31	An investigation into problem solving skills in calculus : the case of Unisa first year students Mugisha, Stella 02 1900 (has links) Students’ performances in mathematics in an Open Distant Learning setting have not always been impressive. An exploratory study into the problem solving skills of the University of South Africa students in the Calculus module MAT112 is being conducted using past examinations scripts between 2006 and 2009. The study re-assesses the work done in the end-of-year Calculus examinations, by both looking at the distribution of marks awarded and assigning new scores based on an assessment rubric adapted for the problem at hand. Further assessment of qualitative dimensions that is important for problem solving in Calculus is developed from the data obtained from the assessment rubric. Using factor analysis, a hesitation factor, transfer-of-knowledge factor as well as ingenuity factor, are identified in successful Calculus problem solving. The study proposes two conceptual models; the first is to guide students in solving Calculus problems while the second one is meant to assist lecturers in the assessment of students of Calculus. / Science and Technology Education / M.

32	Epidemiologic Survey of a Unique Type of Task-Specific Dystonia in Brass Musicians Wallace, Eric (Trombonist) 12 1900 (has links) Brass musicians are known to experience a performance problem that is sometimes called valsalva maneuver or musical stuttering. This problem is known to cause difficulty starting a first note, tension in the throat, and tightness in the chest. Unfortunately, the research literature lacks sufficient details for evidence-based interventions. Therefore, the purpose of this study is to characterize and define this performance problem as experienced by brass musicians. An online epidemiologic survey was developed and deployed to collect data from brass musicians who have experienced this problem in their own playing. The survey was designed to acquire data in order to characterize and define the phenomenon through a biopsychosocial framework. The survey was also designed to assess whether this problem aligns with Altenmuller's heuristic model of motor control disruptions. A diverse group of brass musicians (n = 252) participated and offered relevant details for characterizing and defining this problem. Analysis of characteristic data suggests this problem is not a form of musical stuttering. Considering these data through Altenmuller's model suggests that this problem is experienced as a spectrum of motor disruptions that can develop into a unique type of musician's dystonia. While additional research is warranted, the results of this study are applicable to brass musicians, brass pedagogues, music educators, and performing arts health clinicians. musician's dystonia focal dystonia task-specific dystonia brass musicians performance disorders performance problems valsalva maneuver musical stuttering stutter tongue tongue stopper wind players hesitation problem locking locking problem tongue chest tightness throat tension yips Altenmuller trombone trombonists epidemiology epidemiologic survey musculoskeletal neurological disorder new type dystonia performance anxiety Dystonia.

33	Analýza českých mluvených projevů nerodilých mluvčích / An Analysis of Verbal Czech Language Usage by Non-native Speakers Pémová, Petra January 2017 (has links) (in English): The work in this diploma contains an analysis of speech accuracy and fluency of Russian speaking and English speaking students of Czech language, based on case studies. For these case studies two Russian speaking students and two English speaking students were chosen to take part. The results were compared to the results of one native Czech speaker. The accuracy and fluency analysis was carried out based on the language principles of Rod Ellis. Within the accuracy analysis, the number of error free clauses and the average number of mistakes per one hundred words were measured. Accuracy of speech is examined through concrete grammatical phenomena like the usage of reflexive particle se/si and the usage of the verb to be in the past tense. The work in this diploma also considers the ability of analysed speakers to switch between language codes and to distinguish features of formal and spoken Czech language (spoken language in informal situations). The fluency of speech is studied based on the speech rate of all analysed speakers by counting the number of syllables per one hundred words. Subsequently, the number of false starts, repetition of words or phrases, the frequency of usage of parasite words and hesitation sounds were also examined. One of the diploma hypothesis is the statement...
