Abstract

This study aims to determine the effect of the Discovery Learning model assisted by E-LKPD on students' physics learning outcomes. The research was conducted at SMA Negeri 1 Percut Sei Tuan. This type of research is a quasi-experimental design with a pretest-posttest control group design. The sampling technique used in this study was cluster random sampling, consisting of an experimental class and a control class, each with 36 students. The solution to address the research problem was to apply the Discovery Learning model assisted by E-LKPD in the experimental class and conventional learning in the control class. The subjects of this study were students in classes X-3 and X-4. The instrument used was a learning test in the form of 15 multiple-choice questions. Before the different treatments were applied, a pretest was conducted, resulting in an average pretest score of 48.1 for the experimental class and 45.6 for the control class. Normality and homogeneity tests on the pretest data indicated that both classes' data were normally distributed and homogeneous. The two-tailed t-test resulted in a value of tcount < ttabel = = 0.97 < 1.994, which means H0 was accepted, indicating that the initial critical thinking ability of the experimental and control classes was the same. After the different treatments, a posttest was conducted for both classes, which resulted in an average posttest score of 76.5 for the experimental class and 63.5 for the control class. Normality and homogeneity tests on the posttest data showed that both classes' data were normally distributed and homogeneous. The one-tailed t-test resulted in tcount < ttabel = = 4.860 > 1.666, so the alternative hypothesis (Ha) was accepted. It can be concluded that the use of Discovery Learning assisted by E-LKPD has a significant effect on students' learning outcomes on the topic of work and energy in class X at SMA Negeri 1 Percut Sei Tuan.

Abstract

Understanding of Mathematics concepts is an important factor in determining students' learning success. However, the results of observations at SDN 33 Kalumbuk showed that fifth grade students still had difficulty in understanding Mathematics concepts. This can be seen from the low level of learning completion, which was only 36.84% in class VA and 33% in class VB. The low understanding of concepts is caused by the lack of interactive learning methods, so that students get bored easily and are less involved in the learning process. This article discusses the importance of understanding concepts in Mathematics learning and solutions that can be applied to improve student understanding. One of the proposed strategies is the use of the Make a Match learning model, which can increase student engagement and help them understand concepts more concretely and interestingly. In addition, problem-solving approaches, the use of visual media, group discussions, and continuous evaluation can also be applied to improve learning effectiveness. By implementing innovative and interactive learning methods, it is hoped that students' understanding of Mathematics concepts can improve, so that they are better prepared to face academic challenges and are able to apply Mathematics concepts in everyday life.

Abstract

This study discusses the history and development of the number system in India and its influence on the evolution of mathematics worldwide. The Indian number system has evolved since the Indus Valley Civilization and has undergone significant innovations, such as the invention of the number zero by Brahmagupta and the development of the place value system, which forms the basis of the modern decimal number system. This research employs a qualitative method with a library research approach, involving the analysis of various written sources, such as books, academic journals, and historical articles on the Indian number system. The findings indicate that the Indian number system has had a profound impact on the advancement of mathematics, particularly after it was introduced to the Islamic world by scholars such as Al-Khwarizmi, who later disseminated it to Europe, making it the foundation of the numerical system used today. Additionally, the Indian number system contributed to the development of various branches of mathematics, including algebra, calculus, and number theory, and served as the foundation for modern technology, including computers and calculators. Therefore, understanding the history of the Indian number system should be reinforced in mathematics education, accompanied by further research on its applications in contemporary science and technology.

Abstract

Mathematical connection ability is a crucial competence that should be developed from the elementary level, as it helps students understand the interrelationships between mathematical concepts and their applications in daily life. This study aims to analyze the mathematical connection abilities of first-grade elementary school students in learning flat shapes. The research employed a descriptive quantitative method using cognitive and psychomotor assessment instruments. The cognitive test consisted of multiple-choice and essay questions measuring students' ability to recognize, understand, classify, and apply flat shapes. The psychomotor test involved tasks such as assembling flat shapes into meaningful objects and classifying shapes by type. The results showed that students were fairly capable of identifying and grouping flat shapes, but had difficulty explaining classification reasons or relating shapes to real-life objects. The psychomotor results also indicated that fine motor skills and the ability to make real-world connections need improvement. These findings highlight the importance of contextual learning approaches and the use of concrete media to strengthen students’ mathematical connections from an early age.

Abstract

This research aims to examine the learning methods and challenges faced by several students when solving mathematics problems regarding number patterns, with an emphasis on analyzing students' thinking processes. This study employs an approach to analyze students' ways of thinking. In this study, a qualitative approach is used with a case study method on a group of junior high school students. Information was collected through observations and analysis of students' work. The findings of the research indicate that students apply various strategies in understanding the material of number patterns, which include memorizing patterns to trying to find their own formulas. However, many students face difficulties in drawing conclusions about patterns and connecting relevant mathematical concepts to everyday life. Common mistakes include errors in recognizing patterns, errors in calculations, and a lack of precision in understanding problems. Analysis of the thinking process shows that some students are still at the concrete operational thinking level, so they need visual aids and real-life examples to better understand patterns. This research emphasizes the need for an approach in teaching that can enhance students' abstract thinking abilities and requires varied practice in determining numerical pattern problems.
