Teachers’ perspectives on teaching, learning, and education are their beliefs, attitudes, and understandings. This study examines Vietnamese teachers’ perspectives on constructivist theory, a “revolution in current educational psychology”. Because it has greatly influenced teaching and education philosophy and practice worldwide, notably general education program reform. This study uses constructivist theory to build techniques and forms for Vietnamese primary teachers through experiential activities. The north Vietnam: Hanoi Capital, Vinh Phuc City, Ninh Binh City, Cao Bang City, Lao Cai City, Bac Giang City. The average tenure of teachers is nearly 11 years. The authors used a teacher’s questionnaire from six provinces to collect data on constructing experiential activities in a constructivist primary school subject. The findings showed that primary teachers preferred experiential activities in the subject based on constructivist theory and that story-telling and conversation were the most popular teaching methods and instructional forms. Constructivist theory stresses that learners actively construct knowledge and understand via experience. Teachers that use constructivist theory to build primary school experiences will help kids at this foundational level acquire quality and capacity.
