The Effect of Three Compositional Structures on the Compositional and Instructional Self-efficacy of Pre-service Music Teachers

The Effect of Three Compositional Structures on the Compositional and Instructional Self-efficacy of Pre-service Music Teachers

Date: August 2012
Creator: Hauser, Christian Vernon
Description: The purpose of this study was two-fold: 1) to compare the effects of three different composition tasks with varying degrees of structure on pre-service music teachers’ creative self-efficacy as composers and their instructional self-efficacy as pedagogues of composition; and 2) to describe through pre-service music teachers’ talk perceptions of composition and their experiences completing the three composition tasks. Participants (N = 29) were music education majors from three different sized universities in the northern-central region of the United States. At the beginning of the study, the participants answered a researcher-design self-efficacy questionnaire that measured (a) their self-efficacy as composers and (b) their self-efficacy as teachers of composition. Next, they composed three compositions of various task structures (unstructured, poem, and rhythm). Immediately after completing each task they again completed the self-efficacy questionnaire. Statistically significant mean differences between the pre-task administration of the measuring instrument and all three composition tasks were found for the pre-service teachers’ compositional self-efficacy. Statistically significant mean differences were also found between the unstructured task and the rhythm task, but not between the rhythm and poem tasks or the unstructured and poem tasks. For the pre-service teachers’ self-efficacy as pedagogues of composition question, the results were also statistically ...

The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children

The Effect of Three Different Levels of Skill Training in Musical Timbre Discrimination on Alphabet Sound Discrimination in Pre-Kindergarten and Kindergarten Children

Date: May 2000
Creator: Battle, Julia Blair
Description: The purpose of this study was to investigate the effects of three different levels of skill training in musical timbre discrimination on alphabet sound discrimination in pre-kindergarten and kindergarten children. The findings of prior investigations indicated similarities between aural music and language perception. Psychoacoustic and neurological findings have reported the discrimination of alphabet quality and musical timbre to be similar perceptual functions and have provided, through imaging technology, physical evidence of music learning simultaneously stimulating non-musical areas of the brain. This investigator hypothesized that timbre discrimination, the process of differentiating the characteristic quality of one complex sound from another of identical pitch and loudness, may have been a common factor between music and alphabet sound discrimination. Existing studies had not explored this relationship or the effects of directly teaching for transfer on learning generalization between skills used for the discrimination of musical timbre and alphabet sounds. Variables identified as similar from the literature were the discrimination of same- different musical and alphabet sounds, visual recognition of musical and alphabet pictures as sound sources, and association of alphabet and musical sounds with matching symbols. A randomized pre-post test design with intermittent measures was used to implement the study. There were 5 ...

Date: May 2008
Creator: Vincent, Lynette Susanne
Description: The main purpose of this study was to consider the effects of amplification and vocal function exercises on the perceived vocal health of elementary music educators (N = 37) from Oklahoma (n = 11) and Texas (n = 26). Participants were assigned to the use of the ChatterVoxTM amplifier or vocal function exercises based on pretest scores on the Voice Handicap Index with Music Teacher Voice Questionnaire (VHI/MVQ). Following the 4-week study period, participants completed the posttest VHI/MVQ. The results of a one-way ANCOVA that used treatment group as the independent variable, the summed posttest scores as the dependent variable, and the summed pretest scores as the covariate or control variable indicated that there was a statistically significant difference between the adjusted means for the posttest scores, favoring the exercises group. The overall group and both treatment groups reported frequent loud voice use in work settings and in public places. The overall group and the amplification group reported hoarseness after prolonged talking. The exercises group did not report as great a problem with hoarseness after prolonged talking. Secondary purposes addressed demographic variables. Women perceived greater overall vocal difficulties than men; men frequently reported specific vocal complaints that were not commonly ...

