Despite more than a decade of reform efforts, students continue to experience difficulty understanding and applying statistical concepts. The predominant focus of reform has been on content, pedagogy, technology and assessment, with little attention to instructor characteristics. However, there is strong theoretical and empirical evidence that…

We obtained data from pre- and postcourse questionnaires given in an Introduction to the Psychology Major course taught for 10 semesters and compared these data with institutional outcomes concerning the students' last known major and their graduation status. We found the questionnaire reliably measured (a) vocational identity, (b) knowledge of…

Counterintuitively, Y. Kareev, I. Lieberman, and M. Lev (1997) found that a lower short-term memory capacity benefits performance on a correlation detection task. They assumed that people with low short-term memory capacity (low spans) perceived the correlations as more extreme because they relied on smaller samples, which are known to exaggerate…

A decade ago, S. Aglioti, J. F. X. DeSouza, and M. A. Goodale (1995) published an experiment that has had a big influence on the way that visual information is thought to control human behavior. Their findings have often been simplified as suggesting that action is immune to perceptual illusions. The current authors critically analyze the 4 steps…

This article re-examines material discussed in a recent systematic research synthesis by Craven and Lee. The authors find that two of the interventions for foster children discussed by Craven and Lee were erroneously classified as supported by evidence of efficacy, and one, holding therapy, is shown to be potentially physically harmful to…

In their article, "Disconfirmation of the Predictive Validity of the Self-Appraisal Questionnaire in a Sample of High-Risk Drug Offenders," criminologists Mitchell and MacKenzie (2006) purported to evaluate psychometric properties of the Self-Appraisal Questionnaire (SAQ), the first self-report risk/need measure estimating violent and nonviolent…

This article is a commentary for the special issue on the Early Development Instrument (EDI), a community tool to assess children's school readiness and developmental outcomes at a group level. The EDI is administered by kindergarten teachers, who assess their kindergarten students on 5 developmental domains: physical health and well-being, social…

This paper discusses the evaluation of Web-based tools to support Personal Development Planning (PDP) in order to illustrate issues associated with the introduction and assessment of the effectiveness of online resources. The aims of the evaluation were based on concerns about the very complex situation that offering online resources including PDP…

The Learning Transfer System Inventory (LTSI) was developed to identify a select set of factors with the potential to substantially enhance or inhibit transfer of learning to the work environment. It has undergone a variety of validation studies, including construct, criterion, and crosscultural studies. However, the convergent and divergent…

In the context of current efforts to increase student performance and to close the significant gaps in performance among student subgroups, school researchers and practitioners are paying increasing attention to schools as learning organizations. Unfortunately, the concept of the learning organization is generally vague, and school personnel have…

There is a great need to identify specific instructional methods that effectively promote positive skill development in young children with developmental disabilities. One method that has received strong empirical support with children with autism is Discrete Trial Teaching (DTT); however, the effectiveness of DTT has not been extensively…

School-wide positive behavior support (SWPBS) has been implemented in more than 4,000 schools as a means of addressing problem behavior in a systemic fashion. Preliminary outcomes (e.g., office discipline referrals, suspensions) indicate the effectiveness of SWPBS in decreasing school-wide behavior problems and creating a positive school climate.…

This study examined the psychosocial correlates and psychometric properties of the Self-Assessed Wisdom Scale (SAWS) (Webster, 2003a). Seventy-three men and 98 women ranging in age from 17-92 years (Mean age = 42.77) completed an expanded, 40-item version of the SAWS, the Loyola Generativity Scale, and the Experiences in Close Relationships Scale.…

A method is presented for generalized canonical correlation analysis of two or more matrices with missing rows. The method is a combination of Carroll's (1968) method and the missing data approach of the OVERALS technique (Van der Burg, 1988). In a simulation study we assess the performance of the method and compare it to an existing procedure…

The focus of this report is the Direct Instruction Supervision Code, developed to assess the degree of implementation of the Direct Instruction Follow Through Model. Most of this paper deals with the development, reliability, concurrent validity, and criterion-related validity of the code, which is a classroom observation instrument. The report…
