This volume contains three teacher-developed units for eleventh grade mathematics students. It serves as an introduction to logarithms, matrices, and functions. Units include statements of objectives, content discussions, worksheets, and exercises. In the logarithm unit the emphasis is on calculation, while in the matrices and functions units…

INTERTAIL, the computer program which implements an approach to tailored testing outlined by Cliff (1975), was examined with errorless data in several Monte Carlo studies. Three replications of each cell of a 3 x 3 table with 10, 20 and 40 items and persons were analyzed. Mean rank correlation coefficients between the true order, specified by…

The last 13 of 32 exercises of a course designed to give a wide range of skills in deductive, inductive, and indirect methods of proof in geometry are presented. (MP)

Socio-political forecasting, a new dimension to university planning that can provide universities time to prepare for the impact of social and political changes, is examined. The four elements in the process are scenarios of the future, the probability/diffusion matrix, the profile of significant value-system changes, and integration and…

The multitrait-multimethod matrix technique, as compared to analysis of variance decomposition, provided a more precise picture of the validity and methods bias characteristics of a longitudinal data set. Data were derived from a three year study of British elementary children to inspect the relationships among three academic traits, as assessed…

It is shown that, by taking as the basis unit vectors along the sides of an equilateral triangle, certain isometric transformations can easily be determined in matrix form. (MN)

This study examined the effect of type of correlation matrix on the robustness of LISREL maximum likelihood and unweighted least squares structural parameter estimates for models with categorical variables. The analysis of mixed matrices produced estimates that closely approximated the model parameters except where dichotomous variables were…

Discusses whether a map can be constructed using only the distances between 15 selected cities. Concepts used in the discussion come from geometry, matrix theory and trigonometry. (PK)

The International Adult Literacy Survey (IALS) was conducted in 1994 in seven European countries with the aim of producing literacy profiles to be used in individual national analyses as well as in international comparisons. It was assumed that the test items could be divided into three unidimensional scales corresponding to the aspects…

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.…

A multitrait-multimethod matrix containing two methods of measuring 12 personality traits was analyzed and confirmatory factor analysis was applied to the data. Although unexplained variance remained, method factors and a general personality factor significantly improved the fit of a model containing only trait factors. (Author/RL)

The authors propose a matrix for a comprehensive approach to cognition and aging. The dimensions of the matrix are (1) biological, psychological, and social factors; and (2) the information processing variables of input, processing, and output.

This theoretical model for message design directs the designer to design a block of time that optimizes the information load and message complexity within the constraints of the receiver's abilities and experience, the requirements of the source, and the capabilities and limitations of the medium. (Author/JEG)

This unit on coding discusses such topics as redundancy, hamming distance, linear codes, and the location of errors. Extensive use is made of matrices and binary numbers. (MP)

Presents a lesson that teaches number patterns through the Vedic matrix found in Vedic mathematics from India. (KHR)
