The purpose of this study is to develop UDL-based instructional design principles for enhancing digital literacy in university education. For this purpose, three research questions are as follows. (1) What is the UDL-based instructional design principles to enhance digital literacy in university education? (2) How is the validity of UDL-based instructional design principles for enhancing digital literacy in university education by expert feasibility test? (3) How is the usability of UDL-based instructional design principles for enhancing digital literacy in university education by three experts?. To develop the UDL-based instructional design principles for enhancing digital literacy, a literature review, Delphi method and expert feasibility test with five experts were conducted. Also, usability test was carried out by three experts. The expert feasibility test was conducted with the aim of asserting whether the the UDL-based instructional design principles are valid in theoretical and logical terms. Experts with doctoral degrees in education improved the details through three reviews. In the usability test, three instructors were asked to explore how effectively instructional design principles can be implemented to confirm their applicability to actual lessons. The results through these procedures are presented as follows. First, 8 instructional design principles and 16 detailed design guidelines were developed based on UDL to enhance digital literacy in university education. Each design principles were derived by referring to the characteristics of UDL based on the core competencies of digital literacy classified in this study. Also, the framework was modified so that each detailed design guidelines could represent the three core principles of UDL. Second, Delphi test and expert validation test were conducted on the draft design principles. In the first and second Delphi survey, through open-ended questions about the overall draft design principles, opinions such as modification and improvements of the principles were collected. Based on the main results, the framework was reorganized so that the characteristics of UDL could be revealed in the design principles. In the third Delphi test, the expert validation test was conducted. With the results, the UDL-based instructional design principles were generally valid. Finally, expert usability test was conducted by three instructional designer and instructor. The results of the expert usability test of UDL-based instructional design principles were somewhat low. However, it was evaluated that the class designed based on the UDL-based design principles was expected to have positive effects on the increase of digital literacy of college students. In addition, in order to improve the field utilization for the design principles in the future, it was confirmed that it was necessary to increase the understanding and utilization of the design principles users by developing a procedure model according to the lesson plan and steps. This study is meaning in that it aims to develop universal instructional design principles that can enhance digital literacy for learners with various ages, grades, majors, nationalities, and characteristics within the universities, and to validate internal and external validity through expert validation and usability evaluation. In addition, since the usability evaluation of the design principles was somehow low, various expirical follow-up studies such as field utilization of instructional design principles, learner response evaluation, and instructor response evaluation were strongly recommended.
