Understanding the Subject
- Understand the subject.
- Meaning/essence of the subject
- Importance/value of the subject
- Instrumental Importance (real-life importance)
- Mathematical Importance
- Educational Importance
- What are difficult about the subject for learners
- Decide what should be taught and what should not be taught.
Anyway, you must tell the truth, not lies.
So, understand each subject clearly yourself.
- And remember that there is a variety of "truth" (levels of "truth") :
"Truth" for students of primary 1
"truth" for students in a highschool
"truth" for engineers in a field
"truth" for mathematicians
etc.
