<![CDATA[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.
