Before facing the problem of preparation for the teaching of
biological sciences in the secondary schools, there must be a
clear conception of the aims and legitimate purposes of these
sciences in the high school. We are fortunate in having the aims
of biology clearly and concisely stated by the Commission on the
Reorganization of Secondary Education of the N.E.A. ("Reorganization
of Science in Secondary Schools", U.S. Dep't. Interior, Bureau of
Education, Bulletin 26, 1920). These aims will not be considered
in their entirety but only in so far as they bear directly on the
problems that follow. Before proceeding further, for simplification
we will assume that the teacher is assigned to teach biological
sciences only. Even then the field is quite comprehensive, for
besides instruction in general biology, there will be courses of
a more advanced type, in Zoology, Botany, Physiology, and often
Bacteriology, Sanitation, or Agriculture. However, with preparation
in the fundamentals necessary for biology a teacher should be
able to conduct such courses without difficulty. Thus the problem
is sufficiently inclusive if it concerns preparation for biology
alone.
The brief literal translation of the word biology, science of
life, is full explanation of its scope. A course in the subject
is not Zoology, nor Botany, nor Bacteriology, nor Physiology—but
rather all of these in one. Biology should logically follow the
nature study of the elementary grades. The course must be so
planned that it will give the pupils the maximum of serviceable
fundamentals and at the same time be a basis for further study in
advanced courses, if he desires to continue; but such that he will
miss none of the essentials if he does not. Since science is
the product of mature minds, the culmination of knowledge, then in
this course for adolescents, the "ology" must not be too greatly
stressed lest the essential part, the "bios" be obscured. The
goal then is a course in which a study of plant life, a study of
bacteria in relation to human welfare, a study of animal life,
and the biology of the human, are all incorporated with well
balanced emphasis. This is the type of course recommended by
the Commission on Reorganization for the ninth or tenth year
pupils, so is the end toward which preparation should be made.
The next question concerns what constitutes adequate preparation
for the direction of studies of animate nature. First and foremost
is a realization of the aims, or better, the values, and relations
of biology. It is a socializing subject and must be so taught—man
is social. Biology affects man vitally, directly his behavior
follows natural laws, and indirectly by illustration and comparison
brings him to a better understanding biologic laws underlying the
organization of society. By way of illustration we need only to
cite the struggle for existence and the division of labor with
their far reaching influence in determining the course of evolution.
It would be impossible, I believe, to teach biology so poorly that
it did not have some socializing value; but it comes very near
to being done in some cases, there is little doubt.
A paramount aim is the improvement of living conditions, both
as it concerns measures for group sanitation and factors in the
health of the individual. This should be the almost exclusive aim
in those parts of the course dealing with bacteria and disease,
and the biology of man, or physiology and eugenics. Biology has
many applications in our economic life. It is the very foundation
of agriculture. The lumber industry is beginning to find that
there are biologic laws. The Government of the United States some
time ago established a Bureau of Fisheries for the purpose of
studying the biological problems involved in the continuance and
furtherance of our extensive fisheries industry.
So far as the individual is concerned, biology should train him to
observe life phenomena accurately and to form logical conclusions,
through the use of problems. This ability is a valuable asset whatever
his life work may be. Also, if it is the right kind of a course, and
well taught, it will enrich the life of the boy or girl through the
aesthetic appeal of plants and animals, and so make possible a sincere
appreciation and enjoyment of nature. In addition, the study of
biology should make clear to the pupil the important part that the
intensive study of the various biological sciences has played in the
whole marvelous scientific progress of the past centuries.
Along with these values certain relations of biology must be
well understood if it is to be well taught. These relations may
be conveniently segregated into five groups, 1) relations to
world problems, 2) to problems of the state, 3) to the community,
4) to the school curriculum, and 5) to individual pupils. To
world problems biology bears many relations, for example, it is
fundamental in the analysis of immigration problems, especially
those phases concerning health, over-population, and the probable
hereditary effects of assimilation through hybridization. State
problems of health protection, conservation of game and forests,
control of rodents and other crop pests, and others can only be
solved after gaining a thorough knowledge of the underlying
natural laws, and acting in accordance with them. How inadequate
a game conservation law of closed season, without regard to the
breeding habits of the animal concerned! Again, State regulations
regarding the care of mentally deficient, especially in the prevention
of intermarriage, must be given consideration from the biological
as well as the ethical point of view.
