The Dissertation House Model: Doctoral Student Experiences Coping and Writing in a Shared Knowledge Community

Area of Science:

• Higher Education
• Educational Psychology
• Academic Writing

Background:

• PhD attrition, particularly during dissertation writing, is a pervasive issue impacting entire institutions, not just individual departments or disciplines.
• Existing models like the master-apprentice and collaborative cohort approaches have limitations in addressing the complex, cross-disciplinary challenges of doctoral research.
• The need for systemic, collaborative solutions is evident to improve graduate student retention and success rates.

Purpose of the Study:

• To introduce and evaluate the Dissertation House model (DHM), a novel approach to doctoral dissertation supervision.
• To assess the efficacy of the DHM's multidisciplinary mentoring and collaborative cohort structure in supporting graduate students.
• To empirically examine the benefits of the DHM using propensity score analysis based on a decade of student data.

Main Methods:

• The study analyzed reflections from over 200 students participating in the DHM over a 10-year period.
• It employed Thoits's coping assistance theory and Hoadley's concept of knowledge communities to frame the intervention.
• Propensity score analysis was utilized to empirically assess the DHM's benefits and effectiveness.

Main Results:

• The DHM's multidisciplinary approach effectively supports students by integrating traditional departmental mentoring with interdisciplinary collaboration.
• Student reflections indicate that challenges in dissertation completion often transcend single-discipline boundaries, highlighting the value of the DHM's structure.
• The DHM provides a successful dissertation-writing intervention, leveraging collaborative cohorts and knowledge communities for enhanced student support.

Conclusions:

• The Dissertation House model offers a scalable and effective intervention for improving doctoral student success and reducing attrition.
• Interdisciplinary collaboration and structured support systems are crucial for navigating the complexities of dissertation writing.
• Institutions should consider adopting or adapting the DHM to foster a more supportive environment for graduate students across all doctoral programs.
