Validitas E-Book Terintegrasi Hands On Minds On (HOMO) Pada Materi Ekologi Untuk Melatih Keterampilan Berpikir Kritis Siswa Kelas X SMA

Validity Of Hands On Minds On (HOMO) Integrated E-Book In Ecology Topics To Train Critical Thinking Skill Of 10^th Grade Senior High School Students

Penelitian Pada masa Pembelajaran Jarak Jauh (PJJ) secara online dibutuhkan bahan ajar elektronik yang dapat memfasilitasi dalam pembelajaran biologi sekaligus melatihkan keterampilan berpikir kritis siswa. Salah satu tuntutan keterampilan yang harus dimiliki siswa pada abad ke-21 yaitu keterampilan berpikir kritis. Untuk melatihkan keterampilan berpikir kritis salah satunya dengan menggunakan pendekatan Hands On Minds On, hal ini karena karakteristik pendekatan tersebut mengarahkan siswa untuk berpikir dan melakukan percobaan sehingga dapat memunculkan keterampilan berpikir kritis yang dapat dicapai melalui pengembangan e-book terintegrasi Hands On Minds On (HOMO) materi ekologi dengan berbagai fitur seperti Bio-Think dan Bio-Lab. Tujuan penelitian ini yaitu menghasilkan e-book terintegrasi Hands On Minds On (HOMO) materi ekologi yang valid untuk melatihkan keterampilan berpikir kritis. Metode penelitian ini merupakan penelitian pengembangan dengan menggunakan model 4-D (Define, Design, Develop dan Diseminate), tanpa tahap Diseminate. Parameter yang diukur adalah validitas e-book dari aspek penyajian, kelayakan isi, kebahasaan, kesesuaian pendekatan hands on minds on, kelayakan aspek berpikir kritis, dan kegiatan hands on minds on. Validitas diperoleh dari hasil validasi oleh pakar yaitu dosen ahli biologi, dosen ahli pendidikan, dan salah satu guru biologi SMA Hang Tuah 1 Surabaya. Data yang diperoleh dianalisis menggunakan metode deskriptif kuantitatif. Hasil analisis menunjukkan bahwa  e-book yang dikembangkan mendapat persentase validitas sebesar 92,87% tergolong kriteria sangat valid. Berdasarkan hasil tersebut,  e-book terintegrasi Hands On Minds On (HOMO) pada materi ekologi untuk melatih keterampilan berpikir kritis siswa kelas X SMA yang dikembangkan telah dinyatakan valid berdasarkan validitas untuk diterapkan pada kegiatan pembelajaran.

            During the online Distance Learning (PJJ) period, electronic teaching materials are needed that can facilitate learning biology as well as train students critical thinking skills. One of the skills that students must have in the 21^st century is critical thinking skills. To practice critical thinking skills, one of them is by using Hands On Minds On approach, this is because the characteristics of this approach lead students to think and do experiments to that they can generate critical thinking skills that can be achieved through the development of an integrated e-book Hands On Minds On (HOMO) ecology topics with various features such as Bio-Think and Bio-Lab. The purpose of this research is to produce an integrated e-book HOMO valid ecologycal topics to practice critical thinking skills. This study uses the development of a 4-D without a disseminate stage. The parameters measured were the validity of the e-book from the aspect of presentation, the feasibility of the content, language, the suitability of the hands on minds on approach, the feasibility of critical thinking aspect, and hands on minds on activities. The validity was obtained from expert validation, namely a biologist lecture, an education expert lecture, and one of the biology teachers at Hang Tuah 1 High School Surabaya. The data obtained were analyzed using quantitative descriptive methods. The result of the analysis show that the e-book development has a validity percentage of 92,87% which is classified as a very valid category. Based on these results, the integrated e-book Hands On Minds On (HOMO) on ecology topics to train critical thinking skills of 10^th grade senior high school students developed has been declared valid based on its validity to be applied to learning activities.
