Exploration of the Online and Offline Blended Teaching Model in Cell Biology Experiment Courses

The Cell Biology Experiment is a core professional course in the biotechnology program. In response to the reduced instructional hours under the new talent cultivation framework and the limitations of traditional teaching models, methodologies, content arrangements, and faculty allocation, we have implemented online-offline blended teaching reforms. The instructional system has been restructured into "four-tiered hierarchy and four modular components", complemented by multiple innovative measures: developing dedicated online course resource sections, creating novel teaching methods, adopting diversified assessment criteria, integrating ideological and political education elements, and enhancing student engagement through interactive teaching activities. These initiatives fully leverage the advantages of hybrid teaching. The results demonstrate effective guidance from instructors and significantly improved student learning autonomy. This model not only strengthens students' mastery of theoretical knowledge but also enhances practical operation skills, cultivates innovative thinking capabilities, fosters collaborative spirit, and develops comprehensive analytical abilities. Notably, students' learning interest in cell biology experiments has markedly increased. Additionally, both teachers' instructional competence and educational quality, as well as students' comprehensive literacy, have been substantially elevated.
