Retention: Course Completion Rates in Online Distance Learning (open access)

Retention: Course Completion Rates in Online Distance Learning

Online courses in higher education have a reputation for having a lower course completion or retention rate than face-to-face courses. Much of this reputation is based upon anecdotal evidence, is outdated, or is on a small scale, such as a comparison of individual courses or programs of instruction. A causal-comparative analysis was conducted among 11 large, high research public universities. The universities were compared to each other to determine if differences existed between online and face-to-face course completion; undergraduate and graduation online course completion was analyzed for differences as well. The findings suggested the magnitude of the differences between online and face-to-face completions rates was small or negligible. The area which showed a higher magnitude of difference was in the comparison between undergraduate and graduate online course completion; the practical significance could be worth considering for educational purposes.

The Relationship of Peer Leadership Employment to Academic Outcomes in Texas Institutions of Higher Education (open access)

The Relationship of Peer Leadership Employment to Academic Outcomes in Texas Institutions of Higher Education

The purpose of this quantitative study was to examine the relationship of participation and involvement in an undergraduate student success program to academic success and persistence among students in three programs sponsored by the Texas Higher Education Coordinating Board (THECB): the G-Force Collegiate Work-Study Mentorship Program, the Advancement Via Individual Determination (AVID) for Higher Education (AHE) program, and the THECB work-study program. The sample was identified using data from the THECB during the 2009-2013 academic years. Compared to THECB work-study students, significantly more AHE and G-Force students persisted toward graduation while engaged in the program (p < .001). ANOVA indicated that AHE students had a higher average GPA compared to G-Force and THECB work-study students, controlled for gender, race/ethnicity, pre-program GPA, and length of time in the position. Regression analyses found no statistically significant relationship between program associations and persistence towards graduation or GPA. Results suggest that although participation in a peer leadership programs such as AHE and G-Force encourage greater academic achievement and persistence, there is no direct relation to the achievement of these outcome variables. Implications of the study suggest the need for a deeper analysis into elements of peer leadership programs that contribute to student success, an …

Photo-induced Toxicity of Deepwater Horizon Spill Oil to Four Native Gulf of Mexico Species (open access)

Photo-induced Toxicity of Deepwater Horizon Spill Oil to Four Native Gulf of Mexico Species

The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions of barrels of crude oil into the Gulf of Mexico (GoM). Photo-induced toxicity following co-exposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab (Callinectes sapidus) are an important commercial and ecological resource in the Gulf of Mexico and their largely transparent larvae may make them sensitive to PAH photo-induced toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, transparent eggs. These characteristics may result in mahi-mahi embryos being at particular risk from photo-induced toxicity. Red drum (Sciaenops ocellatus) and speckled seatrout (Cynoscion nebulosus) are both important fishery resources in the GoM. They spawn near-shore and produce positively buoyant embryos that hatch into larvae in about 24 h. The goal of this body of work was to determine whether exposure to UV as natural sunlight enhances the toxicity of crude oil to early lifestage GoM species. Larval and embryonic organisms were exposed to several dilutions of water accommodated fractions (WAF) from several different oils collected in the field under chain of custody during the 2010 spill and two to three gradations of natural …

Professional Learning Community Dimensions in a North Texas Elementary School’s Culture and Their Impact on Reading and Math Student Growth Scores (open access)

Professional Learning Community Dimensions in a North Texas Elementary School’s Culture and Their Impact on Reading and Math Student Growth Scores

