Line width parameters for a number of spectral lines in the pure rotational spectrum of formaldehyde (CH20) and formic acid (HCOOH) have been measured using a sourcemodulated microwave spectrograph. All transitions studied in this investigation were of the type ΔJ=O (i.e. Q-branch transitions), with ΔK-1=0 and ΔK+1 =+l. The center frequencies of the measured lines varied from 8662.0 MHz to 48612.70 MHz. The experimentally determined collision diameters for self broadening interactions involving HCOOH and CH2 Q molecules were found to be 2 - 27 per cent less than those calculated by the Murphy-Boggs theory of collision broadening. Much better agreement between a simplified broadening scheme for symmetric top molecules and the observed foreign-gas collision diameters is obtained by using Birnbaum's theory.

Literature in the area of play was surveyed, summarized, and organized. The historical approach was used for the collection of data for this study. Materials gathered were acquired through the sources provided by library services as well as current authorities in the field of play therapy. As the material was collected, the focus areas or sections began to naturally develop because of the commonality of the articles. The material found was divided into theory, approach, position, and research. The material found on theory and approach was organized into Chapter II. The material found on position and research was organized into Chapter III. Body movements of both child and therapist offer much research possibility. Since most of the child's language is nonverbal, it is critical that persons develop ways of evaluating and identifying his body signals. Research is needed on the potential use of every toy which is included in the playroom. Research is needed on the potential potency and effect of every type limit set within the play therapy process. Research is needed on the effect of the therapist on the process. Research is needed in reference to training models for the development of play therapy skills in professionals, paraprofessionals, …

The problem of this study has been an investigation and comparison of the school dropout rates of Mexican American and Anglo Students and their reasons for leaving school in a large metropolitan school district in Texas. The specific purposes were (1) to ascertain the dropout rates of Mexican American and Anglo students within similar socioeconomic status and to compare these rates; (2) to compare the reasons for dropping out of school given by Mexican American and Anglo students; and (3) to delineate the implications for the school district's instructional program and its operation. Based on an analysis of the findings of this study, the following conclusions were formulated: (1) the school district studied is not meeting the needs of Mexican American students, particularly Mexican American females; (2) it can be expected that Mexican American female students are more likely to drop out than are Anglo females; and (3) Mexican American and Anglo dropouts do not believe that there is anyone on the school staff in whom they can confide their decision to drop out.

The problem of this study is the development of a model curriculum for high school metallurgy students. The study was made at the Skyline Career Development Center of the Dallas Independent School District, Dallas, Texas. The study has three purposes. In addition to providing a model curriculum for high school metallurgy students, a second purpose is to describe the developmental processes by which the curriculum was derived. The third purpose is the evaluation of the basis of the content of the model curriculum. It was found that of the 76 concept-relationships stated, 64 were true as originally written according to the established rating criteria. It was also found that 64 of the 76 concept relationships stated were appropriate for understanding by high school students, although the two lists of 64 concepts were not identical. The unapproved concept statements were deleted or rewritten according to the established criteria. Only one of the 33 skills listed received a low rating. It was further found from a report of the metallurgy instructor that the 21 high school students in the metallurgy program had attempted a cumulative total of 374 of the 33 behavioral objectives in the curriculum and had accomplished a total of …

The purpose of this study was to examine the effectiveness of a school-developed continuous-progress program in mathematics in terms of how well students achieved in arithmetic computation, concepts, and applications. The study also investigated the student's attitude toward arithmetic. Conclusions and Recommendations: 1. All students in grades four through six favored the continuous progress program over the conventional program in terms of arithmetic computation and concepts. Grades four through seven favored the continuous progress program in terms of arithmetic applications. A trend was noted that indicated the program was more effective for lower grade levels. It is recommended that the continuous progress be used with all fourth and fifth grade students and that a longitudinal study be developed for the fourth and fifth grades as they continue the experimental program through the eighth grade. 2. Sex is a doubtful factor in determining the effectiveness of the continuous progress program. A trend did appear in the area of arithmetic computation that indicated sex may be a greater factor in this variable than in the other three variables studied. It is recommended that further study be done concerning the relationship of sex to arithmetic achievement when using a continuous progress concept. 3. …