As we consider the smaller group unit so the relations of biology to
that group become more special. A biology course may be readily
standardized for national problems, but for any given community the
course must be somewhat unique. A course planned for a rural
population would not be fitted for a school in an overcrowded section
of a city. Where there are differences in social and biological
problems there also must be fitting adaptive changes in the course in
biology. In addition to these community relations, the teacher must
keep in mind the relations between the biology course and the other
courses in the curriculum of the school. Such a question as this
should arise in the mind of the teacher; how may my work be made to
correlate with that of Domestic Science? The possibilities are many,
there is the field of dietetics, scientific determination of the best
methods of sweeping methods by bacterial culture methods, and the role
of bacteria, yeasts and molds in the culinary arts constitute a few of
them. How about cooperation with the English Department? Certainly
every bit of written work, every oral recitation, should measure up to
standards of ability in expression as well as to standards of
attainment in the mastery of certain scientific information. This
cooperation has been carried out to great mutual benefit in some
schools. These illustrations are sufficient to illustrate, though the
teacher should not overlook any department of the school.
Relations to class and to individual will be considered in conjunction
with teaching methods.
The values and interrelations of biology have been discussed at
some length because they must serve as criteria in deciding what
constitutes adequate preparation.
The comprehensiveness and vital nature of the subject, biology,
present at once an inspiration and an element of fear to the
conscientious teacher. They cause him to regard in utter amazement,
the applicant for a position who in answer to question replies "No, I
have never taken any courses in biological Science, but I can easily
prepare myself to teach it, if need be." The impossibility of such
impromptu development of skill in the teaching of biology will become
more apparent as we proceed.
Besides a full appreciation of the aims and relations of the subject,
the teacher must be able to construct a course especially adapted in
content to the peculiar needs of the particular community. This
follows from what was said of relations in a previous paragraph. The
development of such a course demands sufficient knowledge of economics
and sociology to make possible a correct analysis of local conditions
and so find what is required. The course to fulfill the requirements
will necessarily be to some extent new, and just to such extent may
the teacher feel something of the inspiration of the pioneer. Relative
values must be established; emphasis must be properly placed—life of
distant regions should not be taught except as local material may not
be available to illustrate some very essential point, yet too often a
carefully pickled grasshopper is transported from Florida to
California, there to be dissected by some unfortunate high school lad.
Not only must the larger divisions of the course be carefully balanced
and tested for value, but each lesson must justify its induction into
it. It is at this point that the relation to the individual is the
chief criterion.
Each lesson of the series that makes up the course must
justify its place by having some rather direct bearing upon the
life of the individual pupil. The core of the lesson must be
either the pupils problem or one in which his interest can be
readily stimulated. Herein is the value of the project method
of science teaching, the problem is sure to be of interest to the
pupil since he himself chooses it. Other questions to which
the lesson must give satisfactory answer are; Why this particular
lesson, at all? What relation does it bear to the preceding and
following lessons? Is it of real value to the pupil in his living?
What biological phenomenon does it teach? Is it the best problem
to illustrate that particular phenomenon? What generalizations
and practical applications can the pupil make?
The organization of a course in biology which is fitted to
the needs of a certain community, the conditions of a particular
class of pupils, and to the needs of the individual pupils so far
as possible, requires that the teacher have an extensive knowledge
of the subject matter as a background freeing him from the necessity
of dependence on a textbook. Anyway, a biology teacher conducting
the right sort of a course, will see that the textbook is only
an incidental, if used at all. A continuation of set assignments
in most textbooks would dampen the ardor of pupils generally.
Besides, few localities have textbooks fitted to their specific
needs. One that does have is New York City. In fact it has two,
"Elementary Biology" by Peabody & Hunt, and "Civic Biology" by Hunter.
These both have a large sale throughout the United States.
But, of course, in most localities they can be used only to furnish
supplementary reading, since portions only will be adapted to the
conditions of the restricted locality. The fundamental life processes
are the same the world over, but varying environmental conditions
necessitates a variation in emphasis, in application, and in the
choice of problems which make up the course. If the teacher is well
prepared in subject matter, there is little use for a laboratory
manual except as it may suggest new methods and new experimental
materials. Students of the high school age should never be compelled
to follow a set laboratory outline with detailed instructions for
procedure; it will kill every whit of initiative. The teacher must be
so prepared, then, that he is able to steer a free course, employing
books for reference and supplementary reading almost exclusively. He
will cause the student to realize that the books are the result of
human effort and therefor not infallible, and that they must always
take second place to first hand observation and experiment. The study
of animate nature, with endless opportunity for observation and
experiment on every hand, permits little excuse for such method as is
illustrated by "Be prepared to recite on the next three pages in the
book, tomorrow, and read experiment 37 so that you wont have to waste
any time in getting started with the laboratory work".
Somewhere in the course of preparation the teacher must have
obtained a thorough knowledge of laboratory apparatus and supplies.
The selection of types of apparatus best fitted to the course, and
the knowledge of where to buy are both necessary. Also judgement
must be exercised in purchase for few are the places where funds are
adequate for the ideal equipment of a laboratory. The money value
of every piece of apparatus must be balanced against its relative
usefulness in the successful culmination of the course. Besides
this there must be a knowledge of the various uses to which the available
apparatus may be put. A great deal depends on the ingenuity of
the teacher in the adaptation of even comparatively simple apparatus.
