About This Book
In a sense this is a do-it-yourself, understand-it-yourself
manual. It is not a programmed text, but it will guide you, step by step, in planning and
designing a research project, however large or small it may be. This is a practical
manual, born from years of teaching research methodology to both graduate and undergraduate
students and from observing, after the course was over, all their doubts and uncertainties in the
face of a practical research undertaking. Many knew the theoretical aspects of research
methodology thoroughly, yet they had difficulty planning a practical research project, preparing
an acceptable proposal, or writing a research report. This may have been because the
practical base under the theoretical structure was not as supportive as it should have
been. Perhaps students had merely done lip-service to research, learning the essentials and
proper orientations to theoretical methodology, without coming to grips with the mundane
considerations that every researcher must learn if he is to get his project off the ground.
The types of uncertainties are many. Some students are not
sure precisely what research is; others do not know how to go about finding the information they
need. There are those who are terrified by statistics, and there are those who cannot get a
proposal accepted or secure approval for the project they have planned. In these days of grants
and financial assistance for research of all kinds, it is particularly important to know, when the
need arises, how to present one's ideas for maximum effectiveness.
Many a student has labored over a research project, whether in
high school or at the graduate level, only to be told by some instructor after all is done and much
energy has been invested that "this was not quite what he expected of the student." Such a
reaction is frustrating, comfortless, and unrewarding. To save you from such situations, this
book has been written.
The word practical is perhaps the most significant
word in the title. The practical approach means planning the project properly. It means simple,
clear, pragmatic hints on how to get the job done. It is down-to-earth guidance from those who
have traveled the road before you, who are aware of the pitfalls and are willing to share with you
the wisdom of how to avoid them.
The author of this book does not undervalue the importance of
a theoretical approach to an understanding of research. Many times it is basic and required. But a
theoretical base
ix
is not supportive enough for the practical needs of many students who must get their research off
the launch pad of theory into the orbit of creativity. For this, theoretical methodology alone
simply does not provide sufficient thrust!
One of the unique features of this book is the "Practicum in
Research" section, a part of the end matter. Here, as you pass important milestones in learning
the nature of research and how to plan it in the text section of the book, you structure your
own research project or test your understanding of the basic concepts presented in the
text. A high school or college student using this book should be able to write better term papers
or research project reports. Similarly, a graduate student should be able to construct an
acceptable proposal in a professional manner for his thesis or dissertation committee. Anyone
using it should be able to produce a superior research proposal or final document, because he
knows precisely what he is doing with respect to research and the demands it makes upon the
researcher.
The author is indebted to so many for so much of this book
that he refrains from mentioning any one in particular. To his own teachers who, during his
doctoral study, gave him the first insight into the need for a book such as this, he pays much
respect and acknowledges himself forever in their debt. Next, he wishes to acknowledge with
humility the students who, again and again, have begged him to set down for others what they
have found to be most helpful in the seminar sessions they have had with him. The same
encouragement has come from faculty colleagues in several universities. Those with whom
he has discussed the idea and who are engaged in professional research have also encouraged
setting down some of the material in this book in'permanent form. One esteemed colleague put it
in these words, "Tell them the obvious; it may be what no one else has ever thought of telling
them!" That is what the author has tried to do. The obvious is frequently so obvious that we feel
it is unnecessary to direct the,student's attention to it. To those of us who know, the nature of
research is so obvious it needs no explanation; the basic reference keys to the library are so well
known, we need not tell others about them; the reading of a statistical formula is so simple, we
would never think of teaching one who doesn't know what the secret is; a proposal is so
commonplace, we would never consider giving explicit instructions on how to write one. All
these matters are so very obvious!
Perhaps it is at the very point of the obvious where students
lose sight of what we feel there is no need to tell them. This book is an attempt to restore
academic sight to those who see either with dim vision or, as in the case of many, with none at
all. And our first exercise in seeing will be to try to glimpse what research really is.

1 What Is Research?
Research is a very confusing term.
As commonly used, it has so many meanings that we must
understand precisely what we mean when we use it in its scholarly sense. We shall discuss in
this book what is commonly referred to as basic or pure research.
Much that is said about basic research will also be applicable
to the many pragmatic varieties of research activity: applied research, action research,
developmental research, and so on. The difference between the pragmatic forms and the basic
form of research lies in the depth to which basic research probes the underlying causes and
meaning of observed phenomena and in the sophistication with which it demands that the
collected data of observation be interpreted.
