Time sampled observations of the cooperative behavior of two samples of 31 preschool children were analyzed for stability (that is, short term reliability of behavior) over a 2-month period using Cronbach's generalizability coefficient. Observations were made during free play periods on nursery school settings. The observation schedule required…

ACCURATE ASSESSMENT OF COMMUNITY OPINION AND REACTION DEPENDS UPON ADEQUATE SAMPLING TECHNIQUES. VOTER REGISTRATION LISTS PROVIDE ONE SOURCE FROM WHICH TO DRAW SAMPLES. RESEARCHERS MUST CONSIDER THE COSTS OF LARGE SAMPLES IN RELATION TO TWO QUESTIONS--(1) THE CLOSENESS WITH WHICH THE TOTAL POPULATION IS TO BE MATCHED BY THE SAMPLE, AND (2) THE…

This brief guide to interview training in survey research is designed for persons without previous training or experience in interviewing. Basic techniques of interviewing are presented in such a manner as to facilitate the training of persons with varying educational and socioeconomic backgrounds. Topics include: the interviewer's role in the…

This pamphlet describes the exciting potential of item banking--a new approach to testing which combines both comparability of scores with flexibility of test format. Item banks are collections of items where the characteristics of each item is known and these characteristics can be summated to described a test made from such items. The principle…

This paper briefly discusses the use of item sampling for student evaluation in a summative evaluation context. Its proposition is that item sampling is a means of achieving better and broader student evaluation because it leaves room for individualized evaluation. Item sampling can be implemented properly by associating it to the concept of item…

Two of these three pamphlets describe methods of teaching young elementary school children the principles of sampling. Tiles of five colors are added to a tub and children sample these randomly; using the tiles as units for a graph, they draw a representation of the population. Pooling results leads to a more reliable sample. Practice is given in…

Comprehensive Achievement Monitoring (CAM), a new evaluation method, systematically and comprehensively measures student achievement. The unique characteristics of this model are described in detail, as are those of two more familiar models, classroom testing, and curriculum program evaluation. The amount and quality of information available from…

Reported are the results of a study which investigated the possible utilization of item sampling techniques with Thurstone's Case V paired comparison method. The first objective involved the study of the scale and rank values of the stimuli and the frequency distribution of the responses. A paired comparison instrument consisting of mathematical…

Reported are sampling methods that may be followed when performing stream studies. Sources of error and methods of their minimization are discussed. Because there is much variation within and between streams it is not possible to provide detailed definitive methods but alternatives are discussed. The selection of sampling sites and sampling…

The task of administrative decision makers at diverse and complex institutions has been made more difficult with student confrontations, and there is an expressed need for improved tools to assess student attitudes and characteristics. The Campus Environment Scale (CES), a data-gathering tool, contains 150 statements that deal comprehensively with…

The uses of simulation as a technique for instruction and research have been expanding over the past ten years. As an aid to educational practitioners, the sampling procedures associated with trivariate normal populations are described along with a description of an APL/1500 computer program for this level of multivariate sampling in educational…

This instrument was developed to assist educational leaders in the collection of data relating to the attitudes of their publics on vital social and educational concerns. It classifies the concerns under: social problems, school program, teachers and instruction, administration, students, and index of attitude toward change. It provides for…

Specific limitations of past research in teacher verbal questioning behavior are presented in this article for the purpose of providing recommendations for future research activities. Analyses are made by reviewing related literature. Limitation factors are identified as resulting from variations in the following aspects: teacher characteristics,…

This report presents the technical details of the sample design used for the day care survey conducted by Westat Research, Inc. under subcontract to Westinghouse Learning Corporation. It follows the recommendations of the preliminary report on sampling design (available as ED 051 880) submitted on August 15, 1970. That report presented the merits…

Gas flow patterns at a sampling nozzle are described in this presentation for the 12th Conference on Methods in Air Pollution and Industrial Hygiene Studies, University of Southern California, April, 1971. Three situations for sampling velocity are illustrated and analyzed, where the flow upstream of a sampling probe is: (1) equal to free stream…
