The purpose of this research was to conceptualize an R & D based learning-to-innovate (LTI) model. The problem to be addressed was the lack of a theoretical L TI model, which would inform science pedagogy. The absorptive capacity (ACAP) lens was adopted to untangle the R & D LTI phenomenon into four learning processes: problem-solving via…

The purpose of this study was to determine pre-service and in-service science and mathematics teachers' perceptions of the characteristics of a professional teaching environment. The study further investigated the relationships of field placement contexts and grade levels on pre-service teachers' perceptions of importance and availability of…

Background: Positive behaviour support (PBS) emphasises multi-component interventions by natural intervention agents to help people overcome challenging behaviours. This paper investigates which components are most effective and which factors might mediate effectiveness. Method: Sixty-one staff working with individuals with intellectual disability…

To identify the most important competencies for college graduates to succeed in the 21st century workforce, we conducted an analysis of the Occupational Information Network (O*NET) database. O*NET is a large job analysis operated and maintained by the U.S. Department of Labor. We specifically analyzed ratings of the importance of abilities (52…

Critical thinking (CT) has been of longstanding interest among scholars, educators, and others who are concerned with thinking skills. The Watson-Glaser Critical Thinking Appraisal (WGCTA) is the oldest and among the most widely used and studied CT measure. It was constructed around five subscales (or CT skills): inference, recognition of…

This study involved an investigation of the use of Pearson r, tetrachoric r, and Kendall Tau-B coefficients as measures of association for the incomplete principal components analysis of simulated Likert scale attitudinal data, based on a known factor pattern and possessing different types of severe departures from normality. (Author)

It is shown that McDonald's generalization of Classical Principal Components Analysis to groups of variables maximally channels the totalvariance of the original variables through the groups of variables acting as groups. An equation is obtained for determining the vectors of correlations of the L2 components with the original variables.…

Bloomfield's "Linguistics as a Science" (1930/1970), "Language" (1933/1961), and "Language or Ideas?" (1936a/1970), and Skinner's "Verbal Behavior" (1957) and "Science and Human Behavior" (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities…

This study involved an investigation of the use of Pearson r, tetrachoric r, phi, phi/phi maximum, and Kendall Tau-B coefficients as measures of association for the incomplete principal components analysis of simulated Likert scale attitudinal data, based on a known factor pattern and possessing different types of severe departures from normality.…

This study examines how rapid automatized naming (RAN) components-articulation time and pause time-develop from kindergarten to the end of first grade and how RAN components are related to different reading measures and to RAN total time. Sixty-two children were administered RAN tasks in kindergarten and at the beginning and end of Grade 1.…

This article reviews the development of a new measure to assess children's perceptions of intergenerational boundary violations in families. The Boundary Violations Scale is a theoretically derived instrument consisting of 12 items. Principal components analysis using data from 119 young adolescents from diverse ethnic backgrounds (i.e., 56%…

An inquiry into methods of assessing the ability of non-English speaking children, conducted with the aim of devising new tests which can be used to assess the abilities of children from a different cultural background and with a poor knowledge of English, is discussed in this book. Cross-cultural tests which are essential in a multi-racial…
