Even though several studies have reported positive attitudinal outcomes from context-based chemistry programs, methodological obstacles have prevented researchers from comparing satisfactorily the chemistry-learning outcomes between students who experience a context-based program with those who experience a content-driven program. In this…

The purpose of this study is to understand in what ways a technology-enhanced learning (TEL) environment supports learning about the causes of the seasons. The environment was designed to engage students in five cognitive phases: Contextualisation, Sense making, Exploration, Modeling, and Application. Seventy-five high school students participated…

Traces the curriculum changes in science in junior technical schools in the 1960s. Focuses on one episode of curriculum change to illustrate how curriculum and cultural change are mediated by educational actors who employ the rhetorics and reforms which emanate from their society to pursue agendas within their workplace and locality. Contains 52…

Although laboratory activities are widely acknowledged as being fundamental to the teaching of science, many secondary science school teachers have limited knowledge of how to design and run effective teaching laboratories. Utilising a situated cognition theoretical framework, we discuss our collaborative efforts to develop a laboratory based…

This paper investigated the change of the Junior Secondary School Chemistry Curriculum (JSSCC) in the P. R. China over the period from 1978 to 2001. Document analysis was employed as the research method and data were collected from various versions of teaching syllabi, textbooks, and teachers' reference books published during this period. The…

This interpretive study of a Year Six classroom in North Queensland, Australia focuses on how two contrasting groups of children designed ill-defined engineering structures. The collaboration processes within the research team are explored. Classroom-related findings are also reported. (AIM)

We investigated the pedagogical content knowledge (PCK) of nine experienced chemistry teachers. The teachers took part in a teacher training course on students' difficulties and the use of models in teaching acid-base chemistry, electrochemistry, and redox reactions. Two years after the course, the teachers were interviewed about their PCK of (1)…

Students are generally known to memorise and regurgitate chemical equations without sufficient understanding of the changes that occur at the particulate level. In addition, they often fail to recognise the significance of the symbols and formulas that are used to represent chemical reactions. This article describes an evaluation of the ability of…

This paper explores the different types and characteristics of preschool children's explanations of plant growth and rain formation. The children's explanations were categorized as naturalistic, non-naturalistic, or synthetic, i.e., explanations containing both naturalistic and non-naturalistic parts. In regards to plant growth the children…

An element of current reform in science education worldwide is the shift from the dominant traditional algorithmic lower-order cognitive skills (LOCS) teaching, to the higher-order cognitive skills (HOCS)-promoting learning; that is, the development of students' capabilities including those of question asking (QA), critical/system thinking (CST),…

Suggests that the results of the Third International Mathematics and Science Study (TIMSS) rank Western Australia as first in the world in science. Examines a statewide curriculum reform initiative that focuses on primary level science teacher leaders. Contains 27 references. (DDR)

Sheds light on views held by those who enjoy a certain degree of institutional legitimacy for talking about science either as practitioners in the field of science or as guidance counselors working with students interested in having science-related careers. Contains 60 references. (DDR)

The new 1?9 curriculum framework in Taiwan provides a remarkable change from previous frameworks in terms of the coverage of content and the powers of teachers. This study employs a modified repertory grid technique to investigate biology teachers' preferences with regard to six curriculum components. One hundred and eighty-five in-service and…

Presents a fictional account of a science teacher and her use of constructivism as a referent for her various roles. Describes how she came to teach in this manner, her involvement in staff development activities, and an evolution in her thinking from an objectivist to a constructivist system of semantics. Presents implications for the reform of…

Examines the multiple uses and definitions of invention in science to develop a theory of invention and inventive acts around themes related to invention as a social act, invention as a recursive and socially linked process, and invention as an embodied agency. Contains 56 references. (DDR)
