I found the reading really interesting. Although it focuses more in geometry and mathematics, I can see the connection between the approach of this paper and my teachable subject. The stories were relatable to my personal story. I always found something special about nature, I did not know what it was, but whenever I went on a fieldtrip, or just a beach or backyard I felt empowered. I always wondered what was the story behind all of the things we see at present. I also felt a fascination whenever I saw mountain or a tree. As I grew up, I understood that I had curiosity and a desire to understand nature, in my case planet Earth. So, we are sometimes motivated without no apparent reason, and today I know that I love Geology.
This particular subject has got a big component of abstraction, and recognizing it in our classroom is of vital importance.
The paper gives some examples of "undefined terms", such as point or straight. In Geology, it is really difficult to define time, because the perception of it is completely different. It is hard to imagine how old our planet is. If I think of geometry in Earth Science, I can come up with plenty of examples. The chronology of events in sedimentary rocks is defined by stratigraphic principles, which involve the geometric relations between each body of rock. If we want to know what is the course and ditch of a rock we need to measure angles, and so on.
Sometimes, we appreciate geology because of how it looks like, without knowing what is the mechanism that sustains what we are observing. In our classroom we can discuss these type of stories, which I consider of high value for learning.
There is a beautiful quote from Nicolas Steno that says " Beautiful is what we see, More Beautiful is what we know, most Beautiful by far is what we don't".
