Examines if a self-paced, interactive microcomputer delivery system can decrease the time needed and improve the level of mastery as compared with a traditional self-paced instructional approach. Uses high school physics students with five activities and reports that no differences were found. (MVL)

Compares a program written both in BASIC and LOGO on its inferential and decision making ability. Explains steps in each program and how deductions and decisions are made. (MVL)

Presents teacher comments on audiovisual materials dealing with: biotechnology applications in immunology, agriculture, and cancer research; efforts to halt the eutrophication of Lake Tahoe; and banana slugs. Availability and costs of materials are included. (RT)

Discusses changes made since the publication of "A Nation at Risk." Presents a chemistry course in which scientific literacy is a major emphasis. Provides methodology for the course and a listing of the topics for instruction. Notes several criticisms of the approach. (MVL)

Discusses a survey of selected undergraduate chemistry laboratory courses. Topics include: who preps the experiment; degree of faculty involvement; instructional loads; types of directions used; satisfaction with materials used; techniques taught; computer use; rating the laboratory; and a self rating. Provides data for each topic. (MVL)

Describes several common synthetic organic transformations involving alkenes, alcohols, alkyl halides, and ketones. Includes concepts on kinetic versus thermodynamic control of reaction, rearrangement of a secondary carbocation to a tertiary cation, and the effect of the size of the base on orientation during elimination. (MVL)

Argues that there are five domains of science education: knowing and understanding, exploring and discovering, imagining and creating, feeling and valuing, using and applying, and not just the two domains of content and process which many people view as being science. (RT)

Presents a lesson on introducing writing into the science curriculum by using an experiment to illustrate the detrimental effect of tobacco smoke on human lungs. Outlines the materials, procedures, a summary of the project, extension activities, and additional information about the writing process. Two handout sheets are included. (RT)

Discusses a continuing education course that reached 1000 viewers at 43 North American sites. Points out that each professor had 35 minutes for his presentation followed by a 10-minute call-in question and answer period. Notes polymer topics will be the focus of upcoming lessons. (MVL)

Described is an experiment in which the student can ascertain the meaning of a negative result from a qualitative test by performing a more sensitive quantitative test on the same sample. Methodology for testing urinary glucose with a spectrophotometer at 630 nm and with commercial assaying glucose strips is presented. (MVL)

Presents an example of a greenhouse-effect experiment from the Climate Protection Institute. Analyzes the amount of carbon dioxide in ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide by titrating with ammonia and bromthymol blue. (MVL)

Discusses the lack of study skills found among non-science majors. Provides examples of how science courses differ from other courses. Gives some methods to help students study more effectively. (MVL)

Uses a method which involves weighing out an amount of the appropriate weak acid or base and dissolving it in distilled water close to the final volume. Solution is then titrated with strong acid or base to give the desired pH. Provides three examples. (MVL)

Describes a laboratory experiment to teach the principles of air sampling, gamma ray spectroscopy, nuclear decay, and radioactive equilibrium. Analyzes radon by carbon adsorption and gamma ray counting. Provides methodology and rate of decay equations. (MVL)

States that if photochemical reactions can be followed spectrophotometrically, reactivities can be estimated by evaluating data from only one curve. Studies such a system using computerized evaluation and simulation. Uses chlorocuprate(II) complexes in acetonitrile solutions for the model systems. (MVL)
