Abstract

The purpose of this research was to obtain a description of the mathematical representation of class VIIJ students of SMP Negeri 9 Palu in solving line and angle problems. This type of research is descriptive-qualitative. The research subjects consisted of 3 students, namely 1 student representing low ability, 1 student representing moderate ability, and 1 student representing high ability, based on the grades of even semester report cards for the 2021/2022 academic year. Collecting data using tests and interviews. In analyzing data, researchers used data reduction, data display, and conclusion drawing/verification. The results showed that subjects with low abilities had mathematical representation abilities in solving line and angle problems in problem number 1 but in solving problem number 2 they were still not good. This means that the subject meets the indicators of mathematical representation abilities which include image representation, verbal representation, and symbolic representation which are still not good. Subjects with moderate abilities have mathematical representation abilities in solving line and angle problems in question number 1 but in solving problem number 2 they do not show image representations. This means that the subject meets the indicators of mathematical representation which includes image representation, verbal representation, and symbolic representation quite well. Subjects with high ability have mathematical representation abilities in solving line and angle problems in questions number 1 and 2. This means that the subject fulfills all indicators of mathematical representation ability which include image representation, verbal representation, and symbolic representation well.

Abstract

The purpose of this study is to profile the mathematical connection ability of students who have high mathematical abilities in the sub-topic of trigonometric equations. The research design uses a qualitative approach. The study was conducted on students of St. Andreas Palu Catholic High School. The instruments used are written assignments and interview guidelines. The results of this study show that the connection ability  of students with high mathematical ability in solving equation problems in each category includes: 1) In  the modeling connection  category, students know the information in the problem completely and precisely this is characterized by  recognize the relationship between time and trigonometry so that students can use the formulas they know to determine when the right time is so that the ship can enter the port based on known equations. 2)  In the concept connection category, students understand the concept of trigonometric equations and trigonometric comparisons in solving trigonometric equation problems. However, the subject did not understand well the interrelationship of the concept of cosine trigonometric equations with the given question so that an incorrect final answer was obtained.  3) In the category of procedure connections, students relate concepts through appropriate procedures so that they can solve trigonometric equation problems.
