<![CDATA[The purpose of this research is to determine whether or not blended learning models increase students' capacity to learn independently. For this study, we used a convenience sample of eighth graders from SMP Karya Utama Dolok Masihul for the 2022-2023 school year as both the population and the sample. Questions and questionnaires were used to collect information for this study. The average score on the pretest was 38.4, the average score on the posttest was 61.1, and the average score on the questionnaire was 70.4. Based on the study's findings, it is known that students at SMP Karya Utama Dolok Masihul using a blended learning model on student learning independence obtained a mean score of 61.11. This means that students' learning outcomes are still classified as relatively low. Reasons for this include students' own lack of motivation to learn and the inability to participate in hands-on learning activities due to a lack of access to mobile devices. The study's author concluded that schools could do better to incorporate technological advances into their teaching and learning of mathematics. As a means of ensuring that both educators and students remain abreast of evolving technological capabilities, and to pique students' curiosity and motivate them to learn more on their own accord.]]>

<![CDATA[The purpose of this study was to analyze the influence of the GeoGebra-assisted inquiry learning model on the mastery of the concept of geometric transformation of grade IX students at Taman Siswa Galang Junior High School. The design of the Pretest-Posttest Control Group is used in quasi-experimental methodologies (pseudo-experiments). Class IX-B as an experimental group and obtained a GeoGebra-assisted inquiry learning model, while class IX-C as a control group and received traditional method treatment, with the number of students at Taman Siswa Galang Junior High School as many as 75 people. Careful observation, testing, and documentation form the basis of the data we collect. Significant differences in students' ability to understand mathematical concepts were found between the experimental and control groups, as determined by the research findings. The average posttest value for the experimental group was 86.20 and for the control group was 77.10. Ho was rejected and Ha was accepted at a significance level = 5% based on the test results obtained by calculating the > ttabel (3,431 > 2,011), so that it can be concluded that the average ability to understand mathematical concepts of experimental class students who were treated with a GeoGebra-assisted inquiry learning model was better than the average ability of control class students who were treated with conventional methods.]]>

<![CDATA[The goal of this research is to assess how students' mathematical literacy is affected by a realistic mathematics education approach supported by a media blog. Of the 90 students grade 7 Laboratories of MTs UINSU Medan as a population, a total of 68 students served as the sample. The sample consist of two classes, one class as the experimental class where RME was implemented, and the second class as the control class where conventional learning that is Direct Instruction was applied. The instrument used was a test of mathematical literacy skills in the form of a pre-test and a post-test in narrative form on Algebra material. The methodology used in this study is quantitative. Independent sample t-test in SPSS 25 is used to analyze the data. The findings indicated that compared to students who received traditional instruction (Direct Instruction), those who received RME-based instruction showed statistically significant gains in mathematical literacy (P-value 0.035<0.05).]]>

<![CDATA[Based on the background of the problem in this research, namely the low numeracy literacy skills of class VII students at MTs Darul Mukhlisin Islamic Boarding School due to their lack of ability to learn and participate actively in mathematics lessons, the learning model applied so far seems monotonous which is still centered on teachers and mathematics learning at MTs Darul Mukhlisin Islamic Boarding School, especially in algebra form material, has not implemented the Mathway application. This study aims 1) to determine the effect of the Project Based Learning learning model on the numeracy literacy skills of seventh grade students at MTs Ponpes Darul Mukhlisin, 2) To find out the effectiveness of using Mathway application on numeracy literacy skills of seventh grade students at MTs Ponpes Darul Mukhlisin. This research method uses a combination method (mixed methods), namely a quantitative approach using tests and a qualitative approach using questionnaires to conclude the research results.Based on the results of the t test calculation, it is known that tcount> ttable (10.168> 2.120), then H0 is rejected and H1 is accepted at the significance level α = 5%, so it can be concluded that there is a significant effect of the Project Based Learning learning model assisted by the mathway application on the numeracy literacy skills of VII grade students of MTs Darul Mukhlisin in 2023-2024. Based on students' mathematics skills assisted by Mathway Application using student questionnaire responses, the average value and percentage of each was obtained in the "Very Good" category and the "Good" category. so that the overall score was 1304 and an average of 3.62 with a percentage of 91% in the "Very Good" category. Questionnaires are used to determine student responses or responses to mathematics skills using the Project Based Learning (PjBL) model assisted by the Mathway Application at MTs Darul Mukhlisin.]]>
