The fundamentals of two surface techniques--secondary-ion mass spectrometry (SIMS) and ion-scattering spectrometry (ISS)--are discussed. Examples of how these techniques have been applied to surface problems are provided. (JN)

Examines some of the possibilities for applying the noise spectroscopic technique as well as the origin of noise (or fluctuations) which accompanies transport in physical systems. Indicates that fluctuation techniques are useful in studying liposome and micelle suspensions, liquid-liquid surfaces, semiconductors, and semiconductor devices. (JN)

Discusses seven key concepts in Ausubel's learning theory which function to guide research and teaching. Also discusses concept mapping and Gowins Vee, providing examples of how they are used in chemistry instruction. (JN)

Indicates that the language in which a multiple-choice question is couched may be a significant factor in student performance. Effects of changing key words, terms of quantity, negative to positive forms, and from passive to active voice are discussed. Also discusses the effect of rewording long or complex questions. (JN)

Indicates that present curricula are not preparing citizens to deal with critical social issues, in particular, those related to the environment, energy, food supply, and population problems. Offers 10 suggestions to help remedy the situation. (JN)

Compared the quality of preparation and attrition of students in a traditional remedial chemistry course with students in a remedial course having a personalized system of instruction (PSI), self-paced format. Although the PSI course suffered heavy attrition, PSI students did significantly better in later courses, which held up over time. (JN)

Presented are goals and a topical outline for a one-semester chemistry course for students in the health professions. The outline is intended to be a model rather than an "official" course in the field. Several points are offered, particularly for faculty new to teaching such a chemistry course. (JN)

Describes the overall design, content, and use of Chemical Literature Exercises and Resources (CLEAR), a set of materials which introduces students to the chemical literature. Indicates that, overall, student evaluations of the CLEAR materials were very positive. (JN)

Describes two simulations, written for Apple II microcomputers, focusing on scientific methodology. The first is based on the tendency of colloidal iron in high concentrations to stick to fish gills and cause breathing difficulties. The second, modeled after the dioxin controversy, examines a hypothetical chemical thought to cause cancer. (JN)

Discusses algebraic programing languages, availability of these languages, and programing problems. Also discusses the future of these languages in chemical research and chemical education. A program illustrating the general algebraic and algebraic matrix manipulating capabilities of the REDUCE language is included. (JN)

Discusses the use of special portapunch cards in the testing and grading of large student populations. The cards can be processed routinely at a batch station by laboratory staff having little knowledge of computers. The system not only allows cheap and reliable marking but also can accommodate a variety of tests. (JN)

Project CHEMLAB has prepared a database which focuses on laboratory experiments suitable for high school through graduate or professional school levels. The scope of the project, the structure of the database, database features, and computer searching are discussed. (JN)

Background information, procedures, and results are provided for an experiment in which students: (1) construct an immobilized penicillinase electrode; (2) evaluate electron response as a function of penicillin concentration; and (3) study effects of solvent compositions, ionic strength, and equilibrium time upon electrode response. (JN)

Describes an undergraduate experiment for the potentiometric determination of urea based on the physical entrapment of urease on the tip of an ammonia gas sensor. An advantage of this technique is the ease with which the ammonia electrode can be converted to a urea electrode. (JN)

Describes a senior-level experiment dealing with the synthesis and characterization of a perovskite. Since most perovskites are cubic, their characterization by x-ray diffraction is simplified. In addition, magnetic ordering may be observed and the effects of a Jahn-Teller distortion seen. (JN)
