Despite calls that the school science curriculum should develop among students an ability to understand and respond critically to science-related media reports, very little research has been directed toward an important matter relevant to that aim, namely, how children and young people, untutored, react to science in the news. This study sought,…

A large scale study involving 1786 year 7-10 Korean students from three school districts in Seoul was undertaken to evaluate their understanding of basic optics concepts using a two-tier multiple-choice diagnostic instrument consisting of four pairs of items, each of which evaluated the same concept in two different contexts. The instrument, which…

The study aims to demonstrate evidence of (a) students' conceptual change on solution rates; (b) students' sub-microscopic explanations of dissolution; and (c) retention of the concepts of solution rates. The sample consists of 44 Grade 9 students (18 boys and 26 girls) drawn purposively from two different classes (22 each) in the city of Trabzon,…

The focus of this research was an evaluation of the impact of teacher professional development (PD) on student achievement during implementation of a reform curriculum. The PD consisted of five four-hour workshop sessions distributed over the time teachers were implementing the reform curriculum in their classrooms. The research was conducted in a…

Pedagogical content knowledge is found to be a crucial part of the knowledge base for teaching. Studies in the field of primary technology education showed that this domain of teacher knowledge is related to pupils' increased learning, motivation, and interest. The common methods to investigate teachers' pedagogical content knowledge are often…

The purpose of this study was to compare the effects of a conceptual change approach over traditional instruction on tenth-grade students' conceptual achievement in understanding chemical equilibrium. The study was conducted in two classes of the same teacher with participation of a total of 44 tenth-grade students. In this study, a…

The aim of physics education is to generate understanding of physics and there is considerable anecdotal evidence that passing examinations in physics is not the same as understanding the subject. This paper describes how the areas of difficulties in understanding of physics were determined for pupils in Taiwan aged 13-15. Test material which…

Working memory capacity has been shown to be an important factor in controlling understanding in the sciences. Attitudes related to studies in the sciences are also known to be important in relation to success in learning. It might be argued that if working memory capacity is a rate controlling feature of learning and success in understanding…

The difficulties of learning chemistry are related to the nature of chemistry itself and the methods by which chemistry is customarily taught. Frequently, the way of presenting chemistry does not take into account the psychology of the learner. With senior school pupils (over 1600 were involved) in the Emirates, a series of studies was conducted,…

Any instructional theory that ignores the limits of working memory when dealing with novel information or ignores the disappearance of these limits when dealing with familiar information in unlikely to be effective. (Kirschner et al. 2006, 77) (Contains 1 table and 3 figures.)

Research in science education has referred to limitations in information processing resulting from both mental capacity and working memory capacity. Mental capacity is often conceptualised within the framework of the theory of constructive operators. However, the cognitive resources underlying working memory are not well specified within the…

Working memory capacity is now well established as a rate determining factor in much learning and assessment, especially in the sciences. Most of the research has focussed on performance in tests and examinations in subject areas. This paper outlines some exploratory work in which other outcomes are related to working memory capacity. Confidence…

A range of characteristics of learners is described and their relationship to working memory discussed in the context of teaching and learning in the sciences. The characteristics are extent of field dependency, visual spatial abilities, divergency and convergency. These learner characteristics were measured for a large sample of school pupils…

This study explored the effects of community-based service-learning (CBSL), supplemented with discussions and activities about diversity, on the self-efficacy beliefs of preservice elementary teachers regarding equitable science teaching and learning for diverse student groups. The study was conducted with 81 preservice teachers enrolled in four…

Finding appropriate instructional settings in science for students with disabilities is challenging, and the range of services or placements used is currently unknown. This study identifies administrative structures, instructional settings, and special/general education teacher roles in teaching science to students with disabilities. A phone…
