Abstract

Pembelajaran biologi akan bermakna bila siswa dituntun untuk mampu berpikir cermat, kreatif, dan logis, sehingga hasil belajar siswa dapat meningkat. Namun, hasil observasi dan identifikasi menunjukkan bahwa hasil belajar biologi siswa kelas VII SMPN 8 Huamual belum mencapai hasil yang diharapkan karena siswa pasif dan tidak termotivasi dalam pembelajaran. Oleh sebab itu penting untuk melakukan penelitian yang bertujuan meningkatkan hasil belajar biologi siswa SMP Negeri 8 Huamual melalui penggunaan model pembelajaran problem posing. Penelitian ini merupakan Penelitian Tindakan Kelas dengan analisis data secara deskriptif. Instrumen dalam penelitian ini yaitu, soal tes awal dan tes akhir (penilaian kognitif siswa), lembar observasi (penilaian afektif dan psikomotor siswa), serta lembar observasi peneliti yang dilakukan oleh guru (penilaian performa peneliti). Kesimpulan hasil belajar siswa dilakukan dengan membandingkan hasil penilaian dengan Kriteria Ketuntasan Minimal (KKM) yang telah ditetapkan sekolah. Penelitian berlangsung dalam dua siklus karena hasil tindakan pada siklus pertama menunjukkan bahwa nilai rata-rata siswa belum mencapai KKM. Namun, pada siklus kedua rata-rata nilai siswa telah melampaui KKM. Kesimpulannya yaitu, penggunaan model pembelajaran problem posing dapat meningkatkan hasil belajar biologi siswa SMP Negeri 8 Huamual.

Abstract

This study aims to analyze the characteristics of the items based on the classical test theory approach. This research is exploratory research with a quantitative approach. The data used in this study were data from the 2015 Science Subject National Examination for Junior High School in Daerah Istimewa Yogyakarta (DIY) province. The samples taken in this study were 9054 students. Test takers are grouped into high groups and low groups based on the total score obtained. Estimation of item parameters using Excel and QUEST. The results of the analysis show that based on the classical test theory approach, the average item difficulty level ) in the high group is in the easy category, while in the low group, it is in the medium category, the average item differential index ( ) shows that the test ability to distinguish students with high abilities and low abilities in both the high and low groups is in the unfavorable category; and the reliability coefficient of the test (ρ) in the high group has high reliability, and the low group has perfect reliability

Abstract

This study aims to develop a problem-based science learning module in biodiversity material for grade VII students of SMP Muhammadiyah Ambon. This research uses a 4-D development model from Thiagarajan, which consists of the stages of defining, designing, and developing. This study was conducted by involving 25 seventh grade students as a research sample at SMP Muhammadiyah Ambon. Data was collected through module validation, practicality questionnaires, and effectiveness questionnaires. The results showed that the modules developed were very valid, with a percentage of validation from material experts of 88%, media aspects of 85%, and language aspects of 80%. The practicality test shows that this module is very practical, reaching a percentage of 97%. Meanwhile, student responses to modules and learning activities showed a high level of effectiveness, with an average total response of 93.29%. Post-test results also showed a high level of effectiveness, with a percentage of 84%. Also indicated by a greater n-gain value equal to 0.8 in the high category. Based on the results of this study, it can be concluded that the problem-based science learning module on biodiversity material for grade VII students at SMP Muhammadiyah Ambon is suitable for use in the learning process.
