One thing that students must master to achieve learning goals is mathematical reasoning abilities. In other words, students can use mathematics as a reasoning tool both in learning mathematics in class and everyday life. This research aims to determine the difference between students' mathematical reasoning abilities and low learning interest. Good student learning interest will make students happy to learn mathematics without coercion, with good learning interest will affect students' mathematical reasoning abilities. Mathematical reasoning abilities can be improved through increasing student interest in learning. This research is a qualitative descriptive study, the population in this study were all eighth-grade students of the 2020/2021 academic year. The sample taken was class VIII.2 using a random cluster. Data collection techniques and research instruments are tests of mathematical reasoning abilities on quadrilateral material, questionnaires in questionnaire sheets for learning interests, and interviews. Based on the results of data analysis, it can be concluded that: 1) There are differences in mathematical reasoning abilities between students who have high learning interests. 2) There are differences in mathematical reasoning abilities between students with low interest in learning.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123666385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method of this study is a qualitative descriptive research method. This study was conducted at Junior High School in Kampar. The subjects of this study were students of seventh grade in the 2020/2021 academic year as many as 20 students. The data analysis was carried out in three stages: data reduction, data presentation, and concluding. The data from this study were obtained by providing 5 items of mathematical problem-solving ability, distributing a questionnaire about self-confidence using a Likert scale in the form of a checklist, and conducting interviews. The results showed that there was a relationship between students' self-confidence and mathematical problem-solving abilities. From the questionnaire score category and the results of the problem-solving ability test given, it can be seen that 25% of students who have high self-confidence have good problem-solving skills because they meet all problem-solving indicators. Sixty percent of students who have moderate self-confidence have fairly good problem-solving abilities because they only meet part of the 4 problem-solving indicators. Fifteen percent of students belonging to the low category of self-confidence have problem-solving skills that are not good enough. The findings of this study can motivate teachers to raise students' self-confidence because students who have good self-confidence have good problem-solving abilities as well. The study's findings suggest that teachers should use methods and techniques to boost students' self-confidence in mathematics learning.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122403828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the ability analysis carried out by students in working on mathematical problem-solving questions with Linear Equations and Inequality One variable found that the student problem-solving process is very low. The instrument used is a question that has been tested for reliability, validity, discriminating power, and difficulty. Generally, the achievement of indicators of problem-solving ability has not been fully achieved due to ineffective learning and lack of interaction between teachers and students.

Therefore, teachers must understand the learning process, must be aware of the learners’ psychologies, and capable of developing the learners’ interest so they have greater spirits to learn. From various problems of teaching mathematics, the teacher's position is the center of the problem. Teachers as motivators, educators, and supervisors have important roles to direct learners to be capable and to actualize them in real life through the school lessons. There are several factors of difficulties experienced by mathematics teachers in implementing learning at SMAN 2 Tambang. This research aims to determine the difficulties experienced by mathematics teachers in implementing learning. This type of writing uses a descriptive qualitative approach. The subjects of this research were teachers at SMAN 2 Tambang. Data collection techniques used interviews and questionnaires. It could be concluded that the most common difficulty was determining the learning media and learning process planning. The cause was the limitation of facilities, infrastructures, and unfordable media by the learners. On the other hand, the next difficulties were due to the large number of learners that could not be accommodated in a small classroom.","PeriodicalId":137292,"journal":{"name":"Journal of Research on Mathematics Instruction (JRMI)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123403852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test questions are given in the form of 7 description questions.