The Effects of Free Play As an Instructional Tool on the Quality of Improvisation of First, Second, and Third Grade Children

The Effects of Free Play As an Instructional Tool on the Quality of Improvisation of First, Second, and Third Grade Children

Date: December 2000
Creator: Burger, Tammie L.
Description: To look at the effect of free play on the musical improvisations of first, second and third grade children, 108 children were randomly assigned to either a control or treatment group. Subjects were tested using a researcher-designed instrument to elicit an improvisatory response. The control group then received regular music instruction (120 minutes every 2 weeks) and the treatment group received regular music instruction in conjunction with musical free play (100 minutes of instruction and 20 minutes of free play every 2 weeks). The treatment lasted 14 weeks. At the end of the treatment, all students were tested with the same testing instrument used for the pre test. Videotapes of the improvisations were submitted to three independent judges to rate for quality on a 5-point Likert scale. The change in ratings between pre and post tests were analyzed with an analysis of variance to determine if there were significant differences between the control and treatment groups. The analysis of the data revealed no significant difference in the change of ratings between control and treatment groups for the group as a whole, or for any particular grade level within the total group.

The Effects of Instruction on the Singing Ability of Children Ages 5-11: a Meta-analysis

Date: August 2015
Creator: Svec, Christina L.
Description: The purpose of the meta-analysis was to address the varied and somewhat stratified study results within the area of singing ability and instruction by statistically summarizing the data of related studies. An analysis yielded a small overall mean effect size for instruction across 34 studies, 433 unique effects, and 5,497 participants ranging in age from 5- to 11-years old (g = 0.43). The largest overall study effect size across categorical variables included the effects of same and different discrimination techniques on mean score gains. The largest overall effect size across categorical moderator variables included research design: Pretest-posttest 1 group design. Overall mean effects by primary moderator variable ranged from trivial to moderate. Feedback yielded the largest effect regarding teaching condition, 8-year-old children yielded the largest effect regarding age, girls yielded the largest effect regarding gender, the Boardman assessment measure yielded the largest effect regarding measurement instrument, and song accuracy yielded the largest effect regarding measured task. Conclusions address implications for teaching, research pedagogy, and research practice within the field of music education.

The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.

The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.

Date: May 2003
Creator: Cahn, Dan
Description: The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction ...

Elementary music teachers instructing English language learners: Reflection on practice.

Elementary music teachers instructing English language learners: Reflection on practice.

Date: December 2005
Creator: Scherler, Kathy L.
Description: This qualitative study investigated four monolingual, English-only speaking Caucasian elementary music teachers and their reflections regarding instruction of English language learners (ELL). The purpose of this multiple case study was to investigate the teaching practice and curricular decisions of elementary music teachers who instruct Hispanic ELL students. The investigation was conducted during a nine-week period, and data collection included classroom observations, phenomenological interviewing, and teacher audio journals. None of the teachers had prior education or pre-service preparation in teaching music to ELL students. The major theoretical base from which the study was developed was the reflective teaching theory of Donald Schön (1983). The main research question was: "What are the participating teachers' reflections about their curricular and pedagogical decisions when teaching ELL students?" Following a description of the elementary music teachers' reflections on practice with ELL students, the study revealed that the majority of elementary music teachers had a lack of preparation and ELL music curriculum, and negative perceptions of the placement program for ESL students. Despite these factors, the teachers made attempts to include ELL students in all music activities. This study showed that while one teacher accommodated specifically for the ELL students' learning, three out of four teachers ...

An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson

An Examination of the Presence of Schön's Concept of "Reflective Conversation" as a Defining Component in the Applied Studio Music Lesson

Date: December 1995
Creator: Murphy, Vanissa B. (Vanissa Braswell)
Description: The purpose of this study was to examine the presence of Schön's concept of reflective conversation as a defining component in the applied studio music lesson. The research problems were (1) to determine the presence of complete and incomplete reflective conversations; (2) to determine the verbally exhibited knowledge base within complete conversations in relationship to conversation length; and (3) to establish an instructional profile of stable behaviors based on reflective conversation as a distinguishing characteristic among selected teachers. Videotapes of twenty-six applied studio music lessons of thirteen university teachers were analyzed according to problem solving, on-the-spot experimentation, and evaluation. An observation form was developed and was a reliable tool to collect information concerning number and type of reflective conversations, conversation length, and the teachers' verbally demonstrated knowledge base. Knowledge base was obtained by using the procedural model of Flanagan's critical incident technique. Reflective conversations existed and were a distinguishing characteristic of the teachers. With the exception of two teachers, a stable use of both number and length of reflective conversations, and knowledge base areas, was found. A discernible difference in the teachers' knowledge base within conversation length existed, and thus established instructional profiles for the teachers. Complete reflective conversations ranged ...

