The purpose of this study is to propose a systematic instructional design plan for information literacy instruction based on a concept-based curriculum. To this end, the key characteristics of the concept-based curriculum were analyzed, and the representative information literacy curriculum, ‘Library and Information Life’ Curriculum, was examined. The concept-based unit design in this study reorganized the 11 steps proposed by Erickson and Lanning into a six-step instructional design model consisting of: (1) defining the unit title and conceptual lens, (2) identifying unit strands, (3) developing generalizations and guiding questions, (4) identifying critical content and key skills, (5) designing assessment tasks and rubrics, and (6) organizing learning activities. In the stage of organizing learning activities, the concept-based inquiry model of Marschall and French was applied. This study is significant in that it discusses a conceptual learning approach within the field of information literacy instruction.
