OBSERVATION & ITS TYPES

OBSERVATION & ITS TYPES
INTRODUCTION
From the earliest history of scientific activity, observation has been the prevailing methods of inquiry. Observation of natural phenomena judged by systematic classification and measurement led to the development of theories and laws of nature’s force. Observation is one of the most refined modern research technique. Observation seeks to ascertain what people think and do by walking them in action as they express themselves in various situations and activities. It can be made progressively more scientific to meet the needs of the particular situation and observation is a fundamental tool even at the most advanced levels of science.

OBSERVATION

Observation is recognized as the most direct means of studying people when one is interested in their  overt behavior. Observation is defined as “a planned methodological watching that involves constraints to improve accuracy.” According to Gardner (1975), observation is the selection, provocation, recording and encoding of that set of behaviours and settings concerning organism “in situ’ whcih arc consistent with empirical aims.”

CHARACTERISTICS OF OBSERVATION

1)                                Observation is at once a physical as well as mental activity.
2)                                Observation is selective and purposeful.
3)                                Scientific observation is systematic
4)                                Observation is specific 5) Scientific observation is objective.
6)                                Scientific observation is quantitative.
7)                                The record of observation is immediately.
8)                                Observation is verifiable
9)                                Behavior is observed is natural surroundings
10)                           It enables understanding  significant events affecting social
relations  of the participants.
11)                           It determines reality from the perspective of observed person
himself.
12)                           It identifies regularities and recurrences in social life by
comparing data is one study with those in another study.
13)                           It focused on hypotheses free inquiry
14)                           It avoids manipulations in the independent variable.
15)                           Observation involves some controls pertaining to the
observe and to the means he uses to record data.

TYPES OF OBSERVATION

1)                Casual & Scientific observation
An observation may be either casual or scientific. Casual observation occurs without any previous preparations. Scientific observation is carried out with the help of tools of measurement.
2)                Simple and systematic observation
Observation is found in almost all research studies, at least in the exploratory stage. Such data collection is often called simple observation. Its practice is not very standardized. Systematic observation it employs standardized procedures, training of observers, schedules for recording.
3.                 Subjective and Objective Observation
One may have to observe one’s own immediate experience, it is called subjective observation. In any investigations, the observer is an entity apart from the thing observed, that type of observation is called objective observation
4.                 Intra – subjective and inter subjective observation
If repeated observation of a constant phenomenon by the same observer yield constant data the observation is said to be intra subjective. If repeated observations of a constant phenomenon by different observers yield constant data the observation is said to be inter subjective
5.                 Direct and indirect observation
The direct observation describes the situation in which the observer is physically present and personally monitors what take place. Indirect observation is used to describe studies in which the recording is done by mechanical, photographic or electronic means.
6.                 Structured and Un structured observation
Structured observation is organised and planned which employs formal procedures, has a  set of well defined observation categories, and is subjectd to high levels of control and differentiation. Unstructured observations is loosely organized and the process is largely left to the observer to define.
7.                 Natural and Artificial Observation
Natural observation is one in which observation is made in natural settings while artificial observation is one in which observation is made in a laboratory conditions
8.                 Participant and Non-participant observation
When the observer participates with the activities of these under study is called participant observation Merits:- Acquiring wide information, Easy in exchange of clear observation of neutral and real behavior. Limitations :- larger time required, greater resources required lack of objectivity.
When the observer does not actually participate in the activities of the group to be studied but simply present in the group it is common as non participant observation. The observer in this method makes not effort  to his influence or to create a relationship between him and the group. Merits:- Acquiring information with influence , maintaining impartial status, maintaining objectivity and scientific outlet.
Limitations:- Inadequate and incomplete observation, subjectivity,
Unnatural attitude of the subject matter of observation
ORGANIZATION OF FIELD OBSERVATION
For valid and useful field observation, the following steps have be taken .
1.                 Determination of the method of study ie the field observation in relation to the phenomena.
2.                 Determination of the nature and limits of observation is the preparation of a plan of observation
3.                 Decision as of directness of observation ie the relationship between the observer and the subject must be direct.
4.                 Determination of Expert investigations /Agency of field observation is the person who makes observation may be the researcher himself or the field workers
5.                 Determination of time, place and subject to study
6.                 Provision of mechanical Appliances needed in the usage of various instrumental aids like camera, maps.
7.                 Data collection, having arranged all the necessary tools and equipments need for research.
8.                 Data analysis :- The data should be analyzed and processed
through classification, tabulation etc.
9.                 Generalization :- The interpretation leading to draw general conclusion
Sarantakos (1998) has printed out the following six steps in observation.
1.                                Selection of the topic :- This refers to determining  the issue
to be studied through observations  e.g.:- material conflict, riot etc.
2.                                Formulation of the topic :- This involves fixing up categories
to be observed and pointing out situations in which cases are to be  observed.
3.                                Research design :- This determines identification of subjects
to be observed preparing observation schedule if any and arranging entry in situations to be observed.
4.                                Collection of data :- This involves familiarization with the
setting,  observation and recording.
5.                                Analysis of data :- The researcher analyze the data, prepares
tables of interprets.
6.                                Report writing :- This involves writing of the report for
submission to the sponsoring agency or for publication.