Experiencing the interdependent nature of musicianship and educatorship as defined by David J. Elliott in the context of the collegiate level vocal jazz ensemble.

Date: August 2005
Creator: Jensen-Hole, Catherine
Description: Examination of the relationship of musicianship and educatorship of teacher and students as interacting partners in a specific musical context proceeded with investigation of how formal, informal, impressionistic, and supervisory musical and educational knowledge were evidenced in rehearsal. Attention was also given to how the teaching strategies of modeling, coaching, scaffolding, fading, articulating, reflecting comparatively, and exploring were used to develop student musicianship. The research methodology may best be described as an inductive analytical case study approach. Multiple data sources included: videotaped observations of 19 bi-weekly rehearsals, audio taped interviews of the 12 participants, supplemental materials, (a published interview, journal articles, rehearsal schedules), and member checking with the teacher and David Elliott. Rehearsal data were initially organized into categories identified in David J. Elliott's (1995) model. The relationship of teacher and student musicianship, and teacher educatorship emerged during analysis. Musical details of problem finding, reducing and solving were also identified. Three themes emerged from the student interviews: their perceptions of the teacher's musicianship, general rehearsal strategies, and the teacher's use of specific teaching strategies. Interviews with the teacher illuminated his perception of musicianship and teaching strategies employed in the context. The findings confirmed that as music making transpired in the ...

High School Contemporary a Cappella: a Descriptive Phenomenology

High School Contemporary a Cappella: a Descriptive Phenomenology

Date: December 2015
Creator: Burlin Sr., Thomas B.
Description: This study examines the phenomenon of contemporary a cappella music making found in high school settings as curricular and extra-curricular offerings. Past music and music education literature has focused exclusively on contemporary a cappella at the collegiate level. Through application of a descriptive phenomenological method and incorporation an educational-sociological lens, this study advances an understanding of the educational benefit and social value of membership in contemporary a cappella at the high school level. Six recent members from three regions of the United States provided data through individual open-form interviews in which questions were derived from the participants’ own speech. I incorporated phenomenological reductions and processes to negate researcher bias during data collection, analysis, and the formation of a general structure and constituent meanings of membership in high school contemporary a cappella. Participants utilized traditional music skills, individual talents, conceptions of popular culture and music, and in-group socialization to facilitate music making and reify membership. Expressing the value of group membership, individuals acted to benefit the group by cultivating social bonds, developing and fostering personal/shared connections to songs, identifying and purposing individual talents and skills, and gaining an understanding of each members’ unique contribution to membership. Discussion includes implications for music ...

Date: December 2003
Creator: Brumbaugh, Sherron M.
Description: The purpose of this study was to describe 11th- and 12th-grade high school string orchestra students in Texas public schools in terms of their decision to enter the field of string orchestra teaching as a possible career choice or to pursue another field of study. Convenience sampling techniques were used to secure a study population of 1,683 high school string orchestra students. The Junior and Senior High School String Orchestra Student Survey (researcher designed) was used to gather demographic characteristics, students' perceptions on selected intrinsic/extrinsic work values, tangible elements of teaching, intrinsic characteristics of string orchestra teaching, and individuals assisting in students' career choices. Selected elements of teaching cited by students for their lack of interest in string orchestra teaching were also reviewed. Analysis procedures for descriptive statistics included measures of central tendency, crosstabulation, frequencies and percentages. Consistent with prior research, it was found that a larger number of female students over male students were interested in string orchestra teaching. Students interested in fields outside of string orchestra teaching reported higher class grades, more honors and advanced classes and higher SAT/ACT mean scores. Students interested in string orchestra teaching reported a higher percentage of brothers/sisters, mothers and fathers who played ...

