Abstract: Since most of the students who choose the course have different majors and have no biomedical background knowledge, the teaching reforms were explored based on OBE theory from four aspects including teaching objectives, contents, modes and evaluation methods in view of the actual teaching situations of general education course on biomedical sensors. The expected learning outcomes of this course was defined clearly in terms of knowledge and ability, and the teaching contents with the application cases of the commonly used medical equipment in daily life was created. Also, diversified teaching modes, including multimedia, class discussions, product showcase, laboratory visit, combined online and offline teaching were adopted to build a multi-level assessment system. This reform aimed to break through the discipline barriers, improve students’ interest in learning this course, stimulate the students' subjective initiative in knowledge exploration and expand their horizons and knowledge, thereby improving the teaching quality.
