Abstract

During the Covid-19 pandemic, learning is carried out online, this does not become an obstacle for learning mathematics, especially on the subject of social arithmetic which is closely related to daily activities. The purpose of this study is to analyze and explain students' mistakes when working on social arithmetic problems online. The research method uses descriptive qualitative. Data collection techniques by distributing 5 items of description. The subjects in the study were seventh grade students of Dharma Kartini Middle School, Cimahi. The research stages include data reduction, data delivery and data inference. The results of this study show an error in indicator one determining the relationship between selling and buying prices and indicator two determining the relationship between profit and loss in the low category, indicators of the relationship between net, gross and tare and indicators solving problems related to social arithmetic in the medium category and indicators solving problems with respect to discounts in the high category. The underlying factors are the lack of accuracy of students in pronouncing the questions, lack of understanding of concepts and students still not understanding arithmetic operations.

Abstract

This research is a classroom action research that aims to determine the improvement of students' mathematics learning outcomes after using a scientific approach to online learning. The research was carried out at SMP Negeri 8 Cimahi with the subjects of class IX students totaling 35 people. Collecting data in the form of student test results with a discussion of quadratic equations. This research was conducted in 2 cycles. Each cycle was carried out in 2 meetings. In the first cycle, the learning was less than optimal in applying the scientific approach and the students' motivation to learn mathematics was less. In the second cycle, the deficiencies that occurred in the first cycle were corrected. In cycle II, many students were able to solve the questions given, actively asked if there was something they did not understand and many students were able to participate in online learning using a scientific approach. The results of this study indicate that the scientific approach to online learning can be applied and an increase in each cycle has a good impact on grade IX students at SMP Negeri 8 Cimahi.

Abstract

This research goals to fix the activeness and knowing results of students using the STAD type cooperative learning model on the subject matter of algebraic function limits. The points of this research were students of grade XII RPL 2 SMK AL-Ihsan Batujajar with a total of 26 students, consisting of 9 male students and 17 female students. The instrument used in this study was the observation sheet and the test description and interview of the mathematics teacher at the school. The results of student activeness research in the first cycle of 65.38% were in the criteria of being quite active, and the second cycle at 84.61% were in active criteria. And the results of research on student learning outcomes in the first cycle is in the percentage of class completeness by 53.84% and in the second cycle is the percentage of class completeness by 92.30%, it can be seen student learning outcomes from cycle I has intensified in cycle II. Based on the research outcomes, it can be resumed that the use of the STAD type of cooperative upgrading on the subject of algebraic functional limit in class XII RPL 2 SMK AL-Ihsan Batujajar there is an influence of increasing student learning outcomes and activeness.

Abstract

This study aims to describe students mathematical critical thinking skills in solving circle problems.. This type of research is descriptive qualitative, using the subject of 12 students of class XI at MA Nurussa'adah Pakuhaji. The research data collection technique is observation. The instrument is in the form of two description test questions. Data analysis in this study uses data reduction, data presentation, and drawing conclusions. The results of the study indicate that students with high levels of critical thinking skills can perform well in all indicators of mathematical critical thinking skills, namely on indicators of interpretation, analysis, evaluation, and inference. Students with moderate critical thinking levels can achieve mathematical critical thinking indicators, namely interpretation, analysis and inference, but are still not perfect in the evaluation indicators. Students with low critical thinking levels still have not completed and fulfilled all the indicators of mathematical critical thinking.

Abstract

This research is motivated by the low use of media in learning mathematics, because students’ feel bored and difficult to understand mathematics learning. Therefore, there is a need for innovation, namely with Adobe Flash-based interactive mathematics learning media. The purpose of this research is to determine the effectiveness and impact of interactive learning media assisted by Adobe Flash at the junior high school level. This research uses a meta-analysis research design, where meta-analysis is a study of previous journals with the same problem. So that they can find out the results and conclusions. The data collection technique used in the research is written documentation of Adobe Flash-based learning media at the junior high school level. The author uses 19 articles for reference. The articles are sourced from the Google Scholar and Sinta websites. The results of the research show that Adobe Flash-based interactive mathematics learning media has a positive impact so that it is more practical and effective to use in the mathematics learning process.

Abstract

This research is motivated by the existence of teachers who have not used learning methods optimally and teachers rarely use learning media when delivering subject matter so that students' interest in learning is low. The low interest in student learning is characterized by students not paying attention to the teacher, students looking sleepy and students talking to their friends during the learning process. This study aims to describe the increase in learning interest of second grade students of SD Negeri 25 Empakan after using Powerpoint-Based Interactive Media. This study uses a qualitative descriptive approach and a form of classroom action research. The implementation process consists of 4 stages, namely: planning, implementing actions, observing and reflecting. From the results of the study obtained the average student interest in using Powerpoint-Based Interactive Media in the first cycle with a classical percentage of 52.91%. While the percentage of classical interest in learning in the second cycle increased to 97.98%. Based on the data exposure, research findings, and the discussion that has been described, it can be concluded that the use of Microsoft Powerpoint-Based Interactive Media can increase students' interest in learning.
