Is there a standard instrument/method to assess the effect of blended learning (or ICT in general) on a person?

I am wondering if there is anyone out there who has tried to assess the effects of using technology vs conventional method or what particular ICT method and what was measured through the use of that platform in education?
I am going to conduct a study on the effects of Integrating technology in education, but I am still vague as to what I have to measure first.
So I need help from the experts.