GUIDELINES TO EFFECTIVE OBSERVATION

1.                   Obtain Prior knowledge of what to observe.
2.                   Examine general and specific objective.
3.                   Define and Establish categories, each category or level of data being collected should be concisely and carefully  described by indicating the phenomena the investigator expects to find in each.
4.                   Observe carefully and critically.
5.                   Rate specific phenomena independently, using well defined
rating scale.
6.                   Devise a method of recording results ie the observation schedule.
7.                   Become well acquainted with the recording instrument.
8.                   Observers would separate the facts from their interpretation at a later time. They can observe the facts, and make interpretation at a later time.
9.                   Observations are to be checked and verified, wherever possible by repetition or by comparison with those of other competent observers.

INSTRUMENTAL AND IN OBSERVATION

Instruments such as the camera, stopwatch, light meter, audiometer, SET meter, audio and video tape recorders, mechanical counter, and other devices like detailed field notes, checklist, maps, schedules, store cards , socio-metric scales etc make possible observations that are more precise than mere sense observations. Such things are also referred as techniques of control as used in controlled observation.

PROCESS OF OBSERVATION

Observation involves three process ie sensation , attention perception. Sensation in gained through the sense organs which depends upon the physical alertness of the observer. Then comes attention on concentration which is largely a matter of habit. The third is perception which comprises the interpretation of sensory reports.
Thus sensation merely reports the mind to recognize the facts.
QUALITIES OF A GOOD OBSERVER
1.                         The observer should pocess efficient sense organs.
2.                         The observer must able to estimate rapidly and accurately
3.                         The observer must possess sufficient alertness’ to observer several details simultaneously .
4.                         The observer must be able to control the effects of his personal prejudices.
5.                         The observer should be in good physical conditions
6.                         The observer must be able to record immediately and
accurately
The observer should be a visiting stranger, an attentive, listener eager learner of a participant observer.

VARIOUS STEPS OF GOOD OBSERVATION

1.                 Intelligent planning
Intelligent planning should be needed in a good observation, the observer should be fully trained as well equipped, too many variables may not be observed simultaneously, the conditions of observation should remain constant.
2.                 Expert execution
An expert execution demands  utilizing the training received in terms of expertness, proper, arrangement of special conditions for the subject, occupying, phisical observing, focussing attention on the specific well defined activities, observing discreet keeping in mind the length, number and intervals of observation decided up on and handling well the recording instruments to be used.
3.                 Adequate recording
The recording should be as comprehensive as possible to over all the points and not miss any substantive issues
4.                 Scientific Interpretation
The interpretation made and recorded comprehensively need to be interpreted carefully. So adequacies and competencies required for this need to be present in an observer. This alone facilities a good interpretation.

ADVANTAGES OF OBSERVATION

1.                 It allows collection of wide range of information
2.                 It is a flexible technique in which research design can be modified at any time
3.                 It is less complicated and less time consuming.
4.                 It approaches reality in its natural structure and studies events as they evolve.
5.                 It is relatively inexpenience
6.                 The observer can assess the emotional reaction of subjects.
7.                 The observer is able to record the content which gives meaning to respondant’s expression
8.                 The behaviour being observed in natural environment will not cause any bias.
9.                 Superior in data collection on dependable and convincing
10.            Greater accuracy and reliability of data.
11.            Results are more dependable and convincing
LIMITATIONS OF OBSERVATION
1.                 Establishing the validity of observation is always difficult
2.                 The problem of subjectivity also involved
3.                 There is the possibility of distortion of the phenomena through the very act of observing.
4.                 It is a slow and laborious process
5.                 The events may not be easily  classifiable
6.                 The data may be unmanageable
7.                 It is going to be a costly affair
8.                 It cannot offer quantitative generations.

CONCLUSION.


Observation is a more natural way of gathering data. Every teacher has to observe his students in different situations at different times. Observation became an effective tool of scientific study when it is planned systematically recorded systematically is subjected to check and control and selected observers have skill and are trained
