Drawing from the theoretical foundations of reflective teaching, culturally responsive education, social constructivism, and self-study, this collaborative self-study investigates the role of an interactive online journal in an international research collective. Each from a different country, the authors came together through a common interest in the "philosophy for children Hawai'i" approach to education and designed an online platform for journaling together. The overall objectives of the study are to examine how interactive online journaling influences international collaboration, individual research interests and goals, and personal and professional development. To analyze their journal the authors use an applied self-study research methodology that is self-initiated, improvement-aimed, and communicative. The findings reveal how journaling can create an international commons, deepen inquiry in the research process, and foster a culturally responsive approach to international collaboration. The discussion explores the impact of the authors' relationships and roles on their joint production of knowledge and elaborates the usefulness of collaborative technologies in reducing face-to-face tensions often experienced in cross-cultural collaboration. The authors explain how community, philosophical inquiry, and reflection in the context of online journaling proved to be powerful tools for culturally responsive researchers who wish to construct their own understandings of what it means to be a part of an international research collective.
