This study aims to describe the didactic design of Indonesian online learning based on a heutagogical approach. The research design used is a qualitative research design using the Design-Based Research (DBR) method. The research subjects were students, lecturers, and learning experts. The data collection methods used were observation and interview and data analysis techniques with four stages of analysis. The results showed that the didactic design consisted of the stages of preparation and implementation of learning. The learning preparation stage is carried out by providing scaffolding consisting of seven stages, namely (1) essential study analysis, (2) precondition, (3) orientation and discussion, (4) topic determination, (5) assessment discussion, (6) technical discussion, learning, and (7) reflection. Meanwhile, the stages of learning implementation consisted of four stages, namely (1) exploration, (2) connection and reflection, (3) material comprehension, and (4) final reflection of learning. The design provides support for the concepts of learning agents, efficacy and ability, metacognition and reflection, nonlinear learning, and learning how to learn.
