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

Classroom Action Research (CAR) aims to determine students' understanding of the Cartesian coordinates material for class VIII through the application of the MURDER model (Mood, Understand, Recall, Digest, Expand, Review). The subjects in the study were 18th graders at SMP Negeri 1 Cipeundeuy. The research was carried out in two cycles. The technique of collecting research data is by using observation techniques and giving description tests. The results of data collection were processed using qualitative data, these results were obtained from the results of students' pretest and posttest scores. These results can be said to be complete if they get a value of 75. From the results of research conducted by researchers, it showed an increase in the completeness of the description test after the pretest and posttest were carried out in each cycle. In the first cycle, which was carried out using the MURDER learning model, students' mastery increased from 16.67% to 61.6%. Cycle II with the MURDER learning model assisted by LKPD reached 83.3%.

Abstract

Pembelajaran matematika yang bernuansa interaktif dan sesuai dengan kompetensi pedagogik perlu diterapkan untuk menciptakan peserta didik agar berprestasi dan memiliki kemampuan matematis yang sistematis, luwes, dan logis. Namun, penalaran matematis siswa masih rendah dan masih adanya paradigma siswa bahwa matematika itu sulit. Untuk mengatasi kesulitan siswa dengan menggunakan bahan ajar ETICA matematik berbasis VBA yang digunakan pada penelitian. Penelitian ini bertujuan untuk menganalisis efektivitas bahan ajar dan melihat perbedaan peningkatan kemampuan penalaran siswa yang mengunakan bahan ajar ETICA matematik dengan siswa yang menggunakan pembelajaran biasa. Metode penelitian yang digunakan ialah quasi eksperimen dengan mengujicobakan pembelajaran dan praktik baru terhadap siswa. Subjek pada penelitian ini yaitu siswa kelas IX SMPN 1 Cisarua, dengan ketentuan kelas IX-H sebagai kelas eksperimen berjumlah 21 siswa dan kelas IX-G sebagai kelas kontrol sebanyak 21 siswa. Instrumen yang digunakan adalah wawancara, dokumentasi, dan tes butir soal bangun ruang sisi lengkung tipe uraian. Prosedur pengolahan data menggunakan SPSS 15.0 dan Microsoft Excel dengan analisis statistika deskriptif dan statistika inferensial. Hasil penelitian menunjukkan bahwa  bahan ajar ETICA matematik efektif, dalam meningkatkan kemampuan penalaran matematis siswa,  Mathematical learning that is interactive and in accordance with pedagogic competencies needs to be applied to create students so that they excel and have mathematical abilities that are systematic, flexible, and logical. However, students' mathematical reasoning is still low and there is still a student paradigm that mathematics is difficult. To overcome students' difficulties by using VBA-based mathematical ETICA teaching materials used in research. This study aims to analyze the effectiveness of teaching materials and see differences in the increase in the reasoning abilities of students who use ETICA mathematics teaching materials and students who use ordinary learning. The research method used is quasi-experimental by testing new learning and practices on students. The subjects in this study were students of class IX SMPN 1 Cisarua, with the provision that class IX-H as the experimental class consisted of 21 students and class IX-G as the control class consisted of 21 students. The instruments used were interviews, documentation, and item tests on the description type of curvature. Data processing procedures using SPSS 15.0 and Microsoft Excel with descriptive statistical analysis and inferential statistics. The results of the study showed that the mathematics ETICA teaching materials were effective in improving students' mathematical reasoning abilities

Abstract

This study focused on analyzing student errors in problem solving questions in terms of Newman's theory on questions in the subject matter of Arithmetic Sequences and Series. The subjects in this study were 10 students of class XI IPA 2 at Al-Mukhtariyah Rajamandala High School using a descriptive qualitative method. For the technical implementation, students were given questions directly in class. Based on the results of the analysis in this study, students' errors in reading error) that is equal to 62%, then an error in understanding the problem (comprehension error) that is getting a result of 60%, then an error in transforming (transformation error) that is equal to 52%, an error in the completion process stage (process skill error) is 26%, and finally an error in writing the final answer (encoding error) that is getting a percentage of 20%. If seen from the mistakes that have been made, students are still low in problem solving.