WHAT RESEARCH IS NOT
To understand more readily what research is, we should begin
by considering what research is not. Some of the statements that follow may come as a
distinct shock to the conventional way in which you have accepted the meaning of the term
research. The reason for your surprise may be in part because you have been conditioned
to the term in so many connotative frameworks that you may not be sure exactly what the term
really does mean. Hence, when many students encounter the term for the first time in a truly
professional and academic sense, it bewilders them.
To illustrate, let us take several instances in which the term
research is used with entirely different meanings. For example, a housewife reads an
advertisement and learns that because of "years of research" a new miracle product has been
developed which she may now find on the supermarket shelf and which will make her
housework easier, do the job faster, and give her more time for other activities.
Her husband, on the other hand, thinks of research in quite a
different context. He identifies research with fact-finding surveys of consumer buying power,
figures showing customer preferences and needs, charts and graphs detailing company growth
and sales improvement, and, in general, the facts and figures representing the corporate
economy. This
3
RESEARCH AND THE TOOLS OF RESEARCH
information comes to him through "market research" which the "research analysts" of the
company make available to him.
His twelve-year-old son goes to school and the teacher sends
him to the library to find the names and the sizes of Columbus's three ships and also their route
across the Atlantic. In so doing, she tells him that he is going to the library to do "research" for
his history assignment.
His sister in high school has just completed a "piece of
research" by writing a "research paper" on the role of the dark lady in the sonnets of
Shakespeare. She has, of course, gone through all the motions of the "research" process by
gathering her information on note cards, collecting a bibliography, and footnoting her statements
in prescribed form. Furthermore, both she and her teacher seem quite serious in thinking of this
as a "research project."
Unfortunately, many students have labored under the false
impression that looking up a few facts and writing them down in a documented paper is
research. Such activity is, of course, nothing more than fact finding and fact transcribing. No
amount of transfer of information from one place to another, even though the act of
transportation is acknowledged by footnote, can be dignified by the term research.
Transfer of information, transportation of fact from one place to another, is simply that, nothing
more! Yet the strange misconception that fact transferral is research persists; and, even more
disconcerting, it grows in magnitude as the student progresses through the formal learning
structure from grade school to college and even from college to graduate school. What goes on
in the grades and throughout high school, bearing the misnomer of research, is further magnified
and encouraged during the undergraduate years in college. The deception is enhanced at the
college level by a more glorified terminology. Fact transportation in college is frequently exalted
by calling the end product a "research report" or a "research document." Report, perhaps; and
document, maybe-but research? Not at all.
The net result of all this is that the student becomes more and
more deeply imbued with false concepts and incorrect conditioning. The student has never been
taught; rather, he has been permitted to go unwittingly on his way without ever learning the true
nature of research. He has never learned the distinguishing characteristics which differentiate
true basic research from spurious fact accumulation.
When, therefore, this student comes to graduate study and is
faced with his first course in research methodology or a seminar in basic research design, he is
frequently unprepared for the discrete and unfamiliar demands that an entirely new academic
discipline may make upon him. As a result, he may have a difficult time in fulfilling the exacting
demands that writing a thesis or a dissertation requires of him. Consequently, he may give up in
despair, or else, after many attempts, write such a mediocre final document that his graduate
committee capitulates, despairing of ever getting a piece of real research from such a
student.
All this is the result of the student's never having been taught
the demands of pure research. Such students are unprepared to conceive of research as a discrete
academic discipline. They have never learned the particular way of thinking about facts, not as
ends in themselves, but merely as components in a total process whose ultimate aim is to reveal
their significance in the quest for the discovery of truth.
WHAT RESEARCH IS
Having discussed at some length what research is not, let us
consider what it is. Successful research begins with a proper orientation. It is essentially a way of
thinking; it is a manner of regarding accumulated fact so that a collection of data becomes
articulate to the mind of the researcher in terms of what those data mean and what those facts
say.
4
WHAT IS RESEARCH?
Many students need to understand the implications of these statements. They need to see clearly
the characteristics of what for many of them is an unfamiliar procedure. Research is simply the
manner in which men solve the knotty problems in their attempt to push back the frontiers of
human ignorance. We shall discuss these characteristics in the order in which they appear
logically in the research process.
Characteristics of Research
Research has seven discrete characteristics which appear
sequentially. Every researcher is familiar with these steps, which taken together comprise the
particular approach to the discovery of truth which we call research.
* Research begins with a question in the mind of
the researcher. Man is a curious anim:. Everywhere he looks he sees phenomena which
arouse his curiosity, which cause him to wonder, to speculate, and to ask questions. He discovers
situations, the meaning of which he does not comprehend. By asking relevant questions man
creates a favorable attitudinal climate, an inquisitive receptiveness to pertinent fact which is a
basic prerequisite for research itself, for research arises from a question intelligently asked in the
presence of a phenomenon that the researcher has observed and which puzzles him. By asking
the right questions the researcher finds both relevance and direction in his quest for truth.
