“THE

IMPLEMENTATION
OF
BRAINSTORMING ACTIVITIES IN IMPROVING STUDENTS’
VOCABULARY MASTERY (A CLASSROOM ACTION RESEARCH ON
THE EIGHTH GRADE STUDENTS OF SMP NEGERI 39 PURWOREJO
IN 2009/2010 ACADEMIC YEAR)” A thesis. Surakarta: Teacher Training and
Education Faculty of Sebelas Maret University, April 2013.
The aims of the research are: (1) to identify whether and to what extent the
implementation of brainstorming activities improves the students’ vocabulary
mastery and (2) to describe the class situation when brainstorming activities are
implemented in the classroom.
The method used in this research is collaborative classroom action
research; it is designed to improve students’ vocabulary mastery by using
brainstorming activities. The research was carried out on the eighth grade students
of SMP Negeri 39 Purworejo in the academic year of 2009/2010 in April until
May 2010. It is conducted in two cycles in which each cycle includes four stages
namely planning, action, observation and reflection. Each cycle consisted of three
meetings. The data is in the form of qualitative and quantitative data. The
qualitative data is collected through observation, interview, field note, research
diaries and photograph. The quantitative data is collected from the scores of pretest and post-test. The qualitative data was analyzed using Constant Comparative

Method and the quantitative data was analyzed by comparing the mean score of
pre-test and post-test.
The research findings showed that brainstorming activities can improve
students’ vocabulary mastery. The improvement of vocabulary mastery is
brainstorming activities could help students to learn four aspects of vocabularies
well. Their achievement could be seen from their performance in learning and
from the scores that improved gradually in every test. The mean score of the pretest is 6.11, the mean score of the post – test cycle 1 is 7.20 and the mean score of
the post – test cycle 2 is 7.80 The improvement of class situations can be seen
from the differences before and after the research. Before using brainstorming
activities, the teacher found difficulties in motivating and encouraging the
students to learn English. After implementing the uses of brainstorming activities,
the researcher could reduce the difficulties. The teaching learning process was
more effective because the students are more motivated in learning.
The researcher hopes that the finding of this research can enrich the
teacher’s technique in improving students’ vocabulary mastery and enrich the
knowledge and experience for other researchers and readers.

ABSTRAK
Ika Larastuti. K2205011. “PENERAPAN KEGIATAN CURAH IDE DALAM
MENINGKATKAN PENGUASAAN KOSAKATA BAHASA INGGRIS
SISWA (PENELITIAN TINDAKAN KELAS DI KELAS 8 SMP NEGERI 39
PURWOREJO TAHUN AJARAN 2009 – 2010” Skripsi. Surakarta: Fakultas
Keguruan dan Ilmu Pendidikan Universitas Sebelas Maret, April 2013.
Tujuan penelitian ini adalah: (1) untuk mengetahui apakah dan sejauh
mana penerapan kegiatan curah ide dalam meningkatkan penguasaan kosakata
siswa dalam pembelajaran Bahasa Inggris dan (2) untuk menjelaskan situasi kelas
pada saat kegiatan curah ide diterapkan di dalam kelas.
Metode yang digunakan dalam penelitian ini adalah penelitian tindakan
kelas kolaboratif; penelitian ini didesain untuk meningkatkan penguasaan
kosakata siswa menggunakan kegiatan curah ide. Penelitian ini dilakukan di kelas
8 SMP Negeri 39 Purworejo tahun ajaran 2009/2010 dari bulan April sampai Mei
2010. Penelitian dilaksanakan dalam dua putaran di mana setiap putaran terdapat

empat langkah yaitu perencanaan, pelaksanaan, pengamatan dan refleksi. Setiap
putaran terdiri atas tiga kali pertemuan. Data penelitian dalam bentuk kualitatif
dan kuantitatif. Data kualitatif diperoleh melalui pengamatan, wawancara, catatan
lapangan, catatan harian peneliti dan foto. Data kuantitatif diperoleh dari nilai pretes dan post-tes. Data kualitatif dianalisis menggunakan Metode Konstan
Komparatif dan data kuantitatif dianalisis dengan cara membandingkan nilai ratarata antara pre-tes dan post-tes.
Penemuan peneliti menunjukkan bahwa kegiatan curah ide dapat
meningkatkan penguasaan kosakata Bahasa Inggris siswa. Peningkatan
penguasaan kosakata siswa adalah kegiatan curah ide dapat membantu siswa
mempelajari empat aspek kosakata dengan baik. Peningkatan dapat dinilai dari
aktifitas belajar siswa dan nilai tes yang naik secara bertahap. Rata-rata pre-tes
adalah 6.11, rata-rata post-tes 1 adalah 7.20 dan rata-rata post-tes 2 adalah 7.80.
Peningkatan situasi kelas dapat dilihat dari perbedaan sebelum dan sesudah
penelitian. Sebelum penggunaan kegiatan curah ide, peneliti menemukan
kesulitan dalam memotivasi dan memberanikan murid untuk belajar bahasa
Inggris. Setelah penerapan kegiatan curah ide, peneliti dapat mengurangi kesulitan
dalam proses pembelajaran. Pembelajaran menjadi lebih efektif karena murid
lebih termotivasi.
Peneliti berharap penemuan penelitian ini dapat menambah teknik guru
dalam meningkatkan penguasaan kosakata siswa khususnya dalam pelajaran
Bahasa Inggris dan menambah pengetahuan dan pengalaman bagi peneliti lain dan

para pembaca.
