The study habits and achievement of
Higher Secondary School Biology students of Thiruvananthapuram District.”
METHODOLOY
Introduction
Methodology occupies a very important
position in any kind of research, as the validity and reliability of the
finding depend upon the methods adopted. The procedure adopted by the research
worker for the realization of the objectives of the study is called
methodology. The credibility obtained in research depends very much upon the
credibility of the method used. Regarding the importance of the methodology,
Barr(1960) says “ the vehicle of research cannot perform its function with out
it, since it is methodology which lays out the way in which formal research is
to be carried out and outline the detailed description of the research vehicle
and procedure.” Various steps of the plan of attack to be adopted in solving a research
problem. There are different kinds of methods and tools. The decision about the
method and tools to be employed depend upon the nature of the study under
investigation.
The
methodology adopted for the study has been described under the following heads
;
1. Method used for the study.
2. Variable used for the study.
3. Sample selected for the study.
4. Tools used for data collection.
5. Collection and consolidation of data.
6. Statistical techniques employed for
the analysis of data
Method Adopted For The Study
The
aim of the present study is to find out the study habit and achievement of Higher Secondary
school Biology Students. In the present study
Normative Survey method was used for the collection of relevant data. According
to John W. Best (1968), “ The normative survey method is concerned with the
condition or relationship that exists, practices that prevail, views or
attitudes that are hold process that are going on and the effect that are being
felt or trends that are developing.”
A
survey has been widely used in educational research for many years and continue
to be used to gather information about prevailing conditions. Survey method is
adopted by the investigator for conducting the present study. The survey method
helps the investigator to determine the present trends and solves current
practical problem. It gathers data from a relatively large sample. It suggests
a course for future development and contribute to the advancement of knowledge.
The survey method investigate phenomena in their natural settings.
Variables Used For The Study
Best
& Khan (2008),” Variables are the conditions or characteristics that the
experimenter manipulates control observes.”
The
dependent variables are the conditions or characteristics that the experimenter
manipulates or controls in his or her
attempt to ascertain their relationship to observed phenomena. The
development variables are the conditions
or characteristics that appear, disappear or change as the experimenter
introduces, removes or changes independence variables. The variables of the
study were categories as follows ;
Dependent Variable
Achievement in Biology
Independent Variables
Following
different dimensions of study habit were taken as the independent variables,
1. Time management
2. Concentration & memory
3. Studytids & Note taking skills
4. Test strategies & test anxiety
5. Motivation & attitude
6. Reading & selecting main idea
7. Writing skills
8. Study environment
9. Test taking and preparation skills.

dependent and independent variables involved in this study.
Sample Selected For The Study
The
most important study in the selection of the sample. It is imperative that a
suitable representative of the population be selected to ensure validity for
the results arrived at. The process of sampling makes it possible to draw valid
inferences or generalizations on the basis of careful observations or
manipulation of variables with in a relative small portion of the population
(Best & Khan , 1995). The most important factor that determines the
dependability of any research finding is the efficiency of the sample used for
collecting the research data. The present study
was conducted on a representative sample of 540 students of Xlth
Standard selected by proportionate stratified random sampling technique. While
selecting the sample due representation were given for the following categories
of Higher secondary school population,
1. Sex of the student ( Boys,Girls )
2. Locality of the schools (Rural,
urban)
3. Type of management of schools (
Private, Govt. & Unaided )
The
details of the schools selected for the study and breakup of the sample of
students are shown in Table 3.1 and 3.2 respectively.

