Massive disruption in a short time has occurred due to the Global Pandemic of Covid-19. Digitization of learning has been inevitable at all levels of education after the pandemic forced us to close all educational institutions. This qualitative study aimed to describe perception and experience of teachers in secondary schools related to the digitization of education in aspects of learning implementation. Data were collected using an open-ended questionnaire which was completed online by 61 teachers in the fields of science and mathematics at the secondary schools. The data were analysed by conducting data reduction, verification and drawing conclusion. The results show that the teachers share their positive perception of the digitization of learning. Availability of devices and support system to digitized learning, such as curriculum, learning management system, internet connection, and electricity sources was the main obstacle to digitize learning so that it must be prepared immediately. Furthermore, knowledge about digital learning and strengthening of character education also needs to be prepared for educators and students in order to digitize math and science learning.
