Oversampling and cluster sampling must be addressed when analyzing complex sample data. This study: (a) compares parameter estimates when applying weights versus not applying weights; (b) examines subset selection issues; (c) compares results when using standard statistical software (SPSS) versus specialized software (AM); and (d) offers…

One size does not fit all. For anyone who has ever tried to make something fit (especially when it won't), it's best to realize that the word "all" does not really mean "everyone." The same thing is true for subscription databases. While it might seem that all students in grades K-12 can benefit from the use of the database contents, in reality,…

This paper presents two nine-year-old children who used different oral, written, visual, and digital modes as resources to create meaning and to position themselves socially through multimodal stories. Their diverging experiences with technology as a resource for storytelling draw attention to the importance of studying "the ways that old and new…

In this article, the author, an information technology librarian at Georgian Court University (GCU), recounts how she accomplished technology tuneup at GCU by looking at the existing systems and matching them up with the library needs to find no-cost solutions. The first and biggest tuneup was to the engine, the Sirsi Unicorn integrated library…

Simulations make it possible to explore physical and biological phenomena, where conducting the real experiment is impracticable or difficult. The implementation of a software program describing and simulating a given physical situation encourages the understanding of a phenomenon itself. Fifty-nine students, enrolled at the Mathematical Methods…

While the importance of "expressive writing," or informal, self-directed writing, has been well established, teachers underutilize it, particularly in technical writing courses. We introduce the term expressive/exploratory technical writing (XTW), which is the use of informal, self-directed writing to problem-solve in technical fields. We describe…

Computer-based technologies offer promise as a means to assess students and provide teachers with better understandings of their students' achievement. This article describes recent developments in computer-based and web-based reading and literacy assessment, focusing on assessment administration, information management, and report creation. In…

Mathematical knowledge can be categorized in different ways. One commonly used way is to distinguish between procedural mathematical knowledge and conceptual mathematical knowledge. Procedural knowledge of mathematics refers to formal language, symbols, algorithms, and rules. Conceptual knowledge is essential for meaningful understanding of…

ICT tools have been developed to facilitate web-based learning through and learning about argumentation. In this paper we will present an example of a learning activity mediated by Digalo--software for knowledge sharing through visually supported discussion--developed in a university setting. Our aim is to examine, in particular, socio-cognitive…

The paper describes a classification system for adaptive methods developed in the area of adaptive educational hypermedia based on four dimensions: What components of the educational system are adapted? To what features of the user and the current context does the system adapt? Why does the system adapt? How does the system get the necessary…

Colleges and universities and commercial firms have demonstrated great progress in realizing the vision proffered for "Open Source 2007," and 2010 will mark even greater progress. Although much work remains in refining open source for higher education applications, the signals are now clear: the collaborative development of software can provide…

Interactive whiteboards have made quite a splash in classrooms in recent years. When a computer image is projected on the whiteboard using an LCD projector, users can directly control the computer from the whiteboard. In some systems such as Smart and Mimio, the finger is used in place of a mouse to open and run programs or move windows around. In…

This paper defines Bayesian network models and examines their applications to IRT-based cognitive diagnostic modeling. These models are especially suited to building inference engines designed to be synchronous with the finer grained student models that arise in skills diagnostic assessment. Aspects of the theory and use of Bayesian network models…

This article provides an overview of KidTools, an electronic performance software system designed for elementary and middle school children to use independently on classroom or home computers. The software system contains 30 computerized research-based strategy tools that can be implemented in a classroom or home environment. Through the…

If we intend to teach through educational media, we also have to teach about those media. This article explores the implications of this perspective for the use of computer games in the classroom. It seeks to explain why and how teachers might teach about computer games as a medium in their own right, just as they teach about film or television or…
