Abstract

Abstract This research aims to describe the forms of student misconceptions and the factors that cause misconceptions experienced by students in solving linear inequality problems with one variable containing absolute values in class X SMA Muhammadiyah 1 Pontianak. The subjects of this research were students of class X IPA 3 SMA Muhammadiyah 1 Pontianak, totaling 25 students. The research uses descriptive method as the research method. Case study is a form of research used. The results of the research revealed that the research subjects experienced five forms of misconception, namely notation misconceptions experienced by 1 student or by 4%, generalizing misconceptions experienced by 3 students or by 12%, misconceptions of the application of rules experienced by 6 students or by 24%, calculation misconceptions experienced by 2 students or by 8%, and specialization misconceptions experienced by 3 students or 12%. The misconceptions experienced by these students are caused by wrong intuition and incomplete reasoning, where students' intuitive thoughts that arise spontaneously when solving problems are still wrong and students' reasoning or logic is still wrong in drawing conclusions and being too broad in generalizing. Keywords: Misconceptions, Two-Tier Diagnostic Test, One Variable Linear Inequality Problem with Absolute Values

Abstract

Nowadays, there are several universities in West Kalimantan that have mathematics education department, such as IKIP Pontianak, STKIP Singkawang, and STKIP Sintang. This condition provides great opportunities for prospective students who want to become mathematics teachers in schools, especially high schools. On the other side, the presence of mathematics education department in several universities in West Kalimantan is a challenge for Mathematics Education department FKIP Untan. One of the challenges that come is how to produce graduates who can compete in the world of work. In order to create qualified mathematics teacher candidates, it is very important for the FKIP Untan mathematics education department to provide one of the quality final assignment guidance services so that final year students can have quality final projects. This study will examine how high the level of student satisfaction with final assignment guidance services in Mathematics Education Department FKIP Untan. Furthermore, it will be known what service items should be improved and developed in an effort to increase student satisfaction. The level of student satisfaction with the final assignment guidance service is 0% of students are not satisfied, 0% of students are not satisfied, 9% of students are satisfied, 30% of students are quite satisfied, and 61% of students are very satisfied. It can be concluded that the final year students of the Mathematics Education Department, Teaching and Education Faculty, Tanjungpura University are satisfied with the services provided by the supervisorsKeywords: Satisfaction; academic services; final assignment guidance.

Abstract

This research aimed to describe mathematical communication skills, mathematical resilience, and the relationship between mathematical communication skills and mathematical resilience. This research used a quantitative approach with a correlation research design. The population in this study were students of grade XI SMA Negeri 2 Teluk Keramat and the sample was students of grade XI MIPA 2.The results showed that the mathematical communication skills students tend to have is the ability to express mathematical concepts by stating daily events in language or mathematical symbols (mathematical expression ability) which were able to be achieved by the students as much as 62%. Whereas for mathematical resilience that students tend to have is to have curiosity, reflect, research, and make use of various sources in mathematics learning, which contributed 38.7% and were able to be achieved by 16 students (76%). Furthermore, based on the results of the Pearson Product Moment correlation test, a significance value of 0.021 and a correlation value of 0.500 was obtained. So it can be concluded that there is a significant relationship between mathematical communication skills, mathematical resilience, and the strength of the correlation between the two variables is classified as moderate. Keywords: Correlation, Mathematical Communication Skills, Mathematical Resilience

Abstract

Nowadays, there are several LPTK in West Kalimantan that have mathematics education courses apart from FKIP UNTAN. This is a challenge for FKIP UNTAN to become the main choice for prospective students. So, it is very important for the FKIP UNTAN mathematics education department to provide quality academic services to students so that they feel satisfied. One of the student satisfaction assessments index in academic services in the Mathematics Education Department of FKIP UNTAN is academic guidance and course implementation. This study will examine how high the level of student satisfaction with academic services in the Mathematics education Department FKIP UNTAN . Furthermore, it will be known what service items should be improved and developed in an effort to increase student satisfaction. The method used is descriptive method with a survey form involving students in 3rd, 5th, and 7th semester. The instrument used is a satisfaction questionnaire. The level of student satisfaction with academic guidance services is 2% of students are not satisfied, 6% of students are not satisfied, 30% of students are satisfied, 32% of students are quite satisfied, and 30% of students are very satisfied. Then for the level of student satisfaction with the lecture process as much as 2% of students were not satisfied, 5% of students were not satisfied, 27% of students were satisfied, 36% of students were quite satisfied, and 30% of students were very satisfied.Keywords: Satisfaction; Academic Services; Academic Guidance; The Lecture Process.

Abstract

The importance of problem solving skills is based on the results of the Trends in International Mathematics and Science Study (TIMSS) survey which means that students' mathematical problem solving abilities in Indonesia are still in a very low category. Where one factor in the low problem solving ability of students is the low numerical ability of students. Based on these results, researchers are interested in revealing deeper results regarding students' numerical abilities in solving mathematical problems. Thus, this study was conducted with the aim of knowing students' numerical abilities in solving mathematical problems. The method used in this research is descriptive method. With the form of descriptive quantitative research, the subjects in this study were students of class XII MIA MA Khulafaur Rasyidin and the object of this research was numerical ability in solving mathematical problems. The data collection technique used a test technique with the data analysis technique used, namely the average percentage. The results of data analysis showed that the numerical ability of students in solving mathematical problems was included in the medium category with the percentage obtained at 58.428%. Which means that overall there are still students who are not fast and careful in doing arithmetic calculations when solving problem solving problems properly.

Abstract

This research was based on the results of pre-research showed that students’ problem-solving abilities were still low, especially in comparison materials. Problem-solving abilities can be influenced by many factors, one of which is adversity quotient. One of the first steps that can be done to explore students’ problem-solving skills is to discuss how the problem-solving abilities that students currently have. The goal of this research is to know and to describe students’ problem-solving skills in comparison materials in class VII. Descriptive method is used in this study. The students of class VIII C of SMP Negeri 1 Teluk Keramat for the 2021/2022 school year were the subject in this study. Then they were sampled by 3 people from the climber type ada 3 people from the camper type. The data.collection.tools.in.this.study are subjective written tests in the form of essays and interview guidelines.
