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.

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
r =       (1+rɪ)
          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
Mean = A+             ∑Fx       × C
                             N
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
c.      Find X1²,X2², X3²………….. and ∑X1², ∑X2², ∑X3²,…………..
d.     Correction term C =  (∑X)²/N, where N= total no. in all groups.
Step – 2
          Calculation of total sum of squares around the general mean. It is calculated by using the formula.
St² =∑X² - C
Step -3
          Calculation of between group sum of squares (Sb²)
          Sb² = ∑X1²/n1+ ∑X2²/n2 + ………….. – C
Step -4
          Calculation of with in group sum of squares
          Sw² = St² - Sb²
Step -5
St² = N-1
Sb² = K -1
Sw² = N-K

Interpretation of ‘F’ ratio
          The critical value of F ratio are 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 district.

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 study habit and achievement of Higher Secondary School Biology Students with 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.
·        There existed negligible or indifferent correlation between study habits and achievement in biology of students at higher secondary level for the whole sample and relevant sub samples – boys, rural group, aided school and unaided school students.
