22 TEACHING SCIENCE IN SECONDARY SCHOOLS

The student needs to know something of the achievements of
scientists. He must know social and industrial procedures and
devices for the economy of time and effort. He should be given
an insight into many occupations. He must understand, appre-
ciate and be able to apply this knowledge to his everyday en-
vironment. The present state-adopted text, Using Science, of-
fers a satisfactory outline of areas and topic for the general
science course.
 Considering that many of these students will continue in the
high school science, the teacher may well direct the awakening
interest in the fields of specialized science, such as biology, chem-
istry, and physics.
 Demonstrations and experiments. Teaching by demonstra-
tion and experiment is an important part of general science.
Students should see the materials and processes being discussed
and should handle the things themselves. Demonstrations and
experiments help answer certain problems. The laboratory
work should accompany the classroom discussion of a problem
or a principle. The teacher should perform many of the dem-
onstrations in order to train students and to save time and mate-
rials. It is good practice to have students assist in demonstra-
tions, but such assistance should be distributed widely among
the class.
 Since students learn by LLUTIONS-
doing they should be al-
lowed to do individual ex- REPoRrf
