This study aims to improve the learning process to improve the mathematics learning outcomes of students in class XI IPS SMA Persada Pebenaan for the 2020/2021 academic year through the application of the Discovery Learning learning model. Collecting data involves observing the activities of teachers and students in action. This classroom action research consists of two cycles, each consisting of 3 meetings and one repetition. By applying the Discovery Learning model with a scientific approach, students must be more active in discovering concepts and materials to increase student learning activities. It was proven that the number of students who achieved KKM increased from cycle I to cycle II. In cycles I and II, students who pass the KKM have a success rate of 20% and 70%, respectively. Based on the research findings, the mathematics learning outcomes of class XI SMA Persada Pebenaan can be increased in the material for sequences and series using the Discovery Learning model.

Crossroads in Mathematics Games: Integrating Indigenous and Exotic Games

Michael Tangkur, Clement Ayarebilla Ali — Sun, 30 Jun 2024 01:24:15 +0000

In numerous countries and higher education institutions, the significance of indigenous games in mathematics education is highly recognized. Nonetheless, the increasing preference for exotic games has placed indigenous mathematics teachers in a challenging position. This research aimed to examine the awareness and understanding of mathematics teachers regarding indigenous games amidst this competition. Initially, the study employed a phenomenological approach, targeting 200 teachers but randomly selecting a sample of 70 for the quantitative phase. Subsequently, the qualitative phase involved in-depth interviews and observation checklists with five teachers to explore the issue further. The collected data was systematically coded and thematically analyzed, focusing on teachers' knowledge, misconceptions, and potential solutions. The findings revealed that some teachers had greater knowledge of indigenous games than exotic ones. Conversely, other teachers believed that exotic games facilitated faster learning outcomes. This divergence created a significant dilemma in choosing indigenous games for mathematics instruction. Despite the popularity of games like draft, playing cards, snake-and-ladder, and Ludo, the teachers ultimately recognized that Indigenous games such as biloo, bilore, gollaa, and mullaa provided superior learning outcomes. Therefore, stakeholders were recommended to revamp mathematics curricula to incorporate indigenous games more effectively.

This study was motivated by the low mathematics learning outcomes of SMK Negeri 1 Bayah students. It is necessary to apply learning media that helps improve students' abilities. One of the learning media used is the Domino Matrix Card. This study aims to determine the learning outcomes of students who received treatment using matrix domino cards compared to students who were not given the treatment of learning using matrix dominoes. The results showed that the learning outcomes of students who were treated using matrix domino card media were higher than the learning outcomes of students without using matrix domino card media. The results of the statistical test showed that the learning interest of students utilising the matrix domino card media in the experimental class obtained an average = 67.78 and standard deviation = 20.88 while learning without using the matrix domino card media in the experimental class obtained the average data of students' learning interest = 49.72 and standard deviation = 15.48. After the t-test obtained the results that t count > t-table, which is 1.80> 0.354, the results of hypothesis testing obtained are t count > t-table, then Ha is accepted, meaning that there is an increase in student learning outcomes using matrix domino card learning media in class XI SMKN 1 Bayah 2019/2020 academic year.

This research and development (R&D) aims to produce an electronic Student Worksheet (E-LKPD) on straight-line equation material based on discovery learning that qualifies as valid and practical. This type of research is development research with the 4-D development model (Define, Design, Develop, Disseminate). Data collection instruments involved validation sheets and student response questionnaires. Data analysis techniques used include validity and practicality analysis. The E-LKPD validation results were 89.28% with very valid criteria. E-LKPD testing in small groups resulted in a practicality level of 83.82%, categorized as practical, while testing in the big group reached 82.004%, with practical criteria. The data analysis concluded that the discovery of learning-based E-LKPD on straight-line equation material has complied with the validity and practicality standards. Accordingly, the developed E-LKPD can be used by students in grade VIII.

This research aims to produce valid and reliable phase E mathematics higher-order thinking Skills (HOTS) questions on quadratic equations and functions. The research conducted by researchers in development research with the development model used, namely the type of development studies with two stages, namely preliminary and formative evaluation. The subjects of this study were students of class X SMAN 2 Karimun. In this study, the average score of the assessment of the three aspects (material, construct, and language) by the three validators was 86.16%, with a very valid category. In contrast, the average of all statements in the student response questionnaire was 88.33% with very good criteria and had a reliability value of 0.89 with a high category. This study concluded that the resulting 22 questions of Higher Order Thinking Skills (HOTS) mathematics phase E on the material of equations and quadratic functions developed have met the valid and reliable criteria.

Development of Realistic Mathematics Education-Based Learner Worksheets (LKPD) to Enhance Higher-Order Thinking Skills in Grade IV Students of SD/MI

Annisa Febriyani, Habudin, Wida Rachmiati — Mon, 22 Jul 2024 06:54:14 +0000

This study aims to determine the development procedures, feasibility, and effectiveness of mathematical worksheets based on realistic mathematics education to develop high-order thinking skills of fourth-grade students in SD/MI. This research is a research and development (R&D) research using a 4D research model consisting of 4 stages, namely the Define, Design, Development, and Disseminate. The data instruments used in this study were interview observations. The subjects of this study were the fourth-grade students of SDN Sukatani VI, totaling 35 students. The data analysis was qualitative and quantitative. Qualitative data analysis was obtained from observations and interviews, while quantitative data analysis was obtained from expert validation, teacher response questionnaires, and student response questionnaires. The validation results of mathematic education experts, with a percentage of 83%, were categorized as "Good/Valid". Based on the teacher's response, the research results obtained 96% categorized as "Very Good/Decent," and student responses obtained by the assessment results with a percentage of 90.28% categorized as "Very Good" to use.
