A latent variable modeling procedure is discussed that can be used to test if two or more homogeneous multicomponent instruments with distinct components are measuring the same underlying construct. The method is widely applicable in scale construction and development research and can also be of special interest in construct validation studies.…

This research uses the nationally representative Beginning Postsecondary Study: 2003-2009 to investigate the relative significance in upward transfer of individual and institutional factors for different groups of students, considering their state policy contexts of variable support for improved articulation and transfer between 2-year and…

Do multiple choice unit tests reflect what students have learned during the unit? The day before the administration of a county-mandated multiple choice test, two classes were shown a topic they had not previously seen, and told it would be on the test. One class was shown the same material and told it was not important, and two classes were not…

The Baccalaureate Nursing program in San Antonio, Texas experienced a decrease in National Council Licensure Examination for Registered Nurses (NCLEX-RN) on the first attempt for students graduating between 2009 and 2014 without a clear explanation for the decline. The purpose of this quantitative non-experimental correlational study was to…

Basic arithmetic forms the foundation of the math courses that students will face in their undergraduate careers. It is therefore crucial that students have a solid understanding of these fundamental concepts. At an open-access university offering both two-year and four-year degrees, incoming freshmen who were identified as lacking in basic…

Decisions about instruction, research, or policy often require the interpretation of student assessment scores. Increasingly, attitudinal variables are included in an assessment strategy, and it is important to ensure that interpretations of students' attitudinal status are based on instrument scores that apply similarly for diverse students. In…

The paper aims at elaborating a strategy regarding students' admission at the colleges of technology in the western region of Saudi Arabia. Purposely, the study surveys the opinion of the students attending the Jeddah College of Technology (J.C.T) and reports on seven socio-economic factors, specifically, the "J.C.T. evaluation system,"…

As a part of an opening course survey, data on eye color and gender were collected from students enrolled in an introductory statistics course at a large university over a recent four year period. Biologically, eye color and gender are independent traits. However, in the data collected from our students, there is a statistically significant…

The purpose of the current quantitative correlational study was to investigate the relationship the qualifications of special education teachers and their preferred writing instruction method either formulaic or process writing. The study investigated the relationship between professional development in writing instruction, years of experience,…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

The purpose of this study was to evaluate the impact of Achieve3000, a differentiated online literacy curriculum, on students' scores on the California State Test (CST). In the 2011-12 school year, 1,957 students in Chula Vista began using Achieve3000's solutions in 3rd through 8th grade. Using a form of propensity score matching called Inverse…

Although peer influence is a salient predictor of delinquency, how it operates in the etiology of runaway behavior is not fully understood. Using data from the National Longitudinal Study of Adolescent Health, this study demonstrates the importance of taking peers into account in understanding the etiology of running away. The findings suggest…

This mixed, causal-comparative study was an investigation of culture infusion methods and AYP of two different public schools in Chicago, a school that infuses African culture and a school that does not. The purpose of the study was to identify if there was a significant causative relationship between culture infusion methods and Adequate Yearly…

Previous research has shown that participation in programs designed to connect students to campus can increase student success and retention. However, very little of this research has controlled for selections bias. The purpose of this study was to use propensity score matching to control for selection bias while analyzing three campus connection…

The purpose of this paper is to calculate the upper limit of the correlation between normal and dichotomous variables. An empirically obtained correlation should be evaluated in view of this limit, instead of the usual limit of Pearson correlation. (Author)
