Points out a misconception that is reinforced in many elementary and advanced chemistry texts. Discusses the general limitations of the orbital concept. Notes misconceptions related to the transition elements and their first ionization energies. (MVL)

Presents a rationale for adopting a client-centered approach for foreign language teacher development programs. An inservice English-as-a-second-language teacher education workshop in Adelaide (Australia) helped participants to select and grade learning tasks. Participants then incorporated the "good" learning tasks into their own…

Reviews how background knowledge fits into a model of the expository writing process. Describes a project involving gifted seventh-grade students who increased their background knowledge about their chosen research paper topics in order to overcome some of the difficulty of expository writing. (RS)

Described and assessed was the teacher's role in three elementary school science programs which included hands-on learning experiences for the students. Results indicated that this role varied with the manner in which hands-on materials were used in the program. (CW)

An overview of the current status of Chinese language instruction in the United States focuses on trends in enrollment, interest in foreign language study, relevance of the less commonly taught languages, and instructional methods and materials. Solutions to long-standing problems in Chinese language study are included. (CB)

Provides guidelines for a custom-made science program that integrates science, math, and technology. Describes the curriculum which is divided into themes including the applied sciences, cycles of the universe, plate tectonics, rock, water, and life. (Author/RT)

Discusses the importance of implementing new approaches in science teaching which will elevate citizen concerns to science-related issues confronting society. Outlines a biology application course designed to counteract current problems in this area. (RT)

Presents several fun activities and teacher demonstrations which simplify terms and condense science concepts for teaching about the lever, wedge, wheel and axle, screw, pulley, and the inclined plane. Includes objectives, materials, procedures, suggested follow-up assignments, and diagrams. (RT)

A course for life science and social science students at Hampshire College is a combination of mathematics and computer science. Through actively involving students in manipulations and simulations, their appreciation for the logical and aesthetic properties of mathematical tools and their capacity for the independent work is enhanced. (MLW)

Summarizes the findings of studies that indicate serious deficiencies in the reading, writing, and basic information skills of American students. Possible causes are discussed including the lack of effectiveness of teaching methods and instructional materials. It is argued that the school library offers the best hope for creating a culturally…

Discusses several issues important to chemistry: enticing top-notch students into the discipline, keeping up with the tremendous growth of chemical information, and promoting chemistry to the general public. Suggests eight methods to answer these issues. (MVL)

Presents a method to teach stoichiometry where a problem is broken down into four factors and two cycles. Offers grams of known, moles of known, moles of unknown, and grams of unknown as the factors. Uses factor labeling as the second cycle. (MVL)

Described is an introductory laboratory course designed to enhance basic skills required of biology majors. Discusses materials and their development, manual design, and student and instructor's roles. Outlines procedures and examples of writing, reading, and mathematics activities. (RT)
