The Correlation Between a General Critical Thinking Skills Test and a Discipline Specific Critical Thinking Test For Associate Degree Nursing Students

The Correlation Between a General Critical Thinking Skills Test and a Discipline Specific Critical Thinking Test For Associate Degree Nursing Students

Date: May 2000
Creator: Reid, Helen
Description: In 1997, NLNAC added critical thinking as a required outcome for accreditation of associate degree nursing (ADN) programs. Until recently general critical thinking tests were the only available standardized critical thinking assessment tools. The emphasis has shifted to discipline specific tools. This concurrent validity study explored the correlation between two critical thinking tests, a general skills test, the California Critical Thinking Skills Test (CCTST) and a discipline specific test, the Arnett Critical Thinking Outcome Evaluation (CTOE). Both tests are based on the same definition of critical thinking. The CCTST, developed in 1990, covers discipline neutral content in multiple choice items. The CTOE, a free entry, written response test developed in 1998, assesses critical thinking in nursing situations using a partial credit model. A convenience sample of 434 sophomore ADN students from 9 programs in Texas completed the demographic survey and critical thinking tests in 1999. The sample was 87.9% female and 74.2% Caucasian, with a mean age of 31, mean GPA of 3.13, mean 3.7 years healthcare employment experience, mean CCTST score of 15.0023 and mean CTOE of 82.69. The sample also included 22.4% current LVNs, 15.7% with prior degrees and 53.5% in the first generation of their family to ...

Date: August 2006
Creator: Tavoc, Tabitha
Description: This causal-comparative and correlational study examined cross-cultural adaptability of randomly selected licensed dental hygienists, 1995-2005 graduates, practicing in the state of Texas and first and second-year dental hygiene students attending 5 randomly selected accredited 2 and 4-year dental hygiene schools in the state of Texas. A sample of 289 individuals: 194 enrolled students and 95 licensed dental hygienists, alumni of the 5 schools, completed the 50-item Cross-Cultural Adaptability Inventory (CCAI ®) and a brief demographic survey. The purpose of this study was to determine if statistically significant differences existed among and between licensed dental hygienists and first and second-year dental hygiene students in the state of Texas on a cross-cultural adaptability measure. The study also examined relationships among and between cross-cultural adaptability scores, as measured by the CCAI, and several independent variables. The data were analyzed by using the Statistical Package of Social Sciences (SPSS 12). Eight hypotheses related to group differences and relationships among and between groups and variables were tested. The groups were compared on total CCAI scores using a t-test, and on subscale CCAI scores simultaneously using a descriptive discriminant analysis (DDA). A 3X2 MANOVA was used to compare all groups simultaneously on subscale CCAI scores. The ...

Creator: Powell, Monica S.
Description: This mixed-methodology study examined a set of award winning dissertations to determine what factors may have led to their receiving recognition by the Association for the Study of Higher Education (ASHE). The study addressed seven specific research questions which were answered via two different research designs: 1) a survey administered to the 27 recipients of the dissertation award, and 2) through the qualitative assessment of a sample of the winning dissertations. The quantitative survey was distributed to recipients of the Association for the Study of Higher Education Dissertation of the Year award from 1979 through 2004. The survey collected specific information on the personal attributes and characteristics of the award recipients, descriptive information about the award winning dissertations, information concerning the quality of the winner's doctoral experiences, the quality of their relationship with their dissertations advisors and the progression of their careers after winning the award. The qualitative assessment involved applying a set of evaluative questions provided by Gall, Gall and Borg to describe a sample of the award winning documents. The results indicated that recipients of the ASHE award were not representative of education doctoral students as indicated by 2004 data. The results of the study also indicated that, ...

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Barton, Mary Edna
Description: Each year, institutions of higher education devote valuable financial and personnel resources in the hope of enhancing student recruitment and matriculation. The purpose of this study was to examine the demographic characteristics, the factors that influenced studentsÂ’ decisions to apply for admission to a university, their educational intentions, and their reasons for not enrolling after they had been admitted. The subjects of the study were first-time freshmen accepted for admission to a mid-size, public, southwestern university who did not enroll for the fall 1997 semester. Statistically significant differences were found when comparing no-shows and enrolled students by gender, ethnicity, age, ACT/SAT score, and distance of their hometown from the university. There were more female no-shows, and more males enrolled than females; a greater percentage of no-shows reported the distance of their hometown to be more than 200 miles; and the mean test score for no-shows was higher. Factors important in the college selection process found to be statistically significant among the groups were: a greater percentage of Minorities than Caucasians reported the importance of the financial aid award or a scholarship offer; students living within 100 miles of the campus reported the proximity of the university as important, advice received ...

