Profiles, perceptions, and practices related to customizable computer-aided instructions (MacGAMUT) among postsecondary aural-training instructors

Thesis (D.M.A.)--Boston UniversityThe purpose of this study was to examine relationships between demographic and educational characteristics of postsecondary aural-training instructors and their practices using CAI (here, MacGAMUT). Instructors who use MacGAMUT (N = 278) were surveyed about their profiles, perceptions, and practices using a pilot-tested, researcher-designed online questionnaire. Two separate four-way MANOVAs were chosen to simultaneously analyze whether respondents differed on eight dependent variables. Significant main effects were found for the whole model (p = .010), gender (p = .018), and years using MacGAMUT (p = .006) in MANOVA 1; and the whole model (p = .022), years teaching aural skills (p = .015), and years using MacGAMUT (p = .001) in MANOVA 2. Significant interaction effects included the influence of gender on monitoring student usages of MacGAMUT (p = .017), years using MacGAMUT on the impact of CAI on learning dictation skills (p < .0001), years using MacGAMUT on the impact of instructors' interactions and involvement with MacGAMUT on learning dictation skills (p < .0001), and years using MacGAMUT on the impact of customization on learning dictation skills (p = .004) in MANOVA 1; and the influence of years using MacGAMUT on the importance of requiring students to use MacGAMUT in Mastery Mode (p = .005), and years using MacGAMUT on how often students are required to submit MacGAMUT assignments (p = .011) in MANOVA 2. Conclusions focus on the instructional uses of MacGAMUT as having a positive impact on student learning of dictation, thus placing a greater responsibility on the instructor to coordinate their uses of CAI thoughtfully with the curriculum. Suggestions for further research include gender differences using more complex types of music technology, in-class practices of aural training, reasons for default changes, userfriendliness, reasons for discontinued use, professional development, graduate training in technology, foundational assumptions among Digital Natives, and a replication of the study

A Study of the Effects of Frequency Variance on Duration Perception

This study investigates the effects of frequency variance on duration perception, using musically trained subjects. In the experiment three silent duration intervals were examined (4.75, 5.00, and 5.25 seconds); each interval was preceded and followed by tone markers. The onset marker was preceded by seven discrete tones one second apart, on the frequency 174.968 Hertz. This established a pulse or an external standard time measure. The subjects made judgments as to whether the offset marker fell "before," "on," or "after," the pulse. The offset marker had a variable frequency. In the study, the direction of the frequency change, the distance of frequency change, and the mathematical intervallic relationships of the two frequencies show possible influence on duration perception

Aircraft Maintenance Organizational Structure Changes an Antecedent Model

Air Force leadership has ordered the development of an Enterprise Resource Planning (ERP) system called the Expeditionary Combat Support System (ECSS). Many current jobs and positions will be streamlined, restructured or removed, while some will certainly be created to handle the new requirements associated with ECSS. The structure of the Air Force is certain to change with the implementation of ECSS. The Air Force has used many maintenance organizational structures since its inception in 1947. The focus of this research is to analyze past organizational structures to define key factors that affect organizational change. A case study style methodology was applied to eight periods of maintenance-related organizational change. Strategic initiatives, information and maintenance-related technology advances, change and project management practices were evaluated for relational affect. The researcher found that the strongest relational variables leading to organizational structure change were force-size change, budget change and major conflict occurrence or cessation

Generative comics: a character evolution approach for creating fictional comics

Comics can be a suitable form of representation for generative narrative. This paper provides an argument for this based on an analysis of properties of the comics medium, and describes a tool for character design and comic strip creation that applies interactive evolution methods to characters in a virtual environment. The system is used to interactively create artificial characters with extreme personality traits inspired by well-known comics characters
