This study aims to identify types of errors made by students and their conceptions related to the concept of relations and functions. This research is a descriptive study with a qualitative approach conducted in eight grades at one of Madrasah Tsanawiyah in Kabupaten Bandung Barat. The research subjects were taken from 26 students who answered incorrectly on a given test. The research instrument was in the form of a diagnostic test based on basic competencies and indicators in the Relations and Function material. In-depth interviews were conducted with students who made mistakes in answering. Based on the data analysis, the mistakes made were: 1) conceptual error type 1, 2) conceptual error type 2, 3) procedural error, 4) technical error, and 5) error in understanding the problem. One of the causes of students' mistakes is the dissimilar concept between students’ and scientific conceptions.

This research is based on the background that the importance of social arithmetic lessons for students in mathematics lessons even though during the COVID-19 pandemic, even though social arithmetic is a material that is closely related to everyday life and aspects in it, students are expected to be able to master it. to solve a problem. The purpose of this study was to analyze and describe the difficulties experienced by students when solving social arithmetic problems. This type of research is descriptive qualitative. The first research stage is reducing the data, then presenting the data and finally drawing conclusions. The subjects in this study were students of class VIII SMP Negeri 10 Cimahi as many as 32 students. The instrument used is a test question consisting of 5 description questions arranged based on cognitive level with details from C2 to C5. The results of this study indicate errors that vary, including errors in understanding the concept of material and questions, due to lack of accuracy, and errors in working principles. So it can be concluded that students are still difficult to understand concepts, as well as thoroughness in understanding questions so that they cannot solve problems properly and with appropriate results, students have many difficulties in question number 5, bloom C5 cognitive level on indicators of determining and solving daily problems about a discount of 51.3%.

This research was conducted with the aim of analyzing students' difficulties in the material on the flat side. Using a qualitative descriptive research method with samples from this study, 10 students of class VIII MTs Darul Falah for the 2020-2021 academic year. For data collection using instruments in the form of 5 items that have been adjusted to the indicators. Furthermore, student answers are analyzed to find out student errors based on predetermined indicators. Of the five indicators, there are three indicators belonging to the highest level of difficulty, namely the indicator for calculating the volume of the prism, the indicator for analyzing problems related to the volume of the pyramid and the indicator for analyzing problems related to the area of the beam. The percentages are 81.63%, 91.83% and 79%, respectively. With the following error factors: (1) memorizing the formula without understanding the concept of solving the problem; (2) the difficulty of students in sketching problem solving; (3) students' carelessness in calculating math problems; (4) students' lack of accuracy in solving mathematical problems.

Reflective thinking ability and mathematical disposition in mathematics learning is very important to be improved. Reflective thinking ability can help students to get more optimal learning outcomes and mathematical disposition is required by students to solve a mathematical problem. The purpose of this study is to analyze the difficulties faced by junior high school students in working on the problem of reflective thinking ability that review based on students' mathematical disposition ability. The research method used is descriptive analysis method to analyze the available data and processed so as to obtain a clear description of the facts and the relationship between the phenomena studied. The sample in this research is the students of class IX B in SMPN 5 Cimahi. The results of this study is that almost allindicators ofreflective thinking abilityare still not achieved review bases on student’smathematical disposition. this is due to the following factors : (a) mathematic material that is still poorly understood so that students have difficulty when solving difficult mathematical problems ; (b) student made a mistake in concept when do reflective thingking ability test; (c) the student has never experienced a test with reflective thinking ability before.

The purpose of this reseach is to analyze student learning outcomes on the material of a two variable system of linear equations by using a scientific approach assisted with learning videos. This reseach is classroom action reseach which is carried out in 2 cycles. In the first cycle of learning using a scientific approach without using learninh videos, while in the second cycle of learning using a scientific approach with the help of learning videos. The targets in this study were class VIII in one of the MTs in Bogor district. Collecting data based on the result of observations and student learning outcomes test sheets based on idicators of student competency achievement on the achievement of KKM scores by providing 5 item of description. From the test results it can be concluded that there is an increase in student learning outcomes in solving problems on the material of a two variable linear equations system in the form of a story. In the first cycle the students who completed the KKM were 50% while the students who completed the KKM in the second cycle were 90% of the total 20 student.
