Pengembangan E-Modul Berbasis Problem Based Learning pada Materi Keanekaragaman Hayati untuk Melatih Berpikir Kritis Peserta Didik

Development of an E-Module Based on Problem Based Learning on Biodiversity Material to Train Student's Critical Thinking.

        Peserta didik memerlukan sebuah keterampilan untuk meningkatkan kualitas pendidikan di Indonesia. Penelitian ini bertujuan untuk mengembangkan E-Modul berbasis Problem Based Learning pada materi keanekaragaman hayati untuk melatih berpikir kritis peserta didik yang valid, praktis, dan efektif. Model penelitian ini menggunakan model 4D yang terdiri dari pendefinisian, perancangan, pengembangan, dan penyebaran. Metode pengumpulan data yang digunakan yaitu observasi, angket, dan tes. Instrumen yang digunakan yaitu lembar validasi, angket respons peserta didik, lembar pengamatan, dan lembar pretest dan postest. Subjek penelitian berjumlah 36 peserta didik kelas X-3. Data di analisis dua dosen biologi dan guru biologi kemudian dihitung berdasarkan skala likert 1-4. E-Modul yang dikembangkan sangat valid dengan hasil validitas yang ditinjau dari validitas isi dan konstruk memperoleh pesentase 89,5% dan 93,2%. Validitas konstruk mendapatkan persentase 91,6% dengan kategori valid atau sangat valid. Analisis kepraktisan E-Modul dianalisis berdasarkan hasil angket respons peserta didik dan hasil keterlaksanaan pembelajaran oleh observer yang kemudian dihitung menggunakan skala guttman 0-1 yang memperoleh persentase sebesar 97,2% dengan kategori sangat praktis dan didukung hasil pengamatan aktivitas peserta didik oleh tiga pengamat memperoleh persentase sebesar 94,2%. Analisis keefektifan E-Modul ditinjau dari hasil tes keterampilan berpikir kritis peserta didik dan hasil pengerjaan E-Modul kemudian dihitung menggunakan skor Gain dan mendapatkan skor sebesar 0,60 dengan kategori sedang. Berdasarkan hasil tersebut, dapat disimpulkan bahwa E-Modul berbasis PBL pada materi keanekaragaman hayati untuk melatih keterampilan berpikir kritis adalah sangat valid, sangat praktis, dan efektif dalam melatihkan keterampilan berpikir kritis peserta didik.

Participants are taught the skills needed to improve the quality of education in Indonesia. This research aims to develop an E-Module based on Problem Based Learning on biodiversity material to train students' critical thinking that is valid, practical and effective. This research model uses a 4D model which consists of definition, design, development and deployment. The data collection methods used were observation, questionnaires and tests. The instruments used were validation sheets, student response questionnaires, observation sheets, and pretest and posttest sheets. The research subjects were 36 students in class X-3. The data was analyzed by two biology lecturers and biology teachers and then calculated based on a 1-4 Likert scale. The E-Module developed is very valid with validity results in terms of content and construct validity obtaining percentages of 89.5% and 93.2%. Construct validity obtained a percentage of 91.6% with the category valid or very valid. The analysis of the practicality of the E-Module was analyzed based on the results of the student response questionnaire and the results of the implementation of learning by observers which were then calculated using a Guttman scale of 0-1 which obtained a percentage of 97.2% in the very practical category and was supported by practical results of observing participant activities by three observers. the percentage is 94.2%. Analysis of the effectiveness of the E-Module in terms of the results of students' critical thinking skills tests and the results of the E-Module work was then calculated using the Gain score and obtained a score of 0.60 in the medium category. Based on these results, it can be concluded that the PBL-based E-Module on biodiversity material to train critical thinking skills is very valid, very practical, and effective in training students' critical thinking skills.
