Knowledge and attitudes of preservice teachers towards students who are gay, lesbian, bisexual, or transgendered.

Knowledge and attitudes of preservice teachers towards students who are gay, lesbian, bisexual, or transgendered.

Date: December 2003
Creator: Morgan, Daniel J.
Description: The study used a survey design to ascertain the levels of knowledge and attitudes of special education and non-special education preservice and inservice teachers towards students with different sexual orientations. The results of this study are based on 408 responses from preservice and inservice teachers enrolled at seven institutions of higher education within North Carolina, Virginia, and the District of Columbia offering teacher training programs in regular and/or special education. Two previously developed instruments were used to measure dependent variables in this study. Koch's modified version of The Knowledge about Homosexuality Questionnaire developep by Harris, Nightengale & Owen was used to measure the dependent variable of the preservice and inservice teacher's knowledge about homosexuality. Herek's Attitudes Toward Lesbians and Gay Men (ATLG) measured the dependent variable of attitudes towards homosexuals. The study found no significant differences reported mean scores for knowledge or attitude of homosexuality among the teacher groups surveyed: (a) special education preservice teachers, (b) non-special education preservice teachers, (c) special education inservice teachers, and (d) non-special education inservice teachers. Neither gender nor age were found to be factors in measures of knowledge or attitude of preservice or inservice teachers. Receiving prior instruction in serving the needs of GLBT ...

Ninth grade student success: An analysis of a credit recovery program.

Date: December 2003
Creator: Christian, Fredelyn Walters
Description: The purpose of the study was to determine the extent to which a credit recovery program improved the academic success for high school freshmen. For the purpose of this study, academic success was defined as whether or not the student advanced from 9th to 10th grade. A total of 255 students from two junior high schools and one comprehensive high school were included in the study. Independent variables included program, gender, ethnicity, socioeconomic status, TAKS Reading/Language Arts results, and TAKS Mathematics results. A review of related literature provided background information regarding the issues surrounding high school freshmen, dropouts, grade retention, and effective intervention programs. This quantitative study utilized descriptive statistics and logistic regression to analyze the relationship between the independent variables and student success as measured by whether or not the student advanced from ninth to tenth grade. In addition, the study examined the odds of success if participating in the credit recovery program. Sources of data included Incomplete and Failure Listing, Ninth Grade Advisor Listing, Tenth Grade Advisory Listing, and the Student Roster-Fall Collection. The Ninth Grade Success Initiative Program Evaluation for Cycles 6, 7, and 9 provided the individual student results of participation in the program. Levels of ...

Presidents' Leadership Behaviors Associated with Followers' Job Satisfaction, Motivation Toward Extra Effort, and Presidential Effecitveness at Evangelical Colleges and Universities

Presidents' Leadership Behaviors Associated with Followers' Job Satisfaction, Motivation Toward Extra Effort, and Presidential Effecitveness at Evangelical Colleges and Universities

Date: December 2003
Creator: Webb, Kerry S.
Description: Transformational leaders have tendencies that include: 1) projecting confidence and optimism about goals and followers' ability, 2) providing a clear vision, 3) encouraging creativity through empowerment and rewarding experimentation, 4) setting high expectations and creating a supportive environment, and 5) establishing personal relationships with followers. Transactional leadership as a process in which leaders and followers decide on goals and how to achieve them through a mutual exchange. The leader provides followers with resources, rewards, and punishment in order to achieve motivation, productivity, and effective task accomplishment. Laissez-faire leadership is the process of letting followers work without direction or guidance from the leader. The laissez-faire leader avoids providing direction and support, shows a lack of active involvement in follower activity, and abdicates responsibilities by maintaining a line of separation between the leader and the followers. The primary purpose of this study was to investigate the assumption that a combination of transformational and transactional leadership factors is more predictive of greater followers' job satisfaction, motivation toward extra effort, and perceived presidential effectiveness than either leadership style alone. The study investigated perceptions of the degree to which transformational leadership, transactional leadership, and laissez-faire leadership were practiced by presidents of member colleges and universities ...

