The purpose of this action research was to enable university students to learn about children's rights with the scenarios developed based on the problem-based learning (PBL) approach. In this context, three scenarios related to daily life have been developed on the right to participate, the right to education, the right to rest, leisure, play, and participate in cultural and artistic life and the legal basis of these rights. The study group consists of students studying in the Child Development associate degree program of a state university in Türkiye. Pre-post application questions, structured interview form, and researcher diary were used as data collection tools. The obtained data were subjected to content analysis with the NVivo qualitative analysis program. As a result of the analysis, it was determined that the students' knowledge about children's rights increased, they could make more accurate and explanatory definitions, and they could explain national and international legal bases. In addition, students expressed positive opinions about the scenarios developed for the application.
