The main educational goal of preschool education is to enlighten young children’s intelligence and physical fitness. It is a relatively free stage in the entire education system and has an important impact on children’s growth. Traditional language teaching activities for middle-class preschoolers often adopt the indoctrination teaching method, resulting in many children being unwilling to express themselves actively and having chaotic language logic. Gamification-based teaching activities are one of the best choices for teachers to improve the language expression skills of middle-class preschoolers. Based on this, this paper briefly analyzes the teaching value and application status of gamification-based teaching in cultivating young children’s language expression skills, and discusses the practical strategies for enhancing the language expression skills of middle-class preschoolers through gamification-based teaching.
