The academic performance of a student in a university is determined by a number of factors, both academic and non-academic. Student that previously excelled at the secondary school level may lose focus due to peer pressure and social lifestyle while those who previously struggled due to family distractions may be able to focus away from home, and…

Peer assessment can be conducted online with rapid development of online learning technology. The current study was conducted empirically to investigate peer rating accuracy and student learning outcomes in online peer assessments, comparing compulsory and voluntary peer assessment. Section 1 (N = 93) was assigned to the voluntary group and…

Self-generated information is better recognized and recalled than read information. This so-called generation effect has been replicated several times for different types of stimulus material, different generation tasks, and retention intervals. The present study investigated the impact of individual differences in learners' disposition to engage…

Context: The accuracy of summative assessment scoring and discriminating the level of knowledge in subject matter is critical in fairness to learners in health care professional programs and to ensure stakeholders of competent providers. An evidence-based approach to determine examination quality for the assessment of applied knowledge is…

Certain planned-missing designs (e.g., simple-matrix sampling) cause zero covariances between variables not jointly observed, making it impossible to do analyses beyond mean estimations without specialized analyses. We tested a multigroup confirmatory factor analysis (CFA) approach by Cudeck (2000), which obtains a model-estimated…

Much research in autism spectrum disorders (ASD) has focused on the development of efficacious interventions to address the core deficits of ASD. However, the heterogeneous nature of ASD complicates the development of such interventions. With great heterogeneity in the expression of ASD's core deficits, it is unlikely that there is a one size fits…

This dissertation investigates the morphological and morphosyntactic processing of case-marking by native and nonnative speakers of Turkish, through behavioral and electrophysiological responses. The study explores the locus of case processing costs during first (L1) and second language (L2) word recognition both in isolation and in sentences. It…

Background: Lowering the cost of assessing clinicians' competence could promote the scalability of evidence-based treatments such as cognitive behavioral therapy (CBT). Aims: This study examined the concordance between clinicians', supervisors' and independent observers' session-specific ratings of clinician competence in school-based CBT and…

Social emotional skills and competencies are integral to student success at home, school, and in the larger community. Extant research also consistently demonstrates that social emotional skill deficits are associated with various adverse outcomes. Universal screening for social emotional and behavioral risk in schools facilitates early…

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in…

The author presents a three-step process for selecting participants for any study of a social phenomenon that occurs between people in locations and at times that are difficult to observe. The process is described with illustrative examples from a previous study of help giving in a community of learners. This paper includes a rationale for…

Access to adequate anatomical specimens can be an important aspect in learning the anatomy of domestic animals. In this study, the authors utilized a structured light scanner and fused deposition modeling (FDM) printer to produce highly accurate animal skeletal models. First, various components of the bovine skeleton, including the femur, the…

Background: The aim of this study was to verify the accuracy of anthropometric equations to estimate the body density (BD) of adults with Down syndrome (DS), and propose new regression equations. Materials and methods: Twenty-one males (30.5 ± 9.4 years) and 17 females (27.3 ± 7.7 years) with DS participated in this study. The reference method for…

We used data simulations to test whether composites consisting of cohesive subtest scores are more accurate than composites consisting of divergent subtest scores. We demonstrate that when multivariate normality holds, divergent and cohesive scores are equally accurate. Furthermore, excluding divergent scores results in biased estimates of…

Introduction: The relational characteristics of an answerer on a social networking site can be used as cues to assess the credibility of an answer. This study examined the effects of different numbers of followers and friends of an answerer on readers' perceived credibility of an answer posted by the answerer in the context of Facebook. Method: We…
