In the context of the digital age, this work addresses the problems of traditional teaching methods, such as the difficulty in stimulating students' interest and the lag in knowledge updates, by proposing a solution that integrates information technology with innovative teaching concepts. This work systematically introduces the application strategies of digital tools in biology classrooms, such as smart classrooms and synchronous classrooms, aiming to enhance teaching interaction and effectiveness. It first deeply analyzes the necessity of the digital transformation of teaching, then elaborates in detail on the integration and utilization methods of digital resources, and further focuses on sharing teaching design and implementation cases. Subsequent chapters gradually unfold, discussing key links such as assessment and feedback mechanisms. This work will be of great significance in promoting the modernization of high school biology education and cultivating future talents with scientific literacy and innovation capabilities.
