This study reviews the literature on the social and behavioral characteristics of only children in China. Of 16 studies that reported differences in the characteristics of only and non-only children, only 2 indicated that only children exhibited more socially desirable behaviors than did non-only children. The remaining studies reported that,…

The problem of determining optimal test lengths with fixed total testing time has proved to be a difficult one for criterion-referenced test developers. An algorithm is needed which can be used by test developers to allocate available testing time to maximize the validity of their total criterion-referenced tests or testing programs. To be…

Educators designing procedures for identifying students as learning disabled are faced with serious technical difficulties. A student with a learning disability is one who "has a severe discrepancey between achievement and intellectual ability" in one or more designated areas. The methods of quantifying achievement, intellectual ability,…

Previous research has studied the effects of different methods of item option weighting on the reliability and concurrent and predictive validity of achievement tests. Increases in reliability are generally found, but with mixed results for validity. Several methods of producing option weights, (i.e., Guttman internal and external weights and…

The Emory Word Analysis Skill Inventory (EWASI) was developed to diagnose individual word analysis skill abnormalities exhibited by students enrolled in private tutoring in the Emory University (Georgia) Reading Center. In the EWASI, 13 subscales contain three broad categories--consonants, vowels, and word structure. The goal, however, is to…

Since middle schools vary in their degree of implementation of middle school practices, this research was designed to compare the job satisfaction of middle school teachers with the degree of implementation of these practices. Six teachers from each of Colorado's 50 schools with the name "middle school" were randomly selected to serve as…

Monte Carlo simulation procedures were used to study the psychometric characteristics of two two-stage adaptive tests and a conventional "peaked" ability test. Results showed that scores yielded by both two-stage tests better reflected the normal distribution of underlying ability. Ability estimates yielded by one of the two stage tests…

The Kuder Richardson-20 Formula is shown to be a special case, where each examinee is given sufficient time to answer each item, of a more general formula where each examinee may not be allowed the necessary time. The formula is extended to allow two scores, knowledge and speed, to be extracted from each examinees test score. Using a sample of 82…

This explanatory booklet and the materials that accompany it have two major purposes. The first purpose is to provide local school officials with information regaing the performance on basic skills achievement of each student who took the 1971-72 Michigan Educational Assessment Battery. The second purpose is to provide local officials with…

The purpose of this research was to conduct a preliminary analysis of a new instrument, the Classroom Environment Index (CEI), designed to measure the psychological environment (press) of the classroom. The structure was essentially the same as other Syracuse indexes, containing 30 scales of 10 items each. Three forms of the instrument were…

Scores of high school students responding to the same biology cognitive preference test using both normative and ipsative procedures were compared. All subtests, whether ipsative or normative, had high alpha Cronbach coefficients. A number of similarities were found in the mean scores obtained by the two procedures, as well as moderate positive…

The proposed theory provides a basis for both measuring and correcting rater stringency error in some grossly incomplete rating data matrices. The theoretical model fits ratings made by faculty and resident physicians of student clinical performance in each of three junior year medical student cohorts better than alternative models.

Discusses aspects of the Family Narrative Consortium's multisite, multidisciplinary collaboration to study the effect of social context on family narratives. Considers the value of the study for developing a coding system for narratives that yields comparable results across research sites. Examines the measures, epistemological issues,…

A study of methods used to ensure validity and reliability in classroom assessments surveyed 625 elementary and secondary teachers in Ohio. Results indicate teachers spent little time conducting statistical analyses of their student evaluation data, and many techniques used were poor and inadequate. Additional professional development and improved…

Efficient methods of using the Statistical Package for the Social Sciences (SPSS) to analyze National Assessment of Educational Progress (NAEP) data files are discussed. One error in the NAEP SPSS file is discussed, and another error (which may be system-dependent) is mentioned. In addition, purely mathematical methods are used to address the…
