As the global economic crisis continues, sustaining the United States' position as a leader in research and development is a top concern of policy makers. Looking to increase the number of students pursuing degrees in STEM (science, technology, engineering, and mathematics), calls for improved mathematics and science education abound. We completed…

Decision making about socioscientific issues is an important aspect of modern science education worldwide. Among the many topics that represent socioscientific issues, issues relating to the sustainable development of our environment are one crucial topic. However, difficulties exist with respect to the assessment of teaching outcomes related to…

We describe a longitudinal study of a secondary education biology teacher at two moments in her career (1993-2002), determining the changes in her conceptions of the nature of science and its teaching and learning, and the factors that favored or hindered such changes. The changes were analyzed using cognitive maps, constructed on the basis of the…

There is evidence that alienation from science is linked to the dominant discourse practices of science classrooms (cf. Lemke, J. L. (1990). Talking Science: Language, Learning, and Values. Norwood, NJ: Ablex). Yet, in secondary science education it is particularly hard to find evidence of curriculum reform that includes explicit changes in…

Taking the Junior Secondary School Chemistry Curriculum (JSSCC) in the People's Republic of China as a case, this paper approaches the issue of the tension between elite and future citizenry orientations in science curriculum. The changes in the JSSCC over the period from 1978 to 2001 are explained from three viewpoints: sociopolitical,…

This work is grounded in a constructivistic conception of the learning of science, more particularly on the model known as teaching-learning as oriented research. In accordance with this theoretical basis we have developed an empirical research project to investigate the teaching of electrostatics in high schools. The designs developed have…

Investigates meanings of an innovative, reform-based curriculum (Active Physics) in various contexts. Explores how meanings of the curriculum transformed as it traveled across space and time. Discusses how aspects of the context enabled innovative science and those that constrained the potential of the curriculum. Demonstrates potential for…

Investigates preservice science teachers' beliefs about science teaching and learning through reflections on teaching lower track science students. Studies preservice teachers enrolled in a field-based secondary science methods course working with rural Black children. Discusses implications for teacher education and research. (Author/KHR)

Examines views and practices of first-year science teachers, graduates of a teacher education program in California, focusing on gender equity and multicultural education. Explores teachers' attempts at the nature of science and implementing equitable instruction in classrooms. Discusses commonalties across teachers' successes and struggles in…

Investigates the relationship between a science-technology-society (STS) approach, scientific literacy (SL), and achievement in biology. Uses two instruments for data collection, an achievement test on reproduction and family planning and an SL scale. Concludes that the STS approach might be affecting other variables in the science classroom that…

Describes the model-revising problem-solving strategies of two groups of students (one successful, one unsuccessful) as they worked in a genetics course to revise Mendel's simple dominance model to explain the inheritance of a trait expressed in any of four variations. Finds differences in the groups' abilities to recognize anomalous data, use…

Documents an instructional methodology to teach a fundamental reasoning skill during scientific inquiry: the evaluation of empirical evidence against multiple hypotheses. Uses an instructional framework with iterative cycles that lends itself to authentic scientific inquiry by providing a nontraditional approach to three aspects of learning: (1)…

Describes a science teacher's views of Science-Technology-Society (STS) instruction after implementing a two-semester STS-oriented science course in a Taiwanese high school. Concludes that the heavy content load of Taiwan's national curriculum, regular cross-class standard tests, lack of peer or administrative support, resource limitations in the…

Examines the influence of personal histories on the formation of early role identity as inquiry-oriented science teachers. Involves n=12 secondary science student teachers to illustrate the development of inquiry orientation. Discusses the role of learners' personal histories on their teaching identity development and implications for preparing…

Describes a project on labwork at upper secondary and undergraduate levels that was launched in 1996 and funded by the European Commission. Presents new research questions focusing on three objectives: (1) conceptual; (2) epistemological; and (3) procedural. (Contains 28 references.) (Author/YDS)
