This study endeavors to enhance the scientific learning results of sixth graders at SDN Jajar Tunggal III/452 Surabaya by using the Problem Based Learning pedagogical approach with the support of wordwall media, with a focus on global Indonesian cultural heritage materials. Two rounds of classroom action research have been conducted. Class VI-A students from SDN Jajar Tunggal III/452 Surabaya in the 2024–2025 school year were the focus of this investigation.  This study use (1) as its method of data collecting.  Second observation. Recordings, three. Interview. The proportion of classical student learning outcomes that fell into the "very low" category was 32.14% before the cycle began, 67.85% during the first cycle, and 100% during the second cycle. Compared to the first cycle's assessment, the second cycle's outcomes were better. With an average final score of 85.55, the assessment findings for cycle II of classical learning completion attained 100%. The results show that in the 2024–2025 school year, students in class VI–A at SDN Jajar Tunggal III/452 Surabaya may benefit from using the problem-based learning approach with wordwall medium to study world-class Indonesian cultural heritage.

Learning outcomes are a series of skills, knowledge, attitudes and values ​​obtained by students in their thinking process during learning activities. This research aims to improve the learning outcomes of class X-4 students on opportunity material by applying the problem based learning model assisted by wordwall media. To see an increase in learning outcomes, classroom action research was carried out for two cycles using the method of observation and analysis of test results with research instruments in the form of pretest posttest questions in the 2023/2024 academic year. The subjects of this classroom action research were 34 students from class X-4 at SMA Negeri 9 Surabaya. The research results showed a consistent increase in learning outcomes over two cycles in the opportunity material. Before the action was taken there were 18 students who had not reached the KKM and only 16 students had completed it so the percentage of completion was 47.05% with an average learning outcome of 67.76. In the first cycle, the number of students who completed their learning outcomes reaching the KKM increased to 28 with a completion percentage of 82.35% and an average learning outcome of 78.23. In cycle II, the number of students whose learning outcomes achieved the KKM consistently increased so that there were 31 with a completion percentage of 91.17% and an average learning outcome of 89.54.

The problem of this research is that there is still a lack of student activity in participatory learning as well as interaction and collaboration between students in group learning activities. In this research, Classroom Action Research (PTK) was carried out in three meetings. The subjects of this research were 25 class V students of SDN Antasan Besar 7 Banjarmasin. The measure of research success with learning completeness is that 80% of students achieved a KKM score above 80. The results of this research show that at Meeting I to Meeting III there was an increase in the acquisition of learning activities in the application of the learning model, resulting in the "Very Active" criteria at Meeting I, II and III. At Meetings II and III, learning activities increased to almost all very active. Students' critical thinking skills increased to almost all highly skilled at Meetings II and III. At Meetings II and III, students' collaboration skills increased to Almost All Skilled. Meanwhile, completeness of learning outcomes increased again to 100% at Meeting III. From the results of this research, it can be concluded that educators' activities experienced a very significant increase when implementing the PBL model supported by DNGM using Wordwall media and the Dragon Snake game, as well as student activities, critical thinking skills, collaboration skills, and learning outcomes.
