While women have influenced the fields of program evaluation and mixed methods research, their contributions are rarely acknowledged. In this edited volume, we recognize the contributions Jennifer C. Greene made to evaluation and mixed methods, focusing on how she disrupted traditional ways methods are conceptualized and implemented. We aim to provide a range of perspectives on how Greene disrupted social science theory, methodology, and training through her commitment to the values of democracy, diversity, and dialogue. Accordingly, the volume makes explicit how Greene democratized social science inquiry and training by emphasizing inclusive, culturally responsive, and educative theories, methods, and pedagogical practices. Second, it clarifies how her commitment to diversity supported scholars from diverse disciplinary backgrounds and cultures (within and beyond the United States) and validated often ignored perspectives on phenomena or experiences. And third, it showcases how her commitment to dialogue opened spaces for non-traditional methodological approaches that engage, communicate, and disseminate program evaluation and mixed methods work. Taken together, the first-hand accounts presented in this volume offer a historical perspective and practical guidance on program evaluation and mixed methods conceptualization, implementation, and training. Endorsements: 'The theme of “disruption” in this book is a powerful look at the breadth and significance of Jennifer C. Greene’s distinguished contributions, both theoretical and practical, in evaluation for over 30 years. In essence, these chapters reveal the sustaining power of her scholarship and influence today and likely in years to come. Her recognition that no single method can solve the complex problems faced in evaluation is revealed in the ontological, epistemological, and methodological work she developed on mixed methods, which led to a genre of study that recast the debate about the hegemony of quantitative over qualitative methods and vice versa. She has foregrounded values, the quintessential character of evaluation, by recognizing the multiplicity of perspectives that guide our theories, roles, questions, designs, and perceptions of quality. Jennifer Greene’s generativity is exemplified in her egalitarian dialogic stance, inclusion of voices and context, and commitment to equity. The chapters reflect the impact of her work on scholars who continue to advance evaluation for a more just society.' — Valerie J. Caracelli, U.S. Government Accountability Office 'It is not possible to convey in a few words my strongest endorsement for this volume that begins scratching the surface of Jennifer C. Greene’s many contributions to evaluation theory, methods, and practice. I have worked with and learned from her on many occasions over the years as I grappled with refining my understanding and practice of culturally responsive evaluation. I commend the editors and authors for this first substantive collection providing a more in-depth understanding and appreciation of Jennifer Greene’s body of work for some while providing others the opportunity to revisit the lessons we have learned from her work, spirit, and commitment to make a difference.' — Stafford Hood, Center for Culturally Responsive Evaluation & Assessment (CREA) and Professor Emeritus University of Illinois at Urbana-Champaign
