Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

This article defines test bias and reviews research methods most aptly applied postpublication to educational and psychological tests. Best methods for estimating bias in criterion-related or predictive validity and determining bias in construct validity across groups are explained. (Author/JDD)

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

A study examined the validity of using questions concerning retirement expectations in large-scale micro surveys. A simple static labor supply model that considered wages, hours worked, and health data was developed for this purpose. Next, the model was implemented using data from the National Longitudinal Survey (NLS) on the Labor Market…

This study explores extent to which postgraduate students are able to learn from holist and serialist learning materials and extent to which such competence is predictable by questionnaires. Results indicate 2 of 26 students scored equally well on holist and serialist competence tests, and such competence is predictable from questionnaires. (MBR)

The Bean and Metzner Nontraditional Undergraduate Student Attrition Model appeared to be a good model to address community college student attrition because it takes into account the environmental variables that colleges must consider to enhance persistence. A study was conducted to determine how well the Bean and Metzner Model fit with community…

Describes an investigation which assessed predictive value of Iowa Test of Educational Development, Science Research Associates Inc.'s Computer Programming Aptitude Battery, and Wolfe Programming Aptitude Test for predicting secondary school students' success in computer science courses, to develop a prediction model, and to estimate mastery…

To determine whether the Posner task, which measures the speed at which information is retrieved from the long term memory, improves prediction of reading comprehension, 121 students from reading and study skills and teacher education courses were administered the Posner task and listening comprehension, reading comprehension, and SAT verbal…

The Johari Window--a model that categorizes degree of self-awareness and openness in communication into (1) information known to self and others (open), (2) information known to self but not to others (hidden), (3) information known to others but not self (blind), and (4) information known neither to self nor to others (unknown)--is a frequently…

This paper illustrates the need for full description and measurement of differences between "experimental" and "control" situations in school program evaluation studies. Two studies were completed at the University of Oregon involving the innovative program--differentiated staffing (DS). The first study, a doctoral investigation, sought to assess…
