Describes the use of a student-designed questionnaire to generate data for teaching statistical procedures and concepts. Maintains that students learn firsthand that data analysis is an integral part of the research process. Concludes that students find real data more interesting. (CFR)

Described is a simple electronic interface that can receive signals from up to four analog sensors and four event detectors and save the data on disk. Schematic diagrams, construction details, sample temperature plot and weather station logging programs, and a parts list are included. (KR)

Describes a study that used transaction log analysis to investigate the use of subject searching in the University of California's Online Union Catalog, MELVYL. Mathematical models of trends and patterns in the data are presented, problems with subject searching are explained, and remedies to subject searching problems are suggested. (62…

Discussion of science and math instruction for elementary and secondary students highlights the use of microcomputer-based laboratories (MBL). Data collection, storage, and display are discussed, the use of databases to organize and manage information is described, and the exchange of ideas with other students through telecommunications is…

Describes an activity in which students examine hypothetical exposure to toxins by being showered by different colored pieces of confetti over several visits to exposure sites. Students record quantities of confetti that stick to packing tape. Colors correspond to different toxins posing different health problems. Students process their findings…

Achievement test scores were analyzed in relation to individual- and school-level factors in a national sample of 10th graders (n=2,535) to investigate the relative importance of school and individual factors in determining science learning. Hierarchical linear analyses showed that individual measures accounted for most of the variance. Previous…

This study shows how users access relevant information in a visualized document space and determine whether BiblioMapper, a visualization tool, strengthens an information retrieval (IR) system and makes it more usable. BiblioMapper, developed for a CISI collection, was evaluated by accuracy, time, and user satisfaction. Users' navigation…

In a collaborative project, two mathematics education professors, a third-grade teacher, and her students collected information from the students as they thought through how to ask, collect, and then answer their own data-driven questions. Findings indicated the students exhibited a growing understanding, sophistication, and comfort with the use…

Discusses the development of a data analysis activity used with 8th grade students at the beginning of the school year. Groups of students collected a variety of data about a specific population. (DDR)

Several Colorado schools hired data analysts to help with school improvement efforts. The analysts are teachers who participate on school leadership teams and who support school action research teams. They collect and organize baseline data, help teams measure results of proposed changes, and evaluate results after implementation. Because they are…

The Pennsylvania Department of Education (PDE) is working with local education agencies throughout the Commonwealth to create a culture of teaching and learning in every school that is student-centered, data-informed, personalized, and results-focused. Each of these elements have been supported seamlessly by systems, resources, technology, and…

This study reports the results of a comprehensive survey (59 fixed and 3 open-ended response items) of a stratified (by grade) random sample of K-5 teachers in Indiana (n = 594; response rate = 49.5%).
