How to Scaffold Extroverted and Introverted Students in Mathematics?

---Every person has a different personality. It is important for teachers to consider these personality differences in providing scaffolding for their students. This study aims at: 1) describing the proper scaffolding with the students’ needs for each personality type; 2) formulating recommendations on how to give scaffolding to each student's personality type. It is a qualitative research on X grade students of SMK N Tengaran, Semarang in the year of 2019/2020. Research data is collected by observation, documentation, and interviews. The results show that 1) extrovert student appear to be more active in building interactions, while neurotic student prioritize comfort in providing scaffolding; 2) if the scaffolding is done by peers, each personality type requires scaffolding from peers with certain personality types; 3) there is no difference techniques used by students with different personality types in direct interaction, but for indirect interaction the choice of techniques is influenced by the level of ability. Based on these findings, the recommendation is the need to consider the characteristics of each personality type in: 1) involving students in the process of providing classical or personal scaffolding; 2) forming peer tutor groups; and 3) selecting the technique used in the scaffolding process.