Tools Used For Data Collection
For
the present study the investigator required the collection of data relating to
variables study habits and achievement in Biology. The following tools were
used in the study ;
(1) Questionnaire relating to the study habits.
(2) An achievement test in Biology for XI
standard students.
Description of Tools
Questionnaire on Study habits of Higher Secondary School
Biology Students
Questionnaire
relating to study habits was used to measure the study habits of Higher Secondary
School students. The test covering the following
dimensions of study habits.
1.Time management
2.Concentration &
memory
3.Studytids & Note
taking skills
4.Test strategies &
test anxiety
5.Motivation &
attitude
6.Reading & selecting main idea
7.Writing skills
8.Study environment
9.Test taking and
preparation skills.
Development of Tools
The
development and standardization of the tool include the following steps.
Collection of Statements
As
a preliminary step for the preparation of the tool for the study the
investigator went through the literature related to the area under
investigation. Investigator googled the internet and referred the websites
related to multiple intelligence and gathered ideas. A few statements were
prepared, verified, analysed, categorized and modified to a test battery as per
the suggestions of the guide. The test consists of 50 items representing the
components of the study habits. All the
item selected were arranged in a random order.
Screening of The Statements
The
tool was then submitted to guide and experts to judge the suitability of the
items. As per suggestions of the experts the draft form of the tool was then
printed.
Sample For Tryout
After
finalizing the format of the Questionnaire for study habits the investigator
conducted a pilot study. The pilot study was administered in order to check the
adequacy of the test and to find out the administrative difficulties. The test
was administered to 60 Higher Secondary School students in Govt. H.S.S. Pettah, Trivandrum.
The Draft Tool And Its Administration.
The
subjects were met in their classroom after obtaining permission from school
authorities. The statements related to study habits were given into the tool.
Each statement had 3 choices viz, Always, Sometimes, Often. Students were
instructed to read each of the statements carefully and answer them by making a
tick (ü) mark on the respective column for each statement of
the questionnaire. Sufficient time was given to the students in order to
respond properly.
Instruction For Scoring
The
statements were rated on a three point scale. In case of an item depicting good
study habits a score of three was given for a response always. A score of 2
& 1 was given for a response of often and some times respectively. For a
statement depicting bad study habits, the score was assigned in reverse order
that is 1,2,3 for always, often, sometimes respectively. Scoring was done with
the scoring key provided in the manual. High score on the inventory indicates
good study habits and vice versa.
Item Analysis
For
the item analysis of the tool(study habit) the Anastasi and Urbina (2003). The
procedure for item analysis were :-
Ø First the total answer scripts (60)
were arranged in an ascending order on the basis of total scores obtained by
the students.
Ø The upper 20 answer scripts were
placed in the upper groups(U) the middle 20 answer scripts were placed in the
middle group(M) and lower 20 answer scripts were placed in the lower group(L).
Ø The investigator tallied all the correct
responses to each item given by students in three groups.
Ø The discriminative power of each item
were found by subtracting the number of group from the answered it correctly in
the lower group from the number answered it correctly in the upper group (U-L).
Ø Difficulty level of the item was
obtained with the same data by adding the number of each item in all three
criterion groups (U+M+L).

Validity
The
scale was found to having both face validity and content validity. The term
face validity means that a test looks
valid particularly to those who were in the field. The face validity of the
present scale was determined by submitting it to a panel of experts. According
to them the test can measure the components of study habits experienced by the
subjects. Validity of the test is determined by correlating the total score of
study habits on a sample of 60 students. The obtained correlation is…….
Reliability
Split
half method was used to find out the reliability of the scale. This method had
been generally found by researchers and there
for odd even items were scored separately and these two sets of sores
were when correlated showed the ‘r’ as……… When adopted the Spear man Brown
formula for reliability coeffient of the whole test was found to be ……….This
shows that scale possessed high reliability.
The test is found to be both reliable
and valid for measuring study habits of standard XI in the Thiruvananthapuram
district.
An Achievement Test In Biology for XI Standard Students
Achievement
in Biology were measured using a test developed by the investigator in
collaboration with her supervising teacher.
Procedure
For The Construction & Standardisation of The Test
In
the construction & standardisation of the test, the following steps were
adopted;
1) Planning The Test
2) Preparing The Test Items
3) Establishing Validity And Reliability
1) Planning The Test
The
test was intended to measure the achievement in Biology of XI standard students
with this view a test of achievement in Biology was developed by the
investigator in collaboration with her supervising teacher. Decision was taken
to measure the instructional objectives Knowledge, Understanding &
Application and giving equal weightage
to each of them.
2) Preparing The Test Items
Preparation
of the test involved in the area of objectives, content, form of questions and
difficulty level. All the item were written in such a way that it would measure
the specified achievement in biology. For doing this a careful study is made by
referring the most widely used textbooks and the recommendations of the
supervisor and the school teachers. Weightage to objectives, Content, Form of
questions and difficulty level of items were decided and a blue print of the
test was designed.

