Factors Affecting Academic Interest and Self Perception of Adolescent Hispanic Females

Factors Affecting Academic Interest and Self Perception of Adolescent Hispanic Females

Date: August 2007
Creator: Abel, Karen
Description: This investigation identifies deterrents to the educational, social, and cultural success of Latina adolescent females. Across the nation, and especially in states such as Texas and California, the Hispanic population is fast becoming the largest minority in society. Because the adolescent Hispanic population within the United States today will comprise much of America's future economic and social base, identifying and addressing educational, cultural, and social deterrents to their success becomes important not only for personal well-being, but for the well-being of future society as a whole. A second purpose was that of determining the efficacy of group-centered psychoeducational therapy in improving self-esteem and decreasing anxiety and depression symptoms in adolescent female Hispanic high school students. The experimental groups consisted of one group of seven female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. and a second group of five female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. The control group consisted of fourteen female Hispanic students who received no treatments. The Beck Depression Inventory was used to measure pre and post test levels of depression, the Beck Anxiety Inventory ...

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.

Attitudes toward Research and Teaching:  Differences Between Faculty and Administrators at Three Saudi Arabian Universities

Attitudes toward Research and Teaching: Differences Between Faculty and Administrators at Three Saudi Arabian Universities

Access: Use of this item is restricted to the UNT Community.
Date: May 2000
Creator: Alsouhibani, Mohammed A.
Description: This study is an investigation of the perceived attitudinal differences between administrators and faculty toward research and teaching at three Saudi Arabian universities, King Saud University (KSU), King Fahd University of Petroleum and Minerals (KFUPM), and the Islamic University (IU). The researcher also investigated the effect of several variables, such as rank, university, and academic field on administrators and faculty members' attitudes toward teaching and research. Little Attention has been given to studies that examine the differences between faculty and administrators with regard to their attitudes toward the priorities of teaching and research in Saudi Arabian institutions. Also, little research has been conducted regarding the effects of rank and academic field on faculty attitudes in Saudi Arabian institutions. The author used a mail survey and collected 518 useable responses from a total of 710 questionnaires distributed. Factor analysis, MANCOVA, MANOVA, and ANOVA were the statistical methods employed in data analysis. Five attitudes were identified as a result of factor analysis: (a) attitudes toward teaching; (b) attitudes toward research; (c) mission; (d) promotion; and (e) interest. Results indicated that there was a significant difference between faculty and administrators regarding teaching and resea4rch. Administrators showed stronger attitudes toward teaching than faculty at ...

An experimental investigation on the effects of Web-based instruction / training on cognitive and psychomotor learning

An experimental investigation on the effects of Web-based instruction / training on cognitive and psychomotor learning

Date: August 2000
Creator: Alzafiri, Fayiz M.
Description: The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learnersÂ’ performances while soldering. The 2 x 2 factorial model with interaction ...

A comparison of five robust regression methods with ordinary least squares: relative efficiency, bias and test of the null hypothesis

A comparison of five robust regression methods with ordinary least squares: relative efficiency, bias and test of the null hypothesis

Access: Use of this item is restricted to the UNT Community.
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.

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 ...

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 ...

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 ...

An evaluation of student learning and engagement in a technology-enhanced algebra unit on slope

An evaluation of student learning and engagement in a technology-enhanced algebra unit on slope

Date: August 2000
Creator: Beck, Elaine K.
Description: The purpose of this study was to examine the effectiveness of a technology-enhanced unit on slope in algebra. The technology used in the study was the Topological Panorama Camera (Topocam). The research questions explored the learning and transfer of knowledge about slope and the engagement level of students during Topocam learning activities. The Topocam is a computer-controlled camera that moves on a modular track while it scans a scene through a vertical slit. Students can program the speed of the camera and frequency of pictures. They then witness the results of time and motion in the image created by the camera. Data for this study were collected from a pretest/posttest, as well as from observations of indicators of engaged learning. The research population consisted of 46 students from three classes of Algebra I students. Three classroom teachers each taught a unit on slope, while a fourth teacher conducted the activities with the Topocam for all the classes. The classroom activities focused on the concept of slope as a rate of change utilizing coordinate grids. The Topocam activities involved students in collaboratively making and testing predictions about slope. The findings of the study indicate that student learning did occur with this ...

The Relationship Between Classroom Climate and Student Achievement

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 ...
