Standardized testing is an external control mechanism for K-12 public schools. Principals, nested between internal and external influences, must manage the tension created by testing's roles as both an internal improvement tool and as an external control mechanism. Five competing narratives, each shaped by author academic background, significantly…

This paper demonstrates the variety of positive-skew phenomena and discusses their theoretical, research, and practical implications in education. (PN)

Reviews the role of statistical hypothesis testing in research, discusses the problems with multiple t tests, indicates when they are a problem, and suggests a compromise solution. (one reference) (JL)

This paper reviews research on symbolic play gaps between children with and without language impairment (LI), arguing that these gaps should not be interpreted as demonstrative of marked deficits in general representational or specific symbolic play competence of children with LI. Frequent encroachment of language into testing procedures is cited…

Considers three issues related to the conduct of research into reading problems of the elderly: (1) the lack of federal funding of literacy research concerning the elderly, (2) differences between conducting research with school-aged populations and with the elderly, and (3) problems encountered in testing elderly individuals. (GT)

There are many opportunities for research on how self-assessment affects behavior, especially external and internal mobility. Problems often occur in choice of ability dimensions and selection context. A firm theoretical base is necessary. (JAC)

The purpose of this paper is to discuss ways in which developmental psychology suffers from the lack of an appropriate technology of measurement and statistical analysis. The paper begins by noting that developmental psychology is the study of change; that individuals develop through a succession of "stages" which are separated by…

Factor analysis is of limited value in investigating the influence of students' implicit theories about teachers' behaviors on student evaluations of teachers. (MH)

Research on assessing the cultural fairness of individual test items is reviewed, with emphasis on Birnbaum's three-parameter logistic model. As defined in this review, differential item characteristics are exhibited when examinees from one group have a lower probability of answering correctly than do examinees of equal ability from another group.…

The many studies comparing good and poor readers have yielded few conclusive findings as a result of a number of problems. The first set of problems has to do with the choice of tests or tasks. There are many differences in the cognitive demands of reading and listening tasks children encounter in school. In listening, prosodic cues facilitate…

Practices identified by experts as critical variables in eliciting writing samples were checked against 12 randomly selected studies using holistic ratings to derive descriptions of inferential statistical results for described samples. The studies often lacked precise information about these variables, limiting understanding of writing evaluation…

This review of the literature addresses scientific and methodological concerns of research with children from various racial and ethnic backgrounds in the United States. It first identifies three major demographic trends: (1) the increasingly multiethnic and multilingual nature of American society; (2) the increasing number of children in poverty;…
