The Relationship Between Supplemental Instruction Leader Learning Style and Study Session Design

The Relationship Between Supplemental Instruction Leader Learning Style and Study Session Design

Date: May 2011
Creator: Adams, Joshua
Description: The purpose of this qualitative study was to examine the learning styles of supplemental instruction leaders at a large, public university during the fall 2010 semester and determine whether or not their personal learning styles influenced the way they designed and developed out-of-class study sessions. The total population of supplemental instruction leaders was 37, of which 24 were eligible to participate in the study. Of the 24 eligible supplemental instruction leaders, 20 completed the entire study. Participants in the study included nine male and 11 female supplemental instruction leaders with a median age of 22.25 years-old. Seventeen participants indicated their classification as senior, two as junior, and one as sophomore. Of the participants, 16 indicated white as a race or ethnicity, one indicated Asian, two indicated African American, and one indicated both American Indian/Alaska Native and white. Supplemental instruction leader learning style was assessed using the Kolb Learning Style Inventory. Leaders were then interviewed, and their study sessions were analyzed. Through triangulation of data from learning style, interviews and actual study session documents, four major themes emerged. The four themes were: 1) incorporation of personal experience into study session design, 2) the sense of impact on student learning, 3) a ...

The Effects of Interactive Reviews and Learning Style on Student Learning Outcomes at a Texas State University

The Effects of Interactive Reviews and Learning Style on Student Learning Outcomes at a Texas State University

Date: May 2008
Creator: Adams, Wesley
Description: This study investigated the effects of interactive lessons and learning style on student learning outcomes in self-defense education classes. The study utilized an experimental design that incorporated four self-defense education classes at the University of North Texas (UNT) during the fall semester 2007 (N = 87). A pre-test was administered during the first week of class to determine prior knowledge of the participants. The Visual Auditory Reading/Kinesthetic Inventory (VARK) was used to assess the learning styles of the students and was completed after the pre-test of knowledge was administered. The treatment group received the interactive lesson and the control received a paper review. The difference between the pre and posttest was used as a measure of improvement of the student's learning outcomes. A 2 (treatment/control) by 2 (pretest/posttest) ANOVA with repeated measures was conducted to examine the differential improvement in knowledge across the intervention. Based on the 2-way ANOVA there was a significant difference between the treatment group and the control group based on their learning outcomes. A repeated measures ANOVA was conducted to determine if there was a significant difference between the groups based on the pre and post test scores. Based on the results of a one week ...

High-temperature corrosion of aluminum alloys: Oxide-alloy interactions and sulfur interface chemistry

High-temperature corrosion of aluminum alloys: Oxide-alloy interactions and sulfur interface chemistry

Date: December 2000
Creator: Addepalli, Swarnagowri
Description: The spallation of aluminum, chromium, and iron oxide scales is a chronic problem that critically impacts technological applications like aerospace, power plant operation, catalysis, petrochemical industry, and the fabrication of composite materials. The presence of interfacial impurities, mainly sulfur, has been reported to accelerate spallation, thereby promoting the high-temperature corrosion of metals and alloys. The precise mechanism for sulfur-induced destruction of oxides, however, is ambiguous. The objective of the present research is to elucidate the microscopic mechanism for the high-temperature corrosion of aluminum alloys in the presence of sulfur. Auger electron spectroscopy (AES), low energy electron diffraction (LEED), and scanning tunneling microscopy (STM) studies were conducted under ultrahigh vacuum (UHV) conditions on oxidized sulfur-free and sulfur-modified Al/Fe and Ni3Al(111). Evaporative deposition of aluminum onto a sulfur-covered iron surface results in the insertion of aluminum between the sulfur adlayer and the substrate, producing an Fe-Al-S interface. Aluminum oxidation at 300 K is retarded in the presence of sulfur. Oxide destabilization, and the formation of metallic aluminum are observed at temperatures > 600 K when sulfur is located at the Al2O3-Fe interface, while the sulfur-free interface is stable up to 900 K. In contrast, the thermal stability (up to at least 1100 ...

Higher Education and Entrepreneurship: The Relation between College Educational Background and Small Business Success in Texas

Higher Education and Entrepreneurship: The Relation between College Educational Background and Small Business Success in Texas

Date: May 2005
Creator: Al-Zubeidi, Mohammad
Description: This study examined the relationship between success of small businesses and the educational backgrounds of their owners. A survey composed of questions concerning demographics, educational backgrounds, and business success was mailed to 1100 businesses in Dallas, Denton, and Tarrant counties in Texas. There were 228 usable responses which were analyzed by using the Statistical Package of Social Sciences (SPSS12). Data were sorted so that educational level, sales volume, number of employees, and longevity, were identified on a 5-point ordinal scale. Educational major was identified on a 5-point nominal scale. Pearson's correlation was used to determine whether relationships existed between founders' educational background and small business success. Spearman's correlation was used to determine the direction and strength of the relationships. Then educational level and major were combined with age, gender, ethnicity, and industry, to determine the relationships between founders' educational background, and business success. For this purpose a canonical correlation was used. Five opinion questions concerned influence of college education on business success among college graduates and non-college graduates were identified on a 5-point Likert scale and tested using one-way ANOVA, and independent sample t-test. When educational level and major were the only predictors of business success, a statistically significant relationship ...

Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes

Predictive Relationships among Learner Characteristics, Academic Involvement, and Doctoral Education Outcomes

Date: December 2011
Creator: Anderson, Baaska
Description: The literature identifies multiple factors pertinent to learner characteristics and learning experiences that may promote doctoral education outcomes, and yet little quantitative research has examined relationships between those factors deemed important in the effectiveness of doctoral education. This study sought to examine predictive relationships among doctoral students’ learner characteristics, their involvement in mentorship and intellectual community, and doctoral education outcomes. Using Astin’s theory of involvement and the literature on signature pedagogies in doctoral education as conceptual guides, a survey instrument was constructed for the purpose of measuring variables identified as relevant to the effective formation of scholars. Central to the conceptualization of this study was academic involvement as represented by mentorship and intellectual community. The instrument was validated in a two-stage pilot testing process and administered to doctoral candidates at three public Texas higher education institutions. Of the 217 participants, the majority were female, White (Non-Hispanic), US citizens, and were pursuing education doctorates. Data were analyzed using multivariate statistical analyses. Reliability and validity estimates indicated psychometric integrity of the 20 observed variables measured to represent the constructs of mentorship and intellectual community. Results indicated that doctoral students’ learner characteristics were not notably predictive of doctoral students’ degree of involvement in ...

The Anatomy of Academic Dishonesty: Cognitive Development, Self-Concept, Neutralization Techniques, and Attitudes Toward Cheating

The Anatomy of Academic Dishonesty: Cognitive Development, Self-Concept, Neutralization Techniques, and Attitudes Toward Cheating

Date: August 2004
Creator: Arvidson, Cody Jean
Description: This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive ...

College Student Adaptability and Greek Membership: A Single Institution Case Study

College Student Adaptability and Greek Membership: A Single Institution Case Study

Date: May 2007
Creator: Ayres, Amy R.
Description: Since the birth of the United States in 1776, Greek-letter societies have been an integral part of American higher education. Research on the impact of Greek membership varies at best, and often is in conflict from study to study. This study surveyed students affiliated with Greek-letter organizations at the University of North Texas. The research examined the college adaptability of Greek students by gender in five areas: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, and attachment to the institution. The study, conducted in the spring of 2006 at the University of North Texas had 80 respondents. The Student Adaptability to College Questionnaire (SACQ) consisted of 67 items on a 9-point scale. The SACQ is designed to assess how well students adapt to the demands of the college experience. Raw scores and percentile rankings were determined by t-test calculations. Test scores were expressed through t-scores in relation to the standardized sample. Data show no statistical significance in any of the five areas studied: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, or attachment to the institution. Female participants scored higher on all scales than male participants, indicating a slightly higher level of adjustment, though not enough to be significant. Both ...

The Assessment of Cognitive Development and Writing Aptitude Within Learning Communities

The Assessment of Cognitive Development and Writing Aptitude Within Learning Communities

Date: August 2001
Creator: Barnard, Miriam K.
Description: Learning communities have emerged as an efficient and effective paradigm for improving undergraduate education, especially for entering freshmen. The academy has become increasingly interested in learning outcomes and student retention, especially as they are related to the assessment of various approaches to educating the whole student. Learning community pedagogy has developed through rigorous research. However, little is known about the impact of this pedagogy upon college students' cognitive development and writing aptitude. Cognitive development theory has been most significantly influenced by the work of William G. Perry, Jr. Though no theory exists which would address the stages of writing development in university students, many composition theorists suggest a correlation between cognitive development and writing aptitude. This study measured cognitive development and writing aptitude in learning community students and non-learning community students, matching them for SAT scores, high school grade point averages, gender, and ethnicity. The research questions of interest were: 1) How does participation in a learning community affect students' cognitive development; and 2) How does participation in a learning community affect students' writing aptitude? The participants were pre- and post-assessed for cognitive development, using the Measure of Intellectual Development (MID). Additionally, participants were preand post-assessed for writing aptitude, using ...

Living-learning communities and ethnicity: A study on closing the achievement gap at Regional University

Living-learning communities and ethnicity: A study on closing the achievement gap at Regional University

Date: May 2010
Creator: Bewley, Jason Loyd
Description: This quasi-experimental study examined the impact of living-learning communities on GPA and fall-to-fall retention rates for college freshmen at Regional University (RU). The specific focus of this study was the effect of these communities on students of different ethnic groups and on the potential of these communities to reduce the academic performance gap. RU was a small public university that offered both undergraduate and graduate degree programs. RU required all freshman students to live on campus in living-learning communities beginning with the 2007-2008 academic year. This study utilized the 343 student freshman cohort class of 2008 in the living-learning communities as the treatment group. This treatment group was compared against the 193 student freshman cohort class of 2008 living off campus and against the 643 student freshman cohort class of 2006 living on campus prior to the implementation of living-learning communities. In addition, the statistics were analyzed by ethnicity to examine the impact of these communities on White, Hispanic, African American, and Native American students and their ability to reduce the academic performance gap. The research revealed that the communities implemented at RU were not statistically significant at improving academic performance or at reducing the achievement gap. The results of ...
