Presents a refined method for designing a valid and reliable Likert-type scale to test attitudes toward the generation of electricity from nuclear energy. Discusses various tests of validity that were used on the nuclear energy scale. Reports results of administration and concludes that the test is both reliable and valid. (CW)

Compares the effectiveness of two instructional models in bringing about a valid understanding of science concepts in prospective elementary teachers. Describes the two instructional models; an expository model and a learning cycle model. Concludes that college students understandings of science concepts may be improved using a combination of the…

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

Analyzed and compared the teaching behavior of teachers who had been trained to use Science Education Project (SEP) materials with the teaching behavior of teachers using traditional approaches. Reviewed some relevant research on observations of science teaching and presented the results of the comparative study. (CW)

Examines various types of problems that researchers have used to demonstrate problem solving. Focuses on genetics problems. Discusses classes of learning outcomes, conceptual knowledge gains, content-independent heuristics, content-specific procedures, understanding the nature of science and a typology of genetics problems. (CW)

Studies the quality of graduating science education majors at Brigham Young University (BYU) and attempts to identify possible trends in the ability of students who entered secondary school science teaching. Concludes that there was no manifested trend toward lower quality college students entering the science teaching profession at BYU. (CW)

Discusses the history of American science and science education, with particular emphasis on the development of scientific inquiry and experimentation. Focuses primarily on the activities of individuals in the 1800's, and the introduction of science into secondary schools and higher education institutions in the early 1900's. (TW)

Describes a specially designed preparatory course in science and mathematics for relatively "unprepared" adult students in Israel. Compares the achievements of these students with the achievements of those identified as "prepared" according to their formal education and qualifications. (TW)

Reports on a study to determine the interaction effects of selected personality characteristics, science achievement, and two classroom climates, one which encouraged discovery learning and one that did not. Demonstrated that student achievement is influenced by dynamic interactions within classrooms. (TW)

Describes strategy analysis procedures which enable preservice teachers to implement science lesson segments in a manner that was consistent with strategies incorporated into science teaching models. Conformity to the model was uniformly high for phases related to preparing the learner, investigation planning, and data processing. (JN)

Determined if a written, persuasive communication would positively affect the attitudes of preservice teachers (N=98) and if the communication would differently affect subjects rated on three levels of self-esteem. Results indicate written persuasive communication could change the attitudes of the preservice elementary teachers in this study. (JN)

Examined elementary and secondary education students' attitudes and understanding of science processes prior to taking methods courses, immediately after completing the courses, and upon completing their practice teaching experiences. Implications based on differences in attitudes between the two levels (including negative attitudes for secondary…

Analyzes three approaches (physical, mental, combined practice) to improving freshman chemistry psychomotor laboratory skills. Although no significant differences were found between treatments, there were significant differences when each was compared to the control sections. Mental practice appears to offer an efficient methods for reinforcement…

Critical shortages in science and mathematics teacher education enrollment at Black colleges and universities are discussed. Questionnaire results from Black colleges (N=47) are used to compare bachelor's, master's, and doctoral degrees awarded to Blacks in various fields. (DH)

Concept maps and structured/clinical interviews were completed by 25 fourth graders and 25 college freshmen to determine knowledge of the human circulatory system. Students (N=945) at various levels were then measured for misconception frequencies. Student preconceptions appear to be tenacious, but confrontation strategies may assist fundamental…
