This study aims to describe the sociomatematical norms that are owned by students when learning mathematics in class. The subjects of this study were students of class VII-A Jakarta 113 Junior High School. The research method used is descriptive qualitative method. This research uses sociomatematical norms questionnaire and interview. Based on the results of the study, there were 9 students who had very good sociomatematical norms categories with a total percentage of indicators of 81% and there were 14 students who had good sociomatematical norms categories with a total percentage of indicators of 72%. The results showed that very good sociomatematical norms owned by students would affect the high results obtained by students in mathematics learning and good sociomatematical norms would affect the moderate and low results obtained by students in learning mathematics.

Before And After

Learning mathematics is not only aimed at developing mathematical cognitive abilities, but also for developing affective domains. One important aspect in the affective domain that is very influential and determines success in learning mathematics is the positive view of students on mathematics or in mathematics learning called mathematical disposition. A student who has a high disposition will be more persistent and resilient in facing mathematical problems that are more challenging and will be more responsible for their own learning and always develop good habits in mathematics. The problem posing approach which in the learning process requires students to ask questions and make their solutions is expected to be able to change students 'views of mathematics to be more positive, while also improving students' mathematical abilities. This study aims to examine the differences in the levels of mathematical disposition of junior high school students before and after learning through the problem posing approach. The type of research is experimental research with the design of one group pre-test post-test design. The population in this study were all VII grade students of Bandar Baru 1 Junior High School, with research samples of class VII2 students selected through random sampling techniques. The instrument used to obtain the research data was a mathematical disposition scale questionnaire sheet. The statistical test used to analyze data on differences in mathematical disposition of junior high school students before and after learning through the problem posing approach is paired t-test. The results showed that there were significant differences in the level of mathematical disposition of junior high school students before and after learning through the problem posing approach. This means that students' mathematical dispositions get better after they get a problem posing learning approach. Keywords: Mathematical Disposition, Problem Posing Approach

<div><p class="1eAbstract-text">The success of students learning Mathematics at “X” Junior High School is very low. Alike success of students learning Mathematics, the students also have low motivation, low self-esteem, and low self-confidence. According to this fact, guessed that there is correlation between motivation and success of students, between self-esteem and success of students, and between self-confidence and success of students learning Mathematics, so needed a research to see that correlation. Research method that was used to see that correlation is correlation method, with questionnaire as a tool to collect data from 131 students of “X” Junior High School. Technique used to analyze data are statistical techniques, which are descriptive and inferential statistic. The conclusions are 1) there is a significant correlation between motivation and success of students learning Mathematics at “X” Junior High School, 2) there is significant correlation between self-esteem and success of students learning Mathematics at “X” Junior High School, and 3) there is significant correlation between self-confidence and success of students learning Mathematics at “X” Junior High School.</p></div>

This study aims to make a contribution related to opinions and perceptions about negative exponents among junior high school students. In this study, negative exponents are considered as difficult things that require various efforts to instill good knowledge concepts in students. One of them is through evidence in learning mathematics. Evidence is considered capable of instilling students' knowledge concepts in negative exponent material. The research method used is descriptive qualitative research. Descriptive literature research studies through literature reviews, journals, and books relating to negative exponents. The results of this study are alternatives to completing formal and informal evidence related to negative exponents in junior high school students. Through some alternative evidence in introducing negative exponents is expected to make students better understand the form of negative exponents well. So that at the level above students can easily solve problems related to negative exponents without getting errors in the operation of advanced exponents.
