Students' difficulties in understanding algebraic operations, particularly in translating contextual problems into symbolic expressions, highlight the need for instructional media that support visualisation, structured scaffolding, and active engagement. This study aimed to develop and evaluate Articulate Storyline-based interactive media for learning algebraic operations using the ADDIE model (analysis, design, development, implementation, and evaluation). Data were collected through expert validation sheets, student practicality questionnaires, and post-test assessments, and analysed using descriptive statistical techniques (mean scores and percentage distributions). The product was implemented in three stages: one-to-one testing (3 students), small-group testing (8 students), and a field trial involving 18 seventh-grade students. Expert validation indicated that the media was highly valid across content accuracy, contextual suitability, presentation quality, and instructional design. Practical results showed positive student responses regarding usability and engagement. The post-test mean score was 82, and all students achieved medium to very high performance, indicating potential improvement in conceptual understanding. This study contributes to mathematics education by providing an empirically validated multimedia design that integrates contextual animation, step-by-step symbolic visualisation, and interactive feedback to address abstraction challenges in algebra learning.

This study aims to describe the intensity of TikTok application use and analyze its influence on the morals of ninth-grade students toward teachers at SMPN 1 Talang Kelapa. The background of this research stems from the increasing use of TikTok among teenagers, which has the potential to affect behavior and moral values in interactions with teachers. The study uses a quantitative approach with a descriptive-correlational method. The sample consists of 60 students selected through purposive sampling techniques. Data were collected through a Likert-scale questionnaire that had been tested for validity and reliability, then analyzed using Pearson correlation and simple linear regression with the help of SPSS version 26. The results show that the intensity of TikTok use is categorized as high (mean = 78.45), while students’ morals toward teachers are categorized as fairly good (mean = 68.12). The correlation test resulted in r = -0.612 (p = 0.000), indicating a significant negative relationship between the two variables. The regression results show R² = 0.375, meaning that TikTok usage influences 37.5% of students’ morals. Thus, the higher the intensity of TikTok use, the lower the students’ morals toward teachers. Cooperation among teachers, parents, and the school is needed in character development and digital literacy so that social media can be used positively.

This study aims to develop exploration activities for flat shapes (triangles and quadrilaterals) using GeoGebra Classroom, designed to improve conceptual understanding among seventh-grade students. This research is motivated by the low understanding of mathematical concepts, where students often rely on procedural memorization. The study uses the Research and Development (R&D) approach with the 4D model (Define, Design, Develop, Disseminate), focusing on the Develop phase. Data collection instruments include expert validation sheets (content and media), field observation guidelines, and conceptual understanding tests. Data analysis is conducted using both qualitative and quantitative descriptive methods to assess the feasibility of the product. These exploration activities were intentionally designed without the instant presentation of formulas to encourage students to independently construct geometric properties through GeoGebra's dragging feature. The expected outcome of this research is the creation of a valid and practical learning tool that helps students visualize and understand geometric concepts meaningfully

In today's digital era, statistical literacy has become a crucial competence for individuals to understand and interpret data-based information presented in tables, graphs, and diagrams. Although data representation is a fundamental part of the Junior High School (SMP) mathematics curriculum, reality in the field indicates that many students still face obstacles in critically interpreting data. Student understanding is often limited to reading data explicitly, lacking the ability to perform deeper evaluation or analysis. This study aims to analyze the level of Junior High School students' understanding of statistical data representation, identify the types of difficulties students face in interpreting data visualizations, and explore the various factors influencing their level of comprehension. In order to give a comprehensive summary of the respondents' situations, this study utilized a descriptive methodology with a qualitative approach. During the 2025–2026 school year, researchers at SMP Fitra Abdi Palembang collected data. Students in the high, medium, and low understanding groups were included in the subject selection process through the use of a purposive sampling technique. To begin, we used a questionnaire to collect basic information on students' perspectives; to round up our data, we used semi-structured interviews to confirm students' reasoning behind their responses. Indicators of mathematical competence, such as the capacity to categorize objects, choose operational processes, and apply algorithms for solving problems, were considered in the data analysis procedures that comprised data reduction, data presentation, and drawing conclusions. This study aims to assess students' statistical literacy in a comprehensive way. By doing so, we can help junior high school teachers enhance their data analysis skills through the development of more contextual and effective learning methodologies.
