We present an expository account of the development of the theory of binary quadratic forms. Beginning with the formulation and proof of the Two-Square Theorem, we show how the study of forms of the type x[squared] + ny[squared] led to the discovery of the Quadratic Reciprocity Law, and how this theorem, along with the concept of reduction relates…

The Jordanian General Secondary Education Certificate Examination is an achievement test constructed, administered, scored, and reported by the ministry of Education. The examination is discussed in terms of history, philosophy, objectives, structure and operation, use of data, predictive validity, and side effects. (LMO)

Links the theory of washback with the broader concept of impact in educational measurement and to the recent debate on construct validity associated with Messick. Notes that for many years it was asserted that language tests negatively impacted teaching and learning, an impact known as washback. (25 references) (Author/CK)

We describe a simple classroom activity that demonstrated the process of assessing predictive validity. We assessed changes in student understanding of the process, confidence in psychological testing, and enjoyment in participating in the exercise. Students who completed the activity performed better on a test question about validity and reported…

Although unreliable and not predictive of medical school performance, the admission interview continues to be used extensively to collect noncognitive data about medical school applicants. A procedure is suggested for assuring that a group of interviewers assigned to an applicant does not unfairly help or hinder the candidate's ratings. At least 3…

Today's students experience a great deal of pressure to succeed in school. Since predictors of academic performance are widely used to assess student capabilities, the relationship between one such test, the California Psychological Inventory (CPI), and academic success are examined in this paper. The focus here is on the non-cognitive variables…

While Scholastic Assessment Test (SAT) and American College Testing Program (ACT) scores are viewed as reliable, and colleges and universities continue to use them, they are often misunderstood and misused. They are reliable for predicting freshman grades only when comparisons are made within one racial group. They also do not account for student…

Reviews the eye-movement paradigm and refers to recent experiments applying the paradigm to issues of spoken word recognition (e.g., lexical competitor effects), syntactic processing, reference resolution, focus, as well as issues in cross-modality integration that are central to evaluating the modularity hypothesis. (Seven references) (Author/CK)

Distinguishes two types of materials evaluation: a predictive evaluation designed to make a decision regarding what materials to use, and a retrospective evaluation to examine materials already used. Describes a procedure for conducting task evaluations, suggesting that they constitute a kind of action research that can contribute to reflective…

The majority of depressive symptoms, prevalent among adults (without a history of a depressive disorder) entering alcohol treatment, usually abate within 2 to 3 weeks of abstinence without specific depression-focussed intervention, but some hospitalized alcoholics experience significant depressive symptoms despite sustained abstinence. Such…

Some early childhood variables are examined to evaluate their predictive validity. The selection of children needing early childhood Title I services is complicated by the lack of criteria for defining who is educationally disadvantaged and the special problems of early childhood testing and measurement. The study used re-analysis of longitudinal…

The Computer Aptitude, Literacy, and Interest Profile (CALIP) is a standardized test battery with six subtests designed to assess computer-related abilities of individuals between 12 and 60 years old. The CALIP was developed to assess computer-related aptitudes of younger or inexperienced populations, including talented minority persons and…

Where human beings are concerned and complex behavior is involved, prediction of future performance is no simple matter. Scientifically developed, systematically standardized and carefully validated tests have emerged as the most reliable tools in predictive efficacy. If opponents of standardized testing win, society will lose. (Author/CM)

Provides an overview of the development of the Brazelton Neonatal Behavioral Assessment Scale (NBAS), the nature of the instrument and conditions for its proper administration, and issues underlying the use of the NBAS in research (e.g., reliability). The first in a series of articles in a single monograph assessing the NBAS. (BH)

Probes validity issues of computer-assisted strategy assessment in second language acquisition research. Reviews metacognitive and cognitive strategies, discussing trait-oriented and interactionist approaches in the concept of strategy, and examining validity by focusing on "advance preparation" and "resourcing" examples of…
