A domain of learning, understanding is an absolute prerequisite for improving cognitive abilities. Leveling the mental model of students is one way in which a teacher can review the extent to which students understand based on their respective levels. The purpose of this study was to describe the six degrees of student's mental models in understanding the concept of using the Pythagoras theorem in junior high school students. The method used in this study is a qualitative research method. The subjects in this study amounted to 61 students who were a combination of 30 students of class VIII A and 31 students of class VIII B. The two classes of subjects were taken so that the six levels of the mental model were founded. The sixty-one items test questions were given. Each of the representatives of mental models who found the criteria was selected, namely two students to be interviewed so that 12 students were interview respondents. To ensure the validity of the data, researchers analyzed the data in two ways, namely data source triangulation and method triangulation. The results of the study showed a description of each level of the student's mental model in understanding the concept of using the Pythagoras theorem.   Suatudomain belajar, pemahaman merupakan prasyaratan mutlak untuk meningkatkankemampuankognitif.  Pelevelan model mental siswa merupakan salah satu cara dimana seorang pengajar dapat meninjau sejauh manakah pemahaman siswa berdasarkan tingkatan masing – masing.

The article is devoted to the role of increase of junior schoolchildren’s cognitive activity as an important condition for the development of cognitive abilities of  learners.  Psycho-pedagogical  support  should  be  focused  on  the  development of cognitive functions of junior schoolchildren, and psychologists and parents should be involved in this process, as well as the teachers. Traditionally, psycho-pedagogical support at primary school focuses on the child's adaptation to the new educational environment.  We  consider  that  a  child  needs  the  same  support  in  the  process of mastering  the  curriculum.  There  is  no  true  support  without  an  emotional involvement and empathy, and as a result cognitive activity of a child might suffer greatly. It was proven by empirical results obtained in an ordinary school, where no innovative teaching methods are used. At the end of primary school pupils have a significantly reduced motivation, teachers express no serious interest in problems of junior high school students. Not entirely satisfactory educational environment also could not provide a positive influence on the development of cognitive sphere.

This study is a quasi-experimental research, which aims to examine the achievement and improvement of problem-solving skills of mathematics and the independence of junior high school students learning through a realistic approach. The population in this study is all students of class VIII SMPN 4 Subang. Samples were taken by random class, obtained two classes of class VIII H as the experimental class and VIII.F as control class. The instrument in this study is a set of mathematical problem-solving test and a set of learning independence scales. The study found that the achievement and improvement of students' mathematical problem-solving ability and the independence of student learning whose learning using realistic learning are better than that of learning using ordinary learning in terms of the initial ability level of students. There is an interaction of mathematical problem-solving abilities between students whose learning uses a realistic approach with a student's initial ability level. Meanwhile, there is no interaction between realistic learning with the level of initial ability of students in generating student self-reliance. Besides, there is no association between mathematical problem solving ability and student learning independence, both in class that use realistic and classroom learning using ordinary learning. The picture of student's performance during realistic learning is more active, it shows the involvement of students both individually and in collaboration with the group, so that it can improve the problem solving ability of mathematics as well as student's learning independence. The description of the students' difficulties in solving the problem of mathematical problem solving ability lies in the indicator about number 5 which is about making the mathematical model because of the lowest percentage indicator.
