An asynchronous online discussion (AOD) is one format of instructional methods that facilitate student-centered learning. In the wealth of AOD research, this study evaluated how students' behavior on AOD influences their academic outcomes. This case study compared the differential analytic methods including web log mining, social network analysis…

Context: Collaboration within school teams is considered to be important to build the capacity school teams need to work in a data-based way. In a school characterized by a strong collaborative culture, teachers may have more access to the knowledge and skills for analyzing data, teachers have more opportunity to discuss the performance goals to…

It is tentatively estimated that 25% of people with early Alzheimer's disease (AD) show impaired awareness of disease-related changes in their own cognition. Research examining both normative self-awareness and altered awareness resulting from brain disease or injury points to the central role of the medial prefrontal cortex (MPFC) in generating…

Methods exist for testing the homogeneity of group regression for the case in which there is only one predictor. Studies which have investigated aptitude-treatment interactions have adopted the homogeneity of regressions test as standard methodology for assessing the difference in regression slopes across treatments. Additional statistical…

Multiple regression analysis with data from each of three recent U.S. national surveys is used to estimate the direct effects of each of 10 independent variables on the reported marital happiness of white males and females ages 18 through 59. All of the estimated direct effects are weak or nil. (Author)

The purpose of this study was to broaden the aptitude by treatment interaction paradigm. The relationship between memory span and performance in two different transfer conditions was examined, and task involvement and anxiety were considered as they contribute to the relationship between aptitudes and performance.

This report is an attempt to analyze the aggression which occurs within extended dyadic interchanges of parent and child, husband and wife, or sibling and peers. An argument is made for a "performance" theory of children's noxious behaviors based on the assumption that most children, exposed to modeling and reinforcing contingencies through which…

For many persons, a satisfying group experience involves reaching a desired level of personal participation. The experimental laboratory studies of communication network groups have been the most rigorous attempts at understanding the effects of differential participation. It has been shown that centrality of a subject's position influences: (1)…

The development of a scale for measuring the interaction of Mexican Americans with Anglos (Anglo Interaction Index) was discussed. The scale was part of a larger investigation on status mobility among middle-class Mexican Americans in Texas. Data was collected in Waco (selected for pretesting), Austin, McAllen, and Lubbock. These communities were…

The purposes of this study were (1) to provide an objective description of the supervisor-teacher conference behavior in a micro-teaching situation, (2) to determine the combinations of teacher and supervisor characteristics that predict conference behavior and conference effectiveness, and (3) to determine the supervisor characteristics that…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

This paper presents findings from an inquiry conducted in Australian secondary schools at the Form I level that examined the contributions of selected teaching behaviors to the achievement, attitudes, and attentiveness of students. The investigation was restricted to children in the schools of the Australian Capital Territory (ACT). This…
