Proposes methods for the optimal popularization of science and technology to shape and influence public opinion about the utility of associated policies and goals. Emphasizes that such popularization should concentrate on enabling laypeople to acquire an adequate level of scientific and technological literacy, applicable to their everyday lives.…

An investigation in which science/technology/society (STS) strategies were utilized for one class and traditional concept-organized strategies were utilized in another is described. Results are contrasted for students enrolled in an STS section and others in a non-STS section. Advantages of the STS program include improving process skills,…

The joint preparation of teachers and principals for leadership in the improvement of elementary and middle school science instruction is discussed. An inservice program through which existing staff increased their science expertise is described. Schools are encouraged to build up their science programs through enhancement of the qualifications of…

Using the construct of personal self-efficacy as a foundation, methods for building science teaching confidence in preservice teachers are described. Methods include microteaching, cooperative learning, role models, experiential learning, computer use, and others. The interrelatedness of science anxiety, attitude toward science, and low science…

Experiences with an instructional strategy which enabled students to build for themselves the appropriate scientific concept for energy are described. This was done by pupil/teacher dialogue in small groups, in which students were expected to create for themselves a "generalization mechanism" based on their own frameworks. (KR)

An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

Grade 11 students enrolled in a science/technology/society (STS) course, students not enrolled and their respective teachers were profiled. The results indicate that STS education rather that STS "doctrination" is the norm, the goal of "STS-literate" students has not been achieved, and the long-term retention capability of the established and…

The supposition that observational skills can be influenced by students' belief in traditional African cosmology, beliefs, and superstitions was investigated. Students with a high level of belief in African traditional cosmology made fewer correct observations on the Traditional Cosmology Test (TCT) and the Test of Observational Skills (TOS) as…

The interaction effect between two process skills (application and interpretation) and two task contexts (scientific and everyday) was investigated. Korean students (n=255), ages 13 and 15, were the subjects of this study. Results reveal that there was an apparent interaction between process skills and contexts. Sex-skill interaction and…

Children of 2 different age groups (11-12, n=246; and 13-14, n=196) were asked to draw and write about dissolving in 2 different ways. Greater percentage of children at both ages gave accurate particle interpretation that accurate view of observable process. Consistency between two ways of looking at dissolving was not found to improve with age.…

Two questionnaires were given to 38 students (16-18 year olds), in which they were asked to classify a list of different conceptual entities by several ontological features. The results suggest the form of a fundamental "ontological space" and locate some scientific concepts in this space. (Author)

In search of a better understanding of the learning difficulties in basic electricity, learning results, interest, achievement motivation, IQ, and cognitive development were investigated in students from both urban and rural schools. An analysis reveals that, for urban classes, learning is related primarily to interest and motivation and, for…

The consistency, if any, with which force concepts are used by individual students in different, but closely related, contexts was investigated. A total of 534 university and high school students were tested to elicit their beliefs about the forces acting on various objects. Students' beliefs about the forces acting on objects at rest and in…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does not derive from school…

Conducted a study to determine the value of using metaphors to understand learning environments, determine if prospective elementary teachers gain an understanding of traditional and constructivist learning environment research, and explore the implications for teacher education. Reports that the use of metaphors helped teachers understand and…
