COMPARING STUDENTS’ ACHIEVEMENT IN LEARNING VOCABULARY THROUGH CLUSTERING TECHNIQUE AND DERIVATIONAL EXERCISES

Abstract

Penelitian ini bertujuan untuk mencari mana yang lebih baik antara Clustering Technique dan Derivational Exercises dalam meningkatkan pemerolehan kosa kata siswa. Penelitian ini melibatkan dua kelas eksperimental yaitu kelas XI IPS 1 dan XI IPS 2 di SMAN 1 Kalirejo. Data didapat melalui pemerolehan pre-test dan post test dan dianalisa menggunakan Independent Group T-test. Hasilnya menunjukan bahwa rata-rata nilai tengah dari post test di kelas pertama adalah 76,55 sedangkan di kelas kedua adalah 62,79 and level signifikannya (p) adalah 0,000. Hal ini berarti Clustering Technique secara signifikan lebih baik daripada Derivational Exercises dalam meningkatkan pemerolehan kosa kata siswa. Clustering Technique lebih sederhana untuk dimengerti oleh siswa daripada Derivational Exercises.

This research was intended to find out which one was better between Clustering Technique and Derivational Exercises in improving students’ vocabulary achievement. This research used two experimental classes, they are class XI IPS 1 and XI IPS 2 in SMAN 1 Kalirejo. The data were collected from the gain of pre-test and post test and analyzed by using Independent Group T-test. The result showed that the mean score of post test in the first class was 76.55 while in the second class was 62.79 and probability level (p) was 0.000. It means that Clustering Technique was significantly better than Derivational Exercises in improving students’ vocabulary achievement. Clustering Technique is simpler to be understood by the students than Derivational Exercises.

Keywords: clustering technique, derivational exercises, students’ vocabulary achievement.
