The aim of the study is to design Nexus curriculum model for the major group of humanities. For higher education, it is of great importance to understand how research can be integrated into the curriculum to enhance student learning and enhance capabilities. The curriculum can act as a bridge between the macro-level of decision-making and its micro-level. In the present study, a qualitative approach and a research synthesis method were used to explain the curriculum elements. The statistical population included upstream documents, books, articles, dissertations, and related theses. After content analysis and axial and selective coding of the data obtained from document review, the initial characteristics of the nexus curriculum elements were extracted and then interviews were conducted with relevant experts and professors, and their opinions were used to modify the proposed model,. For reliability, two evaluators recoded the findings. In order to confirm the reliability, In this model, 52 axial codes and 11 selective codes were identified. Such as accepting the temporary nature of knowledge, promoting a national research culture, selecting interdisciplinary contents, participatory and project-based teaching methods, student-based activities, employing research groups, critiquing or conducting real research, culminating research in final semesters, and the need for rich and supportive environment, were identified. In summary, it can be said that research enhances teaching by keeping the content up-to-date and engaging, and the research-teaching linkage curriculum enriches education by making research an integral part of learning.
