This self-study research aims to explore, after undergoing mindfulness training, how the researcher, serving as a university teacher educator (hereafter referred to as the educator), perceives the changes in classroom experiences and teacher-student relationships. It further investigates how preservice teacher students experienced the integration of 10-minute mindfulness activities into classroom sessions. Additionally, the study examines how the educator adjusted the design of mindfulness activities based on feedback from students and a professional development group of teacher educators, in order to deepen students’ mindfulness experiences. The researcher took on multiple roles as a teacher educator, mindfulness practitioner, and course designer, bringing mindfulness activities into the classroom and collaborating with three other teacher educators from the same college in a professional development group. Data sources included the researcher’s reflective journals, students’ learning portfolios, and meeting records from the professional development group, all analyzed using thematic analysis. Findings revealed that the educator demonstrated greater patience and presence in the classroom, rekindled enthusiasm for teaching, and reduced oppositional dynamics with students. Students reported that the mindfulness activities enhanced their emotional awareness and acceptance, stabilized their emotions, improved focus, and contributed to both their quality of life and professional growth. Based on feedback from students and the professional development group, the educator refined the activity design by strengthening the connection between mindfulness and course objectives, repeating the same practices across weeks, sharing personal mindfulness experiences, and allowing students to engage in ways that suited their individual needs—thereby enriching their experience of mindfulness integrated into the classroom.
