Step 1 && Step 2

Step 1
It is okay to say things the instructor might disagree with. --- I believe that this is possible, only because if you are writing a paper, you are not trying to impress the teacher. You are not suppose to say things you "think" the teacher wants to hear. It's better to write about something that is more describing yourself. It's better to write about your own opinion. Just pretend that you are writing to impress yourself and not any other. Who cares what people think.

You have to know a thesis before you start. --- I think it's better to know what your thesis is because it may make your paper a lot easier on you. It helps you with ideas throughout your paper. Also if you did not star with a thesis, how would you know what to talk about?

You can't use the pronoun I. --- I think that in a research paper, you should not use the word "I" unless you are stating an opinion. I just think that using "I" in a research paper sounds a little odd. But then again, I think you can use it???

You can use your own voice. --- In a researcher paper, I believe that you can use your own voice to a certain extent. I believe that you should be allow to write about thinks as if you are stating an opinion but it should go to far.

The information should come from books. --- Not all information comes from books...they can come from the internet, newspaper articles, news channels, etc... Information should come from books though.

Step 2

Pretty much everything you read in textbooks is true.--- Yes, and no. You basically cannot believe everything that is in textbooks. You can to a certain extent. They may be 98% of the time right but there's always that 2% that they can be wrong. For example, in a history book, there could be some facts that are stated, but later in years it could change. Just for saying how they say history does not repeat it's self. I'm pretty sure it does, or will somehow down the line. Also, another thing in textbooks, for example Science...there may be different diseases or illnesses that were once called something or scientists thought is was something but really it was called something else.
