Abstract

This study aims to describe the problem-solving abilities of students reviewed from their self-confidence. 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.

Abstract

The objective of this study was to analyze the mathematical problem-solving abilities of class XI high school students in solving sequence and series questions. This research is a descriptive study that aims to describe the mathematical problem-solving ability of class XI students in solving problems of sequences and series. The population in this study were students of class XI SMA in the academic year 2020/2021. The sample was selected by purposive sampling obtained students XI MIPA 1 totaling 25 students. The data was obtained from the results of the mathematical problem-solving ability essay test on the material of sequences and series as many as 4 questions taken from the 2018 National Examination questions. The purpose of this study was to determine and analyze students' mathematical problem-solving abilities on the material of sequences and series. From the results of the study, it can be concluded that the mathematical problem-solving ability on indicators 1, 2, and 3 are categorized as medium and high. In accordance with the research method, students are categorized as having low mathematical problem-solving abilities if they obtain medium, high, and very high criteria. The percentage of indicator 1 is 68.75%, the percentage of indicator 2 is 55.75%, the percentage of indicator 3 is 62.2% while the percentage of indicator 4 is 34.75.

Abstract

The Covid-19 pandemic has greatly impacted various worlds without exception in the field of education, especially in Indonesia. This situation causes learning that is usually done face-to-face to turn into online learning making students find it difficult to understand the material given. This study aims to determine the mathematical problem-solving ability of MTS Thariqul Hidayah students, Indragiri Hulu Regency in class VII MTS Thariqul Hidayah students as many as 25 students and to describe the level of problem-solving ability categories in each item statement of questions that have been given in the form of descriptive questions consisting of 5 questions. The research method uses qualitative descriptive analysis to find out the extent to which the category achievement is based on problem-solving indicators during the covid-19 pandemic. 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. The results showed that there were still student errors in solving mathematical problems in each problem-solving indicator.

Abstract

This article describes applying the Problem-Based Learning (PBL) model on Mathematical Communication Ability. The research in this journal is an experimental study using pretest-posttest control group design with a population of seventh-grade students of SMP Negeri in Kuantan Singingi Regency, divided into three school levels: high, medium, and low schools. From each school, two classes were randomly selected as the experimental class and the control class. The research instrument was the Mathematical Communication Ability test questions. The data collection technique is done by testing. Data were analyzed using t-test and one-way ANOVA. The results showed an effect of PBL application on mathematical communication skills in terms of all students. The effect of PBL application on mathematical communication skills in terms of school-level shows that for the high school level, students are better than students using conventional learning, while at the medium and low school level, there is no significant effect.

Abstract

This study to investigate whether there are differences in mathematical communication skills between students who take Think Pair Share learning and students who follow conventional learning when viewed from the learning motivation of students at SMP Negeri 4 Tambang. This study is a quasi-experimental study that aims to investigate a causal relationship by giving treatment to one class and comparing the results with one class that is given a different treatment. The subjects in this study were students of class VIII-G and class VIII-E of SMP Negeri 4 Tambang and the object of this research was the influence of the application of the Think Pair Share learning model on students' mathematical communication skills in terms of learning motivation. The data analysis technique used by the researcher is t-test, correlation (Product Moment), and two-way ANOVA. The instrument used is a description test to measure students' mathematical communication skills, and a questionnaire to measure the level of student motivation. Based on the results of the study, it was concluded that (1) there were differences in communication skills between students using the Think Pair Share learning model and students using conventional learning models (2) there were differences in student motivation in the experimental class and the control class (3) there was a contribution between learning motivation and metamatic communication. . (4) there is no interaction between the learning model and student motivation on students' mathematical communication skills. Thus, in general, the Think Pair Share learning model has an effect on mathematical communication in terms of student motivation at SMP Negeri 4 Tambang..

Abstract

This research .is.motivated. by the. existence of. facts. in the.field.which. show.the.low.mathematical.reasoning.skills found in students at SMP Negeri 16 Pekanbaru. 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.