Preparing the Test Item
When
the instructional objectives and content for a standardized achievement test
have been clearly formulated, the writing of the test items begins. The preparation
of test item involves the writing of items that directly measure the
instructional objectives and content given in the blue print.
The
investigator prepared 50 questions for the achievement test under the guidance
of the supervisor and experienced school teachers. All the questions are clear
and written in simple language. The investigator also prepared a scoring key to
make the scoring of answer paper easy.
Evaluating The Test
The
validity, reliability, practicability and objectivity were established.
Validity
A
test poses validity to the extent that it measures what it claims to measure.
The scale was found to be having face validity, content validity and construct
validity. The term face validity means that a test look valid particularly to
those who were in the field , the face validity of the present scale was
determined by submitting it to a panel
of experts. The content and construct validities of the present test were
ensured by giving representation to the prescribed content and also by ensuring
that items were developed for each subset in terms of the instructional
objectives. The statistical validity of the test were assessed by comparing the
marks obtained for the test with an external criterion viz the marks obtained
for the mid term examination. The validity coefficient obtained for the total
test is
Reliability
Reliability
refers to the consistency of measurement. That is how consistent test scores or
other evaluation results are from one measurement to another. Here the split
half method is employed to find out the reliability of the achievement test.
The test is first divided into two equivalent halves and the correlation was
found for these tests. The division had been done by separating the odd
numbered item and even numbered item. Marks obtained by student for odd
numbered item and even numbered item were found out separately. Then the
correlation was found for this half
tests by using Pearson’s Product moment correlation. Thus the reliability
coeffient of the half test was obtained as …… The reliability of the whole test
was estimated from the formula
2rɪ

Where,
rɪ = the reliability coeffient of the half test.
r = the reliability coeffient of the whole
test.
The split half reliability coeffient
of the whole class is ………..
Objectivity And Practicability of The Test
A
test is said to be objective if it is free from the influence of subjective
elements like personal bias, favoritism and the like. Since the present test
contains only multiple choice questions there was no problem of subjectivity.
In
the present test, simple and clear instructions are given for administrtering
the test and hence it is practical to
use.
Collection And Consolidation of Data
The
investigator acquired her self with the test manuals of the different test to
be administered. She then obtained copies of the test booklets in adequate
numbers. Space was provided in the test for entering the identification data
and supplementary data regarding sex, locality of the school, nature of the
school management, etc.
The
achievement test as well as the questionnaire for students on study habit were
administered in the schools selected by the investigator during forenoons. The
investigator had made arrangements with the authorities of schools selected for
testing. Then tentative break-up of institutions helped her to identify the
specific schools to be covered to yield the required sample. The type of
school, location, nature of school management and the class division to be
tested, etc. were fixed before the commencement of testing. The co-operation of
the principal and teachers of the school has helped the investigator to
administer and to test the students.
The
investigator administered the test to all the students with the help of the
teachers of the respective institutions. The service of teachers were secured
for helping the investigator in test administration. The students were given
clear instructions as to the tasks expected of them , entering the general
data, marking their responses in
questionnaire on study habits , marking the correct options given for each
questions. In the achievement test an answer sheet provided to them the time
allotted for the achievement test ,etc. before the commencement of the test
sessions. A short interval of ten to fifteen minutes was given between the
questionnaire on study habit test and the achievement test. Time stipulation,
methods of administration, etc were strictly observed.
The following steps were invariably
followed for administering the test;
1) Distribution of the test booklets to
the subjects together with printed, instructions regarding the test.
2) Explaining the general directions in
the booklet.
3) Distribution of response sheets with
institutions to filling them up.
4) Making the students familiar with the
answer sheets made of entering responses, etc.
5) Clearing the doubts of subjects
giving instructions regarding limit, method of dealing with eventualities, etc.
6) Strict adherence to the time limit in
the case of achievement test.
7) Giving intervals between testing.
8) Collecting back the booklets and
completed answer sheets corresponding to the each test.
Scoring of the answer sheets was done
by the investigator following the procedure suggested in the respective test
manuals. Scoring keys were used to expedite scoring. The scores obtained for
the different test and other details were tabulated and consolidated on data
sheet. Descriptive data like sex, location were entered in the sheets by making
them with the help of appropriate numbers. The data collected were entered in
such a way that they could be calculated manually. The calculation of
correlation coefficients, critical ratios etc. were calculated.
Statistical Techniques Used For The Analysis Of Data
Statistical
techniques helps a lot in the research work. The qualititative data can be
quantified and these can be analysed and interpreted with the help of
statistical techniques. The statistical techniques used in the present study are given bellow.
Narrative Statistics
Graphical
representation, measures of central tendency like mean, measures of dispersion
like standard deviation was used for the study to analyze and classify the data
separately.
Conclusive Statistics
Conclusive
statistics is something that helps the investigator to decide that all the
informations collected were connected with the situation and can provide with
necessary information. Various conclusive statistics like t-test, ANOVA, Duncan’s test and
correlation analysis were used for the analysis of the data conclusively.
1.Mean
It
is the simplest but most useful measure of central tendency. It is nothing but
average. It is possible to depend as the sum of all the values of the items in
a series divided by the number of items. It is represented by the symbol ‘M’ (
Mangal, 2009)
2. Standard Deviation
It
is the square root of the average of the squares of the deviations of each
score from the mean. It is regarded as the most stable and reliable measure of
variability as it employ the means for its computation. Often called root mean
square deviation and is denoted by the Greek letter sigma (Mangal, 2009).
3.Graph
The geometrical image of a set of
data, which enables the investigator to think about a statistical problem in
visual terms, pictorial representation of data is more effective than the
representation in words. Graphical representation proves quite an effective and
an economic device for the presentation, understanding statistical data
(Mangal, 2009).
4.‘t’-Test
It
is based on ‘t’ distribution and is considered as an appropriate test for
judging the significance of a sample mean or for judging the significance of
difference between the means of two samples in case of small samples. When
population variance is not known, we use variance of the sample as an estimate
of the population variance (Kothari, 1996).
5.‘F’-test
‘F’-test
is based on f-distribution and is used to compare the variance of the two
independent samples. This test is also used in the context of Analysis of
Variance (ANOVA) for judging the significance of more than two sample means at
one and the same time ( Kothari, 1996).
6. Coefficient of Correlation
Correlation
is the tendency of two or more groups or series of items to vary together
directly or inversely. Coefficient of Correlation is an algebraic method of
measuring correlation. It is a numerical value shows the degree or the extent
of correlation between two variables (Potti, 1997).
Thus
the collected data were tabulated and codified. The codified data was analysed
by using the above said statistical techniques for interpreting properly. The
analysis and interpretation are discussed in the next chapter.
Statistical Equations
Mean

