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

This study aims to obtain a description of the surface area and volume problem solving profiles of class IX B students at SMP Negeri 1 Lore Tengah. This study uses a qualitative method with a qualitative descriptive approach. The research subjects were 3 students, namely students who had high, medium and low mathematical abilities based on the problem solving steps proposed by Polya. The research results obtained show that: (1) Students who have high mathematical abilities use all stages of Polya in solving problems of surface area and volume of cylinders. (2) Students who have moderate mathematical abilities have not been able to use all of Polya's stages in solving the problem of surface area and volume of cylinders, the stage in question is found in the re-examining stage. However, the subject gave his opinion by explaining using his own language why not re- examine the results of solving the problem given. (3) Students who have low mathematical abilities have not been able to go through all the stages of Polya in solving problems, the subject is only able to go through the stages of understanding the problem but the subject needs to read repeatedly and pay attention to the information contained in the problem repeatedly.

Abstract

The purpose of this study was to obtain a description of the application of the Contextual Teaching and Learning (CTL) approach to improve student learning outcomes in trigonometry comparison materials in class X MIPA-1 SMA 1 Bambalamotu. The type of research used in this study was Classroom Action Research (CAR) developed by Kemmis and Mc. Taggart which carried out consists of 3 stages, namely (1) Planning, (2) the Implementation of actions and observations and (3) reflection. This research was conducted in two cycles. The subjects of this study were all students of class X MIPA-1 as many as 30 students and 3 students were selected as informants with high, medium, and low abilities. The results sgowed that the application of the Contextual Teaching and Learning (CTL) approach could improve student learning outcomes in the Triginimetry Comparison Material of Class X MIPA-1 SMA Negeri 1 Bambalamotu by following the CTL components contained in the learning activities as follows : 1) Contructivism; 2) Inquiry; 3) Learning Comonity; 4) Question; 5) Modeling; 6) Reflection; and 7) Authentic assessment. The results of observation of teacher and student activities also experienced an increase where in cycle I there were still those who got less scores, but in cycle II all aspects that were assessed were getting good and very good ratings. The results of the final action test obtained by the students experienced completeness as many as 13 people and increased in the second cycle, it was obtained that 25 students experienced comletenness.
