specific populations or sample that comes
from two
identical populations that further were tested
for homogeneity by using levene test.
1. Validity and Reliability Test of Research Instruments
Data validity test aims to prove the validity of the data obtained from
the questionnaire. Data validity test is doing by using Product Moment
correlation Pearson Correlation. The data is considered to be valid if
it has a significant level of 0,05, and has coefficient correlation in
pearson correlation of 0,374. The result of validity test of the data in
this study can be seen as follows:

Based on the table 2 above, it shows that all testing assessment in
the school experiment for four meeting
showed that
all data
obtained is valid. The data meets the requirements of significance value of
0,05, therefore, all assessment items can be used and trusted to collect the
necessary data. The reliability test is done by
finding the number of reliability of assessment items by using the
standart formula of Item Alpha. After obtain the value α, then compare
that value to the reliable critical number on the table α, which is the
table that shows the relationship between the number of the questions
and the reliability of the instrument that can be seen in Table 3 below:
