Meaning Equivalence Reusable Learning Object (MERLO)

MERLO is a multi-dimensional database that allows the sorting and mapping of important concepts through multi-semiotic representations in multiple sign systems, including: exemplary target statements of particular conceptual situations, and relevant other statements.Each node of MERLO database is an item family that includes five statements: one Target Statement (TS) that describes a conceptual situation and encodes different features of an important concept; and 4 other statements that are sorted by two sorting criteria: • shared equivalence-of-meaning with TS• shared surface similarity with TS
