PENGARUH MODEL SOCIO-SCIENTIFIC ISSUE (SSI) BERBASIS LITERASI SAINS TERHADAP COMMUNICATION SKILL SISWA KELAS XI SMA

Abstrak

Communication skills are essential 21st-century competencies, yet many students still demonstrate limited ability to communicate scientific ideas because biology instruction has not fully encouraged discussion, argumentation, and evidence-based communication. Although the Socio-Scientific Issues (SSI) learning model has been widely investigated for improving scientific literacy, critical thinking, and argumentation, studies examining the effectiveness of science literacy-based SSI in enhancing senior high school students' communication skills remain limited. This study aimed to examine the effect of the science literacy-based SSI learning model on the communication skills of eleventh-grade students at SMA Negeri 15 Bone. A quantitative approach with a quasi-experimental design using a Nonequivalent Control Group Design was employed. The sample consisted of 66 students selected through purposive sampling. Data were collected using communication skills questionnaires, observation sheets, and documentation, and analyzed through descriptive and inferential statistics. Since the data were not normally distributed, the hypothesis was tested using the Mann–Whitney U test. The findings revealed that the science literacy-based SSI learning model had a significant positive effect on students' communication skills. These findings provide empirical evidence that integrating SSI with scientific literacy effectively promotes communication skills as a key competency for 21st-century learning. ABSTRAK Keterampilan komunikasi merupakan salah satu kompetensi abad ke-21 yang masih tergolong rendah karena pembelajaran biologi belum sepenuhnya mendorong siswa untuk berdiskusi, berargumentasi, dan mengomunikasikan gagasan secara ilmiah. Meskipun model Socio-Scientific Issue (SSI) telah banyak dikaji dalam meningkatkan literasi sains, berpikir kritis, dan argumentasi, penelitian yang secara khusus menguji efektivitas SSI berbasis literasi sains terhadap keterampilan komunikasi siswa SMA masih terbatas. Penelitian ini bertujuan untuk membuktikan pengaruh model pembelajaran Socio-Scientific Issue (SSI) berbasis literasi sains terhadap keterampilan komunikasi siswa kelas XI SMA Negeri 15 Bone. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi-experiment tipe Nonequivalent Control Group Design. Sampel berjumlah 66 siswa yang dipilih melalui purposive sampling. Instrumen penelitian meliputi angket keterampilan komunikasi, lembar observasi, dan dokumentasi. Data dianalisis menggunakan statistik deskriptif dan inferensial. Hasil uji normalitas menunjukkan bahwa data tidak berdistribusi normal, sehingga pengujian hipotesis dilakukan menggunakan uji Mann–Whitney U. Hasil penelitian menunjukkan bahwa model SSI berbasis literasi sains berpengaruh signifikan terhadap keterampilan komunikasi siswa. Temuan ini memberikan bukti empiris bahwa integrasi SSI dan literasi sains efektif mendukung pengembangan keterampilan komunikasi sebagai kompetensi penting abad ke-21.
