Subjects of the Research Data Collection Technique

Table 6: The Organisation of Questionnaire for Expert Judgement No Components of evaluation Number of item Reference 1 The appropriateness of content 1-10 BSNP 2 The appropriateness of language 11-17 BSNP 3 The appropriateness of presentation 18-27 BSNP 4 The appropriateness of layout 28-35 BSNP There were also three open-ended questions that were delivered to the materials development expert: 1. What do you think about this unit? 2. What aspects should be revised in this unit? 3. What is your suggestion about this unit? The instruments used to collect the qualitative data were: 1. Interview The interview was done when the researcher was conducting needs analysis. The interview was conducted to the students and the English teacher. In conducting the interview, the instruments used were an interview guideline. 2. Observation The instrument used in observation was an observation guideline.

G. Data Analysis Technique

There were two types of data gathered in this research. Those data were analysed in two ways. 1. Quantitative data Quantitative data came from the questionnaires. The data from the first questionnaire which was needs analysis was analysed by calculating the percentage of each point of choice within the questions according to Suharto 2005. Then, it was described in descriptive statistic. The item which had the highest presentation was considered as the tendency of students. The second questionnaire which was a questionnaire for the materials development expert consisted of statements and responses in the form of Likert Scale. Likert scale wass a scale which was used to gain information from the respondents. It was used to indicate the strength of the materials development expert’s agreement and disagreement related to the statements given. The data from expert were, then, measured using mean central tendency and analysed using a formula proposed by Suharto 2005. The Likert Scale used in the second questionnaire uses 4 point range as follows. Table 7: Likert Scale 4 Point Range No Categories Score 1 Strongly Agree 4 2 Agree 3 3 Disagree 2 4 Strongly Disagree 1 The data from the expert was calculated by using a formula proposed by Suharto 2005:59 to find the range or the data interval. After that, the data was converted into descriptive statistic. The researcher used mean X as the indicator of measurement.
