This study assessed the representations of nature of science (NOS) in high school chemistry textbooks and the extent to which these representations have changed during the past four decades. Analyses focused on the empirical, tentative, inferential, creative, theory-driven, and social NOS, in addition to the myth of "The Scientific Method," the…

In today's increasingly polyglot classrooms, interpersonal and inter-group conflicts often arise out of mutual misunderstandings between different collections of students, some based on language or status differences but many more generated by emotionally charged misconceptions. As such, peer mediation and peaceful solutions to student arguments…

Nanotechnology is viewed by those in favor of its development in two different ways, and the divide is not recent. This article describes the origins of the differing visions of nanotechnology and examines their broader impacts. The typical history of the field tells nothing about these differing visions, which perhaps misleads. At least two…

The aims of this study were considered under three headings. The first was to elicit misconception that science and physics student teachers (pre-service teachers) had about the terms, "inertial mass", "gravitational mass", "gravity", "gravitational force" and "weight". The second was to understand how prior learning affected their misconceptions,…

The purpose of this study was to investigate the effects of tutorial and edutainment design of instructional software programs related to the "cell division" topic on student achievements, misconceptions and attitudes. An experimental research design including the cell division achievement test (CAT), the cell division concept test (CCT) and…

Background: In 2004, in an attempt to address the current obesity epidemic, the United States Department of Health and Human Services announced a strategy to focus on educating the public on the concept of energy balance. The premise of "Calories Count" was that energy balance is primarily a function of calories in (energy in food)…

The goal of this project was to help science teachers shift to a more inquiry-based teaching style by supplying learning tools that support a more student-centered approach. The project employed PSI (Personal Study Instrument) Sim Modules, a simulation-based electronic learning environment designed to address misconceptions in middle school…

The incidence of autism spectrum disorders has increased dramatically over the past two decades, yet these disorders are still poorly understood. By considering the viewpoints of autistics themselves, together with evidence from the scientific literature, it becomes clear that autism spectrum disorders are not always the debilitating conditions…

In this paper, we explore the use of isomorphic problem pairs (IPPs) to assess introductory physics students' ability to solve and successfully transfer problem-solving knowledge from one context to another in mechanics. We call the paired problems "isomorphic" because they require the same physics principle to solve them. We analyze written…

Energy-yielding metabolism is an important biochemistry subject that is related to many daily experiences and health issues of students. An adequate knowledge of the general features of EYM is therefore important, both from an academic and social point of view. In a previous study, we have shown that high-school students present the misconception…

This study compares 3rd-grade elementary students' gain and retention of science vocabulary over time in two different classes--"connected science instruction" versus "direct instruction." Data analysis yielded that students who received connected science instruction showed less gain in science knowledge in the short term compared to students who…

Mathematics and science are important for success in school, but learning mathematics and science can be a difficult task to some students. Efforts to improve students' learning of school mathematics and science have led to reform efforts in curriculum and instruction over the past decades (e.g., National Council of Teachers of Mathematics [NCTM],…

Established in 1983 by a group of parents and teachers, the 'Aha Punana Leo ('APL) was formed. A grassroots organization, 'APL was established to respond to the dismal plight of the Hawaiian language. Just a mere 25 years ago, the Hawaiian language was on the verge of being lost forever. Through the dedicated efforts of a small group of friends…

The purpose of this qualitative case study was to discover ways in which community college faculty and administrators can better facilitate learning for students with disabilities. Semi-structured interviews, preinterview questionnaires, and a review of relevant documents were used to gain an understanding of how community college faculty perceive…

"Focus in Grade 1: Teaching with Curriculum Focal Points" describes and illustrates learning paths for the mathematical concepts and skills of each grade 1 Focal Point as presented in Curriculum Focal Points for Prekindergarten through Grade 8 Mathematics. It includes representational supports for teaching and learning that can facilitate…
