Describes a spectrophotometric titration experiment which uses a manual titration spectrophotometer and manually operated buret, rather than special instrumentation. Identifies the equipment, materials, and procedures needed for the completion of the experiment. Recommends the use of this experiment in introductory quantitative analysis…

Describes an experiment that demonstrates the use of HPLC in simultaneous multi-element analysis. Discusses the application of this process in identification of steels and trade effluents. (TW)

Describes a physical chemistry experiment which uses spectroscopy to measure the heat of formation of Na2SiF6. Discusses the opportunities for students to see the use of a familiar instrument in an unfamiliar application, emphasizing that there are often many ways to attack problems in science. (TW)

Describes apparatus for use in high school chemistry instruction. Provides instructions and lists of materials needed for building a homemade sand bath for use in experiments that demonstrate the slow evaporation of a solvent. Plans for the construction of a low-cost conductivity apparatus are also included. (TW)

Discusses a recent addition to the Museum of Science and Industry (Chicago) known as "Everyday Chemistry." This permanent exhibit on modern chemistry incorporates demonstrations of chemical reactions in ways intended to enhance public understanding. Describes the six cases in the exhibit and the automated aspects of their demonstrations.…

Explains the functions of and the techniques employed in expert systems. Offers the program "The Periodic Table Expert," as a model for using artificial intelligence techniques in BASIC. Includes the program listing and directions for its use on: Tandy 1000, 1200, and 2000; IBM PC; PC Jr; TRS-80; and Apple computers. (ML)

The chemical content knowledge of secondary science teachers is seldom measured directly in developed countries as there are practical, ethical and political problems involved that would be likely to be insuperable. In Papua New Guinea (PNG), the author assisted in some of the work involved in the second IEA Science Study (SISS), where the PNG…

As colleges and universities nationwide anticipate enrolling more than two million new students over the next decade, UC Berkeley is exploring options for serving more students, more cost effectively, in large lecture courses. This research project analyzes economic and pedagogical questions related to the use of on-line lecture and laboratory…

This is a two-part curriculum package for the teaching of chemistry and the periodic table. The first part, the Teacher's Guide, contains information necessary for using the equipment in a typical classroom including learning goals, vocabulary, math skills, and sample data for each activity. The second part of the package consists of photocopy…

Reviews educational computer games, tutorials, and drill/practice programs for Atari and Apple microcomputers. Includes: games/nursery rhymes for pre-schoolers; graphics, word scramble, and vocabulary programs; mathematics programs (fractions, reading/solving mathematics problems, estimating angles/lengths); science (chemistry, weather, astronomy,…

Provided is a list of educational software arranged alphabetically by manufacturer. Entries include name, system requirements, current cost, and a brief description. A wide variety of subject areas, educational levels, and formats (drill/practice, games, tutorials, and others) are included. (JN)

Reports on research and development (R&D) spending and manpower, emphasizing R&D in chemistry and chemical engineering. Data are presented in tables and graphs related to the federal government, industry, universities and colleges, and a total look at United States R&D efforts. (SK)

Presents laboratory procedures, classroom materials/activities, and demonstrations, including: vapor pressure of liquid mixtures and Raoult's law; preparation/analysis of transition metal complexes of ethylammonium chloride; atomic structure display using a ZX81 (includes complete program listing); "pop-up" models of molecules and ions;…

Results are reported of performance and attitudes of students (N=109) receiving high structure (objectives, reviews, examples, questions, feedback) and students (N=108) receiving low structure (emphasis on content) laboratory manuals and instructions. (SK)

Information is presented, based on two visits to the USSR combined with a reading acquaintance of Soviet science education, about education in science in Soviet schools. (PB)
