RESUMO
STEAM education has significant impacts on improving preschoolers' learning engagement, cognition, confidence, and innovative thinking skills. The integration of content about local culture into STEAM projects also triggers students' awareness and engagement with surrounding communities and societies. However, teachers' competencies and willingness to implement STEAM activities are irreplaceable in determining STEM projects' frequency and effectiveness. This dataset surveyed 754 preschool teachers across ten cities and provinces in Vietnam from 8 Apr 2022 to 15 May 2022. The dataset includes seven main sections: (i) Demographics; (ii) Teachers' know-how about STEAM education; (iii) Teachers' competencies; (iv) Conditions to implement STEAM projects; (v) School policies; (vi) Local culture factors integrated with STEAM projects; and (vii) Teachers' willingness to implement STEAM education.
