Analysis of a sample of 100 pupil scripts from a British Assessment of Performance Unit survey suggests that ability to read and interpret graphical data should not be seen as an independent process skill. Instead, hidden cognitive demands of assessment items require integrated understanding based on a sophisticated procedural model. (SK)

Discusses two tools necessary for the successful practice of human performance technology: gathering data and interpreting data. The focus is on what data to gather, how to gather it, and how to interpret the data. (Author/JKP)

Presents conceptual and analytical framework for addressing change in public opinion. Explores the possibility that public opinion changes because publics change. Concludes that, by modifying existing component-difference research methods, the proximate sources of societal change can be separated using repeated survey data. Provides an example by…

Meta-analysis is proposed as an effective alternative to conventional narrative review for extracting trends from research findings. This type of analysis is explained, advantages over more traditional review techniques are discussed, basic procedures and limitations are outlined, and potential applications in dental education and clinical…

Students with severe/profound mental retardation performed functional tasks under training or probe conditions. Analysis of nine students' records indicated that students do not react to probe conditions as if they were extinction conditions; training data do not consistently reflect performance under probe conditions; and data collected under…

Psacharopoulos has found a declining rate-of-return to education pattern across levels of per capita income, using international data. A reexamination of Psacharopoulos's cross-country data refutes his declining rate-of-return hypothesis and points to diversity of cross-country experience as a possibly significant factor in interpreting the data.…

Curriculum scholarship involves "reading for meaning" perhaps more than any other professional competence except observing. Deconstruction ventilates this activity by asking what reading for meaning means, exposing some habits normally governing it, and proposing a way of reading that is radically open to diversity. (MLH)

Data from the experimental functional analysis of challenging behaviors of 27 individuals with mental retardation were analyzed to assess agreement among three forms of interpretation. Results found that the methods of interpreting function from experimental assessment can give different results and that test-retest reliability of the experimental…

Statistical significance reporting and use in educational and psychological research is reviewed. An assessment of the use of statistical significance in articles published in MECD from 1990-1996 is presented. The elements of statistical significance (including sample size, effect size, and power), interpretation of results, common erroneous…

Responds to a commentary on a 1996 paper that surveyed pronominal systems with first person n and second person m and showed that the n:m system is insufficient to prove genetic relatedness among languages exhibiting it, suggesting that the commentary was based on misunderstandings. The response addresses the commentary's discussion of study…

Describes a four-week rotation at the State University of New York Health Science Center in Brooklyn in which medical residents are taught community health assessment using a problem-based format. They use demographic and health data to create rates they believe will help to illuminate the health status and health issues of their assigned…

Reviews the rationale for and implications of case study research in therapeutic recreation, examining: what can be learned from studying a single case; issues of validity and reliability; ethical conduct of research; and the practice of case study research (case protocol, case selection, collecting data, analyzing and interpreting data, and…

Reporting how many people scored at a certain level or how many people passed a cut score is not the same thing as reporting the scores themselves. The newest (indefensible) cliche, derived from international test-score comparisons, says American kids get dumber the longer they stay in school. (MLH)

Reports on a study designed to develop and validate a framework for characterizing middle school students' thinking across four processes: describing data, organizing and reducing data, representing data, and analyzing and interpreting data. Results indicate that students progress through four levels of thinking within each statistical process.…

Examines the theoretical basis for data mining, one of the essential knowledge management processes, and uses a case study to describe its application and impact. (EV)
