What does negotiation mean in this context:

Answer

Most of the answer people put are incorrect.
"Negotiation of meaning" is an educational term. 
It means that when someone is speaking, you ask them questions to elaborate in more detail what they are talking about.
EXAMPLE:
Teacher: How did you enjoy your vacation to Germany?
Student: It was fun.
Teacher: What was fun?
Student: It was fun to see stuff there?
Teacher: What exactly?
Student: I enjoyed seeing the buildings.
Teacher: Which buildings did you see and why did you enjoy them?
Student: I enjoyed the architecture of the Cologne Cathedral.

etc.
So you are having the student speak, and guiding him or her with clarifying questions to help them speak more and in more detail.
That is what I gathered from a Google search in:
"Negotiation of meaning theory"

Answer

Negotiation: A conversation between two or more people to arrive at a result all parties agree with.

For example, when you are in the market and you are negotiating a price. Or when you want to go out with your friends and your mother is not giving you permission. Your parent's  want you to study engineering because this is the best option to get high salary jobs.
 But
 You want to study business because you want to become an businessperson.

So, you have to convince with your parents.  At the end you and your parents agree with your decision or may  be  you  accept  your  parents  decision. 
Another one an example:
You are customer going to market to buy a mobile . You ask to the shopkeeper how much price of this mobile ?
Shopkeeper said £1000.
You said , will you sell the mobile£500 ?
Shopkeeper : No ma'am, you can buy £600.
After all , you said that I will buy £700 and shopkeeper agree with your price .
This is called Negotiation.

Hope  that  it  can  help you.

Answer

Negotiate has a secondary meaning of “to travel through” or “climb over”. As in “the wagon negotiated the river successfully”.

Answer

It means figuring out of the meaning of something/having the skill to be able to figure out the meaning of something

The way I read it, it's as if you are metaphorically negotiating with the concept itself to figure out what it means
