PENERAPAN MODEL PEMBELAJARAN TWO STAY TWO STRAY DALAM MENULIS TEKS BIOGRAFI PADA SISWA KELAS X SMKN 1 JATIBARANG

This study was motivated by students’ difficulties in developing ideas and expressing them in biographical texts. Many students were less active and faced challenges in using appropriate structure and language. Therefore, the Two Stay Two Stray (TSTS) learning model was applied as an alternative solution. This study aims to describe teacher and student activities in learning to write biographical texts using the TSTS model and determine its effectiveness in improving the writing skills of tenth-grade students at SMKN 1 Jatibarang. The research employed a quasi-experimental method with a Nonequivalent Control Group design. The population consisted of 423 students, with class X TJKT 1 (35 students) as the experimental class and X TJKT 2 (35 students) as the control class, selected through purposive sampling. Data were collected through observation and written tests (pretest–posttest). The results showed increased learning activity, with teacher activity scores reaching 83.88 and student activity in the experimental class 83.33 (good category), while the control class scored 73.33 (fair category). The average writing score in the experimental class rose from 62.2 to 87.3, while the control class increased from 63.2 to 77.4. The Independent Samples t-test showed Sig. (2-tailed) 0.000 < 0.05 and t-count 13.019 > t-table 1.995, indicating a significant difference. Thus, the TSTS model effectively improves students’ writing ability, activeness, and collaboration.
