This guide contains 19 science-based, multidisciplinary activities that teach what a watershed is, how it works and why we must all consider ourselves watershed managers. An extensive background section introduces readers to fundamental watershed concepts. Each activity adapts to local watersheds, contains e-links for further Internet research and…

Initial textbook investigations indicate that more new words/phrases are introduced than in a similar time frame in which foreign languages are studied. Reviews these initial studies, studies of vocabulary mastery in foreign languages, and general research concerning vocabulary development. Reports on occurrence of technical/special words in 25…

Discusses responsibilities for providing safe experiments and for teaching about safety. Provides lists of references on chemical safety and regulated/potential carcinogens. Also discusses general laboratory safety procedures including waste disposal and recycling of solvents. (JM)

Examined students' conceptions of the words "force" and "energy" using the interview-about-instances approach. Implications for science instruction and instructional strategies are discussed based on findings that many students have views of these concepts that are different from accepted scientific views. (JN)

Discusses the nature of naive conceptions and the influence of these conceptions on students' interpretations of instructional events. Also discusses implications of this research for designing instruction to facilitate the reconciliation of naive conceptions with scientific theories. (JN)

Provides geology departments and science educators with a leadership model for developing earth science inservice programs. Model emphasizes cooperation/coordination among departments, science educators, and curriculum specialists at local/intermediate/state levels. Includes rationale for inservice programs and geology department involvement in…

Teacher training for Guyanese secondary science teachers in a school of education was compared with a distance-taught program by a variety of criteria: supervisor scoring using the Guyanese Ministry of Education's rating scale in classroom observation; self-ratings pupil ratings; and ratings by head teachers in schools having graduates of both…

Investigated importance, according to teachers (N=257), of a validated list of 10 aims for school practical work at three grade levels. Also investigated the orientation of students (N=724) toward these same aims (expressed as influences) and compared aims for teachers with influences as perceived by students. (Author/JN)

Audiovisual methods used in an analytical chemistry course covering the theory related to six instrumental analysis techniques are described. Evaluation through student surveys indicates that the methods are good substitutes for conventional lectures. (SK)

Presents procedures, experiments, demonstrations, teaching suggestions, and information on a variety of chemistry topics including, for example, inert gases, light-induced reactions, calculators, identification of substituted acetophenones, the elements, analysis of copper minerals, extraction of metallic strontium, equilibrium, halogens, and…

Presents ideas to promote higher-level thinking in general chemistry classrooms/laboratories, focusing on applications of Patricia E. Blosser's taxonomy to enhance students' convergent/divergent/evaluative thinking. Compares Blosser's taxonomy with Bloom and Piagetian taxonomies, suggesting a combined Blosser/Piagetian taxonomy to achieve goals of…

Effect of science instruction on young children's (N=64) concept of Piagetian physical causality was investigated. Results indicate, that pre/concrete-operational children can learn and apply a definition of living when that definition is taught through observable characteristics. Additional results and implications for elementary science…

Fourteen papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are summarized. Papers focused on secondary/college chemistry courses, programs, instructional strategies, and projects emphasizing the relationship of chemistry to "real world" problems and issues. (JN)

Forty-five "poster session" papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are highlighted. These papers focused on computers in chemistry and chemical education (emphasizing programs) and on instructional innovations (including courses, teaching methods, testing, experiments, and others). (JN)

Describes a two-semester laboratory program designed to motivate students. The program consists of computer-oriented modules and discovery approach laboratory exercises. Students complete similar computer/laboratory material during the first semester but elect one of three tracks during the second semester (computer, every-day life, and…
