SOME FAULTS IN PEDAGOGY.

BY RALPH C. HARTSOUGH,

Physics Instructor, Wichita High School, Kansas.

One of the outstanding faults of our present educational system is its artificiality. The major part of its content is unreal in its adaptableness, inside and more particularly without the schoolroom.

And one of the glaring faults of our present day pedagogy is its superficiality. We have many old time-worn premises which are false and always have been. It is just as imperative to reconstruct our pedagogy as it is our system of education. They should both be brought down to the realities of actual life as lived in the world outside the classroom.

Not only should conditions in our institutions of learning and actions be placed on a more real and practical plane but the student should be handled with the same regard and the same severity that he will find awaiting him after school days are over. We shall then not find him as a hothouse plant, withering before the new standards that are set for him, but, having weathered exactly similar blasts during his school life, he will stand strong and sure. Then instead of 80 per cent of our high school and college graduates experiencing the usual setback at their first initiation into the school of hard knocks, they will at once function and not fail.
