Differences in School Districts' Decision-Making Processes Before and After Tax Limitation Elections: A Case Study (open access)

Differences in School Districts' Decision-Making Processes Before and After Tax Limitation Elections: A Case Study

Using a case study approach, this investigation focused on the decision-making processes involved in developing budgets in two Texas school districts following a tax limitation, or rollback, election. Factors influencing the decision-making processes included the rollback election's outcome in each district, the participants, the perceptions participants held of themselves, the perceptions participants held of others in the district and community, the decisions made, and the factors influencing participants' decisions. Two Texas school districts were selected as subjects of this study which used qualitative data collection methods. In one school district, the rollback election passed. In the other, it failed. Data collection included observations of school board meetings and budget workshops. Structured interviews of school board members and administrators, pro- and antirollback proponents, and newspaper editors were conducted. Questions focused on the budgetary decision-making processes before and after the rollback elections. They also solicited information fromsubjects regarding rollback elections, the factors precipitating the rollback elections and the impact of the rollback election campaign upon each school district. Document analyses were triangulated with the observations and interviews to identify the factors influencing the budgetary decision-making process. Following the rollback elections, school officials in both districts adopted a conservative approach to budgetary decision-making. …

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts (open access)

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts

This study was conducted to analyze the effect of implementation of Texas House Bill 72 on budgets of selected Texas public school districts and to ascertain educational benefits to students derived from implementation of the bill as perceived by superintendents. Questionnaires were sent to superintendents of the Region 10 Education Service Center to determine perceived educational benefits to students. A demographic data sheet provided information for classifying respondents by educational experience, superintendent experience, and district enrollment classifications. Sixty-two districts responded. Official public school budget data for each district were analyzed for fiscal years 1983 through 1986 as were data from the questionnaire. Overall statistical information was gleaned through CONDESCRIPTIVE. Mean total expenditures, mean total tax rate, and state fiscal aid data were compiled, tabulated, and reported for each enrollment classification and entire sample. In addition, a t-test between the difference of two independent means at a probability level of .05 was applied. The two independent means were the averages of data for the two years prior to and after implementation of the law for expenditures, tax rates, and state fiscal contributions. Data comparing local and state expenditures were compiled, tabulated, and reported for each group to compare local and state …

Development of Cooperative Education at the University of North Texas, 1976-1988 (open access)

Development of Cooperative Education at the University of North Texas, 1976-1988

The main purpose of the study is to describe the developmental story of one of the larger university cooperative education programs in the United States to provide the evidence of outcomes and to utilize selected elements of the program in other colleges and universities. The study utilizes historical methodology with a descriptive approach to investigate and analyze the program's establishment, its development of staffing, organization, students, employers, funding, and its evaluation by using primary and secondary sources, annual reports, federal grant request proposals, evaluation reports, and the on-campus newspaper. The information for this study was also gathered through personal interviews with previous and present staff members of the program. The study shows that the program was established in the dean of students' office, but in order to get more support from the faculty, the program was moved to the academic affairs office. As a result of the academic support by the faculty, the program expanded. The findings show that the federal grant, Title VIII, contributed significantly to the initiation and growth of the program. The investigator observes that the director's leadership and the staff members' commitment to the program were two of the most important factors in the continued growth …

Performance Evaluation of Community College Management Instructors Using Student Achievement as the Criterion (open access)

Performance Evaluation of Community College Management Instructors Using Student Achievement as the Criterion

This study concerns the relationship between student evaluation of instruction and student achievement in the field of management at the community college level. Purposes of the study were to determine the subjective student evaluation of instructor performance in introductory classes of management, student achievement in the class upon completion of the course, and the relationship between the student evaluation of instructor performance and student achievement in knowledge of the course. The population studied was all 10 sections of the Principles of Management course taught by 8 instructors at Del Mar College in Corpus Christi, Texas during the fall semester of 1988. A pretest-posttest design was used to determine student achievement scores. The College Board provided sufficient copies of two versions of the College Level Examination Program (CLEP) tests for Introduction to Management for the pretest and posttest. A special statistical technique using multiple regression was used to calculate an achievement score for each student that was adjusted for entry level knowledge. Student evaluations of instructor performance were paired with the achievement scores and grades students received from the instructor. Additional confidential demographic data was obtained about the students and the instructors. Major findings of the study concluded there is no …

A State-Wide Survey on the Utilization of Instructional Technology by Public School Districts in Texas (open access)

A State-Wide Survey on the Utilization of Instructional Technology by Public School Districts in Texas

Effective utilization of instructional technology can provide a valuable method for the delivery of a school program, and enable a teacher to individualize according to student needs. Implementation of such a program is costly and requires careful planning and adequate staff development for school personnel. This study examined the degree of commitment by Texas school districts to the use of the latest technologies in their efforts to revolutionize education. Quantitative data were collected by using a survey that included five informational areas: (1) school district background, (2) funding for budget, (3) staff, (4) technology hardware, and (5) staff development. The study included 137 school districts representing the 5 University Interscholastic League (UIL) classifications (A through AAAAA). The survey was mailed to the school superintendents requesting that the persons most familiar with instructional technology be responsible for completing the questionnaires. Analysis of data examined the relationship between UIL classification and the amount of money expended on instructional technology. Correlation coefficients were determined between teachers receiving training in the use of technology and total personnel assigned to technology positions. Coefficients were calculated between a district providing a plan fortechnology and employment of a coordinator for instructional technology. Significance was established at the …

