Abstract

Academic achievement of students of SMP Negeri 4 Cibinong in Mathematics for the 2021-2022 academic year using the Problem Based Learning learning model is not satisfactory. This proves that students still do not understand the stages in working on the questions. Another reason is that students are still not familiar with the PBL method compared to conventional methods. The aim of this research is to analyze the level of ability of students when they solve problems, especially in mathematics problems with algebraic material through the use of Problem based learning models. This research method is descriptive and aims to present a sign, phenomenon, or event in the present. Through descriptive research, researchers describe events and events that have a role as center and attention. The result that can be taken is the low problem-solving ability of students at SMP Negeri 4 Cibinong. There are several types of errors when solving problems in algebraic material. 46% ability to understand problems, 40% ability to make plans, and 0% ability to complete plans 16% ability to recheck solutions. Usually students with conventional learning result in students depending on educators or teachers then they experience a decline to solve problems. If the teacher familiarizes the Problem Based Learning learning model, students' problem-solving abilities will increase and learning will not be teacher-centered.

Abstract

Learning style is a method used by each individual to absorb information easily and quickly. Learning style is one of the supporting factors related to mathematical literacy ability. This can happen because learning styles can affect learning outcomes and student achievement. In this study, the learning style used is the VAK learning style (Visual, Audiotori, Kinesthetic). The purpose of this research is to describe how students' mathematical literacy skills at VAK learning style. Selected 1 student who has the highest score on the visual learning style, 1 student who has the highest score on the auditory learning style, and 1 student who has the highest score on the kinesthetic learning style. The results obtained from this study are students with the highest visual learning style can complete level 1 correctly. at level 3 and 4 students with the highest visual learning style came to the indicators of translating problems. Meanwhile, students with the highest auditory learning style were only able to complete level 3 correctly. Meanwhile, students with the highest kinesthetic learning style can complete level 1 correctly. At level 3 only errors occur when drawing conclusions. So it can be concluded that students with the highest visual learning styles can achieve higher competencies than students with auditory and kinesthetic learning styles.

Abstract

Learning difficulties are external factors that have an impact on the low learning outcomes of students in mathematics. Another element that adds to learning difficulties is the lack of enthusiasm (motivation) for learning and makes students reluctant and lazy to learn mathematics. The reasons for carrying out the analysis of this study include finding, identifying and assessing learning difficulties faced by class VII students at SMP Negeri 1 Cililin, as well as students' mistakes when working on set material questions. The method used in this research is by using descriptive qualitative method. Participants in this study were 18 students. The approach of collecting data in this research is by giving a test test of three questions in the form of a description. Based on the money study that has been carried out, there are several aspects of learning difficulties including although most students already understand the concept of the set, they still experience some learning difficulties, such as not being able to understand the problem, not being careful in recording the members of the set, and having difficulty in making the required mathematical model.
