Abstract

Mathematical literacy ability is an ability that can be measured in PISA (Programme for International Student Assesment), one of the contents studied is uncertainty and data (Uncertainly and data). This study aims to describe the learning obstacles experienced by students in uncertainty material content and PISA-based data. This research is a type of descriptive research with a qualitative approach using didactical design (Didactical Design Research) didactic situation analysis stage before learning (prospective analysis). This research was conducted at SMP Pesantren Guppi Samata class VIII with a sample of 16 students using a test instrument in the form of 5 points of description questions and non-tests in the form of observation guidelines. Mathematical literacy indicators used in this study are Communication, Mathematising, Representation, Reasoning and argument, Devising strategies for solving problems, Using symbolic, formal , technical language and operations (Using symbolic, formal, technical and operating language), and Using mathematical tools. The results of this study include: 1) difficulties in understanding the problem; 2) Difficulty in formulating problems; 3) Difficulty in understanding the meaning of the problem; and 4) Difficulty in drawing conclusions. So that the obstacles faced by students are ontogenic obstacles and epistemological obstacles.

Abstract

This study aims to find out: (1) the description of students' mathematical reasoning ability on the material of the two-variable linear equation system, (2) the description of the mathematical reasoning ability of students on the material of the two-variable linear equation system, (3) the influence of mathematical disposition on the mathematical reasoning ability of students on the material of the two-variable linear equation system at SMP Negeri 49 Makassar. This study uses an ex post facto type of research with a quantitative approach. This research was carried out at SMP Negeri 49 Makassar with a population of 136 students in grade VIII which was divided into 5 classes, while the sample from this study amounted to 102 students who were selected using a simple random sampling technique. The instruments used in this study are questionnaires for mathematical dispositions and tests for mathematical reasoning skills. The data analysis techniques used are descriptive statistics and inferential statistics in the form of simple linear regression tests. The results of this study show that (1) the mathematical disposition of grade VIII students of SMP Negeri 49 Makassar is in the medium category. (2) the mathematical reasoning ability of grade VIII students of SMP Negeri 49 Makassar is in the medium category. (3) Based on the partial hypothesis test for the mathematical disposition variable, the value of t-calculation was obtained. (3,493) >,t-table. (1.98) so that it can be concluded that the mathematical disposition variable has a significant effect on the mathematical reasoning ability of students in the material of the two-variable linear equation system at SMP Negeri 49 Makassar.
