Discussion of how the nature and use of visual and verbal meaning-making systems vary across formats. Focuses on a comparative study of CD-ROMs and printed books dealing with scientific concepts in upper primary grades. Topics include linguistic and visual semiosis; the use of images; and meanings in images. (Author/LRW)

Examines the relationship between children's use of metaphors and their mental models concerning the ozone layer and ozone layer depletion. Results indicate that the way children represent the role and depletion of ozone is strongly correlated with the types of metaphors they use while constructing and/or articulating their models. Also discusses…

Presents strategies for getting organized and creating a classroom environment that promotes science learning for primary students. Teachers must first decide what topics they are going to cover and what materials they need. Next, they should determine how to organize the materials. Finally, they should identify and set up areas in the classroom…

Describes a science experiment that gives students experiences with the float-sink phenomena and allows them to practice what Piaget called formal operational thinking. The goal of the experiment is to determine some of the variables responsible for cans of soda sinking or floating. (TJQ)

Argues that science education is a fundamental tool for global education and that it must be introduced in early years as a first step to a scientific culture for all. Describes testing validity of a didactic strategy for developing the learning of concepts, which was based upon an experimental work approach using everyday life contexts. (Author)

Explores the use of classroom cases as instructional material, vehicles for inservice education, and as raw data for research on teacher cognition. (Author/CCM)

This research was conducted to examine the conditions under which learner-generated illustrations serve as an instructional strategy promoting conceptual change. Specifically, the nature of students' misconceptions and the effects of student-generated descriptive drawings on conceptual understanding of scientific principles associated with the law…

Although the microscope is a basic tool in both physical and biological sciences, it is notably absent from most elementary school science programs. One reason teachers find it challenging to introduce microscopy at the elementary level is because children can have a hard time connecting the image of an object seen through a microscope with what…

Understanding the Sun has challenged people since ancient times. Mythology from the Greek, Inuit, and Inca cultures attempted to explain the daily appearance and nightly disappearance of the Sun by relating it to a chariot being chased across the sky. While people no longer believe the Sun is a chariot racing across the sky, teachers are still…

Students may be slathered with SPF 30 sunscreen all summer at the beach or pool, but what do they know about ultraviolet (UV) light radiation and absorption? The authors of this article found the perfect opportunity to help students find out the science behind this important health precaution, when they developed a series of practical strategies…

This study investigated relationships between students' perceptions of their teachers' interpersonal behaviour and their subject-related attitude in primary science classes in Brunei. Teacher-student interpersonal behaviour was mapped with the "Questionnaire on Teacher Interaction" (QTI) and reported in terms of two independent…

The aim of this study was to detect primary students' conceptions about the origin and conveyance of electric current and about the connection of household electric appliances. In total, 383 students (aged 11-12) from the town of Volos, Greece, participated; 213 of them drawn from experimental classes and 170 from control groups. The results…

The ideas in this article arose from the National Union of Teachers' professional development programme "Putting life into science -- primary science and citizenship" that the author ran with Will Ord from SAPERE. As with other NUT "Teacher 2Teacher" programmes, this course had two major inputs, in January and June, with the intervening time…

The author has developed an innovative science website resource that also shows how engineers use science. As well as addressing scientific facts and concepts, the resource also engages children in the process of scientific enquiry, using graph tools and data interpretation. Part of the resource helps children to understand that much of what they…

In this article, the author focuses on developing scientific reasoning in year 6 children. Having embarked on a series of lessons in which the author hoped to uncover children's ideas about how and why they reason in a particular way, the results were to prove instrumental in developing not only his teaching of scientific enquiry, but also the…
