<![CDATA[The low ability of students' mathematical understanding, is influenced by the lack of interest of students in mathematics so that it eliminates the continuing curiosity. Then the students are less active in solving the questions given by the teacher. This study aims to determine the effectiveness of the RMS (Reading, Mind Mapping, and Sharing) model with the help of the Powtoon application in improving the mathematical understanding ability of students of class X IPS SMA Negeri 1 Lirik. This type of research is a Quasy Experiment Design research. The sampling technique is random sampling. After the samples were taken randomly, class X IPS 1 was chosen as the experimental class and X IPS 2 as the control class. The instrument in this research is a test of mathematical understanding ability. The data analysis technique used the Paired Samples T-Test (t test) by carrying out normality tests and homogeneity tests as prerequisite tests. The results of the hypothesis obtained a significance value = 0.000 and = 0.05. Because sig. < or 0.000 < 0.05, then accept H_1 and reject H_0. It was concluded that the RMS (Reading, Mind Mapping, and Sharing) model with the help of the Powtoon application was effective in improving the mathematical understanding ability of class X Social Studies students of SMA Negeri 1 Lirik.Keywords: RMS Learning Model, Powtoon Application, Mathematical Comprehension Ability. ]]>

<![CDATA[This research begins with the results of interviews and observations which show that the value of students' mathematical critical thinking skills in class VII SMP Negeri 1 Sungai Lala is still low and there are differences between female students and male students in the process of solving the exercises given by the teacher. The purpose of this study was to determine whether there is a difference between critical thinking skills based on gender differences. This type of research is descriptive qualitative research. The subjects in this study were four students consisting of two female students and two male students, in which the four students were selected based on their critical thinking ability scores. The research instruments were questionnaire sheets and test questions. The data obtained will be analyzed by means of data reduction, data presentation, and data verification. Based on the results of the study showed that the results of the questionnaire percentage of critical thinking skills for female students were higher than for male students. The percentage results obtained were 50.77% for female students and 49.23% for male students. The completion of critical thinking ability test questions between female students and male students has differences. Female students have been able to master the five indicators of critical thinking skills in solving test questions, while for male students there are two indicators of critical thinking abilities that they have not yet mastered. In terms of conclusion, that female students have excellent critical thinking skills while male students have good critical thinking skills.]]>

<![CDATA[This research is motivated by the low ability of students to understand mathematical concepts. The Auditory Intellectually Repetition (AIR) learning model can be used as an innovative teaching solution in improving the ability to understand concepts because the Auditory Intellectually Repetition (AIR) learning model is a learning model that emphasizes three aspects, namely learning by listening, learning by thinking and repetition. This study aims to determine the effectiveness of the Auditory Intellectual Repetition (AIR) learning model in improving students' understanding of mathematical concepts. The design of this research is Pre Experimental with the form of research used is One Group Pretest-Posttest Design. The sampling technique used is Simple Random Sampling. After the samples were taken randomly, class X IPA 2 was chosen as the experimental class. The instrument in this study was in the form of a student's mathematical concept understanding ability test. The data analysis technique in this study used N-Gain data and the Paired Sample T Test (t test). Based on the average N-Gain value, it can be concluded that the Auditory Intellectual Repetition (AIR) learning model is effective in improving students' mathematical concept understanding abilities. Penelitian ini dilatarbelakangi oleh masih rendahnya kemampuan pemahaman konsep matematis siswa. Model pembelajaran Auditory Intelletually Repetition (AIR) dapat dijadikan suatu solusi pengajaran yang inovatif dalam meningkatkan kemampuan pemahaman konsep karena model pembelajaran Auditory Intellectually Repetition (AIR) merupakan model pembelajaran yang menekankan tiga aspek, yaitu belajar dengan mendengar, belajar dengan berfikir dan pengulangan.
