This study attempted to place children's language in its wider setting and considered the meanings the child can express in connection with the orms in which he expresses them. (Author/RK)

Laboratories using animals were evaluated for their contribution to learning processes of students in introductory psychology courses. (RK)

Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…

This study is a follow-up of an unpublished dissertation study completed in 1964 focusing on the moral attitudes that adolescents develop through interaction with the adult community as well as their peer groups. (Author/RK)

This cross-national/cross-cultural study attempted to determine whether the development of the concept of space is universally invariant in sequence and rate, and whether the capability to deal with the world through two-dimensional reconstructions is innate or affected by experience in different cultures.

One of a series of reports on the International Project for the Evaluation of Educational Achievement (in Mathematics).

Two types of statistical analyses of rating scale data are discussed. An example, with its accompanying mathematical calculations for each type, is presented; and the advantages and disadvantages of each method are compared. It is judged that the little-known and seldom-used Kolmogorov-Smirnov one-sample test should be reexamined because of its…

A method of investigating for possible bias in test items is proposed that uses analysis of variance for item data based on groups that have been selected to have identical test score distributions. The item data used are arcsin transformations of item difficulties. The methodological procedure has the following advantages: (1) The arcsin…

The implications of data from a review of ten years of the American Educational Research Journal (AERJ) indicating that random sampling is rare and that there is increased use of quasi-experimental designs lacking in random assignment are considered. It is suggested that tests of significance could be abandoned or at least placed in a subsidiary…

Three questions are discussed: (1) what approach will be taken to gain and maintain access to school districts and schools to administer assessment instruments? (2) what procedures should be employed in the difficult and complex task of gaining access to nonstudents (age 17)? and (3) what problems are likely to be encountered in doing this? Access…

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…
