This study aims to advance the development of the mathematical processing skills of students by suggesting the use of digital geography games. This includes an analysis of its contribution to the standard mathematics curriculum in areas such as data processing as well as its contribution to social studies curricula in areas such as map literacy,…

The field of Data Mining like Statistics concerns itself with "learning from data" or "turning data into information". For statisticians the term "Data mining" has a pejorative meaning. Instead of finding useful patterns in large volumes of data as in the case of Statistics, data mining has the connotation of searching for data to fit preconceived…

The use of strings in BASIC programs is discussed as making the programs more versatile, easier to adapt, and more user-oriented. (MP)

Presents a sample lesson plan (suitable for grades 6-10) and examples of other problems useful in teaching data processing skills. The plan (focusing on planning investigations, data collection, and data processing) is based on the Data Processing Operation Guide, a 10-step model of intellectual operations that can be used in problem solving. (JN)

A computer program that performs the computations involved in recording and averaging grades is presented and described. It can combine homework, in-term tests, and a final examination. The program is written in BASIC. (MP)

Results are reported from a study examining computer usage in high schools that have had computer facilities for many years. (MP)

Discusses two mathematical ideas that come from the Incan and Mayan cultures: (1) the quipus, an Incan recordkeeping tool that encoded data via a logical-numerical system on spatial arrays of colored, knotted cords; and (2) the link between recording time and counting in the Mayan culture. (MDH)

Describes the use of the Apple Macintosh and MULTIPLAN spreadsheet to record and analyze test data. Provides step-by-step instructions on data entry, item difficulty and discrimination calculations, test reliability, score distribution, and graphing of distributions. (JM)

Illustrates how teachers or students can use spreadsheets. Shows the layouts, formulas, and data of two cases: budget manager and data manager. Seven references are listed. (YP)

Cryptography is the science that renders data unintelligible to prevent its unauthorized disclosure or modification. Presents an application of matrices used in linear transformations to illustrate a cryptographic system. An example is provided. (17 references) (MDH)
