Aim: Religion, and, in general, culture are among the most important components of national identity worldwide. Islam is considered one of the primary criteria for the national identity of Iranians. Therefore, strengthening national identity is somewhat linked to reinforcing religious foundations. Among these religious foundations, beliefs serve as the underlying base, and within the principles of belief, monotheism is regarded as the most important element. This article aims to identify the requirements and methods for teaching monotheism to adolescents through edutainment and television programs to enhance their national identity. Methods: Part of the research related to the foundational issues was conducted using documentary and library methods, while the upper-level research, due to a lack of library resources and the novelty of the concept of edutainment in our academic literature, utilized in-depth interviews with experts and specialists. In-depth and targeted interviews were conducted with specialized experts. After conducting the interviews and going through the stages of recording and documentation, the desired data was obtained Findings: In our religious and national culture, numerous uses have been made of this strategy. Since the concept of monotheism is the highest element among Islamic teachings and exists like a soul within the body of all Islamic regulations, it is essential to avoid oversimplifying its education. Shallowing this concept is harmful, and care must be taken to preserve it. Balancing entertainment and education, as well as accurately and correctly understanding today's youth, are also essential requirements in this matter.
