PERAN BAHASA DALAM KOMUNIKASI PEMBELAJARAN MATEMATIKA SECARA ONLINE PADA MASA PANDEMI COVID-19
Full text linkSchools are closed in Indonesia cause COVID-19 Pandemic has been carried out until two months, not only in Indonesia in many countries also in closing temporary schools to control the prevention of COVID-19. Teaching and online learning are new experiences felt by teachers and students, with many consequences. This paper discusses the role of language in communication in learning mathematics. In the COVID-19 Pandemic, mathematical communication skills with the right language are needed in conveying learning, both in-class learning, text in books or assignments, and writing the sentence structure online on the screen of a smartphone or laptop. The goals of this article to know the role language use of teachers when communicating with students for learning in the COVID-19 Pandemic. This research uses a qualitative method. Data was collected through an online questionnaire, observation, and interview. The Goals of this study include that the role of language in online communication mathematics learning is very important to student learning outcomes. Students become more understanding when the teacher explains in the right language. Because learning in the COVID-19 Pandemic through online learning at home, students understand better if the teacher not only provides an explanation in writing on the screen but also the teacher provides a video explanation of the material, which makes it easier than bef6re for students to understanding the material.Keywords: covid-19; e-learning; language; mathematical communication DOI: http://dx.doi.org/10.23960/mtk/v8i2.pp153-16
ANALISIS KESULITAN SISWA DALAM MENGERJAKAN SOAL CERITA ARITMATIKA SOSIAL DITINJAU BERDASARKAN GENDER
No full textIn our daily lives, Social Arithmetic can be applied easily, but in reality, in the school environment, there are still many students at the junior high school level who are not familiar with Arithmetics. This research wants to determine and analyze the level of difficulty of junior high school students in solving non-routine problems, especially in social arithmetic material In terms of gender. This research is a qualitative descriptive study. This study aims to describe the analysis of student difficulties in arithmetic material on Social Arithmetic without any prior treatment. This research was conducted at one of the junior high schools in Soreang. The subjects of this study the sample in this study was taken randomly, were 8 junior high school students, 4 female students, and 4 male students. Based on the research result, the average score for male students and female students have almost the same ability ie 56 and 53. The average score for arithmetics Material of both male and female students was under the KKM value of 70, which means that both male and female students have not been able to understand and work on social arithmetic story problems properly.Keywords: arithmetic material; gender; student difficulties DOI: http://dx.doi.org/10.23960/mtk/v8i2.pp289-298 Alternative Link -> PD
