The current education system is facing a crucial dilemma: the intensifying focus on cognitive achievement amidst the specific challenges faced by Generation Z. Junior high school students aged 12–15, who are digital natives, are at risk of reduced social interaction and mental health issues due to high screen time. Addressing this urgency, this study aims to describe the strategic role of dance arts education in shaping character and creativity, and to identify implementation solutions at SMP Negeri 1 Wonogiri. This descriptive qualitative study utilized 8 students active in dance as primary subjects, with data collected through observation, interviews, and documentation. The findings indicate that dance arts, through an embodied learning approach based on physical movement, is highly effective in cultivating character. Values such as discipline, which is transferred from the punctuality required in practice to general school life , collective responsibility , and self-confidence that overcomes social awkwardness, grew significantly. Furthermore, dance reinforces authentic cooperation and cultural appreciation. In terms of creativity, the activity encourages movement exploration, improvisation, and creative problem-solving. Psychologically, dance practice functions as a positive coping mechanism that effectively lowers adolescent stress levels. Although constraints exist, such as limited instructional time (80 minutes per week) , adaptive solutions like strengthening extracurricular activities and the peer tutoring system are being implemented. This research concludes that dance arts education is an essential and strategic medium for developing holistic competencies, including the 4Cs (Critical Thinking, Creativity, Collaboration, and Communication) and the Profil Pelajar Pancasila.

The use of technological resources, especially the internet, has a very important role in supporting the effectiveness of the implementation of the flipped classroom model. Through internet access, students can prepare before face-to-face learning by watching learning videos, reading materials, or doing exercises independently. This allows the classroom teaching and learning process to be more interactive, where face-to-face time can be focused on discussion, problem-solving, and application of concepts. Based on survey data collected from students of SMK Dewata Bali Denpasar, it is known that optimal use of the internet helps increase students' understanding and interest in learning science subjects. However, as time went by, it was found that some of the material was still difficult for students to understand and remember. Therefore, educators need to choose the learning platform that is most effective in supporting the implementation of this model. Using the ELECTRE (Elimination and Choice Expressing Reality) method, this study assessed various platforms such as features, price, ease of use, and user survey results. The results show that Google Classroom is the most suitable and efficient platform to support reverse learning because of its ability to integrate various learning media, ease of access, and support for interaction between teachers and students.

Learning quadratic functions in high school still faces various challenges, primarily due to the abstract nature of the concepts, which require students to have strong analytical thinking skills. These difficulties often result in low student understanding of the relationship between quadratic equations and parabola graphs, as well as limitations in applying these concepts to mathematical problem-solving. GeoGebra, as a technology-based learning tool, offers interactive visualizations that allow students to observe the real-time changes in the shape of a parabola when the coefficients in a quadratic equation are modified. A literature review of recent studies reveals that the use of GeoGebra significantly enhances conceptual understanding, mathematical representation skills, and student motivation. Its effectiveness further increases when combined with appropriate teaching strategies, such as the 5E model (Engage, Explore, Explain, Elaborate, Evaluate), which encourages active involvement and concept exploration by students. However, several challenges remain, including limited access to devices, teachers’ readiness to utilize technology, and suboptimal infrastructure support. Therefore, the integration of GeoGebra into quadratic function learning requires careful planning, teacher training, and adequate facility support to maximize its benefits and improve the overall quality of mathematics education.

Mathematical problem-solving skills are essential for students to face academic challenges and real-life situations. However, the 2022 PISA results and preliminary observations at MTs Negeri 1 Kota Semarang indicated that these skills were still low, particularly in the topic of Linear Equations in Two Variables (SPLDV). This study aimed to develop a flipbook-based teaching material integrated with differentiated learning by considering students’ learning styles (visual, auditory, and kinesthetic), and to examine its feasibility, readability, effectiveness, and students’ responses. This research employed the Research and Development (R&D) method using Borg & Gall’s model with eighth-grade students of MTs Negeri 1 Kota Semarang as the subjects. Data were collected through observation, interviews, questionnaires, documentation, and pretest-posttest. Data analysis was conducted qualitatively (expert and practitioner validation) and quantitatively (feasibility and readability tests, effectiveness tests using one-sample t-test, independent t-test, paired t-test, N-Gain, and individual mastery test using Actual Mastery Threshold/BTA). The findings showed that the flipbook was highly feasible (91.20%) and very readable (92.10%). The developed teaching module received very good validation (88.75%), while the test instrument demonstrated good to very good validity, reliability, difficulty level, and discrimination power. The experimental class average score increased from 49.12 (pretest) to 67.35 (posttest), while the control class rose from 48.82 to 53.53. Statistical tests revealed significant differences (p < 0.001), with an N-Gain score of 0.73 (high category). In addition, individual mastery was achieved based on BTA, and classical mastery was met since more than 75% of students scored above the minimum criteria. Thus, the developed flipbook-based differentiated learning material was feasible, comprehensible, effective in improving mathematical problem-solving skills, and received very positive responses from students.

This study investigates the use of experimental statistical analysis as an instructional approach to enhance students’ understanding of variable relationships in science learning. Many students tend to memorize experimental results without comprehending the underlying relationships between variables, resulting in limited analytical reasoning and superficial understanding. To address this issue, the present study explores how integrating basic statistical tools-such as mean, correlation, and regression-into experimental activities can strengthen conceptual comprehension, analytical reasoning, and scientific literacy. Grounded in constructivist and inquiry-based learning frameworks, the research emphasizes active engagement, where students participate in data collection, analysis, and interpretation to draw evidence-based conclusions. The study employed a quasi-experimental design involving science students divided into experimental and control groups. Both groups conducted similar laboratory experiments, but only the experimental group received explicit instruction in statistical analysis. Data were collected through pre-tests and post-tests to measure changes in students’ understanding of variable relationships. The results indicated a 25% improvement in the experimental group’s comprehension and reasoning ability compared to the control group. Students who applied statistical analysis demonstrated greater proficiency in interpreting data, identifying causal patterns, and connecting theoretical knowledge to experimental findings. In contrast, students taught through traditional narrative-based instruction showed minimal gains and relied heavily on memorization. The findings highlight the effectiveness of integrating statistical reasoning in promoting critical thinking, problem-solving, and scientific reasoning skills.

This study was motivated by the need to improve the quality of Islamic Religious Education (IRE) learning so that it does not only focus on delivering material but also encourages students to actively build understanding through higher-order thinking processes. Traditional teacher-centered learning tends to limit students' analytical, evaluative, and creative abilities. Therefore, this study aims to analyze the use of Active Learning in IRE and its relationship with the development of Higher Order Thinking Skills (HOTS). The method used was library research with a Systematic Literature Review (SLR) approach, which involved identifying, selecting, and synthesizing various relevant literature from the last ten years. The results of the study showed that Active Learning was implemented through various strategies such as problem-based learning, project-based learning, think-pair-share, the use of digital technology, and collaborative discussions. These strategies shift the focus of learning from the teacher to the students so that they can construct knowledge through dialogue, reflection, and problem solving. The findings also show that this approach has a direct influence on the development of HOTS, especially the ability to analyze religious issues, evaluate arguments based on arguments, and create contextual solutions in learning situations. In addition to improving cognitive abilities, Active Learning has an impact on increasing learning motivation, courage to ask questions, active involvement, and the quality of students' social interactions. The implications of this study confirm that PAI learning needs to integrate Active Learning strategies.
