CHAPTER III RESEARCH METHODOLOGY
A. Research Design
The aim of this study is to find out the relationship among visual learning sty
le and parents’ attention to English language achievement, therefore this research is a correlational study, which
belongs to quantitative research and a survey design.
On the research there are three correlations tested. First, correlation grips between visual learning style and English
achievement. Second, the correlation detains between parents’ attention
and English achievement. Third, the correlation clutch between visual learning style and parents’ attention with English achievement.
To have clear description about this research design, here is the illustration:
C1 C3
Notes: C2
C1= correlation 1
C2= correlation 2 C3= correlation 3
B. Data Collection
The datacollected in this study are: a. Questionnaire
The questionnaires was administered for students grade five, it is to gather information about the students data in their learning style
and their opinion about their parents attention. The questionnaire is Visual learning
style X1 English
Achievement Parents’ attention
X2
38 closed questionnaire, The questionnaire is written in Bahasa
Indonesia to ensure complete understanding of items by participants.
b. Documentation The documentation is students’ score in the test given. The test is also
used in final test at the school. C. Data Analysis
1. Instrument analysis
a. Validity and reliability Test Validity and reliability test used in this study is to measure the
instrument validity and reliability. It is valid and reliable if accepted with the indicators used in the variables. Validity means the
individual’s score from instruments is meaningful also can be interpreted and concluded from the sample while reliability in this
study means the instruments’ score run stable and consistent. To know the reliability of instrument, it is done a tryout to 25 students of SDN
Cempaka Baru II grade V.
Validity test used r- critics 0.21 with statement ― the
questionnaire is valid if 0.21 and not valid when 0.21.‖. While reliability test used r-
critics 0.6 with statement ―the questionnaire is reliable when 0.6 and not relia
ble if 0.6‖. To measure the validity of the instrument the writer use Pearson Product Moment

, the following is the formula:
n∑XY - ∑X ∑Y rxy = ______________________
√ n.∑X² - ∑X² N.∑Y²-∑Y² Note :
rxy : Correlation coefficient
N : Number of respondents
x : Distribution of student who gain learning experience
y : Distribution of students outcome

39 ∑y
: Total score of students outcome ∑xy : Total number of x multiple by y
x² : Guarded from x
y² : guarded from y
To examine the reliability of the instrument this study use
the formula AlphaCronbach: nS²-
∑Si² α = ___________
n-1 S² Note :
α : alpha coefficient
n : amount of respondent
S² : variants total of score
Sі² : variants of item.
2. Technique in Data analysis This study used Pearson analysis in analyzing the data, then for the
purpose of testing hypothesis, this study also analyzed: a. Normality test
Normality test is to find out whether the data distributed normally or not. To measure normality test following procedures are done:
1. observation Xı, X

, …
Xn be zı, z
2
,…
z
n.
2. each this raw numbers using the standard normal distribution list, then calculated the odd F zi = P z zi
3. then calculated the proportion of z1, z2…zn smaller or equal to zi by S zi then S zi = number of z1, z2…zn smaller zi equal to
the amount of data shared. 4. compute the difference F zi
– S zi and then specify the absolute price.
5. Take the price of the greater of the absolute difference in prices them.
In the study, coefficient used is 0.05, while visual learning style got 0.074 and parents attention gained 0.533, also students achievement
