What Difficulties that Students Working in Mathematical Reasoning Questions?

摘要

Reasoning skill plays an important role in developing all other mathematical skills. However, the results of subhan's research (2017) inform that students are still weak and have difficulty in solving mathematical reasoning questions. Therefore, a study to analyze students' difficulties in solving reasoning questions should be conducted to overcome this problem. Participants in the study were 15 of the 25 public high school students in Bantul district of Yogyakarta who had completed mathematical reasoning questions. They were deliberately chosen because when they completed mathematical reasoning questions from 25 students only 15 students completed mathematical reasoning questions in their entirety. The instruments of mathematical reasoning are as many as five questions in the class XI line material that has been tested for quality. The analysis was performed using types of difficulties adapted from procedure Newman which includes (1) reading, (2) comprehension, (3) transformation, (4) process skill, and (5) encoding. The results of the study indicate to encoding difficulties of 37.93%, comprehension difficulties of 24.14%, transformation difficulties of 19.54%, and process skill difficulties of 18.39%.
