Summarizes what is known about the effects of marijuana use on health. The topics included are its chemistry and the metabolism; the effects of acute intoxication on learning, memory, intellectual performance, driving, and other skilled performances; and effects on lungs, brain, heart, and other systems. (SA)

Discusses the development of science programs for Australian secondary school students of year 11 and 12. A modular science syllabus which has been developed in New Zealand and some examples of how some Australian schools have devised unified science programs are also discussed. (HM)

Discusses the use of formulae in the teaching of chemistry as part of the individual culture and of the conceptual structure of chemistry. A historical viewpoint on the procedures for structure representation and some educational implications for teaching chemistry in Italy are also presented. (HM)

Included are suggestions for ways to incorporate the teaching of language skills into middle school science courses. Listed are communication skills that overlap in English and science. Grading methods and writing assignment topics are described. (CS)

Tests the immediate and delayed effectiveness of an instructional module, "Levels of Questioning," designed to improve the level of preservice science teachers' questions. Results indicate that the module was effective in raising the average question level but that skills were not retained. Recommendations are made for revision of the module. (CS)

Presents seven selected biology notes which could be used in the school biology courses. Each includes the name of the author and a description of activities suggested. (HM)

Describes a technique for the laboratory culture of Eucyclops agilis using Euglena. Details of the life cycle are given, and suggestions for its use in laboratory practicals, and in investigations with sixth-form (16 to 18 year-olds) and college students in the United Kingdom. (Author/HM)

Describes a laboratory demonstration in chemical equilibrium using ferric chloride and ammonium thiocyanate that would serve as a useful basis for an inquiry investigation. (BT)

This review of 11 recent science kits, texts, supplements, and series for various grade levels, K-12, includes a special section examining three junior high level texts on the subject of light. (SJL)

Suggestions are given for dealing with "senioritis" in high school students. These include offering college-level courses at a reduced cost. A description of introducing the college freshman biology course at Syracuse University into a high school program is given, with guidelines to promote success. (Author/SA)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

Describes how small-mammal studies in the out-of-doors can be adapted to science and environmental programs in the middle and upper secondary grades. (HM)

The approach described in this article represents a combination of teaching techniques that were successful for a high school biology teacher. The process is described as shared decision making and the student becomes an active partner in the learning process. (Author/SA)

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

Presents a summary of the findings of three national studies sponsored by the National Science Foundation in 1978 on the status of science, mathematics, and social science education in the nation's elementary and secondary schools. This report deals only with science education. (HM)
