How "speaking" is related to "The Input Hypothesis"

As I said, "The Input Hypothesis" is consists of five sections. I thought all of these were related to, but some of these are hard to understand what they are.
（１）The acquisition-Learning Hypothesis　（習得・学習仮説）
Aquisition: learn language naturally , unconscious
Learning: study what language is, conscious
They are characteristics.
Regarding speaking, I'm not sure what "speaking naturally" is. From this point of view,I'm going to ask JHS
"What kind of activity is needed to speak naturally in English class?" and
"Do you think you have enough time for speaking?"
Through these questionaire, I want to understand what "Speaking in JH these days" is like.

（２）The Natural Order Hypothesis （自然順序仮説）
Actually, I don't understand whether it is related to speaking or not.
We start to understand some English words which is something easy.

（３）The Monitor Hypothesis （モニター仮説）
Monitor: The function(or working) that some grammatical knowledge may effect our speaking activity.
Three conditions are needed for us to work "monitor" well.
① We have plenty of time to corect our mistakes
　② Pay attention to linguistic form
　③ We have grammartical knowledge to some extent

It is said that English teacher should try to give "correct English (information)"when students make mistakes. It helps learner to do feedback unconsciously. Never say "You made a mistake"!

I have to make it clear that what kind of instruction is effective when students speak.
"What kind of instruction do your teacher give when you make mistakes in speaking and is it good or bad for you?"

（４）The Input Hypothesis　（入力仮説）
Language materials should be easy to understand, interested. Speaking isn't grammar, so teachet should pesuade students to make mistake when they speak. I want to know what kind of materials are effective for English learner.

"In speaking,what kind of activity are you interested in, and why?"

（５）The Affective Filter Hypothesis（情意フィルター仮説）
Learners should be opened for Input. And we need good (relaxed) atmosphere in English class. For example, at the beginning of the class, speaking plays an important role.Yes, anything will do. Greeting, what you are interested in, what day today is etc…. It's fun for students.

"When do you think there's something pleasant in English class?
speaking, reading, listening, and writing? why?"
