Discusses modifications and special equipment needed by wheelchair-bound students for 33 common freshman physics experiments. Physical adjustments, individual needs, and personnel are addressed, with emphasis on building a rapport to learn what a student can and cannot do. A list of modifications for specific experiments (by topic) is included.…

Describes a demonstration in which gaseous ammonia and hydrochloric acid are used to illustrate rates of diffusion (Graham's Law). Simple equipment needed for the demonstration include a long tube, rubber stoppes, and cotton. Two related demonstrations are also explained. (DH)

Describes a one-semester biology course for nonmajors which explores the interdisciplinary potential of psychology, anthropology, history, literature, philosophy, and religion. Satisfactory results in the 1970 tryout with 126 college students are identified. (CC)

Presents an instrumental analysis laboratory section of a problem-based format that includes elements of authentic, investigative, and cooperative learning. Discusses students' attitudes, achievement, and effects of the problem-based instruction on the learning process and higher order thinking in laboratory students. (KHR)

Discusses the use of computers in physics education as a tool in individual student research projects for simulating both simple and more complicated phenomena. Reviews IBM compatible software associated with computer-assisted instruction in physics education. (PR)

Explains that trial and error learning is an important way for children and adults to learn. Open-ended activities have great opportunities for error and eventual feedback for error reduction. (PR)

Describes an experiment where the gram-equivalent mass of an unknown metal is determined by reacting the metal with dilute hydrochloric acid and collecting the evolved gas over water. This simple, reliable experiment routinely gives results within 1% of the accepted value. (PR)

Describes a course that mimics experiences in research laboratories, engages students in collaboration, and reflects trends in educational reform. (YDS)

Investigates the effectiveness of different elements of diagnosis and prescription incorporated into help sessions for college science students. Results show that following laboratory classes with help sessions that are based on the results of diagnostic tests can alter achievement significantly, whether help sessions are directed by teacher or…

Offers an alternative to kymography systems for undergraduates in physiology courses. Explains how an easy-to-build transducer can be used for recording diverse physiological phenomena. Reviews the theory of transducer function and explains the performance of the microcomputer kymography. (ML)

Presents a real life shark attack story and studies arm reattachment surgery to teach human anatomy. Discusses how knowledge of anatomy can be put to use in the real world and how the arm functions. Includes teaching notes and suggestions for classroom management. (YDS)

Presents an experiment to measure the threshold limit of the adhesion of water. Discusses types of thresholds and pseudo thresholds. Provides 13 examples of thresholds in science. (MVL)

Discusses two strategies that provide concrete-thinking students with opportunities to develop and use formal or critical-thinking skills. Describes using task analysis and long-term investigations in the classroom. (YP)

Describes a college course that provides a challenging learning experience in science based upon famous experiments and observations dating from the time of Aristotle to the present day. Presents information concerning (1) the course organization, structure, laboratory development, and expectations; (2) course content by quarter; (3) evaluation of…

Authors discuss how computer laboratory interfacing has revolutionized their nonscience-major introductory chemistry course. Discusses the advantages of doing away with the "cookbook" approach to laboratory experimentation. Presents an evaluation of the course approach including the finding that over 75 percent of the students felt that…
