The Problem With Asking Questions

I have read about effective feedback.  I try to give feedback on student work in a quality manner,  I really do.  I try to limit it to what I observe, make it actionable and goal-oriented, and limit the amount of advice I give that takes all of the reflectivity and thinking out of the process for students.
But sometimes I forget, and do stupid things like ask questions.
My students are working on integrating science stuff in the context of problem-solving for their final exam projects right now (more about those projects later).  They screencast where they are with their solutions at the end of each period, and I watch/listen to them each night, leaving feedback for them on the assignment in Edmodo.
For some reason, last night I felt the need to ask questions of each student after reading their rough drafts of their solutions, giving them questions for consideration before they work on fixing and finalizing their solutions.  I diligently listened, watched, and tippity-tapped away for two hours, and then asked students to honor my feedback by reading it and making changes based on that feedback.  Their instructions were to research the questions and use that research to create a step-by-step solution.
As soon as I let students loose on their feedback, about half of them either pulled up a Google Doc or pulled out a sheet of paper and began copying my questions down.  One student shyly raised her hand and asked me, "When do you want these questions turned in?  By the end of the period?"  A few other students then asked me something similar.
I was floored.
Sometimes the problem with asking questions is that students act out the script they have memorized for years: Teacher asks questions, student answers them and turns them in.  Stimulus, response.  Factory-model trained, with no experience with having "knowing stuff" be the first step to real learning rather than the only step.
Next time I will know better than to ask questions when giving feedback.
