Learning activities during the pandemic in Indonesia developed with two approaches, namely professional innovation and adaptive innovation. Both approaches to innovation are influenced by the perception of teachers when facing learning situations. A teacher's knowledge of learning applications is the basis for a person to make decisions about using a particular application in the class they manage. This study systematically reviews various empirical studies related to teachers' situation in Indonesia under specific conditions. A total of 50 research articles from the emerald and Wiley databases have been used to review specific criteria. This study was included in the theoretical framework, design and methodological application as in the research studied. This research's design is collected from various comprehensive case studies with different methods to confirm large quantities of samples with standardized instruments. This study's findings state that (1) teachers with many positive experiences about learning competencies can transmit to other teachers through professional development programs. (2) The preparation of teachers to face learning during the pandemic is a crucial professional ability to use. (3) Teachers may determine the application according to the managed class following the knowledge and objectives of the learning. (4) teachers can easily interpret and identify their academic potential.
