For colleges/universities, rapid instrument development poses a dilemma, since laboratory teaching instruments rapidly become obsolete and money available for replacing them is dwindling. Discusses role of sophisticated computer simulations, nontraditional educational materials, and part-time work-study opportunities as possible solutions to the…

Describes two- and three-year undergraduate curricula for training earth science technicians at Sir Sanford Fleming College (Canada), emphasizing practical aspects and close student-faculty interaction. List of employment opportunities for geology graduates based on past placement data and geology curriculum outline are provided in tables. (JN)

Suggested guidelines and representative experiments for a one-semester introductory polymer chemistry laboratory course are provided. Experiments, which provide students with both synthetic and characterization experiences, require a minimum of special equipment and student skills. Includes list of 83 experiments, demonstrations, and reference…

Discusses five areas in which chemistry/engineering majors encounter difficulties in technical writing. These include literature searching, plagiarism, organization, synthesis, and rewriting. Also discusses role of technical faculty in helping students solve their writing problems. (JN)

Describes a method for conducting a sophomore organic chemistry laboratory which included integrating projects with a writing task involving peer group interaction. Also includes background/theory, chemistry tasks, writing tasks, and evaluation. Included in appendices are an analytic worksheet and grading scale. (JN)

Reports research into the design and application of physical and mental practice strategies for the development of laboratory psychomotor skills of freshman chemistry students (N=360). Design of instruction materials used (focusing skills using balance, pipet, and buret and skills in quantitative volumetric analysis), evaluation of strategies, and…

Provided in two separate annotated lists are technical and nontechnical astronomy books. Categories in the latter group include: general astronomy; astronomy textbooks; amateur astronomy; astronomy history; life on other worlds; astrophysics; the solar system; space exploration; and the sun. (JN)

The earth's oceanic crust is created and destroyed in a flow outward from midocean ridges to subduction zones, where it plunges back into the mantle. The nature and dynamics of the crust, instrumentation used in investigations of this earth feature, and research efforts/findings are discussed. (JN)

Discusses the earth's biosphere, considering how the microbial, animal and plant life (which make up the biosphere) are sustained by the earth's lithosphere, hydrosphere, and atmosphere. Also considers how these three earth features have powerfully shaped the evolution of these organisms. (JN)

Because voltage is a difficult concept to comprehend, it is expected that textbook authors would be clear/consistent in their presentation. Presents 11 examples in which the concept is explained or used (taken from one book), suggesting that the presentation makes it difficult for students to develop an understanding of voltage. (JN)

Describes a field trip designed to give students opportunities to experience relevant data leading to concepts in biogeography. Suggests that teachers (including college instructors) adapt the areas studied and procedures used to their own locations. Includes a suggested field trip handout. (JN)

Investigated relationship between students (N=1008) preparation in high school physics/chemistry and success in college chemistry as measured by a final letter grade of B- or better. Results indicate that most well-prepared students (defined as having had previous experience in chemistry, physics, and mathematics) do well in general college…

Describes a three-part experiment designed to introduce cyclic voltammetry to graduate/undergraduate students. Part 1 demonstrates formal reduction potential, redox electron transfer, diffusion coefficient, and electrochemical reversibility. Part 2 investigates electrochemical behavior of acetaminophen. Part 3 examines such experimental variables…

Discusses various physics concepts/principles that can be illustrated by amusement park rides. Examples of rotational dynamics, energy conservation, acceleration, and others can be demonstrated by such rides as roller coasters, Ferris wheels, and a variety of rotating rides. (JN)

Describes two kinematics/dynamics programs (Apple II) easily adaptable to other microcomputers. Kept simple, the programs allow teacher/student to control forces acting on a particle by introducing force laws in programs or by using game paddles/joystick. Discusses equations used and provides program listings. (JN)
