The data gathering was conducted by the end of the even semester 20122013 Indonesian academic year in June 2013. The researcher started to meet respondents
from school to school. So, it took a month to take the data. From thirteen sets of questionnaire were distributed, amazingly all of them returned. However, there was
one questionnaire was returned remain unfilled by a respondent.
E. Data Analysis
The very first step of data gathering was distributing questionnaire to the respondents. The respondents were given a week to fill out the questionnaire
completely. The researcher came over to each respondent to explain the procedure in filling out the questionnaire although the researcher had written a clear instruction in
the questionnaire. This aims to make sure that the respondents were able to fill out the questionnaire correctly. Then, after a week the questionnaires were collected. After
the questionnaire were returned to researcher, the results then were put into the tally system as seen in the table below.
After putting all the result in tables, the researcher calculated the data to get the MEAN for each item of the questionnaire. In addition, the standard deviation was
also gained to find out whether each item was valid. In the table presented in this survey research report, it comprises the percentage of all fourth scales 1 = strongly
disagree, 2= disagree, 3 = agree, and 4= strongly agree, the Mean, and the standard deviation.
To read the table, it can be inferred from the mean of the item. If the mean more than 2.5, it means that respondents or teachers agree to the statement. In
contrary, if the mean of an item is showing less than 2.5, it means the item is not agreed by the respondents. Therefore, the researcher presented the data for each item
in two digits of decimal. It aims to see the difference one item to another more precisely.
After completing the tally sheet, the researcher then created tables based on the result of the survey. The table helps the researcher to describe the result of the survey easily.
Hence, later on the researcher will be able to analyze then discuss the result based on the diagram and the answers of the open questions.
After obtaining the result survey, the data inform of score are then presented into table in order to make the interpretation easier to elaborate. The researcher later
describes the survey result elaborately in chapter IV section one. And then, in the second section of chapter IV the researcher is discussing the survey results and
relating them with the theory in learning and material development. This discussion is aimed to get a comprehensible conclusion and decision toward textbook since the
main goal of evaluation is to make decision based on the data gathering.
Although the researcher had time constrain, the researcher successfully interviewed respondents to triangulate the data. In addition, the researcher also happened to give them
several open questions on the questionnaire. They had to write the open questions on the questionnaire sheet. While the researcher collecting the questionnaire, the researcher tried to
confirm all the answers written on the sheet by. By doing this, the researcher was able to understand the answers from the respondents comprehendingly
.
Then, all the answers of the open questions were written in a table and categorized. Hence, these data are ready to use in
the analysis to support the survey result.
