Presents an activity which helps students investigate how the ocean affects air temperature. Includes temperature data and a map for students to use in plotting and analyzing the temperature ranges of selected cities in Oregon. A supplementary laboratory activity is also offered. (ML)

Describes a set of 10 activities which introduce mainstreamed junior high school students to concepts relating to fossils and dinosaurs. Provides students with opportunities for learning the concepts of change and adaptation, as well as fossil facts and terminology. (TW)

Describes a hierarchical system of problem-solving strategies employed for the solution of a specific kind of problem about speed. Presents the results of 563 high school students tested with problems relating to distance, speed, and time. Provides a rationale for the methods used. (TW)

Describes how computer graphic methods can be used in teaching structural geology. Describes the design of a graphics workstation for the Apple microcomputer. Includes a listing of commands used with software to plot structures in a digitized form. Argues for the establishment of computer laboratories for structural geology classes. (TW)

Describes how mylonite samples can be used to determine the sense of shear. Several sample collection techniques are presented. Criteria for shear sense determination are outlined and discussed so that they can be recognized and interpreted by students familiar with the use of a compass and a petrographic microscope. (TW)

Describes an experiential lab program for a two-year college's chemical technology program. Discusses student experiences in six miniature pilot plants that represent the essential instrumentation and chemical processes found in the chemical industry. Recognizes the industries that helped implement the program. (TW)

Describes a laboratory experiment in which Paramecium caudatum was used to demonstrate the toxic effect of cigarette smoke on the cilia of epithelium cells lining the trachea and bronchi of smokers. Provides background information and explains the procedure, including how to make a simple mechanical smoking device. (TW)

Describes a chemistry laboratory experiment in which thin-layer chromatography (TLC) is used to analyze urine specimens containing metabolites of the drug tetrahydro-cannabinol, which comes from the marijuana plant. The materials needed to conduct the experiment are listed, and the procedure and expected results are outlined. (TW)

Reexamines the traditional role of observation in science and science education. Proposes that since observation is based on some view of the world, it is not innocent and unbiased, but theory-dependent. Discusses possible implications for the science curriculum when reconsidering the role and status of observation in science. (TW)

Offers guidelines for middle and junior high school science education that administrators and/or teachers may use to re-evaluate and upgrade their programs. Addresses concerns related to: special needs of early adolescents, model science programs, model science teachers, materials and resources, and the need for continuing professional…

Describes an investigation of the strategies used by 47 high school students in solving volumetric analysis problems in chemistry. Reports that students in the high ability group mainly used the "formula" approach, while those in the low ability group tended to use the "proportional" approach to problem solving. (TW)

Discusses the value of studying errors made by students in the process of learning science. Addresses 20 research questions dealing with student learning errors. Attempts to characterize errors made by students and clarify some terms used in error research. (TW)

Describes a cooperative program between a school district and local industrial research chemists in which the chemists serve as tutors during after-school hours. Discusses the positive responses to the program in terms of increased student interest, achievement, parental feedback, and the personal gratification of the tutors. (TW)

Reports on a cooperative education program at Montclair State College in which 600 students were placed during the 1984-85 academic year. Describes the techniques used to initiate the program and some of the benefits that the program has provided to the university, the faculty, and the students. (TW)
