This document discusses constructivism in assessment from three perspectives. It begins by explaining constructivism, noting that learners actively construct their own knowledge by building on previous knowledge and experiences. It then outlines two types of constructivism - cognitive constructivism developed by Piaget, which focuses on individual understanding, and social constructivism developed by Vygotsky, which emphasizes social interaction and scaffolding. Finally, it discusses principles of constructivist assessment, including accessing students' prior knowledge, mental abilities like thinking and problem solving, interaction tendencies, and understanding and application of knowledge. The assessment is meant to be inductive and allow for multiple perspectives and representations of learning.
