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…

This study in parametric test theory deals with the statistics of reliability estimation when scores on two parts of a test follow a binormal distribution with equal (case 1) or unequal (case 2) expectations. In each case biased maximum-likelihood estimators of reliability are obtained and converted into unbiased estimators. Sampling distributions…

This booklet is one of a series intended to provide explicit instructions for the collection of oceanographic data and samples at sea. The methods and procedures described have been used by the Scripps Institution of Oceanography and found reliable and up-to-date. Instructions are given for taking air samples on board ship to determine the…

Quality assurance is viewed as a means of maintaining desired performance levels during the operational use of a developed instructional program. Presented here is an analysis of the functions and the basic requirements of a quality assurance system. Procedures for implementing the system are described and discussed. The procedures include…

Included in this report on Arizona Indian demographic data are "an evaluation of several recent studies of Indian populations" and "an extensive analysis of methods for obtaining and maintaining accurate data in the future." Recommended methods by which accurate population data for the smaller reservations should be maintained are included in the…
