Nowhere is the modern scientific movement more significant than in the field of education. Until it turned its searchlight upon class room practice, educators were content to base their work upon principles which were the result of logical deductions rather than of scientific investigation and experimentation.

The investigations of the past decade have been of inestimable value in showing the weakness of such a system but they in turn, were weak in that they concerned themselves only with the product of education and ignore the processes involved. This only destroyed the old theories by showing their inefficiency, without replacing them with new ones. Fortunately, after several city school systems had been victims of the survey epidemic, the question “Why?” in regard to the findings of the surveys became so insistent that science is beginning to realize that it must not only make an educational diagnosis but prescribe proper treatment as well.

Wisdom is the principal thing; therefore, get wisdom; and with all thy getting, get understanding.-SOLOMON.

CLASS MANAGEMENT

SPECIAL CLASSES IN RICHMOND, VIRGINIA

J. H. BINFORD SECOND ASSISTANT SUPERINTENDENT OF PUBLIC SCHOOLS, RICHMOND, VA. Richmond has 19 special classes. One class is for exceptionally bright pupils; all the rest are for pupils whose mental defects make it advisable to remove them from the regular grades.

The above classes are distributed throughout the city in the following manner. Five classes are grouped into a center called the Bellevue Special School; four occupy a part of the Nathaniel Bacon School; three schools have two classes each; four schools have single classes. Our experience is that the larger the number of classes, the better the results. The most serious objection to the isolated single class is the necessity of grouping in the same room children of different mental levels.

The work of our one class for accelerated pupils is very encouraging. The teacher is assigned to a certain building and given a group of twenty children selected in the following manner. The grade teachers submit to the principal a list of superior children as evidenced by high marks. These children are given mental tests and the twenty showing the highest intelligence quotients are placed in the accelerated class. The special teacher has been able to handle two different groups in a half session, passing on to another school for the second group.

Our classes for subnormal children fall into two groups—those for border line cases (12 classes; 20 pupils to a class) and those for morons (6 classes; 15 pupils to a class). The great majority of children placed in the subnormal classes are never returned to the regular grades because of their inability to make satisfactory progress in academic subjects.

All special class teachers must have special training for their work. The majority have grown up in our system but a number came from Wisconsin, Massachusetts, New York and other states. The esprit-de-corps among this group of teachers is the best in the city system. Visits to the rooms of other special teachers are encouraged and great help is derived from the monthly meetings where our problems are discussed. Special teachers receive a bonus of $180 a year over regular teachers.

In addition to the above organization we have a psychological examiner who passes on each child before he is placed in a special class and a social worker who visits the homes of the 350 pupils in the various classes.

A most interesting experiment during the present session is the grading of the Nathaniel Bacon School on the basis of the mental ability of the 400 pupils in the school. Last June all the pupils were tested (Binet-Terman Revision) by Miss Lucille Harrison. In September, 1917, the school was
