基于项目式学习的线上线下混合式教学模式在高校生物科学类课程中的应用OA

Project-based learning(PBL),as a pivotal approach to fostering students' learning capabilities and enhancing their skills,is widely adopted in primary and secondary schools and universities due to its efficacy in bolstering comprehensive literacy.Using the course biology teaching design and case analysis as a case study,an online and offline blended teaching mode based on PBL was proposed.To assess its impact on bioscience courses in higher education settings,various assessment tools were developed,including the Bio-logy Classroom Teaching Rating Scale,Pre-service Teacher PCK Level Assessment Scale and Pre-service Teacher Deep Learning Level Assessment Scale.These tools were subsequently employed to evaluate a total of 108 pre-service teachers who underwent the teaching mode implementation.The results revealed a progres-sive increase in teaching skill scores among the pre-service teachers across the initial,intermediate and fi-nal stages.Both the overall pedagogical content knowledge(PCK)levels of the pre-service teachers and their deep learning abilities were significantly improved at the later stages when compared with the initial stage.
