The Maine Education Policy Research Institute has just published what appears to me to be a very useful study on parent engagement.
A summary of it can be found here, and the entire report can be viewed here.
I’ve only had a chance to scan it, but it looks helpful. One section that stood out to me was on student homework projects requiring family involvement. I don’t recall seeing previous research on that topic.
I’m adding this info to:
