TEACHING SCIENCE IN SECONDARY SCHOOLS


 1. To make possible first hand knowledge which is more
 educative than pictures, models, and other visual material.
 2. To stimulate interest in natural as well as man-made
 things and situations.
 3. To enable students to know their environment more inti-
 mately.
 4. To give training in careful observation.
 5. To associate science of the classroom with the natural and
 applied science outside school.
 6. To provide helpful practices and cultivate the habit of
 spending leisure time profitably.
 7. To take advantage of the opportunity to teach conserva-
 tion. (Do not denude area visited. Avoid and guard
 against developing a souvenir collecting attitude.)
 8. To arouse vocational interests.
 The school journey (field trip) should be planned well in ad-
vance. The purpose and all details of the planning should re-
ceive the prior approval of the principal. If bus transportation
is involved, the principal should make the arrangements. If per-
mission to visit an industry is necessary, the principal should
make the first contacts with the owners or managers, even if a
later request, specific as to time and number of visitors, is to be
made by the science teacher or by a committee of students. If
any private property is to be crossed by a class on a field trip,
the principal should be certain that it is with permission and
that no trespass is involved.
 The teacher should make a preliminary visit to any field or
factory to which a class journey is planned. If the chief items
of interest in a manufacturing plant are agreed upon by the
teacher and the prospective guide, the visit will be more effi-
ciently carried out.
 The school journey should always be followed by a review
such as reports, discussions, and other activities. This should be
done so that the journey is summarized and new problems set-
tled.