A Comparison of IRT and Rasch Procedures in a Mixed-Item Format Test

A Comparison of IRT and Rasch Procedures in a Mixed-Item Format Test

Date: August 2003
Creator: Kinsey, Tari L.
Description: This study investigated the effects of test length (10, 20 and 30 items), scoring schema (proportion of dichotomous ad polytomous scoring) and item analysis model (IRT and Rasch) on the ability estimates, test information levels and optimization criteria of mixed item format tests. Polytomous item responses to 30 items for 1000 examinees were simulated using the generalized partial-credit model and SAS software. Portions of the data were re-coded dichotomously over 11 structured proportions to create 33 sets of test responses including mixed item format tests. MULTILOG software was used to calculate the examinee ability estimates, standard errors, item and test information, reliability and fit indices. A comparison of IRT and Rasch item analysis procedures was made using SPSS software across ability estimates and standard errors of ability estimates using a 3 x 11 x 2 fixed factorial ANOVA. Effect sizes and power were reported for each procedure. Scheffe post hoc procedures were conducted on significant factos. Test information was analyzed and compared across the range of ability levels for all 66-design combinations. The results indicated that both test length and the proportion of items scored polytomously had a significant impact on the amount of test information produced by mixed item ...

Educators' Technology Level of Use and Methods for Learning Technology Integrations.

Date: August 2003
Creator: Griffin, Darlene Ann
Description: The purpose of this study was to describe technology learning methods that teachers attend and perceive as effective. The goal was to provide district personnel data that may be utilized when planning for more effective technology staff development. This study examined (1) the methods of learning instructional technology that are being utilized by teachers and administrators and (2) why these methods are being utilized in two Texas school districts. Data was collected from educators via an online survey consisting of demographics, technology training methods, level of technology use (CBAM 1 item), stages of adoption and technology level of use (LoTi, 50-item). Educators with different technology levels of use (high, low) differed on their perceptions and utilization of technology training methods.

The Effects of Premenstrual Syndrome Symptomatology on Marital Satisfaction

The Effects of Premenstrual Syndrome Symptomatology on Marital Satisfaction

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Rodgers, Glenda S.
Description: Many women reporting PMS symptoms state their symptoms affect their mood, social, and family functioning. This study attempted to provide clinicians with information to assist in psychotherapeutic intervention, by determining the effect PMS has on marital satisfaction. Nineteen female subjects reporting PMS symptoms and their partners completed the study. The Marital Satisfaction Inventory - Revised (MSI-R) and the Moos Menstrual Distress Questionnaire-Form T (MDQ-form T) were used to determine if the nineteen couples reported marital distress as a result of the women's cyclical premenstrual symptoms. The results of the study suggested that the women and their partners, report high levels of marital distress that is not reflective of the cyclical nature of the PMS symptomatology. Scores on the MSI-R for the subjects and their partners indicated the couples perceived level of distress in the t-50 to t-70 range on scales 3-8 is consistent throughout the menstrual cycle. The couples reported higher levels of marital distress than would be the expected norm, suggesting that PMS may be a contributing factor to the level of distress they reported experiencing. This study did not include a control group, which would have provided a norm for couples who do not report PMS by which ...

Impact of Absent Father-Figures on Male Subjects and the Correlation to Juvenile Delinquency: Findings and Implications

Impact of Absent Father-Figures on Male Subjects and the Correlation to Juvenile Delinquency: Findings and Implications

Date: August 2003
Creator: Eastin, Jennifer Flood
Description: This study was predicated on the belief that a father brings something unique to the family, thus, making irreplaceable contributions to the life of a child. Fathers are unique in that they provide something different from mothers. They are irreplaceable because when they are absent, children are said to suffer emotionally, intellectually, socially, and behaviorally. The contributions of fathers to a child's well being cannot be fully replaced by better programming, ensuring child support programs, or even by well-intentioned mentoring programs. A review of literature relevant to delinquency and adolescent behavioral and academic success revealed that there may be a correlation between a male role-model and the teaching of self-control and socially appropriate behaviors. Indeed, much of what the large body of research pertaining to fatherhood reveals is that, compared to children raised in two-parent homes, children who grow up without their fathers have significantly worse outcomes, on average, on almost every measure of well being (Horn, 2002). In addition, an understanding of the factors that may influence delinquent behaviors, in particular within the family unit, can better equip parents and educators to support those who may be exhibiting the beginning signs of delinquent behavior. This study was designed to ...

Candidates' Perception of Training and Self-Efficacy in Traditional and Alternative Teacher Preparation Programs.

Candidates' Perception of Training and Self-Efficacy in Traditional and Alternative Teacher Preparation Programs.

