Restrukturisasi berpikir siswa melalui pemunculan skema dalam menyelesaikan soal ujian nasional mata pelajaran Matematika

Restructuring student’s thinking can be called defragmentation of student’s thinking structures. Defragmentation of student’s thinking structures through scheme appearance to fix pseudo thinking student’sin solving problems HOTS test type for mathematics in the National Exam 2018. Pseudo Thinking happened because students did not reflect before answering, sostudents give the wrong answer. Pseudo thinking divided intofalse-pseudo thinking and true-pseudo-thinking. Hence, in this research to describe student’s structural thinking errors and the process of defragmentation of student’s thinking structures through scheme appearance to fixstudent’spseudo thinkingin solving problems ofHOTS test type for mathematics in the National Exam 2018.This research is qualitative research witha descriptive type.Researchers used three subjects to describe the defragmentationprocess of scheme appearance. The result of this research, all subjects experienced false-pseudo thinking and true-pseudo thinking.From the research,subjects can revealthat the process of scheme appearance that has been previously. So,subjects can solve problems.
