INDIVIDUALIZED INSTRUCTION The systems approach can be used to design instruction that will be delivered to students on an individual basis , or it can be used to design instruction that will be imparted simultaneously to a group of learner

In 1970 Seymour paper drew on Piaget ideas to create LOGO , single computer programming language that let children control the movement of a simulated turtle by giving it simple commands In 1980s and 1990 there was rise of constructive theories which advocate that knowledge is constructed by scientists experts and not discovered from the world
