Described is a collaborative study between a Year 11 physics teacher and 3 university personnel designed to identify and document the manner in which content knowledge was transmitted in the classroom by the teacher and how this knowledge was acquired by students. The role of the textbook is discussed. (KR)

Examined are the type of physics applications that students are interested in learning more about in school. Gender differences within that choice are explored. Interview methodology and the results of the interviews are discussed. (CW)

This paper discusses some of the results of a study conducted in Papua New Guinea on students' comprehension of 45 non-technical words used in science classes. Four words, "component,""devise,""exert," and "random," are considered in detail. (CW)

Described is an extracurricular program for high school students in which they visited a college physics laboratory facility and participated in laboratory activities. Discussed are the planning, student experiences, and results. (CW)

Described are instructional experiences with the use of homemade videofilms. Two particular techniques that can be useful in the production of these films are discussed including the use of chromakey and split-screen. (CW)

A demonstration which illustrates the concept of electric potential using electrophorous is presented. Equipment and procedures for the demonstration are discussed. (CW)

Described are the results of interviews of students regarding the concepts of "forced" and "natural" motion. Aristolean-like beliefs have been found to persist in students even though these views differ from orthodox physics views. (KR)

Describes a method for demonstrating absorption spectra of intensely colored solutions using a mounted grating and a specially designed cell. Allows a student to compare the spectrum of a white light source directly with the same light modified by an absorbing spectrum. Uses acrylic tubing to make the cell. (MVL)

Describes two experiments designed to provide concepts on the difference between heat and temperature and also bond energy. Investigates both a neutralization experiment and a ligation experiment. Notes inexpensive chemicals are used along with simple equipment. Discusses the sharing of lab results for a single class value. (MVL)

Describes 36 science activities. Topics include: osmosis, fermentation, anhydrobiotic organisms, breathing monitors, trypsin, weeds, amyloplasts, electrolysis, polarimeters, ethene ripening of fruit, colorimetry, diffusion, redox reactions, equilibria, acid-base relationships, electricity, power, resonance, measurement, parallax, amplifiers,…

Indicates and describes items that are incorrect in textbooks and a teacher edition of Discover SCIENCE for K-6. (YP)

Describes apparatus for Doppler demonstrations. Provides several pictures of the apparatus and ways it could be used. (YP)

Describes the Soviet educational system and physics textbooks and compares them to their American counterparts. Seventeen references are listed. (YP)

Discusses the equipment and techniques for taking photographs using a sound-actuated trigger. Describes a method using two flash units, two sound triggers, and a high-frequency clock to measure speeds. Provides several high-speed photographs. Lists 11 references. (YP)

Describes the teaching practices of one exemplary physics teacher. Identifies those teaching practices which can be considered exemplary and worthy of attention and analysis by physics teachers and teacher educators. Reports four assertions by the data from observations and interviews with teachers and students. (YP)
