This study employed a qualitative descriptive methodology with a phenomenological approach. Principals, instructors, students in Classes I, III, IV, and VI, and students in Classes III, IV, and V served as data sources for both primary and secondary data. This research employs nonparticipant observation employing field survey techniques (field study), interviews (interviews), documentary studies, and literature studies as its methodology. During the Covid-19 epidemic, the results of the study demonstrate that the offline and online learning processes at SDN 5 Namlea are very efficient and effective. The school incorporates offline learning through 1) shift (alternating teaching and learning), 2) television, 3) study groups, and 4) home visits. In the process of online education, teachers utilize two media platforms, namely WhatsApp and YouTube. During the Covid-19 pandemic, SDN 5 Namlea implemented offline and online learning strategies by 1) conducting learning activities (Blended Learning, Offline, Online); 2) using technological facilities such as gadgets, laptops, internet, and wifi; and 3) utilizing application media, namely WhatsApp and YouTube.","PeriodicalId":280543,"journal":{"name":"International Journal of Trends in Mathematics Education Research","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A special theory or method is needed to simplify calculations. Many problems that are too complex, an exact solution is needed to support numerical solution. There are many numerical methods that can be used to solve nonlinear problems, including the Bisection, Secant and Newton methods, also known as the Newton-Raphson method. However, these methods cannot be used for large-scale of nonlinear programming problems; for example the Newton-Raphson method which does not always converge if it takes the wrong initial value. The Newton-Raphson method is widely used to find approximations to the roots of real functions. However, the Newton-Raphson method does not always converge if it takes the wrong initial value. Therefore, it is necessary to develop the Newton-Raphson method without using other methods in order to have a higher convergence. This research is a literature study compiled based on literature references with the initial step of understanding problems that appear from the use of Newton's method, it is base on the problem of divergence or oscillation. Newtonian method was developed without modification of other methods, but took two starting points. Then prove the super-quadratic convergence of the proposed method by extending the Taylor expansion and giving or assuming the error rate. After that, the stability test of the proposed model is carried out and provides an example of the application by solving the root search using Newton's method and the proposed method can be seen as a comparison.","PeriodicalId":280543,"journal":{"name":"International Journal of Trends in Mathematics Education Research","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123876820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical ability in AKM is the ability to solve mathematical problems using various numbers and symbols in the context of numbers, measurements and geometry, data and uncertainty, and algebra that uses cognitive processes of knowing, applying, and reasoning in personal, socio-cultural, and scientific contexts. This research is a type of development research that aims to produce a product in the form of an expanded multiple-choice test instrument to measure the numeracy skills of seventh-grade junior high school students. The development model used is the four-D Model by Thiagarajan which is modified into three stages (define, design, and develop). The scoring technique uses polytomies and involves 70 students as test subjects for the instrument. The results showed that (1) the characteristics of the AKM instrument developed in terms of context and cognitive level were close to the estimated percentage and covered four domains with their respective minimum competencies, (2) item validity values ranged from 0.274 to 0.743, (3) the instrument reliability coefficient is 0.88, (4) the level of difficulty is 8% easy, 80% is moderate and 12% is difficult, (5) the discrepancy index is between 0.43 to 0.78, (6) 92% questions have good distractor effectiveness.","PeriodicalId":280543,"journal":{"name":"International Journal of Trends in Mathematics Education Research","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114926849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Plomp model, which has three steps total—the preparatory stage, the development stage, and the assessment—is used in this particular sort of study, which is called development research. For class VIII of junior high school, LKPD employs a discovery learning methodology with the use of a QR code. The tools employed are validation sheets, observation sheets, questionnaires, interviews, and final exams. The findings demonstrated the validity, applicability, and efficacy of the LKPD for class VIII junior high school students using the discovery learning approach. LKPD practicality was 87%, while LKPD validity was 89%.
