Abstract

This study aims to explain students pseudo-thinking errors on mathematical problem-solving skills  that are reviewed supported on high, medium, and low self-confidence. This research was conducted at SMAN 60 Jakarta class XI MIPA II for the 2020/2021 academic year. The subjects taken were 3 out of 38 students. This research method is a descriptive qualitative approach. Researchers used self-confidence questionnaires, problem-solving ability tests, and interviews. The material being tested is the derivative of algebraic functions. The results obtained stated that students with high self-confidence scored perfect test scores but there were a few writing errors. The completion step, therefore, included pseudo-correct thinking. Students with moderate self-confidence can do the questions well, but there are inaccuracies so that the results are wrong. Therefore, students with moderate self-confidence enter the indicator of pseudo-wrong thinking errors with information that can reflect on their answers. In students with low self-confidence, they face errors in compiling the completion steps but can rectify and find the correct answer. With this, students with low self-confidence fall into the indicator of pseudo-correct thinking errors with information on understanding the wrong concept.

Abstract

This study was conducted to compare the two methods of PBL and Ethnomathematics on students' creative thinking skills, and creative thinking abilities in terms of students' initial mathematical abilities. This study aims to determine which learning methods are superior in creative thinking skills. This study uses a quantitative method with a quasi-experimental type of research. The method of data collection is through the initial mathematical ability test and creative thinking ability test. The research subjects are class VII 8 and VII 9 SMP in Kab. Bekasi for the 2022/2023 academic year. Based on the results of the study, it was found that the average value of students in the ethnomathematics class was better than the PBL class. However, for students with high KAM, the PBL method is more effective, because it is proven that the final score of students is higher in the PBL class. Students with medium and low KAM are better at using the ethnomathematical method for their creative thinking skills.

Abstract

When learning in school when students are given a problem, of course each student gives a different answer, this shows that each student has a different intelligence in solving this problem. We call these different intelligences as multiple intelligence. Each question must of course be solved with intelligence, especially in learning mathematics, students often find it difficult to solve problems in the form of stories that are related to everyday life. Connecting problems in mathematics with everyday life is one indicator of the ability to connect mathematics. Indirectly, students who have difficulty solving math problems associated with everyday life cause the students to have low mathematical connection skills. This study aims to see whether there is a relationship between multiple intelligence and students' mathematical connection abilities. The research method used is an associative quantitative research method with the spearman rank correlation test. The instruments in this study were a statement questionnaire to measure multiple intelligence and a test question instrument to measure students' mathematical connection abilities. This study involved 97 samples from class VIII students at SMP Puspanegara Citeureup. The results of the analysis in this study indicate that there is a significant relationship between multiple intelligence and the Mathematical Connection Ability of grade VIII students at SMP Puspanegara Citeureup. This is evidenced by the coefficient of the relationship between multiple intelligence and the students' mathematical connection ability of 0.720. Based on the interpretation of values, it shows that there is a strong relationship between multiple intelligence and the ability of mathematical connections. Keywords: multiple intelligence, mathematics, connections.

Abstract

The role of the teacher is not only teaching but also training other academic skills such as solving OSN questions. It would be a shame if the teacher could not guide students in solving OSN questions. According to DKI Jakarta Elementary and Elementary Education data, there has not yet been a Muhammadiyah school that has won OSN, both at the Kotip level, let alone at the provincial and national levels. This Community Service activity aims to increase the competence of Muhammadiyah Middle School Mathematics Teachers under the auspices of the Jakarta PWM Elementary Education Council to guide students in solving OSN questions. The training activities include: (1) the prites stage; (2) the difficulty analysis stage; (3) the stage of giving tricks; and (4) the percentage stage. This activity has been carried out and received good enthusiasm from partners. Partners in this case are Mathematics teachers at Muhammadiyah Middle Schools throughout DKI. It is proven that there was an increase in the teacher's ability to work on OSN questions that occurred in this training. This can be seen from the more participants who were able to do the Posttest questions correctly after being given training by UHAMKA Mathematics Education lecturers. The seriousness of the participants in this training was evident from the collection of video presentations that were sent by the participants as many as 5 videos a day.
