Abstract

The use of important teaching materials in the implementation of learning. This research also aims to support mathematics learning to be more interactive and effective and to support student activities in the learning process to improve well. Student learning outcomes also focus on students’ mathematical critical thinking skills. Therefore, the purpose of this study was to determine the effectiveness of mathematic teaching materials on mathematical critical thinking skilss. The research method used in this study is experimental research, namely those obtained from observations, questionnaires and tests. The participants in this research were grade VI students of SMPN 2 Kertasari which consisted of 2 classes. The data analysis used in this research is descriptive analysis. The results of the study show three parts of effectiveness, namely the effectiveness of interaction showing 61% results with a moderately effective category, the effectiveness of understanding which shows 59% results in the moderately effective category and the effectiveness of teaching materials on mathematical critical thinking skills showing 62% results in the moderately effective category. Therefore, the use of mathematics teaching materials on mathematical critical thinking skills is quite good in its delivery and implementation.

Abstract

This research is a classroom action research conducted with 2 cycles. This research was conducted on Merger class students X TKJ and TKRO of SMK Dwi Putra Sindangkerta for the academic year 2022/2023 using a scientific approach. This study aims to determine classroom action research and understanding of mathematical concepts, especially the material equations and inequalities of linear absolute value of one variable using a scientific approach. In this study, the results of students' answers using data analysis techniques with qualitative analysis have four stages: 1). Data collection; 2). Data reduction; 3). Data presentation; 4). Conclusion. The first cycle's lack of student activity was demonstrated by the average score of 62.70 for all students, Student scores increased by 24.58 from the average initial test score of 38.12. In the second cycle test the results have increased the average score of 38.12, student scores climbed by 24.58. It can be concluded that the mastery of the concept of linear absolute value equations and inequalities of one variable in Merger X TKJ and TKRO class students at Dwi Putra Sindangkerta Vocational School has increased.

Abstract

The purpose of this study is to find out: (1) The learning activities of students of class XII IIK MAN Kota Cimahi on average inequality material using the Problem Based learning model. (2) Whether the learning outcomes of students of class XII IIK MAN Kota Cimahi average inequality material using  Problem Based Learning can increase. Research is a class action study, this study is conducted in 2 cycles with each cycle consisting of 2 meetings. Before performing class actions are done ¬pre-test  to students, then carried out cycle I and cycle II activities using the Problem Based Learning model. Based on the results of this study shows an increase in student learning outcomes seen from the completion of student learning outcomes. In cycle I there was an increase of 44% then in cycle II there was an increase of 69% in learning outcomes more than 7. This shows that the improvement of student learning outcomes of class XII IIK MAN Kota Cimahi can be improved through the Problem Based Learning model.

Abstract

Through the use of Realistic Mathematics Education (RME) approach, this activity seeks to improve mathematics learning outcomes. This research uses classroom action research as its methodology. At An-Naja Middle School, this research was conducted. The sample of this study amounted to 15 students, and the implementation took place in November. RPP, LKPD, and description exam questions are research tools used. The written test data processing technique in this study used the percentage. The results showed that 1) by using the RME approach, student learning outcomes have increased as indicated by the increase in student learning success, where the average value of students in the first cycle is 38.80 with a percentage of 6.6% and increased to 89.40 with a percentage value of 100 % in cycle II. The application of the method can be concluded from the research findings. The application of realistic mathematics teaching strategies can improve student learning outcomes.

Abstract

This research is a classroom action research (CAR) with the main objective of improving students' Mathematical Comprehension Ability (KPM) in algebraic form with the help of the application of a scientific approach. This research is motivated by the lack of student KPM in learning mathematics. This CAR is carried out with research stages including (1) Planning (Planning), (2) Action (Acting), (3) Observing (Observing) and (4) Reflecting (Reflecting). This study has a subject, namely 16 students in class VII C SMP Bhakti Mulya Batujajar with data collection techniques through pretest and posttest in the form of 6 questions, teacher observation sheets and student observation sheets. The implementation of this research is for 2 cycles consisting of 4 meetings. Data analysis was carried out quantitatively and qualitatively. So the result of this research is that the student's KPM in the first and second cycles increased by 18.75% where in the first cycle students' learning completeness was 68.75% in the second cycle to 87.5%. So it can be concluded that, KPM in learning mathematics can be improved with the help of the application of a scientific approach.

Abstract

As we know, there are still many students who still have difficulty understanding the set material. This of course affects the learning outcomes. Thereofere, a Problem Based Learning (PBL) learning method is needed into mathematics learning, with the hope that students are more familiar with and understand the concepts given to the set material. The purpose of this research is to improve the learning outcomes of mathematics on set material. This study uses a Class Action Research (CAR) model with 30 students in class VII-D SMPN 1 Margaasih. This research was conducted in three cycles, with each cycle consisting of: 1) Planning, 2) implementation, 3) observation, 4) reflection. The data analysis technique is to see the increase in learning outcomes from the three learning cycles with a limit of 85% reaching the KKM value of 75. The learning outcomes of SMP Negeri 1 Margaasih students who initially be concluded that with the Problem Based Learning (PBL) method students better understand the material and have an effect on increasing learning outcomes.

Abstract

This study aims to examine the scenario and implementation of online learning, the reaction of teachers and students to learning, the difficulties felt by students in completing the problem, as well as the obstacles experienced by teachers when doing online learning material system of linear equations two variables using CTL approach. This study is a qualitative descriptive research. This study was conducted on 20 students of SMP Plus Darul Amanah Ciwidey. The results of the study went as planned, the teacher's reaction when the learning process got a score of 94% which included very good criteria, it can be seen from the results of teacher observation sheets carried out each learning meeting, the student's reaction to learning got an average score of 71% with a very good category. The difficulty experienced by students in working on a system of linear equations of two variables lies in the difficulty of skills, concepts, and principles. The obstacles experienced by teachers when carrying out learning are varied such as students who do not have internet quotas, expensive internet payments, signal constraints, lack of student motivation, and lack of supervision from parents during the learning process.
