<![CDATA[Mathematical reasoning ability is an important ability in helping an individual, in this case the individual does not just remember facts, rules, and steps in solving problems, but reasoning is a skill in making predictions based on his experience. In this article, mathematical reasoning skills will be analyzed on the quadratic function material for grade IX Junior High School odd semester. The goal is to find out such as students' reasoning abilities in studying the quadratic function material. This research is a qualitative descriptive research method with the subject of 28 grade IX students at a junior high school in Cimahi, with various classifications including high, medium, and low-ability students. This is done by giving a test of 5 questions. Then the results are analyzed through data obtained from students' answers to the questions, so that it shows that the achievement of the test with reasoning skills shows that the results obtained by students are still below average.]]>

<![CDATA[This research was conducted with the aim of finding out the errors in the creative thinking ability of MTs students in solving Social Arithmetic problems due to the low level of mathematical creative thinking. This research was conducted by one class VII MTs students in one of the MTs in West Bandung Regency who had implemented the 2013 curriculum. The analytical creative thinking ability has indicators that include fluency, flexibility, originality and elaboration. The data collection technique used is in the form of a 4-question test result in the form of a description of the social arithmetic material, then a description of the errors in each question number. The data analysis carried out is data reduction, data presentation and conclusion drawing. The conclusion obtained from the results of this study is that the creative thinking ability of MTs class VII students in one of the MTs in West Bandung Regency has a fairly creative category and students' mistakes in solving social arithmetic problems are the lack of finding new ideas and using various methods or completion steps and mistakes. in understanding the problem due to a lack of deeper understanding of the material.]]>

<![CDATA[Learning mathematics using the concept of mathematical understanding is needed to solve a mathematical problem. This research is a classroom action research (CAR) which aims to analyze the ability to understand students’ mathematical concepts in SPtLDV material with the help of geogebra media. The subjects of this study were 20 students of class X Senior High School 1 Cisarua with low, medium, and high categories. The instruments used are the initial tests (before the action); the first and second cycle test (after giving the action); interview; observation sheets for teachers and students regarding the research conducted. The resultas obtained in the pre-cycle are 30%, in the first cycle there are 45%, and in the second cycle there are 90% who have the ability to understand students’ understanding of the SPtLDV material. Based on the research that has been done, it can be concluded that the students’ mathematical understanding ability on SPtLDV material assisted by geogebra media has increased.]]>

<![CDATA[This study aims to find out the difficulties of junior high school students in working on descriptive questions on social arithmetic material and to analyze the factors. The subjects of this study were 26 students of class VIII SMP Buana Panca Bakti Cianjur totaling 26 people in the 2019-2020 school year. Data collection in this study was conducted by means of tests, interviews and documentation. Before the interview, a math test was conducted with 5 questions of social arithmetic material. After the tests and interviews are carried out, the results of the tests and interviews are analyzed and taken from the difficulties the students experience when working on social arithmetic questions. The data analysis techniques used in this study were: (1) data reduction, by selecting the main things and focusing the important things, (2) data presentation, presenting the data on student work, (3) drawing conclusions. The results showed that the students' difficulties when solving social arithmetic problems were difficulties in understanding the problems because social arithmetic problems were in the form of story problems, difficulties in mathematical models and difficulties in the process or steps of completion. The factors that cause students' difficulties because students are lazy to read the questions, it is difficult to digest the words and the meaning of the questions, students are less interested in learning mathematics, and students do not understand the arithmetic operation well.]]>

<![CDATA[This research is a descriptive study with the aim of knowing and analyzing the results of student work on questions of mathematical communication skills. This study took the subjects from private junior high schools in Cimahi as many as 25 grade IX students. The data collection technique is by means of test questions, consisting of 5 questions in description with each question representing one indicator of mathematical communication. Based on the data analysis, it was found that the mathematical communication skills of grade IX junior high school students on the curved side of the building material were quite good. Of the 5 indicators of mathematical communication, there are 2 indicators that are classified as high, namely the indicator that states the situation becomes a mathematical model and the indicator interprets the mathematical model into ordinary language. Then 1 indicator that is classified as moderate, namely the indicator that states daily events become a mathematical symbol and 2 indicators that are classified as low, namely the indicator of interpreting and compiling mathematical questions and the indicator of compiling arguments and writing down the reasons.]]>

<![CDATA[This study was conducted based on observations during the implementation of learning during the covid-19 pandemic which showed the low ability of students to master SPLDV materials, considering that it requires independence in studying good self regulated learning. This research aims to analyze the influence of independence in studying science (self regulated learning) on students' mathematical reasoning abilities in SPLDV materials when learning during the covid-19 pandemic. This research was conducted by quantitative methods with a correlational approach. 15 students of class VIII at one of the junior high schools in West Bandung Regency were the subjects in this study. This research was conducted in November during the first semester of the 2021/2022 School Year. Used research instruments are about tests of mathematical reasoning skills, interview guidelines and self regulated learning opinion scales that have been adjusted to their respective indicators. Based on the test results obtained the conclusion that (1) the mathematical reasoning ability of students is influenced by independence in studying the student's self regulated learning. (2) Independence in studying the science (self regulated learning) students positively affect the mathematical reasoning ability of students. (3) The relationship between independence in self regulated learning and mathematical reasoning skills is in a very strong category. ]]>

<![CDATA[The ability to master concepts is one of the obstacles experiences by students in studying algebraic form. This is the background of the author to conduct this research with the aim of knowing the increase in students conceptual mastery if a contextual approach is applied to learning algebraic form in class VII Junior High School of Dharma Kartini Cimahi. The type of research used is Classroom Action Research (CAS) with the methods use are survey, test, and observation methods, the analysis used is qualitative. The results of the stude are evidenced by the improvement in student learning outcomes from the condition of learning completeness that no one reaches the KKM value, increasing in the first cycle as many as 8 students (40%) and in the second cycle it has increased to 15 students (75%). It can be concluded that the application of the contectual approach is good enough to improve students mastery of concepts in algebraic form. ]]>
