So far, the practice of teaching in the classroom by students is often constrained by the readiness of students in preparing these teaching tools. To overcome these obstacles, it is necessary to design a didactic condition according to the obstacles experienced by students, to be able to guide students in carrying out teaching practices properly. This process requires planning (plan), implementation (do), and reflection (reflection) of learning so that the microteaching learning process is carried out based on lesson study. The purpose of this study was to develop a didactic design in microteaching learning for lesson study-based mathematics teacher candidates. The research method used is qualitative in the form of didactic design research. Based on the implementation of the didactic design of lesson study-based microteaching learning for prospective mathematics teacher students, it is concluded that this didactic design can be used as alternative learning to overcome the learning obstacles experienced by students in microteaching learning.
