Computationally intensive science (CIS)-related disciplines and careers are predicted to be among the cutting-edge fields and high-demand jobs. Such disciplines and careers demand expertise in both traditional scientific knowledge and computer science (CS)-related understanding and skills. Preparing educational systems for developing interest and…

In this study, the purpose is to develop and illustrate a method that facilitates investigations of students' learning processes in classroom discussions about socioscientific issues. The method, called transactional argumentation analysis, combines a transactional perspective on meaning making based on John Dewey's pragmatic philosophy and an…

It has been argued that learning science may be complicated, and even compromised, when students hold worldviews that may seem at odds with what is presented in science lessons.

Findings from a quasi-experimental study of children's ideas about the solar system and how these ideas changed in response to a 10-week intervention period of formal astronomy teaching at a single primary school in England are presented in detail. Initial interviews with all of the 9- to 11-year-olds involved revealed a relatively poorly…

This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

Illustrates the construction of conceptual models on pressure and flotation using high school students' previous ideas on these concepts. Identifies three models and uses them to analyze students' ideas about physical phenomena and to recognize the inferential structure they use. Contains 28 references. (DDR)

Given the important role of science teacher educators in developing science teachers' understandings of nature of science (NOS), this study explores 15 Turkish "prospective" science teacher educators' beliefs about NOS in the context of teacher education reform in Turkey. A reflection-oriented qualitative approach was adopted in the…
