VALIDITAS LKPD BERBASIS LITERASI SAINS UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS PADA MATERI BAKTERI KELAS X SMA

THE VALIDITY OF STUDENT WORKSHEETS BASED ON SCIENCE LITERACY TO TRAIN CRITICAL THINGKING SKILLS IN CLASS X BACTERI TOPIC

Pengembangan LKPD berbasis literasi sains dilakukan berdasarkan tuntutan kurikulum 2013 pada materi bakteri untuk melatihkan keterampilan berpikir kritis. Namun materi bakteri dianggap sulit dipahami oleh peserta didik karena banyak kata sulit, sehingga peserta didik cenderung menghafal dan mengingat. Hal ini menyebabkan keterampilan berpikir kritis peserta didik rendah. Penelitian ini bertujuan untuk menghasilkan LKPD berbasis literasi sains yang valid untuk melatihkan keterampilan berpikir kritis pada materi bakteri kelas X SMA. Jenis penelitian ini merupakan penelitian pengembangan dengan model pengembangan 4-D (define, design, develop, and desseminate), namun tahap disseminate tidak dilaksanakan. Data penelitian berupa hasil validasi dan teknik pengumpulan data menggunakan teknik validasi. Data dianalisis secara deskriptif kualitatif dengan metode validasi. LKPD ditelaah oleh dosen ahli pendidikan, dosen ahli materi, dan guru biologi dengan menggunakan instrumen lembar validasi. Hasil validitas LKPD berbasis literasi sains berdasarkan aspek syarat didaktik memperoleh skor 95,8% kategori sangat valid, syarat konstruksi 87,4% kategori sangat valid, syarat teknis 94,4% kategori sangat valid, karakteristik LKPD berbasis literasi sains 95,8% kategori sangat valid, dan keterampilan berpikir kritis 96,6% kategori sangat valid. Berdasarkan hasil yang diperoleh menunjukkan rata-rata skor validitas 94% dengan kategori sangat valid, sehingga LKPD berbasis literasi sains dapat dinyatakan layak untuk diimplementasikan dalam proses pembelajaran pada materi bakteri untuk melatihkan keterampilan berpikir kritis peserta didik. 

The development of student worksheets based on scientific literacy was carried out based on the demands of the 2013 curriculum on a bacterial topic to practice critical thinking skills. However, bacterial topic is considered difficult by students because many words are difficult so students tend to memorize and remember. This results in students' critical thinking skills being low. This study aims to produce a student worksheet based on scientific literacy valid to practice critical thinking skills in high school grade X bacterial topics. This type of research is a development study with a 4-D development model (define, design, develop, disseminate), but the stage is disseminated not implemented. Research data in the form of validation results and data collection techniques using validation techniques. Data were analyzed descriptively qualitatively with the validation method. Student worksheets were reviewed by educational expert lecturers, material expert lecturers, and biology teachers using instrument a validation sheet. The results of the validity of student worksheets based on scientific literacy based on aspects of didactic requirements obtained a score of 95.8% very valid category, construction requirements 87.4% very valid category, technical conditions 94.4% very valid category, characteristics of student worksheets based on scientific literacy 95.8% category very valid, and 96.6% critical thinking skills are very valid categories. Based on the results obtained shows an average validity score of 94% with a very valid category, so that the scientific literacy-based student worksheets can be declared feasible to be implemented in the learning process on a bacterial topic to train students' critical thinking skills.
