RuthAnn,
Water2wine is doing a great job of talking through this with you!

We're just getting ready to head out to Rochester tomorrow A.M., so I'm just stopping in for a bit. But, I noticed your question and thought I'd let you know what we were thinking when we added the research assignment to the CTC guide. Depending on how old your student is, you may approach the research different ways. For a child who has already been through Preparing Hearts and has had your guided help training them how to do the research section, the research within CTC can be more independent. For those who have not been through Preparing, the research will need to be more parent led in CTC.
Within the CTC guide, we're thinking that there is more than enough writing for a 9-11 year old, so we planned for the research questions to be answered orally. If your kiddos aren't giving you the answers you're looking for, I'd sit down and help them through it. For research, you're wanting them to learn to skim for information, use headings within an index or table of contents to guide them as to where to look for answers, and also to be able to summarize the answer succinctly when they retell it to you.

For older students, asking them to write the answers would be fine too.

We will have kiddos synthesize their answers into a postcard response format for research within RTR. So, the oral assignment within CTC is a step in that direction - preparing them for the written part that is to come.
Hope that helps!
Blessings,
Carrie
