Hi Saroj,
This Advisor does not fully understand your question and requests that you resubmit it with more information about what learning you need to facilitate and assess. CTB has some general information about facilitation of learning, and you can access that by entering "learning facilitation" (WITHOUT the quotation marks) into the search box at the upper right of our page. However, I am not certain whether it really addresses your question.
Are you needing iinformation about learning facilitation models or about how to evaluate the results generated by two different models? If the latter, take a look at Evaluating the Results of the Intevention in the table of contents under Learn A Skill. Also take a look at the Toolkit enntitled Evaluating the Initiative found under the Learn A Skill heading.
