Investigates how students develop an understanding of chemical representations with the aid of a computer-based visualizing too called eChem that allows them to build molecular models and view multiple representations simultaneously. Involves 11th grade students (n=71) at a small public high school and examines the changes in students'…

Virtual field trips offer a new way for teachers and students to visit historical sites and museums. Most notably, virtual field trips provide access to places that normally would be impossible for classrooms to visit, and this, in turn, provides a plethora of learning possibilities for the classroom. Why should teachers consider creating a…

Technology is a tool that has the potential to empower educational leaders at all levels--whether they are superintendents, principals, teachers, board members or state officials--as well as to redefine what education means in the 21st century. Technology provides more accurate information and advanced communication capabilities. Technology can be…

This paper reports the introduction of electronic handsets, like those used on the television show Who Wants To Be A Millionaire? into the teaching of philosophical logic. Logic lectures can provide quite a formidable challenge for many students, occasionally to the point of making them ill. Our rationale for introducing handsets was threefold:…

This article introduces "medium-based" design -- an approach to creating "exploratory learning environments" using the method of "extending a medium". First, the characteristics of exploratory learning environments and medium-based design are described and grounded in related work. Particular attention is given to "extending a medium" --…

Extracting and applying lessons from history is rarely easy and sometimes risky but there are moments when historical records are so compelling that they rise above mere proof to the level of interocular impact. In this article, the author shares his similar experience while visiting his colleague, Professor Bruce Clark, at the University of…

Greater access to scientific instrumentation, courses, and supporting materials through the Internet and Integrated Laboratory Network (ILN) has the potential to profoundly change the way in which instrumental sciences are taught. Increased access to instrumentation will provide better opportunities for students to learn and practice instrumental…

This review paper examines ongoing research on a range of applications of electronic discussion in a laptop university teacher education program. The findings and challenges of employing electronic discussion are discussed and the authors make a case for selecting instructional models that encourage substantive discussion on the part of the…

Four experienced teachers replaced the traditional classroom dynamics and environment having micromanaged routines with CyberEnglish classroom structure that supports scholars' choices and voices. The lack of voice in students' writing was one of the reasons for the changes in the classrooms and exciting results were achieved with different…

Handheld devices have the potential to make a large impact on K-12 educational settings, due to their relative low cost, high mobility, and interactive learning capabilities. This article, the outcome of a large-scale project examining the use of handheld computers, examines how handheld computers can improve teaching and learning, what…

Where learner discourse has been the focus of much recent research on asynchonous online instruction, the specific forms of instructional discourse used by online educators has yet to be examined. Indeed, the majority of work in the area of foreign language and telecommunications has concentrated on student-student, student-peer interaction, and…

The St. Louis, Missouri Educational Museum has its roots in the 1904 Centennial Exposition, held at Forest Park on the edge of the city. The theme of the exposition was education and technology. Seventy thousand local school children visited the exposition, and at its conclusion an initiative was launched to purchase some of the exhibitions as…

The current emphasis on flexible modes of mathematics delivery involving new information and communication technology (ICT) at the university level is perhaps a reaction to the recent change in the objectives of education. Abstract algebra seems to be one area of mathematics virtually crying out for computer instructional support because of the…

Summary Street is educational software based on latent semantic analysis (LSA), a computer method for representing the content of texts. The classroom trial described here demonstrates the power of LSA to support an educational goal by providing automatic feedback on the content of students' summaries. Summary Street provides this feedback in an…

Using survey data, the authors examined the relationship between intensity (as opposed to duration) of a technology-focused professional development program and specific participant characteristics in predicting successful outcomes. The four participant characteristics chosen were: teachers' feelings of preparedness to support student technology…
