We explored adaptations to an elementary science methods course to determine how varied contexts could improve elementary preservice teachers' conceptions of NOS as well as their ideas for teaching NOS to elementary students. The contexts were (a) NOS Theme in which the course focused on the teaching of science through the consistent teaching…

In spite of the commendations for the use of portfolio assessment, there is still little evidence indicating that such assessment actually supports and encourages student learning. Hence, this research study aimed to empirically identify the effects of implementation of portfolio assessment on student learning and attitudes. True-experimental…

The aim of this study is to draw attention to the informal education aspect of the movies shown and to determine the awareness levels about physics in movies of a small group composed of university students. That is an evaluation had been made among the films dealing explicitly with the basic content of physics, except for science fiction movies,…

This study investigated the effect of conceptual change text-oriented instruction over traditional instruction on students' understanding of solution concepts (e.g., dissolving, solubility, factors affecting solubility, concentrations of solutions, types of solutions, physical properties of solutions) and their attitudes towards chemistry. The…

This paper tracks the individual development of metacognition in two five year old children over an academic year as they engage in a cognitive acceleration through science education programme CASE@KS1. Using qualitative analysis and case study methods it demonstrates how collaborative group work with small children impacts on the development of…

This paper addresses the problematic nature of pupils' attempts to use their science conceptions in contexts other than the ones in which the original learning of the concept takes place. It reports research with 60 Year-5 primary school children studying current electricity, during which the researcher employed metacognitive activities alongside…

A series of studies were conducted to investigate students' metacognitive development in a second year chemical engineering course. The first of these was an exploratory study involving observation together with some limited interviewing. This was followed by a major study with two phases, the first of which involved a series of individual…

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),…

A debate is ongoing in Hong Kong regarding whether local and international schools vary in the extent to which they provide classroom learning environments that support the development of students' higher order thinking and metacognition. This study investigated commonalities and variations in the metacognitive orientation of local and…

The purpose of this article is to review recent research on self-regulated learning and discuss the implications of this research for science education. We draw on examples of self-regulated learning from the science education literature to summarise and illustrate effective instructional methods and the development of metacognitive understanding…

Given that the subject department is recognised by subject specialist teachers as the central and immediate unit of organization in secondary schools it is surprising that so little attention has been paid by researchers to the leadership dynamics within science departments. The leadership dynamics within the science departments of two…

This study examined the features of peer argumentation in middle school students' scientific inquiry. Participants were two boys and six girls in grade 8 of a middle school in Seoul, Korea. Students engaged in open inquiry activities in small groups. Each group prepared the report for peer review and then, during the peer discussion, presented…

This paper addresses the question of how to develop prospective teachers' pedagogical content knowledge (PCK) in science teacher education. The main focus is on the knowledge transformation process and on the cognitive strategies used to shift prospective teachers' explanations within the domain of modelling thermal physical phenomena. This study…

Difficulties in students' understanding of the spherical model of the Earth have been shown in previous studies. One of the reasons for these difficulties lies in beliefs and preliminary knowledge that hinder the interpretation of the scientific knowledge, the other reason may lie in the low level of verbal and visuo-spatial abilities. The study…

This paper reports and discusses the principal findings of an Australian study exploring the decisions of high achieving Year 10 students about taking physics and chemistry courses (Lyons, 2003). The study used a "multiple worlds" framework to explore the diverse background characteristics that previous quantitative research had shown were…
