Today’s era is known as the era of cyberspace, which experts describe as a double-edged sword. On one hand, the significant influence of cyberspace on all aspects of social life is undeniable, and on the other hand, its harms and threats have also drawn the attention of experts. The aim of the present research is to propose a content model for parental education to prevent the harm of cyberspace among students. This research employs a qualitative method and is applied in nature. The statistical population of this research consists of specialists in the field of cyberspace, with a sample of 11 experts selected using theoretical saturation and convenience sampling. The data collection methods include a review of the literature and semi-structured interviews with experts and specialists. To validate the findings, expert opinions were used, and to ensure reliability, the coefficient of agreement between coders was applied. Data analysis was performed using coding methods. The findings indicated that the content of parental education for preventing cyberspace harm should encompass three components: knowledge (benefits of cyberspace, understanding cyberspace harms, and enhancing parental awareness), attitudes, and skills (technological skills, parenting, and life skills). It can be concluded that by developing their knowledge, skills, and attitudes toward cyberspace, parents can reduce the risks associated with cyberspace for their children to some extent.
