In undergraduate research settings, students are likely to encounter anomalous data, that is, data that do not meet their expectations. Most of the research that directly or indirectly captures the role of anomalous data in research settings uses post-hoc reflective interviews or surveys. These data collection approaches focus on recall of past…

Research on spatial navigation is essential to understanding how mobile species adapt to their environments. Such research increasingly uses virtual environments (VEs) because, although VE has drawbacks, it allows for standardization of procedures, precision in measuring behaviors, ease in introducing variation, and cross-investigator…

Daniel Koretz is the Henry Lee Shattuck Professor of Education at the Harvard Graduate School of Education. His research focuses on educational assessment and policy, particularly the effects of high-stakes testing on educational practice and the validity of score gains. He is the author of "Measuring Up: What Educational Testing Really Tells…

Areal data have been used to good effect in a wide range of sociological research. One of the most persistent problems associated with this type of data, however, is the need to combine data sets with incongruous boundaries. To help address this problem, we introduce a new method for identifying common geographies. We show that identifying common…

The use of standardised tests as a central tool in education policy has in recent decades become a common feature of many national education systems. In 2002 the Israeli Ministry of Education introduced new mandatory state tests for primary and middle schools. The article describes the adoption of these low-stakes tests and assesses their impact…

A total of 19 graduate students enrolled in a graduate course conducted 6 consecutive administrations of the Wechsler Intelligence Scale for Children, 4th edition (WISC-IV, Canadian version). Test protocols were examined to obtain data describing the frequency of examiner errors, including administration and scoring errors. Results identified 511…

In this article, we introduce a person-fit statistic called the hierarchy consistency index (HCI) to help detect misfitting item response vectors for tests developed and analyzed based on a cognitive model. The HCI ranges from -1.0 to 1.0, with values close to -1.0 indicating that students respond unexpectedly or differently from the responses…

The paper states that quantification is neither ethical nor unethical, but is ethically neutral. It is the behavior or intent of the human being that is clearly a matter of ethical concern. Like numerology and the sects of inumerates and qualitatives, there is not so much an unethical practice that is supported as there is a lack of vision and…

Correction for guessing does not fulfill its intended function when test takers who have nothing to gain from scoring will respond randomly when they could have answered correctly had they tried. Raw scores underestimate abilities. If random guessing is more prevalent in the control group, correction for guessing inflates treatment effects.…

Reviews the alternative meanings of the term "poverty" implied in the various ways in which it has been measured. Conclusion is drawn that it is not safe to assume different indicators of poverty are more or less equivalent. (Author/AM)

The state of research on intelligence is reviewed in an editorial. The author notes conceptual, measurement, and data analysis problems. Suggestions as to how research on intelligence can be improved are provided. (RD)

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…

Demonstrates the effect of race of test administrator on the responses of experimental groups of white undergraduate subjects on a comprehensive battery of attitudinal measures. (JM)

In discussing the problems of evaluating Canadian bilingual immersion programs, six related aspects are separately considered: (1) the research design, (2) the students tested, (3) the nature of the tests used, (4) the methods of analysis employed, and (5) the interpretation of findings.