Determining the Relationship Between Motivation and Academic Outcomes Among Students in the Health Professions.

Determining the Relationship Between Motivation and Academic Outcomes Among Students in the Health Professions.

Date: May 2007
Creator: Reed, Linda E.
Description: Admissions processes for health professions programs result in students entering these programs academically homogeneous. Yet some students have great difficulty with the programs. Research has shown a limited ability of traditional academic indicators to predict successful outcomes for health professions education. The purpose of this study was to examine the relationship between learning motivation and academic outcomes for students in health professions programs. The Modified Archer Health Professions Motivation Scale (MAHPMS) and a demographic survey were administered at orientation to 131 medical and 29 physician assistant students at the University of North Texas Health Science Center in the fall of 2005. At the end of the semester, the same version of the MAHPMS was administered, and final course grades and semester averages were collected. Descriptive statistics were analyzed for all the study variables. Analysis of variance was utilized to examine within subjects and between subjects differences for the learning motivation scores among programs and demographic categories. Linear regression analyses were used to determine the relationship between learning motivation scores and end-of-semester grades. And finally, logistic regression was performed to explore the ability of the motivation scores to predict academically high-risk students. Approximately three-fourths of the students indicated a preference for ...

Educationally At-risk College Students From Single-parent and Two-parent Households: an Analysis of Differences Employing Cooperative Institutional Research Program Data.

Date: August 2005
Creator: Brown, Peggy Brandt
Description: Using factors of low income, parents' levels of education, and family composition as determinants of educationally at-risk status, study investigated differences between first generation, undergraduate college students from families in lowest quintile of income in the U.S, One group consisted of students from single-parent households and the other of students from two-parent households. Data were from CIRP 2003 College Student Survey (CSS) and its matched data from the Freshman Survey (Student Information Form - SIF). Differences examined included student inputs, involvements, outcomes, and collegiate environments. Included is portrait of low income, first generation college students who successfully navigated U.S. higher education. The number of cases dropped from 15,601 matched SIF/CSS cases to 308 cases of low income, first generation college students (175 from single-parent households and 133 from two-parent households). Most of the 308 attended private, 4-year colleges. Data yielded more similarities than differences between groups. Statistically significant differences (p < .05) existed in 9 of 100 variables including race/ ethnicity, whether or not English was first language, and concern for ability to finance education as freshman. Data were not generalizable to all low income, first generation college students because of lack of public, 4-year and 2-year colleges and universities ...

The Effect of Quality and Color Visual Aids on Immediate Recall, Attitude Toward Speaker, and Attitude Toward Speech

The Effect of Quality and Color Visual Aids on Immediate Recall, Attitude Toward Speaker, and Attitude Toward Speech

Date: May 1999
Creator: Hamilton, Cheryl A. (Cheryl Ann)
Description: Thirty years of empirical research on visual aids have produced inconsistent results--perhaps because the quality and color of those visuals were inconsistent. The purpose of this study was to determine what effects quality and color of instructional transparencies used in an informative speech have on listener recall and attitudes toward speaker and speech. A total of 709 community college and university students in 36 intact classes were randomly assigned to one of four visual treatment groups (poor-quality black/white, high-quality black/white, poor-quality color, or high-quality color) or one of two control groups (no-speech or no-visuals). A videotaped speech was projected onto a large screen at the right of the room; visual aids (each shown for approximately 30 seconds) were projected onto another screen set immediately to the left. Recall was measured by a 10-item multiple choice test; attitude toward speech and speaker were each measured by six seven-item semantic differential scales. Analysis of variance indicated that the type of transparencies used in an informative speech have a definite effect on immediate recall and attitude toward the speech, but no effect on attitude toward speaker. All four treatment groups scored significantly higher on recall than the no-speech and no-visual control groups. Log ...

