Visuals, hands-on objects, and realia, although important, can lead to problematic classroom behaviours if teachers are not prepared to react to them.
Objects of realia, due to their diverse and compound nature, pose unique preservation challenges for libraries and archives.
A teacher of a foreign language often employs realia to strengthen students' associations between words for everyday objects and the objects themselves.
It is noteworthy for its detailed index, thorough cross-references, extensive footnotes with maps and diagrams, and research on realia, flora, fauna, and geography.
One must also consider how the element of realia relates to the source culture in terms of importance and familiarity.
Some libraries prize their realia, actively preserving and exhibiting it while others simply keep it out of light and hope for the best.
Often, realia are seen as a nuisance, difficult not only to catalog, but to care for.
Unlike books, which are mostly cellulose (paper, boards, natural fibers) and occasionally leather, realia are often the sum of many parts.