The Presidency of William M. Pearce, Jr.: A History of Texas Wesleyan College From 1968 to 1978 (open access)

The Presidency of William M. Pearce, Jr.: A History of Texas Wesleyan College From 1968 to 1978

For almost two hundred years, liberal arts colleges dominated the American system of higher education. The Wesleyan movement into education was a missionary movement to provide an education to those denied this privilege by the class prejudices of the eighteenth century. Founded by the Methodist Episcopal Church, South, Texas Wesleyan University (originally known as Polytechnic College) began in 1891 with 11 faculty members and 173 students. It has survived despite the hardships of The Depression, economic adversities, and a severe financial crisis in the 1980s. Today with 73 faculty and 1,550 students, Texas Wesleyan remains committed to its original mission that the goal of education is the development of each student to his or her greatest potential. William M. Pearce, born in the woman's dormitory of Seth Ward College in Plainview, Texas, resigned his position as executive vice-president of Texas Technological University to become the thirteenth president of Texas Wesleyan College in June 1968. Upon assuming office, Pearce realized the need to concentrate his efforts on those things in need of repair and improvement. There was no faculty organization, no tenure, no formal budget process, and Texas Wesleyan was lacking many other standards usually found in institutions of higher education. …

An Investigation of Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls (open access)

An Investigation of Selected Female Singing- and Speaking-Voice Characteristics Through Comparison of a Group of Pre-Menarcheal Girls to a Group of Post-Menarcheal Girls

The purpose of this study was to compare the speaking fundamental frequency, physiological vocal range, singing voice quality, and self-perceptions of the singing and speaking voice between two groups of girls ages 11 through 15 years, who were pre-menarcheal by 6 months and post-menarcheal by 10 months or more. Subjects were volunteers who attended a North Texas public school system. Each subject was examined by an otolaryngologist. Age, height, weight, a hearing screening, and information on music classes and/or private music lessons were obtained. The speaking fundamental frequency measure was obtained by having each subject speak for 30 seconds on a subject of choice and read a passage of approximately 100 syllables. The vocal range measure was obtained by having each subject begin at an arbitrary pitch and sing mah and moo up the scale as high as possible and mah and moo down the scale as low as possible. These four measures were repeated with the researcher giving visual gestures. For singing-voice quality, each subject sang "America" in the key of her choice and again in the key of F major. Each subjects singing voice was rated according to breathiness. Data regarding self-perceptions of the singing and speaking voice …

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II (open access)

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one …

A Study Concerning the Use of Microcomputers for Word Processing in College Freshman Composition at a Community College (open access)

A Study Concerning the Use of Microcomputers for Word Processing in College Freshman Composition at a Community College

The purpose of this study was to determine the effect of using word processing and proofreading software in freshman composition at a community college. This study used pretest and posttest measures to determine if significant differences in the improvement of composition skills occurred between students in a composition class that did not use microcomputers and students in a composition class that did use microcomputers. Objective tests and writing samples were used as measurements. The population for the study consisted of students enrolled in freshman composition classes at a two year community college. Students self-selected enrollment in each class. Three hundred students who completed the pretest and posttest measures and completed the course were included in the study. There was no significant difference found in the improvement of writing skills between the two groups as measured by the objective test or the writing samples. There was a significant difference found in the withdrawal rate of students from the classes. The computer class had a significantly higher withdrawal rate than the non-computer class.

Organochlorine Pesticides and Heavy Metals in Fish From the Trinity River, Texas (open access)

Organochlorine Pesticides and Heavy Metals in Fish From the Trinity River, Texas

The Trinity River passes through the Dallas-Fort Worth metroplex receiving point and non-point source contaminant loadings. Lepomis spp. were collected at twelve sampling locations in the Trinity River in August 1987 and September 1988 and analyzed for organochlorine pesticides and heavy metals. Results from the study were compared to existing U.S. FDA action and tolerance levels, LC50s, and historical data. Various longitudinal trends and some concentration patterns were observed. Continual study of pesticide and metal body burdens in fish allow testing for trends, and thereby, lead to a better understanding of the distribution of contaminants in the Trinity River.

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties (open access)

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

An Investigation of Mexican Gravesites in Nuevo Laredo, Mexico and Laredo, Texas (open access)

An Investigation of Mexican Gravesites in Nuevo Laredo, Mexico and Laredo, Texas

My work already shared some of the characteristics of the gravesites that I proposed to study. They were similar in that they both attempted to integrate sacred and profane imagery. Both called attention to personal events and related these events to a larger scheme. Finally, both were involved with the creation of objects of veneration according to personal edicts, but in relation to already established mythologies. I proposed to create a body of work based on the information gathered from the investigation of three predominantly Mexican graveyards-- one in Nuevo Laredo, Mexico, and two outside of Laredo, Texas.
