KEEPING TRACK
OF THE PREFERENCES IN WOMEN CONCENTRATED PROFESSIONS/JOBS: SCHOOL
TEACHING
(A Research in Turkey)
Abstract :
In “Humanizing Globalization” the philosophy of young
generation and their feeling of security in work life are very
important because those two factors affect each other vice versa.
For the female population, female concentrated professions/jobs
are also important because in those areas they feel safe and secure.
Therefore the satisfaction of the candidates of such professions,
when they are first employed is a motivative factor for their
future career. For this reason, the preference of profession of
young female generation and the reasons of choice become an important
issue.
Secondly, school teachers are one of the critical professional
careers in a society which is mostly female concentrated. So “Human
Security” topic, both for themselves and for the young population
they teach is crucial.
This paper presents the findings of part of a research on “Need
Assessment” of female concentrated professions. It focuses
on reasons of choice as a career, of school teaching. It studies
the priority of choice factors.
Those preferential factors can be used by:
·-- Government officials
·-- Man power planners
·-- School administrators and
· --Entrepreneurs investing in education
· --School guidance authorities and
· --The future candidates of school teaching
· --Also by responsibles who try to higher the quality
of teaching
Objective:
The main objective of this research is to find out the preferences
of candidates of a profession in making their choices. Secondly
within the interest area of this research is to see:
·-- How gender in a profession especially female population
change in percentage in time.
·-- What it means to be concentrated in a profession genderwise.
·-- To develop a model of tracing the changes in a profession
in relation to sex.
· --To see the examples of above items from Turkey.
Methodology :
Both primary and secondary sources will be used for the research.
How the female population, interested in teaching profession in
primary and secondary schools change in time will be reflected
through statistical data. This will reflect the change in the
trend of demand towards teaching. For this, data about students
choosing teaching schools, graduates and those employed will be
used.
Secondly, a field research based on primary resources will try
to find out the preferences of teacher candidates and the reasons
of preferences.
Use of :
The findings of this research will be beneficial to Human Resource
planners, human power planners, those who are working for the
motivation of teachers and to those who are trying to find out
and develop the attractiveness criteria for a profession.
AN ANALYTICAL MODEL FOR THE FOLLOW UP OF
GENDER STRUCTURE IN PROFESSIONS:
If it is for somebody’s interest to keep track of male and
female population for various reasons, one can develop various
models of analysis. One model might be as we did here. The first
step might be deciding whether to plan and then analyze or to
let – everything – go and then analyze. The objective
of the first one might be to “direct or guide” the
situations, people etc. towards a desired result. The second one,
“let- it – go” case and then analyze the situation
will show the effect of the natural tendencies. Whichever model
is used, the situation and situational analysis has to be made,
the preferences, the needs of all sides, have to be analyzed.
(Figure1)
In this paper the profession chosen is “teaching”
and only the preferences of those who become candidates by choosing
teacher training schools are searched in Turkey. The society accepts
teaching as a female profession. At first step, the statistical
analysis of traced back data will show if the society’s
supposition is true or not. The next step will define the concept
of the study and the third step will be the results of a research
on the preferences of the students in the Teaching Faculty of
Marmara University who will be called the candidates of teaching.
Concentration is a comparative situation. When one says female
population is concentrating in a profession, it might mean:
1. Increase ratio in total population
2. 50 % or more population
3. Continuous increase in either numbers or ratio etc
Sometimes after statistical analysis it can be seen that some
professions which are believed as female concentrated or simply
female work/job are not really so or vice versa.
The questions here are: in the time period how many of the candidates,
graduates and of the employed been female? What were the nations’
rate of change and in what direction. Concentration how to be
defined? Then of course comes preferences

As seen in the trend female teachers
are increasing as a percentage. However they haven’t reached
even to 50% yet. So this percentage might either be considered
as concentration or not.(Table 1)
CHOOSING A PROFESSION :
When a profession is preferred and a school (university) is chosen
to start a career, this is preference against other professions.
According to Marketing Science all disciplinary definitions of
‘preference’ are useful so, in marketing it becomes
an interdisciplinary perception. This window is of a very wide
angle and the factors effecting preferences become the multiple
variables necessary to be considered. One of the student’s
summary table of definitions of ‘preferences’ concentrates
on the disciplines and perspectives involved in the definitions.

