Covid-19 Pandemic has changed all sectors, one of which is the system in education. Teachers and students are required to learn from home through online learning, it affects the mathematical resilience of students. This research is motivated by the number of findings of decreased student resilience in learning mathematics. The purpose of this study is to examine: (1) Steps of online learnin…
The purpose of this survey is to examine attainment of student’s mathematical critical thinking skill (MCTS) and mathematical self confidence (MSC) according to its cognitive stage. The survey concerns with 36 eighth grade students’, test of logical thinking (TOLT), an essay MCTS test, and a MSC scale. Analysis data of this survey are computation on percentage and testing existancy of a…
Pada masa pandemi Covid-19 seluruh kegiatan pembelajaran bersifat daring dan mayoritas kegiatan pembelajaran menggunakan handphone. Oleh karena itu, penelitian ini bertujuan untuk menghasilkan Lembar Kerja Siswa (LKS) pada materi Bangun Ruang Sisi Datar (BRSD) dengan menggunakan model matematika Knisley berbantuan Geometryx di masa Covid-19. Pengembangan LKS ini dipandang dapat menjadi satu alt…
Pembelajaran secara daring merupakan salah satu cara mengajar yang efektif saat kondisi pandemi seperti saat ini, namun tentunya pembelajaran harus dikemas dengan baik, salah satunya seperti pada penelitian ini. Penelitian ini bertujuan untuk mengembangkan bahan ajar menggunakan live worksheet berbasis realistic mathematics education (RME) berbantuan geogebra yang validitasnya baik dan juga pra…
This study aimed to develop teaching materials to improve the mathematical understanding of the Pythagorean theorem material by using the development of teaching materials through the GeoGebra-assisted Problem Based Learning (PBL) approach. This study uses the Borg & Gall model's research and Development (RnD) development method with the Borg & Gall model. The researchers collected data through…
Mathematics has an important role to play in life. But the reality in the field shows that many students still have difficulty in understanding math lessons, including geometry. The evidence in the field shows that the results of learning geometry are still low. The difficulty in understanding this geometry material has an impact on other materials related to the geometry material itself. St…
This study aims to determine whether there is a relationship between students' mathematical communication skills in terms of self-efficacy in line gradient material. This is because the achievement that students have is still relatively minimal or low. This study uses a qualitative descriptive research method with samples taken from one of the schools in Cimahi with one class of research subjec…
The purpose of the study was to analyze and determine the effect of the problem based learning model on the mathematical understanding ability of junior high school students on the material of one variable linear inequalities. This research is a classroom action research, which was carried out for 2 cycles. The subjects in this study were students of class VII-I of SMP Negeri 1 Cipatat in the a…
Researchers conducted research that aims to determine the problems faced by students when learning mathematics, which are the factors that cause errors in solving mathematical problems. This error factor must be known so that it is easier to get solution and the parts that need to be emphasized during learning. This research is a qualitative descriptive study to analyze and describe the types o…
This research is a classroom action research. The purpose of this study is to describe the application of the discovery learning model and to determine student learning outcomes after the application of the discovery learning model to mathematical problem solving abilities. The subjects of this research were 12 students of class IX E SMP Bhakti Mulya Batujajar in the academic year 2021/2022. Da…
