Discusses a new technique for training fluid control technicians. Technical Education is a bimonthly supplement to Industrial Arts and Vocational Education. (Editor/GB)

Researchers concerned with the issue of children's play are urged to read the book "Children's Play: Current Theory and Research" edited by D. J. Pepler and K. H. Rubin which provides an up-to-date review of the conceptual, methodological and developmental issues related to children's play. (MP)

Argues that the key distinction of a situated approach to studying intelligent behavior is not the method used but the focus of the investigation, specifically the unit of analysis. Discusses contemporary approaches to assessment, collaborative problem solving as an assessment context, situated assessment, intentional dynamics, and interaction as…

Discusses the implications for scholarly research of the military action taken by the Chinese government during the recent student protests. Points out practical problems as well as moral issues concerning the resumption of normal scholarly activities in China. Explains the possible effects of China becoming a more closed society. (KO)

Employed triangulation strategy for assessing family interaction, involving family members, therapist, and coders independently viewing videotapes. Found weak agreement between paired assessments within family triad, and within therapist-coder dyad. Findings suggest that methodological and/or scaling strategies designed to maximize agreement may…

In this pilot study, 14 adolescents kept diaries for 6 consecutive weeks during their pregnancies. Diary entries were analyzed for affective tone, emotional lability, and contextuality. Findings question psychometric properties of data gathered using one time, self-report measures with pregnant adolescents because of their fluctuating mood states.…

Teachers can help students "find" problems by brainstorming potential research ideas connected to interests they already have. Students of all ages can do descriptive, historical, experimental, correlational, and developmental research. Case, field, causal, and comparative research might be more successful with older students. Conducting real…

Through numerical investigations, this paper studies examples of the forced Duffing type spring equation with [epsilon] negative. By performing trial-and-error numerical experiments, the existence is demonstrated of stability boundaries in the phase plane indicating initial conditions yielding bounded solutions. Subharmonic boundaries are…

Geographical, economic, social and cultural barriers to accessing services in rural areas are widely reported. Less widely discussed are dilemmas posed by individual and community reluctance to address sensitive health issues. This article, focusing on the highly sensitive area of mental health, and employing a participatory action approach,…

Global economic transformations have never been as dramatic as in the twentieth century. Most countries have experienced radical changes in the standards of income per capita, technology, fertility, mortality, income inequality and the extent of democracy in the course of the past century. It is the goal of many disciplines--economics, history,…

Two methods for promoting peer collaboration among students conducting research were examined. Student interaction was structured using either computer-mediated conferencing (online threaded discussion) or the fishbowl technique. Both techniques produced similar levels of student participation. Questionnaire results indicated that the fishbowl…

The problems caused by a lack of standardized definition of behavior disorders in children are discussed, including differences in identification procedures and widely varying prevalence figures. The significance of environmental intolerance and the instability of many behavior problems over time are described. (Author/MH)

In a nonrandomized or observational study, propensity scores may be used to balance observed covariates and trajectory groups may be used to control baseline or pretreatment measures of outcome. The trajectory groups also aid in characterizing classes of subjects for whom no good matches are available and to define substantively interesting groups…

Recent findings from a Mathematica study comparing the performance of teachers prepared via alternative and traditional routes have been interpreted to suggest that policymakers and practitioners should expand the use of fast-entry alternative routes and seek teachers trained through such programs, as they presumably perform as well in the…
