Pengembangan E-Book Interaktif Berorientasi Contextual Teaching and Learning untuk Melatihkan Keterampilan Berpikir Kreatif pada Materi Pertumbuhan dan Perkembangan Tumbuhan

Development of Interactive E-Book Oriented Contextual Teaching And Learning to Train Creative Thinking Skills in Growth and Development Plants Topic

Bahan ajar berbasis elektronik dibutuhkan dalam pembelajaran jarak jauh secara kontekstual pada masa pandemi covid-19, yaitu dengan pendekatan Contextual Teaching and Learning (CTL). Tuntutan keterampilan juga harus dimiliki siswa pada abad ke-21, salah satunya melalui keterampilan berpikir kreatif yang dapat dicapai dengan pengembangan e-book interaktif materi pertumbuhan dan perkembangan tumbuhan. Penelitian ini memiliki tujuan menghasilkan e-book interaktif berorientasi CTL yang valid maupun praktis untuk melatih keterampilan berpikir kreatif. Model pengembangan pada penelitian ini menggunakan 4-D (Define, Design, Develop dan Diseminate), tanpa tahap Diseminate. Validitas e-book interaktif diperoleh dari validasi pakar yaitu 2 dosen ahli (pendidikan dan Biologi) dan 1 guru Biologi SMAN 1 Gondang Mojokerto. Kepraktisan e-book interaktif diperoleh dari uji keterbacaan menggunakan formulasi grafik Fry, angket respons guru yaitu tiga responden guru biologi berbeda sekolah dan angket respons 20 siswa heterogen kelas XII MIPA 4 SMAN 1 Gondang Mojokerto. Analisis data validitas dan kepraktisan yang digunakan adalah deskriptif kuantitatif. Hasil analisis e-book interaktif yang dihasilkan diperoleh persentase validitas sebesar 96,54% tergolong kriteria sangat valid. Kepraktisan e-book interaktif diperoleh dari hasil uji keterbacaan yang menunjukkan e-book interaktif sesuai digunakan siswa kelas XII SMA, serta respons guru dan siswa diperoleh persentase kepraktisan secara berurutan sebesar 97,22% dan 99,50% tergolong kriteria sangat valid. Berdasarkan penelitian tersebut, e-book interaktif berorientasi CTL ini dinyatakan valid dan praktis untuk diterapkan pada kegiatan pembelajaran karena mampu melatihkan keterampilan berpikir kreatif pada materi pertumbuhan dan perkembangan tumbuhan.

Electronic-based teaching materials are needed in contextual distance learning during the Covid-19 pandemic, namely  the Contextual Teaching and Learning (CTL) approach. Students must also have skills in the 21st century, one of which is creative thinking skills that can be achieved through the development of interactive e-books in plant growth and development materials. The purpose of this study is to develope a valid and practical CTL-oriented interactive e-book to train creative thinking skills. The development model in this study used 4-D (Define, Design, Develop and Disseminate), without a Disseminate stage. The validity of the interactive e-book was obtained from expert validation, namely 2 expert (education and Biology) and 1 Biology teacher at SMAN 1 Gondang Mojokerto. The practicality of the interactive e-book was obtained from the readability test using the Fry graphic formulation, the teacher's respons questionnaire, (namely three biology teacher respondents from different schools), and the respons questionnaire of 20 heterogeneous students of 12^th grade at SMAN 1 Gondang Mojokerto. The validity and practicality data analysis used was descriptively quantitative. The results of the interactive e-book analysis develope obtained a validity percentage of 96,54% with a very valid category. The practicality of the interactive e-book in terms of the readability test results showed that the interactive e-book was suitable for using by students of 12^th grade high shool, and the positive respons of teachers and students revealed percentage of 97,22% and 99,50% respectively with a very valid category. Based on the research, the developed CTL-oriented interactive e-books was declared valid and practical to be applied in learning activities because it was able to train creative thingking skills in plant growth and development materials.
