The hypothesis that alpha brain wave biofeedback training elevates mood was tested. Three groups of eight naive subjects each were formed: Group 1 underwent training, Group 2 kept the alpha feedback signal off, and Group 3 named titles of tunes. The hypothesis was not supported. (Author)

Contrasts lay and "professional" metalinguistic knowledge from the viewpoint that linguistic issues concern all speakers of language. The article maintains that linguists firmly believe in a major difference between lay and theoretical metadiscursive remarks because linguists persist in believing in the objectivity of linguistic facts.…

This study tested three versions of the "abuse-to-abuser" hypothesis by comparing men with personal histories of sexual abuse and men without sexual abuse histories. There was a statistically non-significant trend for assaulted offenders to be more likely as adults to commit genital assaults on children. Implications for the abuse-to-abuser…

Explores the possibility that the first language and second language mental lexicon may be structurally similar, with depth of individual word knowledge determining a given word's degree of integration into the mental lexicon. Proposes a model for the process by which words are integrated into the mental lexicon and challenges the belief that a…

A general process for faculty to use in comparing the relative efficacy of college outcomes assessment instruments for gauging student progress toward goals is outlined. Analysis of two standardized general education exams, the American College Testing College Outcome Measures Project and the Educational Testing Service Academic Profile,…

Five methods for testing the hypothesis of independence between two sets of variates were compared through simulation. Results indicate that two new methods, based on robust measures reflecting the linear association between two random variables, provide reasonably accurate control over Type I errors. Drawbacks to rank-based methods are discussed.…

Contrasts "mental models" used by automated scoring for the simulation division of the computerized Architect Registration Examination with those used by experienced human graders for 3,613 candidate solutions. Discusses differences in the models used and the potential of automated scoring to enhance the validity evidence of scores. (SLD)

Dental hygiene students (n=15) took a first examination on computer then paper; 15 others took the paper test first. Computer test scores were higher than paper for the first exam. Student acceptance of the computer format was mixed. Computer exams reduced scoring and grade reporting time. (SK)

Explores whether the functional element effect (Muysken, 1997), often observed in production, is replicated in on-line comprehension results. Compared results of published frequency counts involving Spanish-English code switches with comprehension-timed experimental results. (Author/VWL)

Discussion of adapting traditional paper and pencil tests to electronic formats focuses on a study of undergraduates that examined the equivalence between computer-based and traditional tests when the computer testing provided opportunities comparable to paper testing conditions. Results showed no difference between scores from the two test types.…

The efficacy of two types of therapy conducted exclusively over the telephone was studied. Clients (N = 55) were recruited from a pool of callers to a suicide hotline and were randomly assigned to a waiting list control (WC) or Solution Focused Brief Therapy (SFBT) or Common Factors Therapy (CFT). It was hypothesized that improvements would be…

Instructing people to forget a list of items often leads to better recall of subsequently studied lists (known as the benefits of directed forgetting). The authors have proposed that changes in study strategy are a central cause of the benefits (L. Sahakyan & P. F. Delaney, 2003). The authors address 2 results from the literature that are…

The Second International Conference on Educational Data Mining (EDM2009) was held at the University of Cordoba, Spain, on July 1-3, 2009. EDM brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large data sets to answer educational research questions. The increase in instrumented…

This study is a comparison of 2 versions of an Internet-based tutorial that teaches the behavior-analysis concept of positive reinforcement. A fixed-item group of students studied a version of the tutorial that included 14 interactive examples and nonexamples of the concept. A response-sensitive group of students studied a different version of the…

This paper describes the development of the CAOS test, designed to measure students' conceptual understanding of important statistical ideas, across three years of revision and testing, content validation, and reliability analysis. Results are reported from a large scale class testing and item responses are compared from pretest to posttest in…
