Abstract

The research was aimed to measure the effect of the three-step interview technique on speaking ability of the tenth graders of SMAN 2 Palangka Raya, and the significant difference between classes is taught using a three-step interview technique with those that are not of tenth graders of SMAN 2 Palangka Raya.

The research is included in quantitative research with Quasi-Experimental Design. The researcher designed the lesson plan, conducted the treatment, and counted the students’ scores by pre-test and post-test. The population of this research was 164 students of the tenth graders of SMAN 2 Palangka Raya. Based on the design of the study, the researcher only took two classes as a sample. There were X MIPA - 2 as experiment class and X MIPA - 3 as a control class. The number of the sample chosen was 50 students that consist of 27 students of the experiment class and 23 students of the control class. The sample was determined using cluster random sampling technique.

After getting the data from the pre-test and post-test, the researcher analyzed the data using SPSS 20 with a t-test formula to test the predetermined hypothesis. Based on the result of the analysis, it was found that the value of t-test = 2.76 with t-table = 2.01 at 5% level of significance and t-table = 2.68 at 1% level of significance with degrees of freedom = 48. It showed that the t-test was higher than the t-table. Besides that, the mean score on the pre-test of the experiment class was 52.81, and the control class was 61.78. While in the post-test, the mean score of the experiment class was increased into 68.04, and the control class was not increased but descend into 55.43. Based on the score, it can be seen that the mean score on the post-test of the experiment class was higher than the control class. The result of the testing hypothesis on the first research problem determined that the Alternative Hypothesis (Ha) was accepted, and the Null Hypothesis (Ho) was rejected. Then, in the second research problem, the Alternative Hypothesis (Ha) was accepted, and the Null Hypothesis (Ho) was rejected. It meant that teaching speaking by using a three-step interview technique affects students speaking ability. In other words, the three-step interview technique was effective in teaching speaking.

ABSTRAK

Penelitian ini bertujuan untuk mengukur pengaruh three-step interview technique terhadap kemampuan berbicara siswa kelas X SMAN 2 Palangka Raya dan perbedaan signifikan antara kelas yang diajarkan dengan menggunakan three-step interview technique dengan siswa yang tidak pada siswa kelas X SMAN 2 Palangka Raya.

Penelitian ini termasuk dalam penelitian kuantitatif dengan Desain Kuasi Eksperimental. Peneliti merancang rencana pelajaran, melakukan perawatan dan menghitung skor siswa dengan pra-uji dan pasca-uji. Populasi penelitian ini adalah 164 siswa kelas X SMAN 2 Palangka Raya. Berdasarkan desain penelitian, peneliti hanya mengambil dua kelas sebagai sampel, yaitu X MIPA - 2 sebagai kelas eksperimen dan X MIPA - 3 sebagai kelas kontrol. Jumlah sampel yang dipilih adalah 50 siswa yang terdiri dari 27 siswa kelas eksperimen dan 23 siswa kelas kontrol. Sampel ditentukan dengan menggunakan teknik cluster random sampling.

Setelah mendapatkan data dari pra-tes dan pasca-tes, peneliti menganalisis data menggunakan SPSS 20 dengan rumus uji-t untuk menguji hipotesis yang telah ditentukan. Berdasarkan hasil analisis, ditemukan bahwa nilai uji-t = 2,76 dengan t-tabel = 2,01 pada tingkat signifikansi 5% dan t-tabel = 2,68 pada tingkat signifikansi 1% dengan derajat kebebasan = 48. Ini menunjukkan bahwa uji-t lebih tinggi dari t-tabel. Selain itu, nilai rata-rata pada pra-tes kelas eksperimen adalah 52,81 dan kelas kontrol adalah 61,78. Sementara dalam pasca-tes, skor rata-rata kelas eksperimen meningkat menjadi 68,04 dan kelas kontrol tidak meningkat tetapi turun menjadi 55,43. Berdasarkan skor tersebut, dapat dilihat bahwa skor rata-rata pada pasca-tes kelas eksperimen lebih tinggi daripada kelas kontrol. Hasil pengujian hipotesis pada masalah penelitian pertama menentukan bahwa Hipotesis Alternatif (Ha) diterima dan Hipotesis Null (Ho) ditolak. Kemudian, pada masalah penelitian kedua Hipotesis Alternatif (Ha) diterima dan Hipotesis Null (Ho) ditolak. Ini berarti bahwa mengajar berbicara dengan menggunakan three-step interview technique memiliki efek terhadap kemampuan berbicara siswa. Dengan kata lain, three-step interview technique efektif dalam mengajar berbicara.
