There has been widespread interest in the study of oxoacids of phosphorus owing to their characteristic structures and uses in various areas of daily life. In this article, a new strategy is recommended to determine their structures. This strategy will help to develop problem-solving skills and creativity among students. The strategy is based on…

Ideas are offered to show how the science of density and displacement can be explored by students from year 5 through to year 7 (ages 9-12) through hands-on investigations to explore possibilities and solve problems. These demonstrate how the insights we gain by viewing a challenge through the multidisciplinary lenses of science, history,…

To improve the quality of education, it is important for teachers to have an understanding of action research. Action research is 'learning by doing', which involves identifying a problem, looking for a plan to resolve it, observing how successful it is and, if not satisfied, trying again. Action research helps educators to be more effective in…

This article describes how a class of year 9 (age 13-14) students engaged in a research-informed and negotiated action science project to address socio-scientific issues. The project was informed by the 'STEPWISE' curriculum framework. Evidence suggests that students benefited from collaborative problem-solving, developing confidence, motivation…

This article examines how students taking a post-compulsory physics course for 16- to 19-year-olds (A-level physics) benefited from a change in pedagogy which meant that they spent more time problem solving in collaborative groups. Video analysis of these collaborative problem-solving sessions revealed that the students improved a number of key…

This article focuses on the importance of activity-based teaching in understanding the mole concept and the vital role of basic mathematical operations. It describes needs-based training for teachers in a professional development programme in India. Analysis of test results before and after the training indicates that teachers improved their…

Our view of learning takes into account how learners, when learning, are engaged in both doing science and mathematics and becoming mathematicians and scientists. Drawing on our work on a number of European projects that developed inquiry approaches across mathematics and science, we propose a new research and development agenda seeking new ways…

In 2000, the Programme for International Student Assessment (PISA) study was conducted by the Organisation for Economic Co-operation and Development (OECD). It is a worldwide study of 15-year-old students' performance in mathematics, science and reading skills. The study showed relatively poor results for German students' scientific literacy…

Explored is the role of thought experiments in the development of physical theories. Drawing examples from quantum theory it asks how a method that generates no new empirical data can nonetheless exert an influence upon a subject defined by its empiricism. (Author/KR)

Reports on research attempting to identify the stages, skills, and strategies associated with children's (N=60) problem solving. Reports that conclusions including the creation of a five-stage model of problem solving are relevant not only to children in the 5-14 age group but to pupils undertaking a specific science course from year 10 onward.…

Identifies the misunderstandings and problem-solving strategies of secondary students when solving stoichiometry problems. (Author/CCM)

Summarizes the role of analogies in moving science forward and discusses the usefulness of generating analogies in the science learning process. (Author/YDS)

Schematically depicts the variety of uses the mole concept has for 0-level chemistry. (CP)
