4 Answering, the teacher pointed one number, then the students from
each group who have the same number picked their hand and prepare answers for the entire class.
B. Relevant Researches
1. The research conducted by Hana Nur Azizah 2014 which is entitled: “Penerapan Model Pembelajaran Kooperatif Tipe Numbered Heads
Together NHT untuk Meningkatkan Aktivitas Belajar Akuntansi Siswa Kelas XI IPS 1 SMA Islam 1 Gamping Tahun Ajaran 20132014”. Based
on the research results, it can be concluded that there is an increase in Students Accounting Learning Activity of Grade XI IPS 1 at SMA Islam 1
Academic Year of 20132014 through the implementation of Cooperative Learning Model Type Numbered Heads Together NHT. It can be seen
from the scores of Students Accounting Learning Activity from the first cycle that has the score of 65,43, then increased to 74,14 in the second
cycle and increasing again to 88,85 in the third cycle. The similarity of this research with the research conducted by Hana
Nur Azizah is investigating the implementation of cooperative learning model type Numbered Heads Together NHT to enhance the accounting
learning activity. While the difference lies in the subject, time, and place of the research.
2. The research conducted by Fitri Sita Pambudi 2013 which is entitled: “Penerapan Model Pembelajaran Kooperatif dengan Tipe Numbered
Heads Together NHT Untuk Meningkatkan Prestasi Belajar Mata Diklat
Akuntansi Siswa Kelas X AK 1 SMK Batik 2 Surakarta Tahun Pelajaran 20122013”. The research result shows that after the implementation of
this learning model, students achievement showed an increase from the first cycle to the second cycle. This is evidenced by an increase in the
number of students who have the score of 70 to upwards of 64,70 or as many as 22 students in the first cycle, become 91,18 or 31 students in the
second cycle. The similarity of this research with the research conducted by Fitri
Sita Pambudi is investigating the implementation of cooperative learning model type Numbered Heads Together NHT. While the difference lies in
the research variables, namely learning achievement, subject, time, and place of the research.
3. The research conducted by Istiningrum 2012 which is entitled: “Implementasi Model Pembelajaran Kooperatif Tipe Numbered Heads
Together NHT untuk Meningkatkan Aktivitas Belajar Akuntansi Pada Siswa Kelas X Ak 2 SMK YPKK 2 Sleman Tahun Pelajaran 20112012”,
concluded that the average score of Student Activities of 24,60 prior to the implementation of cooperative learning model type Numbered Heads
Together was increased by 32,74 to be 57,34 in cycle 1. Furthermore, from cycle 1 to cycle 2 was also increased by 36,49 or obtained an
average score on the Student Activity in cycle 2 of 93.83. It also shows that the average score on the Student Activity in cycle 2 has reached the
successful action criteria. The score of successful action criteria is 80.
The similarity of this research with the research conducted by Istiningrum is investigating the implementation of cooperative learning
model type Numbered Heads Together NHT to improve the accounting learning activity. While the difference lies in the subject, time, and place
of the research.
