The paper also suggested that Artificial Intelligence should be incorporated in teaching and learning in schools as it helps in solving educational problems for a better society. School teachers should be trained on effective use of Artificial intelligence machine as it serves as a backbone to all the information science that enabled intelligent tutor systems.
