The different components of air monitoring networks, the status of air monitoring in the United States, and the services and activities of the three major American network builders are detailed. International air monitoring networks and alert systems are identified, with emphasis on the Dutch air monitoring network. (BT)

This study comparing momentary time sampling against the real time obtained with handheld computers confirmed laboratory findings that short-elementary time sampling estimates percentage time accurately for a wide range of behavior frequencies and durations, and suggested that observers using momentary time sampling in a natural setting are able…

Presents an activity on the simplification of penguin counting by employing the basic ideas and principles of sampling to teach students to understand and recognize its role in statistical claims. Emphasizes estimation, data analysis and interpretation, and central limit theorem. Includes a list of items for classroom discussion. (ASK)

Norm-referenced tests yield information regarding a student's performance in comparison to a norm or average of performance by similar students. Norms are statistics that describe the test performance of a well-defined population. The process of constructing norms, called norming, is explored briefly in this paper. Some of the most widely reported…

Article attempted to answer the question: would a nonverbal method of communicating test instructions influence scores achieved by young children on the Figural Forms of the TTCT. (Author/RK)

This booklet is intended to serve as a step-by-step layman's guide to conducting a community survey, tabulating the findings of the survey, and presenting a final report of the survey findings. It is written in simple nontechnical language and contains numerous examples of various survey forms and procedures. Among the major topics discussed are:…

The fifth of a series of brief reports on the study of mental retardation in a Canadian province covers a period of approximately one year (September, 1969, through November, 1970). The period under review is primarily one of data gathering with the emphasis on the adequacy of the sampling procedure, follow up of incomplete interviews, and tapping…

The objectives of this study were to: (1) develop a rationale and structure for quantifying individual demands of people for vocational education, (2) demonstrate a method of quantifying these demands, and (3) develop a set of guidelines for administratores at State and local levels for determining individual demand for vocational education.…

Some of the requirements and consequences of rigorous and valid educational evaluation research are explored in terms of problems in achieving two types of external validity, population and ecological. The former refers to the generalizability of inferences to subjects not included in a study, while the latter is concerned with the…

This report summarizes tasks undertaken to assess the feasibility of a longitudinal analysis of elementary and secondary schools. The initial objective was to see if it was technically possible to analyze overlap samples of schools from the Schools and Staffing Survey (SASS) to produce substantive findings. Over the course of the project various…

Procedures to be applicable in situations in which large numbers of individuals are tested or in situations where multiple measures are taken. (Author/CB)

Presented at the 66th Annual Convention of the National Catholic Educational Association, Detroit, Michigan, April 7-10, 1969.

Investigators are urged to plan factor analytic studies prior to collecting the data, to formulate a hypothesized factor structure, to develop several relatively pure measures of each factor expected, and to select an appropriate sample of at least 200 cases. Continuous variables should be used rather than dichotomous variables. (Author)

A major problem in social science research is that of successfully carrying out the random assignment of persons to experimental and control groups. In this study a computer-based random assignment procedure operated successfully on a weekly basis for 17 consecutive weeks in a program serving over 360 ex-offenders. (CTM)

More and more researchers, evaluators, and policy makers are recognizing that in order to best understand the factors precipitating, supporting, and prohibiting intimate violence against women, we must often gather information directly from battered women themselves. Such data collection, however, is not without its risks to the women involved in…
