. So, reading achievement of the students having high interest is better than the one of those having low interest.

0.05 4.00. Therefore, the null hypothesis H stating that there is no interaction
between teaching techniques interest in reading comprehension is
rejected. ing
comprehension depends on the student .
From the hypothesis testing above can be seen that there is interaction effect between the two variables, teaching technique and interest, so calculation
must be continued to Tukey test. It shows as follows:

7.32 From the computation above, it can be concluded that
7.32 is higher than 2.92.
Because between columns 7.32 is higher than
2.92, so the difference between columns is significant. It can be concluded that teaching reading
using clustering significantly differs from the one using Direct Instruction. The mean score of students taught using Clustering 25.923 is higher than
the one of those taught using Direct Instruction 20.962. It means that teaching reading using Clustering is more effective that the one using Direct
Instruction.

3.390 From the computation above, it can be concluded that
3.390 is higher than
2.92. Because
between rows 3.390 is higher than 2.92, so the difference
between rows is significant. It means that the students who have high interest are significantly deferent in reading competence from the students who have
low interest. The mean score of the students having high interest 26.542 is higher than those who have low interest 24.250. Thus, it can be concluded
that the students who have high interest have better reading comprehension than those having low interest.

7.750 From the computation above, it can be concluded that
7.750 is higher than
3.08. Because
7.750 between columns for students having high learning interest 7.750 is higher than
3.08, so the difference between columns for students having high learning interest is significantly different from the
one using Direct Instruction. The mean score of the students having high learning interest taught using Clustering 30.250 is higher than the one of
those taught using Direct Instruction 22.833. It means that teaching reading using Clustering to the students having high learning interest is more
effective than the one using Direct Instruction.
