Students’ Cognitive Barrier in Problem Solving: Picture-based Problem-solving

Abstract

Pre-service teachers in primary education often have difficulty in solving mathematical problems, specifically fractions that are presented with a picture. In solving problems, some thought processes are needed by the teacher to reduce students' cognitive barriers. Therefore, this study aimed to reveal the cognitive barriers experienced by students in solving fraction problems. The cognitive barriers referred to in this study are ways of thinking about structures or mathematical objects that are appropriate in one situation and not appropriate in another situation. This study employed a descriptive-qualitative method. Furthermore, participants were followed up with in-depth semi-structured interviews to find out the cognitive barriers that occurred in solving fraction problems. This study discovers that the participants, in solving fraction problems, experienced all indicators of cognitive barrier and two cognitive obstacles are found as new findings that tend to involve mathematical calculations and violates the rules in dividing images into equal parts in the problem-solving procedure.

Deskripsi Kemampuan Pemecahan Masalah Matematis Ditinjau Dari Gender Pada Materi Bangun Ruang

“…Pemecahan masalah menjadikan siswa dapat memahami matematika (Albay, 2019). Pemecahan masalah dalam 904| pembelajaran matematika berfungsi untuk: a) sebagai langkah awal pengembangan ide dalam membangun pengetahuan baru dan keterampilan matematika (Yandari et al, 2019); b) memulai dan mempraktekan berbagai proses berpikir matematis (Nanna & Pratiwi, 2020); dan c) meningkatkan kreatifitas (Khalid et al, 2020).…”

Supporting students’ understanding of equivalent fractions using jelly

“…Konteks umum yang digunakan dalam mempelajari konsep awal pecahan yang dijelaskan oleh Streefland (1991) adalah pizza, irisan coklat, atau isian air menggunakan gelas ukur. Selain itu, beberapa penelitian di Indonesia telah mengembangkan konteks lain, seperti model persegi panjang (Putra, 2016), dengan bantuan tokoh (Nanna & Pratiwi, 2020), permainan tradisional Sidi Doka (Edo & Samo, 2017), konteks daun (Lisnani, 2019), manik susun (Pertiwi et al, 2017). Pembelajaran dalam penelitian ini menggunakan agar-agar sebagai konteks, yang lebih umum daripada pizza.…”

Analyzing the Gender Strategy in Math: Good, Routine, or Naive Problem Solver?

“…S2 subject already experienced obstacles when understanding the problem and could not be resolved, resulting in unsuccessful problem-solving. Obstacles in problem-solving could be because students are accustomed to generalizing every problem they find so that they carry out the same or similar strategies repeatedly (Antonijević, 2016;Nanna & Pratiwi, 2020). This can be seen in S2, she using the area square formula without paying attention to the problem again.…”
