<![CDATA[This study aims to identify and describe student errors in working on a two-variable system of linear equations in class VIII SMP students. This study uses a qualitative descriptive research with a description test instrument consisting of 3 questions using the level of thinking ability Bloom's Taxonomy, namely, C3 represents middle-level ability and C4 and C5 represents higher-order thinking ability. The subjects in this study were 17 students of class VIII of one of the public junior high schools in West Bandung Regency. This study uses Polya's analytical theory to interpret the results of the data presented in the form of a percentage based on the stages of difficulty in solving story problems. The results of this study show that the interpretation of the difficulties experienced by students in getting interpretations at the Bloom Taxonomy level C3 is good, C4 and C5 is lacking, with errors that are influenced by student errors, namely: conceptual errors, errors in translating story questions, incomplete mastery of material, mistakes in steps. solutions and errors in calculations.]]>

<![CDATA[This study aims to analyze the difficulties of class VIII junior high school students in working on statistical problems through online learning. The method used in this research is descriptive qualitative research method, by giving a test in the form of a description consisting of 3 questions using Bloom's taxonomic thinking ability level. The subjects in this research were students in class VIII at SMPN 6 Cimahi, totaling 17 students. The data collection technique used in this study is in the form of test results with Bloom's taxonomic ability level. low-level abilities represent C3, C4 and C5 represent moderate-level thinking skills and C6 represent high-level thinking. The results of the interpretation of the difficulties that students face in solving statistical problems are C3 got a good interpretation, C4 and C5 with less interpretation. Difficulties that affect students in solving problems on statistical material are lack of understanding of concepts, completion steps, incomplete mastery of the material, and errors in calculations. In addition, during the current pandemic, there are other non-technical obstacles such as the difficulty of accessing the internet for students living in remote areas.]]>

<![CDATA[This research is motivated by the low understanding of students' mathematical concepts due to the lack of active participation of students during the learning process. The purpose of this classroom action research is to examine the increase in the ability of students to understand concepts in mathematics learning about Relationships and Functions using the Scientific approach. This research was conducted on 20 students of class VIII SMP Advent Cimindi. This classroom action research was designed in 2 cycles consisting of 4 meetings. The procedure in each cycle includes the stages: planning the action, implementing the action, observing and reflecting. The effectiveness of the action in each cycle is measured from the results of observations of students and teachers during learning and from student learning evaluations. The results showed that the application of a scientific approach could improve students' ability to understand mathematical concepts. This is indicated by an increase in student learning completeness from the first cycle to the second cycle. In the first cycle, the level of student learning completeness reached 55% and in the second cycle increased to 90%. So it can be concluded that learning with a scientific approach can improve students' ability to understand mathematical concepts.]]>
