A good teacher possesses two key aspects(qualities). Firstly, as an individual, they must
have the passion to acquire knowledge and share it with others. Secondly, from a
technical perspective, a good teacher knows how to impart the same knowledge to
different students, how to extend the topic in multiple ways, and how to adapt
the knowledge to various areas based on the developing needs of students. Most
importantly, they must know how to inspire individuals(students) to become self-developing
teachers(individuals) with a growth mindset.
"Learn/study knowledge" is a common mistake. Instead, you can say : acquire or gain knowledge.
Likewise, "teach knowledge" also doesn't sound right. Better options are : pass on/impart knowledge.
I could not understand the last paragraph. I inserted some suggestions in brackets but I'm not sure if this is what you wanted to say.
