This study examined the effects of task difficulty on on-task behavior for four students exhibiting low levels of math performance and on-task behavior. Curriculum-based assessments were conducted with each student to define the difficulty level of math tasks for each student based on the individual's rate of accurate performance on computational…

Over the past 2 decades, research has demonstrated that learner collaboration facilitates second language (L2) acquisition (Lapkin, Swain, & Smith, 2002; McDonough, 2004; Storch, 1998, 2004; Swain & Lapkin, 1998). Adopting a sociocultural perspective (e.g., Swain & Lapkin, 1998), the current study compared the effectiveness of collaborative and…

Deaf and hearing students' knowledge of English sentences containing universal quantifiers was compared through their performance on a 50-item, multiple-picture task that required students to decide whether each of five pictures represented a possible meaning of a target sentence. The task assessed fundamental knowledge of quantifier sentences,…

Cognitive performance is affected by an individual's characteristics and the environment, as well as by the nature of the task and the amount of practice at it. Mental performance tests range in complexity and include subjective estimates of mood, simple objective tests (reaction time), and measures of complex performance that require decisions to…

This study examines the cognitive costs of navigation aids in a hypermedia learning task. In a 2(navigable vs. non-navigable) x 2(map vs. content list) experimental design cognitive requirements were measured by users' eye movement data. Additionally, data from users' navigation operations, knowledge acquisition, and subjective evaluation of the…

This paper presents a brief summary of processability theory as proposed by [Pienemann, M., 1998a. "Language Processing and Second Language Development: Processability Theory." John Benjamins, Amsterdam; Pienemann, M., 1998b. "Developmental dynamics in L1 and L2 acquisition: processability theory and generative entrenchment." "Bilingualism:…

Background: Narratives have been used by a number of researchers to investigate the language of children with specific language impairment (SLI). While a number of explanations for SLI have been proposed, there is now mounting evidence that children with SLI have limited memory resources. Phonological memory has been the focus of the research on…

Phonological awareness (PA) is the ability to analyze spoken language into its component sounds and to manipulate these smaller units. Literature review related to PA shows that a variety of factor groups play a role in PA in Mandarin such as linguistic experience (spoken language, alphabetic literacy, and second language learning), item type,…

This booklet focuses on effective mathematics teaching. Drawing on a wide range of research, it describes the kinds of pedagogical approaches that engage learners and lead to desirable outcomes. The aim of the booklet is to deepen the understanding of practitioners, teacher educators, and policy makers and assist them to optimize opportunities for…

It is not known why people move their eyes when engaged in non-visual cognition. The current study tested the hypothesis that differences in saccadic eye movement rate (EMR) during non-visual cognitive tasks reflect different requirements for searching long-term memory. Participants performed non-visual tasks requiring relatively low or high…

Infants younger than 20 months of age interpret both words and symbolic gestures as object names. Later in development words and gestures take on divergent communicative functions. Here, we examined patterns of brain activity to words and gestures in typically developing infants at 18 and 26 months of age. Event-related potentials (ERPs) were…

Extending S. Graham and K. R. Harris's (2003) self-regulated strategy development model, this study examined whether self-regulation procedures would increase the effectiveness of a writing strategies training designed to improve 4th graders' (N = 113) composition skills. Students who were taught composition strategies in conjunction with…

Purpose: To examine the behavioral effects and neural activation patterns associated with implicit semantic processing influences on phonological judgments during reading in children and adults. Method: Whole-head magnetoencephalography (MEG) recordings were obtained from 2 groups, children (9-13 years) and adults, performing a homophone judgment…

This study took a pragmatic approach to examining the effects of task difficulty on L2 oral output. Twenty native English speakers and 59 Japanese students of English at two different proficiency levels produced speech acts of requests and refusals in a role play task. The task had two situation types based on three social variables:…

The aim of the study was to investigate the developmental trajectory of error monitoring. For this purpose, children (age 7-8), young adolescents (age 13-14) and adults (age 23-24) performed a Go/No-Go task and were compared on overt reaction time (RT) performance and on event-related potentials (ERPs), thought to reflect error detection…
