Abstract

Understanding concepts is an important foundation for understanding principles and theories in various fields, including mathematics. Therefore, to understand principles and theories, students need to have a strong understanding of the concepts that form the basis of these principles and theories by using tests. The focus of this research is to analyze students' solutions to problems by looking at their ability to understand mathematical concepts in one of the state junior high schools in Pesisir Bukit district, Sungai Liuk. This type of research is qualitative research with a descriptive approach. Participants in this research were 16 class VII students. Data collection was carried out using concept understanding ability test instruments, observation and documentation studies. The results of the research show that there are differences in students' ability to understand mathematical concepts in solving the multiplechoice questions given.

Abstract

The purpose of this research is to explore and introduce local culture in the form of woven crafts that contain the concept of geometry of curved surface solids, aided by GeoGebra media that can model the mathematical concepts embedded in the weaving culture. This research is descriptive in nature. From the student assessment sheets, it is evident that students have started to understand the concept of mathematics, especially in the topic of curved surface solids. In their learning, this is linked with the use of GeoGebra as a learning medium, which can serve as an effective learning resource for students in realizing cultural objects into the media used. This can enhance students' imagination in studying these solids, making it easier for them to remember and learn the material being discussed. Although there are students who do not yet understand the concept of curved surface solids in mathematics, the use of media as a learning support, especially GeoGebra, will be very helpful if a teacher uses it in accordance with the material being discussed and the needs of the students. Engaging media will attract students to learn because in this advanced era, many students are reluctant to study due to boring teaching methods. Therefore, it’s important for a teacher to create engaging learning media to attract students to learn.

Abstract

This research is motivated by the importance of developing worksheets (LKPD) that are tailored to the demands of the technological era. Therefore, the researcher developed an electronic LKPD based on Liveworksheet with the cooperative model of Numbered Head Together (NHT). This development was carried out to enhance students' mathematical problem-solving skills in the topic of curved surface solids. The researcher employed the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model, which is a systematic, structured, directed, and planned model. The research utilized a questionnaire as the research instrument, which was distributed to ninth-grade students in a junior high school (SMP). The questionnaire aimed to gather information about the characteristics of the students and their needs regarding the developed LKPD. Based on the analysis of the needs, the researcher successfully developed an electronic LKPD using the Liveworksheet platform. This LKPD product offers the advantages of efficiency and effectiveness, incorporating audio-visual elements and student discussions to enhance understanding and problem-solving abilities. The development is expected to provide an interactive and engaging learning experience, helping students to develop their mathematical problem-solving skills
