This paper presents a study of behavioural variables implied in the working dynamics of student groups undertaking their first project. The study was carried out in two phases. During the first phase, the participants answered a survey of open questions regarding their own behaviour and that of their teammates, questions related to: the quality of…

In recent years, considerable attention has been paid to the alleged changes in the ways the so-called "digital generation" communicates and learns. Most of the commentary has been based on anecdotes, observations and opinions. The lack of empirical evidence in this matter suggests that it may be time to begin the process of gathering…

Empirical research on anger and hostility has pervaded the academic literature for more than 50 years. Accurate measurement of anger/hostility and subsequent interpretation of results requires that the instruments yield strong psychometric properties. For consistent measurement, reliability estimates must be calculated with each administration,…

Rosenthal and Rubin introduced a general effect size index, r[subscript equivalent], for use in meta-analyses of two-group experiments; it employs p values from reports of the original studies to determine an equivalent t test and the corresponding point-biserial correlation coefficient. The present investigation used Monte Carlo-simulated…

The Diagnostic Teacher Assessment in Mathematics and Science (DTAMS) was developed to measure the content knowledge and pedagogical content knowledge of middle-school teachers. Its reliability and validity were initially established by reviewing national standards for content and use of expert question writing teams and reviewers. DTAMS was…

Antisocial personality disorder (ASPD) is associated with suicide, violence, and risk-taking behavior and can slow response to first-line treatment for Axis I disorders. ASPD may be assessed infrequently because few efficient diagnostic tools are available. This study evaluated 2 promising self-report measures for assessing ASPD--the ASPD scale of…

Purpose: The paper's aims is to explore the relationship between having a complete strategic focus and the extent of the internationalisation of university business schools and the level of desire for the future internationalisation and to further validate the model of internationalisation. Design/methodology/approach: Data were collected for…

The original grounded theory was derived from a sample of junior and senior science and engineering majors. The current study tested the original grounded theory with a new set of juniors and seniors who were, in contrast to the original sample, primarily studying the liberal arts. In this qualitative analysis, the authors sought to determine if…

This article discusses the evidence for intervention validity of Functional Behavior Assessment (FBA) in designing support for students with intensive behavioral needs. Since its inclusion into the Individuals With Disabilities Education Act nearly a decade ago, FBA has been the subject of significant research investigating its use and…

This article focuses on the accuracy of satellite data, which may then be used in wave power applications. The satellite data are compared to data from wave buoys, which are currently considered to be the most accurate of the devices available for measuring wave characteristics. This article presents an analysis of satellite- (Topex/Poseidon) and…

Griffiths, Christian, and Kalish (this issue) present an iterative-learning paradigm applying a Bayesian model to understand inductive biases in categorization. The authors argue that the paradigm is useful as an exploratory tool to understand inductive biases in situations where little is known about the task. It is argued that a theory developed…

Congruency effects are typically smaller after incongruent than after congruent trials. One explanation is in terms of higher levels of cognitive control after detection of conflict (conflict adaptation; e.g., M. M. Botvinick, T. S. Braver, D. M. Barch, C. S. Carter, & J. D. Cohen, 2001). An alternative explanation for these results is based on…

The current study examined the validation and alignment of the PASA-Science by determining whether the alternate science assessment anchors linked to the regular education science anchors; whether the PASA-Science assessment items are science; whether the PASA-Science assessment items linked to the alternate science eligible content, and what…

In 1998, the California legislature passed Senate Bill SB 2042 which replaced the previous teacher certification legislation. The new law required that all elementary and secondary teacher certification programs in the State of California align their programs with new teaching standards. These standards included Teacher Performance Expectations…

The Community College Student Report (CCSR) is a widely-used survey instrument. This article examines the reliability and validity of the instrument to assess its usefulness in institutional research and practice. Confirmatory factor analyses demonstrate that factor analytic models adequately represent underlying constructs. Confirmatory factor…