The purpose of this mixed methods study was to determine which dimensions, as represented by the Professional Learning Community Assessment – Revised dimensions, are present in the environment of North Texas elementary schools and their impact on student growth. A survey design was utilized in which elementary principals and teachers in a selected school district completed the Professional Learning Community – Revised survey developed by Hipp and Huffman (2009), to gather perceptions of PLC implementation within their school environments as well as reflect strengths and needs regarding each dimension. The results of the survey were analyzed and one-to-one interviews were completed to clarify and support survey results. Bivariate and multiple regression analysis were used to determine correlations between dimensions present in a school’s environment and their impact on student growth. The study found a statistically significant relationship between the dimensions of shared values and vision and shared personal practice and math growth. Although PLCA-R dimensions were not found to be statistically significant in predicting reading and math growth, the effect sizes were notable at 22.4% for reading growth and 15.8% for math growth. This study’s findings provide important information which educators can use to implement practical application of Professional Learning …

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes (open access)

Levanten La Mano Si Me Entienden: Receptive Bilinguals’ Linguistic and Cultural Perceptions in Secondary Spanish Classes

Receptive bilinguals have been in a dilemma of knowing just enough Spanish to write and aurally comprehend the curriculum at the beginning-intermediate levels of a Spanish language course. This dichotomy in classrooms with mixed-ability learners has created a need to reconsider placement and pedagogical structures tailored for these students in foreign language courses. Thus, this descriptive study examined the perceptions of receptive bilinguals, drawn from two secondary Spanish courses regarding receptive bilinguals’ language use, personal Spanish language abilities and confidence, personal beliefs about the language, and contentment with the course. For this study, 31 participants were selected from two public high schools in a suburb of a large metropolitan area in north Texas. Two surveys, a listening assessment and an online questionnaire, were administered at the end of the academic year. The Likert questionnaire items were analyzed using SPSS software, while open-ended questions were coded for recurrent themes. Analyses revealed four major findings. First, with regard to influence on language use, participants’ grandparents created the most interaction with the Spanish language when compared with the other family groups. In addition, Spanish influence through television, literature, radio, and music contributed to students’ early childhood Spanish learning. Second, as to language preference, …

Community-based Participatory Research: HIV in African American Men Who Have Sex with Men (open access)

Community-based Participatory Research: HIV in African American Men Who Have Sex with Men

To date, traditional behavioral interventions have done little to reduce the prevalence and transmission of HIV among African American men who have sex with men (AAMSM), a highly at risk group. Some researchers theorize that the lack of success may be because these interventions do not address contextual factors among AAMSM. Community-based participatory research (CBPR) is one approach to research with the potential to lead to effective interventions in the future. CBPR is a collaborative, mixed-methods and multidisciplinary, approach to scientific inquiry, which is conducted with, and within, the community. The current study follows the CBPR approach to engage and develop a relationship with the African American communities in the Dallas/Fort Worth Metroplex. Contextual issues were discussed in order to identify emerging themes regarding HIV health related issues among AAMSM to provide the groundwork for continued CBPR research and future interventions with AAMSM in the Dallas/Fort Worth Metroplex. To accomplish this goal, researchers began the CBPR process by conducting interviews and focus groups with a sample of approximately 62 (34 from key informant interviews, 28 from focus groups [gender balanced]) AIDS service organization leaders and workers, advocates, medical doctors and community members with first-hand knowledge of HIV health issues in …

School and Community Partnerships: Effect on At-risk Elementary Student Populations (open access)

School and Community Partnerships: Effect on At-risk Elementary Student Populations

The purpose of this study was to investigate the current practices of school and community partnerships in five North Texas elementary schools. In addition, the study focused on the influence community partnerships have on at-risk students based on at-risk indicators data. The literature revealed that when schools, parents, and families work together, students tend to earn higher grades, attend school more regularly, stay in school longer, and enrolled in coursework beyond high school. The target population included approximately 350 administrators, teachers, and paraprofessionals from five North Texas elementary schools. Also included were the respective partners from each of the five elementary schools. This research included online survey instrument and data were gathered and analyzed through a combination of statistical procedures and descriptive and inferential statistics. The results may provide other schools with a profile of school and community partnerships that can be implemented as a method to help their at-risk student populations. Findings included a descriptive analysis of factors that contributed to the success of community engagement efforts as well as those factors that limited those efforts. A secondary purpose of this study was of continuous improvement in developing these approaches through a goal-setting approach. Schools included in the study …

