Likewise, education in this global era has transitioned to 21-century skills, one of the 21-century skills that students must be possessed, namely mathematical communication ability. Mathematical communication ability is influenced by several factors, such as students' psychological aspects. One of those psychological aspects is mathematical resilience. This study aims to describe students' mathematical communication ability based on mathematical resilience in a Covid-19 pandemic due to pandemic. Based on the study objectives, this study used descriptive qualitative research. Data collection techniques used test of mathematical communication ability, questionnaire of mathematical resilience, and interview. The results showed that the students’ mathematical communication ability was quite good, based on students' mathematical resilience. Still, there were some difficulties that students exper...

Students’ mathematical reasoning, however, is one of the problems occurs in teaching and learning process, where many teachers and lecturers encounter with. Their ability in understanding and analyzing mathematical conceptsusing deductive methodsand drawing a conclusion for constructing valid argumentsare still poor. This research was quasi experiment in nature, with pretest-posttest control group design. Inquiry method was implemented with the use of Algebrator for enhancing students’ mathematical reasoning. The subject in this research was 80 students from 8 classes in one of junior high schools, in Bandung, West Java, selected by applying purposive sampling technique. Th...

This research was conducted to measure the increase in visuospatial reasoning through a hybrid learning model. The non-equivalent pretest and posttest control group design is an experimental design chosen in this study. The subjects of this study were 52 students majoring in mathematics education at one of the private universities in Medan that took the geometry of transformation. All research subjects were divided into three groups: high, moderate, and low based on prior knowledge. In the experimental class, the lecture process is carried out by applying a hybrid learning model with a composition of 70% online learning. Based on data analysis, it was found that visuospatial reasoning improved better in students in the moderate prior knowledge group but did not increas...

Mathematics is one field of science that helped determine and support the progress of science and technology. In studying mathematics, there are still many students both male and female who view mathematics as a boring subject. Based on that, the gender aspect in the learning of mathematics became the attention of educators. Gender differences not only result in different abilities in mathematics, but also how to acquire mathematical knowledge. This research is a qualitative descriptive research which aims to describe students' self-esteem mathematics based on gender and its relationship with mathematics achievement. A total of 72 female students and 68 male students became respondents in this study. The results showed that male students had higher levels of mathematical self-esteem compared to female students and mathematic...

In fact, in general, students’ mathematical communication skill is still low. Metacognitive learning encourages students to reflect on their learning process; individual reflection or interaction with teacher and classmates provides opportunities for students to communicate and explain their thoughts. This research intends to study the application of metacognitive learning and its roles in students' mathematical communication ability. An experiment with pretest-posttest control group design was conducted on the 70 students of 10 th grade of a senior high school at Sumedang, West Java, during the first semester. The students were divided into three categories of mathematical prior knowledge (MPK): high, middle, and low achiever. The instruments used were a mathematical communication test and a set of attitude questionnaires on metacogniti...

Subjek penelitian ini adalah siswa kelas 7 dari dua SMP dengan kategori sedang yang dipilih secara acak dengan teknik purposive sampling dari seluruh SMP di Bekasi. Penelitian ini adalah penelitian eksperimen dengan desain kelompok kontrol pretes-postes. Pada kelas eksperimen dilaksanakan pembelajaran dengan pendekatan matematika realistis dan di kelompok kontrol dilaksanakan pembelajaran konvensional. Instrumen penelitian ini adalah (1) tes kemampuan pemecahan masalah matematis; (2) lembar observasi; (3) angket respon siswa; dan (4) pedoman waawancara. Analisis data dengan uji-t dan ANOVA. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah matematis siswa yang mengikuti pembelajaran dengan pendekatan matematika realistis lebih baik daripada siswa yang mengikuti pembelajaran konvensional s...

There have been many research experts who focus on research about teachers attitude toward mathematics in general, but they rarely sees how the teachers attitude toward mathematical problems solving and its learning process. This study aims to answer both that questions. The research type is qualitative with survey method. Three mathematics teachers from three different schools were selected as research subjects. Teaching videos of each teacher, questionnaires, and interviews with open questions were used as instruments to see the attitude. Each teacher was given a questionnaire on teachers attitude toward mathematical problem solving and its learning process, after which the teachers was also interviewed. Based on the research process, it can be concluded there are three categories of teacher attitude level toward mathematical problem so...

This research used experimental method with pretest-posttest control group design. Population of the research is Junior High School students in Serang City, Banten Province, Indonesia. The sample is eighth grade students from two school levels classified as high and medium levels. Two classes are randomly selected from each school, one class as the experimental group who received ICM and the other class as a control group who received CL. The instrument used consists of MPSA test and observation sheets. The results of data analysis using t-test and two-way ANOVA concluded that: (1) the enhancement and achievement of students' MPSA who received ICM are better than those of students who received CL; (2) school level factors has significantly affect toward enhancement of students' MPSA, but does not has significantly affect toward achievement of students' MPSA; and (3) there are no interaction between learning model and school levels toward achievement and enhancement of students' MPSA.
