ABSTRACT
Metacognition is needed in solving mathematics problem. It is defined as the knowledge, awareness, and control of one’s thinking process. In solving mathematics problem, not all students are able to use their metacognitive that are able to process the thinking. The objective of this research was to describee Mathematics Students characteristics and level of metacognition in mathematical problem solving and to know students’ scaffolding question metacognitive in answer the question of problem solving at second semester State University of Medan. This research use qualitative data which is described to get the students’ metacognitive representation in mathematical problems. That is why this research is included in descriptive qualitative research.
Held in second semesters students’ of Mathematics regular class C 2015 State University of Medan. The subject in this research is the whole mathematics students’ who’s taking Calculus II at State University of Medan. The students’ given test then grouped into three groups that us high level ability, medium and low ability. Every group is taken two subjects to have interview to get more credible data. Then, the data is analyzed to get conclusion from each group. The result of the research is obtained that the high level ability students has reflective cognitive use. Medium level ability students have strategic metacognitive use. Low level ability students have aware use and tacit use.
Scaffolding questions given in the test should be help students in completing the problem. From the result of this research is hoped will be source of information and input material for mathematics lecturer, researchers, and all side which needed especially in Faculty of Mathematics and Natural Science State University of Medan’s environment.

CHAPTER 1 INTRODUCTION
1.1 Background
Mathematics is a universal science which very important in the aspects of technological progress and multidisciplinary. In Indonesia mathematics is regarded as one of disciplines which very important and has the most influence on the other multidisciplinary. The mathematics used as a compulsory subject and has been given early in the world of education in Indonesia. This is confirmed by Undang-Undang RI No. 20 Th. 2003 Tentang Sisdiknas (Sistem Pendidikan Nasional) Pasal 37 stated: “Mata pelajaran Matematika merupakan salah satu mata pelajaran wajib bagi siswa pada jenjang pendidikan dasar dan menengah.”
From the explanation above it is said that learning and knowing about the mathematics is very important. Mathematics it’s not only related with other multidisciplinary but also the development of modern technology and the power of human thought. So that it’s very needed in dimensions of knowledge and skills which is supporting in learning mathematics deeply. One of dimension aspect of knowledge and skills that interesting to be studied more deeply, especially in learning mathematics is metacognition.

From Brown (Hacker, 2009 : 7) that view the concept of metacognition as having four historical roots, each of which has provided foundation for approaches to strategies instruction, which we will take up in the next section. The first root is the issue of verbal reports as data—how reliable are people’s reports of their thinking processes? What we can express about what we know, or how does what we can express relate to what we know? The second root is the notion of executive control, which is derived from information processing models. These models feature a central processor that can control its own operations, which include planning, evaluating, monitoring, and revising. The third root is self-regulation, processes by which active learners direct and continuously fine-tune their actions. The fourth root that Brown et al. see underlying metacognition is what they call other regulation, or the transfer of control from other to self. This kind of regulation is based on Vygotsky’s theory that all psychological processes begin as social and then transformed through supportive experience to the intrapersonal, number of metacognition components that Brown et al. discuss within the four roots have relevance for reading. Actions such as self-regulating, planning, evaluating, and monitoring align well with what researchers have come to see as the processes in which readers need to engage in order to achieve successful comprehension. As Baker and Brown (Hacker, 2009 : 7) put it: “Since effective readers must have some awareness and control of the cognitive activities they engage in as they read, most characterizations of reading include skills and activities that involve metacognition”.

strategies/tactics/principles appropriate for solving the problem and why?”; and in some studies, (d) reflecting on the processes and the solution (e.g., “What did I do wrong here?”; “Does the solution make sense?”).
From the two expert it can be seen the importances of metacognitive and it’s component. There are relation of thinking process and question in our mind to contruct the answer of problem. And other expert Keiichi (Mulbar, 2008 : 3) in his research on Metacognition in Mathematics Education produced some findings, namely:
a). Metacognition plays an important role in resolving the conflict; b). Students are more skilled at solving problems if they have knowledge
of metacognition; c). In the framework of solving problems, teachers often emphasize specific strategies to solve problems and lack of attention to important features activities solve other problems; d). The teacher expresses some achievement more impressive at the intermediate level in the elementary school where these things important in mathematical reasoning and problem posing strategies.
From the observations of researchers when conducted PFE (Practice Field Experience), researchers observed that the students’ metacognition ability is still low. It is characterized by the existencies of students’ who can not and difficult to explain the results of their work in front of the class and still confused with the question given by his friends. Another problem was found in research there are still many students who pay attention well, but when the test the students can not get maximum results. So the researchers concluded that the ability of learner metacognitive need to be further investigated. From some of the reviews mentioned the importance of metacognition in mathematics and problems in mathematics, it’s necessary important to know the extent of stdents’ metacognitive in solving mathematical problems.

because Calculus is a compulsory subject for students’ mathematics in the second semester and as general courses for several other major. Calculus II was selected because it is related to other subjects and is the foundation for further understanding of subjects, such as Differential Equations, Real Analysis, Algebra, also for the other subjects that are application. So it’s important to see students in understanding and solving mathematical problems in Calculus II.
In the initial observations which was held on February, 2nd 2016, with correspondents Students of mathematics education regular class C in 2015 amounted to 40 people. There were many students who still difficulty to understand the mathematical problems, so that influent their mathematical problem solving ability. Also found from the initial observation that the ability of students mathematics regular class C 2015 , there was no oversight of thinking activities and monitoring the mathematical problem understanding.
Here is an overview the results of initial observations:

1. The number of students who were in the top group, or high characteristic is 11 people
2. The number of students who were in the group of moderate or medium characteristic is 12 people
3. The number of students who were in the bottom group or low characteristic is 19 people
This percentage is 47,5% of students who are in the lower group shows the lack of students' ability to solve the problems and the lack of awareness of thinking, the lack above oversight of thinking activities and monitoring.Based on the results, the researchers are interested in knowing metacognitive level students and its characteristics in solving problems Calculus II.
1.2 Problem Identification
1. The mathematical problem solving ability is still low.
2. Not aware of the mistake that made in mathematical problem solving. 3. Students are not aware of their advantages and disadvantages in solving

1.7 Operational Definitions
In order to avoid the differences of meaning clarity about important terms contained in this research, the operational definitions will be noted as following:
1. Metacognition is the word that is related to what the learners known about him as individual and how he controls also consciousnees of awareness , consideration and controling or monitoring toward the strategy as well as cognitive processes themselves.
2. Problem solving is how to find alternative solutions to a problem as learners.
105
106
3. Scaffolding questions given in the test should help students in completing the problem and questions always lead to the completion of the work so that measures students' can answer the questions on the test.
5.2 Suggestion
Based on the findings and conclusions on the researchers gave some suggestions are:
1. For students, the problem in mathematical problem solving should use metacognition to guide thinking in mathematical problem solving.
2. For Researches, the subjects of research less attention in though. It’s made
difficulties in research .it’s should be the researcher master in theory deeply
so that can categorize the subject at the level of metacognition.
3. For Lectures, while giving students the material, it’s should always be guided
the students’ thoughts and use the components metacognition in his thinking
