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

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
