A description is given of a chemically-oriented curriculum on "Smoking and Cigarette Smoke" for science and nonscience oriented high school students. Laboratory activity is emphasized. (SA)

This is a set of recommendations concerning maximum teaching loads of physics teachers at high schools, two-year and four-year colleges. (Author/SA)

Several potential safety problems are identified relative to science teaching: the use of bottled gas or alcohol lamps as heat sources, the hazards of Millon's Reagent for testing for proteins, and the use of silicon tetrachloride to demonstrate properties of chlorides. Science teachers are also warned about potentially dangerous procedures…

Evaluates an educational program carried out at the Institute for Desert Research in Israel, to test the possibilities of the desert as an educational resource for ecosystem study. The results of teaching a field-oriented ecology course are presented. (HM)

Investigates the abilities of 36 fifth graders and 30 ninth graders who were selected from 11 schools in Thailand to solve problems involving seven of Piaget's logical operations. These operations are classification, seriation, logical multiplication, compensation, proportional thinking, probability, and correlational thinking. (HM)

Details a summary presented by a distinguished high school chemistry teacher at the close of the symposium on the High School Instruction Interface dealing with the modernization, restructuring, and improvement of chemistry teaching. (BT)

Presents the results of an investigation to determine if the position of a distractor in a multiple choice question influences the degree of difficulty of an item. The data support the hypothesis that the placement of the distractor immediately before the key alters the difficulty of the item significantly. (Authors/SA)

The use of live animals in the secondary school laboratory is discussed along with suggestions for increasing the use of live animals and challenges to those teachers who restrict this use. (SA)

Explores the patterns of responses of a population of high school students on an opinionnaire about energy-related matters. The sample consisted of 413 students, grades 10-12, in a school system in the southeastern United States. (HM)

Used data from the Baccalaureate and Beyond study to examine different paths to teaching grades 6-12 math and science taken by recent U.S. college graduates and differences in experiences and commitment toward teaching. Only 46.6 percent of new teachers were minimally qualified. Those with math or science certification were most likely to be…

Investigated the effects of science lessons, framed as persuasion, on middle school students' knowledge, beliefs, and interest. Students received participated in teacher- or student-led lessons. Their knowledge, beliefs, and interest were compared to those of students in other science classes. There were significant differences between persuasion…

Described is an extracurricular organization for future science teachers at the undergraduate level. The formation, activities, and service projects of the group are discussed. The benefits of this type of group to preservice science teachers is stressed. (CW)

Presented is an analogy that can be used to explain the particle theory of matter. The three phases of matter are represented by preschoolers, yuppies, and senior citizens. The value of using analogies is discussed. (KR)

Presented are 10 intervention techniques for making science a hands-on experience for disabled students. Included are field trips, lab buddies, flexible rooms, customized lab equipment, lesson adaptation, precourse interviews, involving the class, computer-assisted learning, social considerations, and the team approach. (KR)

Discussed is the idea that models should be taught by emphasizing limitations rather than focusing on their generality. Two examples of gas behavior models are included--the kinetic and static models. (KR)
