One major issue with large-scale assessments is that the respondents might give no responses to many items, resulting in less accurate estimations of both assessed abilities and item parameters. This report studies how the types of items affect the item-level nonresponse rates and how different methods of treating item-level nonresponses have an…

The purpose of this study was to examine the effects of strategic problem solving with peer instruction on college students' performance in physics. The students enrolled in 2 sections of a physics course were studied; 1 section was the treatment group and the other section was the comparison group. Students in the treatment group received peer…

Black and Hispanic students are undeniably underidentified as gifted and underrepresented in gifted education. The underrepresentation of the two largest groups of "minority" students is long-standing, dating several decades, and is a serious area of contention. Most debates focus on the efficacy of traditional intelligence tests with…

Background: Despite doubts voiced on their efficacy, a series of studies has been carried out on the capacity of training programmes to improve academic and reasoning skills by focusing on underlying cognitive abilities and working memory in particular. No systematic efforts have been made, however, to test training programmes that involve both…

Cognitive control dysfunctions, like inhibitory and attentional flexibility deficits are assumed to underlie repetitive behavior in individuals with autism spectrum disorders (ASD). In the present study, prepotent response inhibition and attentional flexibility were examined in 64 high-functioning individuals with ASD and 53 control participants.…

Objective: Increasing numbers of student service members/veterans (SSM/Vs) are enrolling in college. However, little is known about how their previous military experience affects their adjustment to this new role. The present study tested the hypothesis that SSM/Vs who report adjustment problems in college have a higher incidence of posttraumatic…

Epidemiological studies have highlighted a strong male bias in autism spectrum disorder (ASD), however few studies have examined gender differences in autism symptoms, and available findings are inconsistent. The aim of the present study is to investigate the longitudinal gender differences in developmental profiles of 30 female and 30 male…

Background: To describe the characteristics of those with autism spectrum disorder (ASD) treated within a forensic intellectual disability hospital and to compare them with those without ASD. Method: Service evaluation of a cohort of 138 patients treated over a 6-year period. Results: Of the 138, 42 had an ASD. Personality disorders and harmful…

Central to equation solving is the maintenance of equivalence on both sides of the equation. However, when the process involves an interaction of multiple elements, solving an equation can impose a high cognitive load. The balance method requires operations on both sides of the equation, whereas the inverse method involves operations on one side…

I advance a theoretically and empirically-grounded case for designing for and learning from failure, and instantiate it in a learning design called Productive Failure (PF). I describe the key mechanisms and the design principles of PF. The PF learning design comprises a generation and exploration phase followed by a consolidation and knowledge…

This paper discusses a study of students learning core conceptual perspectives from recent scientific research on complexity using a hypermedia learning environment in which different types of scaffolding were provided. Three comparison groups used a hypermedia system with agent-based models and scaffolds for problem-based learning activities that…

The current study aimed to identify the appropriate method of teaching creativity through comparing computer-based instruction with problem-solving instruction. A sample of 50 male students studying in the second grade of junior high school was chosen and divided into two equal groups. Both groups filled out the Torrance Test of Creative Thinking…

The article discusses comparative organizational studies, focusing on change in higher education institutions, and in particular (but not only) on studies that compare organizations in different national settings. It first presents and discusses different approaches to comparison based on a couple of typologies that have been developed to identify…

This comparative case study describes the literacy practices of two groups of adolescents as they sought to solve authentic problems through engineering design processes. Three types of data were collected as the groups addressed these problems: video- and audio-recordings of their conversations; adolescent-generated products; and pre- and…

Facial expressions in sign language carry a variety of communicative features. While emotion can modulate a spoken utterance through changes in intonation, duration and intensity, in sign language specific facial expressions presented concurrently with a manual sign perform this function. When deaf adult signers cannot see facial features, their…
