Abstract The attitude of cooperation is very important to be instilled in students so that students can easily socialize wherever they are. The attitude of cooperation is a self-aware attitude from each individual to help ease the burden on other individuals. The cooperation attitude has the characteristics of mutual care, cooperation, democracy, discussion, mutual help, habituation of consensus deliberation, empathy, solidarity, loyal friends, and volunteerism. In group learning after the Covid-19 pandemic, the students' cooperation attitude began to weaken. Several indicators of a weakened cooperation attitude were collaboration, caring, and sharing. According to the teacher, the weakening of this cooperation attitude is because students are used to learning independently at home, so students feel they can do their work without the help of their friends. Thus, this research aims to show the difference in the attitude of cooperation between those who use the project-based learning model and the conventional learning model of elementary school students. The data in this study were obtained from the results of the students' post-response which were analyzed using an independent sample t-test. The results of the post-response show that there is a very significant difference in the attitude of cooperation between those who use the project-based learning model and those who use conventional learning models of elementary school students. This difference can be seen from the post-response results of the experimental class which applies the project-based learning model which is higher than the control class which applies the conventional learning model. Keywords: project based learning model, mutual cooperation attitude, elementary school Abstrak Sikap gotong royong sangat penting ditanamkan didalam diri siswa agar siswa dapat mudah bersosialisasi dimanapun mereka berada.

Mathematics is studied in Indonesia at all school levels because it is able to train students' problem-solving skills and meet practical demands. Teachers and students still face a lot of challenges in putting these strategies into practice, though. The fact that the course material did not adhere to the approaches and models that attracted and engaged students was one of the problems. The 2013 curriculum aims to develop productive, inventive, creative, and character-defining learners by integrating the development of attitudes, abilities, and knowledge. The mind-mapping learning paradigm has the power to inspire pupils, excite them, and pique their interest in the content they are studying. In order to create educational materials employing a mind mapping methodology with a scientific approach, developmental research is also required. A stage known as implementation is necessary for the proper production and distribution of the development material. This study concentrates on the implementation phase to evaluate the usefulness and potency of the information. In one of Kupang's upper secondary schools, the eighth grade saw the implementation of instructional materials. Based on the outcomes of the data analysis, it was determined that each meeting's criteria for teacher and student learning activity fell into the "good" and "very good" categories and satisfied requirements for practicality. According to the post-test findings, 76% of the students were deemed successful. Thus, it may be said that the instructional materials created are efectively.
