Abstract

This study aims to evaluate how students of class XI TKR 2 SMK Nurul Hidayah Pasundan develop their mathematical problem-solving skills using a problem-based learning technique on the topic of matrix determinants. This research is a classroom action research. The 2021–2022 school year's odd-numbered semester was employed for this study. There were 15 students of class XI TKR 2 who were used as research subjects. The following are the steps in this research: (1) Planning, (2) Action Implementation, (3) Observation and Evaluation, (4) Reflection. A learning outcome assessment used in this study measures students' ability to solve problems in relation to the determinants of the matrix., that is: (1) initial test, (2) first cycle test and second cycle test, (3) final test, and ( 4) observation sheets for researchers and students. The learning scenario had to be met by more than 80% of the activities performed in this study, and more than 80% of the individual students had to receive a score of at least 75. According to the study's findings, students in class XI TKR 2 at SMK Nurul Hidayah Pasundan can increase their capacity to solve mathematical problems by employing a problem-based learning approach when studying matrix determinants.

Abstract

This research uses a quantitative research that aims to determine whether there is an effect of Blended Learning using Flipped Classroom model on students’ mathematical reasoning abilities on the linear absolute value inequality of one variable. The type of research used is experimental research in a  quasi experimental from with a nonequivalent control group design. The population of this research were all tenth graders of SMA Negeri 4 Pematangsiantar for the academic year 2022/2023 as many as 357 students. Sampling using purposive sampling technique, while the samples from this research were taken X-PMIA 5 as the experimental class and X-PMIA 6 as control class. The instrumen used is a test of students’ mathematical reasoning abilities in the form of description of 5 equestions. The data analysis technique used to see the effect is using an Z-test, after calculating, obtained Z_hit=2,884 dwith a significant level of 0,05 then obtained Z_tab=1,64. Thus its is known that  〖Z_hit>Z〗_tab is 2,884>1,64 so can be concluded that there is an effect of Blended Learning using Flipped Classroom model on students’ mathematical reasoning abilities on the linear absolute value inequality  one  of variable.

Abstract

Students' ability to understand concepts is closely related to reasoning, communication, and problem solving skills. So a good understanding of concepts will help students achieve their learning goals well. This study aims to analyze and describe students' ability to understand mathematical concepts in the application of blended learning. The subjects in this study were class VIII students at SMPN 1 Sepatan, Kab. Tangerang. This type of research is descriptive qualitative. The procedures used in this study include the preparation, implementation, data analysis, and preparation stages. Data analysis techniques used in this study include Data Reductions, Data Display, and Conclusions. The results of this study there are differences in each indicator of the ability to understand students' mathematical concepts, not all indicators are met quite well. Blended learning has a good effect on the ability to understand students' mathematical concepts, this is due to face-to-face learning where students get a direct explanation of the material. This blended learning learning model is an effective and efficient learning in the implementation of distance learning.

Abstract

The implementation of this research was carried out with the aim of analyzing what mistakes students made when solving line and angle problems through online learning. The type of research used is descriptive and qualitative methods. The subject of the study was 25 students of class VII at one of the SMP Negeri 3 Parongpong for the 2020/2021 academic year. The results obtained by processing analytical data with techniques carried out by calculating the percentage of student errors. The instrument presented to students is in the form of 6 description test questions. From the results of the analysis experienced by students, namely students are not careful in understanding the question of lines and angles, students are not able to describe or solve problems. Thus, it can be concluded that students can answer the questions correctly, but some do not by solving them.
