Abstract：
Objective:The purpose of this study is to explore a new teaching reform model for electronic technology practice courses in biomedical engineering (medical engineering) majors in medical colleges, based on the demand for talent cultivation in related fields in the future development of national health care. Method: In response to the problem of the lack of prominent medical engineering characteristics in the current teaching of electronic technology practical courses in the medical engineering major, a new teaching reform model of "dual guidance" practical courses is proposed, which focuses on medical engineering students as the main body, teaching philosophy based on student job requirements, and teaching method based on the application of electrical and electronic professional technology to solve practical medical problems. The achievement oriented teaching philosophy exists in the macro and micro design of the course, and the task oriented teaching method emphasizes that practical teaching in the micro design of the course is carried out with specific medical engineering tasks as the main line. Teaching objectives, teaching design and implementation, and diversified teaching evaluation form a complete closed loop, promoting continuous self-improvement of "teaching" and "learning". The article takes the design of a multi-mode neural electrical stimulator in the practical teaching of electronic technology in medical engineering as a case study to explore the characteristic practical teaching of medical engineering under the "dual conductor integrated" practical teaching mode. Results:Compared with traditional practical teaching, under the "dual guidance" teaching mode, the average score of the teaching quality of electronic technology courses is higher than 85 points. Students' enthusiasm for course learning, competitions, and medical instrument design and debugging has significantly increased, and their scores in knowledge, ability, and quality have significantly improved. Conclusion: The "dual guidance integrated" practical teaching mode is helpful in cultivating the ability of medical engineering students to use electrical and electronic technology to solve practical problems in medical engineering. It plays a positive role in students' participation in the national health and hygiene cause after graduation, and provides meaningful reference for the characteristic teaching of electrical and electronic courses in biomedical engineering majors in medical colleges.
