At Del Mar College in South Texas, our intern students are currently not allowed in childcare centers. So their activities that they design/plan can not be carried out. What we have done is to modify the "ending reflection" in their activity plans. Typically the students would of written about what worked, what didn't, what they would do to enhance the activity next time, etc. Now the ending reflection is the student has to give at least 2 ideas on what they would do to help a particular situation (a child is language delayed, the child lost interest in the activity, the child has a motor disability, etc.)
As far as their interactions with young children, for our employed interns, we are allowing our students to set up Zoom to allow us to watch them interact/do an activity remotely. For our non-employed students, we are allowing them to complete their activities with children they have access to (their own children, neighbors, family members, etc.). Then we can come watch them carry out their activities in their front yard or local park, or if the activity is inside, they can set up Zoom and invite us to watch.
What we are concerned about is making sure our students get the minimum required number of hours, which for us is 96 hours. So we are thinking of alternative experiences that may be allowed that don't allow contact with others, such as helping prep activity materials, classroom set-ups, bulletin board for parents, shadowing (from a distance) a family advocate, etc.
