1. Summarize the main points: It should reiterate the key ideas and arguments presented in the essay, without introducing any new information. Think of it as a concise recap of what the reader has learned.
2. Provide a final thought or insight: This doesn't have to be a dramatic revelation, but it should offer the reader something to consider beyond the basic explanation. It could be a reflection on the significance of the topic, a connection to a broader context, or a call to action related to the subject.
3. Offer a sense of closure: The conclusion should leave the reader with a feeling of completeness, leaving no loose ends or unanswered questions.
4. Leave a lasting impression: It should be engaging and memorable, reinforcing the essay's overall message and leaving the reader with a clear understanding of the topic.
Avoid these common mistakes:
* Introducing new information: The conclusion is not the place to introduce new arguments or evidence.
* Being repetitive: While summarizing main points, avoid simply repeating the introduction word for word.
* Using overly informal language: Maintain the essay's academic tone.
* Ending with a question mark: While questions can be used effectively, they should be carefully considered and not used to avoid a clear statement.
In essence, the conclusion of an explanatory essay should leave the reader feeling informed, engaged, and satisfied.
