The purpose of this investigation was to test the efficacy of a study method which was designed to reduce or eliminate verbal learning differences between high and low learning ability Ss. (Authors)

Author discusses the importance of vocalization in the development of basic musicianship. He cites studies demonstrating that vocal teaching strategies, such as singing tonal patterns, aids music reading, memory, and instrumental performance. (SJL)

Average and poor writers were given taped handwriting lessons in one of four combinations of instructional methods: relaxation-suggestion, traditional instruction (Noble's handwriting series), a combination of the two, and relaxation only. The average and poor writers responded differently to the four methods. (SJL)

An approach to supervisory development programs in use at the Fort Wayne State Hospital and Training Center, makes use of video tape and role playing techniques, resulting in a lower rate of turnover and employee grievances, and a measurably higher rate of self-esteem among the participants in the taped interviews.

This study uses a conceptual problem-solving test to investigate the effect of a series of pictorial analogies on the concepts of density, pressure, and atmospheric pressure in Year Eight classrooms. Findings indicate that students taught with the pictorial analogies scored significantly higher than their counterparts. Low achievers were the most…

Empirical research concerning the selection of school administrators was reviewed. The methodology of the review, the methods by which principals are typically selected, and empirical research on the validity of selection techniques are described. Data from 138 studies with managerial and professional samples were analyzed. (TJH)

The logical flaw of using the methods of path analysis and structural equation modeling to make causative conclusions is demonstrated. A proper evaluation of the role of investigation versus experimentation is cited in the work of W. G. Cochran as explicated by D. R. Rubin (1983). (TJH)

Situations for which the researcher should use component analysis versus common factor analysis are discussed. Topics addressed include key algebraic similarities and differences, theoretical and practical issues, the factor indeterminacy issue, latent versus manifest variables, and differences between exploratory and confirmatory analysis…

The empirical performance under null/alternative hypotheses of the likelihood ratio difference test (LRDT); Lagrange Multiplier test (evaluating the impact of model modification with a specific model); and Wald test (using a general model) were compared. The new tests for covariance structure analysis performed as well as did the LRDT. (RLC)

Simulation studies (N=4,000 simulees) examined the effect of misspecification of the latent ability distribution (theta) on the accuracy and efficiency of marginal maximum likelihood (MML) item parameter estimates and on MML statistics to test sufficiency and conditional independence. Results were compared to those of the conditional maximum…

The standard error (SE) of correlations adjusted for selection with commonly used formulas was investigated. The study provides large-sample approximations of SE using the Pearson-Lawley three-variable correction formula, examines the SE under specific conditions, and compares various estimates of SEs under direct and indirect selection. (TJH)

Community participation is central to achieving sustainable natural resource management. A prerequisite to informed participation is that community and stakeholder groups have access to different knowledge sources, are more closely attuned to the different issues and viewpoints, and are sufficiently equipped to understand and maybe resolve complex…

Although researchers studying human speech recognition (HSR) and automatic speech recognition (ASR) share a common interest in how information processing systems (human or machine) recognize spoken language, there is little communication between the two disciplines. We suggest that this lack of communication follows largely from the fact that…

The authors are conducting a three-part study to evaluate current trends in the preservation of digital content, with an emphasis on electronic records. The study emanated from the authors' work on the Preservation Task Force of the International Research on Permanent Authentic Records in Electronic Systems (InterPARES) project. This article…
