Penerapan ICT dalam pembelajaran sains, khususnya pembelajaran fisika, tidak dapat dihindari baik berbentuk media berbasis android atau berbasis online (web). Ilmu fisika berisi konsep-konsep yang bersifat konkrit dan banyak juga bersifat abstrak, sehingga siswa memerlukan pemikiran yang mendalam untuk memahaminya. Dengan bantuan modul e-learning siswa dengan mudah dapat menemukan konsep abstrak menjadi riil dan pengulangan penjelasan dapat dilakukan dimana saja atau tidak tergantung pada waktu dan tempat. Dalam makalah ini akan dijelaskan secara ringkas dan jelas metode atau teknik yang lazim digunakan untuk mengembangkan modul e-learning dalam pembelajaran fisika. Pembahasan bersifat kajian teoritis dari beberapa literatur yang terkait langsung dengan pengembangan modul e-learning dalam pembelajaran sains, khususnya pembelajaran fisika. Klasifikasi kajian pengembangan modul e-learning dalam makalah ini didasarkan pada model ADDIE. Hasil kajian teoritis menunjukkan bahwa pengembangan modul e-learning diawali dengan tahap Analisis (analisis kebutuhan akan modul), Desain (dalam bentuk self-learning), Development (sesuai masukan atau saran dari pakar), Implementasi (pada jenjang pendidikan yang sesuai), dan Evaluasi (kelayakan dan tanggapan dari pemakai). Berdasarkan hasil kajian teoritis dapat disarankan kepada semua staf pengajar fisika di perguruan tinggi untuk menyiapkan materi perkuliahan dalam bentuk e-learning. Berdasarkan semua tahapan pengembangan modul e-learning yang agak sukar dilakukan adalah pengembangan evaluasi berbasis web (e-learning). Implementation of ICT in science learning, especially physics learning, cannot be avoided from using of ICT either in the form of android based media or online based (web). Physics contains concrete concepts and many are also abstract, so students need deep thinking to understand them. With the help of e-learning module students can easily find the abstract concept into real and repetition of annotations can be done anywhere or not depending on the time and place. In this paper will be explained in a concise and clear method or technique commonly used to develop e-learning module in physics learning. The discussion is a theoretical study of several literatures that are directly related to the development of e-learning modules in science learning, especially physics learning. The classification of the study of e-learning module development in this paper is based on the ADDIE model. The result of the theoretical study shows that the development of e-learning module begins with the analysis phase (module requirement analysis), Design (in the form of self-learning), Development (according to expert input or suggestion), Implementation (at appropriate education level), and Evaluation (feasibility and responses from the user). Based on the results of theoretical studies can be recommended to all physics faculty in college to prepare lecture materials in the form of e-learning. Based on all stages of e

Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis siswa dan kegiatan belajar siswa pendidikan fisika dengan menerapkan model pembelajaran berbasis masalah (PBM) dengan metode blended learning. Metode blended learning diterapkan dengan mengintegrasikan pembelajaran tatap muka dengan pembelajaran online ke dalam sintaks pembelajaran PBM (langkah). Bentuk pembelajaran tatap muka dilakukan di dalam kelas, sedangkan bentuk pembelajaran online dilakukan dengan memanfaatkan fasilitas internet dan forum diskusi kelas online. Jenis penelitian adalah penelitian tindakan kelas (PTK) dengan metode penelitian deskriptif kuantitatif. Studi ini akan direncanakan dalam dua siklus. Setiap siklus terdiri dari empat tahap: perencanaan, melakukan, observasi, dan refleksi. Subjek penelitian ini adalah mahasiswa semester 1 fisika yang mengambil mata pelajaran biologi dasar dan dosen mata kuliah. Instrumen yang digunakan untuk mengumpulkan data adalah lembar tes berpikir kritis dan lembar observasi. Data hasil tes dilakukan dengan menghitung persentase berpikir kritis dan menentukan kriteria. Data kegiatan belajar yang diamati juga dihitung menggunakan rentang nilai yang muncul dan menentukan kriteria. Hasil penelitian menunjukkan bahwa persentase keterampilan berpikir kritis siswa pada siklus I adalah 52,12% (cukup kritis), sedangkan pada siklus II meningkat menjadi 63,27% (kritis). Kegiatan mengajar dosen pada siklus I dan siklus II adalah sama yaitu 36 (kategori baik). Aktivitas belajar siswa pada siklus I adalah 35 (kategori baik) dan pada siklus II yaitu 34 (kategori baik). Kesimpulan dari penelitian ini adalah penerapan pembelajaran berbasis pembelajaran (PBM) menggunakan metode blended learning dapat meningkatkan berpikir kritis dan aktivitas belajar siswa pendidikan jasmani dalam mata pelajaran biologi dasar. This study aims to improve students' critical thinking skills and learning activities of physics education students by applying problem-based learning model (PBM) with blended learning method. The blended learning method is applied by integrating face-to-face learning with online learning into the PBM learning syntax (step). Form of face-to-face learning is done in the classroom, while the form of online learning is done by utilizing internet facilities and online class discussion forums. The type of research is classroom action research (PTK) with quantitative descriptive research method. This study will be planned in two cycles.
