Demonstrates how a technique involving contrastive rhetoric can help writing teachers and their students uncover and improve the overall rhetorical patterns in student writing. In addition, the use of a matrix that locates rhetorical patterns not followed in typical English patterns is described. (11 references) (GLR)

Describes a process model that can be used for performance technology and discusses differences between it and an instructional technology process model. Five basic steps are examined: needs assessment/analysis; design; development; implementation; and evaluation. An instructional technology/performance technology process comparison matrix is also…

Presents a method for using matrix algebra and computers to encode and decode secret messages. Provides examples of coding procedures, a short review of matrix multiplication, and a BASIC program for use with secret messages containing up to 1000 numbers. (RT)

Discusses the value and use of management case studies in library and information science education and provides an analysis of case studies that have appeared in "Library Journal." Type of library is indicated, including public, academic, and special; and management issues involved are identified. (18 references) (LRW)

A way for students to refresh and use their knowledge in both mathematics and physics is presented. By the study of the properties of the "Runge-Lenz" vector the subjects of algebra, analytical geometry, calculus, classical mechanics, differential equations, matrices, quantum mechanics, trigonometry, and vector analysis can be reviewed.

A team-developed sociomatrix coding sheet was used to classify behaviors seen on videotaped small-group teaching sessions held at the end of patient-care activities. Although the sociomatrix appears to have potential to relate specific leader behavior to residents' feedback on subjective learning outcomes, the number of observations was too small…

The student assessment tasks identified by administrators in a previous study (J. C. Impara, B. S. Plake, and J. J. Fager, 1993) as tasks they performed are crossed with the knowledge, skills, and abilities identified as requirements of administrators to perform those tasks. The resulting matrix may be useful in designing instructional programs.…

Although the process of doing social network analysis (SNA) is similar to traditional research and evaluation design, it is in the details that the two traditions diverge. This article describes two areas of differences: (1) the framework for doing SNA; and (2) data collection, analysis, and specific measures. SNA is about relationships and how to…

In traditional factor analysis, the variance-covariance matrix or the correlation matrix has often been a form of inputting data. In contrast, in Bayesian factor analysis, the entire data set is typically required to compute the posterior estimates, such as Bayes factor loadings and Bayes unique variances. We propose a simple method for computing…

The development of a scoring tool to be used with alternative and authentic assessment strategies is discussed, describing the parts of such a tool and the development process. The design is based on the Innovation Configuration (IC) process of the Concerns-Based Adoption Model. To begin, components of the test task are identified. Variations that…

C. L. Olson (1976, 1979) suggests the Pillai-Bartlett trace (V) as an omnibus multivariate analysis of variance (MANOVA) test statistic for its superior robustness to heterogeneous variances. J. Stevens (1979, 1980) contends that the robustness of V, Wilk's lambda (W) and the Hotelling-Lawley trace (T) are similar, and that their power functions…

The traditional concept of validity divides it into three separate types; content, criterion, and construct validities. This view is fragmented and incomplete, failing to take into account evidence of the value implications of score meaning as a basis for action and of the social consequences of score use. The new unified concept of validity…

Love is among the most fundamental aspects of the experience of being human, but measures of perceptions of the experience of love have only recently been explored. One of the most popular measures was developed by C. Hendrick and S. Hendrick. Most previous studies of the measure have used exploratory factor analysis and orthogonal factor…

Many researchers recognize that factors can be rotated obliquely, yielding factors that are correlated with each other. However, not as many researchers realize that this interfactor correlation matrix can then also be factor analyzed. This "higher-order" factor analysis has many useful applications and, in fact, some researchers suggest…

Published by the state of North Carolina, the purpose of this booklet is to assist teachers as they plan instruction to help students become proficient readers. The booklet contains matrices for comprehension, word identification, and instructional strategies to assist in planning and helping students be successful on the End-of-Grade (EOG) Tests…
