Behaviourism is a philosophy based on the proposition that all things which organisms do — including acting, thinking and feeling—can and should be regarded as behaviors. In education, behaviourist approaches emphasise changing behaviour through rewarding correct performance.
The constructivist psychologies theorize about and investigate how human beings create systems for meaningfully understanding their worlds and experiences. In education, constructivist approaches emphasise active engagement of learners with the conceptual content through staregies such as talking (not just listening), writing (not just reading), interaction, problem-solving and other 'active' approaches.
