This study involved a review of the current issues arising in relation to the use of lifestyle unit-based learning and reaffirmed the necessity of proceeding with this mode of teaching, which was founded on children’s independence and from the perspective of emphasizing career-oriented education. Based on this concept, a unit of study involving creating a drama, one of several event units that tends to develop formally due to its predictable nature, was examined and discussed. As a result of this examination, it was found that factors such as “development in which students’ ideas are reflected and whose content can be changed,” “development where students can be aware of the purpose of the unit and the target of the activity,” and “the teacher’s role as a supporter” are critical for the development of a learning unit founded on students’ agency and in which the students themselves take action.
