Argues that biology teaching at its best is characterized by students acquiring scientific, creative, and critical-reasoning skills. Advocates the use of case studies as an alternative approach to investigative laboratories. Contains 23 references. (DDR)

Explains the nature and scope of Operation Pathfinder which involves teachers in a two-week course characterized by hands- on experiences with coastal processes and oceanographic research. (DDR)

Discusses the characteristics and benefits of the Nebraska Operation Chemistry (NOC) summer workshops. Provides a brief overview of the workshops and the 11 instructional modules. (DDR)

Focuses on mapping activities designed to provide simulated experiences that help students understand the techniques used to measure and represent underwater terrain without making direct visual observations. (DDR)

Discussion of the use of manipulative materials in kindergartens focuses on a new generation of computationally enhanced manipulative materials, called digital manipulatives, designed to allow all students to explore mathematical and scientific concepts through direct manipulation of physical objects rather than more abstract methods of learning.…

Discusses an approach to the first day of general chemistry class that utilizes principles of constructivism, collaborative and cooperative groups, and student-centered learning. (CCM)

Analyzes changes and developments in the primary science curriculum in Botswana from 1969-1989. Discusses the objectives, basic concepts, and reasons for change during three time periods: 1969-1982, 1982-1989, and 1989-present. Identifies discovery teaching as the recommended method of instruction. (Contains 17 references.) (Author/YDS)

Focuses on inquiry-based science instruction for third grade elementary school students. Presents an activity on analyzing data using a graph. Explains what students learn from inquiry-based instruction. (YDS)

Discusses a college science course designed for juniors and seniors who are going to be elementary teachers. Focuses on hands-on activities, understanding the nature of science, and conducting scientific research. Explores student misconceptions and conceptual changes on elementary science subjects. (YDS)

Presents a set of hands-on electrostatics experiments in the form of an activity guide and worksheet through which students discover the different types of electric charge, Coulomb's Law, induced charge separation, and grounding. (DDR)

Illustrates the use of learning contracts with students involved in science projects. For the learner, the contract is a worksheet to help plan the project as well as an agreement that outlines the tasks to be performed. (DDR)

Announces the theme for National Science and Technology Week (NSTW) 1998 and offers a rationale for the choice of the topic of polar connections. Suggests that the poles offer a glimpse of science as high adventure. The poles are often seen as pristine, nearly lablike environments that provide a platform for animal studies. (DDR)

Presents an open-ended project tailored for a senior kinetics and reactor design course in which basic reactor design equations are used to model the digestive systems of several animals. Describes the assignment as well as the results. (DDR)

Describes how interaction with several polymer manufacturing companies through industrial short courses and research projects has led to the development of dynamic and up-to-date undergraduate and graduate curriculums in polymer science and engineering technology. (DDR)

Presents three activities to teach elementary students about why magnets stick to some things but not others. The activities have students discover what makes materials magnetic, what the lines of force are in a magnetic field, and how magnetic forces penetrate materials such as paper and cardboard. (SM)
