Background and purpose: Computer literacy is of great importance in the modern world. It means the ability to use computers and understand the concepts related to them, as well as a basic skill in most job and application fields. The current research aim to design a model for developing computer literacy among elementary school students based on grounded theory. Method: To present this model and obtain data suitable for the study field under study, the qualitative method of the theory arising from the data or foundation data was used. The participants in the present study, which was conducted in Yazd province were experts with master's degree and doctorate in technology, 20 of them were selected by theoretical sampling to conduct in-depth interviews, and the interviews continued until theoretical saturation was reached. Validity and reliability of findings were checked using stability index and reproducibility index. Open, axial and selective coding was used to analyze the qualitative data. Findings:The results show that 703 primary conceptual propositions with 66 sub-categories and 27 main categories in the form of 6 dimensions of the paradigm model include: Causal causes (family, school, group interactions, teacher, content, facilities, learning opportunity), main phenomenon (developing computer literacy), strategy (teaching, monitoring, planning, motivation, learning assignments, learning reinforcement), contextual conditions (literacy, teaching methods, technology), environmental conditions (economic conditions, cultural conditions, social conditions, political conditions) and consequences (interest in learning, optimal use of resources, increasing skills, increasing awareness, creating opportunities, self-efficacy, facilitating communication), were identified.Conclusion: The integration of categories based on the relationships between them, around the development of computer literacy, forms a paradigm model that reflects the model of computer literacy development of elementary school students. As a result, developing this skill can help students in daily tasks, studies and even career issues.
