This study aims to describe the increase of students' mathematical understanding ability in learning the two-variable linear equation system (SPLDV) and the two-variable linear inequality system (SPTLDV) with Android GeoGebra media reviewed by gender. This experimental quasi research is one group pretest postest design. The sample in this study was a class XI of 32 students with Purposive Random Sampling techniques. Data collection in this study uses an instrument for a mathematical understanding ability test in the form of a description. The results of the study can be concluded in the learning of Android GeoGebra, the mathematical understanding of male students is significantly different from the mathematical understanding of female students. It means that in learning the Android GeoGebra Improvement of the Mathematical Understanding Ability of Male Students is greater than female students. Thus it can be concluded that in the learning of Android GeoGebra, an increase in the mathematical understanding of male students is better than female students.

Mathematics is a subject closely related to everyday problems; the low PISA scores from all fields have made the government make breakthroughs to improve literacy and numeracy skills through the AKM. The purpose of this study was to analyze the characteristics of numeracy skills in solving AKM problems. The type of research used is qualitative with a phenomenological design. The subjects of this study used one mathematics teacher and three eighth-grade students of SMP Muhammadiyah Al Kautsar PK Kartasura Sukoharjo for the 2021/2022 academic year. Using a purposive sampling technique in taking the subject, this study used three students of class VIII as the main subject of the study. In addition to the researcher as the key instrument, the researcher also used AKM questions, interview texts, and observation texts for data acquisition. The validity used is the triangulation of sources and techniques. The inductive technique is the process of data analysis used in this research. The results of the study stated that students' numeracy skills were not perfect, indicator three on giving conclusions was not given for all subjects used. Habituation in solving AKM problems in classroom learning is needed to train students' numeracy skills.

<span>This study aims to determine the effect of the NHT and TPS learning models on mathematics learning outcomes, the impact of student learning styles on mathematics learning outcomes, and the result of the interaction of learning models and student learning styles on mathematics learning outcomes. This type of quantitative research with a quasi-experimental design. The research sample consisted of two classes (experimental and control) which were taken using Cluster Random Sampling from the population of all course VIII students of SMP 4 Muhammadiyah Surakarta in the academic year 2021/2022. Data collection techniques with questionnaires and tests. Before the research, a balance test was conducted to determine whether the two samples had the same initial abilities. The normality test and homogeneity test are prerequisite analysis tests in this study. The data analysis technique using two-way cell analysis of variance is different, with a significance level of 5%. The results showed that the NHT and TPS learning models affected mathematics learning outcomes. The mathematics learning outcomes of students who were given the NHT learning model tended to be better than those who were given the TPS learning model. Learning styles affect the results of learning mathematics. Students with an auditory learning style get better learning results than visual and kinesthetic learning styles. The interaction between the NHT and TPS learning models on mathematics learning outcomes in terms of student learning styles</span>

The COVID-19 pandemic has changed the online learning process from offline to online. One of the references for measuring digital literacy levels is to directly observe the learning process that occurs using platforms that support distance learning. The purpose of this study was to analyze the digital literacy skills of elementary school students in the use of distance learning media and analyze the understanding of digital media of elementary school students in the use of distance learning media. The method used is qualitative with a phenomenological design. Data collection techniques using interview techniques, field observations, and documentation. The data validity technique uses source and technique triangulation. At the same time, the data analysis technique uses an inductive step. The results showed that the students of SD N 1 Brajan had a good level of digital literacy; students knew the benefits of digital media used as learning media, such as understanding the help of the media features used for practical benefits. Meanwhile, in applying digital media, students can also use it as a learning medium. This is because students are used to using these media in everyday life. In contrast, some students have difficulty applying digital media because they have the reason that the cellphones they use are still alternating with their parents, so the infrequent use of digital media will affect students' digital literacy skills. Teachers can make efforts to improve students' digital skills by providing learning media that can provide additional learning in the use of learning media that are foreign to students.