Population In Professions Strategically

meaning of the word ‘preference’

As seen in the diagram above psychologists
emphasize attitudes, personal needs, psychological processes,
sociologists concentrate on social relationships and anthropologists
deal with environmental and cultural differences as determining
factors of preferences.
If the candidate of the profession is assumed to be consumer of
the profession, then the consumer preference of a profession is
formulated by two parameters such as; consumer variables (of candidate)
and product variables (of profession itself)
In this study the following concepts are important :Expectations
and perceptions, preferences, career, profession, security, buying
processes/bought idea, segmentation, concentration. The relationship
between all these concepts formulate the preference of a profession
or job.
Expectations and Perceptions; these are two separate but interrelated
and integrated concepts. Why it is said so, can be explained by
use of another concept: Observation
Expectations arise under certain conditions. The given conditions
might be as such: The classroom environment, the physical social
and economic conditions of a workplace, the possibility and impossibility
of being heated of the workplace, the preference of high ceiling
etc. Although conditions are given, expectations and specifically
perceptions change from person to person. For instance a house
might be ‘luxurious’ for one person but ‘average’
for another person. A person might consider traveling to Hawaii
as richness, the other has to travel around the world by a “love
boat” (Queen Elizabeth) to consider herself rich. On the
other side if you put those two people to the same plane or to
the Queen Elizabeth boat what they observe is different. When
people are choosing their professions, what they see in relation
to those professions are different. One observes the money s/he
might gain the other observes the prestige of the profession.
Most often one realizes kids who want to be soldiers, in the army
for their uniforms or street sweepers for the same reason. What
they observe in this costume, what they perceive is the brightness
of apolettes and what they expect is to be in it.
People in their perceptions of the situation usually present what
they perceive based on their:
1. past experience which means learnings due to past and present
internal and external environment.
2. education
3. family life, street they live in, rural or urban area they
are located in
4. economic conditions of their own
5. what they see with their equals
6. what they see in relation to higher status
7. what they see in relation to a lower status
The above 7 items and others show how people see and interpret
their position among others. However these definitions change
from person to person. Opinions, wants, conditionings, feedbacks
received, results experienced and various other factors affect
both perceptions and expectations. Therefore it’s natural
for preferences to be affected by expectations and perceptions
of a person. However there is no guarantee that expectations and
perceptions are always reliable. When profession is realized or
becomes functional than the satisfaction may lead to a feeling
of security or disappointment.

CHOOSING A PROFESSION IS A PREFERENCE
‘Preference’ is putting forward or giving priority
to setting to prior position in comparison to other things. It
implies ranking and an order of choice. It also implies worthiness
in the perception of the preferer. People prefer their occupation/profession
or their jobs. The jobs or work they do, besides other factors
(like experiences with the external and internal environment or
information and knowledge they develop etc. ) develop their career.
Dictionary defines the concept of career as ‘general course
of action or progress of a person through life. It says there
is moral, intellectual action, like, evaluation, development in
this selection process. This conscious or unconscious preference
process is framed and expressed outloud when one chooses the school
to go for the future earning of one’s life. While coming
to that stage, the internal and external environment with its
rules and regulations, norms and traditions, work and process
on the person to form the preference action.
In the manpower/human power/workforce
market, these preferences of individuals cause concentrated areas
of occupations/professions based on different variables like age,
gender, graduation levels and school titles etc.
However the development of such markets is not simply the end
result of the choices of work/job seeking individuals but also
of the preferences of demanding part. Sometimes the decision makers,
planners also play a great role in the development of concentrated
markets through affecting the preferences. Beliefs, subjective
values, presuppositions, as well as scientific research to find
out rational principles, to increase productivity and profitability
etc. contribute to this concentration. Examples are as such:
· Because women are caregiving they are best for the profession
of a nurse, teacher
· Because women are delicate they cannot work as engineers,
in construction business or be a porter.
· Because they have tender fingers they are better than
men in cotton yarn industry
· Because they complain less and they do not require health
services or legal applications as much as men do…
In summary: the work force market is developed by three basic
forces: preferences of supplier, demander and planner and concentration
develops out of the inter and intra affections of the preferences
of these sides/parties. Besides environment affects all. For instance
when the Ministry of Education places the women in all educational
books as a nurse but not as a genetic engineer or as a home sweeper
but not as the person who uses a male helper in the house, he
is using conditioning for the future. The same is true when the
pictures of men show heavy luggage carrier, president or director
but not a secretary; it is difficult for a man to be a secretary.
When crisis comes to a society even if there is demand in the
market in secretarial positions it is difficult for the male population
to accept the position because expected male role is different.
CHOOSING A PROFESSION IS A “BOUGHT
IDEA”
Preference is a kind of “bought idea”. This idea bought,
is a behavioristic response and goes through all the steps of
the buying process which is: unawareness, comprehention, conviction,
decision, actual buying and satisfaction or dissatisfaction after
sales. (Figure 3)
Preference made, causes the person to leave or give up other preferences.
However after the realization, personal approval, regret or relief
or ‘I would do it again’ feelings occur.
Preference is also based on expectations. Choice among alternatives
is affected by related expectations and the possibility of actualizing
these expectations. The smaller the gap between expectations and
actualization, the higher the satisfaction (success) is. Thus
the person is closer to the feeling of either personal approval
or ‘I would do it again’ situation. Therefore the
reasons of selecting (preference) a profession gains importance
for macro human resource power planning in a society which reflect
or imply cost benefit gained by the buying process.
The selling and buying process is effected by external and internal
environment of the person and also by inter and intra environmental
factors. How much of the choices is genetic or the ‘bio’
relations of the end results occurring by the attainment of the
profession is questionable. However it is rational or logical
to say that the greater the dissatisfaction in fulfilling the
expectations by the choice made, the greater the sensational and
mental health questions will be.
With this background information this paper chooses a female concentrated
area: school teaching, to see the reasons of preferences of female
population to be a teacher. In future this research may continue
as the need evaluation of candidates of school teaching.
To give a slight idea about the market in Turkey
for school teachers one can say: it develops both from private
and public sector. (see the trends in Turkey on page2)

