The online learning has become a critical policy direction in conducting the lectures, including in LPTK educating the Mathematics and Natural Sciences (MIPA) prospective teachers. For LPTK administering and organizing face to face meetings, the implementation can be through a Blended Learning system. As an LPTK that fully maintains face-to-face learning, what are the expectations of the MIPAs prospective teacher towards the blended learning support systems? This research was conducted by distributing questionnaires to the MIPAs students randomly. The opened-ended question questionnaires were developed based on the indicators of a support system for the blended learning. The results of the data analysis show that there are high expectations for the learning support system with some notes to improve Lesson Plans and interactions, Content, LMS (Learning Management Systems), assignment, Networks, Quota, and time management.
