Estimation is by means of iterative convergence to maximum likelihood estimates, and two approaches to assessing fit of the model to sample data are discussed. Relation of this general probabilistic model to other, more restricted models is explored and three cases of the general model are applied to exemplary data. (Author/RC)

The major objectives of the study "Influence of Institutional Climate Perception on the Professional Aspirations of Teacher Educators" are: (1) To estimate the relationship between professional aspirations and institutional climate perception for the total sample and relevant sub samples; and (2) To test whether the comparable…

This report documents the results of a survey of 1,137 active-duty military families, including activated Reservists, regarding child care use. These survey data were analyzed to estimate the relationship between individual family characteristics and installation characteristics and the probability that the family uses any nonparental child care,…

This book is a guide to the development of mathematical talent in students in grades K through 8. The first chapter is on developing mathematical promise and considers characteristics of students who are mathematically promising, the goals of mathematics instruction, how to find and/or create good problems, models for increasing the numbers and…

In this report, we establish benchmarks of readiness for four common first-year college courses: English Composition, College Algebra, Social Science, and Biology. Using grade data from a large sample of colleges, we modeled the probability of success in these courses as a function of ACT test scores. Success was defined as a course grade of B or…

This paper reports on a mathematics course in an Austrian high school that focuses on probability distributions. Students in this course used a TI-92 during math classes, at home for doing exercises, and during math tests. The TI-92 was used as a tool for calculations and illustrations making the concepts of probability distributions easy to…

This essay investigates whether students who attend higher-quality schools commit fewer crimes. If so, improving school quality might be worth considering as an approach to reducing juvenile crime. The author finds some evidence that higher-quality schools are associated with lower probabilities of committing some types of crime. (Contains 1…

Digital collaborations are often stymied because institutions of higher education are increasingly divided between two cultures: the culture of knowledge and the culture of information. Campuses primarily remain institutions of knowledge, although practices of information acquisition can no longer be ignored, especially since the advent of…

This book provides a resource for mathematics teachers to understanding the National Council of Teachers of Mathematics' (NCTM) standards and implementing these standards in their teaching. Five standards are overviewed: (1) number and operation; (2) algebra; (3) geometry; (4) measurement; and (5) data analysis and probability. Lesson plans are…

This collection of activities is designed to show how graphing calculators can be used to explore statistics. The activities address such topics as data representation, distributions, and statistical tests. Teaching notes and calculator instructions are included as are blackline masters. (MM)

The conference centered on three main threads: (1) learning and the choice of materials; (2) the return to arithmetic; (3) topics (applications, geometry, probability, computers). Capsule summaries of the papers read and the ensuing discussions are presented. (JP)

Mathematics in nature and in the technological world is discussed. Outdoor activities with mathematical content are listed. (JP)

The present study operationally defines selective attention in terms of tactile observing responses measured by percentage contact time per trial to the relevant stimulus dimension, and investigates the changes of these responses in a discrimination shift paradigm under the effect of overlearning.

A major problem in most predictions of school enrollment is the forecaster's failure to express adequately his certainty or uncertainty in his estimates. Describes a method whereby a forecaster can prepare probability distributions of enrollment predictions. The Monte Carlo computer simulation calculates enrollments by the multivariable method,…
