Four bootstrap methods are identified for constructing confidence intervals for the binomial-error model. The extent to which similar results are obtained and the theoretical foundation of each method and its relevance and ranges of modeling the true score uncertainty are discussed. (SLD)

Three mathematics software packages, MathCAD, Point Five, and TK Solver Plus, are described and compared. The packages were rated on the accompanying documentation, ease of learning, ease of use, matrix operations, equation solving capability, versatility, use of units, generation of graphs and tables, readability of output, and overall…

An example of real-world data is used to introduce comprehensible and visual images of the data and their attributes and relationships. Stem-and-leaf plots, box-and-whisker plots, and scattergrams are used to encourage prompt recognition of data characteristics and to effect appropriate interpretations and inferences. (JJK)

Describes a study of computer experiences and attitudes as well as computer and math anxiety among MBA students. Previous research is reviewed; gender differences are examined; correlations between specific computer experiences and attitudes are considered; and the relationships of experiences and attitudes with grades are discussed. (Contains 52…

Discusses areas where teachers may harbor mistaken assumptions about their students' understanding when using graphing calculators: (1) confidence and competence with order of operations, (2) integration of algebraic and graphical knowledge, and (3) scaling a graph. (MKR)

Challenges mathematics instructors to use graphing calculator technology in courses designed for non-mathematics majors and offers three types of open-ended problems that can be integrated into a basic skills mathematics curriculum: simultaneous equations, distance problems, and proportions using real data. (MKR)

Presents an overview and discussion of some results of research on the use of graphing calculators organized into the following categories: (1) achievement studies, (2) conceptual understanding, (3) problem solving, (4) classroom dynamics, and (5) future research needed. (29 references) (MKR)

The stochastic interactive activation and competition (SIAC) model of perception is presented and tested using several data sets from previous research. The asymptotic predictions of the SIAC model are compared with those of the fuzzy logical model of perception (FLMP). Evidence favoring the FLMP is reviewed. (SLD)

To investigate the effect on item parameter estimation of pooling the raters' ratings and to examine the information content of 2 types of writing samples, the partial credit model was fit to 2,000 writing samples from secondary students that had been holistically scored. Implications for test construction are discussed. (SLD)

This article describes a social studies project for deaf students, which used the search for information concerning people with deafness to develop student skills in creating and interpreting various kinds of charts and graphs. (DB)

Proposes that state legislatures are a laboratory for mathematics. Discusses the mathematics involved in the three income tax proposals submitted to the Connecticut General Assembly in 1991 and the effects that each plan would have on families. The proposals included a flat rate plan, a graduated rate plan, and a compromise proposal. (MDH)

Tests the effects of number of data points and type of statistical display on time spent answering questions about information. Finds that tables and graphs are more efficiently processed than text presentation of the same data. Suggests that the time variable is a more realistic measure than information recall of cognitive processing effort. (SR)

Describes the use of Charles Minard's graphic of Napoleon's 1812 Russian Campaign as an instructional tool in history classes. Maintains that the graphic, created in 1861, can be analyzed by students to determine six historical and geographical factors involved in Napoleon's defeat. Includes a copy of Minard's graphic. (CFR)

The importance of regression diagnostics in detecting influential data points is discussed, and five statistics are recommended for the applied researcher. The suggested diagnostics were used on a dataset of 24 subjects, and effects were analyzed. Colinearity-based diagnostics and diagnostics for a variety of procedures are discussed. (SLD)

Evaluation of strategic planning programs is illustrated using the examples of statewide forest resource planning programs implemented by state governments in 1986. Client-based perspectives were studied via a survey of 216 officials affected by the forestry planning program. Considering planning's context, process, outputs, and performance helped…
