Problem solving skills are important to have in the 21st century. In the online learning period, students are required to be able to learn independently from home. However, in fact the motivation of students' learning has decreased. To facilitate students' self-learning during online learning, improving learning motivation and problem solving skills, teachers need to provide interesting learning materials. Therefore, this research aims to develop self-learning materials in the form of problem based learning e-module flipbooks on Environmentally Friendly Technology materials. This research is research and development with Lee Owens development model namely analysis, design, development and evaluation. The data collected in the form of qualitative data in the form of comments and suggestions validators and quantitative data in the form of validation scores of material experts, media and readability. The data collection instruments used are material expert validation test sheets, media experts, teachers and readability tests. Data analysis techniques are descriptive analysis. The results showed that the e-module flipbook developed has a succession of feasibility percentages from the validation tests of material experts, media experts and teachers, namely 84.03, 84.62 and 95.00%. Meanwhile, the percentage of readability tests to students was 87.81%. Teachers and students showed a response that the developed flipbook was interesting and suitable for self-learning during the pandemic. It can be concluded that, the e-module flipbook developed falls into the category of very valid (worth using) and excellent. It is expected to test the effectiveness of flipbooks to learning and develop flipbooks for other materials

This study and development aimed to produce a valid and feasible teaching material with the Creative Problem Solving (CPS) model on the activity of environmental pollution analysis using a mobile learning application in the COVID-19 pandemic era. The study model in this development was using the ADDIE method that limited to analyze, design, and develop stages where each stage passes the evaluation stage. The validity rate of the teaching material is obtained through a validity test by the validator while its eligibility rate is obtained through feasibility tests by the users. The validation result of materials in the teaching material had a percentage of 93.31 percent and the media feasibility test obtained a percentage of 95.60 percent. This teaching material was packed in a mobile learning form that consists of water, air, and land pollution materials. This teaching material displayed news articles, materials explanations, and presented in the form of animated videos, phenomena videos, pictures of environmental pollution, student worksheets, and mission-based learning activities. Animated videos have three animation characters that move and talk with different voices in each sub-chapter. The validation result by validators stated that the teaching material is valid and feasible, with a percentage of greater than or equal to 81 percent.

Penelitian ini memiliki tujuan untuk mengetahui keefektifan model pembelajaran inkuiri terbimbing dalam meningkatkan keterampilan berpikir kritis pada mahasiswa. Dengan menggunakan jenis penelitian studi literasi, pengumpulan artikel yang dilakukan dengan bantuan mesin pencari Harzing’s Publish Or Perish dengan kriteria yang digunakan yaitu artikel diterbitkan pada tahuan 2010-2020 namun diutamakan pada artikel yang diterbitkan pada 2015-2020. Hasil studi literasi yang telah dilakukan diperoleh bahwa keterampilan berpikir kritis yang dimiliki mahasiswa masih rendah sehingga diperlukan pengembangan keterampilan berpikir kritis. Padahal keterampilan berpikir kritis seharusnya dimiliki oleh masing-masing mahasiwa karena menjadi salah satu standart kelulusan perguruan tinggi. Salah satu cara untuk meningkatkan keterampilan berpikir kritis yaitu dengan pemilihan model pembelajaran yang tepat. Model pembelajaran inkuiri terbimbing menjadi salah satu model pembelajaran yang efektif dalam meningkatkan keterampilan berpikir kritis termasuk dalam meningkat keterampilan berpikir kritis pada mahasiswa. Hal ini dikarenakan sesuai dengan metode pengembangan keterampilan berpikir kritis mahasiswa yaitu dengan merumuskan pertanyaan atau permasalahan.

Online learning that has been carried out more or less in the past year has caused student studying saturation. The provision of material through Youtube videos, articles or handouts in pdf form is generally done by teachers. In fact, technology has provided many alternatives that can be used as more interesting learning media, for example Powtoon. Therefore, this study aims to provide training to teachers in developing materials in the form of Powtoon in order to increase students' learning motivation, especially during online learning. This research includes community service research. The steps taken are; 1) Pre-implementation, in the form of needs analysis, 2) Implementation, in the form of training with Powtoon development materials as learning media, filling out questionnaires, independent work, discussions and 3) Post-implementation, in the form of evaluation of activities. The implementation of the training showed the enthusiasm of the participants as seen from the life of the discussion session. Based on the questionnaire filled out by the participants, the implementation of the training has been well implemented with suggestions for adding other innovative media materials, and improving teacher competence in other matters. In addition, the results of the development and use of Powtoon media carried out by participants showed that students were enthusiastic and motivated in learning
