"Gedankensimulation" is a term adapted from Einstein's "thought experiments" to indicate mentally created simulations that can help conceptualize ideas. Presents seven examples of simulations that can be utilized to solve problems or illustrate concepts in probability and statistics. Problem contexts include games of chance,…

Presents a series of activities using data collection and interpretation techniques designed for levels 1-8, 1-5, 3-6, and 4-8 that integrate mathematics and social studies through the common theme of television viewing. Includes an activity sheet for parents to use with their children, three class-activity sheets, and a data sheet. (MDH)

Examines a frequently discussed indicator of child well-being, the high school dropout rate. School-linked services will be successful only to the extent children are in school. First in a feature series ("Child Indicators") that analyzes implications and limitations of key statistical indicators of the well-being of children. (SLD)

Discussion of allocation of library acquisitions budgets, especially for monographs, focuses on the proportional use statistic (i.e., a value that compares circulation and holdings in a subject area). Topics addressed include economics; benefits that libraries provide; use of the collection by patrons; computers as aids to resource allocation;…

Proposes an empirico-statistical model to differentiate dependent and independent historical texts. Formulates a regard for information principle and an amplitude correlation principle. Experimentally examines and validates the model and both principles using specific historical texts. Includes tables and graphs. Appends further discussion of the…

Presents a series of four steps used in data analysis processes that help students investigate and interpret real world situations. Gives activities that employ computer software to create representative graphs of the data in the analysis process. (MDH)

Six existing statistical procedures (models) for indirectly assessing the prevalence of need for alcohol, drug abuse, and mental health services across subareas of a state are described and critiqued in terms of epidemiological and statistical characteristics. Specific advantages and disadvantages are listed for each model. (SLD)

Whether indexes of cognitive processes that affect adults are related to sentence reading times and recall was studied for 49 fifth grade and 73 seventh grade good and poor readers. Younger children differed from older children in that greater numbers of causal relations were associated with better sentence recall. (SLD)

Compares public library use surveys conducted in 1948 by the American Library Association and in 1991 by the National Center for Education Statistics. Results indicate that public library use by both adults and children has risen dramatically, but library use by minorities and low income adults has changed very little. (KRN)

Three classes of variables were used to predict three indices of intervention outcomes for children with handicaps and developmental delays. Results suggest the important role of nonprogram variables in determining outcomes in programs that train parents to teach preacademic, communication, social, self-help, and motor development skills.…

Presents results of a study of neighborhood effects on educational attainment in Scotland. Reports a significant negative association between deprivation in the home neighborhood and educational attainment. Concludes that policies to alleviate educational disadvantage must focus on social deprivation in the society at large and not just on…

Use of the bootstrap resampling technique (BRT) is assessed in its application to resampling analysis associated with measurement of payment allocation errors by federally funded Family Assistance Programs. The BRT is applied to a food stamp quality control database in Oregon. This analysis highlights the outlier-sensitivity of the…

Presents activities in which students develop and analyze scatterplots on graphing calculators to model corn growth, decay, a box of maximum volume, and weather prediction. Provides reproducible worksheets. (MDH)

Reports on characteristics significantly related to teacher retention in a large urban school district using a Cox regression model to model teacher turnover for a sample of 2,327 white, black, and Hispanic-American first-year teachers. Sex, ethnicity, education, and certification route are significantly related to teacher retention. (SLD)

This study tested assumptions about self-sufficiency of academic library collections and the paradigm shift to providing access to information stored elsewhere. Inter-library borrowing statistics of Australian libraries were correlated with collection size. The study concluded that collection self-sufficiency is a fallacy and that the information…
