Describes research seminar class offered to juniors/seniors at Cy-Fair High School in Houston (Texas). Students do literature search, select research topic, make a proposal which is critiqued by students/teachers, conduct research, write a paper based on the literature search which incorporates the results of research; and give oral presentations.…

Suggests two methods of developing the study of the noble gases: first, the discovery of the elements and recent discovery of xenon show the human face of chemistry (historical development); second, the properties of noble gas compounds (particularly xenon) can be used to test the framework of conventional chemistry. (Author/JM)

Discusses the realities of implementing a computer-assisted program in high school level science classes, offering some practical suggestions for making such a program successful. Also includes information on several software packages for interfacing microcomputers to sensing equipment. (JN)

Describes "The Kinetic Karnival of Jearl Walker," six 30-minute television programs. Programs focus on: forces/collisions; rotation; fluid flow and friction; viscosity; Leidenfrost effect; and the science of cooking. Teacher's manual containing description, class preparation, questions, and bibliography are provided with each program (available in…

Ferns in culture provide versatile and easily manipulated material for a wide variety of experiments and observations. Information is provided that supplements earlier reports of the vast experimental potential of these cryptogams and outlines laboratory exercises which reveal the regenerative behavior of fern tissue. (JN)

Develops the question of evaluating energy education programs' direction/progress in light of four goal custers identified in the National Science Foundations' Project Synthesis. Discusses important characteristics of energy education curricula using transporation as an example. Urges establishment of learning environments in which students can…

Since 1977, six different classes of Ashland High School (Ohio) biology students have been monitoring a local river for the presence of sewage treatment plant effluent. Several project results, physicochemical parameters, and data on biota collected at two stations are presented. (JN)

Whether you're a stream studies novice or a veteran aquatic monitor, "Watershed Dynamics" gives you abundant practical resources to extend your students' investigations into local water quality and land-use issues. This two-part set is ideal for teaching biological and ecological concepts and research techniques. It also shows how the interplay…

This study compared science students' perceptions of their teacher-student interactions with those of their teachers by administering the Questionnaire on Teacher Interaction (QTI) to teachers and students in 80 lower secondary science classes in two Australian states (Tasmania and Western Australia). There are three versions of the QTI: the…

Describes an interdisciplinary, month-long minicourse project focusing on the gypsy moth. The project provided students with opportunities to develop analytical and problem-solving skills while studying content from entomology, botany, chemistry, toxicology, ecology, math, art, law, political science, history, English, consumer studies, and…

Evaluated teaching activites focusing on scientific concept of "animal" with three age groups: 5 (N=15), 9/10 (N=23) and 14 (N=20). Results suggest that these activities modified some students' concept of "animal" toward the scientific one, and that not understanding basic concepts (such as animal) may cause difficulties in…

Describes equipment for recording human breathing (stethographs, tambors, spirometers), construction of pooters (pipettes), field exercise on examining epiphyte distribution on tree bark, and vertebrate skeleton models for teaching locomotion. Includes abstract of student research project examining pH on Colpoda encystment and reviews of…

A 20-item double-Q sort was used to measure differences in perceptions of grades 8, 10, and 12 students (N=215) according to letter grades and sex. Differences in perception according to success were found for both ideal and actual student behavior, while sex differences were not noted. (Author/JN)

Investigated 90 Form Two students' (grade nine equivalent in USA) alternative conceptions and instructional strategies to affect change from alternative to scientific conceptions. Results indicate significantly larger improvement in acquisition of science concepts (mass, volume, density) by experimental groups resulting from strategies/materials…

Two copy-protected chemistry simulations (for Apple II) are described. The first demonstrates Hess' law of heat reaction. The second illustrates how heat of vaporization can be used to determine an unknown liquid and shows how to find thermodynamic parameters in an equilibrium reaction. Both are self-instructing and use high-resolution graphics.…
