The concepts and standards of teacher certification provide a scientifically sound approach to addressing issues such as unclear practical teaching objectives, single content, irregular management, and inadequate safeguards in preschool education programs. This approach centers on a comprehensive practical teaching system structured around “four modules and three tiers”: a content framework encompassing skill training, course-based practice, educational practice, and innovative practice; and a management system grounded in dual-mentor guidance and institutional protocols. This model offers a reference framework for practical teaching in preschool education programs at private applied universities.
