<![CDATA[Pembentukan karakter seseorang tidak dapat dilakukan dengan mudah, hal tersebut memerlukan proses yang tidak sebentar. Sedangkan pada tahun 2020 sedang maraknya kasus COVID-19 tersebar, sehingga membuat pembelajaran harus dilakukan secara daring. Tentunya hal ini dapat menjadi peluang terhambatnya pembentukan karakter siswa, terlebih pada siswa Sekolah Dasar. Banyak orangtua yang mengeluhkan tentang anaknya yang hanya mendapatkan pembelajaran secara akademik saja, sedangkan orangtua terkadang tidak bisa selalu mendampinginya untuk menyelesaikan tugas-tugasnya serta dalam proses pembentukan karakter siswa SD ini masih ada kendala. Oleh karena itu, tujuan dari pengabdian ini adalah untuk membantu orangtua membentuk karakter anaknya yang masih di Sekolah Dasar. Pengabdian ini merupakan penyuluhan yang diadakan di sekolah dan nantinya akan disampaikan kemudian pada orangtua. Berdasarkan hasil interview, dapat disimpulkan bahwa orangtua siswa SD tersebut merasa terbantu dan anak-anak mereka jadi lebih terarah dalam pembentukan karakternya.Kata kunci: COVID-19, Pembentukan Karakter, Orangtua Siswa]]>

<![CDATA[The purpose of this study is to develop mathematics differentiation learning worksheets based on learning style and to know the impact for mathematics understanding ability in 4th grade. The method we used was R&D including 10 steps. The instruments were a validation test, questionnaire for teachers and students, and an understanding concept test. Validation and questionnaire data analyzed by descriptive quantitative. Although, mathematics understanding ability data analyzed by difference test and N-Gain test. The results of this study show that the differentiation learning worksheets fit with the criteria. Eligibility validation from experts gets an average of 91%. Practically based on teachers and students’ responses get an average 86%. It means that the learning materials are very valid. The learning materials in experiment class can increase the understanding concept with N-Gain 0,74. We can conclude that with mathematics differentiation learning worksheets can increase mathematics understanding ability. Penelitian ini bertujuan untuk mengembangkan LKPD Matematika Berdiferensiasi Gaya Belajar dan mengetahui pengaruhnya terhadap kemampuan pemahaman matematis siswa di kelas IV SD. Metode yang digunakan adalah penelitian dan pengembangan (RnD) yang terdiri atas 10 langkah. Instrumen pengumpul data meliputi lembar validasi, angket respon guru dan siswa, dan tes pemahaman konsep. Data validasi dan kepraktisan dianalisis secara kuantitatif deskriptif, sedangkan data kemampuan pemahaman matematis dianalisis dengan uji beda dan n-gain. Hasil penelitian menunjukkan bahwa LKPD berdiferensiasi yang dikembangkan memenuhi kriteria kelayakan, kepraktisan, dan keefektifan. Validasi kelayakan oleh ahli memperoleh rata-rata skor 91% (sangat layak). Kepraktisan mengacu pada respon guru dan siswa memperoleh rata-rata skor 86% (sangat baik). LKPD berdiferensiasi di kelas eksperimen mampu meningkatkan kemampuan pemahaman matematis secara efektif dibanding kelas kontrol dengan n-gain 0,74. Berdasarkan hasil tersebut, dapat disimpulkan bahwa peningkatan kemampuan pemahaman matematis siswa sesuai gaya belajarnya dapat dipengaruhi oleh LKPD berdiferensiasi.]]>

<![CDATA[This research is a classroom action research that aims to determine the improvement of students' mathematics learning outcomes after using a scientific approach to online learning. The research was carried out at SMP Negeri 8 Cimahi with the subjects of class IX students totaling 35 people. Collecting data in the form of student test results with a discussion of quadratic equations. This research was conducted in 2 cycles. Each cycle was carried out in 2 meetings. In the first cycle, the learning was less than optimal in applying the scientific approach and the students' motivation to learn mathematics was less. In the second cycle, the deficiencies that occurred in the first cycle were corrected. In cycle II, many students were able to solve the questions given, actively asked if there was something they did not understand and many students were able to participate in online learning using a scientific approach. The results of this study indicate that the scientific approach to online learning can be applied and an increase in each cycle has a good impact on grade IX students at SMP Negeri 8 Cimahi.]]>

<![CDATA[Fraction division is one of the most difficult subjects in elementary school. Not only elementary students but many prospective teachers don’t understand the fraction division concept yet—most of them using a keep-change-flip algorithm to solve fraction division problems. A study using rectangle representation was conducted by us to prospective teachers. This study aims to see whether this rectangle representation will make prospective teachers understand or not. To do so, we made a mixed-method study with 80 prospective teachers as participants. The results show that 53,75% of prospective teachers use the keep-change-flip algorithm without understanding the concept of fraction division, and just 15% of prospective teachers understand fraction division. We assume that most prospective teachers still can’t imagine how fraction division works in a real-life context. They remember what they used to do to finish the fraction division problem that their teacher has introduced in primary school. Based on the results, we conclude that the study with rectangle representation still needs an improvement, whether the teacher’s explanation or the rectangle media.]]>

<![CDATA[Understanding mathematical concepts in multiplication material are indispensable for solving mathematical problems as well as a prerequisite for the next higher material. Based on several studies the lack of students understanding the multiplication concepts is due to internal factors such as the lack of student motivation and external factors such as the lack of innovative learning media used by teachers. Therefore, the approach using ICT (Information and Collaboration Technologies) is expected to be impactful and the development of today's education. This study aims to see the impact of hybrid learning assisted by Google Site and QR Code model on understanding the concept ability of multiplication. This study used quantitative methods with one group pretest-posttest design. The population in this study were 3rd-grade elementary school students with a sampling technique using purposive sampling of as many as 34 students. From this research, it is known that the use of hybrid learning assisted by Google Site and QR Code model impacts understanding concept ability of multiplication which is characterized by an increase in the achievement of results by 0.5 or with moderate interpretation, as well as students' understanding of the multiplication concept and the causes of students' difficulties in understanding the multiplication concept. Based on the results of the study, it can be concluded that the impact of using a hybrid learning assisted by Google Site and QR Code model is an increasing understanding concept ability of multiplication. In the use of hybrid learning assisted by Google Sites and QR Code model, students found difficulties in understanding the concept ability of multiplication. This is shown by students not being able to distinguish multiplier numbers and multiplied numbers, difficulty in interpreting the language of the problem, and still lacking numeracy literacy.]]>