Enrollment Management in Higher Education: From Theory to Practice

Enrollment Management in Higher Education: From Theory to Practice

Date: August 2000
Creator: Clark, V. Allen
Description: This study investigated enrollment management practices found in higher education. The research identified enrollment management and retention practices described in the higher education literature. These suggested practices were incorporated into a sixty-six question survey that was distributed to a random sample of colleges and universities taken from the 1999 US News and World Report of college rankings. The survey data were used to identify which of the suggested enrollment management practices were of greatest utility. First, the sixty-six items were grouped into 14 categories of enrollment management strategies. Second, the institutional responses for each category were averaged and then correlated with each institution's graduation rate. Finally, each institution's "yes" responses for the entire survey were totaled and correlated with each institution's graduation rate. This study developed a list of the 26 most frequently used enrollment management practices in higher education, and as well, identified the 10 least used enrollment management practices. Given the results of this study graduation rate is not a sufficient criterion to assess enrollment management practices at a college or university. Enrollment management strategies contribute to many institutional and student outcomes; thus, multiple indicators are required to accurately evaluate enrollment management practices.

Ethics of Teaching: Beliefs and Behaviors of Community College Faculty

Ethics of Teaching: Beliefs and Behaviors of Community College Faculty

Date: August 2002
Creator: Scales, Renay Ford
Description: This study examines the ethical beliefs and behaviors of full-time community college faculty. Respondents report to what degree they practice sixty-two behaviors as teachers and whether they believe the behaviors to be ethical. Survey participants engaged in few of the behaviors, and only reported two actions as ethical: (1) accepting inexpensive gifts from students and (2) teaching values or ethics. The participants reported diverse responses to questions about behavior of a sexual nature, but most agreed that sexual relationships with students or colleagues at the same, higher or lower rank were unethical. Additional findings relate to the presence of diversity among the faculty, using school resources to publish textbooks and external publications, selling goods to students, and an expansive list of other behaviors. Findings of this study are compared to results from earlier studies that utilized the same or similar survey instrument with teaching faculty. The study has implications for organizational policy and procedure, for faculty training and development, the teaching of ethics or values in the classroom and for future research.

Factors Influencing Freshmen Students' College Choice at the University of North Texas: a Focus Group Study

Date: August 1997
Creator: Armstrong, Jami J. (Jami Joi)
Description: This study focused on factors that may influence freshmen students when choosing their colleges, specifically those who attend metropolitan universities such as the University of North Texas. In addition to identifying major characteristics of the institution that attract students, it also explored the sources of information that students considered important when making their choice about where to attend college. The primary instrument for gathering the data was focus groups. These informal, small groups provided a format for in-depth discussion and probing questioning about the needs, wants and influential factors driving freshmen college choice. Ten focus groups were held with between six and ten students in a specially designed room on the campus of the University of North Texas. A professional moderator was employed and sessions were observed via a two-way mirror and tape recorded for later transcription. The major questions addressed in the focus groups included: What factors influenced students the most to attend the University of North Texas? What did they consider the level of friendliness on campus? And how did the marketing materials that the university distributed impact their decision to attend? The study found that the factors that most influenced freshmen to attend the University of North ...

Faculty Attitudes Toward Residential and Distance Learning: A Case Study in Instructional Mode Preferences Among Theological Seminary Faculty

Faculty Attitudes Toward Residential and Distance Learning: A Case Study in Instructional Mode Preferences Among Theological Seminary Faculty

Date: May 2003
Creator: Scott, Benjamin G.
Description: Twenty-first century learners have bought into a cafeteria-style mentality for obtaining higher education that learning should be available at the student's convenience. Institutions that ignore this postmodern trend will likely find their applicant pools dwindling along with significant reductions in entering class sizes. Students will simply choose other schools able to provide respected, accredited, and useful learning which fits their busy lifestyles. Since 1987, Dallas Theological Seminary (Texas), a 76-year-old graduate school of theology in the conservative, evangelical, free-church movement, has offered distance learning classes in both extension and print-based delivery models. Because the faculty plays a pivotal role in the successful or unsuccessful implementation of online courses (McKenzie, Mims, Bennett, & Waugh, 2000), the present study uncovered the attitudes of full-time, graduate theological faculty at Dallas Theological Seminary (DTS) regarding distance learning and the likelihood of faculty to adopt this delivery innovation. Bruce Manning's (1976) Trouble-Shooting Checklist (TSC) for Higher Education Institutions was the instrument used in the study. The TSC is a nonparametric test designed to uncover differences between the observed and expected levels of acceptance that a department, program, or institution possesses regarding change toward distance learning in contrast to residential learning. The checklist's two major purposes ...

