Skewing the Research

Of the reading I have done so far, half of the researchers believe that tracking is an educationally sound idea, and half of the researchers are opposed to it. I am sure that I could easily ignore half of the research, and find sufficient proof of any theory. My task is to create a research question that will force me to look at all of the previous findings, and create my own valid conclusion, vaild being the operative word here. If anyone out there has any good guidelines to help me to develop a research question, feel free to share!
