The study explores urban second graders' thinking and talking about the concepts of evaporation, boiling, and condensation that emerged in the context of intertextuality within an integrated science-literacy unit on the topic of States of Matter, which emphasized the water cycle. In that unit, children and teacher engaged in a variety of…

This study investigates the effect of a conceptual change approach over traditional instruction on students' understanding of chemical equilibrium concepts (e.g. dynamic nature of equilibrium, definition of equilibrium constant, heterogeneous equilibrium, qualitative interpreting of equilibrium constant, changing the reaction conditions). This…

In this paper we present a simple set-up that illustrates the mechanism of sap ascent in plants and demonstrates that it can easily draw water up to heights of a few meters. The set-up consists of a tube with the lower end submerged in water and the upper one connected to a filter supported by a standard filter-holder. The evaporation of water…

This paper attempts to draw attention to non-conventional but popular modes of transmitting scientific knowledge in Jesuit institutions in the 17th century. The particular case study focuses on a fictive dialogue between Galileo, Mersenne and Paulus Guldin on the power needed for moving the huge globe of the earth by mechanical means. The dialogue…

Those who are most marginalized, both culturally and economically, in society are concentrated in the nation's largest urban centers and have the least opportunities to be successful in school science or to pursue higher education and career trajectories in science, mathematics, or engineering. This article shares the results of a study in which…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

This guide is one of a set of 10 science guides, each covering a separate grade in Manitoba, together covering kindergarten through grade 9. The guides have been designed to provide a framework for building scientific concepts and developing the learning of process skills. They replace an earlier set of guides dated 1979. Each guide is essentially…

This science curriculum is a basic science program suitable for middle or junior high school science classes. The book is designed for use as a "worktext" or text book and emphasizes a wide range of science skills and concepts to provide students with post-school knowledge and the ability to successfully complete a proficiency or a…

This concept paper outlines the rationale for a project on the development of science curriculum for K-8 high ability learners. The rationale was developed through a synthesis of major recommendations from national science reform reports and from a review of the literature on effective science curriculum for high ability learners. The paper begins…

"Talking Science" does not mean simply talking about science; it means doing science through the medium of language. This is a book about communication, scientific, and technical education. Chapters 1 and 2 introduce the specific themes and methods of the book. Each analyzes a brief classroom episode, looking from two different points of view at…

This book is designed as a resource for teachers and parents concerned with early childhood education. It is hoped that the ideas and activities presented herein will serve in the creation of a space science and mathematics curriculum that is both child-centered and exciting. The basic philosophy for this curriculum is that of Piaget. This…

The distinction between the participant and spectator functions of language are used to describe the teaching skills of a fourth grade teacher during a unit of instruction. This study documented the science instruction of a teacher who 20 years ago majored in teaching reading. In recent years she has taken steps to develop skill and knowledge in…

This paper begins by exploring some general issues associated with the idea of progression in education in general and in science education in particular. These are then related to the particular domain of interest of the Procedural and Conceptual Knowledge in Science (PACKS) Project, which is concerned with the responses of children, aged 9 to…

To determine the factors that influence interpretation of a research study description, 8 descriptions of research studies were interpreted by 320 undergraduate students in psychology, mathematics, and economics statistics and research methods classes at the University of Victoria (British Columbia, Canada), Millersville University (Pennsylvania),…

The first (exploratory) phase of the Learning in Science Project focused on science teaching/learning in the Form 1 to 4 level (ages 10 to 14) and sought to identify problems and difficulties in several areas. Provided in this paper are comments obtained during structured/unstructured interviews (from students, ex-students, teachers, headmasters,…
