Abstract Implementasi Media Audiovisual berbasis PBL untuk Meningkatkan Kemampuan Berfikir Kritis Siswa: This implementation research is to find out the audiovisual media based on Problem Based Learning (PBL) in improving students' critical thinking skills. The method used was a quasi-experimental pretest-posttest control group design. The research population was all students of class XI MIPA, one of the senior high schools in Bandar Lampung. The sample was obtained by purposive sampling technique, namely class A as the experimental class (learning using PBL-based audiovisual media) and class B as the control class (learning using conventional media). The application of PBL-based audiovisual media is measured by the difference in the average value of n-Gain which is significant on students' critical thinking skills, both in the experimental class and the control class. The results of the calculation of the difference test obtained that the average n-Gain value of students' critical thinking abilities in the experimental class was greater than in the control class. The resulting effect size calculation can be interpreted as learning with PBL-based audiovisual media has an effect on increasing students' critical thinking skills on redox material, by 81%. The conclusion is that the application of PBL-based audiovisual media has an effect and is effective on increasing students' critical thinking skills.Keywords: PBL-based audiovisual media, critical thinking skills.DOI: 10.23960/jppk.v10.i3.2021.14

Abstract

In December 2019, there was an outbreak of a virus known as Covid-10. To prevent the spread of Covid-19 in Indonesia, the government made a Work From Home (WFH) policy. The existence of this WFH policy has an impact on the education sector, namely on the implementation of teaching and learning activities which were originally face-to-face to be changed online. Online learning on osmotic pressure material is still lacking in resources. The purpose of this research was to develop an e-book on the subject of osmotic pressure, describe the validity, teacher responses, and student responses. The research method used is Research and Development according to Borg and Gall until the fifth stage. The results of expert validation of e-books on aspects of the suitability of the content of the material, aspects of readability, and aspects of design attractiveness obtained high criteria. The results of the teacher's responses on the attractiveness aspect of the material content, the readability aspect, and the attractiveness aspect obtained very high criteria. The results of student responses on the readability aspect and the attractiveness aspect obtained very high criteria. Based on the results of the study, the e-books on the material of osmotic pressure generated from this study is valid.Keywords: Covid-19, Corona Virus Disease, Work From Home, E-book,Osmotic Pressure DOI: 10.23960/jppk.v10.i3.2021.05

Abstract

Education in Indonesia has changed from offline learning to online learning because of the corona virus. The corona virus has been endemic in Indonesia since early March 2020. The COVID-19 pandemic has changed various aspects of human life, including in the field of education. This condition causes all elements of education to utilize ICT for use in the learning process. One of the uses of ICT can be applied to the development of learning resources. The learning process during the pandemic requires learning resources that are interesting, fun, and in accordance with the applicable curriculum. This research is a type of development research that aims to describe the validity, teacher responses, and student responses to e-books on chemical equilibrium material for online learning during the covid-19 pandemic. The research method used is the Research and Development (RD) method. E-book developed using book creator application. Based on the results of expert validation of the developed e-book, an average percentage of 76.29% was obtained with high criteria in the aspect of content suitability. In the construction aspect of 82.95%, readability of 82.22%, and attractiveness of 83.8%, all three have very high criteria. The results of the teacher's response to the suitability aspect of the material content are 86.67%, readability is 85.6%, and attractiveness is 86.8%, all three have very high criteria. The results of students' responses to the readability aspect were 84.5% and attractiveness was 83.9%, both of which had very high criteria. From the research results it can be stated that the e-book developed is valid.Keywords: e-Book, chemical equilibrium, book creator, covid-19 pandemicDoi: 10.23960/jppk.v10.i3.2021.01
