Kegiatan pengabdian ini bertujuan untuk mengatasi learning loss yang diakibatkan oleh pandemi Covid-19 yang terjadi di Indonesia. Selama masa pandemi, siswa-siswa belajar dengan sistem pembelajaran daring. Resiko learning loss terjadi selama pembelajaran daring karena kurangnya pengawasan dari orang- tua dan tidak ada interaksi dengan teman sejawat yang dapat mengurangi motivasi siswa dalam belajar. Oleh karena itu, program English Intensive Course dibuat untuk mendampingi jemaat GMIT Sion Sasi usia sekolah di Kefamenanu, NTT, untuk memberikan pengetahuan dan latihan lebih dalam penggunaaan Bahasa Inggris sehari-hari yang selama ini tidak bisa dipraktekkan di pembelajaran daring. Metode yang dilaksanakan adalah pelatihan Bahasa Inggris dalam kegiatan sehari-hari seperti supermarket shopping, giving directions, describing cities, dan describing people. Hasil dari kegiatan pengabdian ini menunjukkan adanya peningkatan kemampuan siswa dalam penggunaan Bahasa Inggris dari hasil rata-rata pre-test 5.05 naik menjadi 6.5 pada hasil rata-rata post-test. Siswa juga memberikan kesan positif dan merasakan manfaat dari kegiatan ini, tidak hanya dari segi peningkatan nilai namun juga dalam hal motivasi belajar. Siswa dapat melakukan interaksi dan praktek percakapan Bahasa Inggris dengan rekan sejawat sehingga siswa bisa tampil percaya diri dan dapat menyelesaikan latihan dengan baik.

Literacy Numeracy is currently one of the topics in learning mathematics. A person is said to have Numerical Literacy Ability to count, distinguish and process various data symbols, and perform basic mathematical operations to fix the problem. However, the problem that is always faced by students today is the lack of understanding of the basic concepts of mathematics, one of which is integer arithmetic operations, so it won't be easy to understand more abstract mathematical concepts. The low numeracy literacy ability is due to the learning process not applying the suitable model or media. Therefore, it is necessary to have appropriate learning media so that students understand concepts well and can improve Numerical Literacy skills. One of the proper media or teaching aids for learning integer arithmetic operations is Koin Muatan, made with paper as a base material that symbolizes positive and negative charges. The type of research used was experimental research, a one-group pretest-posttest design pre-experimental design on 21 SD GMIT 4 Kefamenanu students. Data collection techniques were observation, tests and documentation. At the same time, the data analysis technique used is descriptive statistical analysis, inferential analysis and N-Gain analysis. The t-test results are used to test the average value before and after being given treatment and whether there is a significant effect. Based on the results of the tests performed, the average pretest and posttest values were 43.51 and 70.79. An N-Gain test was carried out to determine the large increase in numeracy literacy skills so that an N-Gain value of 0.45 was included in the moderate category. This result proves an increase in numeracy literacy skills after students are given the learning treatment using the Koin Muatan teaching aids at SD GMIT 4 Kefamenanu.

Research design is a didactic-oriented research method, predicting student responses before learning and paying attention to student conditions during and at the end of learning. However, comprehensive studies have yet to show trends in design research worldwide. This study investigates design research trends through bibliometric study of widespread and open-access databases, namely the Google Scholar and Scopus databases, from 2012 to 2022. We reviewed 997 documents from Google Scholar and 94 from the Scopus database on Harzing's Publish or Perish (PoP) 8.7.4245.8399 version on March 10, 2023. The descriptive analysis approach was employed to analyze the data; data from PoP was processed using Microsoft Excel and VoSViewer. The vizualitation show that there are four significant clusters related to design research are the learning process, local instructional theory, realistic mathematics education, and didactical design research. The findings can help scholars identify design research trends and guide future investigations because in the last three years (2020-2022), there aren’t recent research related to design research. Future research should compare Google Scholar, Scopus, other sources to investigate more years, and deepen meta-analysis on design research.

Literacy Numeracy skills (LNS) are fundamental for facing global challenges in the 21st century. LNS can help people achieve their goals. However, there has not been a thorough study on literacy and numeracy research. To improve the quality of literacy and numeracy research, researchers must study much literature for further analysis. This research aims to analyze students' literacy and numeracy skills in facing 21st-century challenges. The research method used is the Systematic Literature Review to read 27 documents by searching for the keywords "literacy", "numeracy", and “Literacy and Numeracy”. This type of research is library research with the stages of determining research questions, searching literature, selecting articles, reading full papers, making abstractions, and conducting analysis. The data analysis technique used is content analysis. The study results show that the dominant research methodology used is quantitative; the instruments often used are tests and assessments. The chief field is mathematics; the overall educational level is junior high school and early childhood education. Some motivational results research related to literacy and numeracy skills includes digital competencies, learning videos, and games, effectively improving literacy and numeracy skills. Furthermore, not all learners have strong reading and numeracy abilities. A strong recommendation for further research is to develop learning media based on local wisdom using the Android platform. In addition, researchers must embed emergent literacy in the design and case study of didactically and pedagogically oriented research.

Mathematical reasoning is an essential ability that must be possessed by students when studying at university or in real life. Mathematical reasoning ability is one of the material sub-topics tested in the 2019 computer based written exam. In solving mathematical reasoning content questions, students often make mistakes in answering questions. The mistakes made by students occur due to various factors. Therefore, this research aimed to describe student errors and the factors that caused student errors in solving computer based written exam questions on the topic of mathematical reasoning according to Newman's theory. This research used a mixed method with 28 class XII students as the research subjects. The research instruments were written tests and interviews. The factors that caused reading errors were because students could not interpret the questions properly, misunderstandings occurred because students could not determine the necessary information in the problem, transformation errors occurred because students could not determine the correct method to solve the problem, process skill errors occurred because students were less thorough in solving questions and because of previous mistakes, mistakes in writing the final answer occurred because students were not used to writing conclusions and also because they were in a hurry.

This study aims to improve students' numeracy literacy skills on integer operation material using Manik-Manik media. The method used is Classroom Action Research (CAR). Research is carried out in two cycles, and each process consists of three meetings, with stages: planning/preparation of actions, implementation of activities, observation, and reflection. Data collection techniques using observation techniques (teachers and students), learning outcomes tests, and documentation. Based on the results of the research on 25 students, it is known that there was increasing in student learning outcomes from before the action, Cycle I and Cycle II. This is evidenced by the post-test value that was carried out in cycle I, which showed an average value of 59.4, and then the increase in cycle II with an average value of 90.8. The data analysis techniques used are data analysis of observations of teachers and students and analysis of test result data in the form of classical completeness. Based on the research on integer operation material, it was concluded that learning by using Manik-Manik can improve students' mathematics learning outcomes. Thus, using Manik-Manik media can improve students' numeracy literacy skills on integer operation materials. Keywords: Integer, Manik-Manik Media, Numeration Literacy, CAR.
