60 Based on the data above, we can see that the Fleiss Kappa test score for
the three raters is 0.8717. When the score of Fleiss Kappa test is more than 0.8, the score is considered as near complete agreement. It implies that the three raters
had a clear agreement in scoring the students pronunciation and then we can use these scores to compare the students‟ ability.
4.5 Results of the Data Analysis
In this section, I will present the pre-test score analyses of experimental and control groups. After that,
the analysis of the students‟ motivation questionnaire will be explained.
4.5.1 Pre-test Analysis
In this section, I will describe about the students pre-test score from the three rater before getting treatment. The first one is the pre-test score of the experimental
group. Then, the pre-test of control group using Songs and the last is the pre-test of the control group using Fidel Charts.
4.5.1.1 Experimental Group
The pre-test mean score of the experimental group, 67 , shows that the students‟
initial ability is considered as the students of average ability. Twenty seven students are included into the students of average ability, and the others are
considered having good pronunciation ability. The pre-test average scores from the three raters are varied. The highest score of the average score from the three
61 raters is 82 and the lowest score is 61. Here is, the pre-test data score of the
experimental group

Mean 67
Based on the data above, we can see that the mean score of pre-test from experimental group is 67. According to the criterion based on curriculum 2004 in
62 the previous chapter, the students of experimental group are considered as the
students of average ability. From the data of the first rater, we can classify the students into three groups. They are poor ability, average ability and good ability.
One student is included in poor ability, twenty-eight students are included in average ability and the others are included in good ability. The highest score from
the first rater is 82 and the lowest score is 59. From the second rater, we can classify the students into two groups. They
are average ability group and good ability. There are twenty-four students are included in average ability and the others are included in good ability. The highest
score from the second rater is 83 and the lowest score is 61. Meanwhile, from the third rater data, we can classify
the students‟ ability into two groups too. They are average ability and good ability group. From the third rater, there are twenty-
seven students from the average ability group and five students from the good ability group. The highest score from this rater is 82 and the lowest one is 61.
