Academic Qualification and Employability of Teacher Education Graduates
The purpose of this study was to determine whether College of Education graduates who sought and secured employment as teachers differed on the academic variables of grade point average, student teaching evaluation, and professional recommendations from those who were not successful at securing such employment. A comprehensive review of related literature was conducted, focusing on three aspects of the employment situation: (1) teacher supply and demand, (2) the selection process, and (3) the role played by academic criteria in the selection process. A study was conducted in which students who were successful in finding teaching positions were compared with those who were not successful, on the academic variables of grade point average, student teaching evaluation, and professional recommendations. Demographic data were also collected and analyzed. The subjects were sixty-three randomly selected students from the May 19 80 graduating class of the College of Education, North Texas State University, Denton, Texas. For purposes of statistical analysis, the students were divided into the following three groups: Group A (those who successfully sought employment as teachers), Group B (those who sought such employment but were not successful), and Group C (those who did not seek employment as teachers).

The Design and Evaluation of Study Materials for Integrating Musical Information into the Choral Rehearsal
The purpose of the study was to design and evaluate materials for integrating musical concepts and stylistic concepts into the high school choral rehearsal. Need for the study was established by examining related literature and by means of a survey of Texas high school choral directors. A systems approach model of curriculum development, consisting of a ten-step procedural outline, was adopted for formulation of the study. The following criteria for the curriculum, called Integrated Musical Information for Choirs (IMIC), were set: (1) Materials should be in the hands of each student; (2) Materials would relate directly to music being performed by the choir; (3) Use of the materials should assist the teacher in organizing his/her work; (4) Teachers should be able to put materials into use without adaptation; (5) Teachers' out-of-class preparation should be minimal.

A Study of Disparity in Effort Among Texas School Districts for Debt Service, as Well as for Maintenance and Operation
The problem with which this investigation is concerned is that of determining the degree to which fiscal disparity in Texas school districts affects debt service, as well as maintenance and operation and local enrichment. This study has four main purposes: to determine whether the poor school districts are exerting more or less effort for debt service, maintenance and operation and total taxation than are the wealthy districts; to determine how the size of Texas school districts is related to district wealth; to determine the number of Texas school districts that do not levy a tax for debt service; and to provide information for persons interested in school finance matters—namely, legislators, educators, students of finance and lay citizens who may or may not be property taxpayers.

A Comparative Content Analysis of Texas and Thai High School Biology Textbooks
There were two purposes of this study. The first was that of determining, through an analysis of Texas and Thai biology textbooks, which objectives -- cognitive, affective, manual skill, processes of scientific inquiry, and orientation—were emphasized in three major and twenty-seven minor fields of biology. The second purpose was to determine if significant differences exist in the frequency distribution of these objectives. Only one biology program is used in schools throughout Thailand. This program, which was published by the Ministry of Education, consists of four textbooks with 1977 copyright date. The five Texas textbooks used in this study were those adopted under the provisions of the Textbook Law. The contents of each of the six texts included in the study were classified by using the criteria of Klopfer's Table of Specifications for Science Education.

The Role of the Elementary School Counselor in Texas as Perceived by Elementary Principals and Elementary School Counselors
The problem of this study was to answer the question, of whether or not there is congruence between Texas elementary school counselors' and elementary principals' perceptions of the role of Texas elementary school counselors. Research questions were formulated to carry out the purpose of this study. A review of related literature revealed that only two studies of the role of the elementary school counselor had been conducted in Texas. Both studies polled only elementary school counselors; therefore, Texas elementary principals' perception of the role of the elementary counselor was unknown. Christian's Elementary Counselor Inventory (ECI) was the instrument used in this study. The ECI contains 60 items describing tasks likely to be part of the counselor's role. Respondents were asked to consider each task twice; once according to the ideal role (should this be part of the counselor's role?), and once according to the actual role (is the elementary school counselor actually performing this function?).

A Psychological Investigation of the Expressed Attitudes of Single Undergraduate College Students Toward Marriage and Family Life
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 .

Application of the Materials Management Concept to the Hospital Purchasing Organization
Hospitals have increasingly come under close public scrutiny in the last several years because of the constantly escalating price of health care in the United States. It has been estimated that approximately 30 per cent of a typical hospital's operational budget is devoted to purchasing consumables plus the cost of materials support. The purpose of this study is to examine and compare materials management practices of selected individual hospitals in Texas Health Services Area 5 in order to determine the extent and manner in which they utilize the materials management concept. In addition, the investigation focuses on determining if there are any relationships between the variables of type of ownership, size and the extent to which the study hospitals utilize the materials management concept.

A Study of the Effects of Three Texas School Finance Bills and Title I of the Elementary and Secondary Education Act of 1965 on Fiscal Equity in Operating Revenue
The purpose of this study was to compare per pupil receipts for operation in most school districts in Texas based on the changes in State funding provided for by three major finance bills and to analyze the effects of federal monies provided by Title I of the Elementary and Secondary Education Act of 1965 to determine the degree of equity in the State's school finance structure. The population consisted of 973 public school districts reporting all data for 1974-75, 1976-77, and 1977-78. The districts were grouped into ten wealth deciles based on School Tax Assessment Practices Board assessed property value per student in average daily attendance. A weighted mean value for each decile for each category and year of funding was computed. Correlation coefficients were computed to provide an index of relationship between the categories of dollars available per pupil for operations. Coefficients of variation were determined to express the magnitude of variation relative to the average value for each additive category for each decile.

A Comparison of Perceptions Concerning Differential Salary Compensation for Teachers in the Eight Largest School Districts of Texas
The problem of this study was to determine if educationally, politically, and economically viable alternatives to the single salary schedule for teachers exist in the eight largest school districts in Texas. After a review of the literature, a questionnaire was developed designed to obtain views of superintendents, school board members, randomly selected principals, teachers, and PTA members in the eight school districts on these issues: whether a multi-factor teacher salary schedule should be developed; which factors should be included in such a system; what amount of monetary compensation should be awarded for each factor; and if teacher job performance is a factor, what criteria should be used to evaluate teachers and who would conduct the evaluations. Analyses of the data were conducted according to the following demographic variables: school district; position, sex, and ethnicity of the respondents; whether the respondents owned homes in the school districts; and whether the respondents had children enrolled in the district schools. The results were presented for the respondents as a whole and according to the various demographic variables.

Impact of Labor Union Representation Elections on Wages and Selected Employer-Employee Relations in Nonprofit Hospitals in Texas
This study concerns the general question, "What has been the impact of collective bargaining representation elections on nonprofit hospitals in Texas?" The means of answering this question involved a study of wages and attitudes of nonprofessional employees in both hospitals where such elections occurred and hospitals where no such elections had occurred in the State of Texas. An overview of the development of hospitals and the union movement in hospitals are presented as background information for this study. Further, a brief discourse on attitude development and attitude measurement is provided as theoretical foundational material. A researcher-constructed questionnaire was devised, tested, and administered to employees of the subject hospitals. There were 176 useable returns from employees where no union representation election occurred and 176 useable returns from employees where union representation elections occurred.
