Propositions are when you take a whole sentence or idea and you put it into a simple idea unit without keeping the idea in a correct sentence structure. For example: The girl is pretty. (PRETTY, GIRL).
Well, I think they are five types of text representation. Through the reading, I was only able to identify five different ways to represent text.
1. Surface level memory: Surface level memory are the words and phrases that are actually remembered from sentence.
2. Proposition level: The propositional level is when you take the sentence and put it into simple idea units.
3. Microstructure: The microstructure is the propositions that give meaning to the sentence. This is when you take the words and make meaning.
4. Macrostructure: The macrostructure is the high-order units after putting these propositions together.
5. Situation Model: This is when the reader uses his/her background knowledge or prior knowledge to make sense of the sentence.
