Describes a quantitative evaluation of an interactive videodisc program in which students measure the temperature dependence of the solubility product of lead chloride by titration of chloride with silver nitrate using a Mohr titration. Student reaction (based on responses made using the program, quiz answers, and laboratory performance) was…

As an alternative to traditional science projects, students in introductory organic and inorganic chemistry were given the opportunity to produce an "audiovisual" term paper. Rationale for the project, responses from student self-evaluation questionnaires, and comments on implementing the project (including cost and time factors) are…

Compared the effectiveness of using guided-design or traditional approaches to study the energy problem in America. Examined to what extent students: (1) actually learned material; (2) perceived they learned the material; and (3) became more involved in discussing and considering solutions to energy problems. Includes course and guided-design…

Discusses Cuban medical facilities, biological research (focusing on sugarcane tissue culture, interferon, hybrid cattle, tropical fruits, and yeast biosynthetic pathways), science education programs at all levels, and institutions of higher education. Also examines such concerns as the Cuban literacy rate and efforts to improve the environment.…

Presents an appendix to the Committee on Professional Training (CPT) of the Division of Chemical Health and Safety of the American Chemical Society. The information is applicable to chemical health and safety policies and practices within the chemistry department of an academic institution. Includes lists of references with safety information. (JN)

Chemistry students selected a main group of the periodic table, researched the group, and then presented a 70-minute lecture on the group; conducted two lecture demonstrations; and performed two laboratory experiments. This was done to determine what descriptive chemistry should be included in a new sophomore-level inorganic chemistry course. (JN)

Describes a program designed to prepare students to work upon graduation in the industrial chemical field as chief chemists in production plants; in analytical laboratories; or in sales, management, or public relations within chemical firms. Also describes industry-college relationship established to achieve program objectives. (JN)

Describes current methods for the synthesis of DNA. Also describes the use of DNA as a highly specific molecular probe and as an agent for the mutation of genes. (DH)

Describes a course in which students examined the social implications of biological research, discussed the individual's role in research and whether there is an honor code of science, and completed a simulation which involved private companies competing for a government research grant. Instructional strategies used with the exercises are…

A program (written in Microsoft BASIC) for the Texas Instrument and IBM microcomputers allows one to eight contestants to select one to six categories of questions to answer in the manner of the game Trivial Pursuit. The structure, use, and educational value of this program are reviewed. Ordering information is included. (JN)

Describes an experiment designed to help students understand the concepts of osmosis and surface area to volume ratio (SA:VOL). The task for students is to compare water uptake in different sizes of potato cubes and relate differences to their SA:VOL ratios. (JN)

If sciences were taught as truly liberal arts, part of the trend toward scientific illiteracy could be reversed, with one result that students could leave college with an appreciation for and understanding of the scientific approach to knowledge. Liberal arts science courses should be conceptually rigorous, mathematically attainable, and…

Describes various ways a user can control computer program activity using different menu constructions. Advantages, disadvantages and program design principles for menu design are discussed. A listing for a menu demonstration program is included. (BC)

Advantages and disadvantages of using multi-image or lap-dissolve (LD) slide techniques in large lecture sections are discussed. Production, use, and evaluation of LD programs are also discussed. Indicates that these programs are an effective way of improving instruction on visually oriented topics. (JN)

Background, procedures used, and typical results are provided for an experiment in which students carry out the necessary measurements on the acid-catalysis of penicillin in two hours. By applying kinetic theory to the data obtained, the reaction pathways for the hydrolysis of potassium benzyl penicillin are elucidated. (JN)
