The changing landscape of science and science education has provided an impetus to re-imagine how science can be taught in schools. The dawn of the Big Data era, especially in astronomy, and the notion of "Science as Practice" are some of the developments driving this need for a re-imagination of science education. This current work…

This exercise encompassed the construction and use of a microcontroller-based laser refractometer. The instrument, which does not require a high skill level to build, primarily consisted of a line laser, optical sensor, several 3-D printed parts and printed circuit boards, and a microcontroller development board. Construction and testing of the…

Some balls which are made of high-quality rubber (an elastomeric) material, such as tennis or squash balls, could be used for the determination of an important property of such materials called resilience. Since a bouncing ball involves a single impact we call this property "rebound resilience" and express it as the ratio of the rebound height to…

Pedagogic Conversational Agents are computer applications that can interact with students in natural language. They have been used with satisfactory results on the instruction of several domains. The authors believe that they could also be useful for the instruction of Secondary Physics and Chemistry Education. Therefore, in this paper, the…

The roles of teachers and students are changing, and there are undoubtedly ways of learning not yet discovered. However, the computer and software technology may provide a significant role to identify the problems, to present solutions and life-long learning. It is clear that the computer based educational technology has reached the point where…

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students' effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work…

We present a new and innovative interface that allows the learner's body to move freely in a multimodal learning environment. The Situated Multimedia Arts Learning Laboratory ("SMALLab") uses 3D object tracking, real time graphics, and surround-sound to enhance embodied learning. Our hypothesis is that optimal learning and retention occur when…

This study investigated novel pedagogies for helping teachers infuse inquiry into a standards-based science curriculum. Using a multi-user virtual environment (MUVE) as a pedagogical vehicle, teams of middle-school students collaboratively solved problems around disease in a virtual town called River City. The students interacted with "avatars" of…

Engaging students in science learning can be challenging, and incorporating new forms of technology into science has been shown to provide creative learning experiences. However most technology enhanced learning and e-Science experiences to date have been designed and run by researchers. There is significant challenge in moving these experiences…

Describes interfacing a hand-held oxygen probe with a microcomputer and suggests experiments for undergraduate chemistry courses that could facilitate student understanding of aquatic environmental processes which involve dissolved oxygen. Data can be analyzed through the program or exported into other software. Presents results of an experiment…

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

Contains an illustration and text to aid in describing the DynaPulse 200M Education Edition microcomputer-based laboratory (MBL), which combines interactive software with curriculum and medical instruction to teach students about the cardiovascular system. Review includes key features of the software, cost, and ease of use. (ZWH)

Presents an experiment on collecting data while measuring the dissolved-oxygen levels in Thames River tap water straight from the water mains and dissolved-oxygen levels in rainwater containing Hornwort water weed over 24 hours. (Author/ASK)

Computers are routinely used to control experiments in modern science laboratories. This should be reflected in laboratories in an educational setting. There is a mismatch between the power that can be delivered by a computer interfacing card or a TTL logic circuit and that required by many practical pieces of laboratory equipment. One common way…

Contained in this issue are 30 articles reviewing advances in different fields of analytical chemistry since 1980. Cumulatively, these reviews list over 1000 references. (CW)
