Figuring out the Big Picture of the Research

I need to figure out the big picture of the topic of my research if I want to finish my research projects in an effective time and way. (Pinterest).

I need to figure out the big picture of the topic of my research if I want to finish my research projects in an effective time and way. I must not get trapped by many subtopics to discuss during my studies so that I may get lost and never finish the projects. 

Currently, I am studying the relationships between culture, identity and language teaching and trying to know how they intersect especially in the practices of language teaching and learning. The result of this study will lead me to some pedagogical implications that teachers may consider when they undergo their professional works.
