[Bahasa]: Salah satu metode pembelajaran yang cocok digunakan untuk operasi perkalian adalah metode jarimatika. Metode ini diberikan kepada siswa SD di Kefamenanu mengingat berdasarkan data Badan Pusat Statistik (BPS), Kefamenanu telah memiliki empat perguruan tinggi namun masih banyak siswa yang belum memiliki kemampuan berhitung cepat. Kelebihan metode jarimatika adalah tidak memerlukan alat peraga dan hafalan karena perhitungan dilakukan dengan memanfaatkan jari tangan sehingga diharapkan operasi hitung perkalian dapat lebih mudah dipahami, menyenangkan, dan tidak membebani memori otak siswa. Tujuan kegiatan pengabdian ini adalah untuk meningkatkan kemampuan berhitung siswa sekolah dasar. Kegiatan ini dilaksanakan di SDN Neonbat Kefamenanu, Nusa Tenggara Timur (NTT) dengan subyek pengabdian seluruh siswa kelas V yang berjumlah 60 orang. Pengabdian dilaksanakan dalam bentuk workshop yang dibagi menjadi 2 hari. Pelaksanaan hari pertama fokus pada review kemampuan dasar siswa yang meliputi perkalian 1-5 dan dilanjutkan dengan perkenalan teknik berhitung cepat dengan jarimatika untuk perkalian 6-10 dan 11-15. Pengabdian dilanjutkan pada hari kedua yaitu review materi pada hari sebelumnya dan penyampaian teknik berhitung cepat untuk kelompok 16-20 yang diakhiri dengan pemberian latihan. Kegiatan pengabdian tidak hanya berhenti pada workshop tetapi dilanjutkan dengan pendampingan terhadap siswa yang dipilih sebanyak 20 orang. Kegiatan pendampingan ini memberikan dampak positif terhadap hasil belajar yang diperoleh siswa. Hal ini dapat dilihat dari peningkatan nilai rata-rata pada pre-testsebesar 55,84 dan pada post test sebesar 75. Kata Kunci: berhitung cepat; metode jarimatika; perkalian; sekolah dasar [English]: One of the appropriate methods to learn multiplication is Jarimatika. It was given to elementary school students in Kefamenanu which, based on data from statistical central agency (BPS), has four colleges but there are still many students who do not have rapid counting skills. The advantage of this method is not requiring learning tools and memorization because calculations are done by utilizing the fingers so that the expected counting operation of multiplication can be more easily understood, enjoyable, and does not overload students’ memory. The purpose of this community service program was to improve the counting skills of elementary school students. It was held at SDN Neonbat Kefamenanu, East Nusa Tenggara (NTT) involving 60 5th-grade students. The program was carried out in two-day workshop. The first day focused on the review of students ' basic ability which includes multiplication 1-5 and continued with the introduction of quick counting techniques with Jarimatika for multiplication 6-10 and 11-15. The second day was to review the previous day and introduce the rapid counting technique for multiplication 16-20. This program did not only end with the workshop but also continued with the assistance of 20 selected students. This assistance provided a positive impact on the results students get which can be seen from the increasing average score: 55,84 in the pre-test then increased to 75 in the post-test.

The purpose of this study was to explore how examples used in teaching may influence elementary school students' conceptions of evaporation and boiling. To this end, the examples traditionally used to explain evaporation and boiling in Korean 4th grade science textbooks were analyzed. The functions of these published examples were explanation (empirical recognition, identification, and evidence) and reinforcement (applications). However, few reinforcement functions (such as comparison and supposition) or clarification functions (such as extension and contrast) were employed. The evaporation and boiling conceptions of 41 students in the 4th grade, 55 students in the 5th grade, and 28 students in the 6th grade were surveyed. Many students thought of evaporation phenomena under heating conditions as boiling, and the same phenomena without an obvious source of heating as evaporation. This meant that the presence of heating affected the students' conceptions of evaporation and boiling. In this study, the students were presented with clarifying functional examples that were not included in the textbooks. After exposure to these examples, many students revised their misconceptions and adopted scientific conceptions. Previous studies have argued that students must be able to reason from a microscopic point of view to understand evaporation and boiling phenomena; however, the tested students were able to classify the two different phenomena after experiencing appropriate functional examples.

Natural Science is an elementary school subject that requires students to organize ideas and concepts about the natural world gained from experiences through a series of scientific processes such as investigating, composing, and presenting ideas.  The high complexity causes many cases of learning difficulties. This study aims to diagnose the learning difficulties that occur on 5th-grade elementary school students. The research was conducted in Muhammadiyah Pakem Elementary School, Sleman, Yogyakarta Special Regency.  The subjects were 29 of 5th-grade elementary students. Data collection techniques were interviews, tests, and documentation. Data analysis techniques were descriptive statistic as a quantitative analysis and interactive model as a qualitative analysis. The learning difficulties were diagnosed by describing the students who were identified having learning difficulties; localizing the difficulties; and determining the factors that cause learning difficulties. The results showed that the difficulties experienced by students were in basic competence 1.1-1.5 (human blood circulation organs). The average percentage of students’ learning difficulties in Basic Competence 1.1 was 48%; Basic Competence 1.2 was 51.1%; Basic Competence 1.3 was 57.6%; Basic Competence. 1.4 is 64.7%; and Basic Competence 1.5 is 53.7%. The highest percentage of learning difficulties was in Basic Competence 1.4 (identifying human circulatory organs). It was caused by the students’ low attention and motivation to learn natural science, the imprecise teaching methods, the parents’ attention, and the negative influence of mass media.
