A sample of factors presumed relevant to thetime required to complete doctoral degrees (TTC) wasexplored in a survey of 154 recent graduates of NaturalScience, Social Science, and Humanities doctoral programs at York University. In addition to thevariables of gender and discipline, characteristics ofthe supervisory relationship, as well as the graduate'sfinancial situation and enrollment status, were investigated. On average, respondents took5.94 years to complete their degrees with students inthe Natural Sciences the fastest completers. Althoughthere were no significant gender differences in TTC, male graduates were more satisfied withtheir doctoral education overall and the quality ofsupervision they received (from both their supervisorsand their supervisory committees) than were females. Males were also more likely to collaborate withtheir supervisors in the preparation of research papers.With respect to financial support, respondents who wereslower completers reported receiving more years of teaching assistantships. Additionally,respondents from the Natural Sciences reported receivingmore years of teaching assistantships and researchassistantships than respondents from the other disciplines. A multiple regression analysisrevealed that the following combination of variablesaccounted for 30% of the variance in TTC: beginning thedissertation research early in the program, remaining with the original topic and supervisor, meetingfrequently with supervisor, and collaborating withsupervisor on conference papers.  相似文献

The aim of this study is to explore the research trends in the context of postgraduate programmes in the field of Educational Technology (ET) in Turkey between 1996 and 2016, and to uncover the possible factors that influence these trends from the perspective of ET faculty members. This study was informed by critical theory and employed the critical inquiry method. In the first phase, content analysis technique was used in order to explore trends in research methods and topics in theses completed in ET postgraduate programmes in Turkey. In the second phase, in-depth interviews were conducted with 11 faculty members regarding the possible influential factors. The findings of the content analysis indicated that ET research was dominated by quantitative research designs in the examined theses. Critical methods were overlooked and social, cultural, and political issues were largely silenced. The findings of the interviews showed that the factors that have been influential on ET research trends were the social impact of the research, personal interests and skills, disciplinary and departmental culture, and feasibility concerns. This study presents implications for better ET research by addressing blind spots of the field and providing suggestions for ET postgraduate students, ET scholars, policymakers and practitioners in a global context and other developing countries since the resulting trends in Turkey were found similar to international trends in the field.  相似文献
