This study explores Saudi teachers' beliefs about STEAM education in early childhood education settings. The study sample consisted of 245 teachers working in kindergartens. The participants completed a survey comprising twelve items to elaborate teachers' beliefs toward implementing STEAM practices in their classrooms, as well as four close-ended questions to evaluate teachers' knowledge of and familiarity with the terminology of STEAM education and their professional training in STEAM-related content. The findings reveal overall positive beliefs toward STEAM education for young children and rather moderate beliefs regarding the implementation of STEAM practices. The results also reveal that teachers were somewhat familiar with the term STEAM; however, they reported limited knowledge of the integration process and basic strategies and skills needed for its implementation. The results also demonstrate that the majority of the Saudi teachers participating in this study believed they needed additional professional development and training regarding STEAM implementation. A chi-square test indicated statistically significant associations between teachers' knowledge of STEAM education and their beliefs and between teachers' previous professional training in STEAM education and their beliefs. The implications and future recommendations are also discussed.