Faculty Practice Among Commission of Collegiate Nursing Education Accredited Nursing Schools

Faculty Practice Among Commission of Collegiate Nursing Education Accredited Nursing Schools

Date: December 2002
Creator: Roberts, Amy
Description: This descriptive survey study investigated the value of faculty practice among Commission of Collegiate Nurse Education (CCNE) Accredited Nursing Schools. The sample included all CCNE accredited schools that offered a Masters degree. Subjects from the 66 schools in the sample the dean and three Nurse Practitioner faculty who are teaching a clinical course. Response rate was 51% for the deans and 35% for the faculty. The opinions of deans were compared to the opinions of faculty on the views of faculty practice as research and the incorporation of faculty practice in the tenure and merit review system. The results showed faculty and deans differed on the value of faculty practice as research. However, only 6.5 % of statistically significance difference was contributable to whether the response was from a dean of a faculty. There was no significant difference to the inclusion of faculty practice in the tenure and merit review system. Boyer's expanded definition of research was used as a theoretical background. Deans viewed faculty practice more important as compared to the traditional faculty expectation of research than faculty did. The operational definition of faculty practice was that it required scholarly outcomes from the practice. Deans were more willing than ...

Creator: Ellis, Martha M. (Martha McCracken)
Description: The purposes of this research were to determine (1) the extent to which faculty are employed by the types of institutions from which they earned their doctorates in the United States, (2) the extent to which faculty have higher professional rank at employing institutions tat are the same type of institutions as those from which they earned their doctorates, (3) the extent to which female faculty are employed by the types of institutions from which they earned their doctorates, (4) the extent to which female faculty have higher professional rank at employing institutions that are the same type of institutions as those from which they received their doctorates, and (5) the extent of variability across academic disciplines in which faculty are employed by types of institutions from which they earned their doctorates. An exhaustive review of the literature on academic lineage was used to develop this research. All stratified random sample of 260 institutions from 2,873 colleges and universities was selected by Carnegie Foundation classification categories. Institutions were selected at random until the number of faculty members in each category corresponded to the estimated national distribution of faculty across Carnegie classification categories (n=3,940).

The Four Major Education GI Bills: A Historical Study of the Shifting National Purposes and Accompanying Changes in Economic Value to Veterans

The Four Major Education GI Bills: A Historical Study of the Shifting National Purposes and Accompanying Changes in Economic Value to Veterans

Date: December 2000
Creator: Spaulding, Donald James
Description: Benefits for soldiers follow the formation of ancient and present day armies raised for the purpose of extending the national or state will. Veterans' benefits for defenders of the U.S. emerged during the American colonial period. College benefits began after WWII with the GI Bill of Rights. This study examines the variations in purpose for nationally established educational benefits for veterans and the singular value to the veterans of these 5educational benefits. The study begins with an overview of the history of veterans' benefits. Primary emphasis is then placed on the educational portion of the World War II Servicemen's Readjustment Act and the current educational benefit, the Montgomery GI Bill. As the purpose of awarding educational benefits changed from World War II to the latest U.S. war, the Gulf War of 1990-1991, the economic value to the individual veteran also changed. The WWII GI Bill featured an educational provision intended to keep returning veterans out of the changing economy whereas current GI Bills is intended as a recruiting incentive for an all-volunteer force. Correspondingly, the economic value to the individual veteran has changed. Data supporting this study were extracted from historical documents in primary and secondary scholarly studies and writings, ...

Gender differences in college choice, aspirations, and self-concept among community college students in science, mathematics, and engineering.