Look around you. Consider the unresolved and baffling
situations that compel you to ask, "Why?" "What's the cause of that?" "What does it all mean?"
Here, for example, is a familiar real-life situation: two children begin school from the same
neighborhood; both are in the same classroom and have the same teacher. One learns to read and
progresses well; the other has great difficulty with reading. Why? What do we really know about
human learning and the reading process? What do we not know about human learning and the
origin of reading disability in the early grades? These are questions that reveal man's need for
knowledge. They are also questions that suggest departure points for research, for through
research we can discover the answers in the light of the facts. Research, thus, begins with a
questioning and inquisitive mind in the presence of baffling and perplexing fact.
* Research requires a plan. Research is not
hoping naively that somehow, in some way, you will discover fortuitously the facts that you need
or the truth that you seek. It is not aimless, undirected activity: merely "looking something up" in
the hope that you may come across" the solution to your problem. Research, rather, entails a
definite plan, direction, and design.
The whole research process should proceed purposively from
the awareness of the need to know to the point where the relevant facts speak to the researcher,
giving him the answer. And between these two extremes there must be a clear statement of the
research problem, a development of hypotheses, a design for gathering and interpreting the data,
and finally a test of the hypotheses and an arrival at factually based conclusions. Research is,
thus, an orderly procedure, - planned and logical in design.
* Research demands a clear statement of the
problem. Successful research begins with a clear, simple statement of the problem. The
perplexing and unanswered questions that the researcher finds indigenous to the research
situation must crystallize at the very beginning of the research endeavor in a precise and
grammatically complete statement setting forth exactly what he seeks to discover. The reason for
this is obvious: before we begin we must understand the problem and look at it objectively. We
must see clearly what it is we are attempting to research. We shall say more about the research
problem in a later chapter, but the necessity for a concise statement of the central problem that
the research aims to solve cannot be overemphasized.
* Research deals with the main problem through
subproblems. Most researchable problems have within them various other problem areas of
lesser breadth and importance.
5
RESEARCH AND THE TOOLS OF RESEARCH
Because many researchers take neither the time nor the trouble to isolate the lesser problems
within the major problem area, they find their research project becoming poorly defined,
cumbersome, and unwieldy. From a practical standpoint, therefore, it is more expedient to divide
the main problem into appropriate subproblems, all of which when resolved will result in the
solution of the main research problem.
To illustrate: University X has been a fast-growing and rapidly
changing institution for the past three quarters of a century. Originally conceived as a graduate
school with a major emphasis on the social sciences, it has changed direction and emphasis over
the years. Now University X is quite a different institution from that which its founding fathers
envisioned. Underlying any educational institution is a basic philosophy, a fundamental
orientation to the educational milieu in which it exists. A student wishes to determine the basic
educational philosophy of University X. Nowhere is this stated explicitly. It is implicit, however,
in the history, the structure, the policies, and the way in which the university operates. Moreover,
the cumulative result of past events has been responsible for a significant change in direction of
the university. Looked at in total perspective, the central issue begins to blur. We can perhaps
bring matters back into focus and deal more effectively with the main question of the
educational philosophy of University X by considering first some lesser aspects, or subproblems,
of the main problem:
- What was the original educational philosophy of the founders and early
administration of the university?
- What major events have caused a change in that philosophy?
- What is the present educational philosophy of the university?
These three lesser problems, answered in terms of data derived
from documents, addresses, university publications, and similar sources will provide an answer
to the principal problem.
* Research seeks direction through appropriate
hypotheses. Having stated the problem and the attendant subproblems, the subproblems are
then each viewed through logical constructs called hypotheses. An hypothesis is a logical
supposition, a reasonable guess, an educated conjecture which may give direction to thinking
with respect to the problem and, thus, aid in solving it.
Hypotheses are a part of our everyday experience; we employ
them in the approach to everyday problems. They represent the natural working of the human
mind. Something happens. Immediately you attempt to account for the occurrence by a series of
guesses, postulates, logical deductions. In so doing, you have been hypothesizing. For example,
you flip the switch of your car; the starter grinds; but the car does not start. Here you have a
problem for "research." What's wrong? Why doesn't the car start? You now begin a series of
reasonable guesses as to the cause of the trouble. In other words, you hypothesize several
possibilities:
- You have no gasoline in the tank.
- The spark plugs are worn out.
