Here's why:
* Shared understanding: Peers are likely to have read the same text and share a common understanding of the material. This allows for a more conversational and less formal tone.
* Personal connection: Informal writing encourages personal reflections and opinions, fostering a sense of connection and shared experience among peers.
* Accessibility: An informal style can feel more approachable and less intimidating, making it easier for peers to engage with the response.
* Emphasis on discussion: Informal writing often encourages open dialogue and debate, promoting a more collaborative learning environment.
However, it's important to note:
* Context is key: The formality of the writing style should always be appropriate for the specific assignment and audience.
* Professionalism is important: While informal, the writing should still be clear, concise, and respectful.
In general, while an informal style can work well for peer-to-peer responses, it's best to err on the side of caution and maintain a degree of formality for any academic writing, particularly when addressing a wider audience or instructors.
