We can apply constructivism theory to PBL and incorporate the variable likeprior knowledge,qualitiy of problems,tutor performence,group functioning and assessments in a student group. Lectures which are inspired by constructivismreflect following features e.g It should involve students in learning process,they should be encouraged asking deep relevant questions. It should help students to see relevance to their learning.Stories and topic based scenarios are helpful in introducing the topic. Encourage application of knowledge and teamwork.Design activities to engage learners into the learning material e.g solving problems in small groups or watching and discussing video clipsgeneratingexamples of concepts,advatages and disadvantages of various procedures. This theory is well applied in clinical settings.there the teacher should appreciate what students know about a topic prior to extending their knowledge. They should be encouraged to look for evidence through history and clinical examination for and against each of their hypothesis.Students should be asked to think out loudi.e comparing and contrasting their differential diagnoses. They should be asked probing questions to enhance collaborative learning,and deeper understanding of topics. They can be offered opportunities to apply their learning soon after they learni.e by grouping them or giving them individual tasks.Emphasize diverse thinking and encourage students to listen and interact with other team members and also seek feedback and input from them. Concept It is a learning theory in which learner construct new knowledge.They add or build their new experiences on top of their current foundation of understanding.The active construction of knowledge by learner is pivotal in constructivism.
