Three mathematics software packages, MathCAD, Point Five, and TK Solver Plus, are described and compared. The packages were rated on the accompanying documentation, ease of learning, ease of use, matrix operations, equation solving capability, versatility, use of units, generation of graphs and tables, readability of output, and overall…

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

Describes the impact of North Carolina's testing program in chemistry on curriculum and instruction from teachers' perspectives. A random sample of 100 teachers received a questionnaire yielding a usable sample of 48, of which 8 were interviewed. Results suggest testing is making the chemistry curriculum more uniform across the state. It is not…

At Boston College (Massachusetts), chemistry faculty are incorporating advanced technology into the classroom to motivate students to further study. A new $31 million chemistry center allows computer-based simulated experiments, computer-assisted instruction, and advanced graphics for visualization. Despite use of incentives, some student…

A model for problem solving stressing both psychological and cultural influences is presented. This model is based on the analyses of how graduate students (n=10) solve organic synthesis problems, along with two models of problem solving and a constructivist epistemological stance. (KR)

The uses that chemistry students (undergraduates, postgraduate, and trainee teachers) make of analog models when relating equations to projects were identified. Although only a restricted use of such models were found, and for none of the reasons valued by practicing chemists, patterns were identified. The implications for chemical education at…

Helping students to make essential connections of science content is often difficult, yet necessary to ensure a true understanding of science. A teacher offers insights on how pyruvic acid can be used to help students make connections in chemistry and biology. (ZWH)

Presents a structured, integrated continuing education program for university science and engineering reference librarians. Program components, including departmental tours, reference collection tutoring sessions, extensive subject-specific projects, and subject-related, hands-on exercises, are described. Program evaluation results are presented,…

Described is an activity in which students determine the percent composition of zinc and copper in pennies minted before and after 1982. Students also use pennies to show the natural relative abundance of isotopes and to explain how the weighted atomic mass of the elements is determined. (KR)

Described is how the construction of a breathalyzer was used by high school students to focus on a variety of concepts and principles of science and mathematics. The procedure for constructing the breathalyzer, related material, and summary are included. (KR)

An approach that may be used to introduce the fundamental ideas of thermodynamics using a mathematical background with the knowledge of the behavior of matter is described. The physical background, conservation of energy, predicting the behavior of a system, and solving problems are topics of discussion. (KR)

Demonstrations in which glyoxal may be substituted for formaldehyde, a known carcinogen, are presented. An acid-base clock reaction and a copper mirror on the inside of a test tube are described. Directions for the demonstrations and safety precautions are included. (KR)

Activities that show students a practical use for chemistry using common items such as food products, pharmaceuticals, and household products as sources of chemical compounds are presented. The importance of having adequate resource materials available for students is emphasized. (KR)

Reviews literature dealing with International Teaching Assistants and provides a rationale for teaching them pronunciation using cognitive-based field-specific methods. An account of the application of such a teaching method to instruct Chinese and Korean chemistry teaching assistants at a North American University is also given. (55 references)…

Discussed are the objectives, program development, program operation, seminar format, topics, faculty participation, attendance, and pitfalls and problems associated with this seminar series. A list of selected titles is provided. (CW)
