The practice department of the Teachers’ College is one of its most important features, for a fundamental assumption is that practice is the key-note of all training, that no one can consider himself trained who has not taught, and that the future teacher must observe good teaching, and must teach under normal conditions. The Horace Mann School for the observation and practice of the students of the Teachers’ College comprises kindergarten, primary, grammar and high school grades. The heads of departments arrange the teaching of the students, and great care is exercised in keeping the school efficient, as the observation of good teaching is considered only second in importance to actual practice. I heard a botany lesson in the practising school, given by the instructor in methods of botany. The class, numbering about twelve children, of about ten years of age, was furnished with lenses, and needles, and a plentiful supply of flowers. Each child was required to see and examine all the flowers that were given to him, to describe carefully and exactly what he had observed, and to take nothing for granted. The methods adopted were such as to make the children original investigators, and the attitude of the teacher towards her subject was such as to develop a spirit of reverence in the children, and to arouse an interest æsthetic as well as scientific. No technical terms were used in descriptions. The botany lessons are adapted to the different seasons of the year. For example, the scheme of work for the Autumn term is:-- Autumn Flowers. How differing from Spring flowers in Colour. Size. Growth. Autumn Fruits. Their growth. ” parts. ” use to man. ” use to animals. Study of Seeds. Growth. Methods of Distribution. { Food. Uses for { Oil. { Medicine. Grain and harvesting. Observation of Trees. Falling of leaves. Colours ” ” Leaf-buds. Deciduous trees. Evergreen trees. Preparation for winter by plants. Seeds. Buds. Leaves. The herbarium is not much used, but in autumn each child and student brings a specimen of one tree or plant. All the specimens are kept and are used for the study of seeds during the winter. Twigs are brought into the school-room and made to grow in water, seeds are grown in shavings, and plants of all kinds are watched during the year.
