Pengembangan Perangkat Pembelajaran Model Problem Based Learning untuk Melatihkan Keterampilan Berpikir Kreatif Siswa SMA pada Materi Angiospermae.

Development of Problem Based Learning Model Learning Tools to Practice Creative Thinking Skills for High School Students on Angiosperms Material.

Salah satu keterampilan abad 21 adalah berpikir kreatif. Berpikir kreatif dapat dilatih kepada siswa melalui model problem based learning (PBL), untuk itu dibutuhkan perangkat pembelajaran berbasis model PBL pada materi Angiospermae. Tujuan penelitian ini menghasilkan perangkat pembelajaran model problem based learning untuk melatihkan keterampilan berpikir kreatif siswa SMA pada materi Angiospermae yang valid, praktis, dan efektif. Penelitian ini merupakan jenis penelitian pengembangan dengan model 4-D (define, design, develop, desseminate). Tempat penelitian dilaksanakan di Pascasarjana Unesa, sedangkan uji coba perangkat pembelajaran diimplementasikan pada siswa kelas X SMA Unggulan Harapan Ummat Mojokerto dengan 30 siswa di kelas replikasi 1 dan 29 siswa di kelas replikasi 2 pada semester genap 2020/2021. Data penelitian diperoleh melalui metode validasi dengan dua validator,  metode observasi dua pengamat untuk data kepraktisan, dan data keefektifan dengan instrumen tes. Analisis data dilakukan secara deskriptif kuantitatif. Hasil penelitian menunjukkan 1) validitas perangkat pembelajaran yang dikembangkan meliputi Rencana Pelaksanaan Pembelajaran (RPP), Lembar Kegiatan Siswa (LKS), dan Instrumen Penilaian yang dikembangkan berturut-turut memperoleh skor 3,66; 3,70, dan 3,73 dengan semuanya berkategori sangat valid; 2) kepraktisan perangkat pembelajaran yang dikembangkan ditinjau dari pengamatan keterlaksanaan RPP berkategori sangat baik dengan skor  3,50 dan hambatan yang terjadi ketika pembelajaran dapat teratasi; 3) keefektifan perangkat pembelajaran yang dikembangkan berdasarkan peningkatan keterampilan berpikir kreatif dengan rata-rata n gainscore pada replikasi 1 dan replikasi 2 berturut-turut memperoleh skor 0,61 (berkategori sedang) dan skor 0,60 (berkategori sedang). Soal berpikir kreatif yang dikembangkan pada semua indikator mempunyai sensitifitas sedang dengan respon siswa sangat positif (89,72%) terhadap kegiatan pembelajaran dan komponen pendukung pembelajaran. Berdasarkan hasil analisis data, dapat disimpulkan bahwa perangkat pembelajaran model problem based learning yang dikembangkan valid, praktis, dan efektif untuk melatihkan keterampilan berpikir kreatif siswa SMA pada materi Angiospermae.

One of the 21st century skills is creative thinking. It could be trained to students through problem based learning (PBL) models, from this case, PBL model-based learning tools are needed on Angiosperms material. The purpose of this study is to obtain model learning tools on problem based learning to train high school students' creative thinking skills on valid, practical, and effective Angiosperms material. The type of this research is development research by a 4-D model (define, design, develop, disseminate). The place of this research was carried out at UNESA postgraduate program, while the trial of learning tools was implemented in grade X at SMA Unggulan Harapan Ummat Mojokerto. This research needed 30 students at first replication class and 29 students at second replication class in the even semester 2020/2021. The research data was obtained through the validation method with two validators, the observation method with two observers for the practicality of the data, and the effectiveness of the data with a test instrument. Data analysis was carried out in a quantitative descriptive method. The results of the study show 1) the validity of the developed learning tools which include Learning Implementation Plans, Student Activity Sheets, and Assessment Instruments which were developed successively to obtain a score of 3.66; 3.70, and 3.73 with all of them categorized as very valid; .2) the practicality of the learning tools developed in terms of observing the implementation of the lesson plans are categorized very well by a score of 3.50 and the obstacles that occur when learning can be overcome; 3) the effectiveness of the learning tools developed based on increasing creative thinking skills by an average gain score of n at first replication and second replication, respectively obtained a score of 0.61 (medium category) and 0.60 score (medium category). Creative thinking questions which developed on all indicators have moderate sensitivity with very positive student responses (89.72%) on learning activities and learning support components. Based on the results of data analysis, it can be concluded that the problem-based learning model developed is valid, practical, and effective to train high school students' creative thinking skills on Angiosperms material. Based on the results of data analysis, it could be concluded that the problem-based learning model developed is valid, practical, and effective to train high school students creative thinking skills on Angiosperms material.
