Abstract
This research was conducted to describe the effectiveness of problem-solving student worksheet in improving communicating skills on acid-base topic. Population in this research was all student of 11th grade of science in public senior high school 13 Bandarlampung with class 11th Science 1 and 11th Science 4 as research samples with purposive sampling technique. This research used quasi experimental method with Non-Equivalent Pretest-Posttest Control Group Design. The effectiveness of this worksheet was indicated by the significant n-gain differences between the control class and the experimental. The results showed that the average score of n-gain communicating skills was 0.76 for experimental class and 0.59 for control class. Based on the t-test result, it found that the average score of n-gain experimental class was significantly different with control class. This problem-solving student worksheet is effective in improving student's communicating skills on acid-base topic. Penelitian ini bertujuan untuk mendeskripsikan efektivitas LKS problem solving dalam meningkatkan keterampilan mengko­mu­ni­kasikan pada materi asam basa. Populasi dalam penelitian ini adalah seluruh siswa kelas XI IPA SMA Negeri 13 Bandarlampung dengan kelas XI IPA 1 dan XI IPA 4 sebagai sampel penelitian menggunakan teknik purposive sampling. Penelitian ini menggunakan metode kuasi eksperimen dengan Non-Equivalent Pretest-Posttest Control Group Design. Efektivitas LKS ini ditunjukkan dengan adanya perbedaan n-gain yang signifikan antara kelas kontrol dengan eksperimen. Hasil penelitian me­nun­jukkan nilai rata-rata n-gain keterampilan mengkomunikasikan pada kelas eks­­­­perimen 0,76 dan pada kelas kontrol 0,59. Berdasarkan uji-t nilai rata-rata n-gain kelas eksperimen berbeda signifikan dengan kelas kontrol. Hal ini menunjukkan bahwa LKS problem solving efektif dalam mening­katkan keterampilan mengko­munika­si­­kan siswa pada materi asam basa.
