish a new generation of teacher enhancement efforts along with the design and results of evaluation approaches for a specific program. (KHR)

Presents a 41-word wordsearch puzzle on describing electron transport and oxidative phosphorylation. (YDS)

Describes a classroom demonstration supported by the guided-inquiry experience that focuses on separation techniques and other solvent-dependent processes, such as reaction-solvent selection. (Contains 13 references.) (YDS)

Describes strategies for facilitating student science investigations and alleviating common weaknesses associated with student performance. Includes checklist criteria for performance on investigative tasks and an example of an assessment rubric for the investigation of the effect of temperature on enzyme activity. (Author/KHR)

Reports on the possibility of restructuring physics and chemistry departments and merging others at British universities. Suggests modifications of the course content for greater acceptance by students. Concludes that the logic of the committee's recommendations rests in the subsequent ability of certain departments to grow. (RT)

Surveyed are the etymology and the reason scientists coined a specific name for a newly discovered element. Approaches to naming from a historical viewpoint are considered. (CW)

Reports on a 30-year-old longitudinal study of reactions in gels. Described are reactions and crystal growth in silica gels and diffusion studies of the Liesegang ring formation. Color photographs showing the reactions and graphs upon the diffusions are presented. (YP)

Discusses the background and events which lead to a career devoted to plant biochemistry and the study of vitamin synthesis. Describes laboratory studies which demonstrated that, in mammals, vitamin A is formed from beta-carotene as it crosses the intestinal wall. (RT)

Describes how environmental education can be realized by using the holistic approach of the Theme Centered Interaction (TCI). Explains the philosophy of TCI as well as its application in chemical education and presents several classroom examples. (Author/JRH)

Explores changes in students' conceptions about solution chemistry in the context of instruction based on collaboration between a researcher and an experienced teacher attempting to implement strategies from the literature on conceptual change. (ZWH)

Provides an introduction to the cubic equation and its solution along with its application to van der Waals' equation of state. (ZWH)

Reports an interpretive examination of four teachers' use of analogies to teach chemistry. Suggestions for how science teacher education can be informed by case studies of teaching in context, in this instance of analogy-inclusive teaching by four experienced chemistry teachers, are provided. (ZWH)

Describes two spreadsheets for producing acid-base titration curves, one uses relatively simple cell formulae that can be written into the spreadsheet by inexperienced students and the second uses more complex formulae that are best written by the teacher. (JRH)

Discusses doing science experiments on a small scale in order to reduce the quantity of chemicals used in science classes. (MKR)

Presents food science experiments designed for high school science classes that aim at getting students excited about science and providing them with real-life applications. Enables students to see the application of chemistry, microbiology, engineering, and other basic and applied sciences to the production, processing, preservation, evaluation,…