A = Assumed mean
N = Total no.of Scores
C = Class interval
F = frequency
X = Score
Standard Deviation

F = frequency
X = Score
N = Total no. of Scores
Pearson’s Product moment Coefficient
of Correlation
The
formula for finding the correlation coefficient is :

Where , r = Correlation coefficient
N = Size of the sample
= Sum of X scores
∑Y = Sum of Y scores
∑X² =Sum of squares of X score
∑Y² = Sum of squares of Y scores
∑XY = Sum of product of X & Y
Test of Significance for correlation and Interpretation of r
Correlation
coefficients are interpreted by deciding whether the index is statistically
significant or not. Test of significance for a correlation was applied against
the null hypothesis. The method suggested by the Gilford was used for the
purpose. The significance was tested by finding out whether the absolute value
obtained r exceeds 1.96/√N
or 2.58/√N for significance at 0.05 levels and
0.01 levels respectively. If the correlation is significant , the correlation
was interpreted using the following techniques,
Verbal Interpretation
Correlation coefficient is given an accepted
verbal description, depending upon the range with in which it falls. For this
the verbal classification suggested by Garret was accepted.
r from 0.00 to ± 0.20 indifferent or negligible
correlation
r from 0±0.20 to ±0.40 low correlation present but slight
r from 0±0.40 to ±0.70 substantial or marked relationship
r from 0±0.70 to ±1.00 high relationship
Test of Significance for Mean Difference
In
order to compare the mean scores of each of the components like gender,
locality, type school management , level of achievement of the data obtained
had to be subjected to Test of Significance for Mean Difference. The ‘t’t test
suggested by Guilford was used for this purpose. Accordingly, the standard
error of the difference of means compared were obtained by the formula

S1 = Standard deviation of the first
group
S2 = Standard deviation of the second
group
N1 = Sample size of the first group
N2 = Sample size of the second group.
For a two tailed test if the ratio fall
between -2.58 and 2.58 it is treated as not significant at 0.01 level, but
treated as significant if the critical ratio fall outside the ±2.58. For any
critical ratio which is not significant the noticed difference are treated as real, but caused by
experimental errors.
Analysis of Covariance
The
ANOVA is an effective way for finding the difference among two or more groups.
Step -1
a. Arrangement of table to find some
initial values
b. Find ∑X1, ∑X2,…………………… grand sum ∑X

found in a f table which indicate the critical value necessary to test the null
hypothesis at selected levels of significance. If the groups differ
significantly it is essential for further the analysis of data using one of the
post hoc analysis.
Analysis And Interpretation
Introduction
Analysis
and interpretation of data are two major steps in the process of research.
Analysis is the heart of research report.
“
Analysis of data means studying the organized material in order to discover the
inherent facts. The data are studied from as many as angles as possible to
explore the new facts.” – ( Kaul )
Interpretation
is as broad as research itself and is inseparably interwoven with many other
research processes. Interpretation of data emphasizes the meaningful logical
and critical examination of the facts obtained after analysis.
“
Interpretation means an adequate exposition of the true meaning of the material
presented in terms of the purpose of the study being reported.” – ( F.L.Whitney
)
The
present study is aimed to find out the relationship between study habits and
achievement of higher secondary school biology students of Thiruvananthapuram

