Only little is known about the epistemic beliefs of elementary school children. In this exploratory study, semistructured interviews were used to solicit epistemic beliefs of fourth grade students (n = 98; mean age = 10 years, 4 months) about the verification of second-hand knowledge. The data analysis was based on the Qualitative Content Analysis (Mayring, 2001), supported with Atlas.ti software, and yielded a high in interrater reliability (Cohen, 1960; κ = 0.94). In fourth grade students, a complex system of beliefs was identified about strategies of second-hand knowledge verification (independent strategies n = 8; dependent strategies n = 3), knowledge sources (human sources n = 4; non-human n = 4), and different source selection criteria (n = 8). Moreover, some students (n = 10) mentioned a cognitive process that they would employ to identify the best possible sources for the processes of knowledge verification, similar to following a decision tree. The discussion explores meaning of the identified multi-faceted and partially meta-cognitive nature of belief systems for the conceptualization of the developmental, dimensional, and situational frameworks as they exist currently.Keywords: Epistemic belief, personal epistemology, knowledge justification, Knowledge sources, higher-order thinking, children.
Highlights: An exploratory study with Fourth Grade Students (n = 98) using semi-structured interviews. Identified complex epistemic belief systems based on their diversity and interconnectedness. Students had epistemic beliefs about strategies of second-hand knowledge verification (n = 11), knowledge sources (n = 8), and different source selection criteria (n = 8). Some students expressed thinking process about source selection that can be conceptually located at a higherorder of thinking. The complexity of epistemic belief systems challenges the explanatory power of existing frameworks.
