Penelitian ini bertujuan untuk mengetahui hubungan antara metode pembelajaran dengan keterampilan pengambilan keputusan dan hasil belajar kimia siswa kelas XI IPA di SMA/MA Negeri Mataram. Penelitian deskritif Expost Facto ini menggunakan subjek penelitian siswa kelas XI IPA di MAN 1 Mataram, SMAN 2 Mataram, dan SMAN 6 Mataram yang terbagi dalam 14 kelas dengan jumlah sampel sebanyak 236. Pengumpulan data keterampilan pengambilan keputusan siswa dengan angket dan observasi sebagai pendukung, sedangkan data hasil belajar kimia diperoleh dari dokumentasi guru mata pelajaran kimia. Uji coba instrumen dilakukan pada 30 responden. Uji validitas instrumen menggunakan korelasi Product Moment, dan uji reliabilitas menggunakan rumus Alpha Cronbach’s. Hasil uji hipotesis menggunakan uji anakova satu jalur diperoleh Fhitung > Ftabel (22,58 > 3,03) pada taraf signifikan 5% yang menunjukkan hipotesis alternatif (Ho) ditolak. Berdasarkan hasil tersebut, maka dapat disimpulkan bahwa ada hubungan antara metode pembelajaran dengan keterampilan pengambilan keputusan dan hasil belajar kimia siswa kelas XI IPA di SMA/MA Negeri Mataram Tahun Ajaran 2017/2018.

This study aims to evaluate an electronic student worksheets product based on discovery learning that valid and reliable on thermochemical topic. The development of electronic student worksheets-based on discovery learning follows the steps of the 4D development model, namely define, design, develop, disseminate. The feasibility test of the developed learning device was analyzed using a validation sheet. The assessment of the feasibility of the learning tools developed was carried out by three expert validators who are competent in the field of education at the University of Mataram. Criticisms and suggestions given by the validator are used as improvements to the developed electronic student worksheets. Data analysis was carried out using descriptive percentage techniques, Aiken's V index, and percentage of agreement. The validation results show that the developed electronic student worksheets component is included in the valid category with an average validity value of 0.79. The results of the agreement between validators showed that the developed electronic student worksheetshad a percentage of more than 75% which was included in the reliable category. Based on the results of the validation and reliability tests, the electronic student worksheets based on discovery learning developed can be concluded to be valid and reliable. A more complete and detailed explanation of the development of electronic student worksheets based on discovery learning and validation results is presented in this article.

The goal of this study is to create an E-worksheet product based on discovery learning that will help students improve their decision-making skills and scientific attitudes. This E-worksheet was created using the 4D development methodology, which includes the processes of define, design, develop, and disseminate. Students in class XI science SMAN 6 Mataram served as test subjects for this study. The limited trial is taught in one lesson, while the wide trial is taught in two classes. The ANCOVA test, descriptive percentage techniques, and percentage of agreement were used to analyze the data. The practicality data analysis revealed that teachers and students responded with a percentage of 80 and 86.42 percent, respectively, showing that the E-worksheet evolved in the practical category. The results of the effectiveness test using the ANCOVA test obtained Fcount > Ftable (8.28 > 3.98) on decision-making skills and Fcount > Ftable (6.94 > 3.98) on scientific attitude with a significant level of 5%. The null hypothesis (H0) is rejected, which means that E-worksheet influences discovery learning to improve students' decision-making skills and scientific attitudes in grade-eleventh science students. The E-worksheet based on discovery learning is practical and successful for enhancing students' decision-making skills and scientific attitudes toward grade-eleventh science students, according to the research objectives and findings.
