Phosphatase and tensin homolog-induced putative kinase 1 gene mutations have been associated with autosomal recessive early-onset Parkinson's disease. To date, no neuropathological reports have been published from patients with Parkinson's disease with both phosphatase and tensin homolog-induced putative kinase 1 gene copies mutated. We analysed…

The recent increase in the availability of infant-directed video material (e.g., "Baby Einstein") and the corresponding increase in the amount of time that infants and toddlers spend viewing them have prompted concern among parents and professionals that these media might impede aspects of cognitive and social development. In contrast, supporters…

Implementation of effective interventions relies on the use of assessment data to adequately describe the learning problem and offer potential solutions. The use of curriculum-based assessment and measurement when combined with the learning hierarchy could offer a paradigm for decision making based on a skill-by-treatment interaction.…

One measure commonly used to assess posttraumatic stress disorder is the PTSD Checklist (PCL). Lang and Stein (2005) extracted 4 subsets of PCL items, validating 2 of them for possible use in screening in primary care settings. The viability of the 4 item subsets was evaluated psychometrically in the present study with a sample of Hurricane…

Previous literature has focused on students' perceptions of participation in experiments, but has not measured the effect of participation on learning. In Study 1, students rated their perceptions of learning about psychology; they compared the classroom experience to experiment participation, reading about psychology, or summarizing a journal…

This experiment tested whether peer approval and disapproval experiences can cause immediate change in children's state self-esteem. Children's narcissistic traits and evaluator perceived popularity were examined as potential moderators. A total of 333 preadolescents (M = 10.8 years) completed personal profiles on the Internet that were ostensibly…

To explore possible reasons for low self-identification rates among undergraduates with learning disabilities (LD), we asked students (38 with LD, 100 without LD) attending two large, public, research-intensive universities to respond to a questionnaire designed to assess stereotypes about individuals with LD and conceptions of ability. Responses…

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7-14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi-dimensional HLP, based on empirical research and standards documents, describes how students…

An active approach allowed undergraduates in Health Sciences to learn the dynamics of peer review at first hand. A four-stage process was used. In "stage 1", students formed self-selected groups to explore specific issues. In "stage 2", each group posted their interim reports online on a specific date. Each student read all the…

The purpose of this article is to discuss specific techniques for the computation of the volume of a tetrahedron. A few of them are taught in the undergraduate multivariable calculus courses. Few of them are found in text books on coordinate geometry and synthetic solid geometry. This article gathers many of these techniques so as to constitute a…

This paper examines whether the results of the earnings equation developed in the over-education/required education/under-education (ORU) literature are sensitive to whether the usual or reference levels of education are measured using the Realized Matches or Worker Self-Assessment methods. The analyses are conducted for all male native-born and…

Examining evaluation theory in cultural context is an important component of evaluating theory; however, it is not the ultimate goal. The foundational element in good evaluation is validity, and appreciating the cultural location of evaluation theory is an important building block in the argument supporting multicultural validity. Multicultural…

There is little doubt of the educational and social merits of developing children and young people's social and emotional capabilities. But there lacks consensus on what these capabilities are; what should be assessed or shown to have developed over time; and the most appropriate methods for doing this. Through the conceptual framework of…

Like peanut butter and jelly, kindergarteners and dinosaurs go well together. Therefore, the authors developed a cross-curricular unit based on the books "All Aboard the Dinotrain" (Lund and Fine 2006) and "Dinosailors" (Lund and Fine 2003). Dinosaur learning centers were used to engage students and address the National Science Education Standards…

The purpose of this study was to examine whether spelling performance in preschool children varied as a function of the method of assessment and letter writing ability. The authors manipulated the motoric element and memory demands of the task by having children spell single words using letter tiles, orally, and by writing. The authors also…
