Over the past decade, much has been learned about the ocean's secrets and especially about the creatures of the deep sea. The deepest parts of the oceans are currently the focus of many new discoveries in both the physical and biological sciences. Middle school students find the deep sea fascinating and especially seem to enjoy its mysterious and…

State-of-the-art digital cameras open up enormous possibilities in the science classroom, especially when used as data collectors. Because most high school students are not fully formal thinkers, the digital camera can provide a much richer learning experience than traditional observation. Data taken through digital images can make the…

Since the discovery of the DNA double helix (in 1953 by Watson and Crick), technologies have been developed that allow scientists to manipulate the genome of bacteria to produce human hormones, as well as the genome of crop plants to achieve high yield and enhanced flavor. The universality of the genetic code has allowed DNA isolated from a…

Science education has moved from the traditional lecture-and-demonstration model toward a student inquiry model. Inquiry activities allow students to discover many relationships of science for themselves. However beneficial this shift may be, former assessment methods used in the traditional model may no longer effectively determine student…

The concept of energy arises in all disciplines of science, from ecosystems and species niches to gravity and motion. Most students have difficulty understanding the relative sense of energy, however. Unless students are studying thermal energy and using the kelvin scale, the energy of an object or system is always with respect to some baseline or…

Parents' math and science-promotive behaviors predict children's activities and interest in these courses. (Contains 1 table and 2 figures.)

This article describes a variety of opportunities for educational activities that can be found in the complex, yet easy-to-manipulate, trophic relationships between goldenrod plants, insects that induce gall formation, and the natural enemies of these gallmakers. Gall collection, measurement, and observation (exit holes, larval response,…

The "National Science Education Standards" provide a vision and standard of science instruction that includes not only the factual, content-rich history of science but also an understanding of the processes and skills necessary to "do" science. Moreover, the "Standards" provide the framework for science instruction that embodies the use of…

This study investigated preschool science environments in 20 preschool classrooms (N=20) in 13 midwestern child care centers. By operationalizing Neuman's concept of "sciencing," this study used The Preschool Classroom Science Materials/Equipment Checklist, the Preschool Classroom Science Activities Checklist, and the Preschool Teacher…

London Metropolitan University in Islington, North London, is very much part of the local community. A very high proportion of the students come from the areas around the university, and an even higher proportion go on to take up posts in the immediate inner-city environment. The education department was therefore very keen to foster…

At Waite End Primary School in Waterlooville, Hampshire, the authors are involved in a research project with the University of Winchester and the pharmaceutical company Astra- Zeneca called "Teachers and young children exploring their worlds together". The project focuses around their belief that "the younger a child is the more…

Problem solving is an ideal learning strategy, especially for topics that are perceived as difficult to teach. As an example, a format is described for a problem-solving session designed to help students understand the pressure-flow hypothesis of phloem transport in plants. Five key facts and their discussion can lead to the conclusion that a…

It has recently been determined that generating an explanatory hypothesis to explain a discrepant event is important for students' conceptual change. The purpose of this study is to investigate how students' generate new explanatory hypotheses. To achieve this goal, questions are used to identify students prior ideas related to electromagnetic…

Data structures and algorithms are core issues in computer programming. However, learning them is challenging for most students and many of them have various types of misconceptions on how algorithms work. In this study, we discuss the problem of identifying misconceptions on the principles of how algorithms work. Our context is algorithm…

Previous research on infant swimming has reported contradictory findings. Cross-sectional observations revealed a disorganized phase between about 3 and 12 months, which was attributed to "cortical inhibition" and implied slow learning (McGraw, 1939). However, training with a single infant during this period revealed rapid acquisition (McGraw,…
