A method was developed for extending a fine-scaled forest gap model to a watershed-scaled landscape, using the Eastern Cross Timbers ecoregion as a case study for the method. A topographic wetness index calculated from digital elevation data was used as a measure of hydrologic across the modeled landscape, and the gap model modified to have with a topographically-based hydrologic input parameter. The model was parameterized by terrain type units that were defined using combinations of USDA soil series and classes of the topographic wetness index. A number of issues regarding the sources, grid resolutions, and processing methods of the digital elevation data are addressed in this application of the topographic wetness index. Three different grid sizes, 5, 10, and 29 meter, from both LiDAR-derived and contour-derived elevation grids were used, and the grids were processed using both single-directional flow algorithm and bi-directional flow algorithm. The result of these different grids were compared and analyzed in context of their application in defining terrain types for the forest gap model. Refinements were made in the timescale of gap model’s weather model, converting it into a daily weather generator, in order to incorporate the effects of the new topographic/hydrologic input parameter. The precipitation …

In a 3-year timeframe, nearly 800 student negligence suits were filed, and most involved some claim of personal injury. Despite heightened public attention of negligence lawsuits against school districts and their employees, an empirical study of court decisions revealed that the volume of litigation against school districts remained steady from 1990 to 2005, the majority of cases were ruled in favor of the school district employees, and government and official immunity were most often the basis for these rulings. Researchers have concluded that immunity laws are strong in the United States, although they vary by state in their application. However, a primary recommendation was that, because of the misconception of a lack of immunity for public school employees, a comprehensive study on governmental and official immunity is needed. This dissertation employed legal research, analysis, and methodology to engage in a comprehensive investigation of teacher immunity in the four southern states of Texas, Oklahoma, Mississippi, and New Mexico. Of central concern to this dissertation was the Tort Claims Act of 1978 from the State of New Mexico. The Tort Claims Act is the vehicle by which immunity is granted to public school employees. Court findings over the last 35 years point …

The effect of an interdisciplinary algebra/science course on students' critical thinking skills was examined. A traditional college algebra course was used as a comparison group. The students in the sample enrolled in college algebra and then half were randomly placed into the interdisciplinary course. A quasi-experimental pretest-posttest comparison group design was used. The Watson-Glaser Critical Thinking Appraisal was used to measure the students' critical thinking skills. This instrument consists of an overall critical thinking score as well as five subscores in the areas of Inference, Recognition of Assumptions, Deduction, Interpretation and Evaluation of Arguments. It was found that the students in the interdisciplinary course made greater gains in the overall critical thinking score as well as in four of the five subscores. However, the differences in the gains made in the two courses were not statistically significant. Disregarding course, other factors that were found to be closely related to critical thinking were Composite ACT, grade received in the course, Math ACT and grade point average. It was also found that students whose majors were in the Schools of Arts and Letters or Science and Technology scored higher on critical thinking than students whose majors were in the Schools of Business …

The purpose of the study was to describe the use of nonfiction/informational trade books within a literature-based elementary classroom by students and the teacher. Using a qualitative ethnographic approach, the researcher became a participant observer in a third grade classroom during a two and one-half week thematic unit about the westward movement. Data were collected from field notes, audiotapes of class discussions and informal interviews, documents of students' work, photographs, daily observer comment summaries, and memos. These data were coded, analyzed for recurring patterns, and grouped together, resulting in grounded theory.

The purpose of this study was to investigate the self-perceptions certified public high school teachers in the fine arts have toward their roles as artist and instructional staff member.

This study identified the admissions criteria for selected doctoral programs in vocational-technical education in Oklahoma and Texas and investigated the relationship of these criteria to success in the doctoral programs. Success in the doctoral programs was identified in terms of cumulative doctoral grade point average. Data were obtained through a questionnaire designed to ©licit both general information concerning admissions criteria for vocational-technical doctoral programs at the selected institutions and to collect specific information on a random sample of twenty doctoral candidates from each of the four selected institutions. Factors considered included birthdates, gender, scores on admissions tests, grade point average in the masters program, the year the latest masters was completed, number of colleges attended, and cumulative doctoral grade point average. A statistical analysis using nine separate one-way analyses of variance determined that four of the nine factors considered proved to be statistically significant at the .05 level or better when correlated with the criterion variable (cumulative doctoral grade point average). Those factors were gender, Graduate Record Examination verbal and composite scores, and masters grade point average. The results of the study basically parallel findings of research concerning admissions criteria and success in graduate programs in other areas. Additional research …

The purpose of this study was to investigate the impact of basic communication fidelity (BCF) upon the perceptions of national observers toward national and international communicators across a variety of group interaction variables. Research is presented which indicates that (1) international students are typically perceived less favorably than national students across a variety of interpersonal variables; (2) as BCF increases, more favorable ratings are attributed to communicators across interpersonal variables; and (3) increased BCF may be able to mitigate the less favorable impressions national observers attribute to international communicators.

This study examined the attitudes of undergraduate college students toward marriage and family life. The students in the study lived in college residence halls located in the states of Arkansas, Louisiana, Oklahoma, and Texas in the southwestern portion of the United States. A survey instrument consisting of fifty-eight attitude statements and six demographic items was used to gather information for the study. All of the fifty-eight attitude statements were listed in the following ten cluster areas for easier accessibility: cohabitation and premarital sexual relations, marriage and divorce, childhood and child rearing, division of household labor and professional employment, marital and extramarital sexual relations, privacy rights and social needs, religious needs, communication expectations, parental relationships, and professional counseling services. The six demographic items included age, gender, ethnic background, year in school, parental status, and dating experience .

This study was an investigation of teaching strategies and student outcomes of the drug education program in five pilot schools in Oklahoma as these programs relate to the "ideal" program recommended by drug education experts. This study had a twofold purpose. The first was to determine the differences of the perceptions of students, teachers and administrator toward the drug education program in their own school. The second was to compare this perceived "actual" program with the "ideal" program as described by selected drug education experts. The study centers on five exploratory questions. With the completion of the five exploratory questions, it was concluded that the factors that are descriptive of the "ideal" and "actual" drug education programs can be identified from opinions of persons who have an interest in or responsibility for effective information concerning the drug scene.

The study examines the use of hypnotic audiotapes designed to affect study habits and attitudes. It is assumed that exposure to the hypnotic audiotapes will improve study habits and attitudes. It is further expected that exposure to the audiotapes will improve students' self-concepts and adjustment to college work, as well as reduce anxiety. Previous studies are cited which indicate that hypnosis has had a positive effect on learning. Hypnosis has been shown to be an effective means of changing specific behaviors.

The problem of this study was the development of a proposal for an industrial arts program for Langston University. Particular emphasis was placed upon curriculum changes, faculty improvement, and modification of physical facilities.

The problem with which this study is concerned is that of determining the relationship between curriculum offerings in industrial arts and the academic preparation of industrial arts and the academic preparation of industrial arts teachers in the public secondary schools of Oklahoma.

This study was designed to determine whether or not auditory discrimination could be improved in a group of third-grade students by the use of a tape-recorded program of auditory exercises. Of additional interest was the effect that the program of auditory exercises would have upon the work recognition skills and the spelling skills of the third-grade students involved.