In connection with the laboratory part (and this should be the major
part) of the course, there arises the question of field work and
excursions. Laboratory is at best merely a substitute for the
great out-of-doors, so the more work that can be done in the field
the better. Aside from exploration to discover what parts of the
particular locality will yield the largest fund of valuable biological
information, the problem here is mainly one of method.
The teacher to be at his best must be somewhat of a naturalist.
Upon his fund of interesting stories about the animals and plants
that the children all know, will depend very largely the appeal of
the work to the pupil. Something of the spirit that distinguished
John Muir as the great naturalist is an inestimable asset to the
teacher. If it is not among his natal blessings, he need not
be completely discouraged for it can be acquired to some degree at
least. Besides the advantage just mentioned, the fauna and flora
must be sufficiently well known so that choice is possible for
laboratory experiment and illustrative purposes.
In order to present any subject well, its historical aspect
enters into consideration. The influence of individuals, of
governments, of religion, and of the social ideals have all had
their share in determining the present status of the subject.
Science as it now is, is the result of growth, it has undergone
evolution, and is at present evolving. This will be thoroughly
understood by the teacher of science, and this understanding will
determine in part the method of presentation. In the history of
the development of science there are many men well worthy of hero
worship. It is hard to find more inspirational characters than
those of Pasteur, and Lazear; men who devoted (in latter instance,
sacrificed life) their lives to service for humanity. In the
life and work of Charles Darwin we find a splendid example of
painstaking search for the truth. The records of the rocks,
(Paleontology, the nature-written history of biology) will often
come to the rescue of the teacher in clearing up the presentation
of the difficult problems of evolution. The historic attitude
must be "put over" to the pupil too, for he must know his world
as the result of the evolutionary process, and as still in the
process of evolution.
Even at the risk of adverse criticism I desire to include
among the qualifications of a good teacher the spirit of research.
This spirit can be acquired by specialization in one of the fields
of biological science, followed by some actual research work.
Research in science is fundamental. It has three aims or
ends, 1) discovery of facts thus increasing the sum total of
knowledge. This is science for science sake. 2) Individual
development. And, 3) Social service. These last two aims are
most important to the teacher. So, his problem for investigation
should have some practical bearing, and should be of his own
choosing, not pointedly suggested by the professor in charge as is
too often the case. If the research student is given a problem
which is some minor part of a larger problem being investigated by
his professor it will preclude the very thing the prospective teacher
needs, namely practice in recognizing, analyzing, and solving a
problem in its entirety and solely on his own resources. Being
a mere helper is probably not the best way to secure such ability.
Investigation may be broadening and developing to the individual
or it may prove to be quite the reverse, but that lies within the
control of the individual. Research for the teacher must emphasize
equally actual additions to knowledge and personal attitude. It
must not be an end in itself but a means to an end. The attitude
of the investigator is essential to the understanding of children
for the child is first of all an investigator. His questions,
"what? why? how? when?" prove this beyond doubt. What is this but
a search for truth, causal factors, and interrelations? Education
uses this wholesome curiosity as a foundation principle, so the
teacher must exhibit a sympathetic understanding of this universal
attribute of children. No better summary of a discussion of the
values of research can be found for our purposes than that by
G. W. A. Luckey. It follows.
"In order that teaching may be intelligent and in harmony
with the laws of nature there must be a deeper and clearer
knowledge of human growth and development. The teacher must
know the nature of the individual to be taught and the ends to
be reached in proper nurture. This can not be gained through
the study of books alone, but may come through properly directed
research in the workshop of life."
One of the aims of present day education is "to develop a man, the
best man possible under the conditions; to assist nature through
nurture; to enable the individual to find himself and to evolve
naturally and rapidly to the highest levels and
even to rise above them. According to this conception ... the
initiative must come from within. The aim of the teacher should be to
develop a self-sustaining, self-directing, altruistic individual
keenly alive to the interests of humanity. Such an ideal is
progressive, scientific, and fits one through studies of yesterday and
today to live the best and truest life tomorrow. To see and appreciate
this ideal, research is necessary."
The last requirement to be considered in this discussion, is a good
foundation in Physics and Chemistry. Biological science is not
entirely separable from physical science, for a majority of life
phenomena, in final analysis can be explained only in terms of
physical science. Physiology has for its very foundation Physics and
Chemistry. Among the newest of the sciences is Biochemistry, the
chemistry of life; and within its limits are some of the most
promising fields of research. No argument is necessary, a knowledge of
physical science is indispensable in the interpretation of life
phenomena, and the understanding of biological processes.
