Mayang, Nirfayanti, Ernawati — Wed, 30 Oct 2024 00:00:00 +0000

This study uses a quasi-experimental method that aims to determine the improvement of mathematical communication skills of 8th grade students of MTs Al Irsyad Biringkaloro before and after the application of mathematics teaching materials based on the Inquiry Learning model. This study used an initial test (pretest) and final test (posttest) to compare students' abilities before and after learning. The research sample was taken purposively from class VIII-A. The research data were obtained through a test specifically designed to measure students' ability to communicate mathematically, and this test has been assessed as valid by experts. The data obtained were analyzed using descriptive statistics to describe the data in general, and inferential statistics (independent sample t-test) to test for significant differences between pretest and posttest scores. The results showed an increase in mathematical communication skills where the average value of the pretest was 64.15 with a sufficient category while in the posttest results 77.30 with a high category and the results of the independent sample t-test which showed that there was a positive effect of the Inquiry learning model mathematics teaching materials on the mathematical communication skills of 8th grade students of MTs Al Irsyad Biringkaloro

At the core of the activity is observing, asking questions, trying to reason, and communicating the mathematical ideas learned. The closing contains reflections by inviting students to make summaries, giving homework, then inviting students to pray, and closing the lesson with greetings.

MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS MATEMATIKA DENGAN INTEGRASI STEAM PADA SISWA SMP 27 MAKASSAR

Jeranah, Asdar, Rezki Novianti — Wed, 30 Oct 2024 00:00:00 +0000

Critical thinking skills are one of the key competencies that students must possess to face future challenges. In the context of mathematics learning at SMP Negeri 27 Makassar, mathematical critical thinking skills are essential and need to be developed to support the advancement of knowledge in the era of globalization. However, mathematics learning often does not fully focus on the development of higher-order thinking skills. A learning approach that integrates STEAM (Science, Technology, Engineering, Art, and Mathematics) can be a solution, as it allows students to understand and apply mathematical concepts in real-world situations. The integration of science, technology, engineering, art, and mathematics elements in learning creates a more creative, holistic, and relevant learning experience. This study aims to analyze how the STEAM approach can help students at SMP Negeri 27 Makassar see the connections between scientific fields and apply them to solve real-world problems, thereby enhancing their critical thinking skills. This research uses a literature review method. The analysis results show that the implementation of STEAM-based learning at SMP Negeri 27 Makassar is effective in improving students' critical thinking skills. The integration of the STEAM approach in mathematics learning makes a significant contribution to the development of critical thinking skills, preparing students to face increasingly complex and dynamic global challenges.

Herwandi Sape — Wed, 30 Oct 2024 00:00:00 +0000

This study aims to analyze the effect of using digital platforms on students' numeracy literacy skills. The research used a quantitative approach with a quasi-experimental design. The research subjects were grade XI students at PGRI Tamalate High School Makassar, with grade XI.A as the experimental group using the digital platform and XI.B as the control group using conventional methods. Data were collected through PISA standard-based numeracy literacy test and student and teacher perception questionnaires. Data were analyzed using descriptive and inferential statistics (t-test).The results showed that the use of digital platforms significantly improved students' numeracy literacy skills, with a significant difference in post-test scores between the experimental (85.14) and control (72.46) groups (p < 0.05). The questionnaire also revealed that students and teachers had positive perceptions of the use of digital platforms in learning. This finding is in line with technology-based learning theory that supports active interaction and student engagement in understanding numeracy concepts. This study recommends the continuous integration of digital platforms in learning, supported by teacher training and technological infrastructure improvements, to improve the quality of numeracy education in the digital era.

Fikri Alfiani, Muhajir, Mila Karmila — Wed, 30 Oct 2024 00:00:00 +0000

This type of research is pre-experimental research involving one class. The aim of this research is to determine learning outcomes by applying the Choose Number playing method in mathematics learning in class IV at SD Negeri 7 Tarowang. The experimental units in this research were 28 class IV students. The research was carried out over 3 meetings. The research results showed that from 28 students learning using conventional methods, there were 24 students in the incomplete category with a percentage of 85%, and 4 students in the complete category with a percentage of 15%. Classically it has not been fulfilled because the average score obtained was 52.10, whereas in learning using teaching aids there were 7 students who were in the incomplete category with a percentage of 25%, and 21 students who were in the completed category with a percentage of 75%. This means that classical learning completeness is fulfilled with an average score of 82.07 which has achieved the expected KKM of 70. Based on the results of this research, it can be concluded that the Choose Number playing method in class IV mathematics learning at SD Negeri 7 Tarowang is effectively implemented.

Herwandi Sape — Thu, 31 Oct 2024 00:00:00 +0000

ELPSA (Experiences, Language, Pictures, Symbols, and Application) learning approach is a method designed to improve students' mathematical understanding through direct experience, language use, visual representation, symbolization, and application in real life. This study aims to analyze the effect of ELPSA approach on the mathematical ability of grade XI students of SMK Permata Ilmu. The method used in this research is pretest-posttest design with a population of all students in grade XI of SMK Permata Ilmu and a sample of 32 students. Data were collected through mathematical ability tests before and after the application of ELPSA, which were then analyzed descriptively and inferentially using paired t-test. The results showed that there was a significant increase in the average student score from 55.31 (pretest) to 78.94 (posttest). The paired t-test resulted in a t-count value of 12.45, greater than the t-table (2.04) with a p-value (0.000) <0.05, so it can be concluded that ELPSA has a significant effect on improving students' mathematical abilities. These results support the application of ELPSA as an effective alternative learning method in improving students' mathematical concept understanding.
