Nature of science (NOS) is a key component of scientific literacy, so science teacher education on NOS is critical to ensure students' scientific literacy. According to mainstream NOS literature, explicit and reflective interventions are recommended to effectively teach NOS. This paper presents an experience for the initial education of secondary…

Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…

This literature review provides an overview of recent studies on the introduction of nanosciences and nanotechnologies in secondary education. Four salient research topics have emerged: questions and reflections preceding curriculum development on nanosciences and nanotechnologies lessons; research on students' conceptualisations of nano-related…

A series of aspects regarding the aria of teaching sciences (chemistry, biology, physics, geography) in pre-universitary learning is presented. This paper underlines the importance of prerepresentations of students in teaching-learning process in pre-universitary learning, assuring in this way a desirable direction of the reform in…

Reports on a study designed to ascertain the proportion of children at different Piagetian stages of development in the general population, in selective schools, and in super-selective schools. Advocates the use of developmental data in curriculum development work. (GS)

Questions the approach used to the topic of energy in Nuffield Secondary Science. Indicates that 14-year-old children will not be able to generalize from the experiments to see a pattern energing, and the concept of energy involves understanding of other concepts that the children have not yet attained. (GS)

A THEORETICAL FRAMEWORK AND GUIDELINES FOR SCIENCE CURRICULUM DEVELOPMENT ARE PRESENTED IN THIS VOLUME. THE BOOKLET CONSISTS OF THREE SECTIONS PLUS AN APPENDIX. IN THE FIRST SECTION A SCIENCE EDUCATOR PROPOSES A PLAN FOR SCIENCE TEACHING COMPATIBLE WITH THE NATURE OF SCIENCE, CULTURAL CHANGES, AND THE EXPANDING BODY OF KNOWLEDGE. THE CHOICE OF…

This workshop is based upon work and findings of the Learning in Science Project, a research project which investigated problems and difficulties in the teaching and learning of science. The workshop program, including activities which have been shown to impact on teacher thinking, is designed to focus attention on learning problems in classrooms,…

Reported are compulsory education pupils' representations of electric current in a constructivist approach to introducing direct current (DC) circuits. Suggests that the pupils views can be modelled after an energy framework. Makes suggestions about the content, the apparatus and the experiments used in teaching DC circuits. (CW)

Examines several areas to be considered in developing physics syllabi. They include (1) the objectives of physics teaching and learning; (2) physics as an experience, based on realistic expectations of what 14- to 16-year-olds are capable of; and (3) the kinds of experiences in which students can succeed (including computer experiences). (JN)

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…

The Learning in Science Project has adopted the view that science teaching might be improved if teachers can be given some appreciation of students' views of the world and the beliefs, expectations, and language that learners bring to new learning situations. This investigation compares and contrasts views that children and scientists have on…

Discusses the meaning of Schwab's "substantive structures" of a discipline in terms of science philosophy. Presents three techniques for representing substantive structures and discusses some of their uses in science education research. (SK)

Building explanations is fundamentally what science is about. Students require support both for constructing their own explanations about the surrounding world, and for reflecting on those explanations in ways that help them to assess the quality of their explanations and the strategies they use to build them. This paper describes the development…
