This study aimed to analyze the STEAM elements and types of convergence of pre-service teachers’ perspectives on the teacher’s guidebooks of national science textbooks and government’s authorized science textbooks of elementary school. As a result of analyzing the STEAM elements by classifying them into “unit introduction,” “science exploration,” and “creativity・convergence” periods, which are the science curriculum class system, the STEAM elements showed similar tendencies in all subject scopes. The units with the largest or smallest ratio of sum of “S + 2 and higher” of the STEAM convergence elements in the units of the “science exploration” classes and the “creativity·convergence” classes were the same, respectively. These results mean that teachers need to establish instructional strategies based on the viewpoint of STEAM activities in the stage of the “science exploration” periods corresponding to the unit. Moreover, for effective STEAM convergence education, it is necessary to make the supplement of the contents of the “science exploration” units in connection with the contents of the “creativity・convergence” unit in the description of teacher’s guidebooks.