Date: May 2003
Creator: Thompson, Tierney M.
Description: This research was encouraged by the tremendous demand for teachers. Two million new teachers will be needed in the United States over the next decade. The teacher shortage has school administration, school boards, education agencies, and institutions of higher education investigating how to train and retain more teachers. Alternative certification programs have been developed to address the teacher shortage. This study examined the effectiveness of traditionally and alternatively certified teachers in two separate programs with regard to their self-efficacy, perception of their training, and their ExCET scores. Traditional candidates (10) and alternative candidates (74) were examined using survey research. According to this data on self-efficacy, perception of training, and ExCET passing rates, there is no significant difference between those teachers who receive traditional training and those who are trained in alternative certification programs.

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.

Date: May 2003
Creator: Andrews, Charles G.
Description: The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests ...

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities

Date: May 2003
Creator: Alexander, Erika D.
Description: The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Pierce, Laura Boehl
Description: Many children in the United States cannot read on level by fourth grade. Traditionally, teachers have delayed reading instruction until first grade. However, involving children sooner in literary activities may provide skills needed to enable them to read on grade level. The purpose for this study was to determine the extent to which daily writing in kindergarten influences the development of invented spelling and learning to read. Five teachers modeled writing with 78 kindergarten children who wrote every day or almost every day for 20 weeks. There were 51 children in an experimental group, and 27 in a control group who were given a pretest and a posttest using the Observation Study (Clay, 1993). Results from a mixed model ANOVA indicated a significant difference between the control group and the experimental group on the Dictation Task F (1, 76) = 11.76, P≤ .001 and the Writing Test F (1, 76) = 4.33, P≤ .01. Results from a z-Test of dependent proportions indicated there were significant differences in the reading levels of the control group from the pretest to the posttest (z = 7.51, P ≥ .05) because (z = 7.51, Zcv = 1.96). The experimental group results from pretest to ...

Student preferences in screen design factors for Internet delivered college courses.

Student preferences in screen design factors for Internet delivered college courses.

Date: May 2003
Creator: Pineau, Joseph Roy
Description: Colleges and universities throughout the world are offering many of their courses via the Internet. Some institutions offer entire degrees online. This has ushered in a renewed interest in the debate on the effectiveness of non-traditional course delivery method. Numerous educational research studies have been conducted in an attempt to quantify that effectiveness. In any form of experimental research, control of variables is paramount. The rich multimedia capabilities of the World Wide Web give educators a wide variety of delivery media. However, with the exception of advice from artisans on design factors of the media, little research has been conducted with regard to the aesthetics of Web page design as viewed by the student. This study was conducted in an effort to establish student preferences with regard to two factors of Web page design as they might be used on those Web pages, background color and typeface used for text. In addition, it contains an analysis of whether or not there is an interaction between the two factors. Use of the results of this study should prove beneficial to both educators and educational researchers in their future endeavors.

Computer Supported Collaboration: Is the Transfer of Cognitive Structures Mediated by Mode of Communication?

Computer Supported Collaboration: Is the Transfer of Cognitive Structures Mediated by Mode of Communication?

Date: May 2002
Creator: Bandy, Kenneth E.
Description: The objective of this study was to observe evidence of structural transfer among subjects in a group problem-solving activity and determine whether mode of collaborative technology or use of a priming agent affected the nature of transferred structures. Evidence for structural transfer is found in three theoretical perspectives: organizational ditransitive (linguistic) verb structures, adaptive structuration theory, and mental model transfer theory. Dependent variables included various grammatical structures and coefficients derived from pretest and posttest scores on David Kolb's Learning Styles Inventory, modified for the experiment. The combination of changes in grammatical frequencies and learning style may suggest that one or more media or the priming agent may affect structural transfer. Results indicate that groups using the GroupSystems™ collaborative technology produced less overall linguistic content than did subjects using a generic chat system, but employed more complex language as indicated by frequency of the organizational ditransitive verb structure. Also, subjects supplied with an organization chart (priming agent) during the group problem-solving session experienced greater change on the learning styles inventory than did those participating in the session without the chart. These findings suggest that mode of communication and use of priming agents may contribute positively or negatively to the transfer of ...

Mentoring the first-year superintendent in Texas public schools.

Mentoring the first-year superintendent in Texas public schools.

