The "1-2-2" model is a simple framework used in various fields, including education and communication. It suggests a structure where one main idea is introduced, followed by two supporting details, and then two examples or applications. This format helps in organizing thoughts clearly and effectively. In practice, the "1-2-2" model can enhance presentations, essays, and discussions. For instance, when discussing climate change, one might start with the main point about its impact, provide two supporting facts, and then illustrate these with two real-world examples, such as rising sea levels and extreme weather events.
