A nonparametric multicategorical model for multiple-choice data is proposed as an extension of the binary spline model of J. O. Ramsay and M. Abrahamowicz (1989). Results of two Monte Carlo studies illustrate the model, which approximates probability functions by rational splines. (SLD)

Discussion of graphing software for educational purposes focuses on a study in which three versions of an original computer graphing program were used by inner-city high school students to solve scientific data analysis problems. Variations in degrees of flexibility and feedback in the software are explored. (Contains 37 references.) (LRW)

A list of potential writing ideas and general guidelines to be used in integrating writing into the mathematics classroom are provided. Ideas under the headings of narrative, descriptive, and expository writing are included. (KR)

Item parameter estimates derived through item response theory methods have been considered relatively robust to changes in item position and context, but the anomaly in reading scores from the 1986 National Assessment of Educational Progress (NAEP) illustrates problems with common population equating procedures when there are test form changes.…

An experiment in which students collect and analyze data on the population size of a real organism rather that on a model is presented. The activity allows for the integration of mathematics, graphing techniques, and the use of computers. The lesson is designed to follow the learning cycle format. (KR)

Discusses the need at the University of Southern Mississippi library to review resource allocations among serials, monographs and standing orders, and to select an allocation formula. The supply and demand formula used, its implementation, and results in departmental purchasing power are described. (four references) (EA)

Discusses the findings of multicultural research using the Learning Style Inventory and the Productivity Environmental Preference Survey. Differences in learning style among students and young adults of differing ethnic groups, between male and female students, between high achievers and underachievers, and between the gifted and nongifted are…

A conceptual approach and a set of computer simulations are presented to demonstrate that random measurement error in the pretest does not bias the estimate of the treatment effect in the regression-discontinuity design. Focus is on the case of no interaction between pretest and treatment on posttest. (SLD)

Examples of composite functions present students with intriguing questions that they can explore using calculators and computers, geometric and algebraic methods, and approximation techniques. Student-centered activities allow students to make discoveries about functions. (MLN)

Details theoretical and practical uses for Statistics Canada's E-STAT CD-ROM in helping preservice teachers explore the local communities in which they are to teach. Claims that E-STAT allows users to learn mapping and graphing skills and to confront their preconceptions about particular locales. Notes possible uses in social studies instruction.…

Describes projects in a fifth grade classroom that used data collection and graph making activities as part of a collaborative project between the teacher and the library media specialist. Discusses the use of Excel spreadsheets, comparing the effectiveness of different types of graphs, and project planning. (LRW)

Data loggers use sensors to collect environmental data that can be graphed instantly via computer software. A study used four groups of British elementary students to determine the educational benefits of data logging in field situations. Results indicate that data loggers excited the pupils and saved them time recording temperature readings. That…

R. Douglas Greer's "Designing Teaching Strategies" is an important book directed to advanced students in applied behavior analysis for classrooms. This review presents some of the striking features of the Comprehensive Applied Behavior Analysis to Schooling (CABAS[R]) program and the individualized instruction that the book advances. These include…

Effects of a student with severe emotional/behavioral disorders (SEBD) graphing her own performance data on rate of correct words read per minute were evaluated using a withdrawal of treatment case study design. The student recorded her daily performance using a desktop computer and standard spreadsheet software that automatically graphed each…

Coordinate graphs of time-series data have been significant in the history of statistical graphing and in recent school mathematics curricula. A survey task to construct a graph to represent data about temperature change over time was administered to 133 students in Grades 3, 5, 7, and 9. Four response levels described the degree to which students…
