Analisis Kemampuan Pemecahan Masalah Matematika Siswa Kelas VII pada Materi Operasi Bilangan Bulat

Problem solving is a measure or knowledge that needs to be mastered in solving problems related to real life. This ability is very important to build new knowledge as well as develop ideas. Therefore, the purpose of this study is to analyze the ability and describe the weaknesses of grade VII students in solving math problems in integer operating materials at SMP Negeri 1 Waingapu. Descriptive research type with qualitative approach. The instruments used were tests, interviews, questionnaires and documentation. The subjects of the study were the wakasek part of the curriculum, mathematics teachers and 7th grade students. The results found that the average math problem solving ability of students based on Polya steps is 59.86 and is in a fairly good category. This is because students do not write down the information encountered, do not analyze the problem first, do not write down the strategies used in solving the problem, lack of basic ability in doing calculations, difficulty in placing the sign of the calculation operation, not used to re-examine the answers that have been done and not used to write conclusions.Kemampuan pemecahan masalah merupakan tolak ukur atau pengetahuan yang perlu dikuasai oleh siswa dalam memecahkan masalah yang berhubungan dengan kehidupan nyata. Kemampuan ini sangat penting untuk membangun pengetahuan baru serta mengembangkan ide-ide yang dimiliki. Oleh sebab itu, tujuan dari penelitian ini yaitu untuk menganalisis kemampuan serta mendeskripsikan kelemahan siswa kelas VII dalam memecahkan masalah matematika pada materi operasi bilangan bulat di SMP Negeri 1 Waingapu. Jenis penelitian deskriptif dengan pendekatan kualitatif. Instrumen yang digunakan yaitu tes, wawancara, angket dan dokumentasi. Subjek penelitian yaitu wakasek bagian kurikulum, guru matematika dan siswa kelas VII. Hasil penelitian ditemukan bahwa rerata kemampuan pemecahan masalah matematika siswa berdasarkan langkah Polya yaitu 59,86 dan berada pada kategori cukup baik. Hal ini disebabkan siswa tidak menuliskan informasi yang ditemui, tidak menganalisis soal terlebih dahulu, tidak menuliskan strategi yang digunakan dalam menyelesaikan soal, kurangnya kemampuan dasar dalam melakukan perhitungan, kesulitan  dalam menempatkan tanda operasi hitung, tidak terbiasa memeriksa kembali jawaban yang telah dikerjakan dan tidak terbiasa menuliskan kesimpulan

KEMAMPUAN BERPIKIR KRITIS SISWA DALAM MENYELESAIKAN SOAL OPERASI HIMPUNAN

This study aims to describe critical thinking skills, identify factors that affect critical thinking skills and recommend follow-up plans to overcome students' low critical thinking ability to complete class VII set operations problems at Waingapu City Junior High School. This type of research is descriptive research with a qualitative approach. Data collection uses tests, interviews and documentation studies. The subjects in the study were 30 students of class VII junior high school in Waingapu City. The results found that the average critical thinking ability of students was 37.29 and was in the low category. There are several factors that affect students' critical thinking skills, including lack of relearning of the material that has been obtained, mastery of mathematical concepts, learning interests and students' thoroughness in working on problems. The recommendations of actions taken by teachers are reviewing the basic concepts of mathematics, designing learning devices and training students to work on story problems and learning motivation

Pelatihan Penggunaan Google Meet dan Google Classroom bagi Dosen Tidak Tetap Universitas Kristen Wira Wacana Sumba

Universitas Kristen Wira Wacana Sumba is one of the universities that organizes online learning. This happened as a result of the COVID-19 pandemic. This situation requires all lecturers to be able to conduct online learning by utilizing the available facilities, namely Google Classroom and Google Meet, both permanent and adjunct lecturers. Permanent lecturers have used the application since the beginning of the covid-19 pandemic, while adjunct lecturers who held lessons this semester have never used the Google Classroom and Google Meet applications. If this is allowed, then learning will not be held properly. Therefore, this training is carried out in several stages, namely analyzing the needs of non-permanent lecturers, implementing activities, and following up. This training makes the online learning by adjunct lecturers can be carried out properly. Based on the results of the follow-up, the participants proposed further training on the use of Google Classroom, especially in making assignment assessment rubrics and quizzes

Pelatihan Penggunaan Google Classroom dan Google Meet bagi Tenaga Pendidik SMP di Kabupaten Sumba Timur

The implementation of this Community Service activity is motivated by the problems experienced by partners at SMP Kristen Payeti. The teachers in that school have not been able to take advantage of online learning applications such as Google Classroom and Google Meet. Therefore, to overcome the partner's problems, training was carried out by the PkM Team of Program Studi Pendidikan Matematika Universitas Kristen Wira Wacana Sumba, which aims to educate the teachers so that they can increase their knowledge and skills related to the use of the two applications. The training activities were carried out using lectures, demonstrations, and simulations using Google Classroom and Google Meet. While the stages of implementation include the preparation of training modules, preparation of training rooms, and implementation of training. The results of this service activity indicate that there is an increase in the knowledge and skills of teachers as trainees in using the two applications. Thus it can be concluded that the purpose of this service activity has been achieved. The follow-up carried out was to monitor the use of these two applications by teachers in the implementation of online learning

ANALISIS KESALAHAN SISWA DALAM MENYELESAIKAN SOAL OPERASI PECAHAN BENTUK ALJABAR SMP

According to the national examination (UN) scores for Junior High School in East Sumba in 2019, it can be seen that the percentage of student’s math scores based on the comparison of test scores with graduation standards is still very low. In view of the problem, studies are conducted to describe a student’s error, describing the factors that cause students to make mistakes in solving problems, and planning follow-up actions to minimize student errors when operating addition and subtraction of algebraic fraction. This type of research is qualitative approach. The technique of determining the student’s research subject uses the cluster sampling technique with sample 5 students. The technique of collecting data is done by writing tests, interviews and documentary studies. The results showed that according to Newman’s five types of errors, student made 5 types of errors, and the most common mistakes were in encoding error of 1,53%, then processing skill error 2,33%; transformation error 2,5%; comprehension error and reading error 3,1%