Date: May 2002
Creator: McNulty, Rock Edward
Description: This study determined what mentoring experiences first-year superintendents have had and what they need from a mentoring relationship. Structured interviews and field notes were used in this qualitative study focused on Texas first-year superintendents' perceived needs from mentors. Three patterns of mentoring relationships were found: 1) no mentor in the first year, 2) mentor-protégé relationship - those who developed mentoring relationships early in a career with a more senior person in the same school system, and 3) mentoring relationships of convenience - young relationships which developed outside the same system. Skills and knowledge areas novice superintendents identified as critical for mentor assistance were school finance, development of effective relationships with groups that have expectations of the superintendent while also improving student achievement, and working within the politics of the position. Mentor characteristics novice superintendents considered necessary for a positive effect on job success include: trustworthiness, confidentiality, empathy, encouraging, active listening, and integrity. An attitude in which the mentor problem solved with the protégé, and did not give an immediate solution was displayed. Mentors actively and frequently initiated contact. Ideas were freely exchanged, giving the protégé undivided attention while not making the protégé feel inferior. The effects that previous mentoring experiences ...

Date: May 2002
Creator: Cramer, Conita K. Markel
Description: The procedural survey on sexual harassment procedures sent to 300 Texas principals had a response rate of 48.3 %. The mean score on the procedural survey for all 300 principals was 69.30 %. Eighteen research questions were addressed in detail in Chapter 4. Only five showed a significant correlation or effect size. Question 5 asked if there was a correlation between gender and the mean score of the survey instrument regarding sexual harassment procedures. The mean score of women was significantly higher than men. Question 6 asked if there was a correlation between the number of students in a school and the mean score of the survey instrument regarding sexual harassment procedures. This revealed that a significant correlation appeared between principals who worked at larger schools. Question 10 asked if there was a correlation between the location of the school, whether rural, urban, or metroplex and the mean score of the survey instrument. Principals of urban and metroplex schools scored significantly higher. Question 13 asked if there was a correlation between the hours of sexual harassment training attended in the last year and the mean score of the survey instrument regarding sexual harassment procedures. The results of this analysis revealed ...

Date: December 2001
Creator: Harris, Ellen L.
Description: The purpose of this study was to identify and analyze sales people's perceptions of performance appraisal criteria in a telecommunications corporation. The study was prompted by the perceived disillusionment of the sales people with the current performance appraisal criteria. The perceptions of 67 sales people were assessed using a questionnaire developed by the researcher. One-way analysis of variance procedures (ANOVA) were used to determine if there were statistically significant differences in premise and telemarketing sales people's perceptions of performance appraisal criteria. Findings indicated that there were no statistically significant difference in premise and telemarketing sales people's perceptions of the 38 performance appraisal criteria statements. Findings did not indicate a statistically significant difference in premise and telemarketing sales people's perceptions of the performance criteria statements, the attitude or satisfaction statements, and the peripheral issue statements. Based on this study, the sales people appear to have clear perceptions of the performance appraisal criteria.

The Impact of Poverty on Comparable Improvement Ranking for Elementary Campuses in Texas

The Impact of Poverty on Comparable Improvement Ranking for Elementary Campuses in Texas

Date: December 2001
Creator: Holland, Vicki Gay
Description: The problem was to determine how comparable is comparable improvement for campuses in Texas. An alternative strategy for determining comparable improvement was developed using 2000 comparable improvement data provided by the Texas Education Agency for 2,403 elementary campuses. Comparable improvement is a measure that shows how student performance has changed from one year to the next and then compares that growth to 40 schools that are demographically most similar to the target school. Instead of using the most dominant characteristic as in the current process, the percent of students in poverty was the initial sorting characteristic. The impact of sorting by poverty was reviewed in four areas: 1.) the impact on quartile placement, 2.) the TLI average growth for the comparison group, 3.) the award eligibility, and 4.) the changes in comparison group composition. No practical significant difference was found for research questions 1 and 3, however, a practical significant difference was found in group average TLI growth for math and in the comparison group composition. Overall, the alternative process had the greatest impact on campuses with 40-80% poverty. Three possible factors may have influenced the results. First, the middle poverty campuses had the most change in comparison group as ...

The Relationship Between Classroom Climate and Student Achievement

Date: December 2001
Creator: Bennett, Jan
Description: The purpose of this study was to determine the relationship between sixth grade students' academic achievement levels in math and their perceptions of school climate. Student characteristics of socioeconomic status and gender were used to identify groups for the purpose of data analysis. Data was gathered using the five independent variables of the My Class Inventory (satisfaction, friction, competitiveness, difficulty, and cohesiveness) and the dependent variable of the Stanford Achievement Total Math scores. The results of the data collection were tested using a Pearson product-moment analysis and a backward multiple regression analysis. A univariate analysis of variance was also used to compare the five independent variables of the My Class Inventory as well as to compare socioeconomic status and gender with the Stanford Achievement Total Math scores. The schools selected for this study were from a city in Texas with a population of approximately 100,000. The sample consisted of 262 sixth grade mathematics students. The findings of this study are as follows: (a) The Pearson product-moment correlation analysis revealed little, if any, correlation for any of the five subscale predictor variables; (b) the multiple regression analysis revealed that all five classroom climate indicators combined together could explain only 10.5% of ...

