This study was designed to simulate some aspects of classroom verbal interaction and to investigate their cognitive effects on students, using cognitive theory as the theoretical rationale. Subject-determined verbalization of correct cues was crossed with external sources of verbalized correct cues in a multivariable design in which sex was…

The teacher's edtion for the Intermediate Science Curriculum Study Level III unit entitled "Winds and Weather" provides instructions for teachers for examining some principles underlying thermal convention, weather observation, closed systems, moisture and cloud formation, the heated-air model, and fronts. A brief introduction dealing…

Reported is a study to compare science achievement of 318 ninth-grade students who came from different socioeconomic areas but all enrolled in an Earth Science Curriculum Project (ESCP) program. The students were divided into three socioeconomic groups: upper, middle, and lower. All were given a pretest in science achievement, a posttest, an…

This study was concerned with junior high school students' understanding of the scientific enterprise, the methods and aims of science, and of scientists. A comparison was made between the use of the Earth Science Curriculum Project (ESCP) and the traditional general science course approach. The ESCP sample was taught by teachers trained in the…

Presented in this monograph are 10 articles read at the Third Annual Conference of the Australian Science Education Research Association which was held in Melbourne in May, 1972. The articles are given under the following headings: A Model for Curriculum Evaluation; The Australian Science Education Project as a Stimulus for Research--A Progress…

The introductory core activities in this trial unit, prepared for students in grades seven through nine of Australian schools, use indicators derived from flower pigments to provide a more convenient measure of acidity than taste. Students are offered choices among seven options after completion of the core: "How Acidic is That?";…

This volume is one of the series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation. It consists of discussions, exercises, and experiments on the following topics: ion exchange, electrphoresis, dialysis, electrochemistry, corrosion, electrolytic cells, coulometry,…

Described are alternative approaches for developing visual perception skills found in using selected science experiences. Use of various science programs available, such as ESS, SCIS, OBIS and Matal, is suggested. Visual sequencing is prescribed and described. (EB)

Analyzes several factors in an impact study of Biological Sciences Curriculum Study (BSCS) and states that its major impact has been to make curriculum change respectable. (LS)

Indicates how the gas laws can be derived and taught to high school and college physical science classes by using the guided-discovery method. (LS)

Focuses on the response of the National Science Foundation (NSF) and the congressional authorization committees to the NSF sponsored precollege science programs. The article also summarizes and analyzes some of the results of the survey conducted by the Research Triangle Institute (RTI), North Carolina. (HM)
