Philosophy for children (P4C) has been implemented worldwide. P4C has been researched empirically in order to evaluate its effectiveness and address the current lack of a systemic literature review of research on P4C. Therefore, this SLR study aims to identify how P4C positively affects aspects other than students' thinking and the challenges that teachers and students face in implementing the program. The methodology and writing method used was PRISMA (preferred reporting items for systematic review and meta-analysis). Articles and materials related to the topic were located primarily using two databases, Web of Science and Scopus. Using thematic analysis, this SLR derived five main themes, namely (1) higher-order thinking skills (HOTS), (2) safe environments, (3) civilized students, (4) democracy in discussion, and (5) the culture of thinking in the classroom. There are also challenges faced by teachers and students.
Keywords: challenges; higher order thinking skills (HOTS); non-cognitive; philosophy for children (P4C); the community of inquiry (COI).
