30 For statement number ten, there was none of the students who strongly
disagreed and 2.38 or one student who disagreed. Therefore, there were 47.62 or twenty students who agreed and 50 or twenty one students who strongly
agreed. Therefore, the total score of agreement for the statement number ten was 97.62 or forty one students agreed. In this situation, the researcher was
successful to make the students be brave to speak English. According to Bailey 1994 as cited by Nunan 2003 asking the students to practice their fluency and
accuracy becomes the five principles in teaching speaking. Teaching how to be brave to speak in front of many people became an important thing for the students
because it helped them to have a good ability in one of English skills for themselves.
B. XII Graders’ Perception on the Use of Group Presentation Technique
to Improve Speaking Ability
In this section the researcher answered the research question number two. The second question of this research was about the XII graders’ perception on the
use of group presentation technique to improve their ability in speaking English. In order to make the researcher easier to answer the second question in research
question, the researcher divided the questions in the questionnaire into three parts: a XII graders’ ability to give opinion, b XII graders’ perception about group
presentation as the presenters, and c XII graders’ perception about group presentation as the audience.

31 were distributed to 42 students of grade XII IPA in SMA BOPKRI 2 Yogyakarta.
The findings of the research could be seen as follows:

Based on the first and second statements, the researcher presented the students’ experiences in speaking English during the implementation of group
32 presentation technique. From the table above it could be seen that none of the
students who strongly disagreed with the first statement. Next, there were 7.14 or three students who disagreed with the first statement in the questionnaire. Thus,
there were 83.33 or thirty five students who agreed and 9.52 or four students who strongly agreed with the first statement in the questionnaire. In conclusion,
the total percentage of the first statement in the questionnaire was 92.85 or thirty nine students who agreed. It could be concluded that almost all the students
had experience to speak English in the class. Huffman and Vernoy 2000 define perception as the process of selecting, organizing and interpreting sensory data
become useful mental representation of the world. By showing the finding of the first statement, it concluded that the students were able to select and organize the
sensory data and in the end they could interpret the data by giving their opinion. The statement number two was about the students’ ability to give their
opinion after the group presentation done. From the findings it concluded that none of them strongly disagreed in the questionnaire. Few of them disagreed with
the second statement and the score was 9.52 or four students. Next, there were 80.95 or thirty four of the students who agreed and 9.52 or four students who

their opinion after the group presentations done. Statements number three was about the students’ eagerness to give their
opinion during the group presentations. None of them strongly disagreed and 61.90 or twenty six of the students disagreed. Thus, 33.33 or fourteen of the

Next, for the statement number four was about argumentation’s skill awareness. There were none of the students who strongly disagreed and agreed.
Besides, there were 11.90 or five students who agreed and 88.09 or thirty seven students who strongly agreed with the statement number four. The total
percentage of the agreement was 100 or forty two students, it meant that all of the students agreed that people have different ability to give their opinion. It was
also supported by Altman, et al, 1985 that the way they receive the stimuli is one reason why people perceive thing differently, each person who receive the stimuli
will select specific cues and filters, or screens, out the others. Statement number five was about argumentation’s background awareness.
The result showed that there were none of the students who strongly disagreed and disagreed with the fifth statement in the questionnaire. Next, there were 30.95 or
thirteen students who agreed and 69.05 or twenty nine students who strongly agreed with the fifth statement in the questionnaire. Therefore, the total of
agreement was 100 or forty four students who agreed with the statement number five. It concluded that all of the students agreed that every people have their own
reason to give their opinion.

total score of agreement was 95.24 or forty students who agreed with the statement number eight. Finally, the result of the statements number six until eight
showed that almost all of the students agreed that the situation of a person affects people to give their opinion. It was also supported by Altman, et al 1985 that the
situation of the person also affects their perception. The next statement number nine presented about self-concept of the
students in giving their opinion. The statement number nine showed that none of the students who strongly disagreed and disagreed. Thus, 66.67 or twenty eight
