This research focuses on the management of aquatic plants ponds in the schoolyard and the teaching design by the method of action research, in which teachers are researchers. By doing questionnaires and interviews in school, we explore the teacher's needs in aquatic plants and teaching assistance. In this research, we found that teachers' needs are highest on providing aquatic plant labels (79%), narrator training (75%) and to open a study session (67%). Under the combination of teaching and managing, students learn how to plan and maintain aquatic plants ponds in the schoolyard. They also practice maintaining environment by participating in the managing work. Thus their ability of solving problems can be established. The conclusion and suggestion provided by this study can be a reference in the management of aquatic plants ponds in the schoolyard and the teaching design for teachers.
