Knowledge is constructed by humans
Learning is an active and self-directed
situated, contextual, social process
Learners’ active role and responsible for own learning
exploration, tool usage, dialogue, reflection, etc
Moderate constructivism: sensible balance between construction and briefing
Competence connection between knowledge and ability
competence- levels determined by theory and empirical tests
