This research examined discourses in classroom and online learning environments where the Knowledge Building Community model was enacted to foster deep understanding in science learning in Singapore primary classes. This study posited that discourse is a fundamental form of learning that reveals how knowledge building is enacted and embodied by a…

The purpose of this study was to investigate whether conceptual change texts and laboratory experiments are effective in overcoming misconceptions and whether the concepts were acquired permanently when these methods were utilized. In this study, we addressed some topics from the "Matter and Change" unit in science and technology class of…

The popularity of massively multiplayer online role-playing games (MMORPGs) has grown enormously, with communities of players reaching into the millions. Their fantasy narratives present multiple challenges created by the virtual environment and/or other players. The games' potential for education stems from the fact that players are immersed in a…

In this integrated inquiry, students in an elementary teaching methods class investigate a real-world problem outside the classroom. The students use the Cognitive Research Trust (CoRT) thinking strategy to find the causes of, impact of, and possible solutions to the problem. They present their findings and then discuss implementation of this…

This study examines the process by which a teacher may be able to answer a question asked in the classroom by using a scientific approach and a simple activity. This article examines a discussion of the question "Is space light or dark?" Priority in the discussion has been given to determining students' preconceptions about the interaction of…

"Ducks in the Flow, Where Did They Go?" represents a fusion of language, arts and science. Offering both a story of discovery and factual science content, this hybrid storybook/textbook promotes literacy on several fronts: ocean principles, general science, and language/arts. A step up from the average text or reference book, "Ducks in the Flow"…

As we contemplate on teacher identity research, there is a need to place a teacher's narratives or story-lines at the center of that work. In this forum, in response to the insightful commentary from Stephen Ritchie and Maria Inez Mafra Goulart and Eduardo Soares, I place a greater emphasis on understanding Daisy's narratives from an existing…

In this study we examined the effects of syntactic and lexical complexity on third-grade students' comprehension of science texts. A total of 16 expository texts were designed to represent systematic differences in levels of syntactic and lexical complexity across four science-related topics ("Tree Frogs, Soil, Jelly Beans and…

The study investigated teachers' involvement in implementing the basic science and technology curriculum in primary schools in WSLGA (Warri South Local Government Area) of Delta State. It sought to identify the availability of the document in primary schools and teachers' knowledge of the objectives and activities specified in the curriculum.…

Reform-oriented science teaching with a specific focus on evidence and explanation provides a student-centered learning environment which encourages children to question, seek answers to those questions, experience phenomena, share ideas, and develop explanations of science concepts based on evidence. One of the ways schools have risen to meet the…

Outdoor educational programmes are generally believed to be a suitable alternative to conventional biology settings that improve participants' environmental attitudes and knowledge. Here we examine whether outdoor educational programmes focused solely on practical work with plants influence participants' knowledge of and attitudes towards plants.…

What students and teachers often ask is, how are nano-sized materials made when they are so small? One answer is through the process of self-assembly in which molecules, polymers, and nanoparticles connect to form larger objects of a defined structure and shape. Two hands-on experiments are presented in which students prepare capsules in real time…

The central focus of this study was the development, use and evaluation of CD-ROM picture books in elementary school science teaching. Three CD-ROM picture books based on the Campus Insects unit from the new elementary school science curriculum in Taiwan were developed. A quasi-experimental method was used to compare the use of the CD-ROMs and…

From the time they are born, children have a natural curiosity toward the world around them. Even though they can't speak, one can still observe that they are skilled at discovery. Science fair projects can nurture this natural curiosity and give elementary students the opportunity to explore their interests in a rewarding way. Participation in a…

The discovery or re-construction of scientific explanations and understanding based on experience is a complex process, for which school learning often uses shortcuts. On the basis of the example of analyzing real seismic measurements, we propose a computer-facilitated collaborative learning scenario which meets many of the requirements for…
