Misconception is one of the common problem in understanding the concepts of mathematics and answering questions test of mathematics. Misconseption must be minimalized because the conceptual knowledge is one aspects knowledge within the competency of students of junior high school. Each students has different thinking process in answering questions test of mathematics. There are three stages of thinking process stated by mason whereas entry phase, attack, and review. Thus, this study was aimed to describe misconception in answering algebra question of eightth grade student based on masons' thinking process. The subjects of this research were two students of grade eight chosen based on the result of test of understanding concept completed by CRI. The result of this study shown that based on the thinking process stated by mason, students experinced misconception only at phase attack when equalling the denominator, algebra manipulation and operational of equal tribe.

In a studying, involving students in finding a material concepts of mathematics, students will be easier to understand the material. The material studied mathematics in real-world objects with the involvement of primary school students to pay attention to students' cognitive load. Through the guidance of teachers, students will be easier to find a concept. In this paper discussed the development of the RPP and LKPD based Realistic Mathematics Education by taking into account the students' cognitive load material simple geometry fourth grade. The model of development used Plomp models with five phases. The results of development RPP and LKPD is valid, practical and effective.

This study aims to determine the representation of children in kindergartens of the objects and symbols of numbers 1 to 10 when playing activities. So the mathematical activity in appropriate with the child's development. This study uses qualitative descriptive by Moleong. The collection of data through observation, interviews, photo and recording. To check the validity of researchers used data triangulation of data sources, theory and methodology. Results of the study is that children need visual in process representation. They need to understand the concept of visualization when many objects, counting objects, understand the numbers 1 to 10. Children are not able to think abstractly. Representation of children has not been perfect. Method of learning in kindergarten helps learning to count and recognize numbers. Especially if done with playing.

This study was implemented at one of the State Junior High Schools in Pamekasan Regency, Madura by online in April 2020. The instruments in this study were a cognitive style questionnaire, test questions and interview quides. Subject were selected by giving The Cognitive Style Inventory. From the results of the questionnaire, 1 female student who has an intuitive cognitive style was selected as the subject. This study was conducted by giving 2 mathematical problems that have been validated by 2 supervisors and a validator. Then proceed with conducting interviews with the subject. Subject’ answers were than analyzed using Polya’s completion step and thinking process through the APOS stages. The results showed that female students with an intuitive cognitive style solved the problem is not detail step by step. Subject have gone through the action, processes, and schemes stages in solving mathematic problems.

The purpose of this qualitative descriptive research is describing the errors of concepts and procedures by four different thinking styles students in solving equations problem. This research was conducted on 183 students from six classes of Mathematics and Natural Sciences program. Results showed that error of exponential concept and logarithm concept in all thinking styles, misconceptions of linear equations in three thinking styles and misconception of quadratic equations on one thinking style. Similarly, errors are found for procedures of integer count operation for each thinking style, variable permissive in three thinking styles and solving of exponent and logarithmic equations in one thinking style.

This research was aimed to know the difference of understanding the concept and motivation of student learning which is taught by Think Pair Share model in the experimental class and the students who are taught by the group work model in the control class. This study used quasi experimental design with nonequivalent control group design using pretest-postest test scores. Research data obtained through test and motivation questionnaire in the form of statement. The results showed that (1) there is a significant understanding of concept concepts between students who learn through Think Pair Share learning with students who learn through cooperative learning without syntax, (2) there is a difference of understanding of the concept significantly between high motivation and low motivation students, and (3) interaction between learning model and learning motivation to understanding student concept.

This research was aimed to describing the mistakes made by the eighth grade students of SMPN 2 Tiris in Probolinggo district in solving the story problems related to the Pythagorean Theorem. Three subjects were selected to solve the story problem of the Pythagorean Theorem then interviewed. The analysis used was based on conceptual error, procedural and calculation. The results showed that in the conceptual stage the subject made a mistake in drawing a right triangle and determining the sloping side. Procedural errors are made, namely the subject makes a withdrawal of the root in the right segment even though in the left side is still a square. While at the calculation stage the subject made a mistake in determining the results of the square root and the difference so that it was wrong in the final result.
