The current study researched the detailed reasons regarding the satisfaction and dissatisfaction of blended learners, as well as their needs. The survey results are as follows: First, Recipients of blended learning were satisfied because of “convenience in time use,” “higher efficiency than 3-hour classes,” and “utilization in reviewing.” Second, They were dissatisfied because of “lower understanding and concentration of cyber classes,” “lower efficiency,” “difficult attendance management,” “lack of response due to unilateral class structure,” “dullness of repeated learning,” and “difficulty of taking two styles of classes.” Third, The needs of the learners were “enhancement of cyber classes to be used for review and pre-studying,” “utilization of the classes for quizzes,” “use of cyber classes as supplementary classes using recesses between physical classes,” “utilization of various contents such as videos in cyber classes,” “improvements in attendance system,” “enhance speaking programs in the physical classroom and provide more grammar instructions in the cyber classrooms,” “provide chapters in the cyber lessons to allow learners to index classes better,” and “provide cyber classes with different learning contents than ones offered in the physical classroom.” Instructors should identify such needs of the learners to manage them better and produce adequate blended learning contents.
