Defragmenting Struktur Berpikir Siswa SMP Dalam Menyelesaikan Masalah Bangun Datar

Abstract

This research purpose to description students’ error in solving problem of two dimension and effort defragmentation. Error analysis which execute base on concept construction error theory that include logical thinking error and hole contruction. This research done execute on students junior high school at eight grade of SMP in Pasuruan who finished two dimension material. Research subject is chose by students who are did mistake considerate of finishing comprehensiveness of students problem base Newman’s steps. From the result research was found that the students’ concept construction error in solving problem is erroring logic thinking and contruction hole. Defragmenting that id did by researcher is giving conflict cognitive to repar logic thinking error and appear scheme which still not build through scaffolding to hole that occur on students’ thinking structure.

Struktur Berpikir Siswa Terhadap Kesalahan Membaca Berdasarkan Teori Newman dalam Menyelesaikan Masalah Matematika Melalui Defragmentasi

“…Hal ini membuktikan bahwa siswa yang memiliki kesalahan membaca dalam menyelesaikan masalah matematika mampu melengkapi dan menata ulang struktur berpikir dengan memperbaiki kesalahan dan melengkapi tahapan berpikir dari tahap mengingat sampai tahap mengevaluasi dalam menyelesaikan masalah setelah pemberian defragmentasi dari peneliti. Hal ini sesuai dengan hasil penelitian yang dilakukan Supiarmo (2021) dan Bahrudin et al (2019) yang mendeskripsikan bahwa defragmentasi dapat memperbaiki kesalahan struktur berpikir dalam memecahkan masalah matematika.…”

Defragmenting Student’s Thinking Structures in Solving Mathematical Problems on PISA Model

“…In addition, based on the results of interviews with mathematics teachers at the school, they explained that errors were caused because students had difficulty understanding problems, making plans for completion, lack of knowledge of prerequisite material, and not being able to explain in detail the reasons related to the solutions found. Thus, this problem is the cause of problems with students' thinking schemes related to errors in solving problems (Bahrudin et al, 2019;Dorko, 2019;Tambunan, 2019). Therefore, appropriate treatment is needed to rearrange and improve the thinking structure related to the student's mistakes.…”

“…Several studies on defragmenting thinking structures have been carried out, including the research of Muhtadin (2020) which provides a defragmentation of students' thinking processes in solving story problems. Research by Bahrudin et al (2019), defragmenting students' thinking processes in solving the problem of flat shapes. Hidayanto's research (2017) shows that defragmenting students' thinking processes in solving mathematical problems, especially geometric problems, is essential.…”

Defragmentation Thinking Structure to Overcome Errors in Addressing Mathematical Problem

“…It is a process of restructuring students thinking into broader thinking structure so it can reach the deeper understanding and solve problems given (Subanji, 2016). Sakif in (Bahrudin et al, 2019) defined thinking structure defragmenting is a restructuring of students' thinking when having error in solving mathematical problems through the process of disequllibria, conflict cognitive, dan scaffolding so that students can fix their errors. Disequllibria is a condition where someone finds difficulty of confusion that reflects the unbalance between assimilation and accommodation (Subanji, 2015).…”
