The purpose of this study was to determine parent/caregiver effectiveness at finding out their child's ideas about sinking, floating, and displacement. The quality and richness of responses obtained by the parent/caregiver were compared with responses from interviews of the same fourth grade students conducted by project staff. Twenty four…

This paper explores what it means, and what it might mean, to "achieve" in literacy. The paper points out that, although there is considerable concern over the misrepresentation of literate achievement by standardized tests, there has been substantially less demonstration of what is being left out, that is, exactly what of significance is achieved…

This study investigated fourth graders' (N=18) self-generated analogies and the effects of their collaborative reasoning and arguing over these analogies on individual understanding of three scientific phenomena concerning air pressure. The data were subjected to both a qualitative and quantitative analysis. The first showed that the children, on…

The purpose of this investigation was to compare the knowledge regarding marine organisms and their feeding relationships of fourth grade residents of one coastal and one inland community in south Texas and to generate grounded theory concerning the participants' construction of such knowledge. Four male and four female students were randomly…

To make elementary science students grasp the scientific concepts being taught, teachers must not ignore their preconceived ideas. Instead, teachers must identify misconceptions then help the students test them. The article presents a step-by-step approach that can serve as a model for teaching any science concept. (SM)

This unit contains six lessons on rocks for fourth graders. It describes materials, supplementary materials (including films, units, and books) schedule, unit introduction, and background information for teachers. Lessons include: (1) "Rocks Are Everywhere"; (2) "Chart Making"; (3) "Things Are Breaking Up"; (4)…

This unit contains 15 lessons on Alaskan plants for fourth graders. It describes materials, supplementary materials, use of process skill terminology, unit objectives, vocabulary, background information about five kingdoms of living things, and a webbing activity. Included are: (1) "Roots in Action"; (2) "Chlorophyll"; (3)…

Evaluates the effects of the scaffold explanation-based approach to collaborative discussion on students' understanding of photosynthesis. Forty-eight fourth- and fifth-grade students were divided into groups of high, average control (AC), and average intervention (AI). Students worked collaboratively and individually on two reasoning tasks.…

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…

The purpose of this study was to investigate the effect of selected science experiences on fourth-grade students' concepts of Piagetian physical causality, namely, animism and dynamism. Vocabulary ability and Piagetian developmental stages were assessed by the "Concept Assessment Kit Conservation" and "Metropolitan Achievement…

Many current studies have discovered that students tend to use either an Aristotelian or the Medieval impetus model rather than the Newtonian view in order to explain their experience. This preconceived knowledge may be important for students in learning mechanics. The purpose of this study was to identify and confirm the existence of a…

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…

Some pre-instructional misconceptions held by children can persist through scientific instruction and resist changes. Identifying these misconceptions would be beneficial for science instruction. In this preliminary study, scores on a 60-item true-false test of knowledge and misconceptions about earthquakes were compared with previous interview…
