"Experience" is one of the most used terms in (science) education, and it is recognized as being related to learning (education). Yet "what" experience is and "how" it is related to learning and change remains untheorized. In this paper, we mainly draw on the work of J. Dewey and L. S. Vygotsky but also on M. Bakhtin…

The aim of this study is to examine the effectiveness of collaborative learning with hints and peer tutoring with hints, and individual learning with hints in chemistry laboratory education in a secondary school. A total of 96 eleventh graders participated in this study. The study has a randomized pre-test and post-test design with a delayed…

This article reports on the construction process of inclusion/exclusion for high school chemistry students in two schools in Belo Horizonte, the capital of Minas Gerais State, Brazil. We examined the interactional accomplishment of inclusion/exclusion of four students, two from a private school and two from a public school. The aim of this article…

This study investigates the influence of hands-on activities on students' interest. We researched whether students with experience in specific hands-on activities show higher interest in these activities than students without experience. Furthermore, the relationship between the quality of the hands-on experience and interest in the respective…

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students' epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes…

This paper argues for effective sequencing of mathematics content to aid transition from junior (Year 7 to Year 10) to senior mathematics (Year 11 to Year 12) curriculum in Queensland, Australia and provides a tool for sequencing the mathematics content. Planning templates and samples are available to schools; however, it is imperative for…

In this paper, we argue that during collaborative classroom interactions, 'the mangle' is entangled in different forms of agency that (dis)enable mathematical agency. We first unpack student's agency in the context of collaborative classroom interactions, and then use excerpts of interactions to illustrate how 'the mangle' is entangled in…

In Brunei, more girls are enrolled at the institutions of higher education than boys. The aim of this study was to evaluate if a constructivist teaching approach, enriched with interactive whiteboard technology could empower males to minimize gender differences in achievement in Chemistry. Two groups of students were taught for six weeks: one…

The present study conducted to investigate the contribution of conceptual change texts, accompanied by concept mapping instruction to eleventh-grade students' understanding of cellular respiration concepts, and their retention of this understanding. Cellular respiration concepts test was developed as a result of examination of related literature…

In an action research study, 66 students from Year 11 in an Australian school were shown the colour of methyl violet indicator in some hydrochloric acid solutions, and then in an acetic acid solution. The intent was to create a cognitive conflict, resolution of which would lead to an understanding of the concept "weak acid". Student…

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum…

Geometry plays an important role in the school mathematics curriculum all around the world. Teaching of geometry varies a lot (Hoyls, Foxman, & Kuchemann, 2001). Many countries revise the objectives, the content, and the approaches to the geometry in school. Studies of the processes show that there are not common trends of these changes…

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three…

A Korean science teachers' discursive practises were examined with a view to identifying pedagogical roles performed through his talk. Data came from the video recordings of classroom sessions where students presented their science projects and exchanged questions and answers during the presentations. Transcripts were developed and analysed in a…

In this paper, the authors argue that chemical knowledge in the classroom will be enriched by the application of characterizations of models drawn from a range of disciplinary backgrounds. This discussion highlights two important issues relating to chemical knowledge in the classroom: (1) the status of chemical knowledge in the classroom,…
