A good deal of help is given to teachers in their superhuman task. There is a kind of division of labor, by virtue of which more advanced experts prepare the schemata of instruction; basing them upon psychology, if the teaching is on a scientific plan, or on the principles laid down by one of the great pedagogists such as Herbart, for example; moreover, the sciences, such as hygiene and experimental psychology, are further invoked to overcome many practical difficulties and to help in the arrangement of schoolrooms, the drawing up of the curriculum, time-tables, etc.
Here, for instance, are notes for lessons on a psychological basis, that is to say, lessons which take account of the proper order of succession in which the psychical activities should develop in the mind of the child; by exercises of this kind, the pupil will not only learn, but will develop his intelligence in accordance with the laws governing its formation.

Object Lesson
A Candle: Education of the sensory and perceptive faculties.
Sight.—White, solid.
Touch.—Greasy, smooth.
Nomenclature.—Parts of the candle: wick, surface, extremity, edges, upper part, lower part, middle part. The candles we use are made of wax mixed with stearine. Stearine is made of the fat of oxen and sheep and pigs. Hence they are called stearine candles. There are also wax candles. These are yellowish and less greasy. Wax is produced by bees. There are also tallow candles; these are very greasy and have a disgreeable smell when burning.
Memory.—Have you ever seen a candle-factory? Have you ever seen a bee-hive? Of what are the cells of the honeycomb made? When do you light a candle? Have you ever carried a lighted candle carelessly? Did not this cause a disaster?
Imagination.—Draw the outline of a candle on the blackboard.
