Uses earthquakes to teach about the importance of collecting enough data and simplifying and visualizing them appropriately. Leads students relatively easily into a sophisticated yet enjoyable examination of large databases and creating hypotheses to explain the patterns that they unearth. (Author/NB)

Discusses the role that information resource management (IRM) plays in educational program-oriented budgeting (POB), and presents a theoretical IRM model. Highlights include design considerations for integrated data systems; database management systems (DBMS); and how POB data can be integrated to enhance its value and use within an educational…

Describes Structured Query Language (SQL), the result of an American National Standards Institute effort to standardize language used to query computer databases and a common element in second generation database management systems. The discussion covers implementations of SQL, associated products, and techniques for its use in online catalogs,…

In Lapland, a project investigated the effectiveness of multiform teaching (classroom instruction, distance teaching, various media, and linking of instruction to working life) to train data processing experts. Evaluation showed the necessity of adequate facilities and equipment, the importance of phone contact, and the need for teachers to be…

Presents an attempt to develop an integrated overall management information system growth and integration theory for small organizations. The three dimensions that facilitate information integration progress (i.e., electronic data processing evolution, computerized tools, and user types) are presented, analyzed, and characterized. Guidelines for…

Discusses the shift of information access from a data-centered to a user-centered model and describes the Daltext system, a prototype user-centered information system that allows the user to determine how the data will be viewed (i.e., within a datastream model, a set model, a relational model, and/or a hierarchical model). (Contains 30…

Describes a method of selective information presentation exemplified by an editor that produces an encyclopedia based on source articles, and needs access to dynamically-selected aspects of the articles for editorial decision making. Presents a system that provides a generic basis for summarization by building multilingual, genre-driven automatic…

Examines the possibility of using expert system tools for environmental data management. Describes the domain-independent expert system shell SAK and Knowledge EXplorer, a system that learns rules from data. Demonstrates the functionality of Knowledge EXplorer on an example of water quality evaluation. (LZ)

Includes "Learning by the Numbers" (Oliver); "Industrial Control through Electronics" (Cowen, Haynie); "Data Control with a PC" (Zoghi, Lorenzo); "Portfolio Assessment" (Wolansky); and "Quality in the Classroom: Evaluating Individuals in Group Projects" (McCrea). (SK)

The Electronic Data Transfer (EDT) network for Connecticut local school districts encompasses nine major databases and provides dozens of online data reports to network users. At a low cost and high degree of success, EDT has improved the data collection and reconciliation process at the state and local levels and generated a capacity for…

Applying prospect research techniques to donors on the college or university annual fund rolls can be effective without high cost. Simple segmenting can be done by manipulating existing computer files, as illustrated by the experience of a number of institutions. Using commercial analysis services can also be cost effective.

Introduces the multicharacter trie as an index structure that can improve the time needed for retrieving full-text materials stored on CD-ROMs. The advantages of this structure compared to other structures are described, and experimental results comparing it to the widely used B+ tree and other structures used for full-text retrieval are…

Describes a project implemented in a second-grade class that is based on a child-centered, problem-solving approach to connecting literature and writing with mathematics. Emphasizes data exploration by having students collect, record, interpret, and analyze data on eggs. Contains 11 references. (ASK)

Describes a process of data collection with young children using the outdoors as a mathematical context. The process of data collection and processing introduces children to more abstract mathematics as they sort and classify data, create graphs, compare datasets, examine patterns, and interpret graphical representations. (ASK)

Defines data mining and the three categories of data mining models: classification, clustering, and associations and sequencing. Discusses how specific text mining, knowledge management, and search engine vendors are developing products that will take the Web to the next level. (AEF)
