The problem with which this investigation is concerned is that of facial muscle activity in forming and maintaining the soprano clarinet embouchure. The purposes of the study are to collect and analyze data in the following areas: 1. Activity of the following muscles during performance on the clarinet: (1) upper orbicularis oris, (2) lower orbicularis oris, (3) upper half of the buccinator, and (4) lower half of the buccinator. Muscular activity is read as electronic potential and is presented on recordings through the use of electromyography. 2. Possible effects which the electromyographic apparatus might impose upon performance. Tape recordings weremade of the subjects' performing prescribed tasks both before and during electromyographic analysis. The possible effects of the electromyographic analysis upon performance were then tested by comparing these two recordings.

This study seeks to develop and evaluate a program of selfinstructional drill materials for improving the ability of students to detect pitch errors in choral singing. The specific purposes of the study are as follows: (1) To develop and validate a visualaural test for pitch-error detection; (2) to develop a visual-aural, self-instructional program for improving the ability of students to detect pitch errors; and (3) To determine whether the program of self-instructional drill materials modifies the ability to detect pitch errors. In the first phase of this three-phase study, a body of testing materials was assembled, pilot-tested, edited, and judged reliable for use. In Phase II a body of self-instructional, programmed drill materials was assembled, pilot-tested, corrected, and judged ready for evaluation. In Phase III the procedures were as follows: (1) the subjects for whom the program was intended were administered a pretest of their pitch-error detection ability; (2) one group (A) participated in the programmed drill materials developed, while the other group (B) used no programmed materials; (3) both groups were administered a midtest to determine whether there was any change; (4) the latter group (B) participated in the programed drill materials developed, while the first group (A) no …

The purposes of this study are to identify and describe the function and control of facial muscles as related to sound production on brasswind instruments, to explore electromyographic theory and techniques with particular regard to the function and control of facial muscles, to identify basic theories of embouchure among brasswind teachers and performers, to develop a theory of brasswind embouchure based upon the preceding factors, and to propose recommendations with regard to brasswind pedagogy. Existing theories of embouchure were investigated by reviewing the extensive brasswind pedagogical literature, and by interviewing teachers representing two widely differing views. Electromyographic kinesiology of facial muscles was investigated as follows: a description of facial muscles was formulated by collating anatomy books; related electromyographic literature was reviewed; eloctromyographic recordings of facial muscled during, the performance of various facial muscle tasks and during brasswind performance were made using indwelling fine-wire electrodes. The following fundamental questions were raised: (1) What are the elements of brasswind embouchure, and what is the effect of each upon performance? (2) Is there a single embouchure mode which may be considered most efficient, and if so, what facial muscles are involved, and how may they be trained?

The problem of this study was to develop a proposal for the teaching of poetry for the purposes of contributing to the student's understanding and enjoyment. Surveys and summaries were made of scholarly writings on the junior college student, existential theories of education, and theories of poetry. A bibliography was constructed for each subject from resources of the North Texas State University library. Conclusions from each survey were derived from the selected resources and used to prepare the proposal for instruction of poetry.

This study evaluates the effectiveness of programed vocabulary instruction in an undergraduate collegiate business communications course. In making its evaluation, the study tests the hypothesis that a class using such instruction would improve over a class without formal vocabulary study. The three areas of proficiency measured are written communication, vocabulary, and reading comprehension.

The purposes of the study were to: 1. Determine the level of test anxiety present, as measured by the Test Anxiety Questionnaire (TAQ), prior to treatment. 2. Develop an implosive therapy procedure to reduce test anxiety. 3. Administer implosive therapy to subjects in the experimental treatment group. 4. Determine the post-treatment level of test anxiety in the implosive therapy group, placebo-attention control group, and the no-treatment control group. 5. Determine if there were any significant differences in the test anxiety levels in the three groups on the post-treatment TAQ. 6. Investigate the results of a one month follow-up administration of the TAQ to determine the relative stability of test scores.

Dealing with the college laboratory program in general chemistry, this study compares the effects of exercises based on current national problems with the effects of traditional laboratory exercises. The study has been prompted by the recent emphasis on topics of national interest in the undergraduate chemistry curriculum. These topics include air and water pollution, drug addiction and analysis, tetraethyl-lead additives, insecticides in the environment, and recycling of wastes. The relevant experiments are taken from recent issues of the Journal of Chemical Education. The traditional exercises, from the laboratory manual Chemistry in the Laboratory, by Watt, Hatch, and Lagowski (New York, Norton, 1964), deal with such topics as chemical composition, gas laws, solutions, and acids and bases.

The problem with which this study was concerned was to identify employment status of the 1964-1971 industrial arts majors who graduated from the colleges and universities in Texas. Specifically this study analyzed the status of the following industrial arts graduates: those with and without teaching certificates, those in educational employment, those in industrial employment, those who had changed their employment from education to industrial or self-employment and vice versa, and those who returned to campus for further studies.

The problem with which this investigation is concerned is that of providing a current academic and racial description of the intercollegiate football participants at North Texas State University and the construction of a current participants' profile. The subjects employed were 259 football participants from the 1966 Fall Semester through the 1971 Fall Semester, The descriptive analysis is based upon 234 participants; the profile is a composite of eighty-one currently (1971) enrolled participants, This study has a twofold purpose, The first is to provide a current description of the academic status of both white and non-white participants; the second is to construct a current profile of the participants, The study is designed with the idea that the findings could be of use to coaches and administrators of this university in football programming, Transcripts, coaches, and the Public Information Office of this university provided the data used in the descriptive analysis, Eighty-one participants answering self-report questionnaires provided data for the profile,

The problem with which this investigation is concerned is that of determining the relative effectiveness of the Christensen Rhetoric Program and of a traditional write-revise approach in freshman English composition classes.

This investigation is concerned with the problem of identifying and analyzing kinds of information needed by community junior college students about career opportunities in business, as perceived by students, business teachers, and counselors in community junior colleges.
