RESEARCH METHOD
3.1 Research Design
The method used in this research was quantitative research. Quantitative
research is research collecting data using statistical data calculations. The design
in this quantitative method is a research with experimental design. This study
analyzes the effect of the independent variable and the dependent variable. The
dependent variable is the experimental research class that gets treatment from the
research.

3.5 Research Instrument
Research instrument is a tool for measuring, observing, and documenting
the quantitative data (Creswell, 2014). In this study, the data collection instrument
used two tests, namely pre-test and post-test. These results are also used to see
whether the learning model used is going well or not.
3.6. Reliability and Validity of Instruments
3.6.1. Realibility
According to Sugiyono (2018: 174), instrument reliability is a requirement
for testing the validity of the instrument. Therefore, although a valid instrument is
generally definitely reliable, testing the reliability of the instrument needs to be
done. A reliable instrument is an instrument that, when used several times to
measure the same object, will produce the same data. To find out which test is
reliable and valid, the reliability test is analyzed using the Kuder Richardson 20
formula proposed by Sugiyono (2018: 186) as follows:
st 2−∑ piqi
ri=
k
(k−1) { st 2 }
Where:
k : the number of item in the instrument
pi : proportion of the number of subject who answer item 1
qi : 1-pi
St2 : the number of variant
The value of realibility coefficient (Guilford, 1956) as he following:
0,80 – 1,00 : the realibility is very good
0,60 – 0,80 : the realibility is good
0,40 – 0,60 : the realibility is significant
0,20 – 0,40 : the realibility is low
-1,00 – 0,20 : the realibility is very low (Not reliable)
3.6.2 Validity
According to Sugiyono (2018: 173), a valid instrument means the measuring
instrument used to obtain data (measure) is valid. Valid means that the instrument
can be used to measure what should be measured. In this study, the validity test
aims to determine the accuracy of the items to measure the social environment,
organizational activeness and social competence of students.
The SPSS testing technique was often used to test validity using
Bivariate Pearson correlation (Pearson Moment Products). Product
moment correlation formula from pearsons used:
n Σ xy− ( Σ x ) ( Σ y )
rxy = √¿¿¿
Pearson Moment Products formula:
rxy = Is the product of the total amount of variable x and the total amount of
variable y
N = Is the number of data pairs X and Y
ΣX = Is total of the variable X
ΣY = Is total of the variable Y
ΣX2 = Is squared total amount of variable X
ΣY2 = Is squared total amount of variable Y
3.7 Technique of Data Collection
Data collection is an important part of conducting research. To collect data,
this study used a pre-test and post-test given to the experimental group and the
control group.
3.7.1 Pre-test
The experimental and control groups will be given a pre-test before
treatment. This was used to analyze the ability of students speaking ability interm
of pronunciation, grammar, vocabulary and fluency.
3.7.2 Post-test
The post-test will be given to students after conducting treatment using
SAVI learning model. It aims to find out the difference in their average score.
3.8 Technique of Data Analysis
Meanwhile, analysis of the results from the questionnaire used the
percentage formula suggest by Sugiono (2007, p. 43) as follows:
F x 100 %
P=
N
In whitch:
P = Result expressed as a percentage
F = The frequency
N = Number of cases
For detail explanation of the interpretation guide as follow:
Score Interval Qualification
80 – 100 Exellent
70 – 79 Good
60 – 69 Average
50 – 59 Poor
<49 Very poor
