A strategy for (effectively) teaching (a foreign language) must involve conversation as a backdrop.

教学过程必须以交往为背景和手段。

Grammatically, I would make the following comments: "The process of teaching" is not an appropriate phrase. You should say "The teaching process" or better still "Teaching" or "Education" by itself. Also, "with" is not the proper preposition to use with a verb like "to ground". The preposition to use here is "in". Again, from a grammar point of view, your sentence should read:

Teaching should be grounded in conversation. 

However, if I now look at meaning, I would say that "grounded in conversation" does not convey the meaning of the Chinese sentence.

So, I think the best English translation of your Chinese sentence would be something like:

Conversation should be at the center of education. 

You can see that I have steered away from the structure of the original Chinese sentence, but in so doing I have retained the essence of what it meant.

I hope this helps.

加油！

It is imperative/essential to use communication with others as the backdrop for effective education. 

Just another idea! The other translations are great as well.
