=Self activity of child.= We have several times referred to the activity of the child's own imagination in working over in his mind the material supplied by the teacher, and the recognition of the fact that the child's mind is not passive but active leads us to the acceptance of a principle of the most far reaching importance in all education, namely, that the teacher cannot impart a lesson unless he can get the child's mind of its own accord to seek that very knowledge that he wishes to impart. This is the wisdom of the homely proverb, "You can lead a horse to water but you cannot make him drink." We must stimulate an appetite for the mental food we wish to give the pupil even before we give it. How can this be done? =Jewish symbols and ceremonies a stimulus to self activity.= When discussing the aim of instruction in Biblical history we took a hint from the Haggadah for Passover, the reading of which was mainly intended for pedagogic purpose since it is in fulfillment of the commandment, "And thou shalt tell to thy son in that day"; we may take another hint from it in this connection. The child at table on Passover eve sees before him a number of curious objects and ceremonials to which he is not accustomed. He sees the _maẓẓot_, the _maror_, and other symbols, he also notices the reclining attitude instead of the usual erect posture, and so he very naturally exclaims _mah nishtannah_! "How different is this night from other nights!" Then when his own curiosity has been stimulated he is given the answer to his questions and the lesson has been impressed upon him. The symbols and ceremonies of Jewish life which have their origin or explanation in the Biblical narrative are excellently adapted for this stimulation of intellectual curiosity which should precede the telling of the story. A reference to the Sabbath and how it is observed might well precede the story of creation which explains its origin and significance; a reference to the Passover observances might well precede an account of the Exodus; a reference to the synagogue might precede an account of the construction of the tabernacle, etc. These serve the double function of interesting the child in the narrative and of interesting him in those things in Jewish life which the narrative helps to explain. Where an object of Jewish ceremonial life cannot be found with which to stimulate his curiosity, some other fact of his experience may be taken instead. Thus the story of Noah might well be introduced by reference to the rainbow, the meaning of which the teacher will then undertake to explain to the child by the story.
