[Title: The Students' Understanding of Equal Sign in Completing Mathematics Tasks]. This study aims to describe the student's understanding of the equal sign to solve mathematical tasks. This study was included in the qualitative descriptive study. In this study, the data collected is the data of students work and verbal data (the interview). The subjects were six students of 7th class of MTs Attariqie Malang 2014/2015 (Junior High School), with details of two high-ability students, two students capable of being, and two low-ability students. Students' understanding of the equal sign examined further by providing tests and interviews in six research subjects. Interviews were conducted individually after the students work on the problems individually. The mathematical task load arithmetic and algebra problems. Based on the results of the study, all subjects were able to understand the equal sign as operational and the equal sign as a substitution. For equal sign as the basic relational, only high-ability students were able to understand it. Understanding of medium and low student capable entrenched in the operational pattern that is an equal sign as operational cause confusion to understanding equal sign as the basic relational, eg, 14+11=25+8 where students only pay attention to the results of operations that 14 plus 11 is 25 without notice relation of the addition of 8.

The method of this research was qualitative descriptive. The research subjects were 9 female students and 9 male students of grade IX with high, medium, and low Mathematics ability. The research instruments were test and interview. The research results show that female students with high ability have algebra thinking. Male students with high ability have algebra thinking but indicator of concluding and rechecking was not fulfilled yet. Female students with medium ability have algebra thinking but there was carelessness in the calculation. Male students with medium ability have started to thought algebra but at indicator of interpreting and applying Mathematics findings was not fulfilled yet. Female and male students with low ability do not think algebra yet because all indicators were not fulfilled. This occurred because they still did not understand algebra concept until they could not solve Mathematics problem. Female and male students with high and medium ability who already thought algebra can solve Mathematics problem. However, female and male students with low ability still do not think algebra until they cannot solve the problem.

The law of conservation of mass is a fundamental law and is related to other chemical materials such as chemical reaction equations so that student's learning obstacles of the law of conservation of mass must be overcome. One of the ways to overcome student's learning obstacles of the law of conservation of mass concept is the implementation of sharing and jumping task based lesson design, which is the aim of this research. The research method used is a qualitative descriptive research method. The research subjects were students of X.1 and X.2 SMA in Bandung and chemistry teacher who collaborate with researcher as team teaching. The data on the implementation of sharing and jumping task based lesson design of the law of conservation of mass was obtained from observations, tests, and interviews. Implementation of sharing and jumping task based lesson design of the law of conservation of mass concept was carried out twice. The result of the first implementation is that the previously identified learning obstacles still appear but in a smaller percentage. After the first implementation of the lesson design, it was revised and implemented in other class. The results of the second implementation can overcome student's learning obstacle who think that the mass of solids is heavier than the mass of liquids, but a small number of students still do not take into account the mass of gases in chemical reactions and do not fully understand the meaning of the law of conservation of mass.

This study aimed to analyze students’ errors in problem-solving activities for systems of linear equations. The descriptive qualitative method was adopted and applied to obtain and process the research data. Research subjects were selected using the purposive sampling technique. Three participants were chosen according to their mathematical proficiency levels. Data collection was conducted by tests to measure students’ problem-solving abilities and semi-structural interviews to gather qualitative information about students’ errors in solving systems of linear equations. The interview results were analyzed using narrative analysis to obtain accurate conclusions. The study found that (1) low-ability students tend to perform error at the comprehension stage, (2) medium-ability students are likely to perform error at the transformation stage, and (3) high-ability students tend to perform error at the process skills stage. The solutions based on the ability level are: (1) low-ability students are required to read the question carefully, educators should emphasize the problem-solving procedure, and students should strengthen their understanding of the prerequisite learning content in problem-solving; (2) medium-ability students have to focus on the emphasis and development of their skills in understanding the language of a problem and balance with improving their understanding of learning content and contextual exercising; (3) high-ability students are provided with exercises that can improve their counting speed and accuracy of the subject in resolving a problem.

This research aims to describe the mistakes of the prospective teachers in solving the application of radian measurement problems and their causes. This type of research is qualitative descriptive research with a case study approach. The types of data collection in this research consisted of the results of the subject's work and transcripts of interviews with research subjects. By following the type of data, this research instrument consists of one question about the problem of applying radian measurement and interview guidelines developed by the researchers. Data analysis of the subject's work is carried out by classifying the types of errors to know the types of errors that arise in solving the problem of applying the radian measurements. While the transcript analysis of the interview results was carried out by coding the words to determine the factors causing the errors that appeared. The results of the research indicate that the error in solving the problem of applying the radian measurement are misconceptions and factual errors. This misconception is generally caused by intuitive thinking, while this factual error is generally caused by not paying careful attention to the information in the question. The solution to these errors is to analyze the elements of the circle that are interconnected in solving the problem of applying the radian measurements and to be careful in writing the information that is known in the question.
