The document summarizes a presentation given at the GLoCALL 2013 conference titled "Explicit vocabulary learning with multimedia glosses". The presentation examined whether visual annotations like images and animations can enhance second language text comprehension. It discussed previous research finding multimedia glosses are effective for vocabulary learning. The presenter's study compared the effectiveness of pictorial versus animated schematic images defining spatial prepositions. Results showed no significant differences in comprehension or production between the visual gloss types. The presentation concluded other factors may influence effectiveness and multimedia glosses need to be used appropriately.