Improvisation in the Beginning Piano Class

Improvisation in the Beginning Piano Class

Date: December 1977
Creator: Jones, Nancy Ragsdale
Description: The problem was to survey and collect ideas on the use of improvisation as a teaching and learning tool in elementary piano instruction and to prescribe activities and exercises for second through fourth grade piano classes. These areas were examined: philosophies and theories influencing traditional instruction, effects of creative keyboard activities on children's musical development, specific teaching strategies using improvisation, evaluative procedures, and suitability of materials for young children. Data collected from published and unpublished materials were classified, and presented concerning the feasibility of using keyboard improvisation with early elementary children. It was found that suitable improvisational exercises allow the child to organize his perceptions into the basic concepts of music. Recommendations for teachers and researchers were made.

An Investigation into the Stability of Students' Timbre Preferences from the Sixth through the Tenth Grade

Date: May 1995
Creator: May, Brack M. (Brack Miles)
Description: The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.

Date: August 1989
Creator: Allen, Michael, 1954-
Description: Holland's theory of vocational personalities and work environments incorporates four theoretical constructs (congruence, consistency, differentiation and identity) which attempt to explain sources in variability of achievement and satisfaction among employed adults and college students. This study sought to: (1) investigate the relationship of Holland's constructs to academic achievement and educational satisfaction of undergraduate music majors; (2) investigate differences in all variables according to gender and degree major. Data were collected from undergraduate music majors (N = 100) enrolled at the University of North Texas using the Vocational Preference Inventory. Mv Vocational Situation. and the Music Major Satisfaction Questionnaire. Reliability for the Music Major Satisfaction Questionnaire was estimated at .92 using Cronbach's coefficient alpha. Pearson product-moment correlation coefficients indicated that: (1) congruence was significantly related to academic achievement and educational satisfaction; (2) identity was significantly related to academic achievement and educational satisfaction; (3) consistency was significantly related to academic achievement, but not to educational satisfaction; (4) differentiation was significantly related to academic achievement, but not to educational satisfaction. Multiple regression using a stepwise entry method indicated that: (1) the identity construct was the best predictor of educational satisfaction scores; (2) identity was the best predictor of academic achievement scores.

Creator: Williams, Bonnie Blu
Description: 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 ...

An Investigation of Selected Muscle Potential Activity in Violin/Viola Vibrato

Date: August 1995
Creator: Weber, Matthew J. (Matthew Joseph)
Description: The purpose was to investigate muscle potential during the vibrato motion for successful, healthy violin/viola performers. Electromyography was used to analyze parameters of muscle potentials during performance of a standardized exercise. These parameters were (a) evidence of potentials, (b) patterns of potentials, and (c) timing relationships (24 muscles). This study also sought to replicate and expand performance data from previous studies. Procedures from three pilot studies were used to standardize collection of EMG data. Synchronized video recordings were used to determine vibrato speed and conduct motion analysis. EMG data processing prior to analysis included power spectrum analysis and rectification, low-pass filtering, and smoothing data. Motion analysis findings (£D) were 1.09 for the elbow joints and 3.25 for the wrist joints. which was an indication of range of motion, suggested much greater activity in muscles controlling wrist movement than those moving the elbow. The degree of muscle potential and control were generally related to distance from the vibrating hand. Forearm muscle groups (8) demonstrated the greatest evidence of potential (76.5%) and were 18.1% non-periodic. Muscles of the upper arm (7) were off 59.4% and 57.0% non-periodic. Upper arm muscles had greater individual differences. Muscles of the chest and back (9) were ...

An Investigation of the Influence of Evaluator Background on Appraisals of a Music Lesson Using the Texas Teacher Appraisal System

Date: December 1997
Creator: Bohnstengel, Carol
Description: This study's purpose was to investigate the differences in scores and written comments given by two appraisal groups in their evaluation of a music teacher using the Texas Teacher Appraisal System (TTAS). One appraiser group had musical training while the other group specialized in other subjects. Analyses of both group's appraisal scores showed no significant differences. An examination of the written comments revealed that both appraisal groups focused on the same aspects of the lesson and used similar vocabulary. The TTAS instrument was a consistent measure of generic teacher behaviors in the music lesson, but it did not measure specific music teaching behaviors or encourage suggestions for improving musical instruction.
