Describes a technique for projecting reactions in test tubes by turning an overhead projector on its side. The technique can be used with any ordinary projector. (JM)

A 2-week unit on toxic chemical waste disposal is used in a physical science course for nonscience majors. Descriptions of the unit, supplementary student activities, and student library project are provided. Also provided are selected student responses to a five-question survey on the unit. (JN)

Provides examples which illustrate how microcomputers can facilitate various aspects of chemistry instruction, focusing on computer assisted instruction (CAI) and on the simulation of chemistry experiments. Brief comments on writing CAI programs are also included. (JN)

Provides names and addresses of organizations which supply information to individuals looking for advice about careers in chemistry and chemical engineering. Includes descriptions of American Chemical Society (ACS) publications on this topic. They include continuing education aids, aids for college/high school students, information for foreign…

Describes an electronic thermometer using a precision temperature sensor (includes detailed schematic of circuits) and inexpensive ring holders for round-bottomed flasks. Also describes a method for reducing funnel breakage. (JN)

Investigated the validity of the assumption that arranging items in objective tests in order of increasing difficulty increases student motivation and produces more reliable tests. Results indicate that test reliability was largely independent of item sequence. (Author/JN)

Proposed is that the present sequence of algebra followed by geometry leads to frustration. Students should be given the basic skills they need to survive in advanced mathematics and chemistry, with emphasis on percentage and ratio problems. (MNS)

Background information, procedures, and typical results are provided for an experiment illustrating the potential of hydrated salts for solar energy storage. The experiment involves a demonstration often used to illustrate the ease with which some transition metal ions can change their coordination numbers. (JN)

Lists and briefly describes computer programs recently added to those currently available from Project SERAPHIM. Program name, subject, hardware, author, supplier, and current cost are provided in separate listings for Apple, Atari, Pet, VIC-20, TRS-80, and IBM-PC. (JN)

Provides a profile of Michigan high school biology, chemistry, and physics teachers for the 1980-81, 1981-82, and 1982-83 school years, including highest degree(s), major(s), minor(s), sex, years of teaching experience, type of certificate, and assignment(s). Also examines possible trends in the staffing of high school science courses in Michigan.…

This literature review on chemometrics (covering December 1981 to December 1983) is organized under these headings: personal supermicrocomputers; education and books; statistics; modeling and parameter estimation; resolution; calibration; signal processing; image analysis; factor analysis; pattern recognition; optimization; artificial…

Discusses: research and development (R&D) spending by government agencies; federal support for specific areas of R&D; outlays for R&D by the chemical industry and individual chemical firms; manpower in industrial R&D; and sources of R&D funds for universities/colleges. Detailed statistical tables are included. (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)

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)

Describes an interdisciplinary, college-level course on the chemical and physiological properties of selected drugs and medications. The course, which could be adapted for secondary school use, assumes no prior chemical or biological knowledge. Source materials, films used, credit/grading policies, instructional strategies, and course outline are…
