The changing system in the current learning process at all levels of education due to the coronavirus pandemic. This study aimed to conduct literature review on project-based online learning during the Covid-19 pandemic and the impact on policies toward home learning activities. A project-based online learning system offers many ways to access learning materials for teachers and students. Many online learning platforms and media can be accessed for free. Some of the free platforms that have proven effective for managing online learning include Google Classroom and Edmodo. At least 12 free online learning resource applications can be used during the Covid-19 pandemic, including Rumah Belajar, ICANDO, Meja Kita, Indonesia X, Kelas Pintar, Google for Education, Microsoft Office 365, Quipper, Ruang Guru, Zenius, Sekolahmu, and Cisco Webex. Some obstacles in implementing online learning include limitations of the Internet and unfamiliar knowledge of teachers and students about the application of online learning media. Therefore, more effort is needed to address these issues, starting with individuals, families, educational institutions, providers, and government services.

This study aims to determine the effect of RME on the spatial abilities of Year 8 students concerning cuboids and cubes. Geometry problems often experienced by junior high school students, such as difficulty knowing the difference between cuboids and cubes, difficulties showing elements of cuboids and cubes, and difficulty imagining cuboids and cubes in the case of rotation. The teacher should not underestimate it because it will impact the next level of learning. Besides, spatial abilities are closely related to other mathematical concepts. One alternative is using RME. This research employed the quasi-experimental method, and samples were selected using purposive sampling techniques. The two classes were selected as samples in this study: the experimental and the control classes. Before conducting the main analysis test, the pre-test score students were tested with the t-test. The initial conclusion was that there was no difference in the spatial ability of the experimental class and the control class. The main analytic test in the post-test was done using U-test. The post-test results show that the average score of the experimental class is higher than the control class; RME positively influences students' spatial abilities.
