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)

Discussion of changes in science education and scientific literacy is presented in the form of a dialog between the author and his alter ego. Structure of science, myths, facts, methods, and critical rationality are considered. Suggests that scientific principles once considered basic and unchanging are giving way to critical thinking. (DH)

Contemporary philosophy of science is controversial and includes debate about the relativity of scientific knowledge and the rationality of scientific enterprise. Crucial questions and important ramifications for science education are presented through discussion of these philosophical disputes. (DH)

Urges biology teachers to discuss creationism in classrooms, pointing out why it is not science. Indicates that such action would be farsighted recognition of and response to a genuine educational need in society. Topics addressed include scope of science education, the creation movement, censorship, and suggestions for implementing creationism in…

Discusses how "live" experiments were combined with media packages and recorded lectures to allow coverage of more material and foster greater student/teacher interactions. Notes were distributed at the beginning of the semester which allow students to record experimental data from class demonstrations. Problems and suggestions for course…

Presents a simple, 10-item quiz designed to make students aware that they must learn laboratory safety. The items include questions on acid/base accidents, several types of fire extinguishers, and safety glassses. Answers and some explanations are included. (DH)

Latent image processing is a method which reveals hidden ink when marked with a special pen. Using multiple-choice items with commercially available latent image transfers can provide immediate feedback on take-home quizzes. Students benefitted from formative evaluation and were challenged to search for alternative solutions and explain unexpected…

Student interest was stimulated and critical thinking skills developed through an "Issues in Social Biology" course which include several topics in genetics. Judicious selection of topics, course format, and ordering of subjects are discussed, along with suggestions for course improvement development. (DH)

Federal parks and monuments are numerous, widespread, and offer unique opportunities for funded research and employment for science undergraduates. Elements essential to quality undergraduate research, contacts, research needs, and funding are discussed, along with description of a successful undergraduate field research program in Missouri. (DH)

Telephone equipment and television monitors allow university faculty to provide high-quality physics courses for secondary students. Equipment, technology, and course format for this remote site instructional program are discussed. Results indicate differences in small versus large school, but participants believe the project offers a solution for…

Shows how the natural membrane of a decalcified chicken egg can demonstrate the principle of osmosis within a single class period. Various glucose and saline solutions used, periods of time, physiological effects experiments, and correction for differences in initial weights are noted. (DH)
