- The Effect of Ethnicity on the Age-of-onset of the Male Voice Change.
- The purposes of this study were to describe the characteristics of the changing male voice in 4th, 5th and 6th grade students using Cooksey's maturation stages and, to compare the age-of-onset of the male voice change in African American, White, and Hispanic male students. Participants included volunteer 4th (n = 61), 5th (n = 73), and 6th grade male students (n = 63) from 2 urban elementary schools, 5 suburban elementary schools, 1 suburban middle school and 1 urban middle school in the North Texas region. The three ethnic groups represented in this study were: African American (n = 62), White (n = 58), and Hispanic (n = 77). Results indicated that approximately 46% of 4th grade participants, 62% of 5th grade participants, and 67% of 6th grade participants were classified as changing voices. A descriptively larger percentage of African American participants were classified as changing voices than Hispanic and White participants. Also, a larger percentage of African American and Hispanic participants were descriptively classified in the more advanced stages of the voice change than White participants. Urban African American, White, and Hispanic participants had a larger percentage of males classified as changing voices than suburban African American, White, and Hispanic participants. Results of a one-way, between subjects ANOVA revealed no significant main effect for ethnicity, F (2, 51) = .42, p = .66, η2 = .02. The overall mean age-of-onset for participants in this study was approximately 11.20 years of age.
- An Investigation of the Nonverbal Communication Behaviors and Role Perceptions of Pre-Service Band Teachers who Participated in Theatre Seminars
- This qualitative study used a multiple case study methodology to explore the nonverbal communication behaviors and role perceptions of pre-service band teachers, and the extent to which these individuals found meaning and value in theatre seminars with respect to those factors. The informants participated in three theatre seminars taught by theatre faculty at the researcher's university. The researcher collected data in the form of videotaped theatre seminar observations, videotaped classroom teaching observations, videotaped informant reflections of teaching episodes, online peer discussions and journaling, and informant interviews. Data were analyzed, coded, and summarized to form case summaries. A cross-case analysis was performed to identify emergent themes. The broad themes identified were past experience, adaptation, realization, and being aware. The informants found that the theatre seminars increased their awareness of nonverbal communication behaviors in the classroom, and had the potential to be meaningful and valuable with respect to their perceptions of their roles as teachers.
- String student self-efficacy and deliberate music practice: Examining string students' musical background characteristics, self-efficacy beliefs and practice behaviors.
- This study examined the musical background characteristics, self-efficacy beliefs, and practice behaviors of string students auditioning for an all-region orchestra in one large South-Central district. Purposes of the study were: (1) to describe the musical backgrounds and self-efficacy beliefs of high school string students, (2) to measure the relationship between self-efficacy scores and performance achievement, and (3) to describe the practice behaviors and thoughts of high and low self-efficacy string students. Questionnaires were given to 101 high school string students; 65 competed in all-region orchestra. Descriptive data from the questionnaire revealed information such as how many took private lessons and that those who did tended to have a higher sense of perceived self-efficacy in relation to playing their string instruments. Other descriptive items asked questions such as whether or not students started in public school and how much they practiced outside of orchestra. The relationship of summed self-efficacy scores to a competition ranking was found to be statistically significant and inverse. For all string participants (n=65) Spearman's rho was, rs= -.37, (p=.001) with 14% of the variance explained (r2 =.14). This inverse relationship documents the linear trend for students with better rankings (lower ranking numbers) to also tend to have higher self-efficacy scores. Observation and interview data of 8 higher and 8 lower self-efficacy sub-group students were also analyzed. The higher self-efficacy sub-group students tended to use more cognitive practice strategies, while the lower self-efficacy sub-group tended to use dissimilar and less advanced strategies. Understanding string students' musical background experiences and characteristics and the possible relationship self-efficacy may have with practice and achievement could benefit certain students. Helping these students gain a higher sense of perceived self-efficacy in their musical endeavors, or obtain certain characteristics that successful students share, could possibly enable them to develop and understand more complex practice …
- The Effects of Amplification and Selected Vocal Exercises on the Perceived Vocal Health of Elementary Music Educators.
- 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 indicated by women. The vocal problems of women may have been associated with loud voice use. The following common vocal complaints of men may have been related to the use of falsetto while teaching: need for vocal rest, worse voices in the evening, dry throats, loss of voice, obvious pitch breaks in their singing voices, pain after singing for an extended time, and limited use of their high range. VHI/MVQ scores indicated that the study participants with 21 to 39 years of teaching experience had more vocal difficulties than other participants and indicated limited use of the low range of …
