Emotional education has been used in elementary school curriculum which expects students not just have cognitive, skillful learning, but also have the generous, appreciative, respectful and caring attitude. Students promote their quality, perform loving nature and cherish life to reach the ideal of beautiful life and perfect morality. This research applied the theory of emotional teaching of STS teaching strategy and emotional and rational unification. It discussed emotional education in elementary school curriculum modules and found three methods. 1. Theme designed teaching: The teacher designed the whole teaching activity which was based on the understanding of students' natural-science-related experience and preconceptions and referred to the cognitive, skillful and emotional teaching targets of natural science teaching units in this semester. Students will build cognitive concepts from learning and learn skills from experiment and cultivate emotional capacity and disposition, attitude and motion from conversation and sharing. It can be explained with the example of the voice unit (grade 4, part 2). 2. Extended exploration: The teacher, based upon the recent curriculum, designed the teaching activity, which occasionally put into emotional activity. Sometimes we did extended exploration, or did the emotional combination from synthetic activity, which helped students cultivate their emotional capacity, disposition and emotional attitude that performed on the prospect of their actions. It can be explained with an example of lenses unit (grade 5, part 2). 3. Emotional learning sheets conduction: This teaching design is well-adapted for low level students. Because low level students have little life experience, it is difficult to proceed communication and dialogue with them. The teacher could base on the need of present natural science curriculum to design learning sheets as students' homework, which help parents and children discuss together. Parents guide children to further thinking by applying the questions of learning sheets, which promote the active prospect of children's actions. It can be explained with the example of blow bubbles unit (grade 1, part 1).
