A 100-item five-choice multiple choice (MC) biology final exam was converted to multiple choice true-false (MTF) form to yield two content-parallel test forms comprised of the two item types. Students found the MTF items easier and preferred MTF over MC; the MTF subtests were more reliable. (Author/GK)

Laboratory procedures, equipment, teaching ideas, and resource materials related to physics are discussed. Topics include the construction of a liquid-metal pump, a hydraulic jack, and an apparatus which helps teach time/velocity graphs; current/voltage characteristics of a tungsten filament lamp; and an electric circuit game. (DC)

Introduces a teaching method called guided design which involves a series of problems and solutions with feedback that leads students in a logical sequence through material being taught. Presents 15 worksheets to demonstrate the use of this technique in an introductory ornithology course. (Author/DC)

A biology field course organized to study the effects of the June 1979 Mexican oil spill on the marine biology of the shores of south Texas and Mexico is described, demonstrating how to effectively couple a biology classroom course with a natural or human caused environmental disaster. (Author/DC)

An overview of the role of science and education in society in the People's Republic of China is provided, focusing on agricultural science and research. Topics include the four-level agro-science network, scientists and their social consciousness, and recent changes in educational policy. (DC)

Nine computer programs (available from the authors) are described including graphic display of molecular structures from crystallographic data, computer assisted instruction (CAI) with MATH subroutine, CAI preparation-for-chemistry course, calculation of statistical thermodynamic properties, qualitative analysis program, automated conductimetric…

Compares performance of first-year general chemistry college students from 32 institutions with performance of Advanced Placement (AP) Chemistry Candidates in 1978 to provide a concurrent validity measure of the multiple-choice section of the AP chemistry examination. Average AP candidates scored significantly higher than average college students.…

Presents comments from a symposium at which scientists and science educators agreed that science education should focus more on problem solving and less on mastery of content. Also suggests ways to select textbooks that support a problem-solving approach. (DC)

Presents 15 energy-related physics problems, including a brief indication of the essential features for solving each problem. Problems reflect various energy-related situations and involve different areas of physics. (SK)

Examines the pros and cons of laboratory instruction. Complaints lodged against laboratory instruction include its high cost, and lack of research supporting the lab. Justifications listed include science education research supporting the lab, psychology, and common sense. (DS)

Describes: (1) a variable inductor suitable for an inductance-capacitance bridge consisting of a fixed cylindrical solenoid and a moveable solenoid; (2) long-range apparatus for demonstrating falling bodies; and (3) an apparatus using two lasers to demonstrate ray optics. (SK)

Describes how low-cost audiovisual aids are effectively used at the College of Science Learning Resources Center at Texas A & M University. (HM)

Progress is assessed within the following areas of geoscience education: undergraduate and graduate enrollments, continuing education activities, conferences, National Science Foundation programs, source- and textbook and other educational material publications, earth-science teaching at the precollege level, and marine education (geology of ocean…

Several experiments are described using common laboratory apparatus and readily available materials to generate resonance spectra of air columns. The advantages of this apparatus and method of demonstration are visual impact and accuracy of results. (CS)

Describes advantages and disadvantages of undergraduate research in chemical engineering at the New Jersey Institute of Technology. Also describes a five-year program designed to eliminate disadvantages and complement the graduate program. (SK)
