Educational implications of Jean Piaget's Cognitive Development 

• This theory provides broad development perspective to the teachers and curriculum designers to make a better curriculum for the children. 
• Use collaborative as well as individual activities because kids learns as much from each other as from parents or teachers. 
• Emphasis on Discovery approach in learning because child learns faster by doing this rather than hearing about them. 
• Co-curricular activities have equal importance as that of curricular experiences in the Cognitive Development of children. 
• Use props and other visual aids to support learning.
