Focuses on the history of the organization of chemical principles in chemistry textbooks. Describes a higher-order organizing principle, based in chemical logic and understanding, from which topics and order of presentation are derived. Provides an example of a biochemistry curriculum developed using this organizing principle. (DDR)

Focuses on the effects of the lack of coordination in the teaching of introductory subjects in chemistry, biology, and physics. Argues that some of the more interesting topics in these fields lie on the border with another field. For example, biochemistry topics may be more interesting to students than chemistry or biology topics. (DDR)

Describes the role of the New Traditions Consortium, a consortium that identifies mechanisms of pedagogical and instructional change, implements them at different types of institutions, and evaluates their effects on student learning. (DDR)

Presents a demonstration that is a safe blend of two other vivid and memorable demonstrations. Combines two exothermic reactions involving granulated sugar to devise a reaction that produces a small amount of smoke and a growing column of black carbon. (DDR)

Describes absorption spectroscopy experiments that allow students to explore the mechanisms by which sunscreens and sunglasses provide protection from ultraviolet radiation. Exposes students to absorption phenomena in an engaging way. (DDR)

Describes a computer course for undergraduate chemistry students that provides them with sufficient experience to be capable of making independent progress in solving chemical problems using computers. Consolidates undergraduate computer-related material into a single course. (DDR)

Describes a way to enhance student/instructor communication through regular student feedback on key concepts. Argues that examinations also serve this purpose but are too infrequent and that anonymous quizzes can be used effectively. (DDR)

Outlines the development of a curriculum in molecular science that prepares those students who have a deep understanding of chemistry concepts and principles, have collaboration skills, are able to use modern technology, and can write about chemistry. (DDR)

Cites the shortcomings of the traditional educational experiences of chemists. Focuses on their training in engineering and concludes that training is lacking in the areas of mass balances in flow processes, heat balances, reactors, separation processes, and scaleup. (DDR)

Provides plans for simple, inexpensive teaching aids and equipment for visually impaired children. Details for building null detectors, electronic thermometers, and calorimeters are included. (DDR)

Argues for the use of instruments in introductory level chemistry and presents multiple perspectives on the issue. Reasons for employing instrumentation include the ability of introductory classes to reach a large number of students, the need to model situations in which scientists work, and student expectations regarding the use of technology.…

Argues that visual images can act as conceptual pegs for concepts or complicated procedures and help students perform better in the cognitive, affective, and manipulative domains of the laboratory. Conclusion was based on a study of chemistry laboratory students (N=83). (DDR)

Illustrates the interdependent issues associated with modern materials science and suggests that the performance of a computer depends on the physiochemical properties of its components. Focuses on selected materials critical to a computer's construction. Contains 69 references. (DDR)

Describes a student activity that focuses on color and the production of images on computer monitors. Students discover the rules for making colors through the use of a magnifying glass and a computer monitor. Includes some tips for integrating the activity into the curriculum. (DDR)

Provides information on the use of a toy engine with no visible power source that is designed to demonstrate the conversion of low-temperature thermal energy to mechanical energy by means of a Nitinol loop wrapped around a system of two pulleys. (DDR)
