Latent Transition Analysis of Pre-service Teachers' Efficacy in Mathematics and Science

Latent Transition Analysis of Pre-service Teachers' Efficacy in Mathematics and Science

Date: December 2009
Creator: Ward, Elizabeth Kennedy
Description: This study modeled changes in pre-service teacher efficacy in mathematics and science over the course of the final year of teacher preparation using latent transition analysis (LTA), a longitudinal form of analysis that builds on two modeling traditions (latent class analysis (LCA) and auto-regressive modeling). Data were collected using the STEBI-B, MTEBI-r, and the ABNTMS instruments. The findings suggest that LTA is a viable technique for use in teacher efficacy research. Teacher efficacy is modeled as a construct with two dimensions: personal teaching efficacy (PTE) and outcome expectancy (OE). Findings suggest that the mathematics and science teaching efficacy (PTE) of pre-service teachers is a multi-class phenomena. The analyses revealed a four-class model of PTE at the beginning and end of the final year of teacher training. Results indicate that when pre-service teachers transition between classes, they tend to move from a lower efficacy class into a higher efficacy class. In addition, the findings suggest that time-varying variables (attitudes and beliefs) and time-invariant variables (previous coursework, previous experiences, and teacher perceptions) are statistically significant predictors of efficacy class membership. Further, analyses suggest that the measures used to assess outcome expectancy are not suitable for LCA and LTA procedures.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Access: Use of this item is restricted to the UNT Community.
Date: May 2010
Creator: Runyon, Lisa
Description: Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

Metro Environmental: The impact of training HVAC technicians using the SightPros-VirTechs system for remote, wireless, Internet video assistance.

Metro Environmental: The impact of training HVAC technicians using the SightPros-VirTechs system for remote, wireless, Internet video assistance.

Date: May 2008
Creator: Daily, Ellen Wilmoth Matthews
Description: This qualitative study explored the overall impact of training HVAC technicians using the SightPros-VirTechs system for remote, wireless, internet video assistance at a small HVAC company, Metro Environmental. John Thomason, the president/co-owner developed a website and a new SightPros communication tool that allows wireless, one-on-one, just-in-time, high-quality, video-monitored instructions between an expert at one site and a technician at another site. Metro Environmental successfully used the SightPros-VirTechs system to train a new apprentice remotely. The apprentice and expert changed their normal and routine physical activities because the expert worked remotely and the apprentice worked on-site. Within just a few months, the apprentice proved competent enough to go to customer accounts without more experienced technicians nearby. The technicians express excitement about the SightPros communication tool as a way to contact remote experts whenever needed. The customer and business contacts also give good reviews and suggest other benefits. The expert permanently captures the communications so the company can use the saved video for many applications, especially training. The dissertation provides a list of recommendations to trainers/educators for similar applications.

Cyberbullying: Responses of Adolescents and Parents toward Digital Aggression

Cyberbullying: Responses of Adolescents and Parents toward Digital Aggression

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Wong-Lo, Mickie
Description: Cyberbullying is a category of bullying that occurs in the digital realm which affects our students at astonishing rates. Unlike traditional bullying, where displays of aggression may be evident to bystanders, the ramification of cyberbullying occurs through unconventional ways (e.g., text messaging; online weblogs; video sharing), which results in many cases being camouflaged by the advancement in technology. Nonetheless, the effects of this digital form of peer aggression can be as detrimental as face-to-face bullying. The characteristics of cyberbullying and its influences on adolescents and parents of adolescents were examined. The data accrued is based on an anonymous survey through one of the following methods: (a) paper-pencil survey for adolescent group with 37-question items on the adolescent questionnaire and (b) web-based survey for the parent group with 22-question items on the parent questionnaire. Each survey was systematically coded according to the participating group and assigned code numbers (i.e., 1 represents adolescent group and 2 represents parent group) was provided to ensure confidentiality of the study. Survey examined individual variables among the two target groups: (a) adolescents between 13 and 17 years of age and (b) parents of adolescents between 13 and 17 years of age. Specifically, individual variables examined include ...

Constructing transformative experiences through problem posing in a high school English research project.

Constructing transformative experiences through problem posing in a high school English research project.

Date: May 2009
Creator: Revelle, Carol L.
Description: This dissertation chronicles my search to engage high school English students in inquiry as part of a formal research process. The perspective of critical literacy theory is used to describe the four phases of the problem posing process in shaping student research and action. Grounded in Freire's approach and consistent with Dewey and others who advocate inquiry, action and relevance, Wink's process is built into the instructional plan described in this study. Because of the real-life context of the classroom and the complex social phenomena being considered, a case study methodology was utilized in which multiple sources of data converged to develop the themes. Data sources included the work and artifacts of ten students in a tenth grade English class during the spring semester of 2008. The analysis focuses on the supports, the constraints and the impact of problem posing on the high school research assignment. The analysis, findings, and conclusions contribute to the literature in three areas: audience, reflection and grading.

Characteristics of preservice teachers learning parent involvement practices.

Characteristics of preservice teachers learning parent involvement practices.

Date: August 2008
Creator: Trotti, Judy
Description: Numerous models of IS success and technology acceptance their extensions have been proposed and applied in empirical. This study continues this tradition and extends the body of knowledge on the topic of IS success by developing a more comprehensive model for measuring IS success and technology acceptance within a government organization. The proposed model builds upon three established IS success and technology acceptance frameworks namely the DeLone and McLean (2003), Venkatesh et al.'s (2003) unified theory of acceptance and use of technology (UTAUT), and Wixom and Todd (2005). The findings from this study provide not only a comprehensive IS success assessment model but also insights into whether and how IS success models are influenced by application variables as applied within a government organization. Exploratory factor analysis and confirmatory factor analysis were performed for instrument refinement and validity test of the existing and proposed models. Using data from employees of a local government municipal, the comprehensive model explained 32 percent variance. Four of the hypothesis were fully supported five were not supported, and four were partially supported. In addition, the results suggest that behavioral intention may not be the best predictor of technology acceptance in a mandatory environment.

Megatrends in Higher Education

Megatrends in Higher Education

Date: August 2008
Creator: Smith, Shannon Tucker
Description: Utilizing the theory of John Naisbitt's 1982 Megatrends, this study identifies eight trends for the future of higher education using content analysis of generalized print media reports for three bell-wether states. For the period of 2001-2005, generalized reporting for three newspapers, the Los Angeles Times from Los Angeles, CA, the Miami Herald from Miami, FL, and the Denver Post from Denver, CO, included over four thousand articles and covered 21 primary topics and over 200 secondary topics. Eight trends emerge from the content analysis. Trend 1, from the ivory tower to the public domain, identifies increasingly critical public scrutiny of higher education standards and curricula. Fight or flight, Trend 2, reveals more consistent no-tolerance policies for student behavior. Trend 3, scholar to celebrity, reveals an increasingly public role for university presidents. Academic freedom to academic flexibility, Trend 4, identifies a tightening of academic freedom policies for university staff and faculty. Trend 5, pay now, learn later, focuses on increased popularity of pre-paid and tax free plans for saving college tuition. Fraternity party to fraternity accountability, Trend 6, identifies increased scrutiny of Greek organizations and Greek life within the university environment. Trend 7, tenure to temporary, reflects the growing trend of ...

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 ...

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.
