Abstract
According to NCTM, the five main mathematical process standards are problem-solving, reasoning and evidence, communication, linkage, and representation. In Indonesia, the mathematical problem-solving ability is still low. This is seen in the results of TIMSS and PISA. Regarding problem-solving skills, the topic of geometry is one of the areas measured in PISA. The topic of geometry is a mathematical subject that is considered difficult for students to complete. Therefore, the purpose of this study was to analyze the mathematical problem-solving ability and metacognition skills of students on the topic of geometry. The subjects of this study were six students of 8th grade in a private school in Cianjur, Indonesia. The category of low-ability students includes two students, the moderate abilities include two students, and the high abilities also include two students. This qualitative research was conducted by giving 4 problem-solving test questions to students. The results of this study showed that the high abilities students occupy looking back at Polya stages- they also have good metacognition skills which are in the regulation stage. The moderate abilities students occupy the stage of carrying out a plan- Also they are been in the monitoring stage of metacognition skills. The low-abilities students occupy the stage of devising a plan- also they are in the planning stage of metacognition skills. However, the problem-solving abilities of students depend on the level of difficulty of test questions. Because of every test questions different grade of adversity. We conclude that rate of the hardship of test question influence mathematical problem-solving ability and metacognition skills students. This research can be carried out further research on measuring students^ mathematical problem-solving abilities according to the level of difficulty of the questions that are systematically sorted on the test questions being tested.
