When developing a test, it is essential to ensure that the test is free of items with differential item functioning (DIF). DIF occurs when examinees of equal ability, but from different examinee subgroups, have different chances of...
In research synthesis, researchers may aim at summarizing peoples' attitudes and perceptions of phenomena that have been assessed using different measures. Self-report rating scales are among the most commonly used measurement tools to...
Children's emergent literacy skills have been found to be predictive of concurrent and subsequent academic achievement. Proponents of a nurture-driven approach to learning posit that children's linguistic competencies are associated with...
This study is a quantitative, quasi-experimental inquiry into the effectiveness of motivational instructional strategies on undergraduate math students' subject learning. Secondarily, it examines the effects of the motivational...
This study introduces a longitudinal diagnostic classification model, called the LTA+HDCM, which is a fusion of latent transition analysis (LTA; Collins & Flaherty, 2002; Collins & Wugalter, 1992) and the hierarchical diagnostic...
Body Image Dissatisfaction (BID) has been considered as one of the important antecedents of Social Physique Anxiety (SPA; Hart, Leary, & Rejeski, 1989). However, the context of romantic relationship has yet to be considered in extant...
A Self-Determination Theory Perspective on Burnout Among Korean Athletes: Perceived Coaching Behaviors and Satisfaction/Thwarting of Psychological Needs
The purpose of this study was to examine the relationship between perceived coaching behaviors and athlete burnout, and to investigate the mediation effects of psychological need satisfaction/thwarting and self-determined motivation on...
In structural equation modeling (SEM), researchers use the model chi-square statistic and model-fit indexes to evaluate model-data fit. Root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker-Lewis index ...
Primary studies are using complex models more and more. Slopes from multiple regression analyses are reported in primary studies, but few scholars have dealt with how to combine multiple regression slopes. One of the problems in...
Over the years a variety of indices have been proposed to summarize regression analyses. Unfortunately the proposed indices are only appropriate when meta-analysts want to understand the role of a single predictor variable in predicting...
The dissertation explored the efficacy of using a POMDP to select and apply appropriate instruction. POMDPs are a tool for planning: selecting a sequence of actions that will lead to an optimal outcome. RTI is an approach to instruction, ...
The purpose of the study was to examine the effects of stroboscopic training on intermediate tennis players' anticipatory response accuracy, response time, and self-efficacy. Participants (N=30) completed six on-court training sessions, ...
Computer-based simulations are commonly used to train students when it is exceptionally expensive or very unsafe to practice the skill in the actual situation. Despite the promise of simulative environments, there is an inadequacy in the...
Productive failure refers to an instructional strategy that tasks students with attempting to solve a complex and/or ill-structured problem prior to instruction about the topic. In their problem-solving attempts, the students are...
The Impact of Rater Variability on Relationships among Different Effect-Size Indices for Inter-Rater Agreement between Human and Automated Essay Scoring
Since researchers investigated automatic scoring systems in writing assessments, they have dealt with relationships between human and machine scoring, and then have suggested evaluation criteria for inter-rater agreement. The main...
The problem of class imbalance has become frequent, and missing data also are often a predicament in the social sciences. In the literature, the two problems have been debated substantially and separately. Class imbalance has been shown...
The purpose of this study was to develop, refine, and validate a conceptual model of Group Work Contribution (GWC) explaining how undergraduate students participate in and contribute to group work. In addition, this study intended to...
Although self-regulated learning has been identified as important for students in academic settings, the construct of teacher self-regulation is less well understood. The literature on teacher self-regulation is reviewed in this...
This experimental study was intended to examine whether game-based learning (GBL) that encompasses four particular game characteristics (challenges, a storyline, rewards, and the integration of game-play with learning content) in the...
Differential Item Functioning Identification Strategy for Items with Dichotomous Responses Using the Item Information Curve: A Weighted Area Method (WAM)
Frequently researchers base their decisions and interpretations on conclusions drawn from data analyses, but what happens when the data used in the analyses are collected from unreliable instruments or surveys? The instrument may include...
