Grounded in ecological systems theory, this paper argued that school refusal was a product of imbalances in systemic interactions rather than a mere manifestation of individual pathology. This counseling practice report focused on a junior high school student with chronic school refusal, comorbid emotional and behavioral disorders, and high-risk behaviors. Bronfenbrenner’s Process-Person-Context-Time (PPCT) model had been utilized for comprehensive assessment and systemic intervention. The counseling strategy departed from traditional problem-correction orientations and instead adopted a strengths-based approach, where the school counselor had integrated a cross-system collaboration network involving school, family, medical, social welfare, and community sectors. The core mechanism involved operationalizing a "culinary strengths curriculum" into key "proximal processes," which transformed the home economics classroom into a secure "transitional microsystem." The counseling process had progressed through five distinct stages: establishing a therapeutic alliance, emotional regulation and communication, strengths-empowerment practice, career orientation, and transition empowerment. Results indicated that through cross-system collaboration and the medium of cooking, the participant’s high-risk behaviors were significantly mitigated. Furthermore, attendance rates and the quality of parent-child interaction had also improved. Ultimately, the participant rebuilt self-efficacy through technical strengths and successfully transitioned to a vocational high school culinary program. The ecological systems practice framework proposed in this paper demonstrated that activity-based intervention combined with resource integration effectively assisted the student in rebuilding social connections and returning to the learning trajectory, providing a valuable reference for clinical practice.
