I think that depending on the goal a person chooses to get from a situation determines how they perceive an issue and a solution. Many aspects shift a person's mind to find a solution, depending on what caters to them. For example, what classes to take may be conflicting when there are so many to choose from, but people solve this by choosing the classes that go alongside their major or, depending on graduation needs, as it caters to their goals. So people use problem solving skills in order to choose which courses fit best for them.

With English being my second language, I tend to often be imprecise when trying to get my point across, as I myself get confused with what I'm saying sometimes. For example, when I'm trynna narrate what happened in my day to a friend, I tend to mix up a lot, especially when I say he/she. I mistakenly interchange them when narrating, so it becomes confusing to my friends to understand, but I try my best not to get them mixed up.

My AP Bio teacher would constantly say that the Kinesin Motor Protein "walked" in order to relate a movement done in everyday life to that of the delivery protein. This worked because it put a clear image as to how it moves; however, walking tends to be at fast/medium speed, so although it illustrates how it moves, it doesn't demonstrate the speed as Kinesin moves slower than a human.

I interpret a mental model to be the structure a person builds as they learn material and receive knowledge, not only in school but as a whole. The things humans learn and how their brains process them, making a mental model of the subject they're learning in life, in order to be able to recall.
