Hello. This question requires a personal answer, where you must present your own opinions about the educational system. However, to help you out, I'll show you how I would answer that question. I hope this answer can serve as a model for your answer.
From my point of view, our current educational system has not been effective in preparing students for life. This is because our educational system is very traditional, and uses a structure where students are motivated to memorize concepts in order to get a good grade on the tests. This act of memorizing is very harmful to students, as these concepts are quickly forgotten after the tests are administered. Our educational system has failed to stimulate debate and discussion about the issues presented in the classroom. These debates and discussions allow students to be more participatory and learn the concepts rather than memorize them. Learning the concepts is much more beneficial because it allows them to remain with the student forever.
Assuming we're just looking at this phrase, "learn'd" suggests that the astronomer studied to become intelligent in the astronomical field.
