mindmap root((PED<br>01)) pedagogy The art, science, or profession of teaching.
🌱His own pedagogy is extremely original; it sometimes alarms school officials but his students love it. 🌳Since in Greek *agogos* means "leader," a *paidagogos* was a slave who led boys to school and back, but also taught them manners and tutored them after school. In time, *pedagogue* came to mean simply "teacher"; today the word has an old-fashioned ring to it, so it often means a stuffy, boring teacher. The word *pedagogy*, though, is still widely used, and often means simply "teaching." And *pedagogic* training is what everyone majoring in education receives. pedant 1、 A formal, unimaginative teacher.
2、 A person who shows off his or her learning.
🌱At one time or another, every student encounters a pedant who can make even the most interesting subject tedious. 🌳It isn't always easy to tell a *pedantic* teacher from one who is simply thorough. Some professors get an undeserved reputation for *pedantry* from students who just don't like the subject much. Regardless of that, a pedant need not be a teacher; anyone who goes around displaying his or her knowledge in a boring way can qualify. pediatrician A doctor who specializes in the diseases, development, and care of children.
🌱Children in the U.S. usually see a pediatrician until they turn at least 15 or 16. 🌳Since *iatros* means "physician" in Greek (See IATR,) words such as *pediatric* naturally refer to "children's medicine." *Pediatrics* is a fairly new medical specialty; until about 1900, children were considered small adults and given the same medical treatment, only milder. Benjamin Spock was the most famous pediatrician of the 20th century, and his book *Baby and Child Care* changed the way millions of Americans raised their children. encyclopedic 1、 Of or relating to an encyclopedia.
2、 Covering a wide range of subjects.
🌱Someone with the kind of encyclopedic knowledge she has should be competing on Jeopardy. 🌳In Greek, *paidaea* meant not simply "child-rearing" but also "education," and *kyklios* meant "general"; thus, an encyclopedia is a work broad enough to provide a kind of general education. The world's most eminent general encyclopedia, the *Encyclopaedia Britannica*, is a huge work that covers every field of human knowledge. But *encyclopedic* doesn't have to refer to books; it's often used to describe the wide-ranging knowledge that certain types of minds just can't stop acquiring.


    PED comes from the Greek word for "child." The same root also has the meaning "foot" (See PED,) but in English words it usually isn't hard to tell the two apart.🌸