Access: Use of this item is restricted to the UNT Community.
Date: August 2004
Creator: Starobin, Soko Suzuki
Description: Educational researchers, practitioners, and policy makers have long expressed their concern that gender disparity of academic performance and participation in science and mathematics education continues to increase with educational progress of students through the pipeline. Educational and occupational aspirations, high school experience, external support from family members and significant others appear to be influential factors that develop strong self-concept among female students who aspire to study science and mathematics. Using a national sample of aspirants in science, mathematics, and engineering majors in public community colleges, that participated in the 1996 Cooperative Institutional Research Program American Freshman Survey, this study investigated the influences of students' pre-college experiences on their college choice, aspirations, and self-concept by examining three theoretical structural models. In addition, gender differences were tested by using multiple group analysis. The findings from the multiple group analysis revealed that there was no statistically significant gender difference in predicting college choice, aspirations, and self-concept. The results from the descriptive analysis indicated that the female students were already underrepresented in science, mathematics, and engineering majors. Taken together, the findings challenge researchers, practitioners, and policy makers to examine why the persistent fall off, and how can community colleges support and retain these students ...

Date: August 2007
Creator: Iba, Debra, L.
Description: This study explored the relationship between the personality construct of hardiness and public speaking anxiety. Although hardiness has been widely explored in a variety of anxiety-arousing life events, its relationship with communication anxiety had not been previously studied. Therefore, hardiness, public speaking trait anxiety, and public speaking state anxiety were measured in a course requiring an oral presentation assignment. One hundred fifty students enrolled in a basic speech communication course participated in the study. A statistically significant correlation was revealed between hardiness and trait communication anxiety. Students higher in hardiness reported lower trait communication apprehension in three contexts: 1) meeting, 2) interpersonal, and 3) group. Overall, students did not differ on measures of hardiness and a fourth communication context: public speaking anxiety. Likewise, on measures of hardiness and state public speaking anxiety, students did not differ.

Hardiness, stress, and coping strategies among mid-level nurse managers: Implications for continuing higher education.

Date: May 2001
Creator: Judkins, Sharon Kay
Description: This study investigated relationships among hardiness, stress, and coping strategies among mid-level nurse managers in hospitals. Coping strategies were hypothesized to be positively related to stress. In addition, hardiness and its components were hypothesized to be positively related to stress and coping strategies. Demographics were hypothesized to be unrelated to stress, hardiness, and coping strategies. Both hardiness and coping strategies were hypothesized to be predictors of stress. Pearson correlation coefficients, multiple regression, and linear regression were used in data analysis. Stress was associated with specific coping strategies viz., confrontation, selfcontrolling, accepting responsibility, and escape-avoidance. High hardiness, particularly commitment and challenge, was associated with low levels of stress and with problemfocused coping strategies. By contrast, low hardiness was associated with high stress and use of emotion-focused strategies. Significant demographics, when compared to study variables, included age, experience, time with supervisors, number of direct reports, highest degrees obtained, and formal or informal higher education in management. Young nurse managers who were less experienced in nursing and management, and who had fewer direct reports, reported the highest stress levels among nurse managers. High hardiness, particularly commitment, was a strong predictor of low levels of stress; use of escape-avoidance was a significant predictor of ...

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 ...

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 ...

The Historical Development of the Texas Academy of Mathematics and Science 1987-1992

Date: May 1996
Creator: Stride, Cindy F. (Cindy Flanagan)
Description: This study is a historical analysis of the significant events that led to the creation and evolution of the Texas Academy of Mathematics and Science (TAMS), from 1987 through 1992, and a description of the key individuals contributing to the development of the program. Included is a historical review of early college entrance and acceleration practices in the American educational system. In addition, the development of residential programs for mathematically and scientifically precocious high school-aged youths is offered. On June 23, 1987, the Texas Academy of Mathematics and Science was established by the 70th Texas Legislature. Though fourth in a line of special programs created for mathematically and scientifically able high school-aged youths, the TAMS model significantly deviated from its predecessors. Only the accelerative TAMS model would offer a college curriculum taught by college faculty and the opportunity to concurrently complete the last two years of high school and the first two years of college. From the inception of the program in 1987 through 1992, changes would occur. From 1987 through the summer of 1988, the development of the curriculum, student life program, and admissions process took place. From 1988 through 1989 the inaugural class was introduced to the program, ...
