What characterizes referential teaching?

Referential teaching is characterized by a focus on direct, specific communication rather than broader or social interactions. The correct answer emphasizes requirements for single word answers while using fringe vocabulary, which means it involves teaching that seeks direct and definite responses, often limiting the complexity of communication expected from the learner. This method is typically used to enhance specificity in language use and comprehension.

Using core vocabulary in conversations, asking open-ended questions, or fostering social interactions does not align with the referential teaching method's emphasis on concise and clear communication. Rather than encouraging a flow of conversation or the exploration of ideas, referential teaching is more about ensuring that the communication is structured and focused, aligning with the characteristics outlined in the correct answer.
