I am not basing this on my misconceptions. I am basing it on my observations of a class I was in. In the class I attended, everyone had a lot of trouble with conjugation. And the teacher did NOT teach plain form even at higher levels. It was taught as a "noun modifier form with no meaning on its own."
Beginning students can read texts with a dictionary if they know that the "masu" form isn't the dictionary form of a verb. The students in the class I was in couldn't use a dictionary at the end of the course. The should at least be capable of interpreting text with a dictionary at hand. When they asked about not being able to find "tabemasu" in a dictionary, they were told dictionaries don't match this style of teaching so don't worry about it.
It can cause more confusion in conjugation depending on how the teacher decides to teach it.
Quote:て form explanation:
はなします
いきます (to live)
あそびます
あびます
For はなします take off ます and add て
For いきます take off ます and add て
These are the same type of verb.
For あそびます take off びます and add んで
So if it's びます, it will be んで, but for あびます take off ます and add て
(Continue like this for all verbs the class knows.)
There isn't really a pattern. You just have to memorize each word.
That's the explanation. Looking at あそぶ and あびる it's plain to see they aren't the same type, but with ます only explanation, it adds some layer of confusion.
Personally, I find that more confusing that necessary. I know that not all teacher's do that surely. But when he said teach only the polite form it made me think of this method.
You obviously are for teaching polite first. I am not so much. I'm not saying I'm against teaching polite first. But some teachers teach conjugations while pretending the plain form of the verb doesn't exist. It all depends really. I am against the way I observed it being taught. That is all.
Edit: To clarify. I'm not against learning teineigo first. There is a difference in first and only. I think even beginning students should at least be aware of plain form.
