The aim of this research was to study teachers' learning management experience in teaching science after the COVID-19 pandemic. The sample consisted of 66 senior pre-service science teachers, who carried out fieldwork in the school, and 53 in-service science teachers; the selection was conducted by purposive sampling. The instrument of this research was a questionnaire consisting of five open-ended items. Data were collected through qualitative and then quantitative data analysis. The results revealed that pre-service and in-service science teachers chose the 5E instructional model for science learning management post COVID-19. Regarding the second research question, active learning was chosen by pre-service and in-service science teachers to suit the science learning approach. Science instructors in pre-service and in-service programs recommend that classrooms be fun-oriented. The limitations in terms of equipment, media, and technology were identified as a problem and an obstacle to science learning management. Science teachers desired to improve themselves in the issues of game and activity development, teaching technique, modern technology, and learning attraction.
