Jurnal Cermatika means pedagogy or the science of learning, so Jurnal Cermatika is defined as mathematics learning. The presence of mathematics journals is expected to increase the publications in the field of mathematics learning in order to discuss mathematics issues such as students’ perception of mathematics as a difficult subject. Jurnal Cermatika is a periodical academic journal that is published by the Fakultas Keguruan Dan Ilmu Pendidikan, Universitas Graha Nusantara. This Journal is published twice a year (April and October).

Abstract

This study aims: (1) To find out the improvement of students' mathematical problem solving by applying the Discovery Learning learning model to the subject of social arithmetic in class VII SMP Negeri 4 Muara Batang Gadis in the 2021/2022 academic year, (2) To determine the level of achievement of problem solving abilities. students' mathematics by applying the Discovery Learning learning model to the subject of social arithmetic in class VII SMP Negeri 4 Muara Batang Gadis for the 2021/2022 academic year, (3) To find out the management of learning carried out by the teacher by applying the Discovery Learning learning model based on problem solving on the subject of arithmetic Social studies in class VII SMP Negeri 4 Muara Batang Gadis teaching 2021/2022 This type of research is classroom action research. The level of problem solving ability in the first cycle is moderate with a class average score of 70.083 with 26 students (72.22%) Implementation of actions in cycle II, high The problem solving ability of students is high with a class average score of 80.47 with 35 students or 80.083% of all students. Thus it can be said that the class has been completed in learning, there are 80% of students who have a moderate level of problem solving ability.

Abstract

Indonesia experienced the Covid-19 pandemic, precisely at the beginning of 2020. This pandemic had an impact on various sectors, one of which was the education sector. Students and college students still have to follow the policies of the government to implement Distance Learning (PJJ). Although it has been supported by various technologies during the PJJ, there are still gaps that cause learning to be less effective. One of the things that is feared is that if the PJJ lasts for a long time, it will result in learning loss or reduced motivation, knowledge and skills academically. Online learning is learning that uses the internet network supported by learning applications.

Abstract

This The low ability of students' mathematical problem solving affects the success of a learning process. Learning model as a tool to achieve a goal. The better a learning model, the better the achievement. So one of the most important teacher tasks, before carrying out their duties is to know and apply the learning model, the model used in this study is the Number Head Together (NHT) cooperative learning model.This research is a classroom action research (CAR) by taking the research subjects of Class VIII-1 students of SMP Negeri 4 Muara Batang Gadis for the academic year 2021-2022. consisting of 22 students. The objects taken in the research are students' problem solving abilities, student learning activities in the implementation of classroom learning, teacher activities that specialize in the Number Head Together (NHT) type cooperative learning model to improve students' mathematical problem solving on the subject of Two Variable Linear Equation Systems ( SPLDV). The results of this study show that the problem-solving ability of students using the Number Head Together (NHT) type of cooperative learning model for Class VIII-1 students of SMP Negeri 4 Muara Batang Gadis in the 2021-2022 academic year has increased, it can be seen from the students' mathematical problem solving ability in the first cycle of 45 ,45% who completed the second cycle and 81.82% of students who completed the 22 students who took the study test. Based on the research data through the student observers, the percentage was 68.75% in the first cycle and 90% in the second cycle. Based on the research data through teacher observers, the percentage was 3.45 in the first cycle and 3.94 in the second cycle. So, it can be concluded that each cycle has increased and is included in the "very good" category and has met the research achievement criteria, so this research stops in cycle II.Based on these results, the application of the Number Head Together (NHT) learning model can improve students' mathematical problem solving skills on the subject of a two-variable linear equation system in class VIII-1 of SMP Negeri 4 Muara Batang Gadis in the 2021-2022 academic year.

Abstract

The active learning quiz team model is one type of active learning that serves to liven up the atmosphere, increase their sense of responsibility for what they learn. The reason for using the active learning quiz team model is because this strategy is considered to make learning fun and students can actively participate in the learning process. At SMPN 2 Batangtoru Kab. South Tapanuli teachers have not used models, media or methods so that students' interest and activity have not been maximized. This study aims to explain: (1) how the effect of using the active learning quiz team model on the learning interest of class VIII students of SMPN 2 Batangtoru, Kab. South Tapanuli (2) how is the effect of using the quiz team model on the learning interest of class VIII students of SMPN 2 Batangtoru Kab. South Tapanuli and (3) how is the description of the activeness of class VIII students of SMPN 2 Batangtoru Kab. South Tapanuli. This type of research is quantitative research. The research design used is experimental research. In this study the population was all fourth grade students at SMPN 2 Batangtoru Kab. South Tapanuli with a total of 46 students with 23 students for the experimental class and 23 students as the control class.Sampling techniques and population samples. The data collection instruments used tests and questionnaires. The data analysis technique in this study used the T-test. Based on the calculated data, it showed that the average student interest in learning had a t-count value of 2.831 while t-table was 1.684, 0.05 and the average learning outcomes students have a t count value of 6.258 while t table 1.697, 0.05 the above variable shows t count > t table, meaning that Ho is rejected and Ha is accepted, so there is an effect of the quiz team strategy on interest in learning in mathematics learning for class VIII students

Abstract

This study aims to determine whether there is an effect of Blended Learning on the motivation to learn mathematics in class XII TBSM SMK Negeri 1 Angkola Timur. This type of research is an experiment by giving treatment to the research sample group and then given a post-test, as a data collection tool the instrument is a student's mathematics learning motivation questionnaire. The sample in this study consisted of 2 classes of 30 students in class XI TBSM-1 as the experimental class and class XI TBSM-2 as the control class. The results of the questionnaire on students' motivation to learn mathematics obtained an average score of students on the subject of relations and functions of 83.53 and a standard deviation of 10.644 in the experimental class or those given treatment. While in the control class obtained an average value of 76.93 with a standard deviation of 8.925. And after the t-test was carried out on the post-test data of the experimental and control classes, which was used to see whether there was an effect of Blended Learning on the motivation to learn mathematics in class XI TBSM students of SMK Negeri 1 Angkola Timur, it was found that the t-count = 2.602 and t- table = 2.042 for the significance level = 0.05. This shows that the value of t-count > t-table is 2.602 > 2.042 then Ho is rejected and Ha is accepted.
