Construction of a Blended Teaching Mode for Medical Parasitology in China during COVID-19 Pandemic.

Facing the challenge of COVID-19 pandemic, online education rapidly occupied the daily teaching in China, which promoted the development of “Online+Offline” (blended) teaching. Medical Parasitology majorly aims to cultivate students' basic knowledge of Parasitology and the ability of "diagnosis and control of parasitic diseases". The Massive Online Open Course (MOOC), intelligent teaching software and Parasitology multimedia laboratory are used for blended teaching. Theoretical teaching includes intensive lectures, self-learning and flipped classrooms. Practices are taught in blended manner. The most representative means is the flipped classroom integrating learning with application through “case discussion - laboratory examination - uploading diagnosis basis on line - group report for peer learning". An evaluation combining formative and summative evaluation, online and offline assessment is jointly applied. We selected Clinic Medicine major as the experimental group, the Basic Medicine, Medical Experimental Technology and Biotechnology majors as the control group. The experimental group was taught in the blended teaching mode of “combining virtuality with reality, learning with application”; and the control group was taught in the traditional mode of lectures in big group and practices in small groups. The scores of the final computer test and the final offline experimental test were used in comparison. The experiment and theory scores of the experimental group are both significantly higher than that of the control group. The blended teaching is highly recognized by our students, and the teaching mode has been widely demonstrated and recommended to other courses in and out of the university. This mode comprehensively cultivated students' basic knowledge of Parasitology, and the ability of diagnosis and control of parasitic diseases. This blended teaching mode of “combining virtuality with reality, learning with application” effectively improved students' academic performance and application abilities, and well cultivated students' thinking of diagnosis and control of parasitic diseases.
