4. Techniques of Data Analysis

Data analysis technique was conducted with two techniques which were qualitative for interview, and quantitative for questionnaires.

a. Techniques of Data Analysis from Interview

There were several models of process analysis. The model used in this research is posted by Miles and Huberman 1994 which were data reduction, data display and conclusions drawing and verification. 1 Data reduction was the process of selecting, focusing, simplifying, abstracting and transforming data. 2 Data display was an organized, compressed assembly of information that permits conclusion drawing and action. 3 Conclusion drawing and verification was the process of making a conclusion from the data collected. 43

b. Techniques of Data Analysis from Questionnaires

There were three kinds of questionnaires in this research. The first were students’ profile and needs analysis questionnaires and the second were for revising the product expert judgment, and the last were questionnaires for evaluating the materials. To know the students’ profile, the researcher used the frequencies and percentage formula. The percentage is calculated by dividing the frequency of a number of the respondents and the result is multiplied by 100. The formula is shown below: � = � � � 1 Frequency Percentage Formula While P = percentage F = frequency N = total of respondents 100 = fixed number To analyze the materials review and evaluation, the researcher used descriptive statistics to describe the result. The questionnaires were in the form of scales that include four opinions which were: strongly agree 4, agree 3, disagree 2 and strongly disagree 1. To know the results or to evaluate the materials, the researcher also used descriptive statistics and the scales were divided into four which were: strongly agree 4, agree 3, disagree 2 and strongly disagree 1. Here is the formula proposed by Ravid 2011. 44 �̅ = ∑ � � 2 Mean Formula While �̅ = mean ∑x = the sum of all scores N = the number of scores The data were analyzed by using central tendency measurement to summary score that is used to represent a distribution of scores. According to Ravid 2011 there are three central tendency measurements: mode, median and mean. In this study, mean was be used to describe data that is the most representative of the data obtained. Mean, which is also called the arithmetic mean, is calculated by dividing the total sum of the scores by the number of scores. In order to know that the product developed by the researcher was good and appropriate for students, the scores were analyzed by using the category proposed by Wagiran 2015. The categories were divided into four, which were very good, good, fair and poor. Table 4: Interval Category proposed by Wagiran 2015, 337-338 No Interval Interpretation Category 1 X Mi + 1,5SD to Mi + 3SD X . �� . Very good 2 X Mi to Mi + 1,5 SD X . �� . Good 3 X Mi – 1,5SD to Mi X . �� . Fair 4 Mi – 3SD to Mi – 1,5 SD �� . Poor 45 While X = Total scores per student M ideal = highest score 4 + lowest score 1 ÷ M ideal = 4 + 1 = 5 ÷ 2 = 2.5 M ideal = 2.5 Sd ideal = highest score 4 – lowest score 1 ÷ Sd ideal = 4 – 1 ÷ = . Sd ideal = 0.5 c. Reliability and Validity Reliability and validity are the two criteria used to judge the quality of all standardized quantitative measures. Reliability referred to the consistency and dependability of measuring instruments Ravid, 2001. According to Gall, Gall and Borg 2003, test reliability referred to how much measurement error was presented in the scores affected by the test. Based on the theory, Gall, Gall and Borg 2003 reliability coefficients vary between values of .00 and 1.00. Thus, the test scores with a reliability of .80 or higher were sufficiently reliable for most research purposes and 1.00 indicated the perfect reliability of the test score. On the other hand, validity indicated the accuracy of the instruments Lodico et al., 2010. Moreover, validity also referred to the degree to which instrument measured and appropriateness. The materials validation was done by the expert judgment. Validation was judged by several aspects of materials developing. From the results, the materials were valid and can be used for the next steps of the research. 46 In order to analyze the reliability of instruments and the stage of materials evaluation, the researcher used the interval scoring proposed by Cohen et al., 2007. The interval scoring is presented as follow: Table 5: The Reliability Coefficient of Cronbach’s Alpha Cronbach’s Alpha Coefficient Interpretation . Very highly reliable . − . Highly reliable . − . Reliable . − . Marginallyminimally reliable . Unacceptable low reliability Cohen et al., 2007, 506 The reliability is used to measure the instruments whether they can be used in this research. The table shows level of reliability. According to the table, score among 0.70-0.80 means the instruments are reliable. The higher reliable is the score among 0.80-0.90. The highest reliable instruments are the score those higher than 0.90. 47

CHAPTER IV FINDINGS AND DISCUSSION

In this chapter, needs analysis was shown in the form of percentages. The syllabus and lesson plan were done in order to design instructional materials for English writing.

A. Needs Analysis Results

Needs analysis was done to obtain the information from the Second Year students of English Department, Champasak University. The data was analyzed into percentages and interpreted in order to explain the results.
