The pre-math computer program for preschool children that is described is divided into subprograms representing different basic numerical concepts--discrimination, recognition, and recall--and presents research design used to test the program's effectiveness with Head Start preschool children. Results indicate the program was ineffective…

Online seaches of sample topics in the area of forensic medicine were conducted in the following life science databases: Biosis Previews, Excerpta Medica, Medline, Scisearch, and Chemical Abstracts Search. Search outputs analyzed according to criteria of recall, uniqueness, overlap, and utility reveal the need for a cross-database approach to…

This study reports the cognitive processing of a Year 8 female student (Kerri) during a test, and during her subsequent homework as she consolidated as part of abstracting; a topic of recent research interest. This case adds to the body of knowledge about how constructing and consolidating can occur simultaneously. The analysis captured the…

This book contains an interactive calculator and worksheet program designed to teach the graphing of some of the functions that appear in high school mathematics courses. The graphs of linear, exponential, and logarithmic functions are explored as well as other functions. Activities focus on the graph that appears as a standard part of algebra…

The Rivers Project at Southern Illinois University began in February, 1990 as a pilot program involving eight high schools along the Mississippi and lower Illinois River. The Rivers Project network has grown through the training of teachers from across the United States and Canada. With scientific literacy as the ultimate goal, students collect…

"My Learning Curve" is a visual rapid appraisal technique that was developed in Canada for exploratory use in one of a series of loosely coupled evaluation studies of a redesigned teacher education plan. It is designed to allow teacher candidates enrolled in the program to depict quickly and visually, rather than verbally, their…

Research supported in part by grant MH-07346 from the National Institute of Mental Health, and a grant from the Illinois State Department of Mental Health.

Discusses trade-off analysis, a data collection method with conjoint measurement technique in which respondents rank order a matrix of pairs of levels of specific attributes, and gives examples for use in determining library users' perceptions of relative utility of completeness of information versus cost of a search. Twelve sources are cited.…

Presents new evidence to show that nuclear radiation is associated with impaired cognitive functions. Links changing levels of radiation from U.S. nuclear bomb testing to the long decline--and now the beginnings of a rise--in Scholastic Aptitude Test scores. (Author/RW)

Data on 431 Minnesota school districts' use of the "referendum levy" (above the regular tax rate) and the "discretionary levy" (extending state aided taxes) indicate wealthier districts use the referendum levy more, yielding higher tax rates and more revenue. Referendum levies adjusted through district power equalizing should…

By dividing data from the Higher Education General Information Survey (HEGIS) on over 2,700 institutions into two periods (1972-76 and 1976-79), researchers found that patterns of enrollment variation were related to five institutional types (based on degrees granted, comprehensiveness, and years of study), public or private control, and economic…

The activities presented deal with representing student-collected information by means of reusable teaching aids such as pictorial graphs, tally charts, bar graphs, and circle graphs. Directions for making three of the teaching aids described are included. The activities are seen as supplements to drill and practice. (MP)

A class of seldom-seen real-world applications of high school mathematics is described. The problems considered are viewed as more substantial than ordinary word problems and thus are thought to require a greater commitment of time and energy. Suggestions for student extensions of the project are made. (MP)

Details of a class exploration of graphs that drew upon knowledge about the behavior of particular kinds of functions and applied them in a new context are provided. (MP)
