The Future of Jobs Report (World Economic Forum, 2. states that CPS is a key skill required in the world of work. In addition. CPS is also very important for children of concrete age in developing critical and analytical thinking skills from an early age because at this stage of development, children learn through direct, concrete, and contextual experiences. CPS skills not only help students understand abstract concepts but also support them in solving problems in real-life situations. However, facts show that the CPS abilities of students in Indonesia are still low. A similar condition was found in Bone Regency, especially at the elementary school level, with an average mathematics score of only 46. (Puspendik, 2. These results are also reinforced by the Minimum Competency Assessment Andi Rosdaliani. The Songkok Recca. (AKM), where the majority of students showed achievements below the standard (Assidiq. Agustin and Ripaldi, 2. This is also evidenced by the 2022 PISA results, which show that the average mathematics score of Indonesian students is only 366, far below the OECD average Observations and interviews at several elementary schools in Bone Regency show that nearly 60% of students are unable to identify and determine number patterns, especially in This finding is in line with the research by Indriyani and Muthi . that many students have difficulty understanding multiplication material. In fact, some students feel stressed when trying to solve multiplication problems (Nurazani et al. , 2. A number of students choose to skip math class because they are afraid and experience high anxiety (Sugiarti and Kusmayanti, 2. This condition indicates the need for alternative solutions in the form of learning models that enable students to learn in a meaningful and contextual way, so that they can increase their motivation to learn through learning that is integrated with everyday life, while introducing mathematics and local culture to students. One approach that has the potential to support the creation of meaningful, contextual, and culture-based learning is Ethno-STEAM (Science. Technology. Engineering. Art, and Mathematic. This is in line with Vygotsky's social constructivism theory, which emphasizes the importance of social and cultural interaction in learning (Asfar. Asfar, & Nurannisa, 2. One of the famous cultural icons in Bone Regency is the Songkok Recca, which is rich in mathematics in every pattern of its trajectory and has great potential to become a learning medium to enrich students' understanding of mathematical concepts. The Songkok Recca, which is a cultural symbol that not only serves as a marker of Bugis identity but also reflects life values such as perseverance, creativity, and cooperation (Aryani, 2. However, the younger generation today is unfamiliar with the philosophy of the Songkok Recca. This is due to cultural shifts caused by modernization, coupled with the lack of integration of local culture into the learning process. As a result, education as a means of cultural inheritance does not function optimally. Therefore, this research aims to develop a mathematics learning model using the songkok recca as a teaching aid to improve students' Complex Problem Solving (CPS) skills while preserving the Bugis Bone culture from an early age. In addition to culture, technology plays an important role as an interactive learning medium in supporting the Ethno-STEAM approach. One platform that can be integrated into learning is Live Worksheet. Live Worksheet allows students to work in groups, divide tasks, and solve problems in a structured manner (Sinaga, 2. This platform can be used to design questions based on the Songkok Recca diagonal pattern . over - 2 unde. riase na 2 riaw. , which guides students to identify problems, evaluate information, and find solutions, thereby supporting the development of Complex Problem Solving (CPS) skills. Research by Mardhatilah. Zaini, and Kaspul . states that the use of digital applications in learning is very effective in improving students' analytical, evaluative, and creative skills. The integration of Live Worksheet into the Songkok Recca-based Etno-STEAM model enables the creation of a concrete, contextual, and relevant learning experience in line with the current curriculum's learning objectives, namely the development of reasoning, critical thinking, and contextual problem-solving competencies. 114 | International Conference on Global Innovations in Education. Science, and Technology Volume 1. September 2025, pp. This research aims to develop an Etno-STEAM Songkok Recca-based learning model assisted by Live Worksheet as an interactive digital media. Rifai . explains that in the application of STEAM learning, integration with digital media can facilitate learning reflection to be in line with learning objectives. The integration of Live Worksheet into the Etno-STEAM Songkok Recca learning model is expected to support the development of students' Complex Problem Solving (CPS) skills while creating joyful, mindful, and meaningful learning. This is in line with the research by Sinaga et al. , which states that the use of digital media such as Android applications is effective in improving CPS, which is key to 21st-century technology-based mathematics learning. Nurannisa et al. also emphasize that in addition to technology integration, incorporating local wisdom rich in values into education can bridge traditional knowledge with contemporary knowledge. Similar support is shown by research by Enjelina. Damayanti, and Dwiyanto . , which concludes that the integration of culture in mathematics learning can increase learning motivation while preserving local culture. In addition, local wisdombased mathematics learning provides opportunities for students to understand concepts in depth by utilizing local culture (Asfar. Asfar, and Nurannisa, 2. However, to date, no research has been found that examines the multiplication pattern of Songkok Recca. The majority of research only discusses the cultural values of Songkok Recca in Bone Regency (Sumantri and Faisal, 2. In fact, the Songkok Recca pattern is rich in mathematical meaning, especially the multiplication pattern, so it has the potential as a medium for mathematics Therefore, the novelty of this research lies in the development of a valid, practical, and effective Songkok Recca Ethno-STEAM learning model assisted by Live Worksheets that supports the CPS of children of a concrete age while contributing to the preservation of local culture by integrating the philosophical values of Songkok Recca into learning. This research also supports the achievement of Sustainable Development Goals (SDG. point 4 . uality educatio. Asta Cita point 8 . armonizing life with cultur. , and is in line with the thematic PKM point 6 . trengthening education, science, and technolog.

However, after implementing the Songkok Recca Ethno-STEAM Learning Model, the average posttest score of the experimental class increased sharply to 95. 20, which was much higher than that of the control class . This increase was also evident in the minimum and maximum scores, where the minimum score of the experimental class rose from 00 to 88. 00, while the control class only rose from 32. 00 to 38. 00 at its lowest score. The standard deviation in the experimental class decreased significantly from 9. 80 to 3. indicating that the students' learning outcomes were more evenly distributed after the implementation of the learning model.

Comparison of N-Gain Scores between the Control Class and the Experimental Class Based on the results of data analysis, the improvement in students' Complex Problem Solving (CPS) abilities can be seen through a comparison of gain scores and N-Gain Scores between the control class and the experimental class. In the control class, the gain score obtained from the difference between the posttest and pretest scores was 17. 00 with an N-Gain percentage of 38%. This percentage is in the low . category according to Hake's . criteria, which means that the problem-based learning model used in the control class did not have a significant impact on improving students' CPS abilities. Conversely, in the experimental class that received treatment using the Etno-STEAM Songkok Recca learning model, the gain score obtained was 29. 24 with an N-Gain percentage of 68. 6%, which is in the moderate . These results show that the application of the Etno-STEAM Songkok Recca model was able to provide greater improvement in CPS skills compared to conventional learning. The difference in the percentage increase between the control class and the experimental class indicates that the use of a local wisdom-based learning model (Songkok Recc. combined with the STEAM approach contributes significantly to learning outcomes. The characteristics Andi Rosdaliani. The Songkok Recca. of the model, which integrates elements of ethnopedagogy, creative processes, and real problem-solving activities based on local culture, make learning more contextual, interesting, and meaningful for students. Therefore, these findings reinforce the evidence that the development of the Songkok Recca Ethno-STEAM learning model is not only theoretically valid and practical to use, but also effective in improving the CPS skills of elementary school students, especially in grade IV at the research location.