This research study was developed to investigate whether a structured discussion group on feelings)in combination with play group counseling can be effective as an intervention approach in working with disadvantaged primary grade children who are exhibiting disruptive classroom behavior. The general nature of the research hypotheses was that developmental play group counseling would not only reduce disruptive behavior of disadvantaged second grade students, but would also help to enhance these students' self concepts and attitudes toward school. None of the six hypotheses were confirmed. Developmental play group counseling did not significantly reduce "classroom disturbance" behavior, improve perceived self image, or improve attitude toward school over periods of time. The data indicated that play group counseling did significantly reduce "classroom disturbance" behavior after seven weeks of treatment, and maintained that general level of improvement eight weeks after the end of the study. The above finding suggested that play group counseling be utilized with disadvantaged early primary grade children who present behavior problems in school.

The problem of this study involved the identification of white student teacher racial attitudes relative to blacks and whether these attitudes changed during the course of student teaching. The purpose of the study was to determine the nature of these racial attitudes, to determine if these attitudes were influenced by the experience of student teaching or the racial environment in which student teaching was accomplished, and, in light of the findings of the study, either to reinforce the manner in which racial attitudes are treated in traditional teacher preparation programs or suggest new directions in the curriculum that might lead to more realistic and desirable teacher attitudes. In light of the above findings, the following conclusions seem warranted: 1. The contact thesis of racial attitude change is confirmed. However, among experimental group subjects, the nature of the contact achieved was incongruous with what research has found to be most conducive to positive attitude change. 2. Racial attitudes are so deeply and emotionally embedded that attitude change, if it is to be accomplished, should be treated as a priority item, and any programmed attempt to alter racial prejudice should be comprehensive in design.

The problem of this study was an investigation of teacher and administrator perceptions of teacher evaluation and the relationship of those perceptions to teacher evaluation policies and practices in public high schools in the State of Texas.

The problem of this study was to examine the selection process used in the appointment of high school principals in the forty-eight large-city school districts of the nation. The purposes of this study were (1) to examine how principals of high schools in large-city districts are selected, and (2) to determine the criteria considered important in the selection process. In order to conduct this investigation a questionnaire was developed. The questionnaire was validated by a twelve-member panel composed of eleven public school administrators and a former United States Commissioner of Education. Significant findings which tend to be supported by the data are: 1. Human relations skills were considered as being most important in selecting principals. 2. Superintendents placed little value on the personal traits of candidates. 3. Instructional skills ranked third in importance. 4. The selection process depended heavily on biographical data and the use of the interview. 5. Teaching experience and a master's degree are essential. 6. Assistant superintendents are involved in the selection process more often than any other group, but superintendents are most influential in the selection process. 7. School facilities, pupils, and parents are seldom involved in the selection process, and when involved, their influence is …

The problem of this study was the assessment of the value of the Tennessee Self Concept Scale, the DF Opinion Survey, and An Inventory of Factors STDCR for use in identifying personality factors significant to overseas adjustment. The following conclusions were drawn: 1. The TSCS and the DFOS lacked validity as predictors of personal adjustment as measured by the MPAS. 2. Freedom from depression tendencies (Factor D) and freedom from fluctuating emotions (Factor C) of the STDCR were significantly related to overseas adjustment. 3. The best combination of factor scores for predicting personal adjustment included D (Depression), CC (Cultural Conformity), and S (Social Introversion-Extraversion). 4. The Candidate Graduate Training Program was not effective in producing change in the psychological factors tested.

The problem of this study was to determine and report the attitudes of selected undergraduate military veterans toward selected campus organizations at North Texas State University. The purpose of this study was to provide a basis for evaluating and possibly improving the campus organizations at this university. As a result of this study, it was concluded that the majority of responding veterans had very little knowledge concerning the majority of campus organizations. It was concluded that the majority of responding veterans preferred the miscellaneous type of organizations as opposed to the national honorary and professional, departmental, and social types. It was also concluded that all the responding veterans stated the overall groups of campus organizations were between "good" and "fair," and felt they needed help from their advisors about the organizations on this campus.
