The purpose of this study is to analyze the online class design and implementation status of universities by using the online class analysis tool to analyze the online education status. To this end, a cross-case analysis was conducted, and based on the analysis results, a practical design plan including design guidelines, considerations, and precautions for designing and executing more effective online classes was proposed. The result of this study is that, first, the ratio of middle and low level of online class design and execution suitability is more than twice that of upper level, so that there are various difficulties for instructors in the process of designing and executing face-to-face classes into online classes. And it was found. Second, the suitability of the class evaluation area in online class design and execution is the lowest, because the evaluation method and tool are not properly selected and implemented to consistently evaluate whether the goal of the class goal and content has been achieved. Third, in the learning environment area of online class design and execution, there is a lack of proper learning environment according to online class type due to the high ratio of middle and low level design by online class type, and it is not suitable for specific class types(lecture type, AOD type). It shows a biased design. Fourth, in the teaching method area, the ratio of the intermediate level of motivational and maintenance strategies was higher than that of other sub-areas, and it was necessary to plan and execute more detailed motivational strategies for learners with low self-regulation ability. Fifth, the ratio of middle and low level for explanation strategy and question strategy, which are common lesson strategies in online class types, was higher than the ratio for other sub-areas. It is necessary to properly plan and present a questioning strategy to students, and to enhance the effectiveness of interaction and communication with learners. It will be possible to reduce the difficulties that may arise when designing and executing online classes by providing instructors with information to be aware of when designing and using materials, evaluation methods, and tools.
