Among contemporary geography textbooks in senior high school, it applies to the development of environmental education related with soil geography quite a lot. However, instruction example in this field has been rare over past years; hence, I made an educational action study for designing and practicing an infusion curriculum of soil concepts and performed instructional activity, collected data for reflection among 5 classes, a total of 180 students in the ordinary classes of Grade 10 and 11. The finding indicated that a teacher's professionality would affect how these activities were designed, improve a student's will of learning, better realizing difficult concept. At last, such kind of curriculum applies to collaborative kind of instruction across fields to develop specialized field of optional courses.
