A study compared the effects of different methods of analyzing trends to illustrate how failure to account for change in classification will lead to misinterpretation of data on the performance of students with disabilities. Data from five years of assessment in Texas is used to illustrate effects of classification changes. (Contains references.)…

This article explores how knowledge-discovery applications can empower educators with the information they need to provide anticipatory guidance for teaching and learning, forecast school and district needs, and find critical markers for making the best program decisions for children and youth with disabilities. Data mining for schools is…

This paper emphasizes that good teacher-evaluation systems must vary in the kinds of data sources that are used for each teacher within the same personnel-evaluation system. Presents a literature review that shows such variable data systems are technically defensible. The paper examines variable data sources in relation to the "Personnel…

The residents of Galiano Island, British Columbia, have used geographic information systems (GIS) to create a local information database that informs community decisions about sustainable use of forest land. The islanders' involvement with GIS promotes a democratic land-use planning process that is reasoned and well informed. (SV)

Getting answers to questions about schools and student learning requires that educators know how to collect, analyze, and interpret data. Six critical steps in this process include: posing questions, establishing judgment criteria, making a plan, gathering data, analyzing data, and interpreting results. These steps can serve as a beginning guide…

Fournier, coordinator of the School Achievement Indicators Program (SAIP), claims that score differences are associated with linguistic and gender differences. These results have long been substantiated. The expectation-setting process has little reliability or validity. SAIP does not help teachers, and should not determine what students learn.…

Introduces a prototype system for devising and using a metadata vocabulary for data retrieval, based on a project at the United States Department of Agriculture. A unified information-access system called REEIS (Research, Education, Economics, Extension Information System) is being designed to provide a knowledge base of programs, projects, and…

Describes the use of Spotfire, a starfield visualization tool, to generate interactive visualizations of log data, ranging from aggregate views of all Web site hits in a time interval to close-ups that approximate the path of a user through a site. Highlights current efforts and provides examples of the visualizations created in Spotfire.…

Describes an exercise designed to allow for student introductions at the beginning of a new semester while simultaneously revealing ways in which research questions can be constructed to collect data. (WRM)

Discusses development of indicators for the safety of children in out-of-home care using administrative data from the Illinois Department of Children and Family Services. Reports rates of abuse and neglect from 1996 to 1999, and presents an alternative that accounts for the length of time children are exposed to abuse or neglect. (JPB)

Explores methodological issues associated with gaining access to street children and reducing the influence of the researcher's 'outsider' identity, when undertaking sociospatial research. Illustrates how meaningful results can be gleaned without the inhibitory effects of limited access and outsider influence. (Author)

Focus of school-finance litigation has shifted from equity to adequacy. Discusses two recent North Carolina school-finance cases dealing with the concept of educational adequacy: "Leandro," decided by the North Carolina Supreme Court in 1997, and "Hoke County Board of Education," decided by the Wake County Superior Court in…

Assessment methods adapted from qualitative research including ethnographic interviewing and journal writing were applied to the case of an adult with aphasia. By analyzing reports of the client and significant others over the course of treatment, changes in social participation and psychosocial well being were documented. These descriptive data…

In this article, the authors present a classroom experiment that was developed to introduce middle school learners to the carbon cycle. The experiment deals with transfer of CO[subscript 2] between liquid reservoirs and the effect CO[subscript 2] has on algae growth. It allows students to observe the influence of the carbon cycle on algae growth,…

Building and racing mousetrap cars is a common activity in many eighth- and ninth-grade physical science classrooms. However, once students have raced their cars, most mousetrap assignments come to an end. In this article, the authors developed a project to help teachers get more mileage out of mousetrap cars. The Mousetrap Car Project addresses…
