Penelitian ini bertujuan untuk menghasilkan produk berupa perangkat pembel-ajaran aljabar menggunakan problem solving dalam problem posing berbasis pendekatan saintifik yang valid, praktis dan efektif ditinjau dari keyakinan terhadap pelajaran matematika (KTM) dan kemampuan berpikir kreatif (KBK) siswa SMA. Penelitian pengembangan ini menggunakan model Plomp. Hasil penelitian ini adalah perangkat pembelajaran aljabar menggunakan problem solving dalam problem posing berbasis pendekatan saintifik yang berorientasi pada keyakinan terhadap pelajaran matematika dan kemampuan berpikir kreatif siswa SMA berupa RPP dan LKS. Kualitas perangkat pembelajaran yang dikembangkan ditinjau dari aspek kevalidan, aspek kepraktisan dan aspek keefektifan. Hasil penelitian menunjukkan bahwa RPP dan LKS valid dan layak digunakan. Aspek kepraktisan berdasarkan penilaian guru terhadap RPP dan LKS adalah baik, dan skor kepraktisan berdasarkan hasil penilaian siswa adalah baik, dan persentase keterlaksanaan pembelajaran yaitu sangat baik untuk kelas XI IPA PI dan sangat baik untuk kelas XI IPA PA. Hasil angket KTM dan tes KBK juga mencapai kategori tinggi dan baik. Berdasarkan hasil tersebut, perangkat pembelajaran telah memenuhi kriteria kevalidan, kepraktisan, dan keefektifan. Developing algebra learning kits using problem solving approach in problem posing approach based on scientific approach AbstractThis study aimed to produce algebra learning kits using problem solving approach in problem posing approach based on scientific approach which was valid, practical, and effective viewed from belief in math and creative thinking skill of senior high school. This study was research and development which used Plomp’s model. The results of the research were algebra learning kits using problem solving approach in problem posing approach based on scientific approach oriented to belief in math and creative thinking skill for senior high school which consisted of lesson plans and students worksheets. The quality of learning kits developed to cover all aspects of validity, practicality, and effectiveness. The assessment result for validity of the lesson plans and students’ worksheets was valid and proper to use. The assessment result for practicality aspect based on teacher assessment about lesson plans and students’ worksheets was good. The assesment result for practicality aspect based on students assesment was good. Meanwhile, enforceability of learning with an average is very good) for class XI IPA PI and very good for class XI IPA PA. The result of belief in math questionaire and creative thinking test reach high and good category. Based on those results, the learning kits that has been developed was valid, practical, and effective.
Students’ creative thinking skill on scientific approach based on lesson study for learning community
