Experiments, as we all know, are especially important in science education. However, their impact on improving thinking could be even greater when applied together with the methods of inquiry-based learning (IBL). In this paper we present our observations of a high-school laboratory class where students used computers to carry out and analyse real…

How do teachers help students realize their place in the universe? How do they teach the relationship among the Earth, Moon, stars, and galaxies during daylight hours? Most teachers assume that astronomy is a difficult subject to teach in the classroom and that without a planetarium little can be learned. In this article, the authors discuss…

Oranges, flying disks, pool noodles, and polyvinyl chloride (PVC) pipe may seem like items discarded after a Rube Goldberg experiment, but in fact, these objects were used in teaching science, technology, engineering, and math (STEM). This article describes a project in which The Center of Ocean Sciences Education Excellence SouthEast (COSEE SE)…

Do-It-Yourself (DIY) Science Kits provide sets of science equipment, including worksheets and/or teachers' guides, and are valuable science resources for poorly equipped schools, particularly those located in geographically isolated areas. This paper reports an investigation of how four teachers in four different schools used an Astronomy Science…

Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…

This longitudinal study reports the results of a replication of "Tutorials in Introductory Physics" in high schools of a Latin-American country. The main objective of this study was to examine the suitability of "Tutorials" for local science education reform. Conceptual learning of simple resistive electric circuits was…

Inspire your students to become detailed observers by encouraging the use of magnifiers. Magnification can make us see an object with new understanding. Rachel Carson said, "Some of nature's most exquisite handiwork is on a miniature scale, as anyone knows who has applied a magnifying glass to a snowflake"(Carson 1965). The lesson described here…

This study focuses on the availability and use of Science Laboratories at the secondary education level in Visakhapatnam District of Andhra Pradesh, India. It is commented that most of the schools do not possess well equipped laboratories and even when equipment is available some science teachers are not utilizing the laboratory facilities.…

As educators, we are always deciding what experiences we want to give students in order to achieve our goals of developing science process skills. One of the best ways of teaching about observation is described here. Using a hand lens and an illuminated pocket microscope, students observe an object at three different levels of…

In a context-aware ubiquitous learning environment, learning systems can detect students' learning behaviors in the real-world with the help of context-aware (sensor) technology; that is, students can be guided to observe or operate real-world objects with personalized support from the digital world. In this study, an optimization problem that…

Did you know that some strong little cylindrical magnets available in local hardware stores can have an effective circumferential current of 2500 A? This intriguing information can be obtained by hanging a pair of magnets at the center of a coil, as shown in Fig. 1, and measuring the oscillation frequency as a function of coil current.

While it is a commonplace in the historiography of electricity that itinerant lecturers and instrument makers were "somehow" part of the "electrical flare" of the 18th century, very little is actually known about them, about their background, their careers and their self-understanding. Yet, research focusing on these…

Describes the basic principles of setting up an aquarium and gives hints on its use as an instructional aid in elementary classrooms, both in generating biological questions and investigations and in its use in other parts of the science curriculum. (AL)
