Purpose: This study aims to address the complexities of fixed and growth mindsets within educational settings and critique traditional assessment methods and interventions used in mindset research. It aims to develop a comprehensive approach -- encompassing methodology, conception and practice -- that incorporates mindsets within a broader growth orientation framework. Design/methodology/approach: This research uses a holistic case study analysis of 14 higher education students, emphasizing their personal growth narratives. A uniquely designed course draws on person- and idea-centered principles that provide a rich environment to facilitate students' growth. The analytical approach moves beyond standard mindset questionnaires by integrating self-awareness, cognitive biases and personal growth factors into a multidimensional growth orientation framework. Findings: Results suggest that traditional mindset metrics may be indirectly related to actual growth orientations due to the influence of cognitive biases. This study finds that typical short, focused interventions may fail to reflect true changes in mindset, as they often do not engage with the broader personal growth orientations of the individuals involved. Originality/value: This research is original in its application of a holistic and comprehensive approach to studying growth in education. By contextualizing mindsets within enriched learning environments that promote deep reflection and knowledge building, it provides new insights into how educational practices and research methodologies can better support authentic and sustained growth in learners.
