Reviews the science enrollment and achievement patterns of males and females studying in a new high school unit curriculum structure in Western Australia. The data indicate that lowering the age for subject choice is associated with a reduction in the amount of science studied, especially by females, and with the early manifestation of…

Training consisting of concept acquisition tasks was given to elementary and secondary students (n=175). Results revealed that none of the five- and six-year-olds, approximately half of the seven-year-olds, and virtually all of the eight-year-olds responded successfully to the training. (PR)

Examined 57 randomly selected elementary bilingual/bicultural science classrooms in terms of culturally syntonic variables (e.g., culture-of-origin beliefs and/or practices that impact the teaching/learning process). Some findings indicate that Hispanic/Latino children are receiving science instructions with culturally asyntonic materials and in…

The experimental/analogy group scored significantly higher than the control group on a posttest question that required the definition of diffusion (n=77 community college students). Hypothetico-deductive reasoning skill was significantly related to correct application of the diffusion concept to a change from the misapplication of the polarity and…

Evaluated the effects of cooperative learning on students' (n=36) verbal interaction patterns and achievement in a conceptual change instructional model in secondary science. It was found that students using cooperative-learning strategies showed greater achievement gains and made greater use of specific verbal patterns believed to be related to…

Explored three modes of performance-based assessment: portfolios, portfolio-based simulations, and simulation exercises. Fifteen high school biology teachers completed 11 assessment activities. The primary finding is that performance-based assessments can be designed and administered, teachers can complete them, the assessment can be rated, and…

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

Students' understanding of the concept of relative speed is described. A variety of ways of understanding relative speed and of viewing a problem that dealt with this concept were uncovered. The results are used to suggest ways for teachers to proceed in assisting students to enhance their understanding of relative speed. (PR)

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

This article reports on a study that was designed to describe prospective elementary teachers' prior verbal and diagrammatic knowledge about various aspects of light, seeing, shadows, and mirror images. Data were collected through individual interviews using simple apparatus. Included are some inferences about how students' ideas may have emerged…

In this defense of Piagetian constructivism, sociocultural constructivism is critiqued as nihilistic, culturally relative, and dangerous when placed in the context of real science classrooms. (PR)

Carried out an investigation to identify conceptions of some components of worldview held by science student teachers (n=48) in a South African context. Explores relationships among worldviews, student characteristics, and scientific concepts. Reports that students' conceptions of time and distance were nonmechanistic and psychologically bound and…

Explores preservice teachers' (n=151) metaphors of teaching and learning and examines some components of student teachers' own intuitions. Concludes that metaphors communicate a richness of meaning that conveys elements of mood, control, roles, attitudes, and beliefs as they apply to teaching and learning and are grounded on more deeply rooted…

Describes a heuristic inquiry process attempting to better understand and appreciate a major aspect of religion influenced culture in the southern United States which has an impact on science education. Examines the intellectual and emotional viewpoints of scientists, science educators, and science teachers regarding the relationship between their…
