The mathematical problem solving ability of class XI students at an islamic senior high school is still low. Based on the results of the initial test which was attended by 181 students, only 16,02% of students completed the KKM, while 83,98% had not. Therefore, study aims to analyses the effectiveness of PBL learning model with STEAM appr oach assisted by android application. The design of this study was quasi-experimental with a posttest-only control group design. Class XI MIPA 7 as the experimental class and class XI MIPA 2 as the control class. The data consists of tests and documentation. The test instrument is the posttest in the form of an essay. Data analysis used t-test and z-test. The results show that PBL with the STEAM approach assisted by an android application is effective in improving the mathematical problem solving abilities of class XI students on the material of sequences and series. Further research on the PBL model with the STEAM approach assisted by android applications still needs to be done, so that its application can be in accordance with the times.

Mathematics learning plays an important role in the world of education. However, the high demands for mastery of mathematics are not in accordance with current student learning outcomes. This is because learning is direct, so students' ability to understand concepts is low. This research aims to test the average ability of students to understand concepts by applying a problem-based learning model containing ethnomathematics supported by ETHLAF APPS, which is better than applying a direct learning model. This type of research is quantitative, using quasi-experimental methods and a nonequivalent pretest-posttest control group design. The sampling technique uses purposive sampling. This research was carried out in class X of Senior High School. The data collection technique uses tests, and the instrument uses concept understanding test questions. Data analysis includes the normality test, homogeneity test, similarity test, and final data analysis, namely the independent sample t-test. The research results show that the average ability of students to understand concepts when applying the problem-based learning model based on ethnomathematics assisted by ETHLAF APPS is better than when applying the direct learning model. This research concludes that students' ability to understand concepts using the ethnomathematics-based problem-based learning model supported by ETHLAF APPS is better than using direct learning. The ability to understand concepts is the main goal and important factor in learning mathematics.

Confidence helps to see life from the positive side and helps to find new experiences. This self-confidence has not been well embedded in slow learner students. Slow learner students have low self-confidence. One of the reasons for low self-esteem is discrimination and bullying at school. The purpose of this study was to analyze the level of self-confidence of slow learner students. This study uses a quantitative research approach. The research method used is a survey method. The respondents of this study were slow learner students in grade IV who had gone through psychological tests. The number of slow learner students is five students based on psychological tests. Data collection techniques using observation and questionnaires. This study tested the validity of the data by using the credibility test. Testing the credibility of the data is done through triangulation and using reference materials. This study uses data analysis techniques Miles and Huberman models. Qualitative data analysis was carried out by reducing data, presenting data, and drawing conclusions/verification. The result of the research is that the teacher still does not understand the characteristics of the slow learner students. Slow learners feel that the teacher does not care. Slow learners do not understand the material taught by the teacher. Slow learner students tend to be quiet and look down while studying. The self-confidence analysis shows that all students are slow learners in the category of not being confident.

This study aims to see how the information representation and the role of e-news media on bullying cases of students with learning difficulties or called slow learners in e-news media. This research uses qualitative research through content analysis. The object of the research is e-news about bullying cases by two teachers in a school in Medan and bullying cases by several students in a school in Semarang, on detik.com and kompas.com. The results showed that the representation of information about bullying on students with learning difficulties in schools included information about the beginning of viral cases on social media, personal experiences, negative impact on victims of bullying, the results of investigations of various related parties, consequences for perpetrators of bullying, information containing support for victims of bullying, policies and programs to prevent bullying, information containing education for the public, information in order to build awareness and solidarity and action of the anti-bullying movement. These representations of information illustrate that e-news media do not only present news in the sense of reporting a case, but also support information literacy by providing understanding, concern and awareness of bullying cases. Meanwhile, e-news media have played a role in disseminating information, conducting anti-bullying campaigns, creating an open culture in discussing cases of bullying in the public sphere, providing education, building public awareness and solidarity in bullying prevention actions, providing advocacy, intervention and collecting feedback from the public on policies and implementation of the anti-bullying movement. In the end, e-news media is expected to be able to participate in the bullying prevention movement in schools.

The usability of internal quality audit systems plays a crucial role in ensuring the effectiveness of academic governance in higher education institutions. This study evaluates the usability of an internal quality audit system using the System Usability Scale (SUS) framework. The findings reveal a mean SUS score of 72.4, indicating good usability but highlighting key areas for improvement, particularly in navigation, interoperability, and data management workflows. A comparative analysis with previous research shows that while the system performs better than some older academic management systems, it still lags behind general academic information systems. Based on user feedback, recommendations for interface redesign, system integration, and workflow optimization are proposed to enhance overall usability. Future research should focus on user-centered design improvements, AI-driven automation, and broader system interoperability to further refine the effectiveness of quality audit processes in higher education institutions.

Problem-solving skills are essential in improving the creative, critical, and logical thinking skills needed in mathematics learning and daily life. This study aims to examine the effectiveness of problem-based learning (PBL)-assisted ethnomathematics-based Geocube e-module on problem-solving skills. This quantitative research applied a quasi-experimental design. The specific design applied in this research is the non-equivalent pretest-posttest control group design. The research sample consisted of 32 participants, all of whom were students involved in this study. Research instruments included test questions. The researchers analysed the data using a two-sample t-test for independent samples and an N-gain test. The results showed that the application of the PBL learning model assisted by the Geocub e-module based on ethnomathematics effectively improved problem-solving skills. It can be seen that (1) the average mathematical problem-solving skills of students in the experimental class were better than the control class, (2) there is an increase in the average of students' mathematical problem-solving skills after being taught the PBL model assisted by the Geocub e-module based on ethnomathematics. The researchers concluded that the implementation of PBL, assisted with the ethnomathematics-based Geocub e-module, effectively improved the mathematics problem-solving skills of the students.
