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 …

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.

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 …

The purpose of this study was to measure music performance program enrollments and course availability for educationally disadvantaged and non-educationally disadvantaged groups (grades 9-12) in Texas, and to further examine relationships which could help music educators understand the role which music performance programs play in the lives of educationally disadvantaged students. Data analyzed were collected by Texas' Public Education Information Management System (PEIMS). Educationally disadvantaged groups under consideration included economically disadvantaged, at risk (as defined by Texas Education Agency guidelines), limited English proficient, as well as Black and Hispanic students. Separate analyses were conducted for band, choir, and orchestra. Subjects included 907,327 students from 1,048 school districts.

This study investigated the effect familiarity with a teacher had on student interpretations of teacher verbal praise in seventh and eighth grade choral ensembles. A stimulus tape was constructed of 16, 30-second videotaped clips containing verbal praise of four teachers. Teachers identified their intent in the use of praise in each example. Students (n = 80) from the four choirs responded to the tape by labeling the praise in each clip as deserved or as one of three types of instructional praise (i.e., praise to encourage, to send a message to other students, or to seek student cooperation). Comparisons were made between choirs in labeling the praise. Comparisons were made also between each teacher's stated purpose in praising and the interpretations of choirs familiar and unfamiliar with the teacher. Choirs who were unfamiliar with the teacher differed from the teachers' own students in interpreting the praise: Students who knew a teacher labeled the praise as deserved in five clips, but unfamiliar choirs thought the praise served an instructional purpose. In four clips, choirs differed in their interpretations of the type of instructional praise. Students familiar with a teacher recognized their teacher's intent in praising in 12 of 16 clips. In …
