Profil Pemahaman Konsep Matematika Siswa dalam Menyelesaikan Soal Persamaan Garis Lurus Ditinjau dari Self Efficacy

2024-04-28T01:21:59+00:00

This research aims to describe the understanding of mathematical concepts among 8th-grade students of SMP Negeri 15 Palu, specifically focusing on self-efficacy in the topic of linear equations. The type of research conducted is descriptive, utilizing a qualitative approach. The research method employed is the member-check method. The subjects selected for this study were 3 students from class VIII A of SMP Negeri 15 Palu, representing high, moderate, and low levels of self-efficacy as determined from the results of a self-efficacy questionnaire. They were subsequently administered a test on mathematical concept comprehension. The results of the research indicate that students with high self-efficacy demonstrate a very good understanding of mathematical concepts, mastering all concept comprehension indicators. Meanwhile, students with moderate self-efficacy master some indicators, and students with low self-efficacy only master the indicator of restating concepts. Thus, it can be concluded that subjects with high self-efficacy have a very good understanding of mathematical concepts, while subjects with moderate self-efficacy have a sufficiently good understanding, and those with low self-efficacy have a less adequate understanding of mathematical concepts.

2024-06-09T16:40:56+00:00

The aim of this research is to find out what Learning Obstacles are experienced by junior high school students in learning social arithmetic. The method used in this research is qualitative method. Participants consisted of seven research subjects from various state and private schools in Bandung City. Data was collected through offline tests and interviews. The results of this research show that there are at least two types of learning obstacles experienced by students, namely ontogenic obstacles and epistemological obstacles which can be seen from the students' inability to translate questions and the students' inability to master the prerequisite material. Conclusion: From the research that has been conducted, there are learning obstacles for junior high school students in social arithmetic material. The identified learning obstacles are ontogenic obstacles and epistemological obstacles. Therefore, it is very important to analyze what learning obstacles are experienced by students so that solutions can be found to reduce these learning obstacles. In terms of students, they also need to improve their mathematical literacy to be able to overcome the learning obstacles experienced by students.

Analisis Learning Obstacle Materi Persamaan Garis Lurus pada Siswa

2024-06-09T16:54:43+00:00

The primary objective of this study is to identify and examine the learning obstacles by students when learning about linear equations. Employing a qualitative methodology, the research incorporates triangulation as means of data collection, involving classroom observations, analysis of tests, as well as interviews with both students and teachers. The participants in this study were eight grade students from a specific area. Findings reveal several common learning obstacles encountered by students in grappling with straight line equations. Among these challenges, a primary issue is the insufficient grasp of fundamental algebraic concepts, including the comprehension of variables and coefficients within equations. Furthermore, difficulties arise in visualizing the correlation between straight line equations and their graphical representations, along with applying appropriate problem-solving methods. The conclusions drawn from this research offer insights into the impediments students face in learning straight line equations. To enhance student comprehension, it is suggested that educators focus on solidifying basic algebraic concepts, utilize supportive visual aids, and cultivate a learning environment that fosters students' motivation and enthusiasm towards mathematics.