CHOICE OF PROFESSION DESERVES MARKETING THOUGHT
In the ‘marketing management’ concept one sees four
different developmental stages of tendency evolution. One is product
orientation, the other is sales orientation. The third evolution
is marketing orientation. (Jobber and Lancaster , 12) However
this philosophy of marketing sometimes called ‘customer
orientation’ first included only the concept of outside
customer and considered only the ‘external’ customer.
Later, the ‘customer’ concept revised itself and included
the internal customers who are workers, managers and shareholders
etc. This stage, which is called ‘customer orientation’,
is the fourth evolution step.
Professions, defined as products/services, never moved to the
further stages of production orientation as mentioned above. We
say this because although sometimes the expectations of students
are given credit, macro planners of profession creators have never
given credit to all customers (internal and external) based on
a wholesome research. What the reflections show as a given need
of a society are: following the world tendencies, student and
parent expectations, business world expectations but not the expectation
and satisfaction of profession selectors. Of course this is one
of the reasons of the movements of human resources also. International
or national migration or job changes occur with the expectation
or satisfaction search of profession selectors.
If profession/job is the product/service, teachers are the internal
customers or in a different way the inputs which will guarantee
the production effectiveness and efficiency (of students or of
coming generations) In the marketing of products/services (meaning:
product/service development, differentiation, selling and researching
at each stage) the decisions take into consideration product attributes,
branding, packaging, labeling and product support services, in
general.(Kotler; 1994, 281-283) In literature product quality,
product features, product design are considered as the product
attributes.
If profession is the ‘product’, then one has to be
talking about product features and product benefits as the composition
that is bought.(Table 3) This is the ‘purchasing package’.
The teacher (customer of the profession) is buying the composition
or the benefits and features of the teaching profession when s/he
chooses the profession. The chooser is buying because s/he is
paying for that profession and rather than choosing other alternative
professions. S/he is deciding on this purchase.
Concrete examples of product/service features and benefits can
be seen in the following table. (Table 3)
Table 3: Product Feature and Customer Benefit Examples
| PRODUCT FEATURE |
CUSTOMER BENEFIT |
| · Automatic defrost refrigerator |
· Easiness of work, time saving |
| · Visual mobile telephone |
· You don’t loose time for looking for a
telephone booth.
· You see who is calling you, therefore message
effectiveness because of face to face communication
· It helps you not to feel homesick. |
| · Automatic gear car |
· Comfort
· Easiness of driving
· Time saving |
| · Profession of teaching(how much modern or classical) |
· Production effectiveness and efficiency
· Developed generations and developing of others
by these generations
· Knowledge and skills expected to be gained
· Wage and salary expected |

