Synonym for 'learnings'

Solution 1:

A synonym for this would be findings.

Solution 2:

I would first submit that "learnings" is highly irregular, and you probably want to avoid its usage.

A good word here for you would be "findings" if you want a similar word that seems to suggest a broader scope when compared to conclusions (which is not a synonym at any rate).

Solution 3:

In a research project we have "results" which is a detailed account of what has been found, and "conclusions" where you present a summarized review of the results and add whatever implications they have for practical application, or further studies.
