Therefore, teachers and researchers need to emphasize students’ written self-evaluation to check and improve their solutions. However, some assumptions were inconsistent, neither their prior work nor other mathematical concepts. The similarity was the use of assumptions in solving the problem. They also applied multiple problem-solving strategies in working the problem. In implementing open-ended problems in the traditional context, students have different solutions based on their various experiences with the context, problem-solving schema, and mean-putting on the problem. No students evaluated their solution to the problem.
The results show that in solving the open-ended problem, 88.33% of students understood the problem, 59.72% were able to construct, and 72.22% applied the plan, while 52.78% wrote the conclusion. The instruments for this descriptive research were an open-ended problem and an interview sheet. Hence, this research aimed to analyze students’ abilities in solving an open-ended mathematical problem using the Songket context, particularly the Kembang Tengah motif.
One of many solutions is to apply a realistic context close to students. Many researchers stated that most students struggle to solve higher mathematical problems, including open-ended problems.