Description: The purpose of this study was to determine the level of burnout among student affairs professionals at the 52 U.S. member institutions of the Coalition of Urban and Metropolitan Universities. Packets containing the Maslach Burnout Inventory (MBI), the Moos Work Environment Scale (WES), and a demographic survey were mailed to 371 senior student affairs administrators at the member institutions, with a completed response rate of 58.22%. The senior student affairs administrators surveyed included the chief student affairs officers and the professional staff who reported to them. The research design employed t-tests, analyses of variance, and Pearson's Product Moment correlations. The scores obtained from the MBI and WES subscales were compared overall and along 9 independent variablestitle of position, size of institution, appointment, salary, years in current position, years in profession, age, gender, and highest degree attained. Average levels of burnout were found on each of the MBI subscores. Contrary to earlier studies, women did not suffer from statistically significant higher levels of burnout than men, and burnout levels decreased with age and years in the profession for both sexes. Lower scores on the MBI depersonalization subscale were found in employees in mid-career and in professionals from smaller schools. Emotional exhaustion ...

Date: August 2001
Creator: Anderson, Cynthia, 1962-
Description: A Monte Carlo simulation was used to generate data for a comparison of five robust regression estimation methods with ordinary least squares (OLS) under 36 different outlier data configurations. Two of the robust estimators, Least Absolute Value (LAV) estimation and MM estimation, are commercially available. Three authormodified variations on MM were also included (MM1, MM2, and MM3). Design parameters that were varied include sample size (n=60 and n=180), number of independent predictor variables (2, 3 and 6), outlier density (0%, 5% and 15%) and outlier location (2x,2y s, 8x8y s, 4x,8y s and 8x,4y s). Criteria on which the regression methods were measured are relative efficiency, bias and a test of the null hypothesis. Results indicated that MM2 was the best performing robust estimator on relative efficiency. The best performing estimator on bias was MM1. The best performing regression method on the test of the null hypothesis was MM2. Overall, the MM-type robust regression methods outperformed OLS and LAV on relative efficiency, bias, and the test of the null hypothesis.

Physical activity and its association with selected dietary behaviors

Date: August 2001
Creator: Cartwright, Amanda R.
Description: This study examined the association between level of physical activity and changes in dietary behaviors of 3,945 employees after a 10-week work-site physical activity program. Fifty-seven percent of the participants met the CDC/ACSM standard for physical activity sufficient for a health benefit. Physical activity was not significantly related to increased fruit and vegetable consumption, decreased dietary fat and calorie intake, and participants acquiring new nutrition skills. Physical activity was negatively associated with increased food label awareness. Participants who exercised sufficient for a health benefit were less likely to increase their food label awareness. Physical activity and dietary behaviors are generally not associated. Interventions to improve these behaviors should be behavior-specific.

A Study Of Correlations Between Learning Styles Of Students And Their Mathematics Scores On The Texas Assessment of Academic Skills Test

Date: August 2001
Creator: Kopsovich, Rosalind D.
Description: The problem of this study was to determine whether learning styles of students affect their math achievement scores on the Texas Assessment of Academic Skills Test. The research questions addressed relevant to this study were: 1. Is there a positive correlation between students' learning styles and their achievement test scores in mathematics? 2. Is there a positive correlation between specific sub group's (as deemed by the state of Texas) and gender's learning styles and their achievement test scores in mathematics? The Pearson Product Moment Correlation coefficient and the Point-biserial correlation analysis was applied to the data collected from 500 fifth grade students attending a North Texas Intermediate school. The significance level was established at the .05 level. Part of the data was the student's responses to the Learning Style Inventory by Dunn, Dunn and Price. The findings established that the learning style preferences of all students in the area of persistence significantly impacted their math achievement scores. Gender and ethnicity were mitigating factors in the findings. These learning style preferences significantly impacted achievement in the following ways: * Caucasian students' preference of a high level of persistence in completing a difficult task. * Hispanic students' preference for a warm learning ...
