"...A valuable resource for any qualitative researcher who considers himself a constructivist. The ideas presented help make the paradigm clearer and provide inspiration for deep reflection about the importance of being open to ideas and willing to 'reconstruct' truths when new information is discovered."-Michele Repass, The Qualitative Report "Lincoln and Guba have taken great care to elaborate on constructivism and show researchers the paradigm's systematic approach. The book may serve as a foundational work in the qualitative literature, influencing constructivists to push the boundaries of qualitative research toward better understanding of the human instrument as well as toward more equitable and inclusive evaluation models .The book also offers guidance to evaluators for engaging in effective evaluation that includes all those impacted by a program or policy." --Sheila Fram, American Journal of Evaluation
