After a kindergarten course of this kind, books on science and technology should be gradually introduced. Here also practice, demonstration, actual experiments should precede the study of theories. It is only after the mind is well trained with the help of examples and experiments that the explanations of theories should be attempted. In our country, the reverse method is largely followed. It means wastage of time. A student passes out by mere memory work, and as memory becomes faint, his knowledge becomes nebular, leaving him in his original state of ignorance.
The study of science and technology has an educative influence on the mind, and is of far-reaching importance. It makes one a lover of truth. It creates realistic attitude to life. It is also the enemy of superstition. A scientist depends on his powers of observation, reason for his knowledge of truth. By applying his reason to observed facts before believing in anything, he acquires patience and diligence. He thus lays the foundation of true knowledge.
