PENGARUH MODEL PEMBELAJARAN STUDENT TEAMS ACHIEVEMENT DIVISION TERHADAP MATERI MENULIS TEKS BIOGRAFI KELAS X SMK

Abstract

ABSTRACT

This study was motivated by observations conducted in Grade X at SMK Negeri 3 Alasa, which revealed limited variation in teaching models and difficulties among students in developing their biographical text writing skills. The study aimed to determine the effect of the Student Teams Achievement Divisions (STAD) learning model on students’ ability to write biographical texts. A quantitative approach was employed using a quasi-experimental method with a nonequivalent control group design. The study involved 38 students divided into an experimental class and a control class, each consisting of 19 students. Data were collected through a pre-test and a post-test. The pre-test results showed a mean score of 51.26 for the control class and 56.89 for the experimental class. Following the treatment, the experimental class achieved a mean post-test score of 85.00, while the control class obtained 65.53. The hypothesis test yielded a significance value (2-tailed) of 0.001, which was lower than 0.05; therefore, H₀ was rejected and Hₐ was accepted. These findings indicate that the implementation of STAD had a significant effect on the biographical text writing skills of the students involved in the study. Thus, STAD may be considered an alternative learning model to support the development of biographical text writing skills among Grade X students at SMK Negeri 3 Alasa.

ABSTRAK

Penelitian ini dilatarbelakangi oleh hasil observasi di kelas X SMK Negeri 3 Alasa yang menunjukkan bahwa variasi model pembelajaran masih terbatas dan peserta didik menghadapi kendala dalam mengembangkan keterampilan menulis teks biografi. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Student Teams Achievement Divisions (STAD) terhadap kemampuan menulis teks biografi. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi-experimental dan desain nonequivalent control group design. Subjek penelitian berjumlah 38 peserta didik yang terbagi ke dalam kelas eksperimen dan kelas kontrol, masing-masing sebanyak 19 orang. Data dikumpulkan melalui tes awal (pre-test) dan tes akhir (post-test). Hasil pre-test menunjukkan rata-rata kelas kontrol sebesar 51,26, sedangkan kelas eksperimen sebesar 56,89. Setelah perlakuan diberikan, rata-rata post-test kelas eksperimen mencapai 85,00, sementara kelas kontrol memperoleh 65,53. Hasil uji hipotesis menunjukkan nilai signifikansi (2-tailed) sebesar 0,001, lebih kecil daripada 0,05, sehingga H₀ ditolak dan Hₐ diterima. Temuan ini menunjukkan adanya pengaruh yang signifikan dari penerapan STAD terhadap kemampuan menulis teks biografi pada peserta didik yang diteliti. Dengan demikian, STAD dapat dipertimbangkan sebagai alternatif model pembelajaran untuk mendukung pengembangan keterampilan menulis teks biografi di kelas X SMK Negeri 3 Alasa.
