Describes a computer simulation which deals with the Werner-Jorgensen controversy from the standpoint of Kuhn's description of scientific change. Encourages the use of such instructional approaches to introduce general chemistry students to the process of science, including how (1) theories develop, (2) change occurs, and (3) scientists behave.…

Cites studies related to students' misconceptions about the particulate nature of matter. Stresses that a good understanding of these concepts is fundamental to the study of chemistry itself. Reports on a study of preservice elementary teachers views of the particulate nature of matter before instruction on the topic. (TW)

Discusses some of the benefits of having students work cooperatively toward a shared goal. Suggests that teachers become involved in research in this area and become associated with the National Science Teachers Association's Every Teacher a Researcher (ETR) program. Lists various types of research projects teachers could undertake. (TW)

Describes several field activities students can do in a typical woodlot. Focuses on the determination of the amount of lumber (in board feet) available in a predetermined section of a forest. Discusses the use of a Biltmore stick in making simple measurements. (TW)

Describes two courses in chemical safety required as a part of a two-year program in chemical technology offered by the Northern Alberta Institute of Technology (Canada). Lists the topics covered in each course. Provides descriptions of hand-outs, audiovisual materials, demonstrations, assignments, and examinations used in the courses. (TW)

Lists eight sources of technical information suitable for classroom use which deal with polymer materials. Provides the names and addresses of these societies and associations and describes the type of information each has available. (TW)

Contains a set of learning activities which deal with the accelerated loss of the earth's tropical rain forests. Includes four lessons that take 15 minutes or less to teach, background information for the teacher, and a longer lesson which provides an in-depth look at the issues that affect this topic. (TW)

This study of microcomputer use to access an online encyclopedia revealed attitudes of eighth-graders towards computer technology and videotex. Electronic searching is compared to searching with traditional library print materials for a science course, the role of computer printouts is discussed, and research methods including observation and…

Expresses concern over the strain on higher engineering education to keep up with the demand for new engineers. Cites a study conducted to determine whether using currently employed engineers can reduce the burden on engineering schools. Results indicated American engineers are not used extensively in this way. (TW)

Promotes the use of humane education as a vehicle for teaching students how to make bar graphs. Provides ideas for bar graph activities for both primary- and intermediate-grade children that focus on different kinds of domestic and wild animals. Suggests expanded types of graphing activities involving survey techniques. (TW)

Provides perspectives and background information on selected aspects of science instruction. Addresses concerns related to physics teaching, academic assessment, problem-solving, integrated science, readability, college science for pre-nursing students, and a graded assessment scheme. (ML)

Contains a series of activities which focus on the process of extinction, how the increasing human population affects other species, and on the reasons for helping endangered species. Includes diagrams and illustrations of endangered species. (ML)

Discusses the current roles of information technology (IT) in formal education and characterizes emerging trends in the field. Identifies specific uses of computers in physics education and lists representative programs. (ML)

Reports on a study designed to provide a profile of the learning styles of members of the American Chemical Society. Indicates that chemists tend to be more alike than different in their approach to learning. Suggests that chemists tend to be convergers preferring active experimentation more than reflective observation. (TW)

Describes the construction of expert computer systems using artificial intelligence technology and commercially available software, known as an expert system shell. Provides two applications; a simple one, the identification of seven white substances, and a more complicated one involving the qualitative analysis of six metal ions. (TW)
