Less than optimal learning during a pandemic risks disrupting the educational process, as well as efforts to protect and prosper students. The lack of optimal learning carried out during the pandemic is believed to have caused learning loss in students, both in cognitive and non-cognitive aspects. Learning loss in this context is defined as a decrease in students' knowledge or skills, because learning is not maximal at school or at home for a certain period of time. This knowledge is not only new knowledge, but also their old knowledge, which they have mastered but again forgotten due to the length of school closures during the pandemic.
This study aims to determine whether learning loss actually occurs or not and the purpose of this study is to map aspects of learning where learning loss occurs in schools during a pandemic. This study uses a qualitative descriptive study with the subject of the study, namely teachers and students at SMPN 1 Simpang Hilir and SMAN 1 Simpang Hilir. Teachers and students were selected as samples using purposive selection. This study involved 4 students and 4 teachers in one school, a total of two schools as many as 16 respondents. This study uses semi�structured interviews and interview guidelines as a data collection tool. Data
analysis used thematic analysis techniques used to analyze the results of the interviews.
This study discusses School Closures During the Pandemic; What's Missing and How Far is Learning in Schools Lost Due to School Closures? As explained in the discussion in chapter four, these two schools use online and offline learning practices but mostly use offline. Based on the research findings, apart from finding out whether learning loss is true or not, this research also aims to map
learning aspects where learning loss occurs in schools during the pandemic. The results of teacher and student interviews show that it is true that learning loss and
learning loss occur in all aspects, namely knowledge, skills and attitudes. The findings are in line with other research where this study illustrates learning practices during a pandemic both globally and in Indonesia. Based on these
studies, a number of problems were identified, both in cognitive and non�cognitive aspects.