- Moisture has condensed in the distributor cap, causing a short-circuit.
Each of these assumptions provides direction in seeking out
the facts to determine the real reason why the car will not start. At this point you go in search of
the facts. You check the fuel tank: it is half full. That rules out hypothesis 1. The motor has just
been reconditioned, and new spark plugs were installed. That invalidates hypothesis 2. You
glance out of the window of the car. You note that the other automobiles have condensation on
them from the humidity and early-morning fog. Hypothesis 3 may lead you to
6
WHAT IS RESEARCH?
the solution of the problem of your stalled car. To test this hypothesis you remove the distributor
cap, wipe out the moisture that is indeed there, and replace it. The car starts. Hypothesis 3 is
supported.
Similarly, when you are faced with a problem for research,
you make educated guesses to assist you in discovering the solution and in giving you direction
in looking for the facts.
* Research deals with facts and their meaning.
Having now isolated the problem, subdivided it into appropriate subproblems, and posited
hypotheses which will suggest the direction in which the facts may lie, the next step is to collect
whatever facts seem to be pertinent to the problem and to organize them into meaningful
aggregates, capable of being interpreted. We shall suggest methods of such organization in a
later chapter. Facts, events, happenings, observations are in themselves merely facts, events, and
happenings-nothing more. They are, nevertheless, potentially meaningful. Frequently, however,
the significance of the data depends upon the way in which the facts are seen, the manner in
which the data are regarded. Often different researchers read entirely different meanings from
the same set of data. And, for the researcher, there is no single rule which will guide him
unerringly to one "correct" interpretation. Two historians may study the same series of events.
Each may be equally competent, both scrupulously honest in their reactions. One may read the
meaning of the facts of history one way; the other, viewing precisely the same facts, may arrive
at an entirely divergent interpretation. Which one is right? Perhaps both are, or perhaps neither
is.
There was a time when we considered that clocks measured
time and yardsticks measured space, and in one sense they do; but we further assumed that time
and space were two separate and discrete entities. Now we regard both of these factors
differently and deal with them within a more sophisticated concept called the time-space
continuum. The facts of time and space have always been the same. The difference between the
earlier and later concepts is not in the facts themselves, but in the increased keenness of insight
that the researcher has had into their meaning.
* Research is circular. The research cycle
begins simply: a questioning mind is confronted by a perplexing situation. To see his target
clearly, the researcher isolates the central problem for research. This central problem is then
further divided into subproblems, each of which is an integral part of the larger whole, and all of
which collectively comprise the principal research problem. What we have been calling the
environment out of which the researchable problem arises is more appropriately called the
research universe,1 and it is potentially fact-laden. The researcher seeks from
within the universe for those particular facts which seem to be pertinent to the solution of the
problem and its attendant subproblems. His search is facilitated by the construction of tentative
hypotheses. They point in the direction of relevant facts. The collected facts are then organized,
analyzed, and interpreted for the purpose of discovering what the facts mean. Such discovery
aids, in turn, in solving the problem; and this, then, satisfies the question which gave rise to the
research originally. Thus, the cycle is completed. Such is the format of all basic research.
Schematically, the "circle of research" might be represented by
the diagram on p. 8. This diagram may be thought of more as a helix than as a circle. In the
helical process of solving problems, we create still more problems; consequently, research
continues progressively onward. To see research in this way is to invest it with a dynamic
quality-a far cry from the common view of research as a static, end-in-itself matter.
1 The term universe is perhaps better understood when it is
looked at in terms of its elemental meaning. It means simply an "area" surrounding the problem
which may contain facts relevant to the problem. Literally, the word signifies the factual area
that revolves around the central inquiry, or main problem of the research. The word derives from
unus, "one," and vertere, "to turn": that which turns or revolves around one central
inquiry.

RESEARCH AND THE TOOLS OF RESEARCH
THE RESEARCH PROCESS
Practical Application
This book is more than a theoretical discussion of research and
its methodology. In addition to the discussion-which is a very practical, grass-roots,
"how-to-get-it-done" approach-this manual will provide you with an opportunity to apply those
matters that have been discussed. It will provide you with an opportunity to go into the field and
to observe research and to evaluate it. These applications of principle to operational research
practices will be given in a special section at the back of the book.
We learn to do by doing. You become a researcher by
engaging in those activities which provide training in the discipline of basic research. However,
at the very outset you should be able to recognize research when you see it. You should also be
able to recognize what is not research but masquerades as research. Turn, therefore, to, p. 218,
where you will find directions for surveying some research studies and evaluating them in terms
of the guidelines suggested in the foregoing pages.
