Abstract

During the Covid-19 pandemic, there was a change in the education system, namely regular or face-to-face learning suddenly changed to learning from home (BDR). One of the difficulties is the change in the direct learning climate to online learning, which is done individually. This difficulty resulted in learning loss for students. Learning loss has a long-term negative impact, namely reduced student academic achievement and cognitive skills. Therefore, it is necessary to choose learning media to minimize learning loss due to BDR during the Covid-19 pandemic. One learning media that is suitable for the conditions of the learning community in Kefamenanu City is the Mathematics learning media made from Waste (MPMBS), namely positive and negative charges. This study aims to reduce learning loss for students in the learning community in the city of Kefamenanu. The type of research is an experimental, pre-Experimental Design, namely a One-Group Pretest-Posttest with 11 students in the Sunday school community at one of the GMIT Churches in Kefamenanu. Data collection methods are tests, questionnaires and documentation. The data analysis techniques are descriptive statistical analysis, N-Gain analysis and inferential analysis. The results showed that the average value of the pretest was 33, and the average value of the posttest was 57.17. There was an increase after the students were given the learning treatment using MPMBS with a charge of 27.57 and an average N-gain of 0.64, including the medium category. Based on the results of this study, it can be concluded that the use of waste-based MPMBS in learning integer operations can improve learning achievement while reducing learning loss in the community of Sunday school children in Kefemenanu. The next plan that will be done is to analyze the level of motivation of respondents to the use of MPMBS

Abstract

This study investigates lesson study research trends through bibliometric analysis on widely distributed Google Scholar (GS) and Scopus databases. We reviewed 997 papers from GS and 200 documents from the Scopus database searched using Harzing's Publish on May 6 2023. A descriptive study approach was used to investigate the data. The result of this study is that the number of lesson study documents has increased over the last decade (2012-2022). The most productive author based on GS  is R Huang from the United States, and the full author based on Scopus is E. Saito from Australia. While the prominent authors based on the highest citations are Fernandez Yoshida, based on GS, and Dudley, with the highest citations based on Scopus. The “International Journal for Lesson and Learning Studies” in the last decade is the most source of lesson study documents. Based on VosViewer visualization, Rosa is the author who has the most co-authorship papers and total link strength. The VosViewer displays four clusters related to lesson study: community, context, observation, and participation. Our strong recommendations regarding this study are lesson study research related to literacy, numeracy, and mathematical abilities. The results can assist relevant researchers in understanding trends in lesson study research and recommend guidelines for other studies.

Abstract

Kegiatan ini didasari learning loss pada saat Covid-19 yang berdampak munculnya murid slow learner akibat adanya kebijakan belajar dari rumah. Tujuan kegiatan ini adalah untuk menguji tingkat efektivitas “Puzzle Rumah Perkalian” dalam menunjang konsep matematika dasar murid slow leraner di Kawasan Perbatasan Darat Indonesia dengan Republik Demokratik Timor Leste. Metode yang digunakan adalah metode kuantitatif dengan jenis eksperimen, yaitu One-Group Pretest-Posttest. Tahapan pelaksanaan penelitian ini dimulai dari perencanaan, pelaksanaan pre test, eksperimen dan postest. Jumlah murid yang terlibat adalah 18 orang siswa sekolah dasar kelas 4. Metode pengumpulan informasi merupakan tes, serta dokumentasi. Metode analisa data yang dipakai merupakan analisa statistik deskriptif, analisa N- Gain serta analisa inferensial. Hasil riset membuktikan kalau nilai rerata pretest merupakan 40,51 serta nilai rerata post test merupakan 66,29. Nyata kalau terjadi kenaikan sehabis peserta didik dikasihkan perlakuan Pembelajaran matematika memakai“ Puzzle Rumah Perkalian” sebesar 25,78 serta rerata N-gain ialah 0,43 termasuk kategori sedang. Bersumber pada hasil studi ini, bisa disimpulkan kalau aplikasi “Puzzle Rumah Perkalian” pada pembelajaran matematika materi operasi bilangan bulat khususnya pada operasi perkalian bisa mendukung matematika dasar anak didik slow learner di Area Perbatasan. Konsep berikutnya yang hendak digarap merupakan meningkatkan alat pembelajaran matematika yang sesuai buat anak didik slow learner di Area Perbatasan.

Abstract

This service is based on changes in the mechanism and substance of the implementation of National Selection for Student Admissions (SNPMB). This transition is something new for prospective students and if prospective students do not understand it, it will 0certainly have a bad impact on the readiness of prospective students in participating in the implementation of UTBK-SNBT. The procedure for implementing the service is a sharing session on the implementation of SNPMB 2023, introduction and discussion of the 2023 UTBK-SNBT model questions, as well as an initial ability test on the representation of the 2023 UTBK-SNBT question model based on the latest UTBK-SNBT sub-matter. Then the socialization participants will be given a test to measure their knowledge of the SNPMB 2023 mechanism after the provision of SNPMB 2023 material. The results of this service activity are that more than 90% of prospective university students at SMA Negeri 1 Kefamenanu have understood the mechanism for implementing SNPMB 2023 after participating in the sharing session, based on the ability test, prospective university students do not fully understand the 2023 UTBK-SNBT model questions, and based on the results of the questionnaire, more than 90% of sharing session participants gave a good response to this activity. The results of this activity are important as a measure of understanding of the SNPMB 2023 mechanism and provide an overview of the initial ability of prospective students to answer UTBK 2023 model questions so that follow-up can be known in accordance with these abilities.
