KETERAMPILAN KOMUNIKASI DENGAN PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBER HEAD TOGETHER PADA MATERI LARUTAN ASAM BASA UNTUK SISWA KELAS XI MIPA SMAN 1 KRIAN SIDOARJO

STUDENTS COMMUNICATION SKILLS WITH APPLICATION OF THE COOPERATIVE LEARNING TYPE MODEL NUMBER HEAD TOGETHER ON THE BASE ACID SOLUTION FOR CLASS  XI MIPA SMAN 1 KRIAN SIDOARJO

Penelitian ini bertujuan untuk mengetahui keterlaksanaan model pembelajaran kooperatif tipe Number Head Together, aktivitas siswa, keterampilan komunikasi siswa dan hasil belajar selama diterapkannya model pembelajaran kooperatif tipe Number Head Together pada materi larutan asam basa. Jenis penelitian yang digunakan adalah penelitian pre-eksperimen dengan menggunakan desain penelitian One Group Pretest Postest Design. Subjek pada penelitian ini adalah siswa dari dari kelas XI MIPA 7 SMAN 1 Krian, Sidoarjo yang berjumlah 32 siswa. Hasil penelitian ditunjukkan sebagai berikut: 1. nilai rata-rata keterlaksanaan siswa  dalam tiga pertemuan sebesar 3,67, 3,70, dan 3,51 dengan predikat sangat baik. 2. aktivitas siswa yang relevan dalam tiga pertemuan sebesar 95,31%, 95,62%, dan 92,62%. 3. kuantitas keterampilan bertanya siswa selama tiga kali pertemuan sebesar 53,12%, 71,88%, dan 31,25%, sedangkan kuantitas keterampilan berpendapat siswa selama tiga kali pertemuan sebesar 65,62%, 84,38%, dan 87,50 %. Kualitas bertanya siswa dengan predikat kurang baik dari pertemuan 1 hingga 3 berturut-turut sebesar 84,38%, 90,62%, dan 93,75%, sedangkan predikat cukup baik pada pertemuan 1 hingga 3 berturut-turut sebesar 0,00%, 3,12%, dan 0,00%, predikat cukup baik pada pertemuan 1 hingga 3 berturut-turut sebesar 15,62%, 6,25%, dan 3,12%, dan sedangkan predikat sangat baik pada pertemuan 1 hingga 3 berturut-turut sebesar 0,00%, 0,00%, dan 3,12%. Kualitas berpendapat siswa dengan predikat kurang baik dari pertemuan 1 hingga 3 berturut-turut sebesar 46,87%, 21,87%, dan 15,62%, sedangkan predikat cukup baik pada pertemuan 1 hingga 3 berturut-turut sebesar 6,25%, 6,25%, dan 3,12%, predikat cukup baik pada pertemuan 1 hingga 3 berturut-turut sebesar 43,75%, 62,50%, dan 53,12%. 4. Hasil belajar siswa secara klasikal mendapatkan persentase 78,12.

This study aims to determine the feasibility of the Number Head Together cooperative learning model, student activities, student communication skills and learning outcomes during the implementation of the Number Head Together cooperative learning model on the acid-base solution material. This type of research is pre-experimental research using the One Group Pretest Posttest Design research design. The subjects in this study were students from class XI MIPA 7 of SMAN 1 Krian, Sidoarjo, totaling 32 students. The results of the study are shown as follows: 1 the average value of student performance in three meetings of 3.67, 3.70, and 3.51 with a very good predicate. 2 relevant student activities in three meetings of 95.31%, 95.62%, and 92.62%. 3 the quantity of students' questioning skills during three meetings was 53.12%, 71.88%, and 31.25%, while the quantity of students' opinion skills during three meetings was 65.62%, 84.38%, and 87.50%. The quality of asking students with a predicate is not good from meetings 1 to 3 in a row at 84.38%, 90.62%, and 93.75%, while the predicate was quite good at meetings 1 to 3 in a row by 0.00%, 3.12%, and 0.00%, the predicate is quite good at meetings 1 to 3 in a row by 15.62%, 6.25%, and 3.12%, and whereas the predicate is very good at meetings 1 to 3 in a row by 0.00%, 0.00%, and 3.12%. The quality of opinion of students with a predicate is not good from meetings 1 to 3 in a row by 46.87%, 21.87%, and 15.62%, while the predicate was quite good at meetings 1 to 3 in a row at 6.25%, 6.25%, and 3.12%, the predicate is quite good at meetings 1 to 3 in a row at 43.75%, 62.50%, and 53.12%. 4 Student learning outcomes classically get a percentage of 78.12.
