Abstract

Problems in learning mathematics that are often encountered include the inability of students to understand correctly the subject matter being taught resulting in the achievement of student learning outcomes being less than optimal. The purpose of this study was to describe the results of the analysis of the difficulties of class X SMK students in solving root form problems. The research method used in this study is a qualitative descriptive method. The subjects of the study were 13 students of class X at SMK 4 LPPM RI. The research instrument consisted of three root form test questions. The data collection technique used in this study was in the form of test results. The results of the study indicate that students' mastery of the material is above 70% so it can be said that students have no difficulty in solving problems. However, students still have difficulty understanding the concept of root form and errors in calculations. From the results of the analysis, it can be concluded that class X SMK students in solving root form problems in calculating the final settlement, while for indicators determining the concept of rationalizing root forms, it is above 70%.

Abstract

Era Society 5.0 which has a significant impact on various aspects, including education. Era Society 5.0 must have faced by producing competent and globally competitive human resources. Mathematics teachers candidate need to be provided with literacy skills so that it makes them easier to understand and process the information obtained to solve problems as well as numeracy skills to develop knowledge and skills to use mathematics confidently in all aspects of life. To answer these challenges, it is necessary to implement learning media, namely IMATIC (Interactive Mathematic Comic) based on VBA-Excel which is interesting, simple, educative and easy to understand. The research method uses descriptive research with test instruments, questionnaires and interviews. The results of the study show that the implementation of IMATIC can make mathematics teachers candidate have good literacy and numeracy skills. In addition, it is effectively used in learning because they understand the material by being carried away in the story so that it is easy to understand.

Abstract

The purpose of this study was to see the improvement of students' mathematical problem-solving ability after implementing of the Creative Problem Solving (CPS) learning model. The research method used quantitative research with a quasi-experimental design. The population of this study was all students of class VIII of SMP PGRI 5 Cimahi. Two classes as research samples were selected through the Cluster Random Sampling technique, where one class was the experimental class and one class was the control class. The instrument used was a mathematical problem-solving ability test instrument in the form of a description of 5 questions arranged based on indicators of mathematical problem-solving ability. Data processing used the normality test and the Mann-Whitney test. The results of this study were an increase in students' mathematical problem-solving ability who implemented the Creative Problem Solving (CPS) learning model better than those who used conventional learning.

Abstract

This study aims to assess the effectiveness of the Problem Based Learning (PBL) approach in enhancing junior high school students' mathematical critical thinking skills on the topic of ratios. The subjects of the study were students from SMP IT Nur Al Rahman Cihanjuang, divided into two classes. One class, comprising 21 students, served as the experimental group and received instruction through the Problem Based Learning (PBL) approach, while the other class, also consisting of 21 students, served as the control group and received conventional instruction. The instruments used included interview sheets, documentation studies, student response questionnaires, observation sheets, and a test of mathematical critical thinking skills with 5 essay questions. The data obtained from the pretest and posttest were analyzed using inferential and descriptive statistics. The study's findings indicated that the Problem Based Learning (PBL) approach was more effective in improving the mathematical critical thinking skills of junior high school students on the topic of ratios compared to conventional teaching methods. Consequently, there was an improvement in the mathematical critical thinking skills of students using the PBL approach compared to those using conventional teaching methods.

Abstract

This study aims to study and analyze the improvement of mathematical problem-solving skills in students who use the Contextual Teaching and Learning approach. This research is a type of quasi-experimental research with the population of grade VIII students at SMP Negeri 2 Batujajar and the sample of this study is students of grades VIII B and VIII C. The data collection instrument in this study uses mathematical problem-solving ability test questions in the form of descriptions of five questions. Quantitative data processing used the analysis of 2 dependent samples with a normality test and continued with a paired t-test. The results of this study are: Improvement of mathematical problem-solving ability of junior high school students in grade VIII whose learning uses the Contextual Teaching and Learning approach is better than those who use ordinary learning in Pythagorean Theorem material because in their learning they use all the characteristics of CTL, so that they can train students to solve a problem presented.
