2. Data Analysis Technique for the Practice of the Development Product
Questionnaire was also distributed to validate the product and to revise and improve the designed syllabus model. The questionnaire consisted of two
parts; closed questions and open questions. To analyze the questionnaire results, the researcher divided into two parts; the closed questions and open questions:
a. The Closed Questionnaire
The closed type questionnaire used Likert scale. The researcher used five point scales which are Strongly Agree SA, Agree A, Doubt D, Disagree
DA, and Strongly Disagree SDA.The five point scales can be presented as follows:

formula to get mean can be presented as follows
Notes: M: Mean indicators of central tendency of the set of sources
N: Number of cases the number of respondents PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
Then, the mean was categorized into certain criteria. The criteria was determined through the calculation of the ideal mean Mi and ideal standard
deviation SDi. The formulas to determine the ideal mean Mi and ideal standard deviation SDi based on Munadi 2014 as follows:
This research also modified quantitative data conversion formula as stated by Sudjiono 2011, p. 329:

Mean as indicators of central tendency of each indicator and each aspects of required information aimed to decide what the researcher should do. The
researcher put it into four categories which helped the researcher to decide what to do with the development product. The interpretation is presented in the following
