In the January 2007 issue of "The Physics Teacher," Prentis, Fulton, Hesse, and Mazzino describe a laboratory exercise in which students use a geometrical analysis inspired by Newton to show that an elliptical orbit and an inverse-square law force go hand in hand. The historical, geometrical, and teamwork aspects of the exercise are useful and…

Research Findings: This article focuses on preschool science, an important but under-researched school readiness domain. There is considerable activity surrounding quality science in early childhood classroom practices, including state standards, curricula with science activities, and an extensive literature on potential best practices. However,…

The authors introduced polar science in a fourth-grade classroom by means of 3 hands-on activities that addressed (1) the melting of glaciers and ice, (2) the differences between the North and the South Pole, and (3) the geography and landforms of Antarctica. An assessment 4 months after the original activity showed that students remembered the…

Spurred by concerns about an inadequately sized science, technology, engineering, and mathematics (STEM) workforce, there has been a growing interest in out-of-school time (OST) science activities as a means to foster STEM career interest. This study examines the association between OST science activities and STEM career interest in university…

The purpose of this paper is to describe and analyze the process of construction of meaning about the shape of the Earth and the alternation of day and night, which is inherent to the practice of experimental science teaching. This teaching practice was gradually done by the researcher in a 1st grade class of a Portuguese primary school. The class…

Mixed-method evaluation of two iterations of month-long summer enrichment programs for English-learning secondary students investigated impacts on participants' beliefs about school and academic achievement, and on actual course choices, test outcomes, and graduation rates. Students (N = 85) from one ethnically diverse, high-poverty high school in…

Students with blindness or low vision are often discouraged from full participation in laboratory science classes due to the inadequacy of current methodological approaches and the lack of sophisticated adaptive technologies. Consequently, these students rarely go on to pursue advanced studies and employment in the sciences. In response to his own…

The care and use of animals in education and medical research are very controversial and emotional public issues. Society needs to discuss these issues to reach an ethical stand. A sample of 118 sciences student teachers from a South African university responded to a questionnaire on animal rights and using animals for food, clothes, sport,…

At the University of Pittsburgh, the author and his colleagues have been exploring a range of approaches to design challenges for implementation in high school science classrooms. In general, their approach has always involved students working during class time over the course of many weeks. So, their understanding of what works must be…

This study focuses on the experiences and perspectives of sixth grade girls in a moderately-sized East Coast city as they construct meaning through active engagement in a science classroom and analyzes the ways in which girls change roles and incorporate social interaction during science activities to create their own unique engagement in science.…

Despite many scholars' recommendations, science is often avoided during early childhood education. Among the reasons provided by early childhood teachers for the exclusion of science from their daily routines included science anxiety, low self-efficacy with respect to teaching science, lack of experience participating in science activities as…

The fields of gifted and engineering education share many common interests, and their students share many common attributes. Infusing and making engineering implicit in the K-6 education programs creates opportunities to develop concepts, skills, and habits of the mind that are valuable in all disciplines while providing opportunities to discover…

This study explores the impacts of selected early science experiences in kindergarten (frequency and duration of teachers' teaching of science, availability of sand/water table and science areas, and children's participation in cooking and science equipment activities) on children's science achievement in kindergarten and third grade using data…

This exploratory study examines how a series of laboratory activities designed using a new instructional model, called Argument-Driven Inquiry (ADI), influences the ways students participate in scientific argumentation and the quality of the scientific arguments they craft as part of this process. The two outcomes of interest were assessed with a…

One of the long-standing general undergraduate education requirements common to many colleges and universities is a science course with a laboratory experience component. One of the objectives frequently included in the description of most of these courses is that a student will understand the nature and processes of scientific inquiry. However,…
