Jeffry White – Journal of Educational Research and Practice, 2024
Violations of normality and homogeneity are common in educational data. When this occurs, the use of parametric statistics may be inappropriate. A generalized form of nonparametric analyses based on the Puri and Sen L statistic provides an alternative approach. Using a chi-square distribution, this technique is easy to apply and has significant…

Ayodele, Alicia Nicole – ProQuest LLC, 2017
Within polytomous items, differential item functioning (DIF) can take on various forms due to the number of response categories. The lack of invariance at this level is referred to as differential step functioning (DSF). The most common DSF methods in the literature are the adjacent category log odds ratio (AC-LOR) estimator and cumulative…

Rajagopal, Prabha; Ravana, Sri Devi – Information Research: An International Electronic Journal, 2017
Introduction: The use of averaged topic-level scores can result in the loss of valuable data and can cause misinterpretation of the effectiveness of system performance. This study aims to use the scores of each document to evaluate document retrieval systems in a pairwise system evaluation. Method: The chosen evaluation metrics are document-level…

Harges, Fletcher B. – ProQuest LLC, 2017
Each of the states bordering Mississippi invests large amounts of money in providing children with state-funded pre-k programs in their public schools. However, Mississippi falls behind these states and does not similarly invest in this effort to provide many of its children with the opportunity to attend state-funded pre-k programs. Because…

Nelson, Nickola Wolf; Plante, Elena; Anderson, Michele; Applegate, E. Brooks – Journal of Speech, Language, and Hearing Research, 2022
Purpose: This was an investigation of the dimensionality of oral and written language to test the hypothesis that a two-factor model with sound/word and sentence/discourse language levels would best fit language and literacy data for a population-based sample in the school-age years. Method: A stratified secondary data set of 1,500 participants…

Pretz, Jean E.; Kaufman, James C. – Journal of Creative Behavior, 2017
College admissions decisions have traditionally focused on high school academic performance and standardized test scores. An ongoing debate is the validity of these measures for predicting success in college; part of this debate includes how success is defined. One potential way of defining college success is a student's creative accomplishments.…

Zipser, Nina; Mincieli, Lisa – Assessment & Evaluation in Higher Education, 2018
Using nine years of student evaluation of teaching (SET) data from a large US research university, we examine whether changes to the SET instrument have a substantial impact on overall instructor scores. Our study exploits four distinct natural experiments that arose when the SET instrument was changed. To maximise power, we compare the same…

Loden, Lisa Renee – ProQuest LLC, 2018
Remedial mathematics has been considered the roadblock to obtaining a college degree by students and educators for years. The purpose of this research is to determine the optimal time and delivery method of the three presented (fully module, module with a traditional lecture component, and fully on-line) for teaching remedial mathematics. This is…

Maddocks, Danika L. S. – Gifted Child Quarterly, 2018
Students who are gifted and have a learning disability (GLD) may not be identified, in part because of disagreement regarding appropriate identification criteria. In this study, suggested GLD identification criteria were applied to a nationally representative sample of school-age students to determine the number and characteristics of students…

Carlozzi, Michael – Assessment & Evaluation in Higher Education, 2018
The literature on student evaluations of teaching (SETs) generally presents two opposing camps: those who believe in the validity and usefulness of SETs, and those who do not. Some researchers have suggested that 'SET deniers' resist SETs because of their own poor SET results. To test this hypothesis, I analysed essays by 230 SET researchers (170…

Rashid, Mamunur; Sarkar, Jyotirmoy – Educational Research Quarterly, 2018
Students in an online statistics course were prone to become increasingly disengaged as the semester progressed. In Spring 2015, we took a proactive measure to retain student engagement by introducing a cyber mentoring session. We describe the framework, operation and effectiveness of cyber mentoring in improving students' learning experience and…

Taylor, Mark – Online Submission, 2017
In Africa, approximately 80 million children are working. Africa's 41% child labor rate is nearly twice as high as that in Asia. This study examined whether child labor is a direct result of poverty or of reading and math problems in school. The study analyzed reading and math scores of 62 child laborers and 62 non-child laborers from a farming…

Despain, Deric; North, Teresa; Warnick, Brian K.; Baggaley, John – Journal of Agricultural Education, 2016
Agricultural education can take scientific topics to higher levels, emphasize scientific concepts, involve hands-on learning, and develop interrelationships with the other sciences, thus making the living and non-living world around them relevant for students, potentially supporting a STEM curriculum. As such, in 1996, Utah deemed agricultural…
