This study discusses the effect of the Problem Based Learning model on students' mathematical creative thinking skills on cube and cuboid material. The research was carried out using an experimental method involving students of SMP Negeri 3 Limboto Barat as research subjects. The research design used is Post Test Only Control Design. Sampling was carried out using the Simple Random Sampling technique. Measuring mathematical creative thinking ability is done using a test instrument that has met the requirements of item validity and instrument reliability requirements. The results showed that applying the Problem-Based Learning model in learning significantly influenced students' creative thinking skills on cube and cuboid material. This can be seen from students' mathematical creative thinking ability in learning using the Problem-Based Learning model, which is higher than students' mathematical creative thinking ability in direct learning.

The use of learning media is still limited, making students tend to be more passive during the learning process. At SMA Negeri 1 Suwawa, the learning process predominantly uses textbooks, whiteboards, LKPD, and sometimes PowerPoint. These limitations make it difficult for students to understand the material, including mathematics lessons on the material of the System of Linear Equations of Three Variables (SPLTV) which requires image visualization. With the existing problems, research was conducted by utilizing technology which aims to develop mathematics learning media using the Sparkol VideoScribe application on SPLTV material which was carried out involving 20 class X students at SMA Negeri 1 Suwawa in June. This type of research uses the Research and Development (R&D) method using the four-D development model, namely Define, Design, Develop and Disseminate. Data analysis was carried out based on expert assessments, teachers, and student responses using a Likert scale. The development assessment was carried out based on the results of three media validators as well as learning materials and obtained validation results of 77% for media and 82% for materials with criteria worth using. The results of teacher and student responses obtained an average total percentage of 98% and 85% respectively which indicates that the media used meets practical criteria. For further research, it can develop learning media that attract more students' attention in learning activities and increase the activeness of students in learning activities, especially math lessons on SPLTV material.

In the era of globalization, marked by the rapid development of technology, various innovations continue to emerge, including in the education sector. The application of digital transformation in education involves the use of information and communication technology to impact the improvement of learning quality, expand access to learning resources, and create a more interactive and collaborative learning environment. Thus, the education sector has become one of the most responsive fields to technological advancements. This study developed a learning media in the form of comics, named "Komlabil," using i-Spring Suite software on the material of numerical patterns. This media was designed following the PLOMP development model which includes five main stages: Preliminary Investigation, Design, Realization/Construction, Test, Evaluation and Revision, and Implementation. The research subjects were 27 eighth-grade students at SMP Negeri 1 Bulawa. This study revealed that digital comic media has been declared valid and practical. Through evaluation by media and material expert validators, an average score of 3.27 was obtained from the media expert evaluation and 3.34 from the material expert, both of which fall into the valid category. This indicates that the developed digital comics meet the expected quality standards, both in design and material content, making it suitable to be used as a supporting tool in learning. The percentage of student and teacher responses obtained 92.37% with a strongly positive category and 89% with a practical category. Based on these findings, the developed learning media is considered suitable to be used in teaching and learning activities because it meets the predetermined criteria of validity and practicality. Thus, this learning media not only meets rigorous academic standards but also contributes significantly to improving the quality of the learning process.

Innovation in interactive learning media is essential to improve the effectiveness of statistics instruction at the junior high school level. This study aimed to develop interactive learning media based on WPS Office to support Statistics learning for eighth-grade junior high school students. The research employed the ADDIE development model, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The media was designed using WPS Presentation and Canva, and then converted into an Android application using Website 2 APK Builder Pro. Validation was conducted by media and subject experts; practicality was assessed by teachers and students. Validation results showed very high feasibility, with an average score of 94.32% from media experts and 95.37% from subject experts. Practicality testing yielded scores of 95.33% from teachers and 93.42% from students, indicating that the media is highly practical and engaging. The developed media is valid, practical, and relevant for supporting contextual and interactive digital learning. It has potential to improve students' conceptual understanding of statistics and their digital literacy.

This study investigates the impact of the cooperative learning model Numbered Heads Together (NHT) combined with interactive learning media on the mathematical problem-solving ability of eighth-grade students. The research aims to address the prevalent low levels of problem-solving competence among students by implementing an innovative student-centered learning approach. Using a quasi-experimental design with a post-test only control group, this study involved two classes selected through random sampling at SMP Negeri 1 Kwandang, with 30 students in each group. The experimental group received the NHT learning model supported by interactive media, while the control group was taught using a direct instruction method with the same media. Data were collected through validated problem-solving tests, analyzed using independent sample t-tests, normality and homogeneity tests, and effect size calculations. The results demonstrated a significant difference between the two groups, with the experimental group achieving higher problem-solving scores (mean score of 32.6 versus 27.9) and a high effect size (Cohen's d = 0.9032). These findings suggest that integrating NHT with interactive learning media effectively enhances students' mathematical problem-solving skills by fostering active engagement, collaboration, and conceptual understanding. The study highlights the importance of adopting interactive, student-centered learning models to improve mathematics education outcomes.
