The development of electronic learning materials is very necessary in the midst of the COVID-19 pandemic which requires lecture activities to be carried out online. This was carried out to support physical distancing in an effort to break the chain of transmission of COVID-19. Currently, there are not many electronic learning materials available that lead to student centered learning (SCL) and can be implemented in the midst of the COVID-19 pandemic. The purpose of this research is to develop an eLEMA (Electronic Learning Material) application, an Android-based electronic learning material with content or material that can be accessed online and offline, and with features that make it easier for users to operate. This research is a research development (Research and Development; R & D) to develop Android-based ELEMA-SCL PROTOZOA (Electronic Learning Material-Student Centered Learning) for Zoology courses. This development model consists of 3 phases of approach, namely: (1) Phase 1: Needs Assessment; (2) Phase 2: Design; and (3) Phase 3: Develop / Implement. The product developed in the form of an Android-based eLEMA application made using the MIT App Inventor is feasible to implement. The implementation results show: (1) the effectiveness of online and offline lectures with a gain value of 0.52 in the Medium category; (2) student response to the implementation of eLEMA is positive. Thus the eLEMA application can be used for online and offline lectures during the COVID-19 pandemic.
Vertebrate and animal development subjects are covered in Zoology courses in the University of Palangka Raya which is learned in third and fourth semester. These subjects differ in content. Vertebrate course covers animal structure, while animal development course is more about the process of development. Today"s learning demands is to develop a critical thinking and build social interaction among students. Collaborative learning incorporating digital media through Lesson Study (LS) was implemented to improve learning outcomes in both subjects. Collaborative learning demands students to be self-minded, cooperative, and able to reveal thoughts mutually to their classmates to be employed for the above-mentioned purpose. The implementation of collaborative learning through LS was done with four cycles of "Plan, Do, and See" in Vertebrate and Animal Development subjects. These aimed to enhance student"s activities and critical thinking capabilities. The studied result showed improvement of activities in problem analysis stage, discussion and delivery of discussion results for zoology courses according to implementation of collaborative learning through LS cycles. Critical thinking capability of students was detected better in both subjects, mainly in the capability of conclusion drawing and presenting discussion results from assignments which were conducted by the aid of digital media. Collaborative learning incorporating digital media through LS could enhance activities and critical thinking capabilities of students.
The restrictions on social contact due to the Covid-19 pandemic also impacted the education sector causing many learning activities being carried out online. This research aims to 1) produce designs, 2) determine the feasibility level, and 3) determine the results of the development of problem-based learning digital teaching materials using Amphibia class subject materials in order to improve students’ communication skills. This research is development research using the ADDIE model with data collection techniques through interviews, validation, response questionnaires, observation of communication skills, and tests. Validation result data and response questionnaires were analyzed with the formula of eligibility criteria, respondent criteria and the N-Gain test.

Dalam pelaksanaan Kurikulum 2013, khususnya di Sekolah Dasar, penekanan dilakukan terhadap Penguatan Pendidikan Karakter (PPK), yang mana persentase pengajaran pendidikan karakter mencapai 80 persen, dan hanya 20 persen untuk pengetahuan. Berdasarkan surat edaran Menteri Pendidikan dan Kebudayaan Nomor 4 Tahun 2020 tentang penyelenggaraan pendidikan di masa pandemi Covid-19, pemerintah mengambil langkah antisipatif, yaitu menerapkan sistem pembelajaran secara daring untuk semua jenjang pendidikan. Guru dituntut untuk lebih kreatif dalam memberikan materi pembelajaran dan menanamkan nilai-nilai pendidikan karakter kepada siswa. Berdasarkan hasil pra-survei, terdapat dua permasalahan: (1) guru-guru mengalami kesulitan dalam mengintegrasikan nilai-nilai karakter utama, seperti religius, nasionalis, integritas, mandiri, dan gotong royong ke dalam RPP; (2) guru-guru sulit menentukan media pembelajaran yang tepat menjadi kelas online. Solusi yang diberikan oleh tim PKM adalah dengan memberikan pelatihan tentang cara mengintegrasikan nilai-nilai karakter ke dalam RPP dan cara membuat video pembelajaran untuk kelas daring. Narasumber dalam pelatihan ini adalah tim dosen dan mahasiswa FKIP Universitas Palangka Raya. Peserta pelatihan adalah seluruh guru di Sekolah Dasar Islam Terpadu (SDIT) Al Ghazali Palangka Raya. Hasil dari kegiatan ini menunjukkan bahwa guru telah berhasil merumuskan RRP yang memiliki nilai-nilai karakter yang terintegrasi dan mengimplementasikannya dalam proses pembelajaran. Selain itu, mereka juga telah berhasil merancang video pembelajaran dan mengimplementasikannya dalam pembelajaran daring.
