The purpose of this study was to measure the impact of ARCS-based motivational email messages (MVEMs) on student participation in a free online English for Speakers of other Languages (ESOL) course. The course consisted of 10...
In this study, I investigated the effectiveness of a creativity-support system that I developed in the level editor of a learning game called Physics Playground on improving college students’ creativity. Moreover, I investigated the...
Coefficient Omega was introduced by McDonald (1978) as a reliability coefficient of composite scores for the congeneric model. Interval estimation (Neyman, 1937) on coefficient Omega provides a range of plausible values which is likely...
ABSTRACT The purpose of this study was to examine the effects of argumentation scaffolding on problem-solving outcomes and learner motivation in a Problem-Based Learning course. Undergraduate students enrolled in a mandatory introductory...
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 ...
DIF detection methods identify the difference between the performances of subgroups when the subgroups are matched by examinees' ability level or a proxy variable, such as total test score (Holland & Wainer, 1993). Log-linear Models (LLM...
The purpose of this study was to examine the coaching experience in charitable cause-based endurance training programs, in which participants receive coaching to complete a marathon or similar endurance athletic event in return for...
Trash talk, a behavior mostly seen during athletic competitions, is defined as disparaging, taunting, or boastful comments especially between opponents to intimidate each other. To look at what determinants cause a behavior to be...
The main objective of this study was to investigate the improvement of the accuracy of small sample equating, which typically occurs in teacher certification/licensure examinations due to a low volume of test takers per test...
Meta-analytic techniques have gained great attention in educational, social and behavioral sciences to synthesize and summarize related study results. Most common tradition is to use primary studies with similar designs (correlational or...
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...
While Bayesian meta-analysis has flourished both in methodological and substantive work, group-specific Bayesian modeling remains scarce. Common practice for choosing prior distributions entails using typical non-informative priors....
Take a Breath: A Population-Oriented Prevention Approach Using Mindfulness Training to Impact College Students' Sense of Coherence, Stress Levels, and Help-Seeking Intentions
Mental health concerns and resource utilization has greatly increased on college campuses in recent years (ACHA – NCHA, 2017, AUCCCD, 2012, Bourdon et al., 2018). Campus counseling centers are concerned about their ability to meet the...
Computational thinking (CT) is an essential 21st century skill for people to succeed in the increasingly technological (and interconnected) world. Researchers have explored different interventions to teach students CT skills (e.g., ...
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...
Computational thinking is increasingly recognized as an important skill set to learn for people living in the 21st century, and the middle school years comprise a critical stage to introduce children to computational thinking. Video game...
