PERSONALITY AND LEADERSHIP 89

spect individual differences, to share with them in their present
interests, and to lead them to develop lasting worth while atti-
tudes. This liking for, and interest in, young people, can be
cultivated. Let each science teacher strive earnestly to cultivate
these traits.
 The principles taught by the science teacher must be reflected
in the teacher's pattern of behavior if the desirable changes take
place in the students. The science teacher's insistence upon look-
ing at all sides of a question and expecting proof before conclu-
sions are reached would seem to demand that in speech and con-
versation careful attention be given to voicing only the truth.
Derogatory remarks about pupils, or other people; the use of
sarcasm; repetition of stories, the truth of which are unknown;
reaching impulsive conclusions-all of these belie the teacher's
supposed adherence to scientific principles. It would seem that
the students could expect the science teacher to demonstrate
always calm and considered judgment and action.
 Authorities in human development assure us that personality
traits can be developed. It behooves the science teacher to study
his own personality scientifically and to set about developing
the traits and attitudes necessary for his task. Let us remember
that a student will absorb more of his teacher (good or bad) than
he will of the subject taught!
 Among the many traits and abilities which should be found
in all teachers, such as patience, cooperativeness, tact, a sense
of humor, ability to control the classroom situation, and others,
there are a few in which the science teacher should be particular-
ly strong. Some of these are the following:
 1. Skill in organizing thought.
 2. Habits of keeping things in order.
 3. Intellectual honesty (frank admission of mistakes or lack
 of information).
 4. Ability at clear and concise expression.
 5. Skill in scientific observation.
 6. A high degree of emotional control.
 7. Intellectual curiosity (an active interest in anything
 new).
