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,…

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…

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

Discusses the development and use of flowcharts to involve students in the major stages of experimental design and hypothesizing. The progress of stages attempts to simplify the complexity involved during problem-solving in science investigations. Several illustrative flowcharts are included. (JN)

Discusses the concept of quality, relates quality to four themes of the evolving science curriculum, and examines implications for science teacher education. The four curriculum development themes focus on problem-solving skills, the cultural heritage, a conceptual framework of the realm of science, and moral/ethical issues resulting from…

An appreciation of the relationship between novice and expert knowledge frameworks may help develop an understanding of the process of transition from one to the other. Recommends the use of concept mapping. (DDR)

Raises questions about the widely accepted rationale of teaching scientific methodology in order to help students become better problem solvers in nonscience settings. Argues that it is better to teach problem solving skills within familiar contexts not complicated by difficult subject matter. (DC)

Examines quantitative models in school physics, looking particularly at the degree to which they match the real world. Explores the positive aspects of a mismatch between models and real world conditions. (DDR)

Discusses the process of problem solving, stressing the iterative nature of the process and the importance of communication (explaining problems to others). Provides examples of physics/physical sciences problems useful in problem-solving competitions. Also provides examples of problems to be solved in school over several weeks. Lists of materials…

An astrophysics course based on the constructivist approach to science teaching is described. The study of galactic structure is given as an example. Direct experiences and observations, representative-symbolic language, organized knowledge, and formal strategies are emphasized. (KR)

Describes the characteristics of task-centered explorations. Provides definitions and examples of types of task-centered activities. Analyzes factors which produce an uneven distribution pattern in the type of explorations that pupils experience. Discusses the implication of these analyses for classroom teachers. (CW)

Promotes the use of computer modelling in physics instruction. Describes Dynamic Modelling System (DMS) and the procedures employed in applying it to problem solving in physics. Provides fundamental information on BASIC language and techniques for using DMS. (ML)

Describes the construction of a chemistry laboratory. Also discusses the place of science in school technology teaching, a study of students' understanding of simple quantitative relationships in chemistry, and the objectives of school physics. (JN)

Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)
