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.
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 ...

Texas Public School Principals' Application of Procedures in Identification and Prevention of Sexual Harassment
Access: Use of this item is restricted to the UNT Community.
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 ...

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.
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
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.

The Great Debate continued: Does daily writing in kindergarten lead to invented spelling and reading?
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.
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.

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. Specifically, educators with different technology levels of use differed in their perceptions of independent online help, and learning through trial and error technology training methods. Results from the study showed that educators tended to use the technology training method that they perceived as most effective. Educators tended to utilize learning by trial and error, peer support, and technology personnel support the most frequently for learning technology integration Educators' in the study had varying technology levels of use based on their ...
