correct the resume, thanks

Notes:

Highlight 1- You probably "designed lesson plans"? This involves planning what you will do in each class. (You may have also "developed teaching methods"? This would have more to do with changing how you present the information to the kids, the goal would be to present the information in the way that makes it easiest for kids to learn, and the assumption would be made that you were the first to think of them.)

Highlight 2- What context did the students speak in English? What did they talk about and where? From the information given I would say you "Helped students speak English" or "Taught students to speak English." (If you were actually just telling them that they should speak English, "Encouraged students to speak English" would be may appropriate, but I doubt that that is the case.)

Highlight 3- I think "Instructed students" would sound better here ("taught students" is also okay, but taught is less formal)

Highlight 4- What did you analyze advantages and disadvantages of? This is unclear. 

As a side note, is there a reason that you refer to students as "them" or "their" and not "students" or "students'"? Is there any reason you did not state the subject of the sentences? Both of these things are understandable, and could possibly be correct, depending on how you were told to format this. I'm entirely unsure of the formatting myself, it just seemed odd from a language based point of view.
