Science becomes engaging when students know that what they learn in the classroom relates to their own lives and communities. This article describes a project in which students use field exploration and online software to design virtual solutions to improve the hydrology of their school yard. The project is called Teaching Environmental…

Chemistry in high school is often presented as a jumbled mass of topics drawn from inorganic, analytical, and physical sub-disciplines. With no central theme to build on, students may have trouble grasping the chemical sciences as a coherent field. In this article, Stowe and Elvey describe an activity that integrates different facets of chemistry…

The article describes the use of Mathematica, a computer algebra system (CAS), in a high school chemistry course. Mathematica was used to generate a graph, where a slider controls the value of parameter(s) in the equation; thus, students can visualize the effect of the parameter(s) on the behavior of the system. Also, Mathematica can show the…

Formal mathematical methods remain, for most high school students, mysterious, artificial and not a part of their regular intuitive thinking. The authors develop some themes that could lead to a radically new approach. According to this thesis, the teaching of programming languages as a regular part of academic progress can contribute effectively…

Less than half of the students in the United States graduate from high school and are ready to take college-level math courses. Many years and varieties of remedial math programs have failed to dramatically improve outcomes, especially at scale. The question we face is whether technology in general, and open educational resources in particular,…

The prototype of a guided practice application was developed to instruct year 13 biology students in the process of DNA replication. The application uses a high degree of interaction to engage the student in a guided exploration and problem solving exercise. An evaluation revealed that the students showed considerable enthusiasm and significant…

Recent developments in digital rights enablement for video, plus inexpensive purpose-built applications such as the Media on Demand system, are now adding video to the montage of rich media objects for learning online. Video libraries and repositories can be customized and stored on local servers for access by place-based or distance learners as…

This paper discusses the development of computer-based business simulations designed to prepare high school students for entry-level jobs in business, and explores the implementation of feedback mechanisms in simulations. Reasons why simulations are an appropriate type of media for this application, the nature of feedback, and research on feedback…

This article describes practical issues related to the design and the development of a Web-Based Learning Environment (Web-LE) for high school students. The purpose of the Fossilization Web-LE was to help students understand the process of fossilization, which is a complex phenomenon and is affected by many factors. The instructional design team…

An effective learning environment must ensure that students are motivated to access whatever information is available, that they have an authentic context in which to situate that knowledge, and that they face challenges that allow them to put that knowledge to use. In an attempt to address these issues, a computer program was developed, called…

This article describes how a K-12 school in South Florida adopted a course management system with e-portfolio capabilities. E-portfolios are available tools, though more costly, in higher-end course management systems and are gaining recognition in the K-12 market. However, according to a recent survey administered by the technology team at the…

In fall 1997, the University of Wisconsin-Whitewater (UWW) provided Science and Technology in Society, a university general studies science literacy course, to advanced placement high school students at three local high schools, using a combination of live video presentations and World Wide Web (WWW) courseware. A total of 26 high school students…
