Students’ problem in communicating mathematical problem solving of Geometry

Mathematical Communication Process of Junior High School Students in Solving Problems based on APOS Theory

“…Departemen Pendidikan Nasional (2003) states that one emphasized aspect in mathematical learning is communication. There are several researchers have similar arguments to importance of mathematical communication in learning mathematics (Jung & Reifel, 2011;Kaya & Aidyn, 2014;Kosko & Wikins, 2010;Lamibao, Charita, & Namoko, 2016;Rohid, Suryaman, & Rusmawati, 2019;Smieskova, 2017;Sumaji, Sa'dijah, Susiswo, & Sisworo, 2019;Viseu & Olivera, 2012). Mathematical communication facilitates to improve conceptual understanding so it could help in solving problem (Smieskova, 2017).…”

“…It is in line with Kosko & Wikins, (2010) explaining that mathematical packaged in the form of group discussion could encourage students in improving conceptual understanding. To support the notion, Sumaji, Sa'dijah, Susiswo, & Sisworo, (2019) and Viseu & Olivera, (2012) states that communication could facilitate students understanding the process and taking decision in solving problem.…”

“…Those studies cover: First, open ended problem implementation in developing mathematics communication (Kongthip, Inprasitha, Pattanajak, & Inprasitha, 2012;Rodriguez & Bonner, 2018;Sumaji, Sa'dijah, Susiswo, & Sisworo, 2020;Thinwiangthong, S, Inprasitha, M, & Loipha, S, 2012). The findings were: (1) Rodriguez & Bonner (2018) state the use of open ended problem could improve teacher's skill in asking questions and creating dialogue between teacher and student more productive and better, (2) Thinwiangthong, Inprasitha, & Loipha (2012) revealed that mathematics class adopting lesson and transparent approach, could improve mathematical communication, (3) Kongthip et al, (2012) explained that schools in lesson study context and transparent approach allowed the students to have greater learning opportunity based on their potencies, thinking skills, actions, and expressions, and (4) Sumaji et al, (2020) found that (1) mathematical communication of students for both in written and spoken was on first level. It was in solving limited open ended problem on several concepts and (2) mathematical communication of students for both written and spoken was on level two.…”

Analysis of Students Errors in Mathematical Reasoning on Geometry by Gender

“…Students cannot change statements in problems to drawings or symbols. Students have problems communicating given problems and students have problems communicating mathematical problems in the form of written text [17].…”

The Effect Of Collaborative Problem Solving Strategies And Cognitive Style On Students' Problem Solving Abilities

“…According to Gok & Silay (2010), students often encounter difficulties when solving mathematical concepts related to real-world experiences and daily life. They make certain mistakes when trying to understand these problems, communicate, and test the concept (Saleh, Yuwono, Rahman, & Sa'dijah 2016;Sumaji, Sa'dijah, Susiswo, & Sisworo, 2019). Ineffective implementation of instructional strategies leads to poor problem-solving abilities (Mabilangan, Auxencia, & Belecina, 2011).…”
