In this article, we present some core ideas underpinning research that takes a Designs for Learning (DFL) approach guided by theoretical considerations and choices, as well as by practitioners’ challenges and inquiries. These choices shape, and are shaped by, DFL’s research goals and motives, theoretical orientation, research objectives, questions, and practitioners’ participation and ethical considerations. Further, we present and discuss how DFL as a research approach compares to other design-oriented research strategies. Even if a DFL research approach shares several similarities with other approaches of inquiry, we argue that it remains primarily oriented towards knowledge areas that relate to understanding and developing learning and teaching – both in formal education and in informal settings such as museums.

Ensuring the trustworthiness of qualitative research remains a critical challenge in educational research. However, early career researchers often lack structured guidance on enhancing the credibility of qualitative data analysis. A key issue is the limited discussion on inductive approaches that support systematic theme generation and theory development. To address this gap, this study examines how two early-career researchers employed a three-level inductive methodology during their PhD studies to strengthen the trustworthiness of their findings. Using an autoethnographic approach, the study finds that this methodology deepened their understanding of participants’ experiences, facilitated the emergence of valid themes, and reinforced credibility, transferability, dependability, and confirmability. These findings offer concrete strategies for researchers undertaking similar approaches to ensure trustworthiness in their qualitative inquiry. This study also highlights the importance of equipping PhD researchers in education with strategies to navigate qualitative research rigorously, ultimately enhancing the quality of their studies.
