Subject of the research were students of class VIII-C at SMP Al-Azhar Palu, which consisted of 4 students (2 students in high self-efficacy and 2 students in low self-efficacy. Process of the research were: (a) formulated the thinking indicators based on SOLO taxonomy, (b) formulated a valid and reliable supporting instrument (super item test, self-efficacy scale, and interview manual), (c) took the subject of research based on self-efficacy condition, (d) took data to reveal the thinking level of students by super item test, (e) conducted a triangulation of data analysis, and (h) concluded the result of study. The result revealed that: (a) subject with high efficacy (HE) shows the tendency of thinking on the level of extended abstract, (b) subject with low efficacy (LE) shows the tendency of thinking on the level of relational, (c) subject with the high and low self-efficacy relatively shows a same tendency of thinking on the level of uni-structural, multi-structural, and relational as well as on the extended abstract
