STEAM education for preschool children is considered an educational strategy to help develop a child’s capability comprehensively according to the motto "playing by learning, learning by playing". The article investigates the current situation for preschool children between 5 to 6 years old based on the STEAM approach with 278 managers and preschool teachers in Ho Chi Minh City. Results of the surveys show that the majority of managers and preschool teachers had correct but incomplete judgments about games concept, basic characteristics, and structure of games
games objectives, the importance of games, standards, scientific basis, and game design process for competence development of preschoolers between 5 to 6 years old. The STEAM based design and organization of games is relatively new to managers and preschool teachers
therefore, it is only sometimes held at kindergartens. The difficulties that managers and preschool teachers faced were the lack of official mechanisms or policies on macro-level regarding STEAM education, and the application of game methods in teaching preschool children between 5 to 6 years old has not been exploited or not adequately invested.
