The writer calculated the data based on the procedure of the calculation. The formulation as follows:
a. Determining Mean of Variable X, with formula: =
= =
17 b. Determining Mean of Variable Y, with formula:
= =
= 10.5
c. Determining Standard of Deviation Score of Variable X, with formula: =
= =
=
9.01
d. Determining Standard of Deviation Score of Variable Y, with formula: =
= =
=
8.04
e. Determining Standard Error of Mean of Variable X, with formula: =
= =
= 2.06
f. Determining Standard Error of Mean of Variable Y, with formula: =
= =
= 1.84 g. Determining Standard Error of Difference of Mean of Variable X and
Variable Y, with formula: =
= =
= = 2.76
h. Determining with formula:
= =
= = 2.35
i. Determining in significance level 5 with Degrees of Freedom
df: df =
= 20 + 20 = 38
Because the value of degrees of freedom 38 is not mentioned in
, so the writer uses the closer value to 38 that is 40 as degrees of freedom. See appendix
The value of df 40 at the degrees of significance 5 or 5 of df 40 = 2,02.
j. The Testing of Hypotheses: The writer formulated the Null Hypothesis
and the Alternative Hypothesis Ha as follow:
Ho : There is no a significant difference achievement in learning reading comprehension between the students who are taught by
using Small Group Interaction and the students who are taught by using Whole-class Teaching.
Ha : There is a significant difference achievement in learning
reading comprehension between the students who are taught by using Small Group Interaction and the students who are taught
by using Whole-class Teaching. The assumption of this hypothesis as follows:
If ≥
, the Null Hypothesis is rejected. It means
there is a significant difference achievement in learning reading comprehension between the students who are taught by using Small
Group Interaction Technique and the students who are taught by using Whole-class Teaching.
If ≤
, the Null Hypothesis is accepted. It means
there is no a significant difference achievement in learning reading comprehension between the students who are taught by using Small
Group Interaction and the students who are taught by using Whole- class Teaching.
Based on the description of the calculation above, it can be inferred that:
1 The value of in the significance 5 is 2,02. see appendix
2 The value of 2.35
The writer summarized that ≥
, it means that the Null Hypothesis
is rejected and the Alternative Hypothesis Ha is accepted. The writer analyzed the result of calculation that
is rejected and Ha is accepted. It might have been due several factors
that are mentioned below: 1 The teacher who is conducting teaching through whole-class
Teaching offering translating activity between the students to the teacher while the teacher who is conducting teaching through
Small Group Interaction offering more varied activity including discussion, questioning and answering between students, and
sharing the difficulty of learning with other students. The varied activity in the classroom will make the students more interest to
learn. 2 The interaction during process of learning and teaching Whole-
class classroom are only from the teacher to the students while there are interactions between the teacher to the students, students
to other students, and the students to the teacher in Small Group Interaction. The interaction in Small Group Interaction classroom
will help students clarify in their own minds what they have already learned and understood.
3 The role of the teacher in whole-class teaching is a teacher centered. It means that the teacher is an authority in the classroom
and the role of students is that do what the teacher’s said while in Small Group Interaction classroom the teacher’s role is facilitator,
creator, etc. The students’ role in Small Group Interaction is not only do what the teacher’s said but also gate-keeper, checker, etc.
The roles in Small Group Interaction classroom will make the process of learning and teaching more relax.
4 The activity in Small Group Interaction classroom can be made students more active than the activity in whole-class teaching. So it
can be made students in Small Group Interaction classroom to improve their knowledge better than in Whole-class teaching
classroom.
