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 purpose of this study was to identify the occupational aspirations and expectations of students majoring in jazz studies, and to investigate relationships between students' aspirations, expectations and selected variables including significant others, choice of school, instrument type, academic achievement, academic level, socioeconomic status, age, gender, and early jazz experience. All jazz studies majors enrolled at the University of North Texas during the Spring 2001 academic semester responded to a pilot test questionnaire (return rate 85%, N = 211). Frequencies, percentages, means, and standard deviations described the students' occupational aspirations, occupational expectations, backgrounds and training in jazz prior to entering UNT, and determined the extent to which parents, relatives, teachers, friends, and role models helped steer them into jazz (Pearson r, Spearman Rho and Point Biserial correlation coefficients provided). The low to moderate positive correlation between aspirations and expectations (r = 0.43) indicated that the two variables were different and measured different types of occupations. Fifty percent of students aspired to be jazz performers whereas 29.7% expected to be jazz performers. While 42% aspired to be engaged in a combination of occupational activities, 48% expected a combination of occupational activities. Only 4.7% aspired to teach; however, almost 16% expected to …
