E. Instruments to collect the data
In collecting the data, the researcher used observation guide, interview guide and questionnaires. Observation guide and interview guide were made to
get important information about the setting and the problem. There were three sets of questionnaires used in this study. The first one which was distributed in the
beginning of the research was made to know the learning habit and needs of the students. The other two questionnaires which were distributed in the middle of the
process aimed to obtain the data of the evaluators’ opinions and suggestions about
the medium developed. The last questionnaire was used to get the data of opinions and suggestions about the medium developed from the students.
F. Data Analysis
There are two kinds of data in this research, namely qualitative data and quantitative data.
a. The qualitative data
The qualitative data were obtained from the interview with the teacher based on the interview guide and the observation. The data from interview and
observation were about the classroom condition, the learning teaching process, the problem faced by the teacher, and the expected solutions. The comments and
suggestions from the English teachers were also described qualitatively. b.
The quantitative data To determine the feasibility of the media through the quantitative data, the
researcher used
Likert Scale
in analyzing the data. The researcher used the
Likert
Scale
to quantify the respondents’ opinion through the questionnaires. The quantitative data were obtained from the second and third questionnaires which
were distributed to the English teachers and the students. The scoring of the data used the following formula.
1 = SD, if the respondents strongly disagree with the statement 2 = D, if the respondents disagree with the statement
3 = A, if the respondents agree with the statement 4 = SA, if the respondents strongly agree with the statement
The data were analyzed by calculating the percentage by using the formula below:
Note: P= Percentage of the item
f= collected scores N=Number of cases
After calculating the percentage, the researcher transformed those percentages into criteria of feasibility. This was very important to know whether
the media should be revised or not. The criteria are as follow:
Table 2: Percentage of Feasibility Criteria Purwanto, 2000:103 Scores
Category
81 - 100 very good
61 - 80 good
41 - 60 fair
21 - 40 poor
≤ 20 very
poor
P =
� �
�
The pop-up book was considered as feasible to apply if the score is more
than 60. The pop-up book should be revised if the score is less than 60.
