Restructuring the Lit Review....

Right now I have my lit review draft with several new articles to add to it. I'm still having trouble deciding on how I want to restructure it so that it flows like a narrative. These are my ideas:

Previous Outline	Present Outline Ideas
Current Educational Context Competing Definitions of Inquiry-based instruction Framing curriculum The role of direct instruction in IBI The role of the teacher Benefits of IBI Limitations of IBI	Current Educational Context The Instructional Designs of IBI Competing definitions Focus on science Cross-disciplinary Recommendations Framing Curriculum The role of direct instruction The role of the teacher Benefits of IBI Academic Metacognitive Motivation Closing the Achievement Gap Limitations Minimal Guidance (the critics) Counterargument (in response to the critics) Insufficient research

 
 I'm still not satisfied with this, but it's a start. My outstanding questions to myself are: How should I end my lit review? Should I end with the recommendations section? Should I present my personal definition of inquiry in the beginning or end?

I also feel like I'm in that trap of searching and searching for more research studies that I can't seem to find. There have only been a handful of studies that have looked into the effects of inquiry-based instruction and almost all of them are limited to the application of science. Although this is not a complete disappointment, I am not sure how to support "my definition" of inquiry across the curriculum. All I have to back up my opinion are my beliefs and experiences teaching and observing inquiry.
