Abstract This paper examines concepts of constructivism on curriculum, teaching, evaluation, role of teachers and role of students, From which we can draw significent features to apply to curriculum design. From the literature review, constructivism has two ramificatioms: radical constructivism and social constructivism. Generally, constructivism favours infinitive, undesigned curricnium and emphasizes equal responsibilities shared by teachers and students. Constructive curriculum is designed to strengthen students' hands-on experience and to allow more opportunities and time for students to think and construct knowledge. In addition, there is need to develop more tools for exploring students' cognitive growth. In short, constructive curriculum emphasizs that students should construct their knowledge on their own initiative.
