In the context of the TOEFL® speaking section, Discourse Coherence refers your ability to express your ideas in a clear and logical manner. This means that you should use cohesive devices, such as pronouns and conjunctions, to connect your ideas and create a clear flow of thought.
Additionally, you should organize your ideas into a logical structure that is easy for the listener to follow. A speaker with good Discourse Coherence will be able to effectively communicate their ideas and make their speech easy to understand.
