This book is designated for an audience of the practitioners of education, especially those located in elementary schools. It is designed to investigate and explain research methods, terms, and concepts so that the reader can narrow down the many ways things are known or said to be known. Included in this book are chapters on the research process…

An audiometric screening survey was conducted on a severely and profoundly mentally retarded population using noise-makers and pure tone audiometry. Of those tested with noise-makers, 83% gave an identifiable response to sound, 7% did not respond, and 10% were considered difficult-to-test. By contrast, 4% passed, 2% failed, and 94% were…

This study examines a common set of equating items for their appropriateness to both American and Canadian populations and, to determine the equations for converting scores from the verbal and mathematical scales of the 1971 form of the Canadian Scholastic Aptitude Test (the future standard continuing scales of the CSAT) to the corresponding…

Reported were results of 17,000 Stanford Academic Achievement Tests administered to students enrolled in primary and secondary educational programs for the hearing impaired. Test results were presented according to student age and three classifications of hearing loss levels. Bar graphs and tables showed subtest patterning trends for the learning…

This speech discusses performance contracting as educational research, notes some evaluation problems, and proposes solutions to these problems. The term performance contracting, according to the report, denotes an administrative rather than an instructional innovation. The author observes that the understanding of instruction and learning derived…

Since the primary purpose of classical testing is to rank order examinees consistently, the absolute value of the true score has been relatively unimportant. However, the major purpose of criterion referenced testing is to estimate the true capabilities of examinees to perform specific tasks. Hence, the problems of true score determination assume…

The New York State Physical Fitness Screening Test, an individual performance-type test composed of four different test items, was developed to provide school personnel with an instrument for use in determining the physical fitness of pupils and to screen pupils who are physically underdeveloped. The original norms for the test were obtained in…

Compared the "hybrid" Test of Understanding in College Economics (TUCE) with the four original TUCE versions and found that the hybrid version is 1) "broader,""thinner," and less technical in terms of content coverage; 2) more reliable with a generally superior item analysis structure; and 3) slightly "easier" for students who have taken economics…

Notes that even with the problems identified in this paper, consistent, positive results are appearing in preliminary reports. Equally important, the data seem to support a number of reasonable notions about the impact of distinctive curricula on students. (Author/AM)

The Trent Attribution Profile provides measures of locus of control and stability which can be further partitioned into individual attribution elements (ability, effort, task difficulty, luck). Reliability and validity data are reported. (Author/JKS)

The article indicates the contradiction that has existed in the scoring and interpretation of test batteries. The multifactor tests of intelligence measure many different human attributes, yet the interpretation of the results of testing with these instruments is based, almost universally, on a single index.

While the constructs of aptitude and achievement, which are defined as genotypic and environmental constructs, are potentially useful in psychological theory and in the development of predictors, the use of these terms for psychological tests is highly misleading. Implications of this position for group differences in aptitude and construct…

Statements made in a previous article of this journal concerning the Rasch latent trait test model are questioned. Methods of estimation, necessary sample sizes, several formuli, and the general usefulness of the Rasch model are discussed. (JKS)

Using the assumption of randomly parallel tests and concepts from generalizability theory, three signal/noise ratios for domain-referenced tests are developed, discussed, and compared. The three ratios have the same noise but different signals depending upon the kind of decision to be made as a result of measurement. (Author/JKS)

In group work little attention is paid to the environmental influences upon members. The EAI-G provides a tool for gauging the campus impact upon group participants. (Author)