Student and Family Perspectives on Gifted and Advanced Academics Participation for African American High School Students (open access)

Student and Family Perspectives on Gifted and Advanced Academics Participation for African American High School Students

Many students and their families do not understand the impact of students’ involvement in gifted or advanced academics educational programs and their potentially positive effects and challenges. Nationally African American students are underrepresented in gifted and advanced academics courses in high schools; however, African American students and families often do not advocate for their inclusion in these educational pathways. A survey of literature supporting this study of voices of African American families concerning gifted and advanced academics participation focused on (1) the historical underpinnings for equity and excellence for African American and for gifted and advanced academics learners, (2) how the lack of an agreed upon definition of gifted and advanced academics by the professional field might contribute to the problem, and (3) how African American parents made educational decisions for and with their children, especially concerning college. Employing semi-structured interviews and a focus group, this qualitative case study examined how four students from each of three groups, gifted and talented, advanced academics, and neither, and a representative group of their parents perceived these programs and their children’s involvement in them within the framework provided by a single school district. African American families in this study asked for a partnership …

Back on the Home Front: Demand/Withdraw Communication and Relationship Adjustment Among Student Veterans (open access)

Back on the Home Front: Demand/Withdraw Communication and Relationship Adjustment Among Student Veterans

Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was …

Predicting Latino Male Student Retention: the Effect of Psychosocial Variables on Persistence for First-year College Students at a Southwest University (open access)

Predicting Latino Male Student Retention: the Effect of Psychosocial Variables on Persistence for First-year College Students at a Southwest University

The purpose of this study was to investigate and predict Latino male student retention using ACT’s Engage College survey at a research university in the southwestern region of the U.S. ACT’s Engage survey was designed to predict first-year college retention using 10 psychosocial measures. However, no empirical study exists to support ACT’s claim especially for Latino male students. Data from a four-year research university between 2009 and 2011 were analyzed with logistic regression. Logistic regression analysis was performed for the whole sample (N = 8,061) and for the Latino male subsample (n = 860). In the entire sample’s first regression model, high school grade quartile and SAT score as well as demographic variables were used as predictor variables. In this model, the independent variables of high school grade point average quartile, SAT score, gender, and race made statistically significant contributions to the model (Nagelkerke R2 = .031, p < .01). In the entire sample’s second regression model, ACT’s 10 psychosocial variables were added to the first regression model as predictor variables. Results indicated the instrument was valid for the freshmen as a whole because five out of 10 psychosocial measures displayed statistically significant odds ratios (ORs) for predicting retention: (a) …

The Forty-fifth Illinois Volunteer Infantry Regiment: the Washburne Lead Mine Regiment in the Civil War

Access: Use of this item is restricted to the UNT Community
Of the roughly 3,500 volunteer regiments and batteries organized by the Union army during the American Civil War, only a small fraction has been studied in any scholarly depth. Among those not yet examined by historians was one that typified the western armies commanded by the two greatest Federal generals, Ulysses S. Grant and William T. Sherman. The Forty-fifth Illinois Volunteer Infantry was at Fort Donelson and Shiloh with Grant in 1862, with Grant and Sherman during the long Vicksburg campaign of 1862 and 1863, and with Sherman in the Meridian, Atlanta, Savannah, and Carolinas campaigns in the second half of the war. These Illinois men fought in several of the most important engagements in the western theater of the war and, in the spring of 1865, were present when the last important Confederate army in the east surrendered. The Forty-fifth was also well connected in western politics. Its unofficial name was the “Washburne Lead Mine Regiment,” in honor of U.S Representative Elihu B. Washburne, who used his contacts and influences to arm the regiment with the best weapons and equipment available early in the war. (The Lead Mine designation referred to the mining industry in northern Illinois.) In addition, …
