Kelayakan Teoritis Lembar Kegiatan Peserta Didik Berbasis Problem Based Learning untuk Melatihkan Keterampilan Berpikir Tingkat Tinggi pada Materi Sistem Peredaran Darah

Kelas XI SMA

The Theoretical Appropriateness of Problem-based Learning Students Worksheet on Circulatory System to Train Higher Order Thinking Skills of Grade Eleven Students

Peserta didik perlu dilatih keterampilan berpikir tingkat tinggi dengan harapan dapat menguasai keterampilan abad ke-21 supaya mampu mengimbangi perkembangan teknologi yang sangat pesat dan mampu bersaing dengan negara lain. Karena itu diperlukan bahan ajar untuk memfasilitasi peserta didik berlatih keterampilan berpikir tingkat tinggi. Penelitian ini memiliki tujuan utama yaitu menghasilkan bahan ajar LKPD berbasis Problem Based Learning pada materi Sistem Peredaran Darah kelas XI SMA yang layak secara teoritis berdasarkan hasil validasi para ahli. Penelitian ini menggunakan model penelitian 4D (four-D) meliputi tahapan define (pendefinisian), design (perencanaan), develop (pengembangan), tanpa tahap disseminate (penyebaran). Perangkat yang dikembangkan divalidasi oleh dosen biologi ahli materi, dosen biologi ahli pendidikan serta guru biologi SMA yang menggunakan  lembar. LKPD berbasis Problem Based Learning diharapkan dapat melatihkan keterampilan berpikir tingkat tinggi peserta didik. Hasil penelitian menunjukan bahwa LKPD layak secara teoritis mencapai 93,00% dengan kategori valid. Berdasarkan hasil penelitian LKPD yang dikembangkan layak untuk diuji coba. 

Students need to be trained in practicing higher of order thinking skills, and to be able to face challenges in the 21^st century as science and technology in 21^st century are rapidly developed. This learning medium facilitating students to train higher order thinking skills is needed to be developed. The purpose of this study was to produce Problem-based Learning Student Worksheets for practical higher order thinking skills of circulation system. This study used 4D development model which consists of Define, Design, Develop, without Disseminate. Worksheet created was validated by two biology lecturers; education and circulation system content experts, and a biology teacher of senior high school. Result showed that developed problem-based student worksheet was categorized as valid, scored 93.75% in appropriateness point. According the result, it can be concluded that problem-based learning worksheet for higher order thinking skills can be applied to be tested.
