Abstract

As a subject that is considered difficult, it causes some students to be less motivated in learning mathematics. This is marked by a lack of enthusiasm and less active students to take PBM in class. In addition, the lack of problem solving skills makes students only able to solve problems based on the examples given. This is evidenced by the percentage of test scores of students who have not reached the KKM more than 75%. This study aims to determine the improvement of problem solving abilities and students' motivation to learn mathematics with the application of problem solving methods. This research uses Classroom Action Research (CAR) in two cycles consisting of design, activities and observations, reflection, and revision. The research subjects were students of class IX-1 MTsN 28 Jakarta. The data were obtained from the results of student motivation questionnaires, formative test results, and observation sheets for teaching and learning activities. The data were analyzed descriptively qualitatively by using an analytical technique framework consisting of data reduction, data presentation, and drawing conclusions. The results showed that the average value of students' mathematical problem solving abilities increased from the first cycle of 61.05 to 75.97 in the second cycle. The number of students whose scores are above the KKM also increased from 47.32% in the first cycle to 83.3% in the second cycle. Likewise, the number of motivated students increased for the medium, high, and very high categories from cycle I to cycle II. The conclusion of this study is that problem solving methods can improve motivation and mathematical problem solving abilities of students in class IX-1 MTsN 28 Jakarta.

Abstract

The ability to understand concepts is one of the skills that must be mastered by students in mathematics. However, the ability to understand the concepts of MTsN 28 Jakarta students is still relatively low. The existence of the implementation of PTM Limited (PTMP) resulted in learning only being a process of transferring formulas and uploading assignments. Therefore, we need an innovation that can make learning more meaningful. PMRI can be a solution so that students are involved in learning. To overcome time constraints, PMRI can be implemented with the help of the Learning Management System (LMS) application. The purpose of this study was to find out the application of the PMRI approach assisted by the LMS application in improving the ability to understand the concept of Building Flat Sided Spaces in class VIII-2 students of MTsN 28 Jakarta. This study uses a qualitative approach with the type of Classroom Action Research (PTK) which is carried out in three cycles. The research subjects observed in the study were 6 students from the upper, middle and lower groups. Data analysis refers to the achievement of indicators of understanding the concept as seen from the results of the research subject's test answers through three stages, namely: data reduction, data presentation, and drawing conclusions. The results showed that the average test score increased from 69.97 in cycle I, 73.06 in cycle II, and 78.18 in cycle III. Students who reached KKM also experienced an increase, in the final test of cycle I there were 7 people (23.33%), in cycle II it increased to 16 people (50%), and in cycle III again it increased to 23 people (76.67%) . The increase in test scores is also supported by the addition of concept understanding indicator scores. Thus, it can be said that the PMRI approach assisted by the LMS application can improve students' understanding of mathematical concepts.

Abstract

Abstract This study aims to determine students' analytical abilities in the matter of quadratic function graphs as well as learn the learning of quadratic function graphs integrated with Islamic values at MTsN 28 Jakarta. This Classroom Action Research was conducted in 2 cycles on Quadratic Function Graph material. Each process consists of planning, implementing, observing, and reflecting. Through research, qualitative data on mathematics learning integrated with Islamic values were collected using observation techniques, interviews, field notes, and quantitative data analysis ability test results. Qualitative data was processed using a four-step qualitative analysis method: data collection, data reduction, data presentation, and conclusion, while the quantitative data were processed using descriptive statistics. The results showed that the student's analytical abilities on the quadratic function graph material integrated with Islamic values developed well. An analogy between the effects of the x2 coefficient, x coefficient, and constant values on the shape of the graph teaches the material for graphing quadratic functions integrated with Islamic values. Islamic values that appear based on students' analytical abilities on changes in the form of the quadratic function graph are the concepts of faith, lust (desire), and charity (deeds). After learning the quadratic function graph integrated with Islamic values, the measurement results increased the analytical ability score from the average value and the percentage of student learning completeness. With the results of this study, it is recommended that mathematics learning is integrated with Islamic values as a learning approach that can improve students' mathematical analysis abilities.   Abstrak Penelitian ini bertujuan untuk mengetahui kemampuan analisis siswa pada materi grafik fungsi kuadrat sekaligus mengetahuipembelajaran grafik fungsi kuadrat yang terintegrasi nilai-nilai keislaman di MTsN 28 Jakarta.
