Provides examples of several classroom activities utilizing the American horseshoe crab (Limulus Polyphemus), including raising fertilized eggs, fertilizing eggs in vitro, and testing water samples. Includes background information on the natural history, life cycle, and breeding habits of this animal. (DS)

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Reported is a study designed to: (1) identify the perceived confidence with which perservice science teachers would approach some developmental tasks related to curriculum and evaluation during distinct phases of a year-long course; and (2) compare these perceived competencies to those science supervisors consider important for beginning teachers.…

Describes the Space Shuttle Student Involvement Project which attempts to stimulate high school student interest in science and technology by engaging students in a competition to develop experiments suitable for flight aboard the Space Shuttle. Also describes "Getaway Specials" which allow individuals to send up experiments in the…

Describes equipment, experiments, and activities useful in middle school science instruction, including demonstrating how strong paper can be, the inclined plane illusion, a simplified diet calculation, a magnetic levitator, science with soap bubbles, a model motor and dynamo, and a pocketed sorter for safety glasses. (SK)

Discusses four variables considered to be important at the primary-secondary science interface: (1) the curriculum, (2) the school administration system, (3) the classroom environment, and (4) the teacher. (Author)

States the viewpoints of the Physics Interface Project (PIP) on the core syllabus for A-level physics presented in the May 1980 issue of "Physics Education," including potential problems with the syllabus and its content. Indicates that PIP materials will serve an important complementary function in physics instruction. (SK)

Presents a headmaster's viewpoints and comments on the core syllabus for A-level physics which appeared in the May 1980 issue of "Physics Education," including the necessity for instructional materials, in-service teacher learning, and feasibility studies. (SK)

A university lecturer comments on the importance of adequate detail and individual interpretations of items in the core syllabus for A-level physics presented in the May 1980 issue of "Physics Education." Suggests that the syllabus fails in containing all essential elementary ideas necessary to master advanced concepts. (SK)

Supports the importance of selecting science activities for middle school students that are appropriate to their age level. Lists a variety of resources for science activities, including 11 unit guides, three source books, four journals, and professional meetings. (CS)

Discusses how fifth- to tenth-grade students can be guided to understanding energy as a conserved quantity. Includes examples of different approaches of teaching the energy concept and the concept of energy as a conserved quantity, and learning difficulties related to students' understanding of these concepts. (DS)

Frequently, science fair projects have little relevance to the goals of science. Criteria for judging projects are not evident to students, parents, judges, and other participants. Listed are seven steps to a better fair project which emphasize methodology and presentation. Also included are hints for involving parents. (DC)

Analyzes a study which examined the effects of teacher vagueness on comprehension of high school biology students (N=48) regarding the vascular system of angiosperms. Includes the finding that teacher vagueness terms significantly affect student achievement and student perception of lesson effectiveness. (CS)

A learning cycle involves the active participation of students in exploration, invention, and application phases. Describes one such learning cycle dealing with classification of matter and designed to provide students with an understanding of the terms: atom, molecule, element, compound, solution, and heterogeneous matter. (Author/JN)

Describes the use of microcomputers in data acquisition and simulation of physical phenomena. Discusses digital and analog inputs/outputs, simulations, and interactive programs in mechanics. Includes examples of computer programs. (SK)
