“…The following are some of the difficulties students have in understanding the concept of absolute value: a) students do not understand the definition of absolute value [7]; b) students find it difficult to determine the completion interval of absolute value equations or inequalities (especially for negative and positive signs) [4,8,9]; c) students find it difficult to apply the properties of absolute values in the problem solving process; and graphs of completion from absolute values are difficult to make [10]. Students must be able to recall several steps and follow them correctly, or else the solution obtained will be incorrect [3].…”

This study intends to illustrate how students comprehend the idea of absolute value after learning it through video media using a multi-representational approach. A descriptive research methodology is used in this study. 67 students from SMA PGRI 2 Palembang's class X participated as the study's subjects. This study was carried out in 2021-2022, during the even semester. In order to gather the data for this study, exams, interviews, and documentation were used. Using a multi-representational approach, this study aims to demonstrate how students comprehend the concept of absolute value after learning it through video media. This study employs a descriptive research methodology. The subjects of the study were 67 students from SMA PGRI 2 Palembang's class X. This research was conducted in the even semester of 2021-2022. This study's data was gathered through exams, interviews, and documentation. Data was analyzed using descriptive quantitative methods to exemplify students' comprehension. The ability to understand the absolute value is analyzed for each indicator of concept understanding ability. The indicators used in this study are defining absolute values, interpreting solution graphs from solving absolute value equations and inequalities, and solving absolute value equations and inequalities. Understanding formulations in determining solutions and solving absolute value equations and inequalities Students had excellent knowledge of the concept of absolute value after learning using a videobased multi-representation technique, according to the findings. The mean score for students' understanding of absolute value was 72.31%. As a result, using this instructional video format can assist students in comprehending absolute values.

“…The critical thinking stage of students in this study refers to (Ennis, 2015), as seen in Table 1. Students are motivated to think and solve problems when problems are interesting to them (Ashari & Ilyas, 2018). In this research, the researchers developed critical thinking problems based on the student's understanding of plan figure properties.…”

The plane figure is compulsory mathematics material at all levels of education, including junior high school. However, students still make frequent mistakes in understanding the plane figures' properties. In understanding this topic, students must have the skill to think critically. Critical thinking is a process of rational thinking before deciding or taking action in a more specific direction. Therefore, this study aims to determine students' skills in defining the plane figure's properties. The method used in this research is a qualitative research method. Tests and interviews were used to determine the students' skills in determining the properties of the plane figure. Researchers determined five indicators used to determine students' skills in determining the nature of the plane figure: focusing and formulating, observing and assessing observation results, making and assessing inductions, defining and assessing definitions, and integrating decisions. Three junior high school students were selected as research subjects with high, medium, and low skill levels, respectively. The data analysis used descriptive analysis using method triangulation and theory triangulation. The research results show two students' mathematical critical thinking patterns based on their skills. The subjects with high and medium skills can solve all problems with a small error rate and fulfill all predetermined critical thinking skills indicators. On the other hand, the subject with low skills has not been able to solve problems, so no critical thinking indicators are met. There is a misunderstanding on high and moderate skills subjects. Neither understand the meaning of opposite angles and parallel lines in specific plane figures. It can be a reference for teachers to improve students' understanding of mathematical concepts.