Method Used For The Study
The investigator has adopted a
normative survey method to conduct the study.
Sample Selected For The Study
The study will be conducted on a
representative sample of 540 Higher Secondary School Students attending
Standard X in the school
of Kerala selected from
nine schools in Thiruvananthapuram district. Proportionate stratified sampling
technique with adequate representation given to categories like gender, rural
urban , government, aided and unaided difference have been used in obtaining in
the sample.
Tools Used For The Study
The tools used for the study are ;
1. Questionnaire
for study habits
2. An
achievement test in Biology
Scope And Delimitations of the Study.
The investigator observed
maximum precautions to make the study as
prices and objective as possible. However the investigator could identify a few
limitation which are:
1.
The study was confined to
Thiruvananthapuram district due to limitations in time.
2.
Only certain study habits were tested
towards Biology.
3.
Even though XIth and XIIth standards
comprise Higher Secondary School stage in Kerala, in the
present study only XI standard students were taken as representative sample.
4.
Due to lack of time the sample size was limited
to 600.
However it is hoped that
inspite of these limitations the findings of the study will be useful to educators, teachers, parents and students
in deciding upon a wholesome programme that will facilitate better teaching-
learning process.
Statistical Teqniques
used for The Study
The analysis of the study was done using the following
statistical techniques ;
1. Mean 2.
Standard deviation
3. Graphical
representation 4. ‘t’-test
5. ANOVA 6.
Coefficient of correlation
Major Findings
Major
findings of the present study are summarized and presented below:
Ø There exists very strong positive
correlation between the study habit and achievement of higher secondary school
biology students of Thiruvananthapuram district.
Ø There exist significant difference in
the mean scores of the study habits and achievement of higher secondary school
biology students with respect to the variable Gender.
Ø There is significant difference in the mean scores of

regard to the variable – Locality.
Ø The study habit and achievement of
higher secondary school vary significantly under the didifferent type of
management of schools.
Ø There exists significant difference
in the mean scores of study habit and achievement of Higher Secondary School
Biology Students with regard to the their level achievement.
Ø There exists significance of difference in the mean scores
of study habit and achievement of Higher Secondary School Biology Students with
regard to the their family status.
Implications of The Study
The conclusions of the present study have
certain implications for developing and improving educational practices of the
today. The study reveals the associations between achievement in biology and
the study habits. Since all these are important from the point of view of
educational practices. The teachers must identify all the type of study habits
in their students. Teachers should consider all type of intelligence as equally
important. The children in their environment should be encouraged to search and
find the knowledge. The academic learning and psychological adjustment are
intrinsically related. Learning occurs only when the child is free from fears
and anxieties.
The present study reveal the existence of
direct positive relationship between the achievement in biology and the study
habits of the students. Thus having a proper study habit is the one of the
important factor in learning science. Absence of proper study habits may result in
comparatively less achievement in biology. The learning of science can be made
more meaningful by making it more process oriented. This can be accomplished by creating awareness in students
as well as their parents about importance of
proper study habit and the relation it is having with the
achievement.
The
various dimensions of study habits viz, home environment and planning of work
reading and note taking, planning of subjects, habits of conclusion,
preparation for examinations, time managements, general habits and attitudes
Social and total adjustments. School environment also had a significant
positive relationship with the achievement. This indicate the necessity of
having a properly planned study habit
giving due importance to each of its dimensions. By proper analyzing study
habits of individual students, the teachers in collaboration with the parents
cam improve the study habits.
The study habit components, preparation for
examinations note taking and leading , school environment and habits of
concentrations best predicts the achievement in biology. These factors should
be given stress while planning the study habits to improve the achievement.
Suggestions For Further Research
Based
on the conclusions derived some suggestions are given so that more studies may
be conducted on the following areas ;
1. The present study was confined to a
representative sample of higher secondary school pupils. It is there fore
suggested that similar studies can be conducted in lower primary , upper
primary , secondary and vocational higher secondary levels.
2. Similar studies can be conducted in
other subjects also.
3. A more comprehensive study habit inventory
can be developed.
4. Influence of other personality and
socio-family variables on the achievement can be studied.
5. The study can be conducted to find
out the influence of socio- psychological variations on biology achievement.
6. Since the study was confined to
representative sample of Trivandrum district only,
it is suggested to replicate the similar studies to other district of Kerala.
Conclusion
The
above findings have led to arrive at varied conclusions regarding the present
study. The study revealed that all components of study habits are closely
related in biology.
