|Abstract or Summary
- It is the purpose of this thesis to present a course of study in
general "Power Mechanics" which would enable the junior high school student
to understand the elementary principles of power generation and distribution,
and to appreciate the relationships of the use of power to our social order.
The course is "general" in that it includes a study of all forms of power
used by man, which naturally implies that emphasis has been placed on present
forms of power generation and consumption. The course is "mechanical"
in that the student studies the elementary principles of generation. He
manipulates and makes models whenever it is deemed advisable.
The procedure followed in the construction of this course of study
1. Analyze the uses of power by society.
2. Make a historical study of the development of power in Man's
progress through the ages.
3. Make an analysis of the characteristics of the newer courses
of study. These characteristics are included as part of the
4. Set up aim, select and organize content and method in accordance
with the newer courses of study and the general aims of education.
The following aims were set up to guide the construction of the
course of study:
First, to orientate youth with the elementary principles of power
generation and distribution and to show the relationship of power
to civilized life.
Second, to integrate the different phases of the industrial arts
program and to integrate that program with other areas of the
Third, to develop manipulative abilities which will serve as prevocational and leisure-time activities now and in the future.
Fourth, to maintain the interest of the student: in curricular
activities by helping him reconstruct the story of power and by
pointing out to him the fact that the material covered in this
course is definitely related to other subjects in his secondary
school program. Fifth, to develop an appreciation of the mechanical refinements
which are our heritage, and of the qualifications and characteristics
of the men who made these refinements possible.
In order to achieve the above aims, the following phases of the
subject were presented: man and animal power; the principle of the wheel
and axle and how it affects power generation and transmission; wind and
water power; steam power; internal combustion engines; and electric power.
The study includes only the elementary principles of these different
phases of power, for it is believed that more technical information would
be beyond the capacity of junior high school students. However, the
application of the functional principles of these different phases of
power will meet the aims stated, giving the student insight into many of
the mysteries which surround his everyday life.
At the close of each of the units, outcomes are given in an analyzed
form, making it possible for the teacher to see the relationship of outcomes
within a section; also the relation of that section to other sections
and to the aims of general education.
In addition to the general bibliography of reference material contributing
to this thesis, the course of study carries a selected bibliography
particularly useful in the teaching of such a course. A chronological
chart of significant events in the progress of power is included
as a supplement to the thesis.
It is believed that the course of study exhibits a reasonable validity,
especially in terms of its pioneering nature. The author realizes that
experimentation and evaluation will be required; that the program is too
new for a definite statement of values, and that future applications
will undoubtedly develop additional criteria for revision.
