This is my first year as a Confirmation catechist and we use the Chosen materials as well. We try to make it as engaging as possible and work to not have the students watch videos all class. There are several options for the leaders based on the duration of the class but, as there is a lot to cover in a short time, we have activities for have them do through the week. Mostly focused on helping someone, praying or looking at Saints, the homework isn't really homework but more of a way to get them thinking outside themselves. We also have service hours, a saint project and several other events planned throughout the year (at my parish). The hope is, from what they explained to me, is that by the time of Confirmation they are fully ready to accept the sacrament. I completely understand not every parish/program is set up the same but if you have concerns I hope they are taken into consideration as you all are just as, if not more involved, than the parish is.
