Explains the rationale and goals for a physical science course for elementary education majors. Components include: presentation of a science lesson from one of the elementary science programs; hands-on experience with lessons taught by other students; and incorporation of current science-technology-society problems into discussions. Results from…

Outlines steps to generate cell samples for observation and experimentation. The procedures (which use ordinary laboratory equipment) will establish a short-term primary culture of normal mammalian cells. Information on culture vessels and cell division and a list of questions to generate student interest and involvement in the topics are…

Discusses the need for students to develop understanding of science by designing their own laboratory experiments. Lists examples of concepts that can be taught through student-designed biology experiments. Also gives suggestions and guidelines to ensure that laboratory time is manageable and productive. (DH)

Discusses the need for preservice elementary teachers to experience inquiry first-hand, suggesting that they engage in problem-solving rather than just "talking about" it. A typical teacher education program is described with suggestions to incorporate inquiry-oriented experiences. An inquiry-oriented activity using sand and funnels is included.…

Advantages for using 35mm slides to enhance a lesson rather than more expensive films and videotapes are considered. Includes information on: negative (black-on-white) slides; highlighting and opaquing; positive (black-on-white) slides; and white-on-colored background. Suggestions for film types and developing procedures are given. (DH)

Explains: (1) the "standard" atmospheric pressure demonstration using an empty duplicating fluid can and heated water; and (2) a variation of this demonstration using an aluminum soft drink can. (DH)

Describes a course which examines the history and philosophy of the relationship between science and society and applies these concepts to such current issues as sociobiology. Includes course outline, instructional strategies, and bibliography of pertinent books, papers, and lecture notes. (JN)

Examines various aspects of and issues related to falsifiability, a standard criterion for identifying true scientific systems. Also proposes a simple new standard for evaluating a scientific theory. (JN)

A Michigan State University committee examined major problems and issues confronting precollege science educators at national and state levels. A summary of these problems and issues is presented, along with specific recommendations for action in the state of Michigan. (JN)

A division of chemical education has been created within the chemistry department at Purdue University. The nature of chemical education, impediments to research and development in chemical education, and future directions of the division are discussed. (JN)

Describes science activities which have been successful with nonscience majors. Each activity requires students to make observations, record the data gathered, interpret data, and prepare a written report. Subject areas include motion of stars, sunspots, lunar orbits, sunset points, meteor showers, and sun shadows. (JN)

The microcomputer used as a closed-circuit television typewriter and graphics generator is suggested as an alternative visual teaching strategy for lecture or discussions. The use of such a system in an introductory biology course for nonmajors is discussed. (JN)

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)

Describes a system in which organic chemicals are recoded for inventory control and reshelving purposes. The system works well in undergraduate organic chemistry or biology laboratories but can be expanded to handle a larger and more complicated inventory. (JN)

Outlines various misconceptions about problem-solving (PS) and several strategies to improve intellectual skills and strategies. Also describes the Covington Productive Thinking Program (designed to help develop PS skills) and several lesson problem sets from this series of 15 books. (JN)
