This book addresses the challenges of computer professional education in secondary vocational schools by proposing innovative practices of diversified teaching methods. Through in-depth exploration of teaching models such as flipped classrooms, micro-lectures, project-based learning, "learning through competitions", SPOC, and OBE concepts, the work provides a detailed analysis of the teaching design and implementation strategies for core courses including "C Language Programming", "Photoshop", "Database Application Technology", "Digital Audio and Video Post-production", "Fundamentals of Computer Application", and "Computer Network Technology". These methods not only enrich teaching approaches, enhance students' learning interest and effectiveness, but also promote the cultivation of students' practical abilities and innovative thinking. The implementation of this work holds significant guiding significance for the teaching reform of computer majors in secondary vocational schools and has contributed to the supply of more high-quality skilled talents to the industry.
