A Blended Case-Based and Practical Training Framework for Graduate Ultrasound Education: A Perspective on Competency-Based Instruction.

With the widespread application of ultrasound in disease screening, clinical diagnosis, and efficacy monitoring, the traditional model in which ultrasound examinations and diagnoses are independently performed by ultrasound physicians has increasingly struggled to meet the growing clinical demands. The gradual introduction and standardized development of the professional role of ultrasound technicians have imposed new training requirements on graduate education in medical imaging technology. Against this background, how to effectively cultivate students' clinical thinking and technical operation abilities at the graduate level has become a significant educational challenge in ultrasound teaching reform. Based on the above educational needs, this paper proposes a competency-oriented conceptual teaching framework that integrates case-based teaching with structured practical training for ultrasound instruction in graduate programs of medical imaging technology. This framework is based on competency-based education theory and aims to bridge the gap between theoretical knowledge and practical operational skills. The framework systematically elaborates on principles for case selection and design, practical training content, and teaching methods, while constructing a closed-loop teaching structure of 'case introduction-group discussion-skills training-reflection and summary. Meanwhile, this paper analyzes the key issues that may arise during the implementation of integ rated teaching, including complex teaching organization processes, uneven student participation, and insufficient transformation of learning outcomes, and proposes corresponding strategies, such as standardized process design, formative evaluation mechanisms, and diversified assessment methods. From the perspectives of theory and teaching design, this paper proposes a structured teaching model to provide a reference for graduate ultrasound curriculum development and teaching reform, and lays a foundation for the further practice and validation of a competency-oriented training model for ultrasound technicians.
