This paper reports on the use of portfolios in a continuing professional development programme to advance teachers' skills in their pedagogy of argumentation. The programme adopted a cyclical process of expert input-teacher practice-sharing practice, in order for professional learning to include reflective analysis of growing accomplishment.…

We describe an evidence-based continuing professional development programme on knowledge integration (KI) for high-school physics teachers. Sixteen teachers participated in the year-long programme (about 40 face-to-face lessons and in-between computerised interactions). The teachers experienced the KI activities as learners and then engaged in an…

This evaluation used a change transition model to explore the processes of development of a three-phase professional programme devised by two teams of researchers to support teachers' expertise in six domains of science teaching. The full programme operated over two years. Interviews with developers at the end of each phase (21 interviews) and…

In this study our goal was to better understand the development of chemistry teachers who are involved in a continuous professional development (CPD) programme, focusing on using the inquiry approach in the chemistry classroom-laboratory, followed by protocols assembled in a portfolio that can be used to demonstrate evidence-based practice in…

A programme of professional development was designed consisting of 20 hours of workshops plus in-school activities. The implementation of new pedagogy was supported by teachers bringing examples of their work in the classroom to the workshops for discussion and reflection. The purpose of this study is to explore factors that influenced what…

The aim of this study is to understand the influences on chemistry professors' use of educational technology. For this, we use activity theory to focus on two university chemistry professors and the broader activity system in which they work. We analyse their beliefs and past experiences related to teaching, learning, and technology as well as…

This study explored the effects of a cognitive intervention program, Cognitive Acceleration in Science at Key Stage 1 (CASE@KS1), on both the thinking skills and motivation of a rural population in the United Kingdom. It used a quasi-experimental design and measures of both near and far transfer in order to replicate the evaluation of this program…

Australia wide, all school systems are in the process of providing teachers with computers and there is an expectation that new teachers will possess the expertise to use them in their teaching. In addition to using computers for basic word processing and data manipulation, early-career science teachers need to be able to use a range of…

This study investigates the strategies and assumptions that college students entering an introductory physical geology laboratory use to interpret topographic maps, and follows the progress of the students during the laboratory to analyze changes in those strategies and assumptions. To elicit students' strategies and assumptions, we created and…

This is an interpretive case study seeking to develop detailed and comparative descriptions of how two groups of fifth-grade students used two different Computer-based Programming Environments (CPEs) (namely Microworlds Logo and Stagecast Creator) during scientific modelling. The primary sources of data that were used in this 4-month study include…

Scale is one of the thematic threads that runs through nearly all of the sciences and is considered one of the major prevailing ideas of science. This study explored novice and experienced teachers' concepts of spatial scale with a focus on linear sizes from very small (nanoscale) to very large (cosmic scale). Novice teachers included…

The rapid growth of biotechnology knowledge during the past decades has made it necessary to rethink the contents of the school curriculum and has provoked a consideration of the ethical and social issues related to the use of biotechnological applications. With the financial assistance of the European Union, the European Initiative for…

Previous studies have indicated that A-level students in the UK and Singapore have difficulty learning the topic of ionisation energy. A two-tier multiple-choice instrument developed in Singapore in an earlier study, the Ionisation Energy Diagnostic Instrument, was administered to A-level students in the UK, advanced placement high school students…

Visual representations play an important role in science teaching. The way in which visual representations may help children to acquire scientific concepts is a crucial test in the debate between constructivist and socio-cultural oriented researchers. In this paper, the question is addressed as a problem of how to contextualize conceptions and…

Reading and writing stories with science-related themes make it possible for students to develop interest in and capacity for scientific thinking when specialist science and more popular genres converge. Additionally, feminist scholars have called for greater use of creative writing activities in school science to counter students' disengagement…
