Abstract
One of the mathematical abilities that focus on the ability to think about something that has been thought of is metacognitive ability. Metacognitive ability consists of knowledge, skills, and concepts. The purpose of this study was to describe the metacognitive skills of students and to know the type of difficulties in solving the problem of linear equations. The type of linear equation used in this study is a system of linear equations with three variables. The participants of this study were three students of grade 10 of senior high school. This research was a qualitative case study. The instruments used were the test, questionnaires, and interview. The result obtained was participants of the high group tended to easily understand the problem, easily to remember similar problem, know what step used to solve the problem, measure the time needed to solve the problem, but not yet able to evaluate the answer correctly. The participant of the middle group was not likely to be difficult in understanding the problem, easy to remember similar problems, able to measure the time needed to solve the problem, but had not been able to determine the initial step and evaluate the answers correctly. While the subject of the low group tended to be incapable of understanding the problem, considering similar problems, knowing the initial steps used to do the problem, measuring the time needed to solve the problem, and not being able to evaluate the answers correctly. When solving linear equations problems, participants had different difficulties. The type of difficulties possessed by participants who had good metacognitive skills tended to be from memory factors, whereas participants who had not good metacognitive skills tended to derive from initial idea factors, correct step determination, and memory of concepts. Thus, the researcher suggests the need to conduct further research with more participants.
