The purpose of this study is to redevelop and validate instructional analysis and consulting tools used for improving the quality of instruction. To do this, the existing instructional analysis tools were reviewed and analyzed, and in order to improve them, instructional analysis and consulting through three content validity reviews and consultations with on-campus instructors and off-campus instructional experts was conducted using the Delphi survey method. As a result of this study, an online and offline instructional self-diagnosis tool, an instructional questionnaire, a syllabus analysis tool, an instructional analysis (consulting) tool, and an instructional analysis rating table have been redeveloped. We expect that this will be helpful in preparing and utilizing instructional analysis and consulting tools suitable for the purpose, characteristics, and environment of instruction based on the process and the results of this study.