Product support services think and meet the needs
of customers. At this point a continuous research to rank the
customer needs and expectations is important. Among professions
the ones which provide services to satisfy the needs of profession
selectors will gain competitive advantage. If we give examples
from turkey the extensive management trainee programs of the banking
sector to newly graduates, before they choose and employ the needed
human resource, in the second half of 1990’ s which really
was a training program of masses were the attractiveness criteria
of the sector.
Another one was the possibility of having the chance of joining
the education and training programs abroad. Some companies from
different sectors offered those as promotional factors. Summarizing
and adapting the above information to teaching profession: branding,
labeling, packaging and product support services will be listed
as such:
Branding:
Gaining importance of teaching departments (majors) in the society
or in the world
Of science in time
Labeling: Majors in teaching,
preschool, science, physics, foreign languages etc.
Packaging: Curriculum of
teaching schools
School facilities
Side benefits of being a teacher
Product Support Services:
Education and training programs pre and during employment.

Preference of choosing a profession form the product
features. As seen in Table (4) the first priority is given to
hopelessness (no other choice). A very close reason is the expectation
of job security. Then love of children, mission, direct effectors
and work security comes. Product features and expected customer
benefits reflect themselves in the expectations and preference
reasons of a profession.
The field research with 276 teacher candidates in Marmara University,
in teacher training Faculty resulted with 218 workable questionnaires.
That means %79 of the sample population. The profile of the sample
age is not taken as a variable because it is considered to be
in the same interval. However, grade was important because a face
to face interview show the change of ideas during the education
years. So students from different grades are included. What we
are actually concerned with are the items and explanations showing
the preference reasons. Although an open ended questionnaire.
The Table (5) shows the results. The reasons of preference groups
are detailed as to y-the statements of candidates.

As seen above the reasons of preference reflect
natural needs and high expectations. However there might be contradictory
arguments to the stated reasons. The following Table (6) will
give examples to those.
Table 6: Table Of Contradictions In The Field Research Findings
| Stated |
Contradictory Arguments |
| 1 – Fit for women |
Statistics imply a greater percentage as men |
| 2 – Work guarantee |
Not in fact after graduation. They have to go through a
series of procedures like a central exam or assignment by
State. |
| 3 – Work security |
Yes but after being assigned to State schools. Private
sector puts extreme burden on teachers like related to
· Working hours
· Variability in job definition
· Formal and informal, written and verbal or unstated
expectations, etc. |
4 – A comfortable profession because:
-Working hours are limited
-Administrative responsibility is limited
-Vacation period is long |
But:
-You take work home like reading papers or getting prepared
for lessons
-Other responsibilities to the child parent, society, state
are high
-In fact that is for students because teachers go through
seminar or take office work in vacation periods. |
| 5 – Satisfactory working place |
Not satisfactory depends on the organization |
| 6 – Prestigious |
A relative concept compared to other professions because
if the individual’s prior value is income (money earned)
then other professions govern. |
Professional preferences of the young generation are closely related
with the ‘Human Security’ concept and via this concept
it is also closely related with the national security. First of
all professional preferences are made with the intention of satisfaction
(Maslow’s motivation factors). Starting from the primary
need satisfaction up to self-realization and actualization the
gains of a profession has to create this personal and individual
security. If the majority of the population feels safe and secure
about their preferences (of course built by macro human power
planning policies also) and live this security, then it is easier
to step to understanding global security.
Profession means, possibility of work
possibility of good and guaranteed earning to live
possibility of realization
expectation of satisfied and happy life etc.
The above factors mean feeling of security. Therefore if a profession
is the product/service or idea offered, then the demand has expectations
when preferring which is implied in the preference factors (reasons
of preferences). If this profession is teaching, the reasons of
choosing and their fulfillment become more important because this
market will educate and train the coming generations. They will
take prior role in EFA pathways. One has to guess what will happen
for instance if the future teachers are pessimistic, under stress
or in depression and with no aspirations. Besides if this profession
is mostly preferred by female population and if the environment
sees it fit for a female the slightest dissatisfaction causes
drastic synergistic negative effects projected to the whole society.
Form the point of view of the ‘empowering women’ orientations,
women concentrated professions have to be closely traced and those
professions have to be firstly under critical analysis. Consumer
preferences should be analyzed in relation to consumer and product
variables. Secondly perceptions of security of consumers based
both on individual physical/biological and individual mental health
and national security, based on contemporarily qualified and satisfied
population have to be integrated and logical.
